METALLIC-LEAF-APPLYING ATTACHMENT r03 PRI TING rREssEs.

Application filed. May 3,1924. Serial No. 710,714.

To all whom it may concern:

Be it known that; I, JAMES O. OooN, a citizen of the United States of America, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Metallic-Leaf-Applying Attachments for Printing Presses, of which the following is a specification.

This invention relates to the art of apply ing gold, silver, or aluminum leaf, or the like, to a paper or other surface. While many special machines have been devised for this purpose, such machines are expensive and are usually adapted for no other purpose. For purposes of illustration, I have selected a press in which both the platen and bed oscillate, but it'will be obvious that my invention is equally applicable to other types of presses, such as those in which only the platen oscillates.

One object of my invention is to devise an attachment for ordinary small printing presses which will apply the leaf. automatically to a sheet of paper or the like during the running of the press in the same manner as when run for printing. My attachment may be manufactured as a separate article of manufacture, easily placed on the press and removed when a job is finished.

A further object of the invention is to improve metallic leaf applying machines by rendering them more completely automatic in character, so that fancy labels and the like may be leaf printed (or embossed) with great rapidity. Other objects of my invention will appear as the description proceeds.

Referring to the drawings in which what I now consider the preferred form of my invention is shown Fig. 1 is a side elevation of a standard job printing press with my attachment mounted thereon.

Fig. 2 is an-enlarged detail of the pawl and ratchet feeding mechanism for the strips.

Fig. 3 is a cross section of the throwout cam for stopping the feed.

Fig. 4 is a top view of my attachment showing the guide rollers and feed rollers.

Fig. 5. is a detail of the throwout lever mechanism.

Fig. 6 is a cross section of the pawl and ratchet feed mechanism shown in Fig. 7.

Fig. 7 is a diagrammatic View showing a modified form of the throwout cam.

Fig. 8 is a sectional View of the burners at the back of the matrix.

The standard parts of a small printing press will at once he recognized in Fig. 1. The fixed frame is shown at 1 on which is pivoted the usual platen 2. The large flywheel pulley 3 is j'ou'rnaled on shaft 4 and may be driven from a motor 5' by a belt 6. Pinion 7 on said shaft 4' drives gear 8 on which is pivoted at 9 a crank 10, which oscillates the bed 11 of the press. Said crank is connected, however, to the oscillating member 12 pivoted on the bed, which usually serves to ink the type, but from which the inking rollers have been removed. Platen 2 is connected to member 12 by link 13 to give the former an oscillatory movement. The usual throwout lever is shown at 14. The bed plate is adapted to hold the usual type.

matrix 15. All of the above described parts are well known in the art of presses.

To convert the press into a leaf applying or stamping machine, I replace the usual inking pad on top of the bed by special mechanism 16 comprising a plurality of rollers 17and 18 journaled 1n, parallel side bars The upper rollers 17 receive the white or plain paper on which the lettering is stamped while the lower rollers 18 receive the gold or other leaf paper 41. Each strip is fed from a

roll

40, 41 pivoted on the base of the bed. One of the upper rollers 17 is shown as mounted on pivoted bracket 20, which may be adjusted to bring the knife in the proper relationship to the lettering. Automatic feeding of each strip of paper is provided by means of the

feed rollers

21 and 22 which grip the respective strips between the surfaces thereof and the smaller rollers 17" and 18.

Preferably I provide an independent intermittent feed for. each feed roller. On the shaft 23 of roller 22 is secured ratchet wheel 24, while loosely mounted on said shaft is a second ratchet wheel 25' to the face of which. is secured gear 26. Meshing with said gear is a pinion 27 on the shaft 28 of upper feed roll 21. Both pawls 29 and 30 for the two

ratchets

24 and 25 are pivoted on" an arm 31 loosely journaled on shaft 28 and oscillated by link 82 from member l2" see Fig. 1), so both pawls are oscillated together. A cam agamst turning.

I may also provide a knife mechanism to sever the printed strip into given lengths. As shown, this mechanism comprises a knife pivoted at 46 and linked at its outer end to a link 47. Said link in turn is pivoted at its other end to the lever 48 and intermediate its ends to a second lever 50. Both of said levers are pivoted to an extension 51 on the frame, thereby forming a parallel linkage. Lever has pivoted to its outer end a rod 52 which is clamped in a bracket 53 pivoted to member 12 at 54. By this means it will be seen the knife is given a cutting stroke for every oscillation of the member 12. The length of each strip severed is controlled by varying the rate of feed.

The used gold-leaf paper may, if desired, be rerolled as by providing a roller 55 at the back of the machine (Fig. 4), which may be turned from the shaft 23 as by pulley 56, belt 57 and pulley 58 on the shaft 59 of the roller 55. I If desired also, the printed paper may be rerolled instead of cutting the same into strips or labels. If this is desired, the same or a similar roller 55 may be employed for this purpose.

Preferably I provide means for quickly stopping the feed and thus interrupting the printing operation without stopping the entire machine. For this purpose I make use of the regular throwout handle 14 of the press as shown in Fig. 5, which shows a view looking in the reverse direction from Fig. 1. The handle 14 is connected through

linkls

58, 59, and 60 and lever 61 to an arm 62 on a cam member 63, which is mounted on the hub 80 of disc 68, said disc in turn being mounted on shaft 23. Said member 63 is provided on the face thereof with cam surfaces or lugs 64 which take in apertures 65 in an adjacent member 66 on a shaft 23.

When member 63 is rotated with respect to member 66, the lugs 64 ride up on the edges of the apertures 65 and push the member 63 to the right in Fig. 3. This forces cam 67 to the right, said cam being'the back of disc '68 which supports member 63. raises the rod 70 (Fig. 2 and 3) which in turn lifts the lever 71, having a cross bar 81 attached thereto, thereby raising both pawls clear of the ratchet teeth so that the feed is stopped. Member 63 is normally pressed to the left by means of springpressed plungers 7 2 and 73.

This

ily be seen when the cam is turned clockwise in Fig. 7 that the lever 71 will be raised to lift the pawls as in the other form of the invention.

From the foregoing. the operation of my invention will be readily understood. The movements of the press proper are exactly the same as when used as a printing press. Twosheets of paper are, according to my invention, fed across the face of the type, one being the paper or other article to be stamped with the gold leaf, and the other the gold leaf paper. As the two strips are fed across the face of the type, the bed of the press and the platen are brought together in the usual manner and the gold transferred to the paper where the type is pressed against the back of the gold paper. Both strips are fed together automatically by the mechanism described, the feed of each being varied at will by means of the

adjustable cams

34 and 35. The printed strip may be severed after each print by means of the knife 45 as described while the whole printing operation can be instantly arrested by throwing the handle 14 thereby stopping the feed.

In accordance with the provisions of the patent statutes, I have herein described the principle of operation of my invention, together with the apparatus, which I now consider to represent the best embodiment thereof, but I desire to have it understood that the apparatus shown is only illustrative and that the invention can be carried out by other means. Also, while it is designed to use the various features and elements in the combination and rlations described, some of these may be altered and others omitted without interfering with the more general results outlined, and the invention extends to such use.
