Be it known that'IF. S. PEASE, of Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Apparatus for Raising Oil and other Liquids from Deep Wells; and I do hereby declaro that the following is a full, clear, andoxact 'description .thereof,.which will enable others skilled in theart to make and use the -same,-reference being had to the accompanyy ing drawings,'forming part of this speeication, in which- I Figure 1represents in ivertical section of my improvement applied to an oil-well that qportiou of r,the ligure which shows the'cylinders'l) andE being drawn on the sectional lineWof'Fig. 2.' Fig. 2 is a .horizontal sectionalview ofthe air-pump S andl cylinders D E Staken .fon the line wfof Fig. 1'. Fig. 3 shows` aorossseetion' of `'the Iwell and wollftube on theline y of Figui. Fig. 4 shows a "cross-'section of the saine on the line z of Fig. l Similar letters ofreference 'indicate like parts. This invention has for its object to raise .oil `and other liquids from deep wells; and it con niets-in the use within a wellvof an alternate plenum and vacuum of air or gas 'produced by an air-pump or equivalent means, the said plenum and vacuum being applied by means of a suitable conducting-pipe'which is passed .downl into the well within or without the. Welltube in connectionwith valves .andchamloers '-for the passage into the well-tube ofthe oil or other liquids to be raised. 4

A' represents an oil-well, and B .the well tube with'its conducting-spent.

y B i's-anv air-pump,connected at. either 4end ofits cylinder with two cylinders, D and E, the former of 'which is designed to be avaomum-chamber and the latter a reservoir for containing air under-.a high state of compression. The air-pump may be surrounded' by a jacket or tank to contain cold water or any refrigerating substance for 4the purpose of cooling the cylinder of. the pump while itis in operation, '.Lhe pump is fitted with an inletvalve, 4,' andpassage 6 at one end nearest the "ainreservoir E and an outlet-valve, 2, and passage 5 near its other end opposite the exhaustcylinder.A The pipes UV, which conneet'thel pump with the cylinders Dlanpd E, are iitted with suitable valves, 1 andl 3as seen in the Y drawings.

A spiral spring, ,iiitted onthe'j spindle between its cap andihetop of the-k stufng-hox, tends to keep the lvalve I always drawn up to its seat. The stopper'lli-'of the exhaust-cylinder!) is Valso perforated to rcceive the spindle of itsvalve I', and that spindle also hasI a spring, J, andk a capyK,

the latter boing instbeneath the opposite arm a .of-the vibrating* lever G. The 'stopper H has/la channel, ,d, whichbeginsiu e," valve-chamber,efformed within the lower part of the stopper E', and ascends nearly to its top, whence it takes alateral direction through thatside of the stopper vwhisr. isf'to-L I ward the exhaust-cylinder,aud is connected.

with the air-pipe'e.

- From thiscon'strnction itjiellows i operatingthe air-pump :t vaan m-.flnolemilesa perfect, .according to th "erhelleney4 of the pum-p, will be produced'iiith "cylinder D, and air will be forced into andjoompressed inthe cylindeil E..v It'. now one-vibratesthe lever i3# toward the right, one of its armsa will .depress the-valve` I and permitI the` escape,v of ail' therefrom into the air-pipe c, which in this .exi

ampleis passed. diametrically through .thel

stopper H, and intersects and is put into communicationwith the perforation j in thatstop. per. When the lever is released, the spring` J yandthe pressure of the air in the cylinder causes the valve to close. lf'the lever G vis next vibrated inthe opposite direction, the valve l' ofthe exhaustcylinder will be opened vand air from the pipe e will rush intoit with a great velocity, more or less great vaccording to the l'reriection. of the vacuum-formed in the cylinder and the pressure of air in the pipe c.

v'l'he air thus admitted into the exhaust-cylinder is to be removed by means 'of the pumpwhich Iwill att-he same time renew the supply of air in the reservoir and keep up. it; high pressure therein. Vithin the well-tube, near its4 lower end, I forma valve-chamber by means of perforated diaphragms h and i, the lower vdiaphragm, h, being fitted 'with a valve, g, here shown to be conical, and kept from displacen entby a metallic guard, 7, and the upper diaphragnni, being fitted with a smaller valve, ln, of the same form and working beneath a metallic guard, l. The valve-opening` in this d'aphragm' is placed at one side of the centerA ried downward withiufthe chamber A' nearlyto the lower valve. The cross-section, Figs and 4, show the relative positions of the airpipe e and valve n in the upper diaphragm, i, and the valveg in the lower diaphragm.

The operation of the apparatus is as :t'ol. y lows z When the pipe e is put in communica-` tion with the cylinder. E, the air compressed therein will rush with violence through the pipe c into the chamber A and force any liquids and air whichA may be present therein into the small tu-be m, and thence through the valve n upward into the well-tube. By exhausting air from the air-pipe ehinto Ithe cylinder l) a partial vacuum is formed in the I chamber A', which will be immediately filled by the oil or other liquid'vpresent in the bottom of the well, which will pour through the valve g until an equilibrium of pressure is obtained between the contents of the well and the contents of the chamber A. Compressed Vair being again let 4into the pipe 'e, part of the contents of the chamber A will be again forced through the valve aand' its place supplied', as before, by means vof the operation of exhausting air 'from the pipe e and chamber A' into the exhaust-cylinder.

By admitting'air at avhigh pressure into the chamber A and exhausting. the same in alternation by means of the vibrating lever G. the

contents oi' the well will be' forced' upward through the well-tube to the surface of the ground. The vibrating lever furnishes means for repeating this action with great rapidity, and l am thus enabled to raise oil and other liquids in large quantities.

The valves g and n inay be ball-valves if that form is preferred. Thel height of the chamber A may be varied to suit the character of the well, a height varying from ten t0 twenty feet heilig adapted for most wells. The

tubem should be ot' about the same diam.

eter as the air-pipe c, or should not greatly exceed that diameter, in order that the column of liquid'therein may be rapidly discharged through the upperva-lve.

lf it is desired to increase the expansion of `the compressed air after it is delhfered into the conducting-pipe e, heat maybe applied to saidpipef :vt-any suitable point between the vreceiver and the mouth of thc well; butin that case the pipev from the exhaust-cylinder should connect with the pipe e beyond'thc point where the heat is applied, or, in other words, there should be a separate pipe from each ot' the cylinders D and E to connect them with the pipe e.

"Whenthe oil in the well is very deep, its pressure may be found sucient to supply the chamber A by only relieving the lower valve of the pressure of the compressed air without the use of an exhausted receiver or of an airpump to exhaust the irpipe, in which case the said air-pipe need only be relieved by means rof a cock, which shall discharge air therefrom into the common atmosphere after each admission of compressed air into the airf pipe e. But where the flow of oil is sluggish,

an exhausting apparatus or an exhausted re- 'ceiver will be found "of great importance.' The air-pump, which may be of any suitable construction for a double-acting pump, is to be kept in continual' operation so as to keep a plenum in one cylinder and form a vacuum in the other during thc time the lever Gis vibrated.

The operation of the pump and cylinders D 'and E, above described, is similar in principle to the action of an `ordinary pump if the same were used to force air into the tube e by one motion of the'piston, and withdraws it on the return motion, and when it is desired. to use the same column of air` iu order to' rempty and till the chamber A alternately, asyringcpump may be used, or a pump embracing that construction. By connecting the air pipe and chamber A with an exhausted receiver and a reservoir of compressed air I provide a reserve force, so that when the valve of either is opened, the action of the column of air is instaut-aneously brought to bear at the bottom of the well. y

' Inordinary pumping wells the well-tube is from two to two and three-fourth inches in diameter, .and it contains a long rod, generally made of wood, connected with the. plungerv at the bottom ot the well-tube. The diameter of this rod is usually from one and one-half to one and three-fourths of an inch, and it therefore fills up much of the interior of the tube.v Since it is necessary to raise and lower this piston-rod at each stroke of the pump its great length and weight cause the motions of the pump to be very slow7 ranging from forty to-sixty a minute. In my invention I make use of an airpipe, c, of, say,one-]mlf of an inch 'in diameter, thereby occupying less space inl the well-tube than the pstonrod above mentiOned.

It will be seen that I make uso in my inven- V tion not only ofthe principle of raising uids by means of' alternately supplying and exhausting air to and from a. chamber 1in which is pl-.ieed an inlet-valve, (asin thechamber A,)

but also by means of the small pipe m, whose upper end communicates through the valve n 'with the well tubeabove. und whose lower end is immersed in the liquids conta-ined in the chamber A. I use the principle of hydrostatic pressure, the column of liquid in the tube m being made the medium for transmitting to the column 'of liquid in the well-tube above the vulve n the force brought upon the column in the chamber A.

I do notclcim the use of steam or compressed nir for elevating oilor other liquids.

I claim as 1neyv and desire to secure by Letters Patent-jj l 1. Raising oil or other liquids from Wells and other deep places by intermittent pulsative action or repentedxibrntion of a, confined 'body of air or other huid, substantially as ,herein set forth.

wnrd, the upper valve communicating with the chamber. A by means of a. tube, in, substantiall y as described.

4. The vulves g n of the vnlveehembcr A', operated bymeans of the vibrations of al co1- un'in'ouir, alternately filling the chamber with nir und exhausting the same, for the pur; Osc of raising oil and other liquids from deep Wel ls. substantially :is described.
