FRANK S. WEISE, 0F BALTIMORE, MARYLAND.

PRINTING-MACHINE.

Application filed January 30, 1919.

To all whom it may. concern:

Be it known that I, FRANK S. WEISE, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Printing-Machines, of which the following is a specification.

This invention relates generally to printing machines and more particularly to an apparatus for canceling checks, bills, invoices, coupons, and similar papers.

The primary object of the invention is to provide an improved mechanism for actuat ing a type carrying device so that the type will successively engage a platen and ink pad during operation of the mechanism.

The invention further contemplates the provision of an improved mechanism for printing apparatus adapted to be associated with an adding machine whereby the printing mechanism may be actuated simultaneously when the adding machine is actuated so that the checks, bills and other papers will be successively stamped and canceled during operation of the adding machine.

Another object of the invention is to pro-.

vide a printing machine having a type carrying mechanism arranged to operate substantially vertically toward and away from its platen thereby avoiding a swinging, fanning action which tends to create gustsof wind and consequent disarrangement of the papers to be printed.

The invention further aims to provide a printing apparatus which will include a type carrying mechanism having a combined swinging and reciprocatory motion accomplished by a simple arrangement of gearing and interlocking parts all of which may be actuated by a relatively short oscillatory movement to a drive shaftso that the type or die is alternately engaged with both the platen and ink pad.

The above and additional objects are accomplished by such means as are illustrated in the preferred embodiment and in the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views, in which Figure 1 is a perspective view of the apparatus showing its application to an adding machine,

Fig. 2 is a side elevation, partly in section, showing the apparatus in inoperative position in full lines, and in operative printing position in dotted lines.

Fig. 8 -is a detail view of the operating crank.

Fig. 9 is a detail view of the ink pad actuating mechanism.

Referring to illustrated the preferred form of my invention, in which like numerals of reference indicate like or corresponding parts through out the several views, the frame of the ma chine comprises the base plate 1 and the upright side plates 2 and 3 fixed to the base plate in any preferred manner and each provided with vertical front edges 4 and in clined top edges 5 to which is secured a removable cover 6 held in position by suitable fastening screws 7 and which, together with the side plates forms a casing for protecting the mechanism mounted between the side plates 2 and 8. A suitable platen 8 is mounted upon the base plate 1.

The end of the drive shaft 9 is journaled in suitable bearings in the side walls 2 and 3 and a counter shaft 10, parallel to the drive shaft 9, also has its ends journaled in suitable bearings in the side walls. Both of these shafts extend transversely across the space between the side walls and carry the gears by which the proper motion is transmitted to the printing member or die.

Segmental gears 11 are mounted on the counter shaft 10 near the side walls 2 and 3 and are rigidly fixed to the shaft to turn therewith. The drive shaft 9 is also provided with a segmental gear 12, the teeth of which mesh with a pinion 13 on the counter shaft 10. In this manner movement is imparted to the segmental gears 11 when the drive shaft 9 is actuated. A supporting shaft 14 is mounted at the top of the frame, the ends of the shaft being journaled in suitable bearings arranged at the top of the side plates 2 and3, and guide rods 14 are suspended from the shaft 13 by having their upper ends fixed to the shaft so that the the drawings, wherein is 1 operation.

rods will readily swing as the shaft turns in its bearings. Sleeves 15 are slidably mounted otherwise secured thereto, an elongated plate or relatively wide bar 16 the ends of which are rounded as shown to advantage in Figs. 6 and 7. A series of rods 17 have their ends fixed to thebars 16 and are equally spaced apart, therods serving'as the teeth of a rack adapted to be engaged by the segmental gears 11. In this connection it should be borne in mind that an ordinary rack bar may be mounted on each member 16 if desired, 'the'rods 17 in this'case being dis pensed with. 1 i g The lower ends of the bars 16 have attached thereto the disks 18, each of which has an annular flange 19 cut out as at 20 to form a gap through which the lower end of the corresponding bar 16 is extended as shown to advantage in Figs. 6 and 7 The l wer roun e ends of the bars, extended into Ispaces embraced b the flange 19, there- ,fore, 'formthe inner edges Of t flrcuib'te' grooves 21, the purpose ,ofwhich will presently appear. The-flange 19 inv each disk, 1s

alsonotched as at '22 forming an opening which serves as an" 21 in each disk. 4

Each segmental gearll carries a'pin 23 so located on the side of' the segmental gear as to cause it to be received'in the groove 21 of the adjacent disk 18., through the entrance 22 thereof, when the mechanism is in entrance to :the groove A brace rod;24' extends between the upper ends of the members 16, A type carrying element is secured-to the rods 17 and the same consists of a plate 25 having ears 2-6 arranged in pa1rs and adapted to embrace the lowermost'of the series of-rods 17. A

space between two of the rods 17 so that the plate--25 is held rigidly in position. Parallel grooves 28 are formed'on' the bottom carries the type 30. A spring latch 31 is attached to the plate 29 and has'its hooked end 32 adapted to engage the lowermost of the rods. 17 so that the plate 29 is held against accidental or casual displacement from the plate 25 when the type is inpositi'on. v The sleeves 15 mounted upon the guide rods 14, and carrying the rods 17 and bars 16, therefore, provide a carriage, movable on the guide rods 14 for carrying the stamping or printingdevice during actuation of the mechanism. p v 4 At the rear of the base plate is a standard 33 upon which an ink pad 34 is mounted, the

latter being preferably held at an angle as shown. The ink pad 34 is of circular for- .mation and is rotatably mounted upon the stem 34 as shown to advantage in Fig. 5 of the drawing so that the ink pad may be readily turned. An annular flange is formed on the ink pad and this is provided with a series of teeth 45 on its lower surface. The drive shaft 9 is provided with a collar 46 held by a set screw 47 and this collar carries ears 4.8 through which a pivot pin 49 isvextended. Avspring pressed pawl 50 is mounted on the pin 49 and is disposed so that its end engages the teeth 45, this struc ture being shown to advantage in Figs. 3 and 9 of the drawings. When the shaft 9 is, actuated in one direction, a rotary motion will be imparted to the rotatably mounted pad. When the shaft 9 returns to normal position, however, the pawl will ride over the. teeth and therefore it will be obvious that the pad will be rotated only in one di rection. I i I One endof the drive shaft 9-is extended beyond: one of the side walls as indicated at 35 and. hasits terminal provided with a hand crank 36. A coil spring 37 has one end fixed to the shaft as indicatedat 38 and the opposite end of the spring is engaged with the side walls 30f the frame. The

spring 37 exerts a pressure on the shaft so .39 by a removable pin 36 and is fixed to a .lever 40. included in the adding machine t will be i obvious therefore, that the printing machine will be actuated upon each actuation of theadding machine lever;41. I r A V I r The crank 36 as shown to advantage in Fig.- 8, consists of two hingedly connected parts .51 and 52, the part 52liaving a flat spring fixedly connected by the fastening element while the-opposite end of the fiat spring bears against the part 51. spring is comparativelystiff so that there will be no. pivotal act-ion of the parts until some resistance, in addition to that offered by the mechanism is encountered. T he purpose of this will hereinafter appear.

Assuming that a stack ofchecks, bills, invoices, coupons or other papers is placed upon the platen S. Vhen the figures indi cated on the uppermost paper are recorded on the adding machine the operator will ac tuate the operating handle 41 whereupon the shaft 9 will be actuated through the connected members 36, 39 and 40. Approximately 9. quarter turn will thereby be given to the shaft 9 and consequently to the segmental gear 12 which by virtue of its meshing with the pinion 13, will cause the counter This shaft 10 to turn and thereby actuate the segmental gears 11. Fig. 5 clearly illustrates the engagement of the segmental gears 11 with the rods 17 and it will be apparent that the type carriage will be actuated when these gears 11 are actuated. There are as many rods 17 as there are teeth in the segmental gears 11 so that the lowermost rod 17 will engage one of the end teeth in each segmental gear 11. The gears 11 will thereby swing the lower end of the carriage forwardly and upwardly until the carriage is in vertical position above the platen. Continued movement causes the carriage to move downwardly vertically toward the platen to engage the latter or any papers placed thereon. The rods 14 swing from the shaft 13 and the carriage slides on the rods so that there is a combined swinging and vertical movement given to the carriage as it moves from the ink pad to the platen.

As soon as the operator releases the adding machine lever 41, the spring 37 will urge the shaft backwardly whereupon the parts will return through the reverse movement until the type is engaged with the ink pad. l/Vhile the parts are in the latter position the pins 23 on the segmental gears 11 are in registration with the grooves 21 as shown by dotted lines in Fig. 2. As the segmental gears 11 are swung, the pins 23 travel through the grooves 21 and the proper relative positions of the carriage andsegmental gears 11 are thereby maintained so that the rods 17 are held in mesh with the teeth on the segmental gears. movement of the mechanism causes thepins to reach the ends of the grooves 21 and the pins disengage the disks by passing out through the open ends 22 of the grooves. The carriage then continues downwardly vertically until the type engages the papers to be printed. After the pins pass out of the grooves 2-1, outward swinging movement of the carriage is prevented by virtue of its engagement with the front portion of the cover 6 as shown in Fig. 5 of the drawing.

WVhen the stack of papers is of considerable height it will be obvious that the printing plate must stop during its downward movement toward the platen. Therefore the crank 36 is constructed of the two hinged parts 5 1 and 52 as above stated so that the resistance offered by the stack of papers, while it will cause the mechanism to stop, will not prevent the continued movement of the portion 51 of the crank as shown by dotted lines in Fig. 8. Therefore, the pitman 39 may move through its full movement upon each actuation of the adding machine and the movement of the printing plate will be governed entirely by the height of the stack of papers on the platen.

It is possible, of course, to operate the Continued mechanism by applying the power directly to the counter shaft 10 and when the machine is used for ordinary printing purposes, not in conjunction with an adding machine or the like, it will be found advisable to apply the power directly to the shaft 10. By using the power shaft 9, with its crank, and the relatively large segmental gear 12, sufficient leverage is obtained whereby the limited movement of the lever 40 on the adding machine, is suflicient to actuate the crank through a quarter turn for imparting the desired movement to the mechanism. Fig. 3 shows the application of a motor 42 to the device, the motor shaft 43 being extended into a housing 44: within which a suitable connection is made with the shaft so that the latter will be actuated when the printing machine is used for ordinary printing purposes. When electricity is employed to actuate the machine, it will be obvious that other electrical devices, such as solenoid, induction coils or the like, may be employed to actuate the power shaft.

The motion of the carriage, it will be observed is a combined swinging and reciprocating movement which causes the type plate to move from the elevated angularly disposed ink pad outwardly and vertically downwardly toward the platen. The swinging fan like motion, commonly employed on some check canceling devices, therefore, is avoided and consequently no gusts of wind will be created nor will a shifting of the papers take place and the papers, arranged in a stack on the platen, will not be disarranged and the machine may be rapidly operated while no device for holding the stacks of papers is required.

The base plate 1 is hingedly mounted by means of the hinge 5A to the rear edge of the adding machine shelf. By this construction it is possible, after removing the removable pin 36 to swing the entire device off the shelf and permit the same to hang down below the shelf at the rear thereof so i, that the shelf may be entirely clear when it is not desired to use the printing appa ratus. Removable fastening elements 55, attached to the front edge of the base plate, and extending through convenient openings in the shelf of the adding machine are em.- ployed to maintain the apparatus in firm position on the shelf when the apparatus is 1n use.

The vertical movement of the type prevents the tendency of the stack of checks to shift and topple and also prevents blurring when the checks are printed. Furthermore, the position of the platen in front of the mechanism permits the checks to be in sight of the operator at all times. The inking pad protected by the cover and successively engaged by the type will prevent excessive ink being supplied to. the type and consequently the printed impression will not be unduly wet.

t should be pointed out that the machine is adapted to be connected up in series by placing several of the machines side by side, or front to back and having the shafts 9 extended agid coupled together so that all of the machines in the series will simultaneously operate. This will be found useful in post-offices, banks and mercantile establishments where large quantities of papers are tobe canceled. A sheet or a stack of sheets may be placed on each machine and therefore several papers may be canceled at the same time. I

The platen 8 is preferably slidably mounted in a dovetailed groove 56 and its marginal edges are shaped to fit in the groove so that lateral sliding movement of the platen on the plate 1 is permitted. A finger depression 57 in the platen permits the operator to slide the plate. This will permit the checks to be shifted so that the canceling stamp may be applied to any part of the surface, as it will be understood that the checks will be received at the bank with one or more prior cancellations and 'it is desirable that the cancellation mar s be separate and legible. The checks may be readily shifted when in a stack by merely moving the platen.

The foregoing description and accompanying drawings have reference to What might be considered to be the approved or preferred form of my invention; I desire it to be understood that I may make such and slidably mounted, and means mounted on the shaft and on the said carriage to transmit swinging and sliding movement to the carriage when the said shaft is actuated.
