Abstract
294,659. Siemens & Halske Akt.-Ges. July 28, 1927, [Convention date]. Order apparatus.-In apparatus for electrically indicating the route of a train the circuit includes contacts controlled by the points in addition to a switch operated by a station official. The Figure shows a line 4 and branch lines 5 - - 8 and indicators 51 - - 56. The operating switches have contacts 11 - - 18 which energize a relay 9 when relay 19 is energized the latter being locked until released by being short-circuited by the train. Further contacts 31 - - 38 on the operating switches control relays 21 - - 28 which control contacts 41 - - 46 in the indicator circuits in which circuits are additional contacts 65, 75, 85 operated by the points. The release of relay 19 releases relay 9 and thus the operating switches which this relay had locked. In a modification (Fig. 2 not shown) the switches may be pre-set by the provision of a storing arrangement of the type employed in liump or gravity shunting yards.
