Abstract

1,213,689. Lift cage gate lock mechanisms. A.C.E. MACHINERY Ltd. 25 Nov., 1969 [9 Dec., 1968], No. 58406/68. Heading B8L. When the cage of a hoist is not opposite a landing, the gate 28, Fig. 3, cannot be opened because pivotal movement of a latch 3 about a pin 2 by a handle 4 is prevented by a spring- loaded lever 7 which abuts a stop 27. The lever 7 is urged into the position shown by a spring 18, Fig. 2. When the cage is opposite a landing, a wheel 10 abuts a cam 29, Fig. 4, and further rotation of the handle 4 in an anticlockwise direction causes the lever 7 to be pivoted about a pin 6 to the position shown in Fig. 5 in which it is clear of the stop 27, thus allowing the latch to release the gate.
