' METHOD OF FORGING OX-SHOES.

$PECIFICATION' forming part of Letters Patent No. 314,190, dated March 17, 1885.

Application filed August 21, 1884. (No model.)

To all whont it may concern:

Be it known'that I, WILLIAM Pearson, of Plantsville, in the county of Hartford, and in the State of Connecticut, have invented certain new and useful I Improvements in the Manufacture of Ox-Shoes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of the lower die employed in the manufacture of oX-shoes of ordinary shape by my process. Fig. 2 is a likeview of the barof-metal used as ablank in connection therewith. Fig. 3 is a plan view of said die with said blank shown in dotted lines in position for impingement of the upper die. Fig. 4 is a like view of the same afterthe upper die has performed its office.

Fig. '5 is a plan view of the die used for forgingan oX-shoe with parallel calks, the blank being shown by dotted lines in position for the operation of the upper die. Fig. 6 is a like view of the same after said upper die has,

impinged upon said blank, and Figs. 7 and 8 are respectively perspective views of blanks after having passed through the dies shown in Figs. 1 and 5. j y

Letters of like name and kind refer to like parts in each of the figures.

In the manufacture of oX-shoes by dies it has heretofore been necessary to employ a blank which had substantially theform of the finished shoe, which form was given by heating the end of a bar of metal of suitable size and then bending the sameinto acurved form. The bent position of the bar thus employed would, under the action of the dies, have atendency to resume its original straight form, which tendency wasnot regular, and could not be relied upon, so that it was necessary to employ iron considerably larger in transverse dimensions than would have otherwise been required, in order that the die might be completely filled each time. To obviate these difficulties, and to materially lessen the cost of the completed article, is the design of my invention, which invention consists in the method employed forgforging ox-shoe's, whereby a straight heated bar may be used without other preparation, substantially as and for the purpose hereinafter specified.

In the carrying out of my invention, I employ a lower or female die, A, within the upper surface of which is formed a recess, a, that corresponds to the general shape of an oX-shoe, and at each end is provided with deeper recesses a and a, respectively, for the production of the heel and toe calks of such shoe.

The die A being placed within a drop-press or other equivalent means for operating dies where it may be subjected to the impingement ofa plain-faced upper die, a plain bar ofmetal, B, is heated and placed upon said die A in substantially a line with the transverse centers of the calk-recesses a and a, as shown by dotted lines of Figs. 3 and 5, after which one or more blows are given by the upper die, and the metal caused to fill the shoe-intaglio. When the bar B is in position for operation,

more of the recess a is upon the outer side of said bar than at the inner side of the same, but the downward and outward inclination of the central portion of said recess causes the metalto flow in such direction, so as to completely and perfectly fill the space.

By means of myimproved method a saving is effected of from one-seventh to one-sixth in the size and weight of metal used, one heat and one manipulation is avoided, and one person is enabled to forge and trim a shoe at one heat, when formerly two persons were necessar y and the metal required to be heated twice" in order to accomplish the same result.

Having thus fully set forth the nature and merits of my invention, what I claim is As an improvement in the forging of oxshoes, the hereinbefore-described method, consisting in the placing of astraight bar of heated metal having less width than the finished shoe over the intaglio of an oX-shoe die in substantially a .line with,the transverse centers of the calk-recesses and subjecting the same to one or more blows by an upper or impinging die, substantially as and for the purpose specified.

In testimony that I claim the foregoing I' have hereunto set my hand this 11th day of August, 1884.

WILLIAM PEARCE.
