Abstract

156,936. Igranic Electric Co., Ltd., and Mackley, A. H. Oct. 24, 1919. Lift cages and doors, locking and unlocking.- A lift gate is provided with a mechanical lock which depends for its release upon the position of the lift, an electromagnetic lock which is released when the operating-circuit of the lift is opened, and a switch which permits the operation of the lift only when the gate is closed. The latch 4 is held in locking position by a pivoted catch 1, a part 2 of which forms the armature of an electromagnet 3. The opening and closing of the circuit of the magnet 3 shuts off or supplies current for the operation of the lift and is effected by the latch 4. The switch is pivoted at 11 and has an arm 9 carrying a contact 8, and an arm 12 kept by a spring 10 in the path of the latch. A cam 15 mounted on a spindle 14 prevents movement of the armature 2 away from the magnet until the spindle is turned by the engagement of the roller 17 with a member on the lift.
