O. H. PERKINS. MACHINE FOR MAKINGHORSESHOES.

No. 44,840. Patented 001;: 25, 1864.

" UNITED STATES PATENT FFICE.

CHARLES H. PERKINS, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO THE UNION HORSESHOE COMPANY, OF SAME PLACE.

MACHINE FOR MAKING HORSESHOES.

Specification forming part of Letters Patent No. 44,840, dated October 25, 1864.

To aZZ whom it may concern;

Beit known that 1, CHARLES H. PERKINS, of the city and county of Providence, in the State of Rhode Island, have invented a new and useful Machine for Thickening the Ends of Horseshoe-Blanks; and I do hereby declare that the following specification, taken in connection with the drawing making a part of the same, is a full, clear, and exact description. thereof.

The machine is fully represented in the perspective drawing. I

I design to make the apparatus an attachment to the machine for making horseshoes fo r which Letters Patent, numbered 1,641 were granted to me on the 25th day of June, A. D. 1861; but the same can be used, if desired, as a separate and independent machine.

A horseshoe should be made with the metal at the heels considerably thicker than at the too. In shoes which are made by hand this is effected by npsetting the shoe by blows upon the ends, either before or after it has been bent into shape, the bar being held at the time in a vise at the point where it is desired the increased 'thickness should con1- mence.

In the accompanying drawing, A represents a shaft which, when the apparatus is attached to my machine for making shoes referred to, will be the main cam-shaft.

v B represents the platform or bed upon which the parts are mounted.

C is a stationary die with a straight face, and c is a movable one with its face cutaway or made concave midway between the extremities, so as to compress apiece of metal placed between the two dies more at the ends than at the middle.

The die E is furnished with a shank 0.,which is fitted to slide between the guides b b. A

spring (not shown in the drawing) located underneath the shank, with one end fixed in the bed 13 and the other let into a mortise in the shank, or otherwise arranged for the purpose, tends to keep the back of the die 0 bearing against the guides b b. V

The revolving shaft A is connect-ed with the movable die 0 by means of the pawl D, attached bya strap to an eccentric on the shaft, whereby a reciprocating motion is imparted to the pawl as the shaft revolves. Upon the under sideof the pawl is placed a flexible spring-piece s, the oflice of which is, when the pawl is not acting to work the movable die, to support the pawl and enable it to ride on the back of the shank a, so as to clear a shoulder c, against which it is designed that the end of the pawl shall press when it is desired to operate the die.

The bar of iron of which the shoe is to be made is taken from the furnace and placed upon the bed i5 between the faces of the two dies 0 and O". The attendant with his hand then depresses the pawl D by the aid of the handle E. This causes the movable die to be thrown forward, and, squeezing the bar at the ends against the fixed die G, thickens itat the parts which will form the heels of the shoe. As the pawl moves backward, the die 0 is carried back by the spring above described, and at the same time the spring-piece s raises the pawl clear of the should er 0. The bar is then pushed along the platform to that part of the machine where the operations of bending, creasing, and plating are to be performed upon it, as described in the patents before referred to. i,

What I claim as my invention, and desire to secure by Letters Patent, is

The method of thickening the ends of horse shoeblauks by the combination of the dies 0 and C, when constructed and operated in the manner substantially as described, for the purpose specified;

CHARLES H. PERKINS.
