OIL-WELL PUMP.

SPECIFICATION forming part of Letters Patent No. 654,706, dated July 31, 1900. Application filed-March 26, 1900. Serial No. 10,131. (No model.)

To all whom. t may concern.- l j n j Beit known that I, HARLEY E. BEAYMEE, a'

citizen of the United States, residing at Prai rie Depot, in the county of Wood and State of' Ohio, have invented new and useful Improvements in Oil-Well Pumps, of which the follow-4 ing is a specification.

My invention relates to a pump` for oil-j wells, and has for its objects to providean,

eicient apparatus of the kind at greatly-reduced iirst cost and that may be economiclly the tubing and solid sucker-rod ordinarily used.

.The objects of my invention are accom-V plished by providing a pump-barrel locatedV 3 is an enlarged viewof a packing-head.

Fig. 4 is a view ofa packing-head employed` as a substitute for the stuffing-box when-a solid sucker-rod is used.

Referring to the drawings, A is the barrel of the pump, which is formed of a section of tubing of a length adapted to the reciprocation of the working valve and is providedL with the usual standing valve 1, secured in the bottom of the barrel. Coupled to the lower end of the barrel A is a tubular anchor 2, constructed of one or more lengths of tubing closed at the lower end and filled with sand or metal, to anchorthe barrel at the proper distance above the bottom of the well.

chor 2 is provided with 'perforations 3 near 5o its top for the admission of oil to the barrel.

To the top of the barrel A is coupled an eX- Fig. 2 is a like view ofthe casing-head barrel. Fig.V

U jtension 4 of tubing of the same size as the i barrel to extend it to the desired length above, .the lower end of which is provided with perforations 5 and theupper end with a reducercap 6, having an orifice adapted to admit the sucker -rod. At intervals throughout the length of the barrel A its extension 4 and its anchor 2 are provided with collars 7, having radial arms 8, provided with vertical crescent-shaped guides 9 at their ends adapted to hold the barrel, its extension, and anchor central within the cavity of the well.

j 10 is the reciprocating valve, which is a modification of the. caged ball-valve in generaluse in oil-wells, which as usually constructed is provided with a downward tubular `extension 11, secured to the lower end of the 3cage, havinga plurality Aof packing-cups 12 `secured therein by the openend piece 13 and forming an entrance-port and packing for the valve. n l to the downward tubular extension 11 valve 10 is also provided with an upper tubular ex-v tension 14, adapted tothreaded engagement with the upper end ofthe valve-cage, forming an exit-port for the valve, and having a shoulder-liange 15 near its upper end, and with a plurality ofpacking-cups 12, inverted, and held in position between flange 15 and the top of the cage when the extension is secured thereto. The upper end of extension `14 is exteriorly threaded and provided with As used in inyinvention, in addition lifted and forced upward through the tubu` lar sucker-rod 17, which thus forms a substi- V tute both for the-tubing and the solid rod ordinarily employed and renders any other tubing unnecessary, thereby greatly red ucin g the cost of construction.' i 'i As means for delivering the oil as pumped through the tubular sucker-rod 17 I provide at the top of the well a barrel B, having a IOO supporting-flange 18 and a centrally-located lateral branch 19 for connecting it with the distributing-pipe systeirgboth integral therewith. Flange 18 is `adapted seat in the top of the casing-head 20, form a closure therelfor, and support the barrel B in a vertical position central thereto, with the lower end of the barrel within the casing"20 and thelat#V v eral branch 19 and the upper en d above the fro casing-head. In this position barrel B is secured to the casing-head 20 by clamps 21, adapted to engage flange 18 and the top iange.-

` of the .casing-head and provided with set-` screws adapted to tighten the flange 18 in its seat. -Y

The upper end of the tubular sucker-rodA 17 is extended centrally through barrel B and is coupled at the top to a solid rod 17', con.- nected to the pump-jack. The upper length of tubing of sucker-rod 17 is divided into two sections coupled together by au elongated sleeve-coupling 22, having central perforations 23, through which the oil may flow from lthe sucker-rod into the barrel B. Sleeve 22 terial, within the sleeve 25 around the rod andinterposed between the plugs, a metallic washer 29,and a plurality of packing-cups 12. Blug 27 is elongated and shouldered to receive the packing-cups 12 and adapted toY ycompress them against the end of the sleeve and engageone end of gland 28 when it is run into the sleeve. By inserting washer 29 within ythe sleeve at the opposite end of the gland 28 .and running down plug 26 there on, the gland 28 may be compressed tightly around the sucker-rod, and thereby frictionally secure the packing-head 24 on the rod at any desired position and will move with it in its reciprocation and pack the barrel. The cups 12 are placed on the plugs 27 in an upright or inverted position, according as required to, retain the oil. As-used in barrel B the cups on the upper head 24 are inverted, whereby the oil iiowin g through the perforav tions of coupling 22 into barrel B is confined-- -between the upper and lower packing-heads 24 and forms a head of oil reciprocating with the heads,which is discharged through branch 1 9 into the distributing-pipe system. v

When it is desiredto lift the pumping apparatus from the well for any purpose, the tubular sucker-rod 17 is drawn upwarduntil the cage of valve 10 is on a level withthe pertionY the oil remaining in the sucker-rod 17 will iiow back into the well, after which the sucker-rod may be further lifted, and when the coupling 16 at the top of valve 10 comes into vContact with the reducer-cap 6 of-extension 4 the barrel A, togetherl with its anchor 2, .will be lifted -with it, the arms and'guidesof the collars 7 serving to keep it centrally within the cavity of the well and preventing it from catching in any inequalities in its wall, as the entire apparatus is Athus lifted to the top of the well. Inlike manner the barrel A and its anchor may be again loweredinto its position in the bottom '0f the well. Byuncoupling the top of the a smallA rod may be lowered through the sucker-rod, which being reciprocated therein will readily dislodge any paraffin .sediment deposited on the wall ofthe tube.AV

:Fig. 4 shows a modified ,form of casing-top barrel by which when attached to a well having stationary tubing a packing-head 24 may be substituted for the ordinary stuffing-box In this modified form'the barrel 30, having a lateral branch 31, an enlarged'orice 32 above the branch, and a reduced l orifice 33 at the lower end corresponding in diameter with the 35 internally threaded to receive a nipple by which it may be connected to thetop of th? tubing of theV well, is substituted Vfor the and pipe ordinarily employed, and upon the solid sucker-rod 34, within the enlarged orice 32, a packing-head 24, with the packingya cups inverted, is secured in the manner hereinbefore described, which, moving with the rod as it reciprocates, packs both the barrel 30 and the rod 34. By this construction the use of a stuug-box and a polished rod is avoided and the construction cheapened.

Y Having thus fully described my invention, what I claim to be new, and desire to secure by Letters Patent, is

1. Inan oil-well pump, the combination of a pump-barrel having a lower and an upper extension, the lower extension being weighted within to adapt it for an anchor for the barrel, and perforated,"and the'upper extension the barrel and provided with a cap having a reduced oriice; spiders secured at intervals to the pump-barrel and its extensions; a standing valve inthe lower end of the pump-barpump-barrel, comprising a centralcage inclosing a valve and upper and lower tubular extensions of the cage, forming exit and entrance ports `of the valve, each providedwith a plurality of packing-cups, the cups ofthe lower extension being faced upward and those of the upper extension being faced downward and adapted to pack the Valved piston thus formed within the barrel-cylinder; a casing in the topof the well; a casing-headsecured forations 5 in the extension 4, in-which posito the top of the casing; a casing-head bartubular sucker-rod 17 from the solid rod 17 and the necessity for a polished rod avoided.

being perforated above its connection with y tubing of the well and having the lower end IIO rel; a reciprocating yvalved. piston'within the A rel secured to and supported by the casinghead, having a lateral branch for connecting Vpump-barrel adapted to couple the lower end of the sucker-rod to the reciprocating valved piston, as and for the purpose described.

2. In an oil-well pump, the combination of a `casing-head top having a barrel provided with a lateral branch, a packing-head movable therein, and comprising a tubular sleeve internally threaded at both ends, externallythreaded plugs adapted to threaded engagement with the ends of the sleeve and provided with orifices to receive a sucker-rod, a compressible cylindrical gland within the sleeve around the rod, interposed between the plugs and adapted to be compressed thereby to frictional] y secure the sleeve to the rod, and packing-cups upon one of the plugs and adapted to be compressed thereby against the sleeve to pack the barrel.

In witness whereof I have hereunto set my hand this 20th day of March, A. D. 1900. ,Y
