curved pipe H, leading from the outer side of; thesaid cock into the said recess i,'communicatestherewith by means of the outwardly opening valve 70. By turning the key of the four way cock, one of the pipes E, can be thrown into direct communication with the pipe F, and the other pipe E, into direct communication with the pipe H, and vice versa; which causes one of the compartments of the water chamber A, to be connected to theengine cylinder B, by means of anlinwardly opening valve, and the other by an outwardly opening valve, as shown in Fig. 4. Thereby enabling air to be drawn from oneof the compartments of the chamber A, and forced into the other, and vice versa. The key of the four way cock is connected to the beam J, which operates the piston s, of the pumping engine, in such a manner thatthe' saidv key will be automati- :cally operated after a certain number of strokes of the said piston; viz: the lever (1,,

which is connected to the key of the said fourway cock, is attached to a sliding plate 6," which has a cam shaped aperture in it :and is moved back and forth at intervals by a pin h, on the ratchet wheel h, as the said [ratchet wheel ismade to revolve bymeans ofia click pin '5', on the reciprocating pawl bar I the said bar being reciprocated back and forth in consequence of its being joint ed to the lever n, which 'is connected to the operating beam J. l

1 The pin Won the ratchet wheel h,-it will be perceived, works in the cam shaped aperature in the plate 6, thereby causing each revolution of said wheel to move the plate e, once back and forth. Consequently, it will be perceived that by varying the size of the said ratchet wheel, or the number of teeth upon it, the movements of the key of the four way cock may bear any proportion to the strokes of the engine piston that may be desired. The said sliding plate 6, is sustained by the guiding plates f. i

The lower end of the cylinder B, of the pumping engine, is formed with an open mouthed tapering concentric tube a, rising from its upper side. in which the piston rod 4", plays. The piston s, has a tapering tubuflar concentric projection Q), rising from its upper surface, which is of such asize and shape as to allow the annular portion of the piston to descend to the annular portion of the lower cylinder head without coming in contact with the tubular projection a, which rises therefrom. The piston rod r, is connected to the top of the elevated central portion 0), of the piston, and inwardly opening valves to, w, cover apertures in the top of 22, through which air is admitted into the cylinder above the piston.

To insure a proper supply of oil above the piston s, I make an opening in the annular portion thereof and cover it by the inwardly opening valve t. As soon as the oil that has been introduced above the piston, has found its way to the bottom of the cylinder, it will be perceived that it will be at once forced up above the cylinder again through the aperture covered by the valve 2?.

The operation of my water elevating apparatus is as follows, viz: At the start, both compartments of the water chamber A, are filled with water. The reciprocating movements of the piston of the engine, will force air through the aperture, covered by the valve is, into the pipe H, which, by means of the four way cock, will be conducted into one of the pipes E, and by that into one of the compartments of the water chamber.

The air will be forced into said chamber until concentrated to such a degree that the water will be forced therefrom through the education pipe D. At about the time that the water is all expelled from said compartment, the movements of the ratchet wheel h,

acting upon the sliding plate 2, will change the position of the key of the four way cock, and thereby bring the full water compartment into connection with the air engine cylinder through the medium of the pipe E, and the curved pipe H, and the emptied water compartment into connection with said cylinder through the medium of the air pipe E, and the short pipe F, which will allow the compressed air in the said empty water chamber to rush into the cylinder of the engine, and supply the engine with the air necessary to force the water out of the other compartment of the water chamber. As soon as a sufficient quantity of air has been discharged from the emptied compartment of the water chamber to reduce its pressure below the degree of pressure of the water on the outer side of its valve g, the said valve will open and allow the said compartment to again fill with water. And thus the operation may be continued automatically as long as may be desired. The very great advantage produced by supplying the air engine with compressed air from the compartment of the water chamber from which the water has just been expelled, for the purpose of being used in expelling the Water from the other compartment of the water chamher, will readily be appreciated by every one familiar with the subject. Water is forced from the water chamber A, through the pipe I), which communicates with both compartments of said chamber by means of the oifset c, and the tubes 6, b, descending from said offset on either side of the partition a, nearly to the bottom of the compartments A, and A, as shown in Fig. 6.

What I claim as my invention and desire to secure by Letters Patent, is-

The transference of the lubricating oil from the bot-tom of the engine cylinder to the upper side of the piston thereof, for the purpose of insuring the proper lubrication of said piston, substantially as herein set forth.

The above specification of my new and useful improvement in air pumps for raising water signed and witnessed this 27th day of December, 1854.
