Description

charge-valve o is closed, and the valves Y opened, through which latter the water rushes up, and follows piston M into cylinder A. As the piston moves upward, it carries with it the ring-valve Q, and any surplus uncondensedv steam, air, or gases are forced out through the valve V in the head of cylinder A, until the shoulder on ring-valve Q comes into contact with the shoulder on any ring-valve X, which is rigidly secured to rod E. The latter is elevated, bearing ringvalve X against the head of cylinder A, and closing the valve lV, at tl ie same time elevating the rod I, and opening valve H, through which steam is admitted, thus destroying the vacuum in cylinder A, and above piston M.

The moment the vacuum isdestroyed, the water begins to fall by its own gravity, the pistou following, but the steam, exerting its force, whatever little force it has, on the piston, (the openings O ofwhich are closed by ring-valve Q, which descends with the piston,) accelerates the momentum ofthe water, and the more, the deeper the water sinks in the cylinder'. the water begins to fall, the valves Y close, and valve 5 opens, and allows the water to escape through pipe 7. Asthe piston descends', the ring-valve Q strikes against the shoulder R on rod E, and opens the openings O in piston M, allowing the steam from cylinder A to follow the momentum of the water, by passing, through the openings O, into cylinder B, the water in that cylinder, B, acting like a solid piston, which, moving down in cylinder B, would createa vacuum, and .three the steam to follow it, where, mingling with the water, it is rapidly condensed. At the same time, a moment after ring-valve Q has struck shoulder It, the bail S strikes against nut L onrod E, and carries it dowm 'ard ith it, until piston M strikes at the bottom of cylinder A, thereby removing ring-valve X from valve YV, and closing valve H, thus shutting oif the steam from cylinder A. A vacuum is again formed in cylinder A, and the operation continues, as hereinbefore described. l

The condensation ofthe steam, and consequent forming of a vacuum, are very rapid, so rapid, in fact, that I have been enabled to make fifteen strokes a minute,

with a pressure of from ten to fifteen pounds of steam, raising the water a height of twenty-tive feet. The engine would operate were but little steam used, but

The moment.

not as rapidly,for the momentum of th'e water is accelerated by the pressure ofthe steam, t-liough'a greater amount of steam has to be condensed to create the vacuum, which is accomplished by the large surta-cc ot' the coudelming-cylinder, this cylinder heilig kept vin a continuous cool temperature, (the non-conducting packing between it and the upper cylii'ider preventing the latter from heating the formen) and being almost continuously kept iilled with water.

By forcing out the surplus steam, air, or gases, through valve W in the head of the cylinder A, by means of the momentum or concussion of the water, I do away with air-pumps, siphons, and similar' contrivances, and thus simplify the construction and operation of my steam-condensing water-elevating engine.

The rod E is balanced in suoli a manner, by means of the weight on the free end of lever I, that the least amount of power is only required to operate it.

Having thus described my invention,

What I cla'im as new, and desire to secm'e by Letters Patent, is-

l. A 'ater-elevatiug engine, having two cylinders, arranged one upon th'e other, the upper one for receiving the steam, which'aids in expelling the water therefrom, and which, by means of its condensation, causes a vacuum to be created therein, and another, into which the steam from the latter is caused to ilow by the discharge ofthe water from the vfoi-mer, and in which the steam from the upper cylinder is condensed, substantia-ll' as described.

2. The combination of cylinders A and B and float or piston M, with its apeitures or passages (l), substantia-lly` as described.

3. The combination ofthe float or piston M and valve P, substantially as set forth.

4. The combination of the rod E, float M, valves P, Q, and X, substantially as described.

5. The combination and arrangement of valves Q and X on rod E, and valve W in the head of cylinder' A, substantially as set forth.

(i. The arrangement of valve Hin relation and with reference to alves X and lV substantially as set forth.
