OIL WELL HEATER Filed Oct. 20, 1927 2 Sheets-Shet 2 gnvantoz J fill/flier w T w W abtomeq Patented Nov. 19, 1929 JOHN A. MILLER, OF CHICAGO, ILLINOIS OIL-WELL HEATER Application filed October 20, 1927. Serial No. 227,607.
This invention relates to new and useful improvements in oil well heaters.
My heater may be used in oil wells where production has decreased, by lifting the pump and inserting the heater, which can be put in action at once. After the heater has been in operation four or five hours, the heat will be so great that paraffin easily yields. For wells where the paraffin runs high and also for wells where the oil is heavy to pump, the heater can be left in the well at all times and is easy to control.
With the foregoing and other objects in view that will appear as the nature of my invention is better understood, the same con sists in the novel features of construction, combination and arrangement of parts illustrated in the accompanying drawings and more particularly pointed out in the ap- 2 pended claim.
In the accompanying drawings, which are for illustrative purposes only and are therefore not drawn to scale:
Figure 1 is a side elevation, partly in section, of an oil well heater embodying my improvements.
Figure 2 is an enlarged vertical longitudinal section of the oil well heater.
Figure 3 is a horizontal section, taken on line 33 of Figure 2.
Figure 4 is a vertical transverse section, taken on line 4 4 of Figure 3 and Figure 5 is a horizontal section, taken on line 55 of Figure 2.
Referring to the drawings for a more particular description of my invention and in which drawings like parts are designated by like reference characters throughout the several views, my heater comprises a Shelby tubing body 1, whose bottom 2 is welded on and whose top 3 is in the form of a cap screwed into the upper end of the body. The cap 3 is provided with a safety valve 4 to discharge any gas or steam that may accumulate from moisture inside the body by sweating and directly opposite the safety valve is a packing box 5 for the purpose of having the B. X. cable packed tightly, in order that no oil or water can enter the heater.
Mounted interiorly of the hollow body 1 is a heating unit 6, comprising four or more glow-bars 7, which are arranged in concentric relation with the body and properly insulated This is accomplished by arranging a pair of longitudinally spaced asbestos insulating discs 8 within and adjacent opposite ends of the body 1 and connecting said insulating discs together by a central rod 9 whose threaded ends 10 extend through the aforesaid discs and are securely connected thereto, by the clamping washers 11 and fastening nuts 12 and 13. Tubular supporting heads or sleeves 14 are carried by the insulating discs 8 and provided with sockets 15 to receive the opposite ends of the glow-bars 7. An insulating disc 16 is also interposed between the bottom 2 of the body 1 and the adj acent end of the central rod 9, the purpose of therefrom.
which will be apparent.
From the foregoing description taken in connection with the drawings, it is thought that the construction, operation and advantages of my invention will be readily understood without requiring a more extended eX- planation.
Various changes in the form, proportions and minor details of construction may be resorted to without departing from the principles or sacrificing any of the advantages of my invention as defined in the appended claim.
Having described my invention, what I claim as new and desire to secure by Letters Patent, is
from the body.
In testimony whereof he affixes his signa ture.
JOHN A. MILLER.
