Abstract
18,500. Johnson, A. H. Dec. 18, 1908. Signals and points, interlocking; miniature signals. -A mechanical escapement adapted for use as an electric circuit-closer, to be operated by a railway switch - point or point lock, signal, train stop, crossing-gate, or the like, comprises a positivelyoperated member and a second member free to fall when permitted, so opening or closing a circuit, and having, in addition, freedom to move with the positively-operated member when in the escaped position and in that movement to open or close a second electric circuit. For example a bar e, or a bar e<1>, falls into a notch c<2> in a bar c connected to the railway switch points b, b<1>, when the points are in a certain position ; a circuit is thereby closed across contacts j<1>. If the points are forced back, before the bar e is lifted to free them, the bar e moves horizontally about its universal pivot h, carrying with it a bridge-piece k which breaks a second circuit between contacts k<1>, k<2>.
