Abstract
20,044. Bois, J. Sept. 8. Locks, key; keys; latches.-Relates to the lock described in Specification No. 18,586, A.D. 1905. The bolt 7 is operated by the fixed bit 20 of the key by means of a toothed camdisk 18 and pivoted lever 10, after the levers have been set, as described in the above-mentioned Specification, and the sliding bar 3 has been moved by the key to disengage the end 6 of the bell-crank 4 from a notch in the bolt. The tumbler 16 is depressed when the bolt is shot by a pin on the bolt engaging the sinuous slot 15 therein. The key bits 19, 20 are placed in a rectangular slot in the barrel 27 of the key and are retained therein by means of an internal longitudinal rib 28, engaging grooves in the bits, and the set-screw 29. In withdrawing the bolt, the key also withdraws the latch through the lever 25 pivoted on the disk 18. In Fig. 3 is shown a modification, in which the bolt is operated directly by the key and is provided with the spring locking- tumbler 31.
