TUBING AND rackn'veron OIL-WELLS.

To all whom it may concern Be it known that I, ALBERT J. MGNALLEN, a citizen of the United States of America, residing at Gore, in the county of Hocking and State of Ohio, have invented certain new and useful Improvements in Tubing and Packing for Oil-Wells, of which the following is a specification.

The present invention relates to tubing and packing for oil wells, and is designed especially for the purpose of improving the construction of the packing and joints in the well tubing and barrel of the oil pump in order to prevent waste or loss of oil, and make the glands and packing material'tightfitting in their tubes.

The invent on conslsts essentially in certain novel combinations and arrangements of parts for accomplishing the above purpose as will be hereinafter more fully described and claimed, reference being had to the accompanying drawings in which I have depicted one form of the physical em-' bodiment of my invention which has proven highly satisfactory and efficient. I

Figure l is a partial sectional and partial elevation view, showing the upper end of the oil pump tube and oil outlet therefrom and the pump barrel and cable, showing also thesocket at the lower end of cable. Fig. 2 is a sectional view on line A-A of Fig. 1. Fig. 3 is a View similar to Fig. I

2 but showing the jaws of the clamp device opened, to give access to the sectional parts of the gland. Fig. 4 is a plan view of the upper end of the oil well tube showing the sectional gland therein. -Fig. 5 is an enlarged detail sectional View, showing the manner of securing the cable to the socket.

In illustrating the construction and application of my invention I have utilized the usual oil tube 1 forming part of the pumping device and including the T sec tion or coupling 2 with the oil outlet 3 to which the bushing 3 is connected by the threaded coupling sleeve 4.

The bushing as clearly shown is open at the top and formed with a pair of perforated and threaded ears or lugs 5, 5, projecting from its upper edge, while near its lower end, which is of reduced diameter,

an annular shoulder 6 is fashioned upon which shoulder the lower sections 7, 7 of the packing gland are seated. The upper sections 8, 8, of the gland are separated from the lower sections 7 by the packing Specification of Letters Patent.

material 9 of suitable type or character, and each of the four gland sections is formed with hemispherical'grooves for the free movement of the pump barrel 10 which reciprocates through the packed gland.

To hold the glands and packing securely in the bushing, I employ a clamping member comprising the two hinged jaws 11 and 12 which freely swing on the threaded bar or bolt 13 as their pivot. This bolt is adapted to thread into one of the ears 5 Erica. V

of the bushing and has on its upper end a 'locknut l4 and clamp nut 15, the latter bearing upon the top edge of the jaws at their hinged joint. In Figs. 2 and 3 it will be seen that these jaws are provided'with curved portions 11"and 12 which fit around the barrel 10, but do not interfere with the movement of the barrel. At their ends the jaws are clasped by means of the yoke 16 which is fixed to the jaw 12 by the bolt 17 and detachablyconnected to the jaw 11 by the bolt 18. In Fig. 1 it will be seen that 'the longer jaw 12 is provided with a slot 19 near its end in which the bolt 17 is slidable, and by this means the yoke may be moved to clasp over the end of the shorter jaw 11, or moved outwardly to. free the jaws from each other. When the jaws are brought together they fit .about a threaded bolt 20 which is threaded into the other ear 5, and this bolt is also provided with a clamp nut 21 and lock nut 22. Thus, when the parts are assembled as in Fig. 1, the gland sections may be securely pressed down in the bushing by turning the clamp nuts on the bolts 13 and 20, and then these nuts may be locked against turning by the lock nuts 14 and 22. The jaws thus bear upon and hold the glands in the bushing forming an air and oil tight closed top or housing for the oil tube and preventing the escape of oil therethrough.

Above the packed joint or housing a similar but smaller'bushing 3 is screwed to the barrel 10 and'the gland sections 7 and 8 and clamping member 13 provide a tight joint for the cable 14 and provide a liquid tight joint. The cable of course may the pumping sinker has reached its desired depth, and then the cable may be clamped and held between the clamp member 13' as will be understood.v

In Figs. 1 and 5 the improved manner of fastening the socket 23 to the spread end pass down through-the packed gland until of separate strands 24 of the cable 14" per- 10, thus avoiding the usual necessity of cut- Q ting the socket from the cable before it can be passed through the barrel.

The socket is threaded externally to receive the sinker (not shown), and perforations are formed in the socket to receive the'unraveled end of-the-cable which is then leaded or babbitted to make a secure fastening.

The jaws of the hinged clamps may be opened to give access to the glands of the packing and the sectional construction of these glands facilitates the replacing and renewing of worn parts without recourse to the usual laborious proceeding, thus sav-,- ing considerable time and expenditure of energy, in attending to these duties.

What I claim is:-

The combination with an interiorly shoul-- dered oil Well tube provided with exterior perforated cars, a sectional packing gland in the tube, and threaded bolts in the ears,

of 'a pair of clamping jaws having a hinge ture.
