Abstract

271,610. Stell, S. April 13, 1926. Lift cages and doors, locking and unlocking. -A locking device for the doors of electrically operated lift cages &c. comprises an oscillating switch member having a plurality of engaging projections for the locking bolt and having contact elements engaging with a sliding movement. The cage door 20 carries a sliding bolt 7 with a projecting lug 7<a> adapted to engage the end 6<c> of an arm 6 pivotally mounted on a stud w in the lock box A and move the arm until its notch 6<b> engages a notched arm 8 on a shaft 9 operable in the usual way by a runner &c. on the cage. The lug 7<a> on the bolt is then held in the locking position by a projection 6<a> on the arm 6. The arm 6 is mounted on a boss 2<a> carrying a bridge piece 2 with electrically connected contacts 3 sliding over mating contacts 10 in the control circuit 10<d> of the lift. When the cage arrives at the landing the arm 8 is released and the bolt can be withdrawn, so rocking the bridge piece and breaking the electrical circuit. In a modification, the arm 6, Fig. 5, has a single arm a<2> instead of the bridge piece and the arm a<2> is adapted to slide between. a pair of spring contacts 10<h> in the control circuit.
