Filed: 1922-03-27
Abstract: 180,984. Metropolitan - Vickers Electrical Co., Ltd., (Assignees of Moss, C. M., and B³lhimer, F. M.). June 3, 1921, [Convention date]. Systems depending on the use of two or more machines; switching-systems. - In systems wherein a number of alternative sources of power, e.g. 1, 2, 3, and 4 are provided to ensure the constant energization of a circuit, e.g. 5, means are provided whereby, if one source, say 1, while on supply, becomes inoperative, it is out out and a later one put on load, this later one being automatically replaced by the earlier at such time as that earlier becomes available. If, further, more than one early source becomes ineffective, the next later one is put on, to be again replaced by such one of the prior sources as first becomes effective subsequently. Changeover can also be made manually. As shown, but with the switches 6, 7, 8 and 9 in their right-hand position, and the main switch thrown in, the last source 4 is on supply through contacts 48, 40, 25. If now the source 1 becomes available, current flows through the coil 18 of the relay 13 to close contacts at 19 and 20 and open others at 21 and 22. Contact at 19 closes circuit for the relay 10 to break the circuit of the source 4 at 25, and to close contacts at 24 and 25, the last of these putting in the source 1. Contact at 20 entails the energization of the voltage relay 16 and separation of its contacts 31, 32, but on failure of the source 1, the relay 16 fails to maintain the separation and a short circuit is established for the relay 13, which fails and allows contact to be re-established at 21 and 22 while it is broken at 19 and 20, so that the relay 10 becomes ineffective and the source 1 is cut out, but circuit is now made at 22 for the coil 34 of the relay 14 which acts as the relay 13 to put the source 2 on supply. It will be seen that restoration of the source 1 by energizing the coil 13 and breaking circuit at 22 causes the source 2 to be cut out.
