TRIOT OF COLUMBIA.
ROLL FOR PREPARING HORSESHOE-BLANKS.
SPECIFICATION forming part of Letters Patent No. 434,838 dated August 19, 1890. Application filed December 28, 1889. Serial r5. 335,262. No model.)
To all whom, it may concern:
Be it known that I, ZACHARIAH V. PURDY, a citizen of the United States, residing at Vienna, in the county of Fairfax and State of 5 Virginia, have invented certain new and useful Improvements in Rolls for Preparing HorseshoeBlanks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable I others skilled in the art to which it appertains to make and use the same.
In the manufacture of horseshoes by machinery the shoes are usually formed from blanks previously prepared by grooving and I punching. The blanks are prepared by passing the bar between rolls provided with circumferential ribs for forming the grooves, and with projections or teeth which act as punches to form the nail-holes. As heretofore constructed these ribs and punches were formed on the rolls as integral parts thereof, and therefore when these parts were worn out or broken it became necessary to replace the entire roll with a new one, which involved not only a large expense but a great deal of time and trouble.
Now the object of my invention is to avoid the expense involved in the replacing or renewal of the entire roll in the event of break- .ages, &c., by making the working parts of the roll-that is, the grooving flanges or ribs and the punchesseparate from the body of the roll in order that these parts alone when worn out or broken (and they are the only parts subject to wear or liable to be broken) may be renewed or replaced Without renewing or replacing the entire roll.
In the accompanying drawings, which illustrate my invention and form a part of this specificatiomhigure 1 represents in partlysectional elevation a pair of rolls mounted ina suitable frame. Fig. 2 is an elevation of the intermeshing gears on the ends of the rolls. Fig. 3 is an elevation of the removable collar on which are formed the groovingribs, and which carries the removable punches for forming the nail-holes. Fig. 4 is an enlarged perspective of one of the punches, and Fig. 5 is a view of a section of .a bar after being rolled into blanks.
A A designate the two rolls, which are mounted in a suitable frame B B, and are provided at one end with intermeshing gears O O, by which they are caused to rotate together. One of the rolls (the lower one, as shown in the drawings) has acircumferential groove or channel a of suitable width and depth to receive the bar to be rolled into'-' groove a in the other roll and receives a collar D, which snugly fits thereon. This collar is of the same or substantially the same diameter as the larger part of the roll, and its circumference is equal to twice the length of a shoe-blank, so that in each revolution of the rolls two blanks will be rolled. Shoes are usually formed with four nail-holes at each side, and the space between the first nailholes at each side of the toe is about equal to one-half the distance of the last holes from the heels, and the parts of the shoe in which the holes are formed are grooved. The grooving is eifected by circumferential ribs d on the periphery of the collar ,D.
The collar D has formed in it transverse dovetailed notches or grooves d to receive and hold similarly-shaped blocks 1, upon the outer ends of which are formed projecting teeth d', which act as punches to form nail-holes in the blanks.
In order to give the proper spacing between successive grooves and groups of nail-holes to leave the required blank spaces at the heels and toes, the collar D is provided with two ribs d of proper length, and with two series of punches d on opposite sides of an imaginary line through the center, as indicated by the broken line in Fig. 3. Supposing the roll to be revolving in the direction indicated by the arrow in Fig. 3, the rolling of the first blank will begin at the point 0, and said blank will be formed by the upper half of the collar. (marked 2 4,) the second blank by the lower half, and so 011. The blanks will be formed as represented in Fig. 5, the transverse broken lines in said figure designating the lengths of the blanks and the dividing-lines between the same.
The bars so rolled and formed into shoeblanks are ready to be fed into a shoe-forming machine invented by me, which forms the subject of an application for Letters Patent signed and executed by me on the 16th day of November, and filed herewith, which machine severs the blanks from each other as they are successively fed in.
The collar D is prevented from turning on the roll by dowel-pins e e, which connect it with the larger part of the roll, and it is held in place against the shoulder by a sleeve F, which fits the reduced part of the roll and is keyed upagainst the collar by a transverse key f, which passes through the sleeve and roll.
In the event of the breaking of any of the punches d or when they are Worn out, the parts are unkeyed and separated, the blocks d are taken out and replaced by new ones, I
which may be effected in a brief space of time and at slight expense, when the roll will be as good as new.
Having now described my invention, I claim- 1. The combination, with the roll A, of a separate collar D, mounted thereon and hav-
