DIE FOR FORMING OX-SHOES.

SPECIFICATION forming part of Letters Patent No. 359,961, dated March 22, 1887. Application filed January 26, 1887. Serial No. 225,609. (No modelii To all whom it may concern.-

Be it known that I, JOHN DEEBLE, a citizen of the United States, residing at South ington, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Dies for Forging Ox- Shoes, of which the following is a specification.

My invention relates to improvements in dies for forging ox-shoes; and the objects of myinvention are to more perfectly fill the dies at the calla-recesses and to generally improve the efficiency of the dies.

In the accompanying drawings, Figure 1 is a face view of the die which I prefer to use at the top. Fig. 2 is a like view of the companion or bottom die. Fig. 3 is a vertical section on line or o: of Figs. 1 and 2 of both of said dies, and Fig. 4 is a like view of the same with calk-recesses adapted for forming sharp calks.

A designates the die-block which I prefer to use as the upper die-block, and B the lower In the block A, I prefer to form two die-depressions, the depression a being of the general form of a finished shoe, less the nail-groove, and the depression I) is the finishing-die, having a rib, c, for forming the nailgroove, as in former dies. Instead, however, of making these depressions of the full depth throughout, I only make the middle portion, or the portion which lies between the call:- recesses 12, of the depth for forming the whole thickness of the shoe, less the fin, while the face of the die is cut away at each end to make the calk-recesses 1 2 only about one-half the usual depth.

In the die-block B, I form partial calk-recesses 3 4 for each of the depressions a b, and in such position as to register therewith when the dies are brought together. These, like the calk-recesses 1 2, are only about half the usual depth, and the die-block is made thicker near each edge than at the middle portion to enable the bottom of these recesses to be in the same plane as the surface of the middle of the die. In both blocks the junction of the thicker and thinner portions is beveled off to avoid an abrupt shoulder. Thus it will be seen that although the middle portions of the die-depressions are in only one block, the calkforrning recesses are formed partly in the upper and partly in the lower dieblock.

In use a heated bar of iron, either straight or bent edgewise, as may be desired, is placed upon the lower die-block, B, in position to come under the preliminary impression on of the upper block, the calkrecesses 3 4 ena bling the operator to properly locate the bar on the block. The bar is then struck by the upper die-block, and then changed in position on the lower block, to bring it under the depres sion 1) for the finishing stroke.

The fin or surplus metal is trimmed off by cutting-dies in the ordinary manner.

By placing the die having the main depressions at the top better work is believed to be performed, on account of the tendency of hot iron to come toward the hammer that strikes it, and, furthermore, the depressions are better kept free from scales or other matter, which often lodge in such dies when used at the bottom and cause imperfect work. Such dies cannot readily be used on the top in connection with the ordinary plain-faced block or hammer; but with my block B the calk-recesses 3 4 furnish the operator a ready means for placing the bar in proper position. By making the bottom of the calk-recesses in the block B in the same plane as the mid dle face of said block they are readily kept free from scales or other refuse by an ordinary air-blast.

The dies shown in Fig. 4 are the same as the others, except in the shape of the calkrecesses 1 2, which are adapted for forming sharp calks. Such calks have not to my knowledge been heretofore forged in dropdies. By forming the calla-recesses in the two die-blocks I can readily form such calks. While I prefer to employ two depressions to be used one after the other, as described, and divide the calk-recesses for both die-depressions, it is evident that my invention is applicable to die-blocks which have either the preliminary or finishing die-depressions, I die-depression, with the calk-recesses formed and thatverygood results may be had by thus 1 partly in each of said blocks, substantially as dividing the caulk-recess for the preliminary I described, andfor the purpose specified.
