STEAM-ENGINE.
SPECIFICATION forming part of Letters Patent NO. 351,097, dated October 19, 1886. Application filed March 6, 1886. Serial No. 194,257. (No model.)
To all whom it may concern.-
Be it known that I, DESIRE FIDIJLE ALBERT DEoAIx, of the city of Paris, France, have invented new Improvements in Steam-Engines, of which the following is a full, clear, and exact description.
My invention relates to improvements in valves for the distribution of steam and other fluids in steam and other engines; and it consists of the combinations of parts, including their construction, substantially as hereinafter set forth, and pointed out in the claims.
This rotary or rocking plug or cock is employed in combination with, first, a steamjacket surrounding the cylinder and divided into two compartments or chambers by a central partition; second, a steam-cylinder provided at both ends with holes or notches for the admission and exhaust of steam.
In order that my invention may be more clearly understood, I have shown as a specimen in the annexed drawings how it may be put in practice.
In the drawings, Figure 1 shows asectional view of the valve and cylinder through the line 1 2 8 4 of Fig. 2. Fig. 2 shows a vertical sec tion made through the axis of the distributingvalve. Fig. 3 shows a section of the steamcylinder through the line 7 8 and an end view of the same. Fig. 4 shows a cross-section of the distributingvalve made through line 5 6 of Fig. 2.
Like letters of reference correspond to like parts in all these figures.
The cylinder a, steam-jacket b, with partition 0, and the steam-chest 6, may be either cast in one piece or bolted or attached together by any convenient means.
The cylinder a is provided at both ends with holes or notches q, and the uncut parts are pro "ided with screwed rods 0'. These are employed to maintain in position, by means of suitable nuts, the heads 8 and s of the cylinder.
The jacket I) is connected with the steamchest by the tubes or extensions 00 t a o. The tubes a o are induction-pipes for the admission of steam into the jacket and the cylinder,while w t are exhaust-pipes. The tubes or t, and also the tubes u o, are situated in the same plane, but in rectangular positions. The pipes a: t are alternately put in communication with the pipes Z and Z through the hole or way f of the cook or plug. Both the pipes Z and l are put in communication with the condenser of the machine or left open for the exhaust of steam. The pipes u and o are alternately put in communication with the pipes at and at through the channel or way 9 of the valve or plug d. These pipes at and m communicate with the steam-boiler or with the reservoir containing the fluid to be admitted into the cylinder.
The jacket Z) being provided with a partition, 0, and the channels orways f and 9 being placed in rectangular directions, it is easily understood that, as shown in the drawings, while one of the chambers of the jacket communicates with the steam from the steam-boiler through the tube 1;, the channel 9, and the pipe at, Fig. 1, the other chamber of the jacket communicates with the exhaustpipe Z through the channelf of the plug (1, Fig. 4..
If rotary motion is applied to the plug (1, (either by means of an endless chain, as in the drawings, or by a belt and pulley, or a connecting rod and crank, or an eccentric, or any other mechanism,) the position of the channels f and y will be reversed for each quarter of revolution, so that each of the chambers of the jackets and each end of the cylinder will con1- municate alternately with the steam supply and the exhaust pipe. It will be understood that during each quarter of revolution of the plug the steam expands and acts upon one face of the piston, while the other face communicates with the exhaustpipe. The period of admission at full pressure varies according to the dimensions of the induction and exhaust pipes or leads. These pipes or leads having a constant area, I may work the plug by any suitable cam or other mechanism in order to vary the expansion of steam by increasing or decreasing the time during which the induction and exhaust pipes are putin communication with the holes or Ways of the plug (1.
The area of the holes or waysf andg of the plug is larger than the area of the pipes, in order to ascertain a good working of the distributing-valve whatever may be the longitudinal movement imparted to the plug (1 when the nut i must be tightened on account of the plugbecoming loose in the steamchest.
1. The combination, with the cylinder having a partitioned jacket, of a valve provided with ports alternately connecting with ports opening into the said jacket, substantially as 5 and for the purpose set forth.
2. The combination of a rotating or rocking plug or cock, (1, provided with holes or ways f and g, placed at right angles to each other, a jacket, b, with a partition, 0, connected with 10 the valve by tubes or pipes at t u 'v, and a cylinder, a, provided with notches q, connecting the said cylinder with the jacket, the whole constructed and working substantially as and for the purposes set forth.
day of February, 1886.
