Abstract

3918. Hintz, K., and Schmidt, A. Feb. 17. Mechanically operated from or by vehicle.-A travelling band b carried by the train is perforated according to the signals, points, &c. of a predetermined route, and by means of the perforations renders operative or inoperative the mechanical signal-receiving devices m, n &c., or a device on the train for moving switch points over. The train carries two stop or signal levers 7n, n linked to vertical bars f, g, respectively, which rise, as shown for the bar g, when plungers h pass into perforations. In rising, the bar lifts the stop-lever m, n, so that the track contact p engages the arm n. This merely lifts the bar g sufficiently to free the band b from the plunger h, and the band is then moved by a spring until one or other of the plungers h snaps into the next hole. If the contact p engages the stop-lever that is not raised, it engages the arm m, which is then given a movement sufficient, in addition to releasing the band. to operate the brake-rod u. A lever 1, 2, 3, Fig. 6, may be fixed to the front of a locomotive and be held in one of two alternative positions by the perforated band. If a train approaches points which are wrongly set, the arm 3 engages a pin 7 and, by it, moves the points over. When the points are properly set, the pin 7 acts upon one of the stop-levers m, n and causes the band to move to the next position.
