Abstract

756,974. Door-operating apparatus EXPRESS LIFT CO., Ltd., and HEPPELL, W. A. Jan. 18, 1955 [Jan. 25, 1954], No. 2215/54. Drawings to Specification. Class 65 (1).. A power-operated sliding door is provided with an inertia member which moves with it during closing and which actuates control means to stop the movement if the door is abnormally decelerated, for example by meeting an obstruction. The arrangement may be used in conjunction with a sensitive door edge device. In the form described a pendulum is mounted on a knife-edge bearing on a baseplate adjustably mounted on the door so that the pendulum normally rests against a stop during the closing of the door and moves away from this stop to actuate a switch if the door is subjected to deceleration of more than a predetermined value. Specification 756,975 is referred to.
