vsrs-:AMgalante SPECIFICATION forming part of Letters Patent No. 295,681, dated `March 25, 1884.
' Application med December 17, 1833. (No medal.)
fo @ZZ whom it may concern.- Y
Be it known that I, GEORGE F. SEIsER, of Carrollton, in the county of Carroll and State of Kentucky, have invented a new and useful Im` provement in Steam-Engines, of which the following is a full, clear, and exact description. My invention consists of a contrivance for balancing the back-pressure of the exhauststeam on the piston; also, an improved con- 1o trivance for condensing'the steam; and, also,
improvements in the construction of the engine for accomplishing these objects, all as hereinafter fully described.
Reference` is 4to be had to the accompanying drawings, forming part of this specication,
in which similar letters of reference indicate correspondingparts in all the gures. A
Figure lis aplan view of my improved engine and a pump for removing the condensed '2o exhaust. Fig. 2isasectional elevationthrough the cylinder on the line x :l: of Fig. l and in larger size. Fig. 3 is a section of Fig. 1 on the line y y. Fig. 4L is a perspective view of the middle portion of the cylinder containing the steam ports and valve, and Fig. 5 is a perspective view of the valve.
I make a cylinder, a, of longer dimensions than usual in proportion to diameter, and separate it into two piStOnchambers, b c, in the 3o same line by a middle partition, d, and arrange a piston, c, in each chamber, and onthe same rod, y",which extends through the partition CZ, having stuffing-boxes g. The partition d is bored at the level of the lower side` of the cylinder transversely to said cylinder for the conical three-way valve h,havin g steam-` passages i and exhaust-passage j, which partition receives steam through passage k, and distributes it to the steam-chambers b @through 4o the ports Z, and exhausts it therefrom into the passages m, through which the steam escapes after doing its work on one side of the pistons around to the oppositesides, respectively, and thus aids, by balancing the back-pressure of the exhaust in one chamber, the driving of the piston forward by the live steam in the other chamber. After thus utilizing the exhaustpump, to be forced back into the boiler for feeding the same, or into any other receptacle.
For distributing the water tothe chambers b c, at the proper times for condensing the water, I use the same valve, h,which, besides serving -for the steam distribution, is made to extend. through the water-valve case p, located at the side of the cylinder, and having the inletpipe g, connecting it with a cistern for the supply ot' the water for condensing the steam, and
the pipes n, connecting with chambers b c. In this valve-case p said valve h has one waterway, t always open to pipe q, but alternately open to and shut off from the pipes nas the valve shifts, the arrangment being such that it opens to admit the water to the chambers?) c at or about the time when the pistons begin to receive steam from ports Z, and when exhaust-passage j opens to said chambers. This valve has two arms, u and o, attached to its stems and extending in opposite directions, to be connected with the crank-pin w, or an eccentric, by the rod x, for working the valve,-`
said rodbeing connected to one or the other of said arms, according to which way the engine is required to run. The steam is admitted to the valve i through a throttle-valve, y,
in the steam-pipe z.
It will be noticed that the passages Z are sages in and port j into thesuction-pipe o of a` very short, so that there is but little or no waste of steam for filling them; and it will also be noticed that there are always two chambers open to the exhaust or to the vacuum produced bycondensing the exhaust-steam,which is calculated to add materially to the efiiciency of the engine. l
The engine may be worked to advantage by exhausting into the air after balancing on the pistons and without condensing it; but it is preferred to use the condenser.
Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the steam-cylin der a, having chambers b c and passages m, and the pistons e on the same rod, f, of the par.- tition cZ, separating said chambers, and provided with thepassage 7c and ports Z, and the valve h, provided with the passages 11 j, substantiallyV as herein shown and described.
2. The combination, in a vsteam-engine in IOO which the live steam acts on one side of the exhaust the steam from therdriving side of the piston only, of a valve and passage adapted to exhaust the steam from the driving side of the piston to the other side for balancing the pressure of the exhaust-steam thereon, substantially fas described.
3. The combination, in a steam-engine in which the live steam acts on one side of the piston only, of a Valve and passage adapted to exhaust the steam from the driving side of the piston to the other side for balancing the exhaust-steam thereon, and means for condensing the exhauststeam in the balancing-chamber, substantially as described.
4. The combination, in a steam-engine in which the live steam acts on one side of the piston only, of a valve and passage adapted to exhaust the steam from the driving side of the piston to the other side for balancing the pressure of the exhauststeam thereon, means for condensing the exhaust-steam in the balancing-chamber, and avalve adapted for exhausting the Water from said balancing-chamber when the forward movement of the piston begins, or thereabout, substantially as described.
5. The combination, in a steam-engine in which the live steam acts on one side of the piston only, of a valve and passage adapted to piston to the other side for balancing the pressure of the exhaust-steam thereon, means for condensing the exhausasteam in the balancing-chamber, a Valve adapted for exhausting the water from said balancing-chamber when the forward movement of the piston begins, and a pump for receiving and delivering the Water therefrom, substantially as described.
6. The combination, in a steam-engine, of the divided cylinder a b c, piston e in each chamber, distributing-valvevh in the partition between said chambers, passages m, exhausting the steam into the chambers b c behind the pistons, distributing-valve p 7L, supply-pipe q, and condensing-pipes a, substantially as described.
7,. Thev combination, with the cylinder a, having chambers b 0, divided by partition d, of the water-valve case p, arranged at one side of the said cylinder, and the steam-distribut ing valve h,extending into said Water-case and provided with Way t, substantially as herein shown and described.
