OF COLUMBUS, OHIO.
Letters Patent No. 95,225, dated September 28, 1869.
The Schedule referred to in these Lettere Patent and making part of the same.
To all whom it may conce-1in:
Be it known that I, WILLIAM RHAYDEN, of Columbus, iu the county of Franklin, and Stateof Ohio,
have invented a new and improved Direct-Action- Engine; andI do 4hereby :declare that the following is a full, clear, and exact descriptionl thereof, reference being had to the accompanying drawings, making part of this specification, in which y i Figurel, plate 1, is a vertical section, taken longitudinallythrongh the centre of my improved eu-l ne.- Figure 2, plate 1, isa central cross-section through the pistone,
Figure 43, plate 2, is a cross-section, through the `centre of the engine. i
Figure 4, plate 2,.is a top view of the cylinder, with the steam-chest removed.
Simi-lar le tters'ofv referenoefindicate corresponding parts in the several figures..
`The object of this invention is to operate a balanced slide-valve by the alternate action upon its op.
posite sides,of the .pressure of steam, received from a piston, which is chambered and provided with inwardly-opening valves. as will be hereinafter explained. e
.To enable .others skilledjin -the art to understand i my invention, I will describe its construction and operation.
In the accompanying drawings, g. 1
Y represents the cylinder of the engine; R, a piston, working therein.
Q is the steam-chest, and E,'the slide-valve working therein.
. A is the steam-pipe,through which steam passes by way of the branch parts B, intothe steam-cham'- ber K, and acts against the ends of the slide -valve E, so as tobaiancc this valve. The valve E is providediwith stems F F, which pass, steam-tight, through theheads G G, into chambersH' H, and against the reciprocating-plugs D D, which work in these chambers'.
C G aresteam-passages, which are enlargements of steamchamber K, and which communicate with the cylinder Y on opposite ends of the piston R, by way of the ports :t x,- and l is another enlargementpof chamber Ii, which forms a communication between this chamber and the exhaust-pipe I.
O O are ports, passing from the interior of the cylinder Y into thel chambers H H, on the outer sides ofthe small plugs or pistons D D, and
P I) are ports, which pass from the ports :t x into the chambersH H, on the ilmcr sides of the plugs -or pistons I) D.
rlhe ports O pass through connections M M, so as to cross the ports X X,V'w hich connections will not,
however, interfere 4with fthe -free passage of steam through said ports X.
, The piston R is made hollow, andat each end of it a valve, L, is applied, so'as to open inwardly.
This chambered Ypiston has-,slots I "1 cut through it, for the .purpose offorniing communication between the interior of the piston and the spaces H H, through ports O'O, when the piston is at the termini of its strokes.
The tappet I",`at the endrof the' steam-chest, is arranged in line with the plugs or pistons D, and designed for startingwheu the engine is full of condensed steam. r
In fig. 1, the piston R is represented as having completed a strokefrorn the left to the right, with the slot T under the port O, which allows steam that 'was 'taken `into the piston, at the opposite' or lefthand end of the cylinder, to pass into the space H,
andto move the plugs D D and valve E to the position indicated in fig. 1, thereby exhausting theleft end of the cylinder, through ports X I I, and letting the steam into the cylinder, on the right-hand side of the piston.
paring it to be easily moved by thc steam from the interior of the piston at theproper time.
When the piston-completes' its left-handstroke,v
4steam from its chamber will pass up through port O,'v
into chamber H, and move the plugs D D and valve f E to thc right, thereby causing steam to exhaust from the right-hand side of' thc piston, through ports X I I, and admitting steam to the cylinder on the left side ofthe pistou.
Immediately succeeding the opening of' the exhaustports on one side of the engine, the valve L, on the same side of the piston, will b e shut, and thel valve on the opposite side will be, opened, and kept open until the piston makes another stroke In this way, the steam which is used to move the slide-valve is let into the piston.
Having described my invention,
IVhat I claim as new, and desire to secure by 'Letters Patent, is-
1. A balanced slide-valve, E, constructed willi stems 11 11 upon it, and arranged to operate in comL bination with independent plugs or pistons D D, snbstantially as described.
2. The ports O O, for admitting steam on the outer ends of the plugs D, in combination with ports P P, for admitting steam on the opposite sides of these plugs, arranged substantially as described.
3. The' hollow piston It, provided with inwardlyopening valves L L, and with slots T, and adapted to operate a balanced slide-valve, scribed.
4. Steam-spaces C G, as enlargements of the steamchamber K, communicating with the ports X'and I, substantially as described.
substantially as de- Witnesses:
