DEEP-WELL PUMP.

Application filed December 11, 1922. Serial No. 606,033.

To (all 10]?0727: it may concern:

Be it-known that I, HORACE H. TAYLOR, a citizen of the United Sta-tes, residing at San Francisco, in the county of San F raneisco and State of California, have in vented new and useful Improvements in Deepell Pumps, of which the following is'a specification.

The present invention relates to improve:

ments in deep'well pumps and has for its primary object to provide a simply constructed, compact and con'iparatively inex pensive pump which may be cheaply and effectively operated to raise water or other r liquids from deep wells or'other places where a pump is required. the pumping action being provided through the agency of a: fluid pressure from above the well to the pump, which latter is situated below the level of the waterin the well, said force actuating the plungers which operate to raise the water or other liquid.

One of the objects of the invention is to provide a pump which as a compact unit,

n'iay be readily and easily lowered. into a well casing or placed where a pump is to be employed and operated in an extremely effective and reliable manner from the top of the well without the employment of flimsy and complicated control rods, levers orother means of connection between the pump and the top of the well, the operation being automatic and continuous.

The invention further resides in the combination, inter-relation and association of elements of a pump which together provide for simplicity in construction and operation. inexpensiveness and reliability of performance and also to simplify and reduce the cost of deep well pump installation.

The invention possessesother advantages and features some of which, with the foregoing will be set forth at length in the following description where I shall outline in full that form of the invention which I have selected for illustration in the drawings accon'u'ianyiug and forming a part of the pres ent specification. In said drawings I have shown one form of the construction of my invention. but it is to be understood that I do not limit myself to such form since the invention as expressed in the claims may be embodied in a plurality of forms.

Referring to the drawings:

Fig. 1 represents a side elevation of the pump of my invention.

Fig. 2 represents a vertical sectional view of the pump with parts in side elevation and other parts in section.

Fig. 3 represents a fragmentary sideelevation of the pump taken at right angles to the showing in Fig. 1.

Fig. 4 represents a fragmentary side elevation of the pump the lower part being broken and shown in vertical section, certain parts of the mechanism being removed for the sake of clearness of illustration.

Fig. 6 represents a cross sectional view taken on the plane of line 66 of Fig. 2.

Fig. 7 represents a vertical sectional View taken on the plane of line 77 of Fig. 4.

Referring to the embodiment of the invention illustrated in the accompanying drawings, the numerals 1 and 2 designate cylinders of the pump, of which, in this instance there are two. The upper ends of the cylinders are connected with .a header member 3 which, by reducing the fitting 4 at its outer end is screwed into the lower end of the pump tubing 5. The lower ends of the cylinders are connected with the lower header member generally desigated there being relief ports 7 at said lower ends of said cylinders communicating with the interior of the well A. The entire mechanism of the pump is arranged in compact construction, confined between the headers and pump cylinders and is such that the entire unit may be easily lowered into a well or the like from which liquid is to be pumped. The medium for operating the pump will be some form of hydraulic or' fluid pressure and delivered to the pump through a pipe 8 extending along the side of the tubing and pump cylinders to the lower header.

The pipe 8 is connected at its lower end in a. screw threaded fitting 9 carried on the upper side of a valve chamber 10 in which chamber a rotary two-way valve 11. is mountsmall cylinders,

ed. Leading from the chamber 10 are passageways 12 and 13 which communicate re-. spectively with the pump mechanism for the chambers 1 and 2 When the valve 11 is moved into open position, the operating fluid is delivered through the conduit 12 and when the valve is turned intoits other posi-' tion, the supply of fluid to the conduit 12 is out off and the fluid then passes through the conduit 12 In this way the pump mechanism of the cylinders 1 an'd 2 are alternately operated. The conduits 12 and 13 communicate directly with small cylinders 14 and 15 which are provided in the lower header 6.

At points just above the ports 16, whichports communicate the donduits with the there are provided 'in the walls of the small cylinders a plurality of pressure relief ports 17, which are controlled by annular valves 18 and 19 operating within the small cylinders. The annular-valves I 18 and 19 arre fixed by spiders 20 to valve operating rods 21 and 22. These rods are connected at their lower ends by li'nks'23 with the opposite ends of a. rocker arm 24. The rocker arm 24 is secured to a stud shaft 25 which stud shaft is carried by the valve 11 and extends outwardly through one wall of the valve chamber 10. By this arrangement, the pressure relief ports 17 are closed when the fluid operating pressure is being delivered to the cylinders, and when the valve is operated to reverse the flow of pres sure as will he later described, one of said annular relief valves will open through movement of the rods to which it is connected. The upper ends of the small cylin-.

ders 14 and 15 are connected with pressure cylinders 26 and 27 which extend upwardly into the main or pump cylinders 1 and 2, and are open at their upper ends, havin a working fit within the cylinders 1 and 2. 0- operatin with the cylinders 26 and 27 are piston-like plunger-s 28 and 29, depending from which plungers are cylinders 30 which telescope and have a working fit upon the cylinders26 and 27. The lower ends of the cylinders 30 carry a. stuffing box or packing arrangement 31 which provides for the effective sealin and working fit of the cylinders 26 and 27. It will be seen that the fluid operating medium under pressure within the cylinders26 and 27 will cause the plungers 29to travel upwardlywithin the pump cylinders-1 and 2.

. provided in the walls ofthe cylinders 1 and 2 adjacent their upper ends. The'header 4 is provided with a wall 33 extending over the upper ends of the cylinders 1 and2. The

' wall 33is provided' with outlet ports 34 and 35' which permit the water from the cylinders to pass upwardly from the header and into the tubing 5. Controlling the openings 32 are ring or annular valves 36 and 37 which are fastened by spiders 38 to the lower endsof valve stems 39 and 40. The stems extend upwardly, from the annular valves As a means for automatically operating 7 the valve 11, the plungers are provided with depending arms 43 which carry rings 44 that slide upon the rods 21 and 22 andare adapted to abut'stop members 45 carried adjacent the upper ends of the rods 21 and 22. It

will thus be seen that just before one of the plungers reaches the end of its stroke, one of the rings 44 will engage the stop and cause the rod thereby aifected to be lifted whereupon the rocker arm will rock and'the valve will be operated to reverse the flow of operating fluid. Coincident with the movement of the rod, the annularivalve controlling the pressure relief ports at the. lower ends ofone of the small cylinders, will be lifted, for example, as'shown in Fig. 2. A

cushioning spring 46 is provided so as to be engaged by the lower ends of the cylinders 30 on the return stroke of the plunger.

Assuming that the pump as shown in Fig. 2, is installed in a well or other place where it is desired to pump liquid, the pump may be immediately put into operation by' the use of some actuatingfluid such aswater, air or gas, under pressure, which fluid will be conducted tothe working-cylinders of the pump through the pipe 8. It will be noted that the pump may be lowered into the well easily and without requiring preliminary in-- stallationfspace and thatthe .pump is free from employment of rods, chains or other control elements leading to the top of the well, it only being necessary to use the feed pipe 8 leading from a fluid pressure mechanism such as a pump, not shown, and located at the top of the well.

As shown in Fig. 2, the pump and cylinder 2 has completed its pumping operation and shifted the valve so that the operatin fluid from the pipe 8 is delivered throng the conduit 12 to the small cylinder 14. When this operation of the valve has taken place, the relief ports 17 of the cylinder 15 are open, due to the raising of the valve 19 and the operating fluid escapes-through the ports 17 The liquid below the head of the plunger will be discharged as the plunger recedes through the port 7. When the pressure on the plunger is removed, the valves 42 and 37 gravitate or drop into such position that the valve 42 is closed and the ports 32 are opened. The weight of the valve, also the pressure of the water in the column till standing in the Well and in the tube 5, will tend to move the valve and connecting stem therefor, as described. Water then enteis the cylinder 2-through the ports 32 and the weight of the water on the plunger, also the natural tendency of the plunger to drop, will cause said plunger to move quickly into its normal position, The springwill cushion the jar as the plunger drops int-o normal position. Thus the cylinder 2 is thereby auto matically rendered ready for another pumpi ng operation. As the operating fluid under pressure passes from the member 12 to and enters the small cylinder 14. it passes up into the cylinder 26 and causes the plunger 28 to rise pushing more of the water standing in the cylinder above the plunger. Upon the first up movement of the plunger 28, the pressure of the Water on the under side of the valve 41 causes the valve to lift and this raises the valve 36 and closes the ports 32. The valves 36 and 41 remain respectively in closed and open positions throughout the remainder of the stroke of the piston, and the liquid passes through the port 34 and up through the tube 5 tov the top of the well just before the plunger reaches theend of its stroke. The ring 44 encounters the stop 45 and lifts on the rod 21 causing the relief valve 18 to uncover the port 17 and at the same time operating the valve 11 to shut off the supply of operating fluidto the cylinder 1 and turn said supply into'the cylinder 2. The valves 36 and 41. and the plunger 28 return to normal position as previously described in connection with the pumping operation. This operation takes place quickly-and upon each stroke of the plunger a large quantity of liquid will be raised and pumped out through the tube 5. A relief valve is arranged in the lower portion of the valve chamber 10 and opens automatically in response to excessive pressure in the chamber 10 so as to relieve the pump parts from excessive strains and possibility of breakage or derangement. This alve may be constructed in any suitable manner provided that it will open automatically when the pressure reaches a predetermined point.
