METHOD OF MAKING HORSESHOES.

Application filed February 3, 1928. Serial No. 251,646.

The invention to be hereinafter described relates to a method of making horseshoes.

A purpose of the invention is to provide a shoe which will get a good bite or grip on icy, wet and other pavements or surfaces, and a shoe which is strong, simple and durable in construction and can readily be manufactured on a large commercial scale.

\Vith the above and other purposes in view, the character of the invention may be best understood by reference to the following description of the methodand the accompanying drawings, wherein- Fig. l is a plan of a horseshoe embodylng the invention;

Figs. 2 and 3 are respectively longitudinal and transverse sections through the horseshoe shown in Fig. 1;

Fig. 4t is an elevation of rolls employed in the first two stages in shaping the bar;

Fig. 5 is an elevation of rolls employed in the last two stages in shaping the bar and in marking and finishing the bar;

Fig. 6 on anenlarged scale is a view showing the forms taken by the bar in successive stages in shaping the same;

Figs. 7 and 8 are respectively views of the billet;

Fig. 9 is an end view of the bar drawn out from the billet by the roughing rolls;

Fig. 10 is a plan of the connected pair of bars formed by the rolls;

Fig. 11 is an end view of said bars; and

Fig. 12 on a reduced scale is a plan of a portion of a finished pair of bars.

Referring to the drawings,

side and end the horseshoe shown in Figs. 1, 2 and. 3 is one good form I produced by the method and comprises a body 1, wedge-shaped in transverse cross section from the heels 8 to the toe 5 of the shoe and presenting a fairly sharp tread edge 7 which extends continuously along the heels, quarters and toe of the shoe.

Projecting out from the-body is a flange 9 having nail holes 11 therein. The wedgeshaped body has an inner side ISeXtending from the top face 17 the shoe to the tread edge, and an outer side 19 extending from the flange to said edge;

In the method of making horseshoes einbodying the invention, a suitably heated steel billet 20 (Figs. 7 and 8) is passed through roughing rolls to draw it out into the form of a long bar '20" (Fig. 9) preferably square in cross section. These rolls are arranged in a group of three, one above another, and adjacent rolls have opposed grooves therein, being so shaped that as the billet is fed successively in opposite directions between the rolls, it receives four stages of reduction.

This bar is fed while heated between rolls and is shaped in successive stages to final form. To accomplish this, a shaft 21 (Fig. 4) is provided having-thereon a roll 23 mat ing with a circumferential groove 25 in a roll :27 on a shaft 29, said. groove being formed so that when the bar is fedbetween the rolls, it will receive its first stage of shaping and have the form indicated by the dot and dash linea (Fig. 6). 011 said shaft 29 is a roll 31 opposed to a circumferential groove 33 in a roll 35 on a shaft 36, said groove being formed so that when the bar is fed between said rolls, it will receive its second stageof shaping and have the form indicated by the double dot and dash line b (Fig. 6).

A marker roll 37 (Fig. 5). is provided on a shaft 89 and is opposed to a circumferential groove 1-1 on a roll 43 on a shaft 14, said groove being formed so that when the bar is fed between the rolls, it will receive its third stage of shaping and have the form indicated by the triple dot and dash line a (Fig. 6).

The groove 41 has punch points 15 thereon for making the depressions 46 (Fig. 12) in the bars for indicating the locations of transverse cuts to be made in dividing the bar into lengths suitable for horseshoes. Also, the groove 41 has punch points 47 thereon for making depressions 41:8 in the bar to indicate locations of the nail holes.

A finish roll 51 (Fig. 5) on shaft 14 is opposed to a circumferential groove 53 in a roll 55 on a shaft 56, said. groove being formed so that when the bar is fed between the rolls it will receive its fourth and final stage of shaping and have the form indicated by the full line (Z (Fig. 6). Th finishing rolls will finish the surface ofthe bar and remove any distortion thereof which may have occurred in the preceding shaping stages.

The bar has now been rolled from its form shown in Fig. 9 to its form shown in Figs. 10 and 11, and comprising two wedge-shaped bodies or bars 1, outstanding flanges 9 and a web 1" connecting said bodies. The edges or apexes of the bars are opposed to the bases of the bars. After the bar has cooled the web is sheared. longitudinally to separate the two bars. To facilitate the severing operation and insure clean cut edges, a scoring rib 51 may be provided on the roll 51, so that when the connected bars are fed between the finishing rolls, the rib 51 will score the bar along the web l (Fig. 6).

The bars are transferred to a punch machine to make nail holes in the flanges oil the bars at locations indicated by the depressions 48 made by the punch points 47 of the marker roll 43. The bars are cut transversely at locations indicated by the depressions 46 made by the punch points 4-5 of the marker roll 4L3 to provide pieces of suitable length for forming horseshoes. These pieces are placed in a bending machine to bend them to horseshoe form.

It is desirable that a bar shall be used of a size appropriate for production of a pair of connected side-by-side Wedge-shaped bars, since this symmetrical shape facilitates feeding of the piece between the rolls and reduces the liability of distortion and reduces strains on the rolls.

A pad 59 of leather, rubber or other suitable material may be employed between the shoe and hoof if desired.

There are important advantages in the horse shoe of the present invention. The sharp tread edge of the Wedge-shaped body directed vertically downward and therefore bites into and obtains a good grip on pavements. Since this tread edge is continuous from one heel to the other, it grips pavements throughout its length and resists slip in.

all directions. Said edge provides a long tread surface, desirably distributes the wear over the Whole extent of the edge, and insures proper position of the horses hoofs. The shoe is simple and strong in construction and has a pleasing appearance. The shoe is desirable and suitable for both summer and winter use.

It Will be understood that the invention is not limited to the specific forms shown, and that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.

vVh at is claimed is:

1. A method of making horseshoes having continuous sharp tread edges, characterized by rolling a metal billet to draw it into a bar of substantial length, rolling the bar to shape it into a pair 01"- bars connected by a web and having portions Wedge-shaped in transverse section with continuous tread edges and having outstanding flanges, rolling the bars progressively to increase the sharpness of said tread edges and progressively to reduce the thickness of said flanges, and shearing the web longitudinally to separate the bars.

2. A method of making horseshoes having continuous tread edges characterized by rolling a metal billet to draw it into a barof substantial length, rolling the bar to shape itinto a bar having a portion Wedge-shaped in transverse section with an outstanding flange, rolling the bar progressively to increase the sharpness of said tread edge; and progressive ly to reduce the thickness of said flange, rolling the bar to give it throughout its length the final, finished cross-sectional formit is to have in horseshoes, cutting the bar transversely at intervals into lengths suitable for horseshoes, and bending the short lengths into horseshoe shape.
