GEORGE'E. FOSTER, OF PLACERVILLE, CALIFORNIA, ASSIGNOR OF ONE- HALF TO GEORGE W. KIMBLE, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 588,415, dated August 17, 1897.
Application filed February 19, 1897. Serial No- 624,144=. (No model.)
T0 at whom it may concern:
Be it known that I, GEORGE E. Fosrnma citizen of the United States, residing at Placerville, county of El Dorado, State of California,
have invented an Improvement in Governorvalve for governors and for use in pipes through which water is flowing.
It consists in a novel construction of the valve-chamber with a valve adapted to be rotated therein, said chamber having a retaining-bar disposed therein near the outlet end and parallel with the axis of the valve, and in certain details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a longitudinal vertical section of the valve-case. Fig. 2 is a horizontal section. V
The valve-case consists of a chamber A, within which the valve B is revoluble, and extensions 0 O at right angles therewith, with flanges by which they are connected with the line of pipe in which the valve is to be placed.
The valve is in the form of a cylinder having a segment 5 out out of it, as shown, leaving two cylindrical flanges b at opposite ends. The remainder of thebodyof the valve extending between these cylindrical ends is of the same curvature with these flanges.
The valve-case has a step E,formed in the bottom, and the lower end of the valve has a stem F, adapted to fit and turn in this step.
Upon the top of the valve-case is fitted a cap G, provided with a suitable stuffing-box to prevent leakage at this point, and through this stufling-box passes a stem H of the valve, by which the latter may be turned so as to. open or close the passage through the valvecase.
When the valve is closed, it stands with the semicylindrical back portion across the valve, thus allowing a free flow of the water on the side.
I is a vertical bar projecting into the valvechamber, so that the valve as it rotates forms contact with the face of this bar upon the side of the water passage or opening.
The chamber in which the valve rotates is of such form that the water may pass around and behind the valve, and being held by the retaining-bar it makes the .valve a balancevalve. When the valve is closed, this bar serves to retain the pressure of the water on the back of the valve, and the valve is always surrounded with water whether it be opened or closed, thus perfectly balancing it in any position in which it may be placed.
This invention is designed for use substantially in the manner that is well known in this art and will be made to operate with a ball-governor, water-wheel, and water gate or valve, neither of which is shown, as they form no essential part of my present invention. To make my present invention fully understood, however, I will state that the usual attachments of a steam-valve governor, balls, and springs are to be connected with the stem H of my valve. The governor is regulated for the number of revolutions that the water-wheel is to make to give the desired horse-power to run the machinery. When the water is entirely out 01f by the usual water gate or valve between my valve B and the head or inlet of the water-main, this valve stands wide open, and when it is desired to start the machinery the water-gate is opened, and as the water passes through it sets the wheel in motion, and the movement from the wheel operating upon the governor will turn the valve B to a position which will permit only sufficient water to pass through to give the water-wheel the required speed. When this speed has been obtained, it makes no difference how much water may be available through the main-gate. The valve will only permit so much to pass it. If more power is needed by some other machinery being attached, the valve will take a position admitting enough more water to pass to keep the wheel to its proper speed, and in the same manner if some of the load is removed the valx e will close sufficiently to shut off a quantity of water equal to the amount of power taken away. The valve B does not ever completely close the water-passage, but it acts like a steam governor-valve to regulate the How of water by its opening or closing, and it is partially balanced by being nearly surrounded by the water under pressure in the pipe.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A cook or valve extending transversely across a water pipe or way and turnable in its chamber, said valve having a cut-away segment which when standing in line with the water-passage allows the water to flow on the in both its open and closed positions, and is partially balanced.
In witness whereof I have hereunto set my hand.
GEORGE E. FOSTER.
