supposing the cylinder w to be in motion and the traveling .roller to be in contact with* it. as -shown in -the drawings, Fig. l., the said traveling roller will advance toward one end of the cylinder until it shall have approached near to it, when the lever fn will be brought -in contact with a projection which proceeds from the lower part, d, Fig.,2, el' the ports the parallel'rods, f' g. and is-near the said end of said cylinder. The said projeetion, by means of the continued advance-V nient of the traveler toward and against it, elevates the said weighted levcr'n' and forces it over, so as to throw its center of gravity' on the opposite side of the rocker -.shaft k, toA which it is attached.` The said wei hted le v er in 'falling over will turn said roc er-shait in its bearing, and by so `doing will elevate the cross-piece l. and so as, to carry the pin or screw i", which goes through the slot d, Fig. 8, made through the connection-rod my in contact with the upperl end of thefs'aid slot, and thereby raise* the connecting-rod m* and tbe-end or part of the franie of the roller tl and reverse the angular position of the said' roller, -whereby it will be caused, by therottion of the cylinder w, to travel toward thesaid cylinder. Having reached the said end, the said weighted leverv will meet another projection from the opposite scroll, which supports the opposite ends of the said parallel rodsf' g. Said projection will in itsturn reverse the position oft 'ie said vweighted vlever and the traveling roller, or move the same back` again into their original positions. e.

The distributionacylinder w ma be made of wood; or it may be constructed o metal' and be hollpw and tight, so as to be capable of holding water or steam.

ne i *s These slots permit the-.pointstocks to be moved around in any necessary position,.to make registers crosswise or lengthwise of the sheet, as circumstances may require, without rendering it necessary to remove the bolts bywhich the said stocks are secured in v their places, and without separating the points or their stocks from the machinery which operates 'them or from the parts-which hold them in their places.

The four holes m n o p, Fig. 13, which are.

made through the Yiron plate of `tl1e tympan and for the peints n n? to project through, must also be made curved, and long enough to allow of the necessary variation ofthe points from central lines across the tympan. The sheets to be printed are successively laid by the attendant in a central position on the tympan above described. The points, having been iirst properly adjusted and secured in their places, so asto produce register, are thrust through each sheet by pressing the sheet down upon them. y

The nippers which take the sheets from the tympan are constructed as follows: There should be several sets for each press, (two or more pairs in a set, as the length of the sheet may require,) each set di'ering in length from the others, according as' the sheets to be printed may vary in width vone from another, the

widest sheets requiring the shortest nippers,

and the narrowest sheets requiring the longest ones.

V` g r', Fig. 1, denote the nippers as they appear the moment before being closed for the purpose of seizing the edge of a sheet.

s, Figs. 1 and 9, is a rod, which extends Y across from side to side of the frisket-carriage,

and is so aiixed to said carriage as to t-urn in bearings in its side rails.

Thenippers are composed of thin plates q 1, of steel or other suitable material, jointed together, so as to open and close on said rod s iu a manner similar to that in 'which the around the'rod one end 'oli/each of said springs being attached by means of thecollars and set-screws, as seen at u u, to said rod.

The other end of each of said 'springs is attached tcroue of the said lower halves or parts A s-y a means by whichy the lower halves of the nippers may be kept in a horizontal position, while their upper halves are elevated,

and by-whieli the time of closing said nippers together may b e controlled, ,there is aprojeetion, u, which proceeds from the lower part of the hinge part of each lower half or part, These projections, while the lower blades gif-545)( main under 'the projecting hook of a catchd immediately moved forward by the action of gravity to its place over the projections u u', as shown in Fig. 1. The lower-halves or parts of the nippers will be thus held in ahorizont'al position until the proper moment for them to be raised upward. -At such time the hook of said catch-bar is drawn away from the projecl tionsuu, and this permits the springs t tto force np the lower blades, rr, and close them upon or against the upper ones. The upper blades of the nippers should be madeso much longer than the lower ones as to allow of their lapping about an eighth of an inch onto the lower edge or bar-of the tympan, the lower blade being short enough to allow it to be brought up against the upper blade without.- touching said tympan. Itis necessary thai?- the horizontal motion of the nippers toward the tympan or feed-board should .be stopped 'a littlebefore the frisket-carriage has'arrived at itsv extreme limit of motion toward the right-hand end of the machine or away from the platen in order that the said nippers may seize the sheets when they (the nippers) have no other motion than that o'f the closing of the two halves or blades toward each other and the sheet between. them; otherwise the sheets might be so jarred or movedfrom their places after having been pointed as to spoil the register. lthe journals of the rod s are made t-o enter grooves made horizontally in the edges of the perpendicular parts ot' the side rails of the i'risket`. carriage. To keep the rodl s pressed irmlyvagainst the inner end of said grooves, and lat the same permit it 'to slide longitudinally in the grooves, small pistons or slides rv a, Figs. 1 and 9, are respectively inserted inthe ends of' the hollowcylinders y yl, in which are helical springs to press said pistons out in su'eh manner as'to cause them to en ter said grooves and to press firmly against the journals of said rod s3.

For the convenience of taking the rod s' out of its place in order to change the nippers or for any other purpose, one end of each of the 'cylinders y y* is jointed to a projection from studs a" a") the other ends of said cylinders to be raised up sufficiently to permit said rod tovbe removed.

tiy 116 part. by meausot .asxnall frlctionroller, et; ig. 9,'aixed by means of a screw pinor pivot 'to an armpa, which projects from one end of the rod .v and at .right angles to said rod. The said roller operates in an irregular or crooked pieces ofthe press-frame. r1 Y y The nippers perform theiroiice in .the following manner: Let it be supposed' that the machine is'in motion and that a sheetof pa-Y per has been properly pointed with vits lefthand edge .projecting far enoughover the' lower edge orbar of the tympan for the nip?. pers to take irni hold of it,` also that the nippers are just advancing from under theplate'n.

At this moment the friction-roller zwill ein-1 ter the before-namedgroove lb, which issocrooked as to force the said roller downward,

and thereby while the nippers are advancing toward the tympan cause the rod or shaft yil" to turn in its bearings and elevate the upper blades of the said nippers high enough above the tympan to pass over the edge of the sheet of paper on it. .Said nippers continue. to `move on until they have approached, quite near to -the tympan, when, by an opposite bend in said groove, said upper` blades are made to descend suddenly upon the sheet of paper, their endsbci-,ng' made to lap, as be-l fore named, about an eighth of au inch over the lower edge or bar of the tympan in order' to secure the sheet in its place. At this monient the projecting ends of the rod s should be made to meet stationary projections c* d* on the sides of the presen-amc, and so disposed as to arrestthc .further progress of said rod towardthetympanor feed-board. The-frisketcarriage, however. continues to move on a short distance or until the catch of thev bar v is advanced suiiiciently to disco-gage the projections u u3 of the lower blades of the nipf pers, which having taken place the springs'ta t will `instantly throw up said lower blades and secure the sheet firmly against the upper ones. Assoon as thenippers have been thus made to seize the sheet, the frisket-carriage will be made to begin its motion toward the bed and platen, which movemept at first willl cause the points to be drawn from the sheet,

'as above described, the springs in the hollow cylinders y y, causing l the rod s at the same ytime to' recede in the grooves in which its pistons fz' play and resume its proper bear-- ings. Said rod s will then leave the rpjecore. and thefrisket-carriage continuing to move toward the bed and platen, the sheet of paper .will be drawn by the nippers from the tympan or feed-board, the said nippers by the ac,- tion of the aforesaid groove on the frictionroller-'z' being made to travel back through the same track inwhich they had moved in the opposite direction and made to resumen horizontal position just as `they arecarried between the bed and platen, the sheet as it slipsfrom the tympan being caused to fall and top off the frisket-carri groove,4 b, Fig. 3, made ina'plate', xcd on the inner surfaceofxone, of the side y introduced ina-horizontal position. between bereccived-'up'on the frisket "e,y which is of the ordinary.l character, and rests upon thee t,where it is'k in its place by steady-p ns 'or other suitab e contrivances. .Thus inthe above-specified manner ,thel 'sheets are 'successively drawn from the'tympamdeposited on the friske t,'and

be made movable, and' may -be operatedby` means lof leversnand rotating cams'or their equivalents;y 'By such means the nippers may be made to` fasten upon Ithe sheet vv4 ile *their horizontal Vmovement is stopped, or v {othervwise, as may befound advisable.

One peculiarity,4 in `-the operation of the above-described nippers consists in their bcing made -to secure the, sheets'from-movement on the tympan, this being effected by means of the upper blades of the nippers, as aforesaid, and before said nippers are entirely closed. Another peculiarity in the same con- Tsists in said nippers being made to close upon the sheets while their horizontal motionis arrested, both of which characteristics are ilmportaut in order to secure good register.

The following isanother mode of constructing thenippers and `the parts which operate them, by which the same advantages are attained: i v

. Fig. 10 is a top view of one half of the' frisket-carriage, so modified as to be suitable to receive aframe,which I call a Lf nipper-frame, now to beV described, and which is calcula-ted tol carry' and operate the nippers. Fig. 11 is a side elevation of the saine half of the fris- 'ket-carriage, together. with one half ofthe nipper-frame, having a pair of 'nippers secured it, said nipper-frame being so' elevated as .to bring the nippers in the position they' would occupy at the moment of taking hold vof the paper on the tympan. Fig. 14 is a top view of the nipper-fran1e complt e,'and sepa"y rated Vfromvthe frisket-carriage. It is com# posed of several parts, as follows: Fig. 15 is anionter frame, which serves as a stock tof attach yallthe other parts to.- Fig. 19y isa view of the end' of saidy frame with the friction-roller' f by means of which said frame is elevated and depressed when in operation. Fig.' 20 is a view of the other end of said frame. The said frame is 'suspended inv the frisketcarriage by means of the pivots g g. Figs. 1.4 and 15, which are made to enter holes lmade through the projections, (one of which is seen at h,1"igs. 10 and 11,) which are raised for -the purpose from the two corners of the frisketcar-riage. These pivots may be` put into holes made for that purposein the ends of the main stock, Fig; 15, of said frame; and said pivots may be caused to project therefrom by helical springs placed in the bottoms of said holes. 'When so applied 'to the saidstock, the said 'pivots may be pressed in even with Y ner frame, l. Fig. 16.

On the inner side ofea'ch ofthe end pieces ofthe main stock, Fig. 15, of said frame are grooves made and covered with thin pieces of steel ii. calci lated to receive the end pieces, k* k, of an Fig. 18'is a view of one end of this inner frame, and Fig. 1\7 is a view of the other end. Whcn said inner frame. l, is in its place, the end pieces, kkflie in the aforesaid groovesin .thc inner sides of the end pieces of the said stock', where they can be 'moved nt about half an -inch, but are prevented from slipping any farther out than may be proper by means ofthe two little screws mv m', Fig. 14, put in'to holes, which may be seen at n n, Figs. 17 and 118, the heads ot said screws being made to come against the ends of the plates .1 i* when said inner frame is pressed out to the place it generally occupie by means'of the flat steel spring o, dispose asseenin Fig.14.

Each nipper is' composed of an upper half, p, (which is made of n thin plate of steel bent nearly into a right angle, as seenin Fig. 1l.) and a lowerl half, which has a hinge-joint at e r, the part below said joint being riveted or otherwise secured to that part'ot' the upper half which `is below the angle thereof. This said lower part of said`upper half is that by which-the nipper is secured (by means of the screw s, Fig. 11) to the middle bar of the said "inner frame, l. (See Fig. 11.) t* t, &c.,-`Figs.

14 and 16, are screw-holes in said bar, in which the screws which secu-re the ni ppers to it are fr, Figa 21 and 11. is a fiat im, whims.n fixed upon the outer face of the bar to which Its duty, which is Screws, such as are' denote by Fig. 22, and having friction-rollers, as seen in Fig. 2.3, are put through' peculiar diagonal shaped slots v u* o, Ste., of said bar, and are screwed into corresponding holes in the middle barof the frame l* in such manner as to allow the bar u to be slipped back and forth endwise, in order to cause said friction-rollers and screws to work freely through the whole lengths of the the slots. Now the end wvof the bar u is iitted to the inside of the forward end. of the right-hand end piece of the stock in the manner of a miter-that is to say, both are made angular or beveled, as seen in lFigs. 14 and 15 so that when the'inner frameis pressed in toward the main body of the stock the beveled end of the said end piece of said stock operates against the endoflthesliding bar in the iiianner of a cani or wedge,and causes it to slip along on the middle bnr of the frame Z, where,l 'by the friction-rollers, Fig. 23, and screws, Fig. 22, are caused to operate through the said diagonal slots ve, &c.

when by a sudden bendfor turn downward in said groove, or by the operation of a cam or other mechanical equivalent, as before mentioned, the ends of said upper part or parts of the nippers will hebro'ught suddenly down uporhthe lower edge of the tympan and the instantthis occurs projections c, Figs. 11,16,

- 17, and 18, from the eornersof theinner frame meet projections c* d', Figs. 2 and 3, from the sides of 'the frame, which arrest the further progress of that part of the nipper-frame and the'nippers; but the frisketfvcarriage and consequently the main stock of the nipper-frame continuing to move on for a short space furfther, the said inner frame, l,v'.i.1`ig.v 16, is

pressed in toward the main part of the stock suicientl y to cause the beveled end w of the end piece, :zpof said stock to operate on the sliding barn* and 'causeit to close the nippers upon the sheet, as above described.

The movement of the frisket-carriage in the opposite direction carries the sheet in between the bed and platen. the same as in the case of the nippers first described. The bar u* is thrOWnback so as to relieve the pressure of vnippers upon the paper, as follows:

y, Fig. 2, denotes' a wedge or cam affixed by one end'b'y means ota screw, pin, onpivot, z, tothe side of the frame of the machine in the manner of a latch or click, its place on the 'side of the frame being such that very soon after the nipper-frame shall beginits motion toward the right-hand end of the niachine the'end goot' the. bar'u will bc brought against the wedging part a?, which will cause said vbai-to slidebaek endwise, its diagonal slots at the same time allowing it to drop down4 and thus to relieve the lower blades of lt-he ni'ppers, so that said rippers shall open to receive the sheet as the nipper-frame shall beelcvatc'd, as before described. WVhen the nipper-frame, with the ni ppers closed, shall-be in motion toward the 1eft-hand end of the machine the end y 'of said bar u* will be brought in contact with tlie under side of the wedge y, and will elevatelit seas to pass under it.

As soon as the bar passes beyond the wedgeclick, the latter wi-lldrop back to its place of rest, whereit will be ready at the proper mo ment again to operate on the bar u,` as aforesaid. The bed on which`- the form of types is' secured to said bed, and made to project into othervertical grooves formed on the sides lof the frame at j, Figs. 2 and The braeingrods g5, Fig. 1, also serve to preserve the horizontal position of the bed.

'over the top of the 'platen and forms a part mf n, Fig. 1, are progressive levers, called togglefjoints sons to bring the types in contact with the sheets against the face of the platen with suitable force to produce the im pressions. The lower end of the lower one,

In?, rests on a. ledge, o5, projecting from the sideof the bottom bar at its lower edge. The upper end oi the upperone, m5, is made to opcrate against the under side of the bed, asseen atp, Fig. 1.

The toggle-joints are operated by means of the alternator which is in principle of construction and operation very similar to that described for operating the l'risket-carriage.

r" is a friction-roller, against which the alternator acts to throw up' and straighten the toggle-levers. Said roller is placed on the center joint-pin, si, andin a slot,'t*, about four inches wide (the length of the roller) yin the middle ofthe togglcs, said slot being made to extend from u? in the upper lever to v in the lower'one,'and forms a suitable opening for the alternator q* .to play through.I 3

The lefthand end of the pit- Vvman is forked, so as to receive the upper part of the alternator qi between its two dat prongs. The pin :v5 is put through the said prongs and through the crooked slot y@ in said alternator'.

down again is as follows:

' crank j', Fig.

by which the bed is succes-l impressions are produced.

which slot has an abrupt depressionat one end of it, which formsa suitable bearing for the said pin av. The operation o f the alternator in straightening the togglejoints, elevating the bedpro d ucing the impressions, and lowering vthebed Leit be supposed lthat the machine is in motion, and that the 7, .by means of the pituian, has` thrown the alternator forward 'toward the toggles until the part indicated by the dotted' line z5,Fig. 1, has-arrived as far as the center` of the friction-roller 'r2 -The side of the month of'said alternator toward the crank will now forni acurved inclined plane on one side ofthe main part of the said alternator, which, continuing tol advance, will now act against the roller 1*", so as to press it forward, somewhat in the manner of a leverof the second class, (a6 being the ifuleruni,) and will cause said roller toroll 'up the saidcurvedinclined plane until the -togglejoints are brought nearly into line with each other, andthe-impression. is produced. The instant the impression will have been thus produced the crank f will have passed its line'of centers and will begin to draw back the alternator, which,I by a re verse action against the friction-roller 1"", will bring the toggle-jointsand the bedin proper time to their `places of rest, as seen in Fig. 1. That Ipart of this'alternator from-bi t9 c is formed as an arc of a circle whose center is in the fulerum a.' of the alternator. to keep the toggles and bed down steadyin their places during the time when 'the types are being inked by the inking-rollers.`

The armf at one end of said -shaf't has a frictiomroller, l,

ath xed near to its outer end. Said shaft is so placed ns to bring said. friction-roller under the curved part m of said slide. The arm rf on theother end ofsaid shaft should beniade Its odicefis iraix said. slide, and thereby elevate the said slide and the pitman, so as to cause Asaid pin x to pa'sds into the upper partof the slot, as aforen?, 1, denotes one oftwo or more spiral'springs, which are made to counterbalancc the we ightof the bed 'and the forms of types. They rest'at the bottom upon a sort of frame, o', the rock shaft or .bar p, which constitutes one side of said frame, forming a rocker-shaft 'with gudgeons at its ends, which rest in bearings qq?, Figs. 2 and 3, made on the sides of the frame pf the machine. This frame o is connected, by the arms projecting yfrom each end'ol` the rock-shaft, with two vertical connecting-rods, one of which is .seen at s,

the two upper ends of which are vjointed totwo corners of the bed. The upper ends of fthe said springs are made bear against a crossbar, `t', jointed to the ends of two levers, one of which is seen at u, Fig.1,. extending, respectively, from fulcra fixed tothe bed. The piul of the upper joint. of the Aupper toggle pales' through both of theselevers. By means of this device the toggles are ,held u-p against I their bearings on the under side 'of the bed in such manner as to allowI the wedgev, through the .action of a screw, :c; to be drawn out or forced in between the -bed and the piece w', which constitutes a y ring' for the said pin, the same being for the purpose of lessening or increasing the impression by lesseniug or increasing the distance between the upper joint ofthe toggles and the face of the bedV upon which the forni of types rests,

gfy y* y', Figs. 1 und 24, are wheels, which sustain the platen upon the horizontal railways formed of the upper edges of the two side pieces, Figs. 2 and 3, of the frame. These wheels, which sustain' the platen, are xed to the ends of shafts zfz?, which have journals thatnuu vin bearings at a afa a', Fig. 24. The ofce of said shafts and wheels isto serve as a carriage, by which the platen may be easily moyed'from over the form of types and back when such form is tothe changed `or an other pnt on, or for any other purpose. The parchment tyi'tpan' is securedfto the face of the platen by ,neans of a frame, b. Figs. 1 andf24, which is made to surround the edge o f the platen, and is secured inritsplace by slide-bolts or other proper contrivances. The blauketing is -put within this tympan and'between the parchment and platen.'

The tympaugsheet d, Fig. 25, consists of, a long sheet of paper jur other suitable material, which is to be rolled up on 'a' roller, ci, Figs'. 24 and 25,=-which roller is suspended by its'jou'rnals in bearings attached to one side of .theplatem From this roller the endof the sheet is taken and passed under` the platen, so aste cover that part which the types are' to be pressed against when an, impression is produced, and secured to another. similar roll` er, el, situated at the other edge of the platen, said roller e being-suspended by its journals in bearings, lwhich rest on springs a and are.

jointed to the platen at b, The said springs are forthe purpose of causing the rollers to take up any slack which may occurin consequence of a stretching of the sheet, and also to allow of the rollers conforming to any difference of length which there may be in the two edges of the said sheet. These rollers, together with the parts connected with them,con-

- stitute a. convenient device by which the tympan-sheet is well secured over the face of thc platen and easily and quickly exchanged from place to place whenever that part of it against which the impression maybe produced may become soiled. `Vhen a place on said tympan hasl become s0i1ed,'the rollers c' e are to be turned inI such manner as t8 unwind the tympan-sheet from one roller, and to wind'up the soiled part of said sheet on the other roller. Thus a clean part of said'tympan-sheet may be successively` drawn over the face of the platen, accord= ing as circumstances may require. When said sheet nas been drawn smooth by said rollers,l

`they are secured from turning back (so as to unwind or loosen said tympan-sheet) by means of pawls f f (c: other suitable meanSJBaid pawls being aixed to the platen and respectively dropped into the teeth of the ratchetwheels gT c', tixed on the ends of the said rollers.

-Fig 25 is a separate projection of the tympan-sheet and the rollers c cT for operating it. hjz are handles, by which said rollers may be turned around. The ends of the sheet'are secured to said rollers by putting each of them .into a groove, c and e", Fig. 1, (made along in the side-of each of the said rollers,) anA alterward pressing a rod into each of the said grooves, so as to wedge and confine thefsaid sheet to the rollers.

- In Fig. 1, denotes a movable table, which.4

stands on and' above the platen, Aand may be nnshipped at will by the operator, and is lintended '.to receive the heap of paper from which the sheets to be printed are to be successively removed. The sheets, after they `have been printed, are successively separated from the types. and removed from the press and laid -upona table, as follows: In Fig; 1, e denotes the frisket.` It consists of a. square frame made of thin iron, and covered with strong paper or other suitable material in such manner as to leave suitable spaces for the pages of types to project th rough in order to produce an-impression lon any sheet which may lie upon said frisket. This frisket rests onthe top of the frisket-carriage, and is kept in its place vby means of steadypins, which ought to be so put into said frisket and carriage as to allow said frisket to be moved up and down a little in its place, and also to allow of its being'v easily removed from the' carriage. Successively after each of the impressions have been produced on the sheets of paper the frisket holds the said sheets up while the types are allowed to sink down, and thus said frisket (together with the nippers',which at the time hold onto the sheet) screw pin or pivot near toi riedinto when the bellows is opened.

1o no servcsto overcome the adhesion ofthe ink,

and to separate the sheet-s from the type, this being the beginning of the process of removing the sheets from the press. After each of the sheets of paper has thus been separated from the type, the frisket-carriage begins its motion toward the right-hand end of themachine, and each sheet is carried out in a horito answer the purpose, whose oice is to withdraw successively the printed sheets from the frisket and present them to the action of an .instrument which I call a fly, which being accomplished the said instrument removes the said sheets from said system of rollers and bands and throws them on the pile or table, or other convenience provided for thepnrpose, as follows:

Fig. 7 is a detail view o f most parts of the ="takingo apparatus as seen in'their relative places, the spectator being supposed to be "standing at and looking toward the right- 'hand endA of the machine. l ;v k", Figs. 1 and?, denotes a bellows, which issustained in. its place by proper means.

YSaid bellows has` two long slits, l l', or. any

proper number of holes made through its top board, the same being to allow of the escape f, of air upward when said bellows is closed,

and for the admission of .air when it is opened. This bellows is operated as follows: l mi, Figs. 1 and 7, denotes atransverse-rocker-shait sustainedby itsl gudgeons in proper bearings on the ysides of the Trame. This rocker-shaft is provided 'with two arms, n' nl, which extend underneaththe bellows for the purpose of operating it. Said shaft is also provided with anotherarm, o?, which extends in an opposite-direction 'to :tha-t of the arms n' nl, and has a friction-roller, p1, affixed on a end. Said vroller is vfor the cam q', whichis aixed to the shaft i, to operate against. v f i 'i'7 s another arm, which also extends from 4therocker-shaft, m and hasja weight, si, snspended from its outer end. The proper shape of the cam 1T is indicated in Fig. 1. The cam j being in the' position represented in the drawings, the frietion-ro`ller Yp' should bear upon said cam at t7., in which case the bel- `lows would be closed; but in order nto show the bellows open in the drawings I have drawn the said friction-roller and the arm to which it is attached, as well as the other arms of the rockershaft wf, in the positions they are car- NOW letit be understood that the machine is in operation, and lthe friction-roller p bearing on the cam qi, as aforesaid. In such case the cam will operate on said friction-roller, and

'from side to side of the machine.

will communicate motion ,t it and the arm o', and by means of said arm 0 and the rocker-shaft m motion will also be communicated to the other arms, 'if n and r, so as to bring said arms severally into the positions in which they are represented in the drawings. The bottom board. t', of the bellows will follow by its own gravity and descend with the arms n7 nl until said bellows is fully open. About this time the mo'st prominent part of the cam q1 will pass 'in contact with thesaid friction-roller pT and leave said roller free to descend. This bei ugeffected, the weight .s7 will draw'downthe arm ri, and by means of the said rocker-shaft mT and the arms if nT will will force np the bottom board, ti, and close the through the slits or holes through the top thereof. The airin passing up through holes made. through the frisket will impinge against the sheet and elevate it suiliciently to allow of its being taken. hold of bythe delivering. rollers, as above named."-- By turning the cam q around on its shaft i, either one way or the other, and to such extent asthe case may require, and afterward securing the same by means of a set-screw to the shaft, the periodv of blowing the bellows may be regulated so as to cause the current or currents of air from it to strike against the sheet of paper at the proper time and place. The said deliveringrollers may be constructed and he made to operate as follows:

u el, Figs. 1, 7, and 26, (the latter figure bei ing an end view' of the system'of rollers now to be described,) denote two rollers extending The said rollers have a series of endless bands or tapes (one ofwhich is seen at fw', Figs. 1 and 2) running over them in t-he grooves a .'zf, &c., Figs 7o I e y z', Figs. 1 and 4, denote two other similar rollers,` which have anoth erand corresponding seriesofend'lessbands,a, runningaround them, and certain grooved pulleys, b'3 bi, 8:0., Figs. 1 and 7, which pulleys are placed on the transverse shaft c. The number of bands may be ymore or less, according to the sizeof the sheets the machine may be intended to print. The rollers uT @land their b a'nds may be regarded as one set,`and the rollers 3f z', with their bands, may be regarded as another setof said rollers and bands. The said sets of rollers are arranged in and sustained by a frame, di, as seen in Figs 1, T, and 26; The said frame is supported by two of its corneis on the top rails of the press-frame. -Its other two corners are supported by pivots en c in bearings which ad- I mit-of the frame and its rollers being raised up into a vertical position, as vseehin Figs.' v 7 and 26, in order to make room to remove t-he platen from its position directly over the types.

The pivots of the v -the machine to'be in $0 on said rocker-shaft, by which the shan c run in bearings h* It", affixed tothe top edges of the sidek pieces oi' the frame of the machine, as seen in Figs. .2 and 3. These bearings vshould be made adjustable. The said delivering pulleysfrollcrs, and bands aredriven or putin motion by means of an endless band, which runs over the pulley L on the y-wheel shaft, and the pulley l on thc shaft e. By means of a propel-proportion between the diameters of the pulleys k l any desirable speed may be given to the delivering rollers and bands, so as to quickly present thesheets .to the action 'of theily, to be hereinafter described, without interfering with the action of any-other part ofI the machine. l

The operation of the delivering rollers and pulleys'and bands is as follows: Snpposing be carrying a sheet out frombetween the bed and platen, and that ,suchv sheet has arrived at the proper place for it vto be elevated by the bellows, as before described, the moment said sheet is so elevated the ,forward movement of. the frisket will cause the sheet to enter between the aforesaid -two sets of rollers and bands, which rollers and hands,

as wellas the pulleys on the in motion,will

quickly'diaw said sheet from the i'risket and present it to the action of the ily m", Figs. 1 and 27 ,f whose construction and operation is as follows: Fig. 27 denotes a top .view of said iiy m,v including the rocker-shaft` n, to which said fly is attached, the spring os fly is successively t-hrownover to lay the sheets on the pile, and the toothed wheel or pinion p, by means of which the fly is brought back to the proper position for receiving the sheets'from th delivering-rollers. 'Said y is composed of the arm or stock g", Figs. 1 and 27, and a series of lingers or prongs, r"- i, Sie., which project from said stock, a'sseen in Figs. land 27. Every lsucceeding pair osaid fingers except the two outer should be cc vered with lightv cloth or .other suitable material, as seen in Fig. 27, so as to form a species of web from one finger to the other. The object of this is to enable the air toact against said webs when' and modify or retard `the fly is putin motion, the velocity which it would otherwise receive. A friction-swing. a. Fig. 27, is made to cooperate in the same object. Thisit does when the ily is thrown over by sliding along against a sortof curved and stationary cam or inclined plane, t', attached to the frame of the press, as shown by the dotted lines in Fig. 7. XVhen the ily is in its proper position for receiving the sheets, as shown in Fig. 1 and by the dotted lines-in Fig'. 7, the several endless bands of the lower set of rollers and pulleys y cnt-er the spaces u u, &c., between the lingers. The rocker-shaft n", to which the fly is att-ached,` is Sustained in bearings on the top of the front side of the machine.' The winding, or,as it is sometimes called, spiral spring o on the rocker-shalt n is secured to said shaftby means of the collar fr and the setaction, and the t'risket shaft es, being f said lever is seen at d',-

of sheets. The, said ily-cam screw v". By means of said collar and setsecured in any place which may be necessary t-o .adj ust o'r tem per the force of the spring to screw the former may be turned around and thc labor it may have to perform in successively throwing over the sheets on the pile. spring u is secured to the press-frame by inscrting it in a hole made inthe side oi' the collar .'L, 'which collar is held fastr by means ot' the pin y", which projects from it, and is made to enter a hole made in the side of the bearing for the journal of the said rockershaft. The ily sl.ould be capable of swinging through an lare of one hundred and eighty degrees, more or less, as circnmstances'may require. The rotating cam z", Figs. -1 and 7, operates the vertical lever a9, which in its turn moves the horizontal slide and rack b. Said slide-rack gears into and turns the pinion p, and consequently the rocker-shaft and tly, to which said pinion is attached, the same being done in such manner as to carry said fly over and into ythe position it must occupy in order-to receive a printed sheet of paper from the delivering rollers and pulleys here inbefore described.

the ily in order to 4lay 'lhe other end of said c', Fig. 7, denotes a connecting-rod, which the top end of the by proper joints connects levera to the slide-rack b 4The fulcrum of Fig. 7. Said fulcrum may be aixedto a bracket, which may be bolted to any convenient part of the end piece of the press-frame. It is best that this fulcrum be made capable of proper adjustment. 0n the lower end of the levera a friction-roller, e", is placed, it being for the cam z to operate against. The part of the motion to the leverl is seen at f s. The part g is used to hold the ily still the proper length of time for the reception of the sheets from the deliveringrollers. The. part h is quick turn or falling off in said cam calculated to leave the lever a free from the action of the said cani at the instant and'during the time necessary for the action of the spring o when it throws the tlyupward and over upon the pile should be made adjustable by being so fitted on the hub ofthe cam q as to be easilyturned round upon it, -either one way or the other, as the case may require. lt may be secured in place vby a shall be hung screw. I n caseA the ily-frame upon the front side of thepress, as above decam which gives scribed, the table for the reception of the pile of printed sheets as they may be delivered from the machine by the said y must be placed at the right hand and nearby the person who may point the sheets on tympan.

The operation of thefly is as follows: Supposing the machine to be in action', and theiiy to be in the required position for the reception of a sheet from the delivering-rollers, and said sheet to be on its way through the said delivering-rollers, and that it is being carried on the bands over the fingers of the fly, the moment its forward edge reaches the 'upper and to the required position said fly.

' or its friction-roller e free to move down the part h of said cam. The spring 0* will then immediately throw t-he fly, with the sheet upon it, over updn the table or heap where'on said sheet will he deposited. have been thns delivered on t-he heap, the action ofthe cam on the friction-roller e? will cause the iiy to move back in proper season to receive the next sheet from the said delivering-rollers as it may pass through them, as hereinbefore described. In moderate-sized printingmachines it isl best'that the sheets should be laid o' at the front side of the machine, as above described; but in t-he case of very large machines it may be desirable to deliver the sheets' at the right-hand end of the machine. In snchlcase the fly and the machinery to operate it may be modified as follows, towit:

v- Having' thus detached manner, I will now explain the conjoined operations of the several parts when in combination with-,each other and for the performance of -the usnal'process of printing.

'ofgiving the' impressions'.

Figea described'my machine in a frame into nearly vertical posit-ions, iu which I they maybe secured by means'of suitable coutrivances provided for the purpose. The pllaten is next to be moved away-froi`n over tie frame arev to be removed, sotli'at the form. of types may be conveniently pntand secnredin its place upon the bed in the' usual way. Then the. frisket hasbeen properly covered andtted to the form, as before delscribed, it andthe nipper-frame maybe put in theirplaces, care being taken that a Set of nippers of the proper length for the width of sheet tobe printed be adapted to the said frame. back to its place over the form of types, and the tympan .and roller-frame may be turned down to their proper positions. The points.

must next be attended to and adjusted to theirproper places for producing register, by means ofthe apparatus for the purpose beforedescribed. .1 This is `nest done by experiment, as is usual in other printing-presses. Afterthese things have been properly attended to, let.the

paper,-snitably prepared to be printed. be laid upon the tablc'providedto receive it. T he person whose duty it is' 'to point 'the sheets having placed pue foot upon the lever to pre vent impressions' from being produced, the machine may be started or putin motion. If the inking-'rollers' are Vfree from ink when the machine isathus put in action, it will be nee- 'essary t0' xuri'thej machine awhile without pro# dncing. any are properly covered 'with ink` A sheet may be pointed, and ldirectly afterward the foot must be removed from the lever, in order that themachine may commence its operation Allparts of the machine being now -in operation together, in

the manner before described of the'severah parts separately, and 'the inking-rollersliaving rolled over the forifof types and covered the faces with ink, the nippers will next ad.-l vance and seize the sheet-ofpaper on the tympan or feed-board,- as before described. The

.frisket-carriage will next be moved (by its alternator, as before described) towardthe `lefthand end of the machine. Thiswill carry the cam i against the stud k* and press' back the' spring hsrand thereby disengage the arm of the lever e, which will cause the points to be disengaged from the sheet., The nippers will then immediately be made to draw said sheet 'from the tympan. Said sheet, as it .slides from said tympan and as the frisketis carried along under it, drops down upon the frisket, as hereiribefore described. flh'us .the sheet will be introduced between the platen and the forni of types, and 'when the motion of the frisket-carriage is arrested the sheet will haver vbeen brought into a proper position to receive an impression.` Alittle before thisfhappens, the bed (by mans of the alternator, as aforesaid) will begin to rise, and immediately after said sheet has become stationary will be forced up by the continued action of said alternator bed. Next the frisket and the nipperv The platen may next be moved impression, or until the' rollers joints, or any andother parts of the mechanism u ntil the form of typesis carried in contact with the said sheet and against the platen with suiiicient force to produce 'animpression The said alternator `willthen be drawn back by the crank f which will canse the bed to descend to the position .inA

which it rests while the types are being inked. The frisket-carriage will next again move toward the right and again carry the inkingrollers over the for m` and the nippers toward the tympan, and the frisket, having the sheet upon it, out from between thebed and platen a and under the feed-board until .the right-hand edge of said sheet arrives over the sli-ts or holes This being done, the cam g will allow the operatedas aforesaid and Vcauseone or more switcurrentsof air to impnge through-the frisket against -t-he sheet of paper and elevate the edge of said sheet, which, continuing to advance by the movement of the frisket', will be quickly seized by the delivering-rollers and carried o'ver the ily, which at the proper mo2 ment will be thrown over` so as to deliver saidsheet onthe pile, as above described..l In the meantime another sheet will have been pointed and taken by the nippers into the press, said nippers being made to grasp the said sheet about the time that the sheet previously printed enters between the delivering-rollers. The delivering apparatus is thus made to deliver one sheet while another is being carried into.

the press and printed. Thetympan-sheet is most needed when the second side of the sheet of paper is print-ed; but it should also be used when printing the first-side thereof..

All-parts of the above-described machine are capable of modification, and equivalents well known to mechanics may be substituted for almost any oneor more of them; but as Iam persuaded that su'ch modifications or substif tutions as may under any circumstances be of any advantage will be readily made by mechanics skilled in the business of press-mak-j ing, I refrain from further explanation of the Same.

Having thus'specited my improvements, I shall now proceed to point out thenature andextent of my claims.

I claim- 1. The mechanical combination by which the motion produced by the `crank and pitman is so modified and communicated to the'y togglejoints as to produce the impressions, and so as to gveto said toggle-joints the necessary intervals of rest and reciprocating motion, the same consisting of the alternator q anda connecting-rod or pitman, wi, in combination with said crank f, Fig. 7, and said toggleother mechanical equivalents, acting substantially as specified, the said toggles having a roller, r", or any mechanical substitute therefor.

2."The mechanical combinationv employed 'to operate the frisket-carriage or impart to it with. the inking-rollers and nippers, their peculiar intervals of rest and reciprocating mo- `froth the form of types.

9er-fx tionstoward and from described, the same consisting, first, of the alternator g2; second, the lever or arm charms wf, their rocking shaft' 2', and roller i, connectedwith the alternator andfrisketlcarriage; third, the rocking shaft c, arm d", connectingrod e, and the crank h, or any mechanical equivalent or'equi-valents therefor, the whole being made, arranged, and operated togethersubstantially in the manner as hereinbet'ore specified.

3. In combination with the alternator .g5 and pitman u, the slide d, operatedby the treadle in the manner substantially as described, where by the pressman at any time while thesaid alf ternator is in motion is enabled to vprevent it from being thrown or moved 'against the tog gles l(or roll thereof) su'iciently to straighten or move the said toggles' into line with each other, `and thereby produce an impressioni 4f The combination of mechanism (or an @equivalent or equivalents) by which the nip' 1 pers (seen in Fig.

consisting of the'rod s andy its. arm a-, the-' springs t, the catches ua and o', and thegrooves b3 and the sto s'c d, and the vrotating lcam l) are operated, the 'same named in the escription.'

5 The combination of the said ni ppers with frisket-carriage, operated as above set' forth, the same being for the purposes and construct:-

ved substantially as aforesaid. Y

. 6. The mechanical combination (or'an equivalent' or equivalents) constituting .the' means for j making or obtaining register, the same consisting ofthe movable'stocks, the points n, and the levers o", w", and e, and mechanism consisting of the cams i and gi and thes'pring h, which operate them, the same-being applied and constructed and. operating'substantially as hereinbefore described.

7. The manner above described of changing the position ofthe register-poitsso as' t'o range with each other across the feed-board and the sheet 'either inbnedirection or the other, in

order to enable the pressman to turn the sheet all as set forth;

The method above'described of securing greater certainty of accurate registerf-that is to say, causing the nippersjto rest from their and printits second sde'in another direction,

horizontal motionforfrom that motion by..4

which they are'` carried toward the sheets of paper) while they are being closed on the said sheets of paper', and while the carriage or part from which they receive said motion continues its movement, substantially in the manner set forth'.

9. The above-described manner of construct-v ing the nippers-that is. to say, the upper blades somewhat longer than the lower blades thereof, wh'erebythe said upperr t blades are made to project beyond the said lower blades, in o rder that they, the said upper blades, may beA pressed down upon the edge of the sheet of 4paper on the tympanor feed-board, so as toA hold the p aper 'still therethe form of types, as

the making'.-

14V llje on while. the" said lower blades .are vbeing brought up to secure said paper in thenippers-, the same being of importance for the se-v curity of good register. A

10. For theadditionalsecurity of good reg' ister, withdrawing the register-points from the paper after it has been seized b y the n ippers, but previously to its being started from the place in which it has been adj usted or pointed,

the same being necessary tosecuregood registcr and prevent any enlargement ofthe pointholes ontearing of the paper at the point-holes made through it;

` 11. Altering the widtlxof the tympan to make it correspond with sheets' of various widths or nippers of various length, while the register-points inthe meantime are'still preserved in their central position.

12. The delivering-bands w7 and a",.and also the dcliveringrollers 1, ei, 1 7, and loperating 14. 'Ifhe delivering iiy-frame or its equivalent, in combination with the delivering,

bands wT and a", and also with the delivering rollers' u?, r11 j, and `z, and also with the shaft e and the pulleys bs b brb", Sac., operating substantiallyns aforesaid, or any equivalent or'equivalents for either or all of them.`

15. The employment of the fly or its equivaient' for receiving and piling the sheets.

16. The arranging and operating the flyframe inv sneh manner that its motions may beinl directions perpendicular, or thereabon't, tothe side of the press, the same enabling me to deposit the imprinted paperin a heap close to or directly by thc lside, of the pressman, and thus afford him the opportunity of' morel readily'examining each sheet after it isprnted than he would enjoy if the fly-frame op-,

erated in any other direction. 17. The manner setl forth of operating the nippers, and which is also exhibited in. Figs.

11, 14, 15, 16, 17,18,1920, 21, 22, and 23, and hercinbefore described;

. 18. The combination constituting the mechl:mism employed vto conv'y the printed sheets from'the deliveringrollers and bands l(or an equivalent) 'to the pile or table provided to receive them, the same consisting, iirst, of thev delivering iiy-frame' or asnbstitute operating 'substantiallythe same; second, the mechanism (or a substitute therefor operating.substantially the same) employed to givesaidyits proper motions and intervals of rest, the same consisting of the cam z, the lever a,. the rack b", the pinionl p?,

Vand the spring 0; and, third, the devices (or substitutes operating' substantially the saine) employedfor the adjustment and government of the motions of said'y,vand its intervals of rest with respect to extent andtime, thesame being done by making the cam z, the spring o8, and the fulcrum of the levera. adjustable. f

- 19. 'The manner of constructing rand arranging the delivering iiy-frameby which it may r'be depressed below thej bands, rollers, and

pulleys, by means of which the sheets of pa`l per are successively presented tothe action of the said ily in such manner that saidily shall not itself obstruct its reception of the said sheets preparatory to delivering them on the pile. I

20. Thedetached or independent manner of arranging the delivering-bands, pulleys, and ro1lersby which I am enabled to give any required velocity to them or any of them, and in that way to govern the time of the final delivery of the sheets successively with reference 'to the times'of action of other parts :of the machine,` and thus to gain a saving lot time which could not be gai ned were the velocities of said bands, rollers, and pulleys ar! bitrarily governed by the motion ofthe frisket or frisket-carriage,or any other part of. aats. surface press, or by the velocity of the cylinder or any other part ot' acy-lindespress, the same beingdone by altering the relative dip ameters of the pulleys'k and l", or any equivalentmethod.

V21. The constructing one orlmore of the distribution-cylinders so as to make it capable of lreceiving and containing steam orhot Y or cold water, by which its temperature, .as

well as that of the ink upon it, and which is to be imparted to the rollers, may be governed. In witness whereof I have hereto set my signatn re. v
