Abstract
19,917. Harcourt, E. G. Sept. 15. Electric-bell pushes.-In an electric-bell push, specially adapted for use on tramcars, the dome or detachable part of the push is locked to the attachment socket ring by means of one of the screws used for fixing the ring in position. The dome a, Fig. 2, is recessed at a point b such that, when the dome is screwed home, the notch will fall into alignment with one of the fixing-screw holes in the socket ring c. The screw d is not inserted until the dome has been screwed home. The front . portion a<1>, Fig. 3, of the dome may be prolonged to protect the finger-piece e, which is provided with a rubber washer f to keep out the rain.
