IMPROVEMENT INA GOVERNOR-VALVES The Schedule referred to in these Letters Patent and making par: ofthe same To whom it may concern:

Beit known that-I, THOMAS WARREN, of Flint, in the county of Genesee, and State of Michigan, have invented a new and useful Improvement in Governor-Valves; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, andv to the letters of reference marked thereon, and being a part of this specification, in which- Figure 1 is a perspective view of my invention, and

Figure 2 is a vertical section of the same.

Like letters indicate like part-s iu each figure.

The object of my invention is to construct a double governor slide-valve, working between vertical seats in a case, and so arranged that the pressure ot' the steam is the same on each ofthe valves, making what is termed a balance-valve, for the more perfect regulation of the speed of the engine to which lit is attached, and which is equally well adapted for regulating the supply ot' water delivered to a water-wheel.

My invention consists in the combination and arrangement of the several parts of said valve, and of the case in which it is contained.

A, fig. l, represents a case, within which and oppo-I site to each other are valve-seats B B', having one or more openings, C C', ,as may be necessary.

These openings lead into side-pipes D D', which terminate in a common outlet steam-pipe, E, under the case.

I F F are ordinary slide-valves, provided with ports G G', corresponding in size and number to the openings C C', and having a vertical travel onthe seats B B', and, to prevent swaying or lateral motion, are provided with guides H.

The valvesli I4" are adjusted in their proper positions and there seemed by the right-and-left screws I,

' tapped into their backs, or by any other suitable device which will permit the' valves to be set out against the seats snilcientlyvto prevent leakage of steam, without creating undue friction between them. At the top of' each valve is a groove, J J', in which is placed a nut, K, to which .is secured the lower end of the 4valve-stein L, the upper end of which is connected to and actuated by any proper governor.

M are plates or covers for closing the chest or case N is the iuletsteam-pipe, which may enter the case A at the top or one side, as maybe convenient.

Amon g the advantages which I claim for this device are the following:

The construction of' this valve is such that its open- I ings have sutlicient capacity to convey into the side, pipes all the steam which may enter the chest through the inlet steam-pipe, and consequently preventing any tendency to wire-drawing the steam iu passing through l the slide-valves F F', provided with ports G G,'adjust' ing right-and-leit screws I, guides H, nut K, and valvestem L, in connection with any proper governor, when each ot' said parts isrconstructed as described, and all arranged to operate as and for the purpose set forth. y
