JOHN K. TRUE, OF SAN FRANCISCO, CALIFORNIA.
IMPROVEMENT IN STEAM-GOVERNORS.
Specification forming part of Letters Patent No. 182,391, dated September 19, 1876; application .filed June 20, 1876.
To all whom it may concern:
Be it known that I, J OHN KNowLEs TRUE, of San Francisco, county of San Francisco, and State of California, have invented a new and Improved Steam-Governor, of which the following is a specification The invention will first be described in connection with the drawing, and then pointed out in the claim. it
Figure 1 is a sectional elevation of the chest containing the throttle-valve, and the small engine for working it, and a side elevation of the governor; and Fig. 2 is a sectional elevation of the whole, taken in a plane at right angles to that of Fig. 1.
Similar letters of reference indicate corresponding parts.
A is the chest containing the throttle-valve B, admitting steam to the valvechest of the engine to be regulated, steam being admitted to said chest by the pipe C. D is the small engine for working valve B, which is connected to the piston-rod E of the small engine. F is the valve to the latter, the rod of which is coupled to the governor G, so that when the balls of the governor rise by increase of speed valve F will descend, and admit steam in the upper end of engine D, which will close valve B and, when the balls fall, it will admit steam to the lower end, and raise valve B.
The spring H on the rod of valve F balances the weight of the valve. The valve F can be set for high or low speed by the adjustable coupling I. J is the exhaust-pipe for engine D.
I propose, in practice, to have the valve F so constructed that both steam-ports will be a little open when both exhausts are closed, so that the piston will be prevented from making full strokes; and, when the opening of one steam-port is slightly increased by the movement of the valve, the opposite exhaust will be slightly opened, to allow a little movement of the piston.
A buifer-spring will be employed, in practice, in connection with the piston and throttle-valve, to prevent them from stopping too suddenly.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 'I-he throttle-valve B, the rod E, and the engine D, the latter having valve F connected with the governor, in combination with, and located in, the steam-chest, as and for the purpose specified. 7
