Abstract

151,401. Biddle, W. H. July 11, 1919. Combined electrical and mechanical systems, automatic; track apparatus actuating signals other than on trains. - A signal-releasing mechanism mechanically connected to the signal arm and operated by a treadle depressed by a passing train to put the signal to danger is electrically reset to clear the signal, and contacts carried by the releasing-device control the circuits to apparatus in the rear to maintain the required number of signals at danger and reset them to clear when the train has passed ahead. The signal arm h is connected to a slide d which can 'be lifted by the treadle m, k to clear the lower slide e so that the signal is free to go to danger under gravity and move the slide d to the left. Contacts t' closed by the contact d<2> complete a circuit to a magnet x<1> of the signal at the rear, and that magnet draws the lever n clear of the lugs e<3> and allows the bar e of that signal to move to the left, and close contacts v<1> in the circuit of the magnet y<1> of a signal two or more sections behind the train. This magnet, when energized, resets the signal to clear. Economy of current is effected by contacts which are opened when the lever n is in position to lock the slide e in the clear position.
