JACOB RUSSELL, OF NEW YORK, N. Y.

Specification forming part of Letters Patent No. 150,085, dated April 21, 1874; application filed January 22, 1874.

To all 'whom it may concern:

Be it known that I, .Moon RUssELL, or the city, county, and State of New York, have invented an Improvement in Roller Dies for Shaping and Forming Blanks for Horseshoes ont of Continuous Bars of Metal, ol' which the following is a specification:

In my invention of an improvement in blanks for horseshoes, patented January 6, 1874, is shown the object of my present invention, which consists in a combination of rolls for rolling blanks, in which the face of the dieroll is shaped so as to form the toe-supportin g reserve of metal in the blank.

But to describe my invention more particularly, I will refer to the accompanying drawings forming a part of this specification, the same letters of reference wherever they occur referring to like parts.

Figure 1 is a front view of the rollers or machine. Fig. 2 is a vertical sectional view of the sa-me through the rolls. Fig. 3 is a plan view of a blank or' metal as delivered from the rolls, and ready to be divided into the proper lengths to form the shoe. Y

Letter A represents the frame, in which the rolls B and O are arranged, on suitable axles D, running in adjustable boxes in the frame of the machine. The roll B is the anvil, and is made on a true circle, with two cheek-pieces, E, to support the blank of metal laterally while being shaped by the die-roller O. This roller is made circumferentially the length of two horseshoe-blanks, having' at the points F chisels or critters for cutting ott' each horseshoe-blank as the bar ot' met-al passes between the rolls, as indicated at G, Fig. 3. On the face of the die-roll O at one edge, and at its middle part, lengthwise of its greatest diameter, are cut ont two concave segments of metal, H, whereby the blank of metal will be thickened at that point, as shown at I, Fig. 3,

to form a reserve of metal for forming the toesupport on the horseshoe, without diminishing the strength of the shoe-plate, as is the case where the toe-support is formed by gouging out the metal to form it, as is commonly the way of making horseshoes; also, on the face of the die-roll O, and circumferentially of it, is formed, at each side of the toe-support ing reserve of metal, nail-head countersinks J, having their inner edges perpendicular, and beveling oft' outward and downward. The object of this formation is to throw thc metal raised by the countersinks outward, so as to strengthen the outer edges of the shoe when formed, and thus cover the heads ofthe nails, and prevent their being rapidly worn oil' or breakin gV off, as is the case Where the heads or' nails are not well protected. The shape of the die-roll O is an oblong oval-that is, with curvilinear ends, and llattened sides. The object ot' making the roll of this shape is to form the blank of metal with an increased thickness of metal at the heel of the shoe, and thus strengthen it, not only for making a strong and solid heel-calk, but at the same time greatly increase the strength of the shoe at a point most liable to wear out.

Having now described my invention, I will proceed to set forth what I claim, and desire to secure by Letters Patent of the United States:

My improvement in machines for rolling blanks for horseshoes in continuous bars ot' metal, the oblong ovalshaped die-rodO, made with cavities H, for forming the toe-clips, in combination with the anvil-roll B, arranged and operating for the purposes and in the manner set forth.

JACOB RUSSELL.
