This invention appertains to well head equipment generally, and has for its main object to provide for a combined tubing head, tubing anger and sy'phon device, which co- 8 operate in a manner to enable an operator to readily and easily control the flow of fluid (water, gas and/or oil) from a well, especiall a well flowing in roduction, as well as to e ect the drawing 0 of water accumulations at the bottom of the well whenever necessa Another object of the invention is to provide; for an equipment of the class set forth which will include a master valve capable of being operated to close ed the flow of gas and/or oil while the tubing is in the well casing, and whereby all gas and/or oil will be confined in the well casing and tubing below the master valve, mahng it possible to change any fitti or valve on the well without removing the tubing or syphon valve or dropping the same for the purpose. The said fittings and valves thereof are located above the master valve and are much worn and deteriorated, so as to be ineffective, by the sand and grit ordinarily carried by the oil and caused thereby to impingewith much force on the metal parts by which the oil is conducted.

A further object of the invention is to provide an equipment as hereinbefore characterized, wherebythe oil flow tubing or syphon pipe may be readily and easily parted in place in order to ermit of the closing of the master valve as a oresaid.

A still further object of the invention is to provide a novel form of hanger for eifectively suspending the tubing or syphon pipe downwardly of a well casing, but which readily allows for the gas and /or oil to pass upwardly of the casing about the oil flow tube when the required. a

With the foregoing and other equally important objects and advantages in view, the invention resides in the certain new and useful combination, construction and arrangement of parts as will be hereinafter more fully described, set forth in the appended claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a vertical section through the upper end of a well casing and a preferred embodiment of the parts of the invention in assembly and positioned thereon, a portion of the master gate valve being shown in elevation; and

Figure 2 is a horizontal section taken oh the line 22 of Figure 1.

Referring to the drawings, the embodiment of the invention, as shown therein by way of example, is constituted in a tubular member 10, which is coupled at its lower end to the upper end of a well casing 11, projecting above the round surface, by means of a nipple or the 11 e 12, and which has an annular seat 13 formed inwardly of the upper end thereof to support thereon a hanger 14 for a syphon or oil flow tubing or permanent or stationary well flow pipe 15 extending downwardly of the casing 10 for the removal of fluid accumulations from the bottom of a well. Ordinarily this tubing is permanent or stationary while the well is producing by its natural flow. It of course would be removed for any necessary repairs, and

equipped as a pump barrel in case the well is I to be operated by pumping.

This anger 14: is preferably in the form of a hollow cglindrical body and of a diameter to snugly t inwardly ofthe upper open end of the tubular member 10 for supported engagement on the seat 13, and has a concentrically disposed tubular core 16 within the same and supported from the inner wall thereof by radial web's 17 (Figure 2) the latter being equi-distantly spaced apart to provide passageways 18 therebetween, whereby gas and/or oil may pass from the casing upwardly therethrough about the core 16.. The

well flow pipe 15 is supported from the lower syph'onmg act on of the tublng or pipe is not end of the core 16 by having its u per lend screw threaded into engagement t erewith. The upper end of the core 16 is projected for a slight distance above the hanger body 14 and 1s flared to form a substantially conical seat 19, the latter to be engaged by the lower Y substantially conical end of a verticall .mov-

able extens1on'20 of the syphon tubmg 15,

The extension 20 may seat on the well flow pipe through the medium of the hanger so as to have communication with the well flow 1 e. p upported on the upper end of the tubular body 10, as by having screw threaded en gagement with the outer side thereof, 1s a valve casing 21 in which a horizontal gate or master valve 22 is mounted. The path of movement of the gate valve 22 is in a lane immediately above the upper end of the ared 7 lower ends opening through the casing, while the partition 24 is horizontally slotted for the passage of the gate valve22 therethrough.

Secured in the upper open end of the valve casing 21 is a tubing head 27, which has laterally arranged outlets 28 and 29 opening outwardly at the lower chambered end thereof for conveying fluid from the well casing. The upper solid end portion of the head 37 has a vertical bore formed centrall of the same, through which the syphon tu ing extension 20 depends. Surrounding the upper end of the bore in the head 27 is an annular seat or gland for the reception of a packing 30 which is compressed about the syphon tube extension 20 by means of a gland element 31, the latter being secured in a set position by means of stud bolts or the like 32, thereby forming a sealing bearin for the flow pipe extension 20 and closing t e top of the chamber in the head 27.

An annular flan e 33 is formed about the upper end of the ead 27 to seat thereon a yoke 34, in the upper end of which'the hub portion 35 of a hand wheel 36 is journaled. The hub 35 is provided with a centrally disposed vertical bore which is screw threaded to receive therethrough a complementally scr'ew threaded portion 37 of the syphon tube extension 20, the latter having a mppled extension 38 at its extreme upper end for the attachment thereto of a valve controlled conduit (not shown) to convey"the fluid to be I withdrawn from the well bottom upwardly through the syphon tubing 15 and the extension 20 thereo to a point or points of discharge. The upper, mfppled end 38 of the extension 20 mil pre erably' be exteriorly screw threaded to first receive thereon a gate valve not shown) whereb the syphon tubing wi be closed except uring the normal operation of the well, and also opened when.- ever it is necessary or desirable to relieve the well of water accumulations therein.

In thego eration of'the equipment as thus constructe 1 and arran ed, theflow' of gas and/or oil may be lea ily controlled from the master ate valve 22, and, in the normal operation 0 the well, the gate valve 22 W111 be opened and the gate valve (not shown) at the up er end of the syphon tubing extension 20 is a so open, with the lower end of the latter engaged in the seat 19 at the upper end of the hanger 14. In this condition, gas and/or oil may readily flow upwardly of the casing 11, through the tubular member 10, the passages 18 of the hanger 14, and into the chamber 25 of the valve casing 21, and from thence it will passthrough the lower tubular ortion of the tubing head 27 and outward y of the outlets 28 and 29. In the event that it is desired to close the gate valve 22, as for the purpose of repairing or renewing valves or fittings above the same, the hand wheel 36 will be rotated in a direction to part the ipe and lift the s phon tube extension 20 ii'om 011' the seat 19 o the hanger 14, when the hand wheel 23 will be rotated in a direction to move the gate valve '22 to closed position. "-With the gate valve 22 in open position, and the lower end of the syphon tube extension 20 supported in the seat 19 of the hanger 14, the well is producing oil through the p1pe extension 20. If it becomes desirable or necessary to draw ofl water accumulations from the bottom of the well, the gatevalve (not shown), at the upper end of the syphon tube extension 20 is opened.

Without, further description, it is thought that the features and advantages of the invention will be readily ap arent to those skilled in the art, and it will 0 course be understood that changes in the form, proportion and minor details of construction may be resorted to,.without departing from thespirit of the invention or its scope as claimed.
