Abstract

163,836. Woolliscroft, J. H. March 6, 1920. Checks.-A pneumatic door check consists of a cylinder 1, with an air valve 10, mounted on one member of the door, in which slides a rubber ball 9 held in a piston 8 with a rod 3 surrounded by a volute spring 13 in order to allow angular motion of the rod relative to the axis of the cylinder. The end of the rod has a buffer 5 and a collar 6 which co-operates with a clip 7 fixed on the other door member. On opening the door, the piston is withdrawn to the end of its stroke by the clip 7 assisted by a spring 11, whereupon the rod is slightly rocked to free the collar, the rod being restored to its central position by the volute spring.
