CARD-CUTTING ATTACHMENT FOR PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 687,463, dated November 26, 1901.

Application filed March 21, 1901. Serial No. 52,230. (No model.)

To (ZZZ whom it may concern.-

Be it known that I, WINCHESTER FRANKLIN SPEIGHT, a citizen of the United States, residing at Austin, in the county of Travis and State of Texas, have invented a new and useful Card-Cutting Attachment for Printing- Presses, of which the following is a specification.

This invention relates to the art of cutting cards from a blank of paper, and has for its object to provide a card-cutting attachment for application to printing-presses and arranged to be set up in an ordinary chase in the manner of an electrotype. It is furthermore designed to arrange for the interchange of a plurality of dies, so as to vary the shape or design of the cards to be out, and also to provide for eflectually ejecting the cut cards from the die, so as to automatically maintain the latter free and in condition for action during the successive operations of the press.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings,-and particularly pointed out in the appended claim, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of the present device. Fig. 2 is a central sectional view thereof.

Like characters of reference designate corresponding parts in both figures of the drawlugs.

Referring to the drawings, 1 designates the base or body of the present device, which is preferably in the form of a rectangular block of any suitable material, preferably metal, so as to present a strong and solid backing to the removable die 2, which is fitted flat against the upper face of the body. The die is formed of metal in any desired shape and consists of an upstanding marginal cutting rim or flange 3, which is designed to'cut the card from a blank of paper. The back edge of the die is flat, so as to rest flat against the block 1, and is provided with a plurality of screw-threaded studs or pins 4, which are passed through corresponding perforations in the block, the

outer ends of the pins terminating substantially midway between the top and bottom faces of the body 1, and the bottom of the latter having enlarged sockets or recesses 5 formed at the ends of the perforations for the reception of the nuts 6, that are fitted to the ends of the pins that project into the sockets.

, By this arrangement the back of the block or body is free from projections and the die is fixedly connected to the block. The middle of the block is provided with a perforation for the loose reception of an ejector-pin 7, that has its upper end provided with an enlarged plate-like head 8, which lies within the die. The lower end of the ejector-pin projects into a socket 9, formed in the bottom of the base or body 1, and is provided with a longitudinal screw-threaded opening for the reception of a removable-headed screw 10 to prevent upward endwise displacement of the ejector. The upper end portion of the pin projects a suitable distance above the upper face of the body, so that the disk or head 8 may normally lie in a-plane slightly above or outwardly from the upper cutting edge of the die, and is elastically yieldably held in this position by means ofa spring, preferably a coiled spring 11, embracing the upper end portion of the ejector-pin and bearing in opposite directions against the top of the base and the under side of the ejector-head.

In using the present device it is set up in a chase in the manner of an ordinary electrotype or the like, the thickness of the body and the added height of the cutting-flange of the die being exactly type-high, so that in the operation of the machine the paper, cardboard, or the like is pressed against the die, whereby the cutting-flange cuts out a card corresponding to the shape of the die, and after the pressure is removed from the die the ejector automatically springs outwardly and displaces the card from the die, so that it may be in condition for another operation.

It will be understood that the die is in the form of a marginal flange, there being no bot tom or back closing the interior of the flange, and the pins 4 extend from the bottom or back edge of the flange, which back edge is flat, so as to rest evenly against the base or body, and the upper cutting edge of the flange is beveled inwardly from the outer side thereof to form a cutting edge flush with the inner,

side of the flange. Also it is designed to seat the spring 11 in a corresponding socket or depression 12, formed in the top of the body and surrounding the central opening therein, so as to prevent lateral movement of the spring.

What is claimed is A cardcutting attachment for printingpresses, comprising a block or body having a plurality of perforations formed transversely 'therethrough, with enlarged sockets formed in the bottom of the body and at the lower ends of the perforations, a die consisting of a marginal flange resting against the upper face of the body and surrounding the perforations therein, and provided with a plurality of screw-threaded studs or pins inserted through the corresponding perforations in theiliibody and terminating within the respective sock ets, nuts removably applied to the lower ends of the pins and lying Within the sockets, an

ejector-pin slid-ably extending through a central perforation in the body, the upper end of the pin having an enlarged ejector-head, and the lower end having a nut applied thereto and fitting in the adjacent socket and forming a stop to limit the upward movement of the pin, and a spring bearing in opposite directions against the body'and the head of the ejector-pin.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
