To all fro/icm t muy concern.'
Be it known that l? @Lann li. lnonoonic, a citizen of the llnitee States, residing at Eldorado, in the countyv of Butler and State of Kansas, have invented certain new and useful improvements in l@il-Saviiig Attachments, of which the following is a specication,
rThe invention relates to an oil well tubing appliance and more especially to the class of oil saving attachments for use with oil well tubing.
The primary object of the invention is the provision of an attachment of this character, wherein the oil within the well tubing sections, when being unscrewed or separated one from the other, will be trapped and conveyed back to the well, thereby eliminating the possibility of waste of the oil or vthe escape thereof during the uncoupling operation of the joints between the well tubing sections when removed from the well.
Another object of the. invention is the provision of an attachment of this character, wherein the construction. and arrangement thereof enables the placing of the about the oil well tubing at the joint to be uncoupled so that when separating the tube sections9 any oil contained therein will be collected and returned into the well, the mounting of the attachment being effected with despatch and any waste of oil is prevented when uncoupling the tubing sections for the cleaning thereof.
Ay further object of the invention is the provision of an attachment of this cha acter, wherein the oil-tight made from flexible material, is so connected with a frame for embracing the oil. well tubing section that in event the said bag becomes damaged or unfit for use it can be readily and easily detached and a new bag substituted, the oil escaping from the joints between the tubing sections when separated being conveyed through the bag back into the well, when the said tube sections are being withdrawn therefrom. sections of the wel] are generally filled with oil and when the same are taken apart above the well, the oil contained therein flows out and is wasted. The use of the attachment eliminates the waste or loss of the oil, and overcomes any disadvantages present in the use of apparatus or attachments heretofore employed for this purpose.
The tubes or Qther objects ofthe invention will be in part obvious and in part hereinafter pointed out.
The invention accordingly consists in the elements and arrangement thereof7 the construction of which will be exemplified in the following description and the scope of the application of the same indicated in the appended claims.
ln the accompanying drawings.
.Figure l is a fragmentary elevation of a well casing and cap, with the tube sections raised, showing the attachment constructed in accordance with the invention applied.
F ig. 2 is a sectional view taken approximately on the line 2-2 of Fig. l.
Fig. 3 is an enlarged end elevation of the bag frame.
Fig. l is a perspective view of the frame of the attachment with the bag removed and the door open7 the sections of the frame being separated.
Similar reference characters indicate corresponding parts throughout the several views in the drawings.
Referring to the drawings in detail, A designates generally a portion of the upper end of an oil well casing, having the conventional cap B through which are passed and raised the oil well pipes or tube sections @which are coupled or united through the medium of a separable joint l) of any ordinary' well-known construction. ln removing' or pulling the tubing from the oil well,
it is drawn out as a unit until several or more of the sections of the tubing or pipes project above or are elevated relative to the cap B of the casing A. and when the lowermost of the projected or elevated sections of said tubing are separated by uncoupling the joint 'D the oil contained in the tubingescapes therefrom at the separated joint and ordinarily is lost or wasted. To prevent the escape or the loss of the oil within `the tubing sections C when separated by uncoupliiig the joint D there is provided the oil saving attachment hereinafter fully described.
The oil saving attachment comprises a flexible fluid-tight bag or sack 5 which constitutes a conta-incr, the saine being greatly increased in size from one end to the other thereof, while suitably engaged with the smaller end of said bag or sack is a nipple of any approved form7 the same being detachably fastened to an inlet 8 projecting laterally from the cap B on the well casing A through the medium of a detachi able connection or coupling nut 9, yet said nipple 7 may be otherwise detachably engaged with the cap B if found desirable.
The wider or larger end 10 of the bag or saclr 5 is engaged with a frame structure constructed and arranged to lit over the coupling joint D between the lowermost sections of the tubing or pipeabove the well casing A. This frame structure comprises a pair of lower, inner and outer substantially half circular shaped clamping hoops 11 and 12 respectively, each having upstanding side bars or rails 13 between which and the hoops 11 and 12 is fastened the edge of the larger end 10 of the bag 0r sack 5, the said edge being secured, and the bars or rails 13 and hoops 11 and 12 being joined through the medium of counter-sunk screws or other like fasteners 1e so as to assure a non-leakable joint therebetween.
Carried by one of the bars or rails 13 of the frame structure is a swinging door 15, the same being supported on suitable hinges 16, movably connecting it to the frame structure, the door 15 being provided with caps 17 adapted to be engaged with suitable latches 18 carried by the bar or rail 13 opposite that to which the hinges are connected, thus it being seen that the door can be latched in closed position when the frame structure embraces the tubing and the latter with the door are in clamping relation tothe said tubing. On the closing of the door 15 upon the frame structure, the Well tubing C will be completely embraced at the end 10 of the bag or sack 5 so that upon separation of the sections of the tubing C at the joint D the oil within the tubing sections will flow into the said bag or sack 5, when said oil will be conveyed thereby bach into the oil well through the cap'B and casingA.
VThe particular construction of the frame structure enables the bag or sack 5 when the same becomes damagedV or unfit for use to be detached and a new bag substituted, as the screws or fasteners 14: are removable for this purpose.
lt is of course understood that suitable vpacking 1.9 is provided at the contacting g tting thelarger end of the bag around portions of the frame structure with the well tubing and also the door 15 so as to avoid leakage of oilV when flowing from the separating tube section, therebuzr eliminating any escape of oil or the wasting thereof when it is being conveyed through the bag 'or sack 5 back-into the oil well.
lt is of course understood that changes,
variations, and modifications of the Yinvention may be resorted to, without departing from the spirit thereof or sacrificing any of its advantages, these changes being allowed under the scope of the claims hereunto appended.
What is claimed'is:
1. An attachment of the character described, comprising a flexible fluid-tight baglilre element gradually increasing in size from one end to the other thereof, a coupling engagedin the smaller end of said element and adapted for connection with the cap of an oil well casing for communication with the latter, a frame detachably carrying the larger end of said element and constructed and arranged to permit the said larger end to lit about oil tube sections at the juncture thereof, and a door swingingly connected to the frame and having catches for fastening said door in closed position.
2. an attachment of the character described, comprising a duid-tight bag gradually increasing in size from one end to the other thereof, means at the larger end of the bag to close the same and having a swinging door, a nozzle fitted in the smaller end of said bag, and means for detachably connecting the nozzle with the cap of an oil well casing for establishing communication between the latter and said ba- An attachment of the c aracter described, comprising a fluid-tight bagrgradueoV ally increasing in size from one end to the vother thereof, means at the larger end of -the bag to close the same and having a swinging door, a nozzle fitted in theV smaller end of said bag, and means for detachably connecting the nozzle with the cap of an oil well casing for establishing communication between the latter and said bag, the means ture hereto.
