STEAM ENGINE VALVE.

No. 60,932. Patented Jan: 1, "1867.

Uivrrn; STATES SAMUEL J. Pnnr, or new YORK, N. Y.

IMPROVEMENT IN STEAM-ENGINE VALVES.

Specification forming part of LettersPatent No. 60,932, dated January 1, 1867.

To all whom it may concern Be it known that I, SAMUEL J. 'PEET, of the city, county, and State of New York, have invented a new and useful improvement in Valves; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a central longitudinal section of my improved valve, taken in the plane of the line a: as, Fig. 2. Fig. 2 is a partial transverse. section taken in the plane of the line 9 y, Fig. 1. Fig. 3 is a detached view of the inside of one of the double valve-plates. Fig. 4 is a similar view of the corresponding valve-plate. Fig. 5 is a detached outside view of the double valve-plates united as employed.

Similar letters of reference indicate like parts.

This invention relates to an improvement in valves for: steam, gas, compressed air, heated air or caloric, water, or other fluids, where a faucet, gate, valve, or cock is used; and consists in a pair of metal disks, fitted in a box or shell to vclose against seats on their opposite sides by being spread apart with a conical wedge, or a straight wedge turning on a swivel screwed between the disks, or which may be operated on by a sliding -wedge or equivalent devices.

A represents the shell of the valve; B, the cap, through which passes a screw, 0, all which parts are constructed, in the ordinary way, of brass or any other suitable metal. The steam or water ways are a a, passing in a line through the shell at right angles to the screw G, with fiat seats 0 c on the, inside of each. In a cavity in the shell A, between the valve-seats c 0, two flat valve plates or disks, 1) b, are placed, so as to. be opposite to the steamways a a when operating to close them,

and resting in the middle on a projection, d,

in the bottom ofthe cavity aforesaid, by which recesses shall be formed on each side, and theedges of the valve-plates shall not strike and become battered when they are forced into place. 'The valve-plates b b are fitted as male and female to each other on dowel-pins e e, as shown in Figs. 8, 4, and 5 5 and in the inner side of the valve-plates are corresponding taper recesses g g, which receive a conical wedge, h, on the end of the screw 0, as seen in Fig. l, which wedge is shouldered on the upper side, so as to catch on a corresponding shoulder in the recesses g g, and lift the valve-plates b I) together from their seats 0 c in front of the steamways a a. The valve-plates b b are made to lie close to each other when the wedge h is raised, and to play back and forth freely between the valveseats 0 a; but when the wedge h presses against the sides of the recesses g g in the valve-plates it spreads them apart, and presses their faces tightly against the seats 0 c in such manner that steam cannot pass by them either through direct or back action.

It will be observed that with this. arrangement of the valve-plates they bear upon the seats and are held rigidly, so that the resistance is positive against the pressure of steam in the ways, and thus close them perfectly while the operating-wedge is forced into the bottom of the recesses in the valve-plates; and also that when the valve-plates are raised in the cavity by the screw the steam or water ways are fully open directly in line with each other for the free passage of steam or water.

It will be observed that this valve is applicable alike to any valve for steam, gas, COlllpressed and heated air, water, or othenfluids, where faucets, valves, gates, cocks, or steamtraps are used.

1 do not limit myself to application, so long as plates and wedges constructed on this principle are employed to open and close valves.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

. The pair of valve-plates b b, in combination with the conical wedge h on the screw 0, or its equivalent, arranged and operating substantially as and for the purpose herein described.

llhe above specification of my invention signed by me this 23d day of November, 1866.
