DOUBLE-ACTING PUMP.

Applicativi; mea June 3o, 1915. serial No. 37,185,
To all whom t may concern: Be it known that I, JOHN MASON JONES, a citizen of the United States, and a resident of Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Double Acting Pumps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.
My inventionl relates .tol double acting pumps adapted more particularly for service in drilled wells though it is capable of use 'in any place where it is desired to pump water with the least possible expense of power and the minimum Vof repairs.
The object of my invention is to'provide a pump which is economical in service, inexpensive to build and maintain, reliable in action and which, should occasion require, can be easily and quickly removed from the well for inspection or repairs and then easily restored toworking position.
The novelty of my invention will be here-v inafter more fully set forth and specically pointed out in the claims.
In the accompanying drawing, Figure 1 is a vertical sectional elevation of a pump embodying my invention and showing all of the worln'ng parts'thereof. Fig. 2 is a plan section of the upper4 discharge valve cage and associatedparts, taken on the dotted li-ne A-.A of Fig. 1. Fig. 3.is a sectional plan view taken onl the dotted line B-B of Fig. 1. Fig. 4 is a plan view of the seat of the lower suction valve and also the foot valve to be referred to later. Fig. 5, is a vertical view partly in section, showing the lower end of the pump cylinder, the suction pipe with its foot valve and the well casing.
The same numerals of reference are used to indicate identical parts in all the iigures.
Referring more particularly to Figs'. 1 and 5, 1 represents the usual or any sultable well casing which is driven into the ground and forms the well proper. Inserted` within this casing and suitably supported from the top of the well, is the delivery plpe 2, to the lower end of which is screwed the seat ring 3, and to the latter is suitably screwed the suction pipe 4 which extends downward and well under the level ofthe water in the well. rI he lower end of the suction pipe 4 is provided with a suitable foot valve which consists of the seat 5, disk 6, spring 7 and stud 8, Fig. 5. As shown in Fig. 1, .theseat ring 3 is provided with'an inner tapered seat 9, within which vthe ported plug or casting 10 is accurately fitted, and to the lower end of this plug 10 is screwed the pump cylinder 11, which is preferably composed of brass tubing and is of a length suflicient for Vthe reception of the interior parts of the pump and also the stroke of such parts. The lower end of the, pump cylinderv is closed by the lower suction valve 12 ,which is in all respects, except as tov size, similar to the foot valve before described. 'Aseries ofupper suction ports 13 extend from the space between the pump cylinder 11 and the suction pipe 4, these ports being located in the lower part of the plug 10 as shown clearly in Fig. 1. The upper suction valve14, held in place these latter parts being shown in Patented Dec. 19, 1916.
against its seat covering the ports 13 by spring 15, .which in turn is held in position by ring 16 screwed into the lower end of plug 10, serves to closeA the ports 13, this valve being in the form of airing with a comparatively large center opening as shown.
A second series of ports 17 extend upward through the plug 10 as shown in Fig. 1, and theseports are normally closedzby the lower discharge valve 18 whichvis held in place against its seat by thespring 19 which bears against ,the lower part of the gland 20.
The gland 2O hasa lower flange 21 which aii'ords a stop to limit the upward movement of the valve 18 and the vupper end of this gland is pro-vided with the packing 22 which forms a water-tight joint'against the outside of the hollow piston rod 23. To the lower end of the piston rod 23 is suitably attached the piston 24, which is provided with the cup leathers 24 and followers 24, two of the cup leathers being turned downward and the other two upward in such manner that the-pistonV will suck and deliver w-ater when operated in either direction.
The pistori v24- is attached to the lower end of the pistonrod 23 by means of theJ connector 25 which serves the purpose of connection between these parts and also to compress the followers and cup leathers to hold the same in proper position.
The piston. has a central water passage as upper discharge valve 26, the lower ring or seat 27 of which, in addition to the connection to the piston rod, isscrewed to vthe cage 2 8 which in turn has its upper portion screwed over the lower end of the operating rod 29 in such manner that when this rod vis reciprocated, it, through the connections and parts described, reciprocates the piston-"to pump water from the well.
The operation of the various. parts of the pump is as follows, the parts being shown at or near the end of the up Vstrokeofthe piston, and all of 'the.ports, cavities and l*passages are assumed to be full of water. On theA down stroke of the piston rthe water within the lower part of the cylinder is forced up throughthe hollow piston rod, through the upper discharge valve and into the delivery pipe, while at thesame time a partial vacuum is produced above the piston which.v draws water into the 'upper part of the cylinder throughrthe ports 13,v past-upper suction valveland intothe upper 2part of i the pump cylinder, this water being drawn fromA the space vbetween the cylinder and the suction pipe. 'At the completion of the down stroke of the `piston the upper suction and upper discharge 'valves both close and uponthe beginning `of the up stroke the water which has justf-been drawn. intothe upper part of thecylinder is forced through the discharge ports 17 and past the lower discharge valve and linto the delivery pipe, while at'the same time water is drawn. into the lower :part ofthe vcyl-vinder through the lowersuction valve, which up stroke when completed or nearly so will bring the parts to the positions shownvand thus complete a cycle of operation.
It' is to be observed that there are no ports, .openings or passages or other. means of communication between` the suction and delivery pipes and that there is, consequently, no possibility of leakage between the suction and delivery pipes, and that in consequence of this construction it is possible to maintain the water properlywithin the pump andV that it-will not be necessary to prime a pumpof this construction even when the cylinder isplaceda considerable distance above the level ofthe water inthe well.
ylt is also to -be noted that I employ asingle foot valve of the flat seated type and that this valve is always submerged, thus providing against the lossr of the water in Y the suction pipe.
' all of the discharge valves.
Y It is to be further observed that l can enti-rely remove from the well all of the pump mechanism without in .any way interfering `with the water tightness of the stand pipes above the foot valve and that the removal of these parts includes the cylinder and' all of its parts, including all of the suction and To make ysuch a removal, the operating rod is pulled upward until the piston comes against the lower end of the plug 10 whereupon a further movement of the operating rod lifts the said plug and with it, all of its associated and connected parts as will be readily understood.
Again, it is to be observed that all of the water ports and passages are of liberal size and that there are notortuous passages for the water, .and that .the water in passing through this pump, cando sowith the least possible amount of friction,f.and still further that the construction and arrangement of: the parts :islsuch that Ik can use a cylinder .inwa given v size of well, afar in excess of the sizecylinder whichvit4 has hitherto been possible to use, consequently enabling my pump to deliver .alarger amount of water than pumps `which have been built herebefore.
If' desired,.the lower; edge ofthe seat of the lower suction valve 12 may-.be yprovided with guides 30 eutendingrradially therefrom and bearing against .the 4inside ofthe suction pipe soas to maintain the cylinder in a central position :in the suctiony pipe.
Having thus fully described my invention,I claim;
