STEAM-ACTUATED VALVE.
SPECIFICATEON forming part of Letters Patent No. 313,684, dated March 1,0, 1885.
Application filed March 17, 1884. (No model.)
T0 all 'whom it may concern:
Be it known that I, WALTER S. PHELPs, of Wortendyke, in the county of Bergen and State of New Jersey, have invented new and Improved Steam-Actuated Valves for Steam- Cylinders, ofwhich the following isafull,clear, and exact description. t
The object of'my invention is to provide new and improved steam-actuated valves for the steam-cylinders of steamengines, steampumps, &c.
The invention consists in the combination, with a steam cylinder and piston, of a steamchest containing a series of pistons which are operated by the live steam in the cylinder at the end of each stroke, which live steam, after being admitted into the chest, works under expansion and shifts the pistons, all as will be fully described and set forth hereinafter.
Reference is to be had -to the accompanying drawings, forming partv of this specification,
in which similar letters of reference indicate corresponding parts in all the figures.
Figure lisa side View of a steam-pump provided with my improved valve. Fig. 2 is a cross-sectional elevation of the same on the line x afm ac, Fig. 3. Fig. 3 is a longitudinal sectional elevation of the steam-cylinder and Fig. 4 is a cross-sectional elevation on the line y y, Fig. 3. Figs. 5, l6, and 7 are sectional diagrams showing the different relative positions of the piston and the slidevalve.
A is the steam-piston,working in a cylinder, B,'and secured to a piston-rod, A', which is connected with a pump-piston or with a crank. Gis the steam-supply pipe. Dis the exhaustpipe; and E represents a steam-chest held detachably by screws or bolts on the top of the cylinder, lwhich chest E contains the entire valve mechanism. Both ends ofchest E are constructed alike, and it can easily be reversed, so that either end will project toward the pump;` or it can be placed transversely on the cylinder, as the ports, &c.,which will be described hereinafter, 'and which have their ends in the bottom ofthe chest E and in the top of the cylinder Bare arranged in segmental lines, so that it' the chest E is revolved on its vertical axis and on the vertical central axis of the cylinder the ports of the cylinder and of the chest E will always coincide. The
cylinder B is provided with two channels, b
and b', which lead from the extreme ends ot' the cylinder to the flat portion of the upper' outer surface of the cylinder, the upper ends of the channels b and b being brought quite close together, and between them the channel d is arranged, which projects upward from Vthe exhaust-pipe D to the said ilat portion of the upper surface of the cylinder.
A short distance from each end of the cyl-V inder,which distance is a tritle greater than the thickness of the piston, channels c and c lead to the flat upper surface of the-cylinder. The above-described channels are arranged in the following manner on the said flat surface: In the middle is a circular channel, d. At the sides of the same and concentric with it are arranged the upper ends of the channels b and b', and concentric with and outside of the channels b and b are the channels c and c.
The steam-inlet pipe C, which is screwed into the top of the chest E, is provided with a series of apertures, C', through which the steam can pass into a cup or bell` C2, held on the upper surface of the chest E. The live steam can pass through two or morey apertures, G2, in the top of the chest into the interior of the same. Vithin the chest a cylinder, F, is held, and in the same three cylinders, G, G', and
G2, are held, the cylinder G2 being located in the middle of the cylinder F and the cylinders G and G at the ends of the same. The cylinder G2 is provided with exterior ribs, which t closely against the inner surface of the cylinder F, so that a series of steam-spaces will' be formed between the outer surface of the cylinder G2 and the inner surface of the cylinwith or fitting against the upper ends of the IOO channels b and b in the cylinder B, as shown in Fig. 3.
In the bottom of the cylinder G2 an aperture, g", is formed, which coincides with the upper end of a channel, h2, extending down to the bottom of the chest, the lower end of the channel h" coinciding with the upperend of the channel d in the cylinder B.
In the bottom of the steam-chest channels j and j are formed at the opposite ends, which channels lead from the ends of the chest E to the exhaust-channel h2 in the bottom of the chest.
In the outer ends of the cylinders G and G slots i and i are formed, through which the exhaust-steam can pass from the outer ends of the cylinders G and G to the steam-chambers between the outer surfaces of the said cylinders and the inner end surface of the steam-chest, and can then pass through the channels j and j.
' Between the outer surfaces of the cylinders G and G and the cylinder F steanrchambers K and K are formed, which are entirely independent of the steamchambers between the cylinders G and G and the cylinder F, or the cylinder G" and the cylinder F. Slotsl and Z establish communication between the interior of the cylinders G and G and the steam-chambers K and K. Channels m and m extend from the bottom parts ofthe stean1-chambers K and K to the bottom of the steam-chest, the lower ends ofthe channels m and m coinciding with the upper ends ot' the channels c and c in the cylinder. A channel, n, leads from the cup or bell C2 to the steam-chamber K', and is provided with a cock, L, for closing it.
In the cylinder G'l a piston, H2, is mounted to slide, which piston is provided, between the ends,with an annular groove or recess, J, at each side of which recess packing-rings are arranged,to cause the piston to fit close within the cylinder GZ. The said piston H2 is mount: ed rigidly on a piston-rod, M, and each side of the central piston, H", pistons N and N are rigidly mounted on the said piston-rod, the said pistons Nv and N being contained within the cylinders G and G', and are provided with suitable packing-rings.
On the outer ends of the piston-rod M nuts O and O are screwed and held rigidly, and between the said nuts and the pistons N and N sliding pistons P and P are loosely mounted on the piston-rod M, the said pistons being provided with a series of apertures, o and o, parallel with thelongitudinal axis of the piston. The pistons N and N are provided on the outer ends with short cylindrical projections R and R', in the sides of which annular grooves S and Sare formed. The heads T and T of the steam-chest are provided in theirinner surfaces with recesses t and t', for receiving the nuts O and O" on the ends of the piston-rod M. The two end pistons in the steamthest are provided in their rims with annular grooves w, in which the water of condensation can collect and act as a packing for the pistons.
lf desired, the exhaust-steam in the steamchest can pass offinto the air through apertures u o, in place ofpassing through the channelsjj. l
The operation is as follows: As shown in Fig. 3, the live steam enters through the channel b in the cylinder, to the left ofthe piston, and forces the piston in the direction of thc arrow a', the exhaust-steam in that part ofthe cylinder to the right of the piston being forced out through the channels b h, the groove Jin the piston H2, the slot g2 in the cylinder G,
4 thechannels h d, and exhaust-pipe D. When the piston A arrives at the end of its stroke, as shown in Fig. 5, it almost covers the end of the right-hand channel, b, and has passed the lower end of the channel c', thus permitting the live steam to pass through the channel c', as indicated by the arrows. The live steam passes into the space between the adjoining ends of thepistons N and P, Fig. 3, and as it acts 011 the comparatively small surface of the piston N it moves the said piston and the rod M very gently toward the left. As the piston P is loosely mounted Yon the piston-rod, it does not move with the pistons N N Hi. By moving the piston-rod M to the left, in the manner described. the middle piston, Hf, covers the upper end of the channel h, and also the upper end of the channel h, as shown in Fig. 5, and the piston P keeps the slots or apertures i closed. The steam now acts on the ent-ire end surface of the piston N, as this end surface has been removed from the adjoining surface of the piston P', and thereby the pistonrod M is moved still farther in the direction toward the left, thus causing the central piston, H2, to uncover the upper ends ofthe channels L and h', as shown in Fig. 6. By this time the nut O, on the right-hand end of the piston-rod, has come in contact with the outer surface of the piston P', and has moved the same toward the left sufficiently to cover the slots or apertures Z in the cylinder G, the slots z" still remaining covered. The outer surface of the left-hand piston, N, has struck the inner surface of the piston P, and has also moved the same inthe direction toward the left sufficiently to uncover the slots or apertures l in the cylinder G, and to keep the slots i in the cylinder G covered. The parts are now in the position shown in Fig.v 6. As the steam contained between the right-hand piston, N, andthe corresponding end ofthesteamchest cannot escape, it works under expansion, and moves the piston-rod still farther toward the left. The steam contained between the piston P at t-he left-hand end and the correspondingend of the steam-chest acts as a cushion, to prevent hammering' andjarring ofthe steam piston and rod. By the action of the expansion of the steam the piston-rod M is IOO IIO
moved in the direction shown in Fig. 7, thus permitting the live steam to enter through the channel b and movethe piston in the direc'- tion o'fv the arrow a2, the exhauststeamlpassing off through the channel b and the A'exhaustpipe D or openings o o; but by this movement ofthe piston-rod the piston P has been moved to such'an extentas`to uncover th'eslotsi in.4
