IMPROVEMENTIN ROLLS FOR ROLLING HCRSESHOE-BLANK BARS.

Specication forming part of Letters Patent No. 159,426, dated February 2, 1875; application filed July 3l, 1874.

`To all whom it may concern:

Be it known that I, WILLIAM W. LEwIs, of

Cincinnati, in the county of Hamilton and State of Ohio, have invented certain Improvements in Horseshoe-Machines, of which the following is a specification: My invention relates to machinery for roll- 1ng horseshoe-blanks 5 and consists in the construction and arrangement of a pair of rolls for rolling horseshoe-blanks, one or both of which is grooved in such manner with reference to a creaser in the groove of one of them that the crease shall be oblique or'undercut inlthe shoe, and also that the blank shall be full and perfect, as will be more fully described hereinafter.

Figure lis a front View of arpair of rolls. Figs. 2 and 5 are sections, showing different forms of creasing devices; and Figs. 3, 4, and 6 are side views.

A B C D, Src., are grooves in one of the rolls, for forming the edges and treads of the horseshoes. The other roll has inclined faces B' C', &c., for forming the upper side of the shoe. In the grooves A B C, Src., are annular projections or creases a a a, for forming the crease in the shoe. The creasers, or more properly crease-liners, in grooves A and K, are mere shoulders, anddo little more than mark the line of the crease. Those in grooves B and H are somewhat deeper, and form a very slight crease in the bar. This line or crease may then be cut to the proper depth and proportions by passing the bar through a roll with creasers of greater diameter.

For the better illustration of my invention, I have shown in Fig. 1 grooves for forming a variety of differentshaped sh oesf that is, shoes for diiferent kinds of work. Each of the grooves is designed to operate on and form different-shaped blanks, but they all,with the exception of grooves A', H', and K', embody the essentials of my invention.

Heretofore two very serious objections to machine-made horseshoes have been that the creasing was coarse and clumsy, and was not at the proper angle to drive nails, in conformance with the natural requirements of a horses foot, and at the same time have the nail-heads wedge tightly into the crease.

These objections I overcome by making the faces B', 85e., which form the upper surface of the shoe, inclined to the axis of the roll, by which, as the creaser must revolve at right angles to the axis of the roll, I obtain a crease inclined to the upper surface of the shoe-that is, an undercut crease, and the degree of under-cut may be varied by varying the degree of inclination of the faces B', &c. The grooves A', H', and K' represent the face of the lower By having the creaser in the groove I am enabled to make many different forms of blanks, and especially I am enabled to make a shoe with a beveled outer edge, so that the horse will not cut or chafe his legs by awkward motions. The inner edge, also, may be beveled, thus making a lighter shoe, and throwing the horses weight more on the outer crust of his hoof.

In Figs. 2, 3, and 4, at a', is shown a break in the creaser, for forming the toe portion of the shoe, and at c is another break for the heel, with a small projection, c, to mark off the bar into lengths. This projection may be made larger, so as to cut the bar through,and the creaser may be provided with projections or punches for punching the nail-holes.

Another advantage incident to the use of a roll with inclined faces B' C', &c., is, that the direct pressure of the rolls comes on the heavy parts of the blanks, which are behind the crease, and they are perfectly formed, with clear and distinct edges. If the part in front of the crease came under the direct action of the'roll it would result that the iron would be all pressed away from that part, and we would have, instead of a properly-formed crease, a

mere right-angled or L-shaped depression or step at the edge of the bar.

I claim as my invention- 1. A pair of improved rolls for rolling horseshoe-blanks, of which one is grooved, and has a creaser in the groove, and the other has an inclined face opposite the ereaser in the groove rounded side, for producing a. horseshoe with of the first, for producing a blank with an una beveled or rounded edge, so that the horse dercut crease, &c., as described.

2. A pair of improved rolls for rolling horseshoe-blanks, of which one has a groove in it, with a beveled or rounded side and a creaser in the groove, and next to the beveled or Will not cut himself when he interferes.
