DIE FOR MOL'DING HORSESHOE-BLANKS.

SPECIFICATION forming part of Letters Patent No. 265,909, dat-ed October 10, 1882.

Application filed February 24, 1882. (No modeLi To all whom it may concern Be it knownthat I, DARIUs WILcox, a citizen of the United States, residing at Derby, in the county ofNew Haven and State of Connecticut, have invented a new and useful Improvement in Dies for Making Horseshoe-Blanks, of which the following is a specification.

My invention consistsin dies by which horseshoe-blanks can be completely formed and iinished in readiness for bending, so as to produce a complete and salable horseshoe by bending in a suitable machine, without the necessity of subsequent stamping in finishing dies. To this end I employ a pair of dies having matrices to form the two ends of the blank in succession. Each matrix has at its rear end a suitable pocket to form the heel-calli, and

- near its front end a pocket to form a toecalk, so that, somewhat more than one-half the blank having been formed at the first o'peration, the blank is removed to the second matrix and the i toe-calla already formed is placed in the corresponding pocltet ofthe second matrix, which thus serves to accurately gage the length of the finished blank. I prefer to stampcach end of' the blank at two successive operations in two die-cavities, by which means I am enabled to produce rudimentary nailcreases in the first and complete them to their full depth at the second stroke.

ln the accompanying drawings, Figure 1 is a side View of' a pair of' dies adapted for carrying out my invention, theshape of the diecavities being indicated in dotted lines. Fig.

2 is a front end view ofthe same. Fig. 3 is a face view of the bed-die. Fig. 4 is a face View of' the top die or punch. Fig. 5 is a perspective view of a blank. Fig. 6 is a perspective vicw of trimming-dies employed for removing 40 the fins. Fig. 7 is a transverse section of the same. Figs. S and 9 are face views of' dies employed for forming the bottom and creased horseshoe-blank by two operations on each end thereof.

The blank is preferably formed in inverted position, as shown but the dies may be used either side up, as preferred.

blocks F F, which are made removable for repair or renewal. I prefer to employ for each end of the shoe two matrices for successive use with creasers ff of unequal depth, so that y rudimentary creases may be formed at the first operation and the crease completed at the second. One end of the blank is first formed, either at one operation in the matrix M by the dies shown in Figs. 2, 3, and 4, or at two operations in the successive matrices M M ofthe die shown in Fig. 8 and a corresponding beddie, which is not shown, but is precisely similar to the die B, Fig. 3, excepting that the two cavities are of' corresponding shape and position, instead of' being reversed. The partlyformed blank is then placed with its unfinished end in the matrix lll and the already-formed call; in the pocket Q', to serve as a gage. The second end is then stamped, either at one operation in said matrix M of' the die shown in Figs. 2, 3, and 4 or at two operations in the die shown in Fig.9. itis then passed through the trimming-dies shown in Figs. 6 and 7, to remove the fins. A

Having thus described my invention, the following is what I claiin as new therein and dcsire to secure b v Letters Patent:

The combinal ion of' a die having parallel matrices, containing front and rear pockets, and removable ciease formers or ribs, arranged substantially as shown, willi a second die provided with matrices having continuous or nubroken bottom faces, as and for the purpose Witnesses OcrAvfUs KNIGHT, WALTER ALLEN.
