Abstract
290,987. Kemmann, G. May 20, 1927, [Convention date]. Electrical systems, automatic; track apparatus actuating signals on and other than on train.-In a signalling system of the kind in which the train carries an electromagnet energized from a source of direct or alternating current for co-action with a magnetic core with windings on the track, there are arranged, in series with the magnet windings, relays which control, respectively, signals or trainstopping apparatus on the train and signals on the track. Fig. 5 shows a train-carried magnet L energized from a generator M and having in series with the windings a relay N which controls signals or brakes. The windings on the track magnet G are in series with the relay Rg which controls the circuit of a block relay (not shown) which controls the circuits of the adjacent signaloperating mechanism and of the relays of the adjacent advance and rear sections in such a way that the train is protected by the track signals S which, when at " clear," close contacts in the circuit including the winding on the track magnet G and the relay Rg. Fig. 9 shows a signalling system with track magnets 13, 14, 15 at the entrance to sections 31, 32, 33 and a train 1<1> approaching section 31, while a second train 1 is in section 33. The signals stand normally at danger and are cleared as a train enters the rear section and de-energizes the relay in series with the track magnet. Thus train 1<1> on passing magnet 13 de-energizes relay 19 and opens circuit to relay 28; the armature 43 of relay 28 closes the circuit to relav 29 over the contact 26 which has been closed by the passage of train 1 past the magnet 15. Armature 40 controls the operating circuit for signal 10 which is put to danger when relay 28 is de-energized. The armature of relay 19 is replaced by the core of magnet 22 when armature 38 is dropped as the train passes magnet 14. Emergency switches 49, 50 may be provided for clearing the signals by manual operation when necessary.
