Abstract

222,635. Chatwood Safe Co., Ltd., and Brucltshaw, H. S. Aug. 25, 1923. Locks.-A work-holder for use in machining the levers of locks comprises a carrier h mounted by means of a pivot j on a lever c which is pivoted at b and is angularly adjustable by means of an eccentric d operated by a handle e. A spring- pressed plunger f, coacting with a series of apertures in a plate g, locks the eccentric in any position. A series of similar superimposed locklevers i is located on the carrier by a pin m and a cam n which is adjusted to suit the height of the step on the key adapted to cooperate with the levers and is locked by a spring plunger o. The levers are then clamped by nuts q, and the carrier is oscillated about the pivot j by a hand-lever k so that a fixed milling-cutter may operate on the belly of the levers. A jig having an aperture to receive the cutter may be temporarily secured to the base a to enable the device to be positioned on the machine table.
