FRANK'DE MINICO, OF NEW YORK, N. Y.-, ASSIGNOR TO POLLARD-ALLING MANUFAC- TURING COMPANY, OF NEW YORK, N. 2., A CORPORATION OF NEW YORK.

PRINTING acrame.

ToaZZ whom it may concern:

Be it known-that I, FRANK DE MINIoo, a citizen of the United States, and a resident of New York, borough of Bronx, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Printing Machines, of which the following is a specification.

This invention relates to printing machines and particularly to that class thereof which is adapted for printing from small embossed plates such as shown in Fig. 7 of Letters Patent of the United States No. 866,863 of September 24, 1907 to G. F. Hopkins.

The object of my improvements is to provide a machine of the class specified, of simple construction, and which can be rapidly and easily manipulated for printing upon envelopes, labels and the like.

' With these ends in view and others which will appear hereinafter my improvements comprise features illustrated in their preferred embodiment in the drawings'accompanying this specification, wherein:

Figure 1 is a perspective viewof-my improved machine. Fig. 2 is a side elevation partly in section on line 22 of Fig. 3. Fig. 3 'is an end view in'section on line 3-3 of Fig. 2. Fig. 4 a fragmentary elevation showing a detail of the machine.

While for quantity production it is customary to employ the above mentioned embossed'plates assembled into a continuous chain andwhich chain of plates is fed automatically through an elaborate machine, in

many cases it'is desirable and convenient to print from the plates one at a time and my present machine is for such purpose.

' Table 2 may be conveniently mounted on legs, as 3, preferably having rubber feet, as 4. In the front end of said table about midway its width is depressed portion forming a seat onto which an individual prlntlng plate 6 is slid, under ink ribbon 7. Said ribbon is mounted on opposite spools 8, 9, being fed from' one to the other as required, by turning the receiving spool by hand. Ribbon 7 passes from spool to spool, crosswise over table 2 and beneath top-plate l0, and which plate has an opening at'the printing end of the machine between portions 11 and '12, directly over seat '5 for the printing plate. An envelope 13 or other article to be printed is placed, face down, on top-plate Specification of Letters Eatent.

Application filed June 9,1921. Serial No. 476,120.

10, with the portion on which .it is desired to print over the opening between portions 11 and 12. Directly below that portion of said envelope over said opening, and below plate is ribbon 7 and below the ribbon is printing plate 6, with its embossed characters face up. With the several parts and the envelope in the described positions it is obvious that any downward pressure brought-to bear on that portion of the envelope over the opening in plate 10 will cause the embossed characters on printing plate 6 to press the ink ribbon against the under face of the envelope, thereby printing those characters on-said envelope. To accomplish this result I preferably employ the following means: Upstanding from table 2 near that end remote from the printing plate seat 5 are ears 14, 15 spaced apart sufficiently to permit the free reciprocation therebetween of lever 16. Said lever is slotted at 17 and is retained between said ears by pin 18 extending through said ears and through said slot. The leveris thus permitted to swing up and down on said pin and to move a limited amount back and forth lengthwise the machine parallel with printing plate seat 5. Fixed to the rear end of said lever is weight 19, and near the forward free end of said lever impression roll 20 turns freely on stud 21 outstanding from said lever. Saidroll is preferably of some yieldable material such as rubber and is adapted to traverse back and forth over the length of plate 6 as permitted by slot 17 of lever 16 on pin 18. On that side of lever 16 opposite roll 20 is mounted on eccentric pin 22 gage roll 23 for engagement with plate 10. This-roll 23 is eliicientfor gaging and maintaining the distance of impression roll 20 from plate 6 as that roll 20 is moved to perform its work. Said eccentric pin 22 may be rotated to move roll 23 up or down relatively to .roll2O and may be held in any adjusted position by set screw 24'. A suitable handle 25, projecting from the free end of lever 16, is used to operate said lever. The weight. of that portion of lever 16 and its appurtenances to the right of pin 18, when that lever is in its forward position, Fig. 1, is greater than the weight of that portion including weight 19 to the left of said pin, but when said lever is pushed its full stroke to the left, that left hand end overbalances the right hand end.

These features contribute to the following mode oi operation :v In its: idle position lever 16 stands as shown indotted lines in Fig. 2. its weighted end being down, and the end carrying the rolls and handle being pointed upwardly near the rear end of the machine. A; printing plate 6 having been inserted on seat 5 below ribbon 7 and. an, envelope having been placed in position above said ribbon on late 10, handle 25. is graspedand lever 16' swung. downwardly and pulled for.- wardly until. the left. hand end of! slot, 1'7. engages pin. 1.8, F ig. 2. Then. the lever is further lowered until roll. 23 encounters plate 10, at which time roll 20 will engage envelope 13 with the requisite amount of pressure, roll 28 having been previously ad: JHStQd to that. end, The several parts will then be as shown in Fig. 1 with roll 2.0 at the beginning of. its, stroke, Handle is then pushed to the left, Fig. 2,. and at the same time a gentle downward pressure is maintained} to keep roll 23 in contactwith plate 10. B01120. is thus, caused tov traverse over the envelope the distance permittedi'by fixed: pin, 18 in slot 17, that is, over the length of the printingplate. The handle is then released and the end carrying'weight 19 immediately drops,. thereby lifting rolls 20,23 from the table. The envelope is then free to be removed and another inserted; At this time another printing plate may be. sub-. 'stitutedffor the one just used and. from. time to time the ribbon is shifted to ajfresh portion as needed.
