UNITED STATES f PATENT OFFICE.
JOHN M. STUKES AND EARNEST K. SMITH, OF SNYDER, TEXAS.
DOUBLE-ACTING PUMP.
SPECIFICATION forming part of Letters Patent No. 658,325, dated September 18, 1900.
To @all whom it may concern,.-
f Be it known that we, JOHN M. STUKEs and EARNEST K. SMITH, citizens of the United States, residing at Snyder, in the county of Scurry and State of Texas, have invented certain new and useful Improvements in Double- Acting Pumps; and we do hereby declare that the following is a full, clea'r, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.
The present invention has relation to that class of deep well double V- acting pumps in which a single cylinder and piston are used; and the object thereof is to improve the pump in the several details of construction,where by the same is rendered .more eective in operation, possessing strength and durability, and the several parts so combined and arranged with relation to each other that economy of space is obtained to adapt the pump to small-bored wells.
The invention therefore consists in a pump of the class above referred to constructed substantially as shown in the drawings and hereinafter described and claimed.
Figure 1 of the drawings is a side elevation of our improved pump, showing it in positionA in a bored well; Fig. 2, a sectional elevation', on an enlarged scale, of the pump -cylinder and its operating parts; Fig. 3, a horizontal section taken on line 3 3 of Fig. 2,looking from the under side; Fig. 4, a horizontal section taken on line -l 4 of Fig. 2, looking from the upper side of the plunger; Fig. 5, a detail perspective View, on an enlarged scale, of the upper section of the plunger; Fig. 6, a similar View of the double frusto-conical valve Fig. 7, a perspective View of the lower section of the plunger which forms the lower seat for the valve; Fig. 8, a perspective view of the clamping-nut; Fig. 9, a perspective viewof the cap for attachment to the upper end of the cylinder; Fig. l0, the upper section of the packing-box valve; Fig. 11, a perspective Viewv Application iiled December 13, 1399. Serial No. 740,211. (No model.)
a sectional view of a deep well to illustrate the application of our improved pump thereto, and B the usual pump-tube,throngh which the water is drawn from the pum p-cylinder O, said pump-tube having the usual lever-handle D for operating it and the usual nozzle E, through which the water is discharged, all of which may be of the usual construction.
The pump-cylinder O has secured to its lower end a screw-cap F,havinga downwardlyextending interior screw-threaded collar o, for attaching thereto a suitable perforated tube G. This screw-cap F has -a valve seat b to receive the valve Hin closing the cylinder against the water entering at its lower end, i the upward movement of the valve being limited by the cage c or otherlike device.
The lower end of the perforatedtube G, which is designed to prevent large bodies entering the pump-cylinder, is closed by a screw-cap d or by any other preferred means. The upper end of the pump-cylinder O is closed by a three-stepped screw-cap I, which cap has radialinlet water-passages e, formed in the sides of a dome J, which is formed integral with the screw-cap and forms the upper 'step thereof. A perforated valve-supporting plate K is held in place upon t-he upper end of the cylinder C by .means of the lower step of the screwcap I, and within the intermediate step is a valve-chamber e'. L is a valve located in the valve-chamber, having a pendent flange l working through the perforated plate K. This valve forms one section of a stuffingbox for the pump-tube B, the lower section of said stuflingbox being shown at M, and between these sections is the usual packingring f. It will be understood thatthe valve L is lowered and raised by the movement of the pump-tube which lowersand raises the stufng box which has frictional contact therewith.
Between the pump-tube B and the interior wall of the dome J is an annular water-space j. to admit the water to the pump-cylinder through the passages @,valve-chamber e', and
perforated supporting-plate K when the valve` with perforated dome, the valve L, the pery forated supporting-plate K, the packing-ring `10, ll, 12, and 13, respectively.
f, and the lower section M of the stuing-box are also shown in detail perspective in Figs. 9,
The pumptube B, which acts as a plunger, has connected to its lower end a plu nger-head which consists of the following parts: A frustoconical perforated valve-section N is provided with a frusto-conical valve-seat n (in which the perforations are located) and an interior screw-threaded neck g, by which the valve-section may be detachabl-y connected to the screw-threaded end of the pump-tube B. This frusto-conical valve-section is formed with a circumferential clamping-flange h, and between this iiange and the flanged clamping-nut O are securely held the two cupshaped packings 7,' t. The flanged end of the valve-section N and also the clamping-nut O are formed with interior screw-threads for connecting thereto an annulus P, having a frusto-conical imperforated valve-seat intermediate of its ends, and between the two valve-seats operates a double frusto-conical valve R, which is closed at its lower end and operated between the valve-seats during the action of the plunger or pump tube. This double truste-conical valve consists of a bottom imperforate disk, a lower part having radial perforations, an imperforate cylindrical central part, (adapted to slide in the u pper cylindrical part of the annulus,) an upper imperforate part, and open top.
The several parts above described which constitute the plunger-head consisting of the frusto-conical perforated valve-Section, the double truste-conical valve, the annulus having the lower valve-seat, and the clampingnut are each shown in detail perspective in Figs. 5, 6, 7, and S of the drawings, the peculiar construction and form of the valve-seats and valve rendering a perfect action of the plunger when the pump is in operation.
In the operation of the pump as the pumptube B is on its upward stroke the valve H at the bottom of the cylinder C is forced oi its seat by the upward pressure of the water, admitting the water into the cylinder below the plunger-head and at the same time forcing the water which is in'the cylinder above the plunger-head through the perforations in the valve-seat n and up through the pumptube B and out through the usual nozzle of the pump. As the pump-tube is on its upward stroke, as above described, the frictional contact of the tube against the Valve L will draw said valve u p against the under side of the screw-cap I, which forms a seat therefor, thus preventing the Water from passing out through the perforations in the dome J at the top of the cylinder C. When this action takes place, the valves H, R, and L will assume the position indicated in Fig. 2 of the drawings. Upon the downward stroke of the pum p-tube B the valve H will be forced down upon its seat by the pressure of water thereon and will raise the valve R in the plungerhead, the upper portion of said valve being brought against the valve-seat n and closing the perforations therein, allowing the water to pass through the perforations of the valve R and directly up through the pump-tube `and out through the nozzle of the pump.
While the pump-tube B is on its downward stroke, the valve L is carried with it by frictional contact therewith a suiicient distance to form a passage for the water in the well, which will pass in to the pump cylinder through the perforations or passages@ of the dome J and through the perforations in the supporting-plate K and keeps the pump-cylinder above the plunger-head full of water for the next upward stroke, when the water will pass into the pump-tube, as Vhereinbefore described, thereby securing a continuous flow of water at either stroke of the pump-tube and plunger-head.

l. A double -acting pump comprising a pump-cylinder, valves located at the lower and upper ends of the cylinder respectively, a reciprocating combined pump and plunger tube, a plunger-head having lower and upper sections providing a valve-chamber formed with lower and upper frusto-conical valveseats and a cylindrical part between the valveseats and a double valve formed with a frusto-conical lower part having lateral perforations and an imperforate lower end, a frusto-conical upper part having an open upper end, and an intermediate cylindrical part of less height than the cylindrical part of the valve-chamber.
