Abstract

488,251. Door - operating appliances. HERBERT, Ltd., A., LLOYD, A. H., and JINMAN, C. H. Dec. 16, 1937, No. 34813. [Class 65 (i)] Sliding doors 11, 12 which are biassed towards closing as by weighted cords 23a, 23b are opened by a reversible electric motor 17 driving an endless cable &c. 19 carrying abutments 22 adapted to engage brackets 21 on the door. When the doors are fully open, a limit switch OLS stops the motor, and the doors are held open by the motor or its transmission against the closing bias. The doors are closed by reversing the motor and allowing the bias to operate. If one of the doors has a wicket gate 25, a switch WS thereon prevents closure of the motor circuit if the wicket is open. The doors may be suspended from an overhead rail by rollers 24. A time-lag device may be used to cause the motor to operate for closing after the doors have been open a certain time. When the doors are closed, a limit switch CLS cuts off current. The motor circuit may be controlled by ground abutments operated by a vehicle.
