IMPROVEMENT-IN SLIDE-VALVES.
To all fr vhom it may concern A y Be it known that I, `JAMES SMART, of Stratford, Essex, England, have inventedcertan new and useful Improvements in SlideValves; and I do hereby deelare that the following is a full and exact description thereof', reference being had to the accompanying drawing and to the let-ters of reference marked thereon. The slide-valve is made hollow, the steam passing from one side of the valve through the same, and then through the' portson the cylinder face.
The steam-receiving side of the valve works steam' tight against a corresponding face having an oblong hole, through which the steam enters the valve.
. made 4sure to run steam tight on ,both sides.
l The accompanying drawing represents the valve in some of its applications.
Figure l is atransverse section of a steam-cylinder i tted with the improved slide-valve.
Figure '2 is a longitudinal horizontal section of the same ;g and Figure, a sideelevation ofthe same.
The principle will be clearly understood by refer- `lfhe steam enters from the steam-pipe at A, passes through the spaces B and B, and the openings G and C to the top or bottom part D' D on the face of lthe o cylinder, which is made of any ordinary construction,
the valve being adapted to the same.
rl'he opposite, in this case the lower, side of the valve has false ports of about the same area as theports on the other side of the valve, as shown in the dotted lines in figs. 1 and 3. This lower side of the valve works against a hollow V-shaped facing-piece, E, shown in outside view in g. 4. It may be adjusted or pressed' against the valve by means of screws or springs.
The condensed water passes into' the interior of the adjustable face, thus relieving the valve from'water, and consequent pressure. It is drawn off from there' by cocks or Avalves in the ordinary way. I
This valve being a. perfect equilibrium valve, as practice has shown, and no steam passing from the Vinterior to the back of it, there is no need for the ordinary slide-jacket and cover, alight casing being Sudicientto keep the heat in. l l o Stuffing-boxes and glands are also dispensed with, as shown, and there is no .loss of .steam outside the valve.
The slide-valve is also easily removed when required.
The steam likewise takes the shortest and most direct rout to the cylinder.
. Figure 5 is a section of a'valve cast in steclor gun4 metal, in one, with' its spindle. Y v
Figures 6 and 7 show the valve applied to inside cylinders, locomotives, or other steam-engineshaving one common steamchest for two cylinders.
The adjustable facing in fig. 6 is the former shown in two pieces, and in Iig. 7 in one.
In all cases it is advisable that the facing should be keptin position by projecting lugs F F fitting into corresponding holes or recesses.
What I claim as my invention,4 and desireto sc-l cure byLetteI-s Patent, is-
1. The construction of a slide-valve, having ports or openings on two opposite sides, through which the steam is admitted to the interior of the valve, or through -the ports on one side only, the said valve being formed with a chamfer on one or both such sides, substantially as described and illustrated by the accompanyin g drawn g.
2. The construction and arrangement of the hollow steam-chamber, against which the slide-valve works.
3. The arrangement of a hollow facing, against which the slide-valve works, for the purpose of adjust- Lnent and draining and 4. The combinationof the slide-valve, steam-chamber, and hollow adjustable facing, substantially as'described and illustrated. y
