PUMP.v

Application filed September 6,1924. Serial No. 736,292.

i To all whom t may concern.'

which the following is a specification.

This invention relates to pumps, and contemplates a structure which eliminates the use of a pump rod,`the piston remaining stationary while the barrel of the pump is reciprocated, the invention being extremely simple ,in construction and readily accessible for inspection or repair as the case may be.

The nature and advantages of the invention will be better understood when the following detailed description is read in conv nection with the accompanying drawings, the invention residing in the construction, combination and arrangementA of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a vertical sectional view through the structure forming the subject matter of the present invention.

Figure 2 is a sectional view taken on line 2 2 of Figure 1,

Figure 3 is a sectional view on line 3 3 of Figure 1,

Figure 4 is a sectional view on line 4 4 of Figure 1, l

Figure 5 is a sectional view on line 5 5 of Figure 1.

Referring to the drawingsin detail 10 indicates the well casing provided with a top or cover 11, the latter constituting a base to support a hollow standard made up of a plurality of packing glands and coupled as clearly illustrated in Figure 1. For instance, rising from the cover 11 is a hollow boss 12 to which is secured the adjacent part 13 of a packing gland, the other component part of which is indicated at 14. The part 14 is fitted within the part 13, and interposed between these parts is the packing 15. Suitable fastening elements 16 are used to secure the part 13 to the hollow boss. The part 13 has threaded or otherwise suitably secured thereto a sleeve like member 17, the upper end of which is connected with a coupling 18 having an outlet nipple 19 which constitutes the outlet for the pump. This coupling 18 has screwed or otherwise suitably secured thereto the adjacent part 19 of a packing gland, the other part of which is'indicated at`20. This part 2O of course lits within the part 19, and interposed between saidl parts is the packing 21 as clearlyv shown. The component parts 19 and 20 of this packing gland are secured together by bolts or other suitable fastening elements 22.

A tubing 23 of any suitable-dimension is passed through this hollow standard composed of the elements just described', and entering the well casing 110, and is adapted to be reciprocated when use of the pump is desired. The upper end of this tubing is closed by a headed plug 24, and rising from this plug is a hook like element 25 by means of which the tubing can be reciprocated for the purpose specified. Coupled as at 26 to the lower end of the tubing 23 is a short length of pipe 27 which in turn is secured to a larger coupling sleeve 28, the lower end of which. receives a short length of pipe 29. The upper end of this pipe is normally closed by a check valve 30 which is used in a manner and for a purpose to be presently described. The lower end of the pipe 29 is coupled as at 31 to the upper end of thepump barrel 32, which barrel is provided with a plurality of fluid inlet openings `33.

In this connection it will also be noted that the tubing 23 is provided with a plurality of outlet openings 34. Secured to the lower end of the barrel 33 is a coupling sleeve 35 which is slidably mounted on a short rod 36, the upper end of which has secured thereto a stationary piston 37 wholly positioned within the barrel 32. The lrod 36 may be of any suitable length and has secured to the lower end thereof a weight 37 which is adapted to rest or repose upon the bottom of the well, and thus maintain the piston 37 stationary.

In practice, the piston is held stationary in the manner just stated and when the barrel 32 is moved upwardly from its lowermost position, a suction is createdin the barrel, so that when the openings 33 pass beyond the piston, the fluid is drawn into the barrel as will be readily understood. When the barrel is moved downwardly, the piston forces the water from the barrel through the short pipe 29 into the tubing 23, the check valve 30 closing after each operation to prevent back pressure, or re-' only very simple, but the pump can be conveniently and easily manipulated in the manner and for the purpose specified, and by eliminating the use of a reciprocatory piston rod, the pump can be conveniently removed from the Well for inspection or repair as the case may require.

Vhile it is believed that from the foregoing description, the nature and advantages of the invention Will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to When desired as fall Within the scope of What is claimed.

That I claim' is:

In combination, a Well casing, a cover therefor, a hollow' standard rising from the cover and including a plurality of'packing glands and coupling members suitably secured together, a tubing arranged to reciprocate through said standard and Well casing, and having a plurality of outlet openings positioned at an appropriate point in its length, a discharge nipple projecting from said standard, a pump barrel arranged beneath and in align with saidV tubing and having a plurality of fluid Vinlet openings at an appropriate point in its length, means for coupling the said barrel With the lower end of said tubing, a check valve arranged above said barrel, a stationary piston arranged Within the barrel, a rod depending from said piston, and a Weight carried by the lower end of the rod for holding said piston stationarywhile said bar-- gel is reciprocated for the purpose speci- In testimony whereof I affix my signature.

IVILLIAM EARLE BRGCK.
