DIE MOUNTING.

Application led February 10, 1922.

To all whom t may concern:

Be it known that l, CHARLES A. Knorr, a citizen of the United States, and a resident of the city of River Forest, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Die Mountings, of which the following is a specification. y

My invent-ion relates to improvements in die mountings, especially adapted for use on drop hammers, punch presses and the like, and has for its object the provision of an improved construction of this character by means of which dies for such machines may be economically manufactured and readily and securely mounted on such machines.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying' drawings forming a part of this specification, and in which, y

Fig. 1 is a top plan view of a construction embodying the invention;

Fig. 2 is a top plan view of the die holder employed in said construction;

Fig. 3 is a bottom plan view of the die body illustrated in 1;

Fig. l is a transverse section taken on line 4 4 of Fig. 1; h

Fig. 5 is a side view of the construction; and

Fig'. 6 is a horizontal section taken on line G-G of Fig'. ll.

The preferred form of construction as illustrated in the drawings comprises a die holder 7, the body of which is of any usual or desired construction for mounting in a drop hammer, punch press or the like. The upper surface of the body 7 is provided with a linished surface 8 adapted and arranged to constitute a seat for the die body, and a substantially semi-circular socket 9 is arranged substantially centrally of the surface 8. The circular side 10 of the socket 9 is undercut or beveled as shown, and the portions 11 of the walls of said socket formed vertical, a taperingv inclined keyway 12 being' cut in the body 7 traversing the side of the socket 9 opposite the under out wall 10. The die body 13 -is provided with a flaring stem 14 arranged to fit between the walls 11 and flared to Serial No. 535,483.

nicely fit the undercut wall 10. rlhe side 15 of the stem la is flattened and beveled to correspond to and register with the corresponding' side of the keyway 12. The under` sur* face of the die body 13 is nicely finished to rest upon the surface 8 and the bottom of the stem 14; is nicely finished to rest upon the bottom of the socket 9. A taperingor wedge-shaped key 16 is tted into the socket lf2 to contact as shown with the flattened side 15 of the stem 1lfor holding Said stem and said die body in place. The die body 13 may be provided with any desired form of die 17, the one indicated being a die for a 2(rear blank, as will be readily understood.

By this arrangement the die body may usually be made of circular stock or material to be finished in a lathe, which ,greatly facilitates the process of manufacture and the economical production thereof. A firm and secure seat and support is also provided for the die body whereby movement thereof under the heavy strains incident to use is prevented. Likewise there is and can be no strain or pressure upon the locking key so that it is impossible for the die to work loose in use. rllie form of construction illustrated is one capable of very economical manufacture and production, from `a minimum of stock. The specific form and arrangement of parts illustrated is a simple and effective one for the purpose.

While l have illustrated and described the. preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. l, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modiiications as come within the scope of the appended claims.

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

1. A die mountino comprising a body provided with a stem; a holder having?,` a socket therein somewhat larger than said stem to permit direct insertion of said stem and lateral movement of said stem in said socket` the walls of said socket and the sides of said stem being arranged to engage with each other upon lateral movement of said stem in said socket; and means for securing said stem in said socket in interlocking,` relation with the walls thereof, substantially as described.

2. The combination with :L die body provided with a circular stem having :t flattened side, of u holder having),` it substantially semicirculur socket therein, said stem being adapted and arranged to be inserted in said socket und engage therewith by lateral movement therein; und ineens engaging' the fluttened side of said stem for locking' the same in said socket, substantially es described.

3. A die mounting' comprising a. holder having a substantially semi-circuler socket therein and u key way traversing' the flat side of said socket; e die body provided with e substantially circuler stem having;` u flattened side fitting into said socket and engaging; therewith by lateral movement therein; und a key insertable in seid key way and engaging' the fiattened side of seid stem to secure the stem in said socket, substantially as described.

4. A die mounting' comprising a holder having e substantially semi-circuler socket therein, the circular portion of said socket i beine under eut there beineV u ke wa. f trav- 'ersing the flirt side of said socket; e die body provided with a substentiallvconieal stem itting within said socket und having e lattened side; and u wedge shaped key insertavble in seid key way and engaging the flattened side of said stem to secure the same in said socket, substantially as described.

5. A die mounting comprising :i holder having a socket therein, the one side of the wall of Suid socket being' undercut and 5L keywuy traversing` the other side of seid socket, the intermediate walls of said socket being straight; a. die body provided with a stem adapted to fit between seid straight walls of said socket, seid stem being flared to fit the undercut wall of Said socket, the side of said stem corresponding` with said keywzty being beveled; and a wedge-shaped key insertable in seid lieyway and engaging' the bevelled side of suid stem to secure the same in Said socket, substantially as described.

In testimony whereof l have signed my name to this specification in the presence of two subscribing' witnesses.
