Ganging of buffing wheels

摘要

A ganged buffing wheel assembly driven by a shaft having keys. The assembly is formed of a plurality of axially coextensive cartridges keyed to the shaft. The cartridges are of light weight such that they can be manipulated by a workman without injury to himself. Each cartridge, typically, includes a sleeve of pressed paper with keyways of white pine on its inner surface and with buff sections separated by spacers of pressed paper on its outer surface. The keyways extend along the whole length of each sleeve so as to be engaged by the keys on the shaft along a large area of minimized stress. In assembling a cartridge, the buff sections are stacked on the sleeve supported on a spacer at one end which is secured to the shaft. The stack is compressed with adhesive between each buff section and the spacers on each side and in the compressed state secured to each other and to the sleeve and anchored through the spacer at the other end. The cartridges are of low cost so that they can be discarded when the buff sections are worn.
