Title: Improvement in method and apparatus for controlling combustion
IPC: F23D14/60
Filed: 1925-02-25
Abstract: 252,450. White, A. E., (Surface Combustion Co.). Feb. 25, 1925. Electrically-actuated valves.-A valve in the air or gaseous-fuel supply pipe of a furnace is controlled automatically at regular time intervals in accordance with the deflection of the pointer of a galvanometer connected to flue-gas testing-apparatus. An electric motor 60 in the galvanometer casing drives through reduction gear 61 a shaft 62 extending under the outer end of the pointer 54 and carrying right- and left-handed threads 68, 69 with a space 70 between them. Above the pointer is arranged a square shaft 65 driven from the shaft 62 by gearing 63, 64 and carrying slidably a cam member 72 having spaced circumferential ridges 74. The pointer 54 normally lies above the threads 68, 69 as shown in Fig. 7 so that it is free to be deflected by the coil of the galvanometer. Once during each revolution of the shaft 65 the pointer is depressed by the cam member 72, and, if then in deflected position as shown in Fig. 8, engages one of the threads 68. 69, and by the rapid rotation of the shaft 62 is caused to move back to zero position, moving the cam member 72 along the square shaft 65. This movement is transferred by a fork 76, rod 77, and gear segment 79 to a valve 52 in the supply pipe 14. The action is repeated at each revolution of the shaft 65 until the valve has been adjusted sufficiently to render the composition of the flue gases normal so that the pointer is no longer deflected.
