\VILLIAM ALBERT STONE, OF EDDYVILLE, ILLINOIS.

HOOP-SHAVING MACHINE.

SPECIFICATION forming part of Letters Patent No. 352,496, dated November 9, 1886.

Application filed March 24, 1856. Serial No. 196,391. (No model To all whom it may concern.-

Be it known that I, WILLIAM ALBERT STONE, of Eddyville, in the county of Pope and State of Illinois,have invented certain new and useful Improvements in Hoop-Shaving Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this speciflcation.

My invention relates to an improvement in hoop-shaving machines; and it consists in the combination of a series of rotating knives, a stationary knife,suitable guides through which the hoop is passed, a fluted roller, and suitable cuffs, which are placed under each of the re volving knives, the stationary knife, the fluted roller, and a single cuff which is placed upon a shaft by itself, above the level of the other ones, for the purpose of breaking the hoop, all of which will be more fully described hereinafter.

The object of my invention is to provide a machine in which the hoops can be rapidly shaved and broken while passing once through the machine, and in which the parts are few, simple, and not liable to get out of order.

Figure 1 is a vertical section taken through the center of the machine. Figs. 2 and 3 are end views of the same. Fig. 4is a side elevation.

A represents a suitable frame-work of any suitable construction. The driving-shaft B passes horizontally through the machine to one side of its center, and is provided with a fly-wheel, O, at one end and a pinion, D, at the other. This pinionD meshes with the two large wheels E, which operate the cylindrical knives and curved roller for pulling the hoop through the machine. Upon the same end of this operating-shaft as the pinion are secured both a pulley, G, and a crank, H, so as to enable this machine to be run by an ordinary thrashing-engine, or any other suitable power that may be applied thereto.

The knives I are secured between the two heads J on the shaft K, and these knives are made rounding on their outer and concaved on their inner sides. The sharpening of these knives is done on the inside, so as to keep the cutting-edge the same distance from the gage until the knives are entirely worn out. The

knives score and shave the hoops at the same time that they force each hoop ahead, and keep crooks and bends out of the' hoop while it passes through under the stationary knife. Under these revolving knives, the stationary knife, and the fluted roller are placed cuffs L, which are adjustable upon their shafts, and which are fluted and convexed on their inner ends, as shown. One of these cuffs in each instance is stationary on its shaft, while the other is made adjustable in relation to it, for the purpose of lowering or raising the hoop as it passes through the machine, and thus increasing or decreasing the thickness to which it is to be out. When the movable cuff is moved away from the stationary one, the hoop will sink deeper between them, and thus the knives will not cut away as large a portion of it, and when the cuffs are brought nearer together the hoop is correspondingly raised, so that a larger portion of it will be cut away. In this manner the thickness of the hoop is regulated at will.

Just beyond the revolving knives is placed a tapering guide, M, which is largest at the end next to the knives, and through which the hoop passes, so as to be guided directly into position to be operated upon by thestationary knife N. This knife N is held in suitable guides, O, and secured in any position by means of set-screws P Q. The set-screw P bears against the rear edge of the knife, and serves to force it forward, while the set-screws Q-serve to readily clamp the knife in any desired position. This knife N is placed on a level, but has its edge on an angle to the hoop which is passing over the cuff belowit, and serves to shave the face of the hoop which has already been acted upon by the cylindrical knives. The edge of the knife is set on an angle,so as to cause it to out easier and smoother than it would do if placed upon asquare.

Just beyond the stationary knife is placed a second funnelshaped guide, B, into which the end of the hoop passes, so as to guide it directly to the fluted roller S upon the shaft T,

chine depends upon the rapidity at which the parts are driven and the hoops are fed in.

Having thus describe my invention, I

claim- I 1. The combination of the series of revolving knives placed at the end of the machine where the hoop enters, a guide for directing the movement of the hoop and placed between the cylindrical knives and the stationary knife, and the stationary knife and the fluted roller, the fluted roller for drawing the hoop through" the machine, and cutfs which are placed under the revolving knives, the stationary knife, and the fluted roller, substan-' tially as shown and described.

2. The combination of the revolving knives placed at the end of the machine where the hoop enters, a suitable guide placed between the revolving knives and the stationary knife, the stationary knife placed between the guides through which the hoop passes from the machine, and cufl's which are placed upon a separateshaft and at a higher elevation on the machine than the other cuffs, for the purpose of breaking the hoop before it-lea-ves the machine, substantially as set forth.

.In testimony whereof I aflix my signature in presence of two witnesses.
