IMPROVED Moms: or MANUFACTURING Ton-CALI; BLANKS.

The Schedule referred to in-theae Letters Patent and making part of the same.

To all whom it may concern;

Be it known that I, ABRAM REESE, of McClure township, in the county of Allegheny, and State of Pennsylvania, have invented a new. and useful Improvement in the Manufacture of Toe-Oalks; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing, making a part of this specifica tion, in which- Figure 1 is a crosssection of a pair of rolls, properly gropved, collared, and notched, for rolling toe-calks or toe-calk bars;

Figure 2 is a perspective view of a bar with a raised edge, illustrating an intermediate step in the'process of rolling; p

Figure 3 shows, by a similar view, the shapeof the toe-call: bar; and

' Figure 4 is a like view of one of the toe-callis, cut from the finished bar.

- The nature of my invention consists in rolling toecalk bars, from which to make toecalks for horse-shoes, by first rolling a raised bead or. projection along the edge-of a bar of iron or steel, of properthickne'ss and depth, and then rolling down such bead or projection at intervals, so as to leave standingjthe spurs; by which more perfectly to weld the calk to the horse-shoe, and further, in the mode of cutting calks from such rolled bars.

To enable others skilled'in the art to make and us my invention, I will proceed to describe its mode of operation and manner of use.

I first take iron or steel bars, of the proper quality for the use .designed, and, by rolls suitably grooved, reduce them to the thickness required in toe-calks, and to a width a little in excess of such requirement; or I work the iron or steel into that shape and size direct from the bloom, pile, or billet.

Such bar I then pass throughbetween a pair of rolls,

so grooved as to reduce it'to the form substantially as shown in fig. 2, the excess of metal in the original bar, consequent on its excess of width, as above described, being sufiicient to form the head a, on the body b, of a v-shape, as shown, or of an oval form, or of such other regular or'irregular shape as will secure the same result.

v For the further .rolling' of the bar, I construct apair of rolls, collared, grooved, an dnotched, as in fig. 1.'

The bed f, housing g, set-screws h, and 'plummei blocks 1, are of the usual construction.

at and d are a pair of cylindrical metallic rolls, the

upper one, 11, having a collar, 0, of the breadth of 'the body I; of the bar. Such collar 0 plays into a groove, 0, in the lower roll. v

The distance from the face of the collarc to the bottom of the groove 0, at the point'of bite, isequal to the vertical depth of the calk-bars on (fig.3) to be bead a is then flattened, and rolled down into the body m of the calla-bar, except where it enters the notches or depressions In these the spurs nare formed, as already stated, and at such distances from each other that each calk, when the bar is cut into calks, shall have one ormore such spurs on its upper surface.

The bars, when thus rolled, are sold in that condi-' tion, as an article of merchandise, or cut up into calks' and then sold, ready to be heated and welded to the shoe.

As already intimated, I do not limit myself to any particular form for the bead (0, provided that it be deep enough, or raised high enough to givespurs nlof the required depth.

In cutting the calk-bars or into calks, I find it bet-l ter to make the division or cut through the middle of each spur n, so that thusI get a calk of the form shown in fig. 4, the spins-n being at the extremities of the body m of the calk, and each spur n being one-half of one of the spurs n, asrolled on the body m of the calk-ba-r. In this way I get a sharper spur than can be conveniently produced merely by rolling, and conr sequently one bywhich the calk can be more easily attached, and more perfectly welded to the shoe.

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

The mode ofmaking toe-calks, substantially as hereinbefore described.

In'testimony whereof, I, the said ABRAM RnEsE, have hereunto set my hand.
