BUFFINGWWHEEL.

SPECIFICATION forming part of Letters Patent No. 306,463, dated October 14:, 1884.

Application filed August 1l, 1883.

To a/ZZ whom t may concern:

Beit known that I, ROBERT BINNS, of South W'indhannin the county of Vindham and State of Connecticut, have invented certain new and useful Improvements in BuflingVheels; and I do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

Figure l is a plan view of my buffing-wheel, the line of stitching being indicated by conventional broken lines. Fig. 2 is a view in cross-section of one form of my completed buff ing-wheel formed of textile fabric or filamentous material; and Fig. 3 is a view similar to Fig. l, but with the outer layer of fabric removed to show the scraps or pieces of which it may be made.

Heretofore buffwheels have been made of pieces of textile, fibrous, and other material united by sewing through and through the mass of superposed pieces in radial lines or concentric circles. In using such wheels the workmen open the periphery of the wheel to loosen the pieces, and as the wheel is worn, its periphery being made most dense by and in the lines of stitching, it follows that there will be a constant variation and inequality rin the density and effectiveness of the active surface of the wheel. This defect produces bad work. Furthermore, with the radial stitching, as the wheel wears the stitclrthreads whip out and cut the workmans hands, and this defect is, if anything, aggravated by sewing in concentric circles. Now, in attempts to overcome these defects, I have found that by sewing the material of the wheel together by stitches arranged in a spiral line continuous from the rim of the wheel. to its center I get awheel of practically (No model.)

uniform density throughout, and in which the whipping out ofthe stitch es is very materially, if not altogether, removed.

lMy invention therefore consists of a buffwheel of textile or other fabric or material sewed together in superposed pieces by stitches extending spirally from rim to center, all as hereinafter particularly set forth and claimed. In making my wheel I take first a layer or disk, a, of textile fabric, as cotton, and upon it place a given quantity of rags, scraps, or fragments of fabric or filamentous material, b, at random, taking care only to place the pieces in comparatively even layers when textile materials are used, and upon this mass I lay a second outer whole layer or disk, c, and compress the whole mass, and secure it by one or more spiral lines of stitching, d, extending from the rim to the center, the stitches going through and through the said mass. These thread-stitches, so arranged, serve to hold the mass compact from the center to the very edge 6- ofthe wheelthus preserving a circular periphery, its equal density, and insuring its wea-rA ing down evenly to the clamps attaching it to its driver. The Woof-threads of the pieces of cloth will extend in every direction, and, as distinguished from a wheel having its layers of whole cloth in which the woof-threads will almost unavoidably run parallel in the several layers, my wheel will to this extent be further enhanced in its tendency to wear down evenly. After the mass is sewed it is cut to shape and provided with an arbor hole or hub.

A bufng-wheel composed of rags, scraps of textile fabric, filamentous material, or the like, 8o compressed and united by one or more spiral lines of stitching, substantially as described.

ROBERT BINNS.
