Abstract

20,444. Medway, M. T. Sept. 1. Lift doors, locking and unlocking.-In a combined electric switch and mechanical locking and unlocking device, the sliding lock bolt R and the frame are bevelled at Q', Q<2> respectively so as to co-operate with the pivoted catch G, which when the gate is closed, is secured by the bolt R and arm P, and presses on the pivoted contact arm C so as to complete the control circuit. On approaching a landing, the bowl M, which is displaced by an inclined surface on the cage, operates the arm N, shaft 0, and arm P, so as to release the bolt R. The catch G can then be raised by a projection K on the arm J, thereby breaking contact and, as the post I<1> is operated to open the gate, a pin S on the post I<2> engages the lug R and knocks up the catch, which remains in this position until the posts are separated to close the gate.
