Abstract

8471. Kessler, N., and Jelich, G. April 11. Gate-opening apparatus.-A vertically swinging barrier is lowered on the approach of a train by an electric motor 6, the train being arranged to complete a circuit through a battery 2 and the motor. A lamp signal 8 and a bell 9 are included in the circuit. An indicating-arm 10 is also arranged to show the direction in which the train is travelling, being actuated by one or other of two electromagnets 14, 15 connected to insulated sections of the line on opposite sides of the crossing. The electro-magnets act on iron plates 13 suspended from arms on the indicator spindle. The gate returns to its raised position when the train has passed.
