IMPROVEMENT IN STEAM-ENGINE GOVBRNORS.
@the ,dgehule referat in in tiges efters rteut mrt making und nf tte time,
T() ALL WHOM IT MAY CONCERN:
Be it known that I, JOHN WOOD, of Brooklyn, in the county of Kings, and State of New York, have invented and made a certain new and useful Improvement in Hydraulic Regulators for Engines; andI do hereby declare `thel following to be a full, clear, and' exact description of the said invention, reference being had to the annexed drawing making part of this specification, wherein I have represented a vertical section Vot" the said regulator illustrative of its mode of operation.
In governors for engines difficulty arises in regulating the relative action of the governor and the throttlevalve or cut-off so that the said valve shall not be moved until a certain speed 4is attained. `The nature of my said invention consists in a. regulating apparatus combined with a pump that supplies liquid constantly to said regulatingapparatus in such a manner that the throttle-valve or cut-nii` is not acted upon until a certain speed is attained, .and the extent of speed can be regulated by thc opening for the escape of liquid from the apparatus.
In the drawingfa represents a pump with inlet valves b b Vand outlet valves c c; the piston d of said pump being worked by any suitable connection to the engine to be regulated. The pump a may be placed above the vessel e containing liquid, or it may be immersed in said liquid, and any desired character of' liquid maybe employed, but I prefer oil or petroleum. `The liquid passes from the' pipe f (provided withan air vessel, 9,) into the regulating cylinder 7L, in which is a piston, 1', and lrod, k, from which a lever, Z, or other connection, A
extends to the throttle-valve m or cut-off. The piston i'is kept down by a spring, ln.` 0 is an outlet for the liquid, regulated by th'cock y, the amount of the opening being such that the engine will attain its maximum velocity before' the liquid will be pumped into the cylinder L suilicient to accumulate and raise the piston z'. Whenthis accumulation takes place the valve m is instantly acted upon, and the piston z' can move sufficiently to close, or nearly so, the throttle or cut-eti. When the accumulation of pressure-and liquid in the cylinder l1, is suiiicient to raise the piston z' considerably, I make use of the motion'of the piston-rod to open a second escape-valve, g, through the agency of the yoke and hooked arm s acting below the handle of said cock to turn the same more lor less according to the height the piston z' rises, and this will prevent injury to the apparatus by a sudden increased speed of the engine. If desired the same object can be attained by thc yoke t'actng upon Vthe lever arm u of a rod that extends to a valve, v, in the pump inlet .pipe w to open the same and allow air to enter the pump, said valve being formed of a perforated disk turning over a hole in the said pipe, or in `any other form. Ansafety-valve is provided at x to take oii surplus liquid fronr the regulator-cylinder ,in case of the cocks being improperly adjusted.
What I claim, and desire to secure by Letters Patent, is
The piston z', spring n, and connections it Z'to the throttle-valve, in combination with the pump a and valve q, operated by a connection, s, tp the piston z', as and foi-the purposes speciedl v Inwitness whereof I have hereunto set my signature this twenty-fifth day of September, A. D. 1866.
JOHN WOOD.
