MOUNTING FOR ABRASIVE DISC

摘要

Mounting for an abrasive disc for quickly mounting the disc on a wheel adapted for attachment to a power operated spindle or arbor and without the use of tools, or removing the disc from the wheel by a reversal of the manipulation of attaching. The mounting includes a retainer to which the disc is secured and which embodies a clamping flange overlying the abrasive surface in the marginal region of a central aperture, and an extension disposed through the aperture and keyable to a stud threaded in the hub of the wheel. The stud can be drawn up within the hub by relative rotation of disc and hub to compress the disc between the flange and the hub.
