Y corresponding to the number of letters in the l The preferred form of my invention is alphabet so that by adjustment of the three illustrated in the `accompanying drawings, discs shown in the present case, relative to inwhich one another, any desired combination of im,

5 Figure l shows a vertioalsection through three' letters may be established. Each of the three discs is formed with an annular series of perforations 10 and these perforations are arranged in such a manner that when three letters on the three discs are brought into proper alignment the perforations of the three discs will also be aligned so that the three discs may be firmly held in adjustedv positionrelative to one another by means of a pin 11, mar e to pass through three registering perforations. rll'lie pin 11 is provided with a handle 12 for facilitating its manipulation.

For the stamping operation it is necessary that a desired combination of letters be presented downwardly and to insure correct position of the three discs relative to the plate 5 the latter is formed with a single perforation 13 directly opposite the lowerniost set of perforations in the three discs so that when the discs ai'ein proper position for a stamping operation the pin l1 holding the three discs in proper ielation may be pushed on further into the perforation 13 and thereby'properly positions the three discs relative to the plate 5. The' iearmost disk 9 has a heating.

element 14 supported near its rear face, the heating element being connected to a suitable source of electrical power by means of the wires 15.

Itwill be noted that the adjusting means for the discs thus far described allows the latter to move axially on the shaft 6, and for holding` the discs after they have been adjusted to the desired position against axial movement l provide a plurality of set screws 16 which are threaded through the plate 5 and bear against the rear face of the rear disc or the heating element respectively, and a second set of set screws 17 passing through a plate 13 fastened to the front end of the shaft and bearing against the front face of the front Idisc. lt will be readily seen 'that by manipulation of the set screws the discs may be moved on the shaft 6 into any position desired. -V

rFor imparting vertical reciproaatiiig niotion to the plate 5 l use the following mecha.- nism:

A shaft 19 is supported transversely in 'the frame 1 and is connected through a pulley 2O with a suitable source of power. A. fly-wheel 21 is provided for insuring smoothness of operation. A second shaft 22 is supported in the frame in parallel relation to the first shaft and carries an idler gear 23 which meshes with'a pinion 24 on the first shaft and with a large gear 25 on a third shaft 26 passing transversely through the frame 1 so that rotary motion is transmitted from the shaft 19 through the idler gear 23 to the large gear v25 and its shaft 26. The latter carries an eccentric 27 which operates the plate 5 through a connecting link 23 and cross head 29 operatively connected to the plate 5 through two rods 30,with freedom of adjustment through nuts 31. It will be seen that in this manner when the shaft 26 is rotated the plate 5 with its stamping mechanism yis reciprocated between its guide walls 3.

'liie card feeding device may be described as follows: v

A. deck of cards7 indicated at 32, may be confined between the four uprights 33, 34, 35 andl 36, forming a rectangle corresponding substantially tothe size ofthe cards. The upright 33 is formed with-a slotted horizontal extension 3T which is held to the bed kplate by means of a screw 38 passing through the slot so that the upright 33 may be adjusted to allow for dilferent lengths of cards. The upright 36 rises from the left end of a guide bar 39 disposed in a groove 40 extending from left to right throughout the bed plate. rllhis guide bi r is held in place at the eXtreme right end by means of a. screw 41 and in an intermediate section by tlieupright 34 previously referred to. rllie upright 35 rises from the left end of a second guide bar 42 running parallel to the guide bar 39 and along the front edge of the bed. 'Thisguide bar is held to the bed by means of two screws 43 passing through transverse slots 44l in the guide bar so as to allow the latter to be slightly adjusted for different widths of cards. ilhe upright 34 extends over the entire bed plate from front to rear and rests on the two guide bars 39 and 42 for holding the latter in place. lt is secured to the bed plate'by one of the screws 43 and a second screw 45.V

For allowing the lowerinost card tolbe pushed from the deck toward the stamping device the upright 34 is slightly spaced from the bed plate. rFor adjusting the space to a nicety to the exact thickness of a playing card l provide an adjustable gate in the upright- 347 the gate being illustrated in detail in Figure 7 and comprising a small block 46 adapted for upward and downward motion in a recess 47 in the bottom of the upright 34. This block 46 is supported by two rods 43 extending vertically through the upright with freedom of adjustment and 'interconnected by means of a small plate 49 through which a screw 50 threaded so as to beariipon the upper edge of the upright 34. A spring 51'- urges the block 46 downwardvwhile the screw 50'liniits its downward motion toa desired adjustment. A lockniit 52 holds Vthe screw 50 in adjusted position. It willvbe seen thatin this manner the block 46 may be adjusted to card and to prevent a second card from being projected past the upright 34.

As the card is projected through the open'- ing defined by the block 46 and isr advanced between the two guide bars 39 and 42 which are spaced to correspond exactly to the width of the card, it enters under a spring frame 53. illustrated in detail in Figure 6 and comprising two parallel ,bars54, two' transverse give just sufficient clearance for Ya single bars 55 overlying the samel in spaced relation and extending 'beyond the same, and a fifth bar 57v extending intov the rectangle from one kof the bars 55 soas to lie'in the plane of the two bars 54. rThis rectangular frame is supported on two guide bars 39 and 42 so that the extensions of the two Lbars 55 lie on the guide bars while the three bars 54 and 57 lie between the guide bars,"leav" ing sufficient space between the saine and the y bed plate toallow a card to pass underneath the frame while preventing a` second card from passing at the same time, and also holding the card perfectly straight and preventing any buckling. The frame 53 is Vfastened to the two guide bars 39 and 42 by'nieansof screws 58 and springs 59 bearing on the-extensions of the bars 55 so that the frame is capable of slight upward yielding andexerts springs pressure on the card passing underneath. Y Y f For advancing the bottom card I use a pair-of pushers 60 rising through a pair of slots 6l which extend through the bed plate from left yto right to a point substantially in line with' the inner eiidof the bar` 57-0f the frame 53, the ends of the slots 6l allowing the pushers to advance the card directly into printing position. The two pushers are supported on 'a crossy member 62 which is rslidable on a pair of rods 63 supported under- I neath the bed plate, and the cross member 62 is reciprocated by means of a connectinglinkl 64 and an arm 65 fixed to the shaft 22 which latter receives rocking motion from the shaft 26 throughthe arrangement shown in Figure 4 including an arm 66 fixed to the shaft 22, and a link 67 connecting the free endof the arm 66 with a pin 68 projecting eccentrically 'from av disc 69 mounted onl the shaft 26. y

It will be seen that in this manner the shaft 26 through 'the link 67 causes the shaft 22 to rock back and forth which rocking nio-A tion causes the arm and the connecting link '64 to reciprocate the cross bar 62 on the rods 63, thereby causing the pusheis to move back'y and forthin the slots 6l.

For imprinting the characters on the cards I use a ribbon of paper leaf, a product well known in the market and used at the present time for imprinting gold letters on books and for similar purposes. Thus far it has been necessary to print inonograms on" cards by following the conventional printtop of the discs. through the three perforations .correspondmachine I arrange a spool 7 0 of this ribbon on a threaded rod 7l supported in frontof the machine, the spool being held on the rod onv one side by a nut 72 and on the other side by a spring73 and a nut 74, tliespring tend-Y ing to place the spool under tension so that it will not revolve too readily. From this' spool the ribbon is guided over the bed 'plaie' and under thestamping device and betweoz'i ythe guides 7 5/ and is received rearwardly of l the bed plate between two rollers 75 and 76 the former being a large roller made of fairly soft rubber. and the latter being preferably ametal roller which is made to press the ribbon .against the rubber roller.

latter are pivoted on a shaft'78 running alongside the'rear edge of the bed plate and are acted on by the springs 784 for urging the'roller 76 upon the'roller 75..

Intermittent movement is imparted to the roller 75through a rack bar 79 forming part of a slotted frame 8O adapted to straddle the shaftSl on which the roller 75 is supported,v

the rack bar actuating a pinion 82 loose on the shaft-8l and the pinion transmitting ino-y tioii in one direction through ratchet 83 and a pa'wl 84 to a disc 85 fixed on the shaft 8l.

a .manner that an intermediate portion of 'the link 86lieson an eccentric pin 88 extending from a disc 89 fixed to the shaft 26. It will be seen that in this mannerv when the shaft 26 'revolves the pin 88 causes the connecting link 86 to rise and fall which motion is transmitted to the frame 8O and trie rack 79 through a link 9G. 'i '1,

vF or adjustii'igthe length of stroke of the rack rod 79 I suspend the extreme end of the link from a rod 9i which' latter passes a small extension 92 of the bedL plate i.. fthioug.l

and has a collar 93 above the extension 92 -which collarmaybe adjusted by means of a set screw v94. This collar limits the downvward motion of the link vand thereby the length of its upward stroke. A spring 95 bearing on a second collar 96 tendsto urge the link 86 downward so as'to remain in contact with the eccentric pin 88 within the limits set by the collar 93.

The operationof my machine will beun-` derstood from the ,foregoing description'.

'Assuming that the 4three initials ABC are vto be stamped on the cards, the operator i'ii'st Apulls out the pin l fronithe discs and loosens one of the set screws i7 so that the discs are now freely movable relatiif'e lto one an-v He then brings the threellettei's ABC. on thethree discs in the desired alignment,

A stack of cards is placed between the uprights 33 and 34, 35 and 36, and the ribbon is guided over the bed plate so as to be re- 'i ceived between the rollers 75 and 76 at which time the machine is ready for operation. As the power is applied to the shaft 19, rotary motion is transmitted through the idler 23 to the large gear wheel 25 which causes the plate 5 to reciprocate through the eccentric 27, the connecting link 28 and the cross head 29.

In Figure 1 the stamping device is shown in its uppermost position, ready to come down for a printing operation. The pushers 60 are shown in their most advanced position and have just delivered a card into printing position. The ribbon actuating link 86 and the rack 79 are in their uppermost positions and have just advanced the Vribbon so as to expose an unused piece thereof below the stamp. As the revolving motion of the shaft 26 is continued, the lstamping device descends and causes the letters ABC to be stamped through the ribbon on the back of the playing card. During this same part of the operation the pushers have been returned-to their most rearward position back of the stack of cards 32, and the link 86 has returned to its lowermost position'causing the rod 91 to descend and the ratchet 83 to .again advanced.

Asthe rotation is further continued thestamping device rises to its uppermost position while the pushers advance and push the lowermost card into printing position and the link 86 causes the rack bar 79 to rise whereby the ribbon is n The opening, through which the lowermost card leaves, may be adjusted b-y means of the block 46 and the operating mechanism shown in detail in Figure 7, and the card is held, throughout its travel, to the bed plate 'by the spring tension frame 53, the outer bars 511 extending throughout the length of the bed plate to the right and bearing on the card until it leaves the machine, while lthe intermediate bar 57 is shortened so as to clear the card during the stamping operation. Each card is projected over the edge of the machine after it has been stamped, by the new card placed in its position.

In the form shown in Figure 8 a conventional printing unit is substituted for the discl arrangement thus far described. The

plate 5 is slidably mounted in the walls or posts 3 and has ashaft 6 extending therefrom.. The printing unit 100 is suspended from this shaft and may be axially adjusted` by manipulation of the set screw 17 extending through the plate 18 fastened'to the end of the shaft 6. An valigning hole 10. takes the place of the perforations l0 in fixing the printing unit relative to the plate 5. The printing unit consists of a hanger 101 having a bottom flange 102'to which is fastened the type frame 103, a heating unit 14 being interposed' between the flange and the type frame. f
