Patented J an. 18, 1916.

Application filed June 17, 1914. Serial No. 845,561.

To all whom it may concern:

Be it known that I, MARTIN HAes'rRoM, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Leather- Blank-Cutting Dies, of which the following is a specification.

This invention relates to improvements in leather blank cutting dies and its object is to produce a device of this class that is simple in construction, efficient in operation "upper end of each plunger is t punch press for engagement and cheap to manufacture.

With the foregoing and other objects in view the invention consists in the combinationand arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claim and illustrated in the accompanying drawing which forms a part of said specification and in which Figure 1 is a view of the material after the same has been operated upon by my improved die. Fig. 2 is a side elevation, partly in section, of my improved cutting die. Fig. 3 is a top plan of the same.

' Like reference characters indicate corresponding parts throughout the'several views.

My die comprises a male member 1 which is of the shape of the finished product and is formed at each end with an integral extension 2 which engages a post 3 carried in terminal sockets 4, 4 formed in the female die 5. The male member, moreover; is pro- Vlded, Wll'/h a stem 6 adapted to fit into the by which the device is operated.

The female member 5 is of hollow formation and isprovided with a lurality of interior integral studs 7 which are threaded with apertured caps 8 through which the plungers 9 extend into said studs and each of said plungers is provided with an encircling sprin 10 and the readed and screwed into engagement with the receiving plate 11 supported by said plungers. The member 5 is formed with a peripheral cutting edge 12 formed adjacent to the platell'. The blank leather to be cut is placed upon the plate 11 and the male member 1 is then forced down upon said plate depressing the same below the cutting gages the leather and cuts from the blank a piece of the exact shape of the plate 11. When pressure is released the spring 10 will force the plungers 9.and plate 11 back into normal position leaving the finished product, as shown in Fig. 1, upon the plate 11.

What is claimed is In a leather cutting die, formed with terminal sockets, hollow threaded interior studs made integral with said member, caps for said studs, plungers extending through said caps and into said studs, a receiving plate carried by said plungers, springs encircling said plungers and abutting said caps and receiving plate, a cutting edge formed upon said female member adjacent to said receiving plate, posts slidably carried in the sockets of said female member, and a male member comprising a plate in alinement with and of the same shape as said receiving plate and formed with terminal extensions in engagement with said posts and with a centrally disposed upwardly extending stem whereby said male member may be positively depressed into engagement with said receiving plate to depress the same below the cutting edge of the said female member.

Intestimony that I claim the foregoing as my own I have hereto affixed my signaa female member ture in the presence of two subscribing wit- ALANSON V. BRAINERD, CHARLES ENGSTRAND.
