IPC: G01M15/04
Filed: 1930-04-14
Abstract: 345,124. Engine stop-gear. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Platzer, G. E. ; 1096, Dean Street, Schenectady, New York, U.S.A.) April 14, 1930, No. 11797. Convention date, April 13, 1929. [Class 122 (iv).] A dynamo-electric machine for use with an internal-combustion engine is protected against excess speed by an arrangement in which a tachometer generator driven by the machine is connected with an electroresponsive device for de-energizing the contactor, which connects the machine to the supply, and for opening the ignition circuit of the engine on the attainment of a given speed. To start the engine 10, a push-button 36 is depressed to energize the closing-coil 38 of a contactor 35 over the lines 37, which contactor, in picking up, makes a holding-circuit for itself over contacts 39 and the opening push-button 40. Closure of contacts 42 establishes a battery-ignition circuit for the engine 10, and opening of contacts 43 removes an earth connection from a magneto-ignition circuit. The engine 10 may be started by a starter or by running a dynamometer 12 coupled thereto as a motor from the mains 13. With the engine running and the dynamometer operating as a generator, the field rheostat 16 is adjusted and a push-button 20 closed to energize the closing coil of a line contactor 19 over the contacts 41. The armature circuit of the dynamometer is thus established over contacts 22 whereby, in testing the engine, the energy is returned to the mains 13. The dynamometer also drives a tachometer generator 24, which develops a voltage proportional to its speed and energizes a tachometer 27 and a control relay 28 the operating valve of which may be adjusted by a screw 31 controlling an air-gap in its magnetic circuit. Should a failure occur in the dynamometer windings and cause excessive speed of the engine, the relay 28 attracts its armature 50 and shortcircuits the winding 38, thereby cutting out the dynamometer armature winding and breaking the ignition circuits of the engine.
