GEORGE H. GRAHAM, OF JERSEY CITY, NEW JERSEY.

PRINTING MECHANISM.

Application filed July 8, 1912. Serial No. 708,141.

To all whom it may concern: I I

Be it known that I, GEORGE H. GRAHAM,

.a citizen of the United States, residing at Jersey City, Hudson county, and State of New Jersey, have invented a new and useful Improvement in Printing Mechanism, of which the following is a specification.

This invention relates generally to printing mechanism and particularly to that class in which the operation of printing is controlled by the presence of the article or piece of matter to be printed, but is not limited thereto.

It has for its obj ect to reduce the needful parts of such machines to the minimum, whereby simplicity and cheapness is obtained, and to thereby provide mechanism which shall require little attention and will dispense with the necessity for skilled operators.

It also has for its object to provide a portable machine which in itself shall provide means for feeding sheets or pieces of matter singly from a stack 0r bunch thereof, print, count or print and count, or otherwise handle each piece and deliver the same in an orderly collection or stack.

To these ends the improvements include, among other things, a carrier in the form of a wheel on opposite sides of which or in planes tangential to its periphery are arranged the feeding and stacking or delivery instrumentalities, and intermediate of which is mounted the printing or counting device coacting with the carrier-which forms the other part of the printing coupleto suitably print upon the sheets, cards, slips of paper or the like or to count the same in their transfer or passage one by one from the feeding to the stacking position.

The improvements also include a carrier wheel with which is combined a carrying tape or guide for confining the sheet, slip or other piece tothe'wheel so as to be carried by it in its transfer from one to the other position, whereby the mechanism is adapted to handle a practically continuous succession of sheets or articles of varying lengths in contradistinctlon to a carrier having grippers or the like adapted to take,

sheets or pieces only at definite intervals and in which the intervals must be as long as the longest sheet or piece the machine may be required to handle.

The improvements also include various Specification of Letters Patent.

The mechanism is supported by a horii carried preferably through zontal table the medium of posts A by a base B, which may rest on a bench or desk, or upon somethe main of the connective gearing are supported below the table, and those which feed, print or count and deliver the pieces handled by the machine being located above the table. 7

The mechanism consists of a carrier in the form of a wheel 70, secured to the upper end of a main spindle 71, that rotates in a bearing 72, fastened to the table A, and extending through it for adequate service. The same spindle also has. fastened to it the -main driving gear wheel 73. The periphery of the carrier is covered with a ring or strip of rubber, or other suitable material secured thereto by cement or vulcaniZe-d thereon to provide an impression, surface for coaction with the printer to be presently described, and, having also, in this embodiment of the invention, the requisite adhesive quality to aid in taking and feeding the pieces to be operated upon, as fast as they are successively presented thereto and for delivering the same.

want of space.

portion of the so v the table A; those parts which consist in At the feeding position C, to the left of the carrier, is arranged a table plate 20, supported by the table A, to provide a smooth and slightly elevated fiat surface on which the pieces to be fed by the carrier are stacked upright on their longitudinal edges alongside ofa vertically, arranged bearer or guide plate 21, that is supported in a position tangential to the surface of the carrier atithat point, so that each piece in succession' is properly'presented thereto.

Behind the guide 21 is supported a feeder in the form of a rubber or other properly covered and rotating roll 22, with a portion of its active feed or adhesive surface projecting through-an opening in the guide to engage the .piece in immediate contact therewith and cause it to move forward on the table plate for its leading end to be projected onto the carrier.

This feed roll is carried at one end of a spindle 28, supported in a suitable bearing 24, fast to the table and carrying at its other end a gear wheel 26, which through an intermediate 25, carried by a suitable stud, also secured to the table receives motion from the main driver73.

Coacting with the roll 22, is a springpressed wiper 27, arranged and adapted to permit the'feed of one piece of matter at a time to the carrier 70. The wiper 27, is a strip offlat rubberpre'ferably provided with a canvas back to prevent stretching. This wiper is adjustably held or clamped in active position, asrby a thumb screw 29, in a groove or slot formed in a holder 28, that is pivoted to permit it and the wiper to yield laterally with respect to the roll 22, to accommodate the passage of pieces of matter of varying thicknesses. The wiper-holder has an arm 12, to which is connected a spring 13 for suitable pressure of the wiper against the feed roll.

In advance of this feed stantially in line with it, is a rotating primary feed roll 14, rubber faced, and proj ecting through the guide 21, to engage and feed forward pieces of matter to the roll 22, and

' wiper 27.

This primary feed roll rotates on a stud and is driven at a slightly faster surface speed than the roll 22 by an endless belt 15; the faster surface speed being provided to quickly advance pieces that may be behind in the bunch on the plate 20.

To eliminate the personal equation of feeding, the bunch of matter in position for feeding on the plate 20 is held pressed against the primary roll 14, by a yielding feed plate 17, one end being carried by a stud 19, supported by the plate 20 and held constantly to duty by a suitable spring 30, see Figs. 5 and 6. The feed plate17, may

have an inwardly projecting tongue2, 1n

line with the feeding surface of the roll 14,

roll 22, and sub- 2 to obviate a too close contact of the sheet being fed with the said roll and with the plate.

As shown in Fig. 1 the separator wiper 27 rests against feed roll 22, which is independent of the large carrying wheel and has a surface feed slower than that of the carrying wheel. As a result when a paper letter or article comes in contact with the large carrying wheel it is forwarded at a higher rate of speed than at its start, and thus is moved faster than the second or succeeding piece of paper or article until the latter also comes in contact with the large carrying wheel. This causes an increased spacing between successive articles over and above that caused by the action of the separator wiper 27.

As soon as or shortly after the forward end of the fed sheet on the feeder roll 22 passes beyond the wiper 27, it encounters a leading tape 33, of narrow widthwise dimensions passing from a supporting roll 34, thence for a short distance around the surface of the carrier 70 past the printer to a point where it is led off by passing around another roll 85. The tape returns over a take-up or tension roll 36 back to the first roll 34. This tape by frictional contact with the carrier partakes of its surface speed and confines the sheet to the carrier and holds it sufficiently rigid to its surface to cause it to partake of its onward travel for the desired distance, whereupon the sheet is finally released or led off at the discharge or delivery point D. The carrying tape obviates the use of guides or rolls or other means for holding the vsheet to the carrier and serves in conjunction with the carrier as an ever ready means for grasping the sheet so that the time of its feed is immaterial and one'sheet may follow another in close succession irrespective of its length thereby increasing the capacity of the machine. v

The tape rolls 34, 35 are idle rolls, preferably fianged, rotating on studs extending from the table. The tension roller 36, is also an idle roll and flanged, carried by a stud projecting above the table from an arm 39,

swlnglng on a pivot 40, and pulled outwardly by a spring 41, to keep the tape always .taut and to yield sufiiciently during the passage of sheets'or other pieces of varying thickness.

The sheets or other pieces carried onward by the tape and carrier are additionally guided as well as guarded by a guide or pair of guides 31, Figs. 1, 3 and 4, extending from the feedingposition to a point close to the printing or die roller 42, a portion of-the guide being flared and a portion curved to conform to the circumference of the carrier 70.

As an addition to the feed of the sheets from the roll 22 to the bight of the tape 33 'arm 10, that is carried by a spindle 11 and carrier 70, there is provided an intermediate idler roll 81, :Fig. 1, carried by a rock arm 37 and held in yielding frictional contact with the tape 33 by a suitable spring 68. This idler roll is especially useful when sheets shorter than the distance between the roll 22 and carrier 7 0 are to be fed. I

As the sheet or other piece is being carried onward its leading edge encounters a finger 9, whose inner end very slightly projects into a peripheral groove 69, formed in the carrier between the bight of the tape with said carrier and the guide 31; the location of the tape, groove and guide being such that the leading edge of the sheet will be supported against undue buckling at the time it strikes the finger 9.

As the sheet continues its movement it rocks the finger 9 forwardly for a limited distance and untilthe edgeof the sheet and the finger, traveling in approximately the same direction but in different arcs, escape each other, whereupon the finger is free to return toward its normal position.

This forward movement of the finger, is made the instrumentality that permits timely and intermittent rotation of the printer or die for each sheet passing onward through the machine. The construction shown in the drawings resembles that shown in .Unitcd States Letters Patent No. 1,022,191, dated April 2nd, 1912, but differs therefrom in some details. a

The finger 9, is fast to the upper end of a spindle 7 supported on one end of a rock mounted in bearings in the machine table A, Fig. 3. The lower end of the spindle 11, below the table is fast to a lever 11, one end of which engages the lower end of the spindle 7, and the other onshort end bear-,

lever,

mg against a stop-pin 5, under the tension of a spring 8, tending also to hold the end of the finger 9, in sheet engaging position. The finger-spindle 7 passes through an enlarged hole in the table, has fast to its lower end an arm 4, that is connected by a link 54, with one end of a stop-lever 52; the other end of which, by a suitable spring 53, is held in position to engage a stop in the form of an antifriction roll 16, forming part of the printer spindle 45. The construction is such that when the end of-the finger 9, is rocked by the passing sheet in the direction of the arrow (1, Fig. 2, the stoplever 52, is also rocked against the pull of the spring 53, to move its end away from the roll 16, and thus release spindle 45, so that they may rotate. the roll, in rotation,

After passes beyond the stopthe spring 53, causes the return of the stop-lever against a limiting stop 18 or set-screw carried thereby, and also the return of the finger 9; but as the broad surfaceof the passing sheet is still present, the

the printer and finger yields laterally outward by reason of the rock-arm 10, against the slight or gentle pull of the spring 8. As soon, however, as the tail end of the sheet passes the finger 9, the spring 8 throws the finger inwardly to its complete normal position ready to be engaged and moved by the succeeding sheet or piece.

The printer or die 12, is carried at the upper end of the spindle 45 and splined thereto by a removable key 3, for ready removal. The spindle is mounted in suitable bearings provided by a rock-arm 46, Figs. land 3, that is mounted on a stud e17 projecting from and below the machine table A; a set screw in the rock-arm in connection with a stud, adjusts the printing position of the printer with respect to the impression surface of the carrier 70, against the pull or pressure of a suitable spring as 48. The roll 16, as in said patent, is carried by a head 49, fast to the printer spindle 45, Fig. 2, immediately above a gear wheel 50, Fig. 3, loosely mounted on the spindle and in mesh with the main driver 7 3. Below the gear wheel is a disk 51, keyed to but vertically movable on the spindle, with a suitable spring and set screw to press the disk and head frietionally against opposite sides'of the loose gear wheel 50, as in said patent, the whole forming a clutch by whichwhen thestop-lever is removed from the roll 16 by the passing sheet, the wheel 50, which during the operation of the machine is continually rotating, is allowed to impart its rotations to the spindle 15, and to theprinter or die. To obtain efiic'ient action of the clutch there is interposed an oiled feltwasher 7, between the gear wheel 50, and disk on one side, and the said wheel and the head on the other side. These felt washers and contiguous parts may be kept properly and preferably constantly oiled by any suitable means. 7

The printer 42, as shown, consists ofa roll in segmental form carrying suitable matter to be impressed on the passing sheets. This matter may be engraved directly on the surface of the roll or it may be inset therein and removable therefrom, as in the case of date and timestamps or post office and bank check indorsing dies in a manner of common knowledge in the printing art.

1 After being printed upon or otherwise having caused a rotation of the spindle 45, the sheet or other piece, still within the control of the carrier 70, and tape 33, is further guided and guarded by a guide 43, curved to correspond with the carrier and extending outward substantially tangential there to and supported by a suitable bracket 44, carried by a' de1ivery plate 55, fast to the upper sideof the table A. After leaving the tape the sheet or other piece is deflected from the carrier by a guide or guides 57,

supported by brackets 63, to and between a rubber faced roll' 56, and a spring pressed bearer 62, supported by the bracket 44, and

thence in contact with a roller 59, against a yielding guide or support 64.

The roller 56, is carried by a spindle 58 mounted in suitable bearings in the table A, and carrying a gear wheel 60, in mesh through an intermediate 61 with the main driver 73. The roller 59 may be an idler roll rotated merely by the frictional contact of the moving article passing onto the delivery plate 55, as in Fig. l; or if desired it may be driven by a belt 38, asin Fig. 7

The guide or guides 57 may terminate in an end stop or stops 67 to limit the outward travel of the sheets and keep them on the plate; and the end'stop or stops may be adjustable, as in Fig. 7, inward and outward to accommodate the size of sheet operated on.

The yielding guide or support 64 is pivotally mounted in a stud 65, projecting from the plate 55, with a suitable spring 66, tending to hold its free end toward the guide or guides 57. The sheet passing from the roller 56, and spring pressed bearer 62 in meeting the yielding guide, as indicated by the arrow 1), Fig.1, is deflected thereby inwardly toward the guide 57 whereupon when its tail end passes the bearer 62, such portion will spring outwardly as indicated by the arrow 0, thereby leavin a clear space for the entrance of the succee ing sheet. As the sheets accumulate on the delivery plate 55, the guide 64 yields laterally outward,

while still providing a suitable vertical support for said sheets. i

The printer or die 42,'may be inked by any 40' suitable means, but that shown is to be preferred. The felt or other ink receiving roller 7 5 is mounted loosely in one end of an arm 7 6 pivoted on a stud 7 7 to the table A, the opposite end carrying a thumb set screw? 8 that engages a nut 7 9 supported in a stud standing up from the table. A suitable spring 1 carried by the arm bears against the nut and allows the arm and ink roller to yield outwardly to accommodate any outward movement of the die as 'well as any irregularities in the surface ofthe die and the roller.

The operation of the improved machine will have become clear from the foregoing description. It may be stated, however, that the pieces of matter preferably in bulk lined up on their lower longitudinal edges are placed on the table plate 20 against the primary feed roll 22, between it and the yieldable feed plate 17. Motion being imparted to the main wheel or carrier 70, either by hand through'a handle 74, or by power, th primary feed roll 14 will feed the sheet or piece of matter, in contact 5 therewith, forward, projecting its leading edge between the wiper 27 and the feed roller 22, whereupon, the sheet will pass between the tape 33 and the idler roll 81 to the carrier 70, which with the tape will carry the sheet onward toward the delivery position D.

It is obvious that in lieu of, or, in addition to the printer, the finger 10, may control a counter device by which each piece of matter is counted as it passes through the machine, and in this respect it is to be understood that the printer and counter are alternative devices.

The primary feed roll 14 may be omitted and the pieces fed by direct contact with the surface of the feed roller 22. The delivery devices may beomitted and the sheets be delivered by the simple guide 57 acting as a stripper or delivery device to throw the sheets off into some suitable receptacle.

The feed roller and the carrying wheel have a coeperative relation, inasmuch as they both-act to feed or forward the articles; and the object of having the feed roller operated at a slower surface speed than the carrying wheel, is that when the article comes Within the control of the carrying wheel and co-acting tape such article will be drawn away from the next following article by being moved at greater speed, thereby increasing the space between the follow- 5 ing edge of the first article and the leading edge of the second article, in excess of the space caused by the action ofthe separating device or wiper; this insures ample space and time for the trip finger to com back into normal position to engage the front edge of the following article after each operation. Such separation of the articles is also of advantage in preventing articles from crowding on or over one another in e11- tering the stacker.
