PUMP.

To all whom it may concern:

Be it known that I, Jnssn B. Gannon, a citizen of the United States, residing at Salem, in the county oi Columbiaua and State of Ohio, have invented a certain new and useful Improvement in a Pump, of which the following is a full, clear, and exact description, ret'erence being had to the accompanying drawings.

This invention relates to reciprocating pumps of the type adapted to operate upon movement of the piston in both directions.

The objects include the provision of a simple, e'tiicient construction, capable of being cheaply manufactured and durable and etlicient in use. The present invention is particularly concerned with the construction of such pump adapted to be hand-operated, and one of the objects is to provide a self-contained structure in which an air chamber surrounds the piston, the whole forming a compact unit.

More specific objects include the design of the parts so that they may be conveniently assembled and whereby leakage, either of water or air from the compression chamber, is prevented. For example, a stuffing box cap surrounding the piston, and acting in its normal capacity as a seal, has an extension projecting below the normal level of the water to "further act as a water seal against the escape of air, is so arr. nged that when it be removed it permits removal of the piston, cylinder and associated parts from the pump casing.

The means for carrying out my invention will be more fully set forth in the following description which pertains to the accompanying drawings, and the essential features will be summarized in the claims.

In the drawings, Fig. l is a vertical section through a pump constructed according to my invention; Fig. 2 is a side elevation of the pump on a reduced scale; Figs. 3 and 4; are elevations of the upper and lower cages removed from the pump; Figs. 5 to 9, inclusive, are sections taken on the lines 55 to 99 respectively.

My invention is directed, in general, to the provision of a force pump wherein the water raised from a well or receptacle is caused to flow into an air compression rescrvoir formed between the pump casing and the cylinder wall, whereby a steady flow of water maybe obtained. Accordingly, in the indicated at 13 and 14;, are disposed vertically with relation to each other, whereby gravity assists in closing the valves. A iston operating handle 15 is shown as i ulcrumed on a standard 16, which in turn may be carried by the pump casing or by a base 17, as shown in Fig. 1. The details of the construction will now be described.

The casing 10 may be a: hollow casting having inturned flanges or heads and 21. provided with openings to receive the pis ton cylinder 11. The upper interior portion of the reservoir is larger in cross sectional area than the bottom portion, forming an air and water chamber, effecting a steady flow of water through an outlet 22' at or near the lower end of the chamber; A discharge connection 23 is shown attached j to the outlet 22.

The shell or cylinder 11 may be a seamless tube having its ends thereof internally threaded, and having a smooth exterior which closely fits within complementary openings in the upper and lower heads of the casing. The cylinder is secured in position by members 25 and 26 in the nature of flanged collars presenting angular portions whereby they may be conveniently turned to cause a screw threaded portion to engage the internal threads of the cylindrical member 11, while the flanges overhang the adjacent head portions of the casing and serve to position the cylinder, and at the same time clamp upon gaskets 27 and 28.

The upper member 25 is so formed that it may serve as a stufi'ing box for the tubular piston 31, it being provided with pack-. ing compressed by a collar moved inwardly by an internally threaded head or nut, as shown. The lower end of the member 25 is provided with an extension reduced below the diameter of the threads, engaging the cylindrical tube, to allow water to pass through theopenings 29 from the interior of the cylinder to the casing, and at the same time this extension 25 projects below the lower sides of these openings and thus be low the normal water level, forming a water seal.

The lower clamping member 26 is provided with an upper extension forming a ball valve cage, designated 34, while having an inwardly projecting valve seat 35 for the valve ball 13. The intake pipe 36 is threaded into a downward extension of this same member 26. The convenience of this unity of structure in the one member 26 will be apparent, as the construction and machine work, on this part, consist of simple operations; yet it functions as a clamping member for the cylinder; there is a threaded extension for the intake, and a mounting for the inlet valve, which make for convenience and simplicity. This member, it will be seen, being hollow, forms an inlet-passage for the water to pass this valve ball into the lower end of the cylinder. A pin 37 extending across the upper portion of the valve cage may retain the valve ball 13.

The member 26 may be threaded into the cylinder, before the cylinder is inserted within the casing, and then locked against rotation relatively to. the casing by a proje'ction 3.8 carried thereby. This projection may be' placed between lugs 39extending downwardly from the lower portionof the casing, as shown particularly in Fig. 9. In this way, the pump may be assembled by inserting the cylinder from the bottom of the casing and then locking it against the topv thereof by means of a locking member 25. A further purpose for this look indicated at 38 and 39 is, that the pump when once assembled, may be readily threaded onto a conduit 36 without unthreading the member 26 from the interior of the cylinder, v

The means 15 for operating the pump may befimbodied in a handle 15 one end of which is pivoted, as at 40 to a yoke 41, which is adapted to be rigidly attached to the outer end of the piston 12.

The fulcrum for the handle is indicated at 42 as being a pin connection which is supported by the bracket 16. The lever may have a series of openings as at 43 for engaging the fulcrum pin 42 and the bracket may be pivoted, as at 44, for permitting @the piston to be adjusted to the convenience of the, user. I, V p

, The bracket 16 preferably comprises a single strip of metal formed in' such manner that the ends thereof are pivotally supported on the connection 44 while the intermediate portion forms a support which StraddIesthe leVer and carries a fulcrum pin 42. The manner of connecting the ends of the bracket to'the support therefor, is embodied in aset of oppositely disposed lugs 45 on a base 46. The base is shown as havinglan upstanding flange 47 which surrounds the lower part of the casing and serves as a support therefor. A suitable clampim screw. 48 may be used with the in thecas'ingllQ.

piston on the suct-ion stroke. When the up- 7 ward motion of the piston isQstopped, the weight of the water, drawn into the cylinder forces the Valve 13 to the seat 35,.thus

trapping the .water within the cylinder. Then as the the entrappe water pushes the valve 14 upwardly, whereupon the water flows throughthe openingsv in the cage 31 into the space above the valve 14 and between the piston 12 and cylinder 11, passing through the openings 29 and into theca'sing10. Then'when'the downward motion of the piston is stopped, the valve 14 engages the seat 32, thus trapping water between the valve and the top. of the cylinder. On the next suction stroke, the Water above the, valve 14 is lifted, and is caused to pass through the openings 29 and into the casing 10. On the following discharge stroke, then, the water trapped between the valves 13, and 14 passes into the cylinder andabo've the valve 4 as before. It follows then, that on each reciprocation, water is flowing from the cylinder into the airjchamber formed In view of the foregoing description, it will be seen that a, pum constructed in accordancewith my invention embodies few working parts, and employs valves which are so arranged thatfla quick seating action may be obtained. Furthermore, the relation between the cylinder and pump casing is such, that a discharge head under air pressure may be maintained in: the casing to provide a uniform flow. The arrange ment of the ,arts is such that with the air chamber surrounding, the piston a comparatively short pump is provided, while the water passages are'easily made and are very direct. The extension on the stuffing 1m member provides awater seal so that leakage of air from the air chamber is prevented without requiring an air tight fit in this stufiing box. The parts are very accessible, as removal'of the" s'tufiinig box cap allows removal of the operating elements.

Having thus described my invention, I claim v p 1. A pump comprising-in combination, a hollow cylinder having theends thereof internally threaded, a casing surrounding Cpiston is forfid downwardly,
