"App1ica.tion filed Octpber 5, 1916. Serial No. 123,882.
Oklahoma, and GEORGE L. SKILLEN, a citizen of the United States, residing at Boynton, in the county of Muskogee and State of Oklahoma, have invented certain new and useful Improvements in Oil-Well Heaters;
and we do declare the following to be a'full, clear, and exact description of the invention, such as will enable others skilled in the.
artto which it appertains ,to make and use the same. v Y
Uur invention aims to provide a simple and inexpensive yet highly eflicient device to be lowered into oil wells for the purpose of heating and melting any substance therein which may have accumulated due to the prevalence of paraflinor mineral base. It is a well known'fact that the accumulation of such substance often so clogs the pump tubing as to ,render it necessaryto often remove the same for cleaning purposes, and furthermore, it accumulates on the oil sand and thus retards the flow of oil and sometimes checks it entirely. These difiiculties ,areover'come by the improved heater shown in the accompanying drawing which con stitutes a part of this application and in which therefrom in any preferred manner, one end of these coils being grounded to said tube while the other ends 5 thereof are electrically connected with-a feed wire ,6.
A pair of end rim" 7 are provided, the
,inner edges of these rings being reduced in thickness and received between the ends of the inner and outer tubes 1 and 2 in threaded engagement with said tube 1 by means of screw threads interengaging-the threads 3.
By reducingthe inner edges of the rings 7, ,inner and outer shoulders 8 and 9 are pro- .videdfsaid'inner shoulders being in contact with theends of the inner tube 1 while gaskets 10 are interposed between the ends of .tube 2 and shoulders 9 to prevent the entrance of fluid. A
The outer edges of the rings 7 are beveled both internally and externally as shown respectively at 11 and 12 to prevent them from lodging on collars and other joints of the Wei casing, the pump tubing and the sucker r0 One of the rings 7 is formed with a bore 13 which extends from one of its edges to the other and receives the wire 6 above described, this wire being insulated and being also passed through a tubular housing 14 threaded in the outer end of the bore 13,-
said housing having at its'upper end a packing gland 15.
For lowering the entire device. into the well and withdrawing it when required, the upper ring 7 is provided with a pair of eyes or the like 16 andbranches 17 on the lower end of a metallic cable 18 are secured to said eyes, said cable and branches cooperating .With the wire 6 in carrying the current for the coils 4: it being obvious that current entering said coils through the w re 6 will pass from said coils through the inner tube 1, the upper ring, 7, and the eyes 16'to the branches of said cable.
,By constructing the device in the manner shown and described, it may be easily and inexpensively manufactured and thus sold at a minimum cost. Regardless of this, however, it will be highly efficient and durable,
emphasis being therefore laid upon the general construction set forth although it is to be understood that within the scope of the invention as claimed, numerous changes may be made without sacrificing the principal advantages.
We claim:
1. An oil well heater to surround the pump tubing and sucker rods, said heater comprising a tubular electric heatingmemher open at both ends and beveled both externally and internally at its ends to prevent lodging on the joints of the well casing, the pump tubing, or the sucker rods, both the inner and outer sides of said heating member being smooth and free from projections.
2. .An oil well' heater to surround the pump tubing and sucker rods, said heater comprising an inner tube open at both ends,
one or more heating coils wound around 'said tube, an outer tube extending around tubing, or the sucker rods, the inner side of the inner tube, the outer side of the outer tube,'and both sides of the ring being smooth and free from projections.
3. An oil well heater to surround the pump tubing and sucker rods, said heater comprising an inner tube open at both ends and threaded externally at its ends, a heating coil or coils wound around said tube,
an outer tube surrounding said coil or. coils,
a pair of end rings whose inner edges are reduced in thlckness and recelvedbetween the ends of the inner and outer tubes in threaded engagement with one thereof, the outer edges of said rings being beveled both externally and internally to prevent lodging on the joints of the well casing, pump tubing, or sucker rods, one of said rings having a bore formed therethrough from one edge to the other, and one or more feed wires for the coil or coils passing through said bore,the inner side of the inner tube,
the outer side of the outer tube, and both sides of the end rings being smooth and free from projections.
In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
