IMPROVEMENT IN DEEP-WELL PUMPS..

To all whom it may concern:

Be it known that LRErNHoLD BoEKLEN,of the city of Brooklyn, in the county ot'vKings and State of New York, have made certain new and useful Improvements in Petroleum]- Pumps 5 land I do hereby declare that the following is a full, clear, and exact description of the same, reference being had tothe accompanying drawings, in which- Figure l represents a vertical central section oi my improved pump, the piston being shownin the actief its upward stroke. Fig. 2 is a top view ofthe piston of the saine. Fig.

' 3 is a top view of the bottom valve of the saine.v Fig. i is a view similar to Fig. l, but showing the piston in the act oits downward stroke, and exhibiting a modification of' the pistoii\'alve. Fig. 5 represents a vertical section ot'amotlitlcatiou ,of my piston andv piston-valve.

Similar letters of reference indicate corresponding parts in the several figures. f

The nature of this invention consists, first, in providing the valves of lifting-pumps, used in oil-wells', with devices for giving a positive motion to the valves` in correspondence with the' motion of the piston `andindependent of the vacuum or pressure caused-bythe liquids upon which the pump is operatin ,whereby .the nsualdiiculty of the gases c ntained in the well interfering with the proper operation of saidvalves is removed, and .the oil, so t'ar as accessibleby the pump, is readily elevated to the top of the bore of the Well.

It consists, second, in the arrangement and lconnection hereinafter shown, of the pistonrod with the piston, piston-valve, and bottom valve, whereby a positive and corresponding motion of the piston-valve with thepiston and bottom-v'al\'e, .by means of the `piston-rod, is had, and whereby the pressure or vacuum caused by the liquids upon which the pump is operatingis also used to help and make the operation of the valve of said piston and otsaid bottom valve more certain. It consists, third, in providing the bottom .Valve with-al'icsitive motion, in connection with the motion ofthe piston by means of the piston-rod or its equivalents, whereby its action is made more certain and independent of the pressure or vacuum caused by the liquids upon which the pump is operating, while at the same time the advantage arising from said. pressure or vacuum may be used inV combinatiou with the device for giving positive motion,

and whereby considerable powerin operating Athe said valve is saved.

It consists, finally, in the peculiar construction, arrangement, and combination of the devices used, and hereinafter described, for op- A, and made hollow toallow tbeliquidio pass through thesame. Thelowerendof the piston is provided with a valve-seat, F, to which; thev piston-valve E is tted properly, so that by raising the piston-rod D the valveE will close i npontbeseat E. The piston-rod D is guided in a cross-piece, G, formed in the piston, and

also in a stumng-box, H, on the lower end ot` the bottom valve, C, and of proper length to lallow it to be'properly guided inits' full motion.

l I are springs attached to or formed on the top .of the piston, provided with flattops I l projecting "toward the piston rod, and also loosely fitting` the bore ot' the cylinder' in a manner that, with a limited pressure, the said springs Il may be forced apart against thebore of the cylinder. f

J is a boss permanently secured upon the piston-rod D, and is connected at. its lower portion, on opposite sides, by means of links K K, to the corresponding opposite upper parts of the springs I I, and is also provided with grooves L and. L ou its upperlpart in a manner so that the top parts, l I,will project into the groove L, and the joints ot' the links .K K on the boss J are abovethe normal or horizon tal line of the outside joints on the springs I I of the` saidA links K K while the piston-valve is closed; but if the piston-rod D and the boss J are moved downward the top parts, I I', will withdraw from the groove L., andwhen so far that the joints of the links KK are all in line with each other, the springs l Lare expanded, arresting the pistou in the cylinder quite perl marient; and if the piston-rod D is still moved `farther ou till the piston-valve has its full valve closed, and

0 0, 1n a manner to Opening, nien nl@ sain joints or in@ links K K on the boss d should be'as much below their outer joints as they have been' before described to be above the same and the top parts, I. Ii, should then project into the groove L', and thereby `look the piston-valve either in the groove Inwhen in closed position, orinthe groove L when opened.

From the foregoing the operation ot' the piston and its valve maybe-clearly seen. The piston, as shown in Fig. l, is supposed to be in the act of its upvvard'stroke, the piston the springs I I and their top parts, I "if, loch the same in this position until the course of the pistourocl is changed; and as soon as the piston-rod is changed, and as soon as the piston-rod begins to descend, the springslA .I gradually d isengage fromthe groove Land press against the bore ot the cylinder and open the piston-valve until it has its full opening, when the springs I I are fully released from' pressing against the cylinder, and their top parts, I I', engage in the groove L and lock said valve with the piston shown in Fig. 4,. The piston hereafter takes its downward stroke, and as'soon as the course of the piston-rod is changed again to the upward stroke thepiston-valve closes again and is locked in the groove L, as before described and shown in Fig. l.

Instead ofthe conical piston-valve, as shown in Fig. 1a cylindrical piston-valve may be preferred, in order to prevent any impurities tosettle on the said valve and interfere with its operation and, also, instead oi' connecting the piston-valve permanently with the piston rod, it may be loosely connected with it by means of a lever, w, and link y, and it may be arranged to Work inside of the piston With a iiap-valve, c, as shown in Fig. 5; said lastmentioned figure showing a variation in the mode in `which my invention out, as before stated.

"Havin g clearly shown theconstruction and operation of the piston and its valve of my improved pump, I will proceed to describe its bottom valve, C, ofvvhieh M represents its seat. l t is made concave .With tWo valve-openings, N N, as shown in Figs. l and 3.

U 0 are flap-valves Whichare hinged to the outer part oi' the seat M b- 4means of slotted projections P P P P, in a manner to allor:r the" pistonu'od'l); but their outer'i parts, Q Q, are always kept in contact with the seat M. Their inner parte oppositeto the'piston-rod'are provided with friction-rollers lt R, properly shaped to work on the piston-rod D. e

"S S are spriu gs placed in the rear of valves press the said valves O G constantly against 'the piston-rod D, U is an enlargementfon the piston-rod D,its length beinga little less than that of the stroke ofthe piston-rod l).

hefoperationof the bottom valve is as follows, the piston of the pumpsupposed to be said valves 0 to slidetoward and. from the .rising,`tl1e valves 0 0 being'in elevated po 'ating their valve or through the rollers. R R and keeping the valves O O down upon their seat until the upper end oi the enlargement U vhas passed the rollers R R, and the piston changing its course, closing and locking the piston-valve E. Hereby the liquid vabove the piston-valve is raised, While at the'satne time the enlargement U has also taken hold of the rollers R It and opened the bottom valve, and 'the piston causes afresh supply of liquid to rise from the Well above the bottom valve.

Care should be taken before the pump is set in operation that the Well be supplied with air or Water to take the place of the oil as it is pumped oli'. l

From the above it may be clearly perceived that, by having the oil-pumps arranged and l provided with thefdevices herein shown'for operating the valves or' the saine, the same will not be liable to fail to perform their intended function properly, although the gases in the well are acting with a counterpressnre upon The proper levelot the o'il forsuecesst'ul operation should be above the bottom valve, as indicated in the drawings by the line a; but the bottom'valve may be used above the piston,

in which oase the piston'shonld descend .be-

low the level of the oil.

What I claim as my invention, and desire to secure b'y Letters Patent, is-

1.'In the construction'of pumps adapted for elevating petroleum and othertluids from their `Wells,'providin g auxiliary mechanism -for opervalves automatically and with a positive motion, both in the up and down or back and forth strokcs'of the piston, substantially as and for the purpose set fortln 2. In the constructionv of pumps, providing auxiliary mechanism for holding' their valve orvalves either open or as and for the purpose described:

3.The manner, substantially as 'herein defv scribed, or' arresting the piston of' the pump during the time that the position ofthe valve or valves and lthe course of the'piston are he ing changed, for the purpose set-forth.
