AUTOMATIC DELIVERY DEVliJE FOR PLATENS 0F PRINTING-PRESSES.

SPECIFICATION forming part ef Lettere raient N0. 742,980, dated November e, "1908. Appteeeen nea Meret 16,1903. serial ne. 147,895. (ne man.)

in the county of Cook and State of Illinois,`

have invented certain new and usefful Im- `provements in Automatic Delivery Devices for Platens of Printing-Presses, of which the following is a specification. uff.

My invention relates to certainlnew and useful improvements in automatic delivery devices for platens of printing-presses, and is especially adapted for use on'presses op` erated by hand-levers.

The object of my improvements is to provide a device which may be attached to the press-platen and which will automatically remove cards, envelops, and the like therefrom during the operation of the press, thus saving the pressman loss of time and permitting the press to be operated much faster than when the printed matter is removed with the hand, as is usually done. jects by means of the mechanism illustrated in a preferred form in the accompanying drawings, in which- Figures l and 2 are views in side elevation of a printing-press bed and platen having my device attached thereto and in two operative positions. Fig. 3 is a face view or front elevation of the platen, showing one part of my device attachedthereto. Fig. 4 is a side View in elevation of the part of myinvention shown in Fig. 3, but detached from the platen. Fig. 5 isa top plan view of the part of my invention which is adj ustably attached to a portion of the press-frame, and Fig. 6 is aside elevation of same.

Referring to the drawings in detail, A represents the frame, to which the press-bed B is secured in any usual manner, and C the platen, which is bolted to the arms D, which are hinged on the frame R.

The parts thus far enumerated are of the character and arrangement in general use in platen-presses of Well-known types `and form no part of my invention proper, which is applicable to any platen-press.

E represents a clamp which has jaws c adapted to receive and be secured to the lower edge of the platen by means of the thumb-screw c2, which passes through the upper or rear jaw of the clamp and frictionally I attain these ob-` engages or impingesv against the lower edge ofthe rear side of the platen.

H represents a lever which is preferably formed from a single piece of sheet metal and pivotally secured to the said clamp by means of a pivot es, passing through an opening in the lower corner of the clamp and through the ears h', formed on each side of the lever.

K is a tongue or strip of metal adj ustably connected to the front part of the lever by means of the overhanging edges of the ears h2, formed on the lever below the ears h' and at right angles thereto, as shown in Fig. 4:. Said tongue has a fiat thin point at its upper end adapted to lie close against the face of the platen and back of the lower edge of a card, envelop, or other matter to be printed, as L. The tongue is slidably held between the ears h2, and therefore adapted to be moved up or down on the lever, as desired, the frictional contact being sufficient to hold it in any adjusted position. The rear or outer end of the lever is bent downward, as shown, to form a hook ha, which is adapted to engage the upper edge and point of a dog M, pivotally mounted in a standard N, adj ustably secured to a portion. of the frame R by means of a bolt S, which passesthrough a slot n in the standard and through the slot fr in the frame R. By means of these slots and bolt the dog may be adjusted to any desired position relative to the position of the lever, and the latter may also be suitably adjusted by securing the clamp E at different points along the lower edge of the platen.

In use my invention operates thus: When the platen is in the position shown by the full lines in Fig. 1, the hook ou the lever is below and engaged by the outer point of the dog.

`As the platen moves forward toward the type `or press-bed the lever H follows and turns the dog backward and upward until it assumes the position indicated-by dotted lines in Fig. 1, in which position it releases the dog, which then swings back into its normal position. Then as the platen recedes from the type the hooked end of the lever restsupon the upper adjacent edge of the dog, and as the lever moves back on the dog, which is preferably inclined upward toward its point, the upper end or point of the metal tongue K is moved outwardly from the platen, as

ICO

shown by dotted lines in Fig. 2, and the point of the tongue being behind the lower edge of the card pushes one end of the latter from contact with the gage-pin c', whereupon the card (which has its opposite end still resting upon the gage-pin c2) makes a quarter-turn and drops by gravity endwise into any receptacle which may be provided below the platen.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the frame and platen of a printing-press, means for delivering the printed matter, such as cards, en- Velops and the like, said means comprising an adjustable tongue adapted to lie against` the platen and back of the printed matter, a

Vholder for said tongue, means for adjustably attaching the holder to the platen, and means for automatically operating said holder.

and means for automatically operating said lever. Y

3. In combination with the frame and platen of a printing-press, means for delivering the printed matter, said means comprising a vertically-adjustable tongue adapted to lie against the platen and back of the printed matter, a lever having portions adapted to hold said tongue, means for attaching the lever to the platen, and adjustable means for automatically operating said lever.

4:. In combination with the frame and platen of a printing-press, means for delivering the printed matter, said means comprising a slidably-mounted and vertically-adj ustable tongue adapted to-lie against the platen and back of the printed matter, a clamp adjustably secured to the platen, a lever pivotally mounted on said clamp and supporting said tongue', and a dog adjustably mounted on the frame and adapted to operate said lever upon the movements of the platen.

In testimony whereof Iafix my signature in presence of two witnesses.

JAMES R. FOX.
