IMPROVEMENT lN BUFFlNG-WHEELS FOR FINISHING BOOTS AND SHOES.

Specification forming part of" Letters Patent No. 203,265, dated May 7, 1878; application filed November 26, 1877.

To all whom it may concern:

Be it known that I, CHARLES C. GREEN, of the city and county of Worcester, Common wealth of Massachusetts, have invented 'a new and useful Improvement in Buffing-Wheels for Buffing the Bottoms of Boots and Shoes, and for other purposes, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l is a perspective view of my said improved buffing-wheel placed on arbor C, which is adjusted in standards B B of frame A, to turn in the bearings. Fig. 2 represents a half-section of the wheel, showing my slotted curve-spring I fastened longitudinally to the inner edge, and my cam-shaft, having hooks G formed on it, adapted to and placed in said spring. Fig. 3 represents my camshaft and the hooks thereon. Fig. 4 represents an end view of said spring.

The object of my invention is to furnish a device by which the sand-paper or emerycloth can be easily and quickly placed around and secured to or removed from the wheel; and it consists in making a wheel of either wood or metal of two sectional pieces, in one of which a groove or space is made near the edge, extending from end to end. The slotted curve-spring is fastened to the inner edge of the other sectional piece, as shown in Fig. 2. In this slotted curve-spring I, I place my camshaft, with hooks G adapted to and operated in said slotted spring. The sections of the Wheel are brought together and secured with plates L at the ends, leaving a narrow opening, F F. At the rim there should be room for the spring to have action in the groove or space before mentioned. The cam shaft is held in position with the plates'L at each end, which are fastened with bolts or screws. The end 0 of the cam-shaft is squared for a wrench with which to turn it. Pins M and N are placed one in the cam-shaft and the other in plate L, to set the hooks in position for introducing the ends of the sand-paper or emerycloth into the narrow opening F F.

The wheel may be covered preparatory for the sand-paper in the ordinary way, with felt cloth or other suitable material.

It will be seen that with this device, by placing the sand-paper or emery-cloth around the cylinder, and tucking the ends into the narrow opening F, then, with the wrench, turning the cam-shaft hooks down, they will fasten through the ends of the paper or cloth into the slots P, and thus they are together drawn between the spring and cam-shaft, thereby holding the sand-paper securely on the roll, presenting an even surface on the outside for buffing or polishin g purposes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The improved buffing-wheel having the slotted curved spring I, and the cam-shaft, with hooks G adapted to and operated in said slotted spring, substantially as and for the purpose herein shown and described.

CHARLES C. GREEN.
