ABSTRACT:
A self-contained mount, for a spindle-driven rotary abrasive tool or the like, able to compensate for slight non-concentricity of the threading on the end of a drive spindle for the rotary tool. The mount includes an internally threaded cylindrical sleeve with an outside diameter small enough to be inserted into a longitudinal axial bore in such tool, and a retaining ring to maintain the sleeve fixed longitudinally therein while permitting it to adjust its position relative to the rotational axis, if necessary, upon being screwed onto a threaded end portion of the spindle, while supporting the tool coaxially therewith. In a modified version, a backup washer is interposed between the retaining ring and the end of the tool; and in a refinement of such modification a supplementary washer is interposed, with the abutting surfaces of the washer and the sleeve chamfered to fit together so they can adjust in relative position even more readily, to accommodate axial misalignment of the sleeve by the threaded part of the spindle. The preferred embodiment of such refinement utilizes a spherically concave face on the backup washer and a corresponding convex face on the adjacent end of the mounting sleeve, an optimal arrangement for permitting self-adjustment of the sleeve position.
