IMPRQVEMENT lN SLIDE-VALVES FOR STEAM-ENGINES.
Specification forming part of Letters Patent No. l 58,06l, dated December 22, 1874; application filed July 23, 1874.
To all whom it may concern:
Be it known that RICHARD Goss, late of -Lanesville, in the county of Harrison and S ate of Indiana, did invent certain new and useful Improvements in Slide Valves for Steam-Engines; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of ref erenoe marked thereon.
The nature of this invention consists in the combination, with a slide-valve for steam-enengines, of an adjustable diaphragm provided with projections on all four sides, which are rounded on their outer ends, and the arms on two sides forming guides for the valve, all as hereinafter more fully set forth.
In order to enable others skilled in the art to which this invention appertains to make'and use the same, 1 will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a plan view of the entire steamchest and slide-valve. Fig. 2 is a longitudinal vertical section of the same. Figs. 3, 4, 5, and 6 are views of detached parts thereof.
A represents the steam-chest for a locomotive or other engine, with the usual steampassages a. a to the ends of the cylinder, and central exhaust-port b. B is the steam-inlet to the steam-chest, said inlet being so constructed as to admit the steam entirely above the valve instead'of against the side or end thereof. 0 is the slidevalve, made square or with perpendicular wall sides, and is provided with a cornice or flange, d, projecting slightly around the top, when the valve is to work on its face, as shown in Fig. 2. In the interior of the valve is a horizontal partition, f, with a narrow slot or opening, 0, extending through and across it from side to side, to allow the escape steam to pass through. Above and over the valve is an adjustable diaphragm or. face-plate, D, suspended from the steam-chest capby collar bolts or rods h, working through stuffing-boxes k on the cap. The upper ends of the rods h are made square to receive a socket-wrench or key for adjusting said rods or bolts. On the lower ends of the rods h are nuts i, which work in mortises or slots made in suitable ribs or projections cast on or attached to the upper side or face of the diaphragm or face-plate D, and by which it is suspended. E represents the valve-rod, connected to the valve 0 by any suitable means. When the valve or valves are made to work on the side or edge, the cornice or flange d is dispensed with, and instead thereof brackets, arms, or studs m are cast on or attached to the side or edge of the valve, and form boxes or bearings for rollers n, to take the weight off of the valve, said rollers running on an adjustable tram or rail way under them. This railway G is made adjustable by means of setscrews 12, passing through the steam-chest, and it is held stationary by other set-screws 8, working in slots at either end, and screwed into the steam-chest.
Being aware that a valve having flanges around the upper surface is not new, I do not wish to be understood as claiming such, except in combination with the adjustable diaphragm D, hereinafter described.
The diaphragm or face-plate D is provided on its sides and ends with arms or projections t t, extending out to the steam-chest, and
rounded on its ends, so as to allow of the diaphragm being raised or lowered at either side or end to bring it parallel to the upper side or face of the valve without destroying its contact with the steam-chest, as these arms or projections are intended'to keep the plate stationary, both side and endwise horizontally,
that it cannot move with the motionof the valve. The diaphragm D is only slightly wider than the valve, and only a little longer than the valve and its throw. The steamchest is made roomy all around, as well as above, whereby plenty of room is obtained for steam to circulate freely between the projections or arms t t on the diaphragm. Guides at m for the valve may be either cast or otherwise fastened on the arms t t, as shown in Fig. 3. Above the partition f in the valve G is formed a recess, as shown in Fig. 2, to admit the escape of the exhaust steam above said partition, through the opening 0, and against the face-plate or diaphragm D, thereby oounteractin g any upward pressure thereof on the valve; and, when using muddy Water, it prevents a great portion of the mud or dirt passin g over with the steam from coming in contact with the under side of the diaphragm, which would cause both it and the valve to cut and wear out much faster than they otherwise would.
By this construction of the valve and attachments a great saving of power is effected by removing the great pressure from off the valve; the engine is handled much more easily, and a greatrsaving in the wear and 'tear' in the valve and valve-motion with eccentric or cam. It also enables much lighter machinery to perform the same work that would otherwise take a great deal heavier machinery to accomplish.
Having thus fully described the invention, what is claimed as new, and desired to be socured by Letters Patent, is-
The combination, with the valve G, of the adjustable diaphragm D, made rectangular in form, and provided With projections t t on all four sides, which are rounded on their outer ends, and with arms on two sides, forming guides x a; for the valve, all substantially as set forth.
In testimony that I claim the foregoing as the invention of the said RICHARD Gross, I have hereunto set my hand this 15th day of June, 1874.
ANNA GOSS.
