IMPROVEMENT IN GOVERNORS FOR ENGINES.
Specication formingrpart of Letters latent No. 168.165, dated September 28, 1875; application led August 30, 1875. Y
. To all whom it may concern:
Be it known that I, JAMES W. MATHIESON,
A ot' Brooklyn, in the county of Kings and or lever from the throttle-valve ofthe enginef A weight surrounds this cylinder, and is supported by said cylinder in its normal position.
The piston-rod passes through Said weight, and is provided with a collar, so as to lift the weight during its upward movement.
The fluid in the cylinder acts against the under side of the piston, and is of the same pressure as that inthe air-chamber or discharge-pipe of the pumping-engine; hence, ii' the maximum pressure is exceeded, the piston is moved against the action of the weight, the throttle-valve partially closed, and the speed of the engine lessened. As the pressure upon l the piston diminishes the weight gradually lowers the piston, opens the throttle-valve wider, and admits more steam to the engine, thus regulating the speed according to the pressure of the uid being pumped.
In the drawing, Figure l is a vertical section of the regulator, and Fig. 2 is an elevation of au engine and pump with the regulator applied thereto.
a represents the steam, and b the pumping, engine. c is the steam-pipe, and d the throttlevalve. These parts, being of usual character, do not require further description.
The cylinder of the regulator is supported throttle-valve d by the lever l. A Spiral spring,
m, below the piston-head assists the piston in its upward movement, and acts to prevent a sudden motion in either opening or closing` the throttle-valve. A pipe, n, passes from the cylinder c below the piston to the air-chamber p 01 discharge-pipe of the pump, or to the reservoir, so that the pressure acting to force up the piston, and thereby to close the throttle-valve, is the same, or nearly so, as the pressure in the pump or reservoir. A Weight, r, is provided around the cylinder e, and in a normal` position it is supported upon said cylinder, as shown in Fig. l. The piston-rod t passes through said weight, and a collar, 2, upon said rod serves to lift the weight when the piston is forced up by reason of the; pressure in e increasing beyond a iixed point.
This weight acts against the pressure of air or other iiuid in the cylinder c, and being ot' the proper weight to balance the maximum pressure, the weight will be lifted if that pressure is exceeded, and partially close the throttlevalve of the engine, to lessen the speed thereof, and as the pressure of the fluid in the pump lessens, the valve vwill be opened wider, so as to regulate the speed ofthe engine automatically by the pressure in the pump.
The hollow weight r, resting upon a collar upon the piston-rod t', in combination with the piston h, cylinder e, throttle-valve d, pump b, and steam engine a, for regulating the speed oft-11e engine according to the pressure in the pump, substantially as set forth.
