Abstract: A vacuum dust extraction apparatus for a percussive air tool contains and extracts workplace dust created by the impacting action of the air tool's implement. The apparatus includes a clamshell adapter constructed as two halves that are oppositely disposed about the air tool's retainer, and joined to enclose the retainer, and a tubular dust bellows fastened to the outboard end of the joined clamshell halves. The clamshell adaptor includes an integral exhaust port, and an industrial vacuum coupled to the exhaust port via a flexible suction/vacuum hose creates suction in the bellows for extracting airborne dust created by percussive action of the implement on a workpiece. Suction loss through the clamshell adaptor is minimized by a sealing element that bridges a gap between the interior periphery of the clamshell adaptor and the exterior periphery of the air tool's retainer.

Abstract: A spindle locking apparatus for power tools having a spindle mounted for rotation within a tubular housing. The locking apparatus includes a locking sleeve disposed between the spindle and its tubular housing, a locking collar surrounding the tubular housing radially outboard of the locking sleeve, and a set of drive pins mechanically coupling the locking collar to the locking sleeve through axial slots in the tubular collar.
