Abstract
An adapter (11) is of channel shape, having longitudinal projections (25) at its respective sides for engagement with undercut grooves (24) in a face of a casing of a powered grinding tool (10) with which the adapter is intended to be fitted to sharpened chisels or other planar blades, in use, by means of a grinding wheel (20) of the tool. The adapter has an angularly adjustable guide plate (63) which carrier a slidable plate (70) having magnetic means (71a) for holding an attracted blade of an implement to be sharpened, the angle of the guide plate (63) causing the blade to be correctly sharpened by the wheel (20), in use, as the plate (70) is reciprocated across the wheel with the blade held correctly thereon.
Claims10
An adapter for releasable engagement with a powered grinding tool including support means, a motor mounted within said support means and adapted to be driven by power supply means, a rotatable shaft drivable by the motor, and a rotatable grinding wheel to which drive is transmitted from said shaft, the adapter having engagement means for it to be secured in releasable snap-fit engagement to said support means at a work station of the tool and to be removed therefrom subsequently, the adapter defining a location which, when the adapter is secured to said tool at said work station provides for correct positioning between part of an implement at said location and said grinding wheel for said part to be worked by the wheel when it is driven, said adapter comprising a lower portion of generally channel shape having spaced sides and there being said engagement means at said sides respectively for securing said adapter to said casing of the tool to retain the adapter at said work station against lateral movement, and said engagement means at its sides are projections for engagement with complementary undercut slots at the casing.
