Abstract

635,971. Door-operating devices. NORBALLE, S. G. July 9, 1946, Nos. 20483 and 20484. Convention dates, March 9, 1945 and Jan. 16, 1946. [Class 65 (i)] In a door closing and check device in which the operating spindle 1 is coupled by a chain 6 to a hydraulic brake piston 4 loaded by a spring 5 the casing 2 is provided with alternative bearings 20 for the end of the spindle and the cover 10 which carries a fluid-tight bearing for the spindle is adapted for reversal to suit either of the bearings 20. Recesses 17 in the cylinder 3 and passages 19 in the piston render the brake inoperative at the bottom of the cylinder. In a modification in addition to the byepass valve 16 further valves are provided at spaced locations along the passage 15.
