Abstract
An annular composite washer assembly provides a 'soft' mount for a tool element subassembly mounted on the threaded output spindle of a portable grinder or other power tool. The composite washer includes a pair of flat annular washers and a molded body therebetween. The body has integrally-molded inner and outer annular bands joined integrally with the inner and outer diameters of the respective washers. A first pair of blind axial pockets, diametrically opposed to one another, extends through the first washer and the body and terminates at the second washer. A second pair of blind axial pockets, diametrically opposed to one another and shifted circumferentially with respect to the first pair of blind axial pockets (preferably by ninety degrees) extends through the second washer, through the body, and terminates at the first washer. A second embodiment includes a first and second set of three equidistantly circumferentially spaced pockets, one set formed through the first washer, and the other set formed through the second washer. The pockets formed through the second washer are shifted circumferentially by approximately 60.degree. with respect to the respective pockets formed through the first washer.
