ABSTRACT:
An accessory for a hand drill which cooperates with the crank handle of the opening mechanism of a casement window. The accessory, when turned by the drill, facilitates turning of the crank handle and opening or closing of the window. The accessory includes a shaft which is intended to be gripped by the chuck or jaws of the hand drill in much the same manner that hand drills grip drill bits. A forwardly projecting crank handle-contacting head is provided which is adapted to slide over the crank handle. The head has a side opening with a pair of edges which push against one side of the crank handle in order to rotate the same. Preferably, the inside surface of the head of the accessory and the crank handle's contacting edges are rubber coated so that rotation of the accessory and its movement with respect to the crank handle will not mar the finish of the crank handle. In an alternate embodiment, the head can be adapted for rotation of the splines of the window turning mechanism exposed when the handle is fully removed. In yet another alternate embodiment, a head is provided which is adjustably configured to receive different sized crank handles.
