THE BRAZELLE AUTOMATIC HYDRAULIC ENGINE GOVERNOR.
The accompanying illustrations. Figs. 1 and 2, show the Brazelle automatic engine governor, designed to maintain uniform speed of engine with all changes in loads.
The governing is effected by a force pump, A, Fig. 2, pumping oil against a piston B, through an opening C; this opening may be increased or diminished, to change the speed of the engine, by turning the hand-wheel D. The piston rises and falls by the action of the pump, thus regulating the supply of steam to the cylinder. It is claimed that the governor will admit fully 90 per cent. of the boiler pressure to the cylinder when necessary, and that, by turning the hand wheel D, the speed of the engine can be regulated from 20 to 300 revolutions and over. For incandescent lighting it commends itself, as its perfect control of the engine insures extreme steadiness of the light and thus adds to the life of the lamps.
The Brazelle governor is manufactured by the Mid-Continent Manufacturing Co., of St. Louis.
