BUSHING FOR BUFFING-WHEELS.

SPECIFICATION formingpart of Letters Patent No. 716,325, dated December 16, 1902.

Application filed September 30. 1902. Serial No. 125,422. (No model.)

`State of Connecticut, have invented a new and usefullmprovementin Bushings forBufting-Wheels; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereonto bea full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a perspective view of a bushing having a bufli ng-wheel constructed in accordance with rnyinvention; Fig. 2, a vertical sectional view through the bushing and a portion of the wheel enlarged; Fig. 3, a perspective View of the inside of one of the members of the bushing; Fig. 4, a perspective view of the frictional bushing detached;'Fig. 5, a perspective view of the clamping-washer; Fig. 6, a perspective view of the clamping-nut; Fig. 7, a perspective view of the bushingwasher and nut in their connected positions.

This invention relates to an improvement in bushings for bufing-wheels, and particularly to wheels which are made fromdisks of cloth, leather, or other suitable material, to the surface of which buftng-rouge or other abrading or polishing substances are applied. In wheels of this character, which are to be mounted upon `a tapered spindle, the center of the wheel or bushing is formed from leather or substance of like character which will hold the wheel dn the spindle. These bushings are glued in the center of the wheel and become worn before the face of the wheel is destroyed, and it has been necessary to cut these bushings out and replace them with other bushings; but more or less difficulty is experiencedin arranging the new bushings concentric with the wheel.

The object of this invention is to provide a bushing which may be readily inserted through and removed from a wheel, which bushing shall contain a core of leather or other suitable material, adapting the wheel y to be placed upon a tapered spindle.

My improvement also provides a construction which permits the same wheel to be applied toa threadedspindle; andthe invention consists in the construction as hereinafter described, and particularly recited in the claims.

The batting-wheel Ais made up of disks of cloth, leather, or other suitable material in the usual manner. Through the wheel is a central opening B, through which my irnproved bushing extends. This bushing is formed in two parts C, each forming a half of the bushing and each consisting of a body D, a flange E, and a reduced outer end F, which forms a shoulder G. The reduced end F is provided with external threads II and internal threads I. The body is formed with a tapered recess J, in which is an annular rib K and a longitudinal rib L. A frictional bushing M, of leather or other suitable material, tapering longitudinally and corresponding in size to the chambers .land formed with a longitudinal hole N, is placed in the chamberJ and the two parts C pressed together to inclose it, the ribs K and L entering the frictional bushing M, so as to lock it in position. Preferably a washer O will then be placed over the body D and against the inner face of the ange E, so as to hold the two parts together. The bushing is then inserted through the hole B in the center ofthe wheel and a nut P applied over the reduced end F and against the shoulder G, this nutforming a liange corresponding substantially in diameter to the iiange R at the other side of the bushing. This nut not only serves to clamp the wheel but also interlocks the two members of the bushing together. The threads I of the two members provide means for mounting the wheel upon a threaded spindle, While the frictional bushing M adapts the wheel to be mounted upon a tapered spindle. When this frictional bushing becomes worn, the nut P may be readily removed, permitting the bushing to be withdrawn from the wheel, the parts separated, and a new frictional bushing inserted and the device replaced. This assures that the bushing shall be concentric in the wheel and can be applied in a few moments and avoid the necessity of waiting for glue to dry, as is the case when the bushing is glued in the wheel.

Having fully described my invention, what I claim as new, and desire to secu re byLetters Patent, is
