Abstract
583,610. Handcuffs. PEERLESS HANDCUFF CO. Nov. 7, 1944, No. 21866. Convention date, Feb. 16. [Class 44] Picking of the lock of a handcuff of the kind described in Specification 372,619, by inserting a blade between the detent and ratchet is made difficult by providing a rectangular projection 16, Fig. 11, on the end tooth of the pawl and slotting the teeth of the ratchet to accommodate the projection ; the slot may extend to the base of the teeth or it may be shallower than the teeth, as shown in Fig. 8, to avoid undue weakening of the ratchet. The sides of the ratchet are grooved to receive projections on the co-operating casing to prevent distortion of the ratchet arm between its pivot and the lock.
