Abstract
222,290. Chatwood Safe Co., Ltd., and Bruckshaw, H. S. Aug. 25, 1923. Keys for looks.-A workholder for use in machining keys for locks comprises an annular frame a in which is rotatably mounted a disc i slotted at the centre to accommodate a block j adjustable in the slot by means of an eccentric b and a handle k, the latter being locked in any adjusted position by a spring plunger l. The key q to be cut is gripped in the block j by a jaw r actuated by a wedge and screw s and is supported by a bracket p. In operation, the block is adjusted in relation to a stationary cutter c for each ward, the disc, guided by side plates n, is oscillated during cutting in the frame a by means of a hand-lever o, and the frame is then advanced by a rack and pinion to cut the next word. The Provisional Specification describes a cam feed in place of the rack and pinion.
