IMPROVEMENT IN LOCOMOTIVE CYLINDER PRlNTlNG-PRESSES.

Specification forming part of Letters Patent No. 1,775, dated September 10, 1840.

To all whom it may concern:

Be it known that we, CHARLES JOHN CARR and ANDREW SMITH, engineers, both of Bel traveling or locomotive printingcylinders as they pass or roll over the forms of type in their passage from one end of the machine to the other, the forms of type being placed on fixed tables; and it consists in certain novel features, additions to, or improvements on or in such printing-machines.

These novel features consist, first, in the arrangement and construction of those parts of thxmachine nsed'for receiving the sheets of paper from the delivering-tables and giving them to the printing-cylinder-aud guide tapes or bands, to be conducted through the machine and printed upon, and afterward delivering the printed sheets from the machine, the guide-tapes and printing-cylinder formingno part of theseimprovements; secondly, in anim proved apparatus for distributing the ink 'taken'from the inking-troughs and doctorrollers and passing it onto the inking-rollers to be conveyed to and spread over the form of type from which'the impression is intended to be taken; thirdly, in the arrangement and construction of certain parts suit-able for efiecting a register, as on booksor such other work where it maybe found necessary or desirable; and in order that our invention may be the better understood We have appended several drawings and a description of one modification of the above class of machines with our improvements applied thereto, and shall describe the operation of .such machine in conjunction with the operations of our improved or additional parts thereon.

Figure l is a side View; Fig. 2, a plan view;

Fig. 3, a transverse section taken on the line a b, Fig. 1; and Fig.4 is a longitudinal section.

A A is the frame-work of the machine, upon the upper part of which the printing-cylinder B travels, it being guided in its motion by a V-shaped strip a a along the bed on the top of one of the side frames anda correspondingly,\sha ped groove a formed-round one end of the cylinder, as shown in Fig. 2. Upon the ends of the cylinder toothed wheels or: rims C C are plac ed,which take into toothed racks D D, on the top part ofthe frame-work.

' EE*are the several inking-rollers to give the proper supply of ink to the' form oftypeand F F* the distributing-rollers, all of which are mountedin the traversing frame G G, said frame being suspended from the axle of the printing-cylinder B. This frame causes these rollers to travel overt-he distributing-beds and forms of type as the printing-cylinder moves forward and backward. The frame-G is kept in its proper position by means of small rollers a a, Fig. 1, aifixed to it, running against the under side of the toothed rack D.

H, Figs. 3 and 4, is the table upon which the form of type is placed, and is adjustable by means of screws or in any other convenient manner.

I I are. the guide-tapes which conduct the sheets of paper to the cylinder and under it to be printed uponand afterward deliver it from the machine, which tapes or bands pass over the receiving-rollers hereinafter mentioned and round under the printing-cylinner, their ends being aflixed to rollers mounted upon cross-rodsaffixed to the framing which carries the delivering-table.

K K* are two stationary delivery tables, which are placed at each end of the machine,

and are supported on arms L L*, extending from the adjustable pieces M M*, Fig. "l, which slide in dovetailed grooves N N* in the side frames A A, so as to allow thetables to be brought nearer to orfarther from each other, asthe extent of traveling motion in the printing-cylinder is required to be increased or diminished, according to the size of'thev sheet of paper to be printed upon,and may be fixed in their proper position by means of screws or otherwise; or the delivering-tables may be made adjustable in any other convenient manner.

O is the winch-handle by whichthe rotatory motion is given to the cylinderv and by which it is caused to travel along the machine, the toothed wheel 0 C taking into the racksD D, affixed to the side frames of the machine; or the cylinder may be moved backward and forward without this winch by a handle projecting from the sliding frame G G, by which the person attending the machine can push or pull the frame, and with it the printingcylinder, forward and backward, the racks and wheels giving it the required rotatory motion.

Having now described the general features of the machine to which our improvements are applied,we proceed to describe the first.

portion of our invention, viz: the arrangement and construction of mechanism by which we effect the transferring of the sheets of paper to be printed upon from the delivering table to the conducting-tapes, which convey them round under the printing-cylinder passing over the form of type.

a a are two lovers connected by rods 0 c and turning on bars I) b*, mounted in the sliding frame G G.

d (1* are two rollers mounted upon the upper ends of the levers a of, around which rollers the tapes for conducting the paper to be printed upon pass.

e e* are two tail-pieces forming the lower ends of the vibrating levers a, 00*, which, as the cylinder travels backward andforward in the machine, come alternately in contact with their respective stop-pieces ff*, afiixed to the adjustable sliding pieces M M* of the delivering-tables K K*.

g 9* are leaves or lips, of metal or wood, forming a continuation of the delivering-table K K*, and turn on centers in the frame work L L* at h W.

Z V, Fig. 4, are springs for keeping them elevated when receiving their supply of paper.

1' 'i* are strips of wood acting as guides atfixed to the upper sides of the lips or leaves g g* and are hollowed out on their under side, leaving a channel for the passage of the sheet of paper to be printed upon.

is 70* are curved tail-pieces attached to the axis of thelips or leaves 9 9*, against which the tappets z 2*, affixed to the sliding frame G G, strike when the frame and printing-cyh inder move to the one or other end of the machine.

' m 'm,* are adjustable gages or stops connected with the delivering-table and projecting beyond the lips or leaves 9 g*.

The distributing-table and its appurtenances,,constituting the second feature of our present invention, is seen best at Figs. 3, 4, and 5, this last being a detached plan View of the same shown in connection with a portion of the machine.

"12/ 'a* are the distributingtables resting upon sliding frames 00 0 0* 0* 0*, which are allowed to move lengthwise of the machine upon the stationary ledges p p and 19*10 o the frame-work of the machine. ,4 q q q q 1* q* q* are pins affixed to the previous contact of the parts.

under side of the distributing-table, acting against the inner edges of the sliding framework 0 0 0 0* 0* 0*.

r 7 are cranks, the pins of which take into the distributing-tables n of. These cranks are 'mounted'upon the upright shafts s 8*, turning in suitable bearings, and carry upon them the ratchet-wheels i i (Seen in Fig. 3.)

u u is a rod which has an alternating motion given to it by means of the tappet 'r, mounted .on the movable frame G, striking against the adjustable stop-pieces '10 20*.

a: x are levers mounted and turning loosely upon the crank-shafts s 8*, and are connected at their ends to the alternating-rod u it, which levers carry the clicks or pawls y y*, Fig. 3, taking into and driving the ratch et-wheelst t The action of the whole is as follows: The person attending the machine turns the winchhandle round (say in the direction of the black arrow,Figs. 1 and 4) until the printing-cylinder has arrived very near one of the deliveringtables. The receiving-roller (1 will then be in the position shown bestin Figs. 1 and lthat is, with the tapes or bands pressed by it against the printing-cylinden' The sheet of paper to be printed upon has at this time been placed upon the delivering-table K, passed through the guide 1', and its edge brought against the stationary gage orstop-piece m. On the cylinder continuing to move a little farther the tail-piece e of the lever a arrives in contact with the adj nstable stop-piece f, by which means the receiving-roller d is carried away from the printing-cylinder, which, by means of the connecting-rod 0, brings the other receiving-roller (1* with it toward the cylinder. During this operation the tappet e on the movable frame G is brought against the tailpiece 70 of the lip g, by which means the sheet of paper is carried downward to the periphery of the printing-cylinder, and is there held by the further descent of the receiving-roller (1* and conducting-tapes I I, as shown in the detached view, Fig. 6. During these operations the tappet r, affixed to the movable frame G, has struck against the adjustable stop-piece w, and by so doing has forced the alternating rod to and lever to in the direction of its arrow, thereby turning the crank-shaft s, by means of the pawl y taking into the ratchet-wheel t, round a portion of a revolution, and with it the distributing-table 'n n, which, being pro-- pelled by the crank, has, by means of the pins q q, working in parallel guides of the slideframe 00, a tendency to i move in the direction of the arrow, Fig. 5, while the sliding frame 0 0, being free to recede, gives way to the pressure exerted against it and permits the table to move simultaneously at right angles to its other motion, thereby changing every point of contact between it and the distributing-roller F, which took place at the The supply of ink to the distributing-1 ier Fis given in the following manner: R R*, 'Eigswi, 5, and 6, are the ink-troughs, which are mounted uponthe frames L L*, and are consequently adjustable with them to suit a varied extent of motion in the machine in order to print upon sheets of paper of various sizes. P 1 are antifr-iction rollers mounted on pins aifixed'to' arms Q Q*,' which turn loosely upon the axles of the ductor-rollers S S*, on which axles are affixed ratchet-wheels acted upon by pawls afiixed to the arms Q Q, as shown at 0. Fig. 5. When the frame G moves to the one or other end of the machinesay in the direction of the black arrow-the anti-friction roller P will run up its inclined ends, and by so doing will raise the arm Q,a'nd by means of the pawl taking into theratchet on the axle of the ductor-roller will turn it round 'a portion of a revolution, and by so doing adord a fresh portion of its surface and supply of ink .to the distributing roller F. When the frame G is'moved in the reverse direction,the arm Q, with its roller, will again fall, ready to be acted onin a similar manner on the return of the carriage. The parts then being situated as shown in'Fig. ti -that is to say, thesh'ee't of paper having been'brought by means of the'lip g and guide 11 down onto the cylinder and it being there'held by the receivi'ng-rod df and guide-tapes I I-the Winchhandle isturned in the direction of the red arrow, Fig. 6, by which v means the cylinder is made to revolve back again, carrying with it the sheet of .paper and passing over the form of type-on the table H, where it receives the required impression; which is produced by the weight of the frame G G. and the cylinde'r as it rolls over the form of type, and as the cylinder continues to revolve toward the delivering-table K* at the left-hand end of the machine the sheet of paper now printed upon is carried or conducted out from the'cylinder between the roller (1 and the printing-cyli'n der, from whence it is taken away by hand. At the same time the tail-piece e" of the vibrating lever a* meets with the stop-piece f*, when the sheet of paper having been laid upon the delivering-table K*, as before described, it is embraced between the receivingroller d and printing-cylinder B, The tappet "a has also struck against the stop-piece 10*, thereby bringing it back into the position shown in Figs-1 and 4 and shifting the distributing-table n*, as before described with reference to the opposite side of the machine, the feed of ink for the next sheet to be printed upon being given by means of the roller .P*, as at the other end of the machine, when, the winch-handle being turned again 'the'reverse way, the sheet of paper is taken through the machine, printed upon as before, and delivered out at the right-hand end, and so on, the cylinder producing an impression at each forward and backward motion of-the machine, receiving the sheets alternately on one sideof the cylinder and delivering them at the other. Should any extraordinary I pressure be required, the-anti-friction rollers Eson the frames G G might be tightened upon the under side oi the racks D D, by which they would be made to hold down the cylinder upon the ype, and thereby produce a greater pressure thanis caused by the weight.

Should it be required to use thismachine for printing singly or in only one wayin which the cylinder revolves, the parts drawn in red in Fig. 4 show how we efiectthis. 11 are arms supporting the table whichcarries the form of type. together by the rod 2 2. 3 3 is aconnectingrod turnihg at one end on a pin affixed to the alternating bar. u. u, the other end embracing byineans of a slot a stud affixed to the rod 2. In the position shown in the drawings,

Fig. 4, the form of type is raised and *the cylinder printing while traveling in the direction of the black arrow. 'As the frameG proceeds, thetappet U will, as before described, arrive in contact with the stop-piece w, the'r'eby carryingv the bar u 1 along with it. By these means'the end of the slot in the rod 3 will arrive in cont-act with the stud upon the rod 22,- which will also be carried with it,

turning the supporting-arms 1 1 upon their centers and llowing the form of type to fall down, permit ing the cylinder to return without being in contact with the form of type, and 'in so returning the other end of the slot in the a rm.3 3 will strike against the stud on the rod 2 and again bring the form of type into its elevated position, ready to give another impression.

Our third improvement-win, the arrangement and construction of certain parts suitable for eifecting a register for book or other Work-is shown in the detached views, Figs. 7, 8, and 9, Fig. 7 being a transverse section taken 'verticallythrough a portion of one end of the machine with these improvements applied' to its delivering-table, and Fig. 8 is a plan view of the same. K K is the deliveringtable; g, the falling lip orleaf; m m, the adjustable gages or stops. It will be seen by reference to .Fig. 8 that the delivering-table is in this instance provided with slots or gates aa 01., extending in the direction of the length of the machine. I) b are springs pres sing at one end against the lip or leaf g and mounted at the other on the cross-bar c, and are capa-- ble of being moved to a'ndfro thereon and .fastened in any required situation by means of screws or otherwise. d d are the register- 'pins,.whi'ch are mounted upon the springs b b.

These pins move in slots formed lengthwise in the springs, as shown in the detached plan view, Fig: 9, so that, together with this last adj nstment and that which they are capable of receiving by means of the spring moving on the bar 0, can be arranged in any required position forwardor backward or to the right or left that the slots a. awill. permit. The

tables are made with sliding panels, so as tomove sidewise should it be required to fix the points (1 d in any situation between the slots at a.

These armsare connected The operation of the parts is as follows: The points or pins d d havingbeen removed from the springs 11 b by unscrewing the nuts e e, by which they are fastened thereto, the form oftypeis to be provided with points placed in any convenient position, as in the ordinary mode of working in register, and oneside of the paper intended to be printed upon worked off by the operation of the machine, as before described, by which means the points in the form of type will be forced through the sheets of paper, leaving holes therein, as is well understood by all printers. The whole of the required quantity of paper having been printed upon on the one side, the form of type is to be changed in the ordinary manner and the pointsor register-pins d dzaflixed to the spring I) b, as shown in Figs. 7, 8, and 9. The sheets of paper now to'be printed upon the other side are placed upon the deliveringtable K K, with the-points or pins cl 01- projecting through the holes formed by the points of the form of type. used for printing the first side, the points or pins (1 01 being adjusted in their proper position to insure the correct register by means of the slots formed in the table K and springs 12 be The parts being in the position shown in Figs. 7 and 8, with the sheet of paper laid upon the delivering-table, as already described, the lip or leaf g will on the printing-cylinder advancing toward the right hand be depressed and carry with it the sheet of paper onto the periphery of the printin g-cylinder, to be embraced by the receivingroller (2*, as described with reference to the general operation of the machine, and in so doing will carry with itthe springs b b, and consequently the points or pins dd, thereby liberating the sheet'of paper to 'be carried round the cylinder and over theform of type to be pri'ntedupon, as already explained.

The parts of novelty which we claim assecure'd to us are-- p I 1. The arrangement and construction of those parts of the machine used for receiving the paper from the delivery table or tables and giving them to the printing-cylinder and guide tapes orbands to be conducted through the machine and printed upon and afterward delivering the printed sheets from the machine, said arrangement and construction consisting principally of the falling leaf g and stop m, in combination with the receivingroller d, the whole being constructed and operatingas set forth.

2. The improved'apparatus, as above 1escribed, for distributing the ink taken from the inking-troughs and ductor-rollers, said apparatus consisting of the ratcheta on the ductor-rollers and their appurtenances, arranged and operating as herein set forth.

3. The arrangement and construction of the parts above described for effecting a register,

as inbookor other work where such register .may be required, said arrangement consisting of the combination of the springs b bwith the falling leaf 9 for'liberating the paper from the register-points.

In witness whereof we, CHARLES JOHN CARR and ANDREW SMITH, have hereunto set our hands and seals this 1 8th day of October, 1839.
