Abstract
190,382. Dyson, F. Jan. 20, 1922. Push-button switches.-A switch for controlling signalling or brake-applying apparatus on a train for operation by a track contact working in conjunction with a semaphore consists essentially of a plate of insulating material b, preferably glass, mounted in a frame B adapted to slide in a frame A so as to pass clear of a push-button switch C, which then completes a circuit through contacts c, c<1>. The frame B is cut away at b<1> in order to clear the switch C. A lever D pivoted to the frame A, and to the slide B by means of a slot d<2> and pin d<3>, may be used to operate the slide by engagement of its lower end with a track contact. The lever may be held in either of three positions by means of a spring-pressed ball engaging recesses a<1> in the frame. The Provisional Specification also states that the frame may be moved directly by the track contact and may be held in the " off " position by copper wires which are broken when the frame is moved.
