Abstract
576,061. Latches. YOUNG, L. W. Nov. 12, 1943. No. 18884. [Class 44] A swinging latch 16 rotates on a vertical spindle 14 and engages a bolt 22 fixed to a plate 24. A swinging locking member 30 is secured to the actuating bar 38 of a pin tumbler lock 42 and engages a shoulder 28 on the latch to lock it in the engaged position. In a modification shown in Fig. 3, the sliding locking member 31 is loaded by a spring 50 and is withdrawn by a cam 58 attached to the actuating bar 56. The cam 58 may be arranged so that on reverse rotation it engages a projection on the member 31 to deadlock the member. The locking member 31 may also be actuated by a cam 66 connected to a handle 62. In another modification, the end of the pintumbler lock cylinder is cut away, the projection forming a locking member for the latch. The Provisional Specification describes also an arrangement in which recesses in the edge of the latch co-operate with tumblers in a fixed part and a key is inserted in a slot in the fixed part. In another arrangement the latch is mounted on a horizontal axis and arranged to swing away from the bolt under the action of gravity. A further modification is described in which the latch has a notch engaged by a notched disc released by a key.
