Title: Improvements in Apparatus or Means for Preventing Collisions on Railways.
Inventor: BEER ATTILIO
Filed: 1899-09-18
Granted: 1900-09-18
Abstract: 18,826. Beer, A. Sept. 18. Signalling and communicating between trains ; s i g - nalling parting of trains; semaphore &c. signals; controlling and locking signals contacts, electric.-Relates to automatic signalling-apparatus for preventing c o l l isions on railways. The semaphore arm g, Fig. 6, is adapted to be raised from the vertical position, representing line blocked,' into the horizontal or 'line clear' position, by means of the electromotor D, and is locked in the latter position by the spring catch k, which is disengaged by the electromagnet l to permit the return of the arm to the vertical position. Near each of these signals are arranged two contact-makers V, Fig. 2, adapted to be closed by one or other of the rollers r, t, mounted on the engine and, preferably, the last vehicle of the train. The roller closes the circuit between the contact u and the spring V, these parts being suitably connected, through the motors D and electromagnets l of certain of the line signals, to positive and negative line-wires, supplied with current from a suitable source of operated by the roller r on the engine, and completes a circuit, which puts the adjacent signal to 'line clear,' and the second signal in advance to 'line blocked.' One of the contacts of the next pair is similarly operated by the roller t on the end carriage &c., to close a circuit, which puts the second signal in the rear of the train to 'line 'clear' and the adjacent signal to ' line blocked.' The remaining contacts of the pairs serve for trains travelling in the opposite direction. Each train is thus protected by two ' line blocked' signals against meeting a train travelling in the opposite direction, and, similarly, against being overtaken by a following train. In case of a train shunting, or if a portion of the train should break away and run backwards, the roller r on the engine (or t on the end carriage) is raised out of action, and a roller t on the engine (or r on the end carriage) is lowered into action, so that the contacts are then operated as they would be by an ordinary train travelling in the direction in which the shunting or break-away takes place. The rollers r, t are mounted on spring plungers I, H, and, when one is raised, it is locked by the spring catch K<1> or K engaging the pin L' or L. When the direction of motion is reversed, the engaged catch is released by one of the pawls M<1> or M on the axle Z, while the roller previously in action is raised into engagement with its hook by the pawl G or G<1> engaging the shoulder H<1> or I'. As an additional precaution, a following train may be signalled to run backwards out or danger, by an additional signal controlled by the contact V &c.
