HEATER FoR OIL-WELLS.

SPECIFICATION formizig part of Letters Patent N0. 760,304, dated May 1'7, 1904.

Application as October 24, 1903.

To all whom it may concern:

Be it known that I, J osErHC. BUTLER, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Heaters for Oil- Wells, of which the following is a specification. i

This invention relates to certain improvements-in heaters, such as are more especially designed for use in connection with oil-wells or the like for heating the same sufficiently to prevent the hardening or solidification of parafiin or similar solid and semisolid hydrocarbons, which are otherwise apt to collect and clog the suction-pipe; and the object of the invention is to provide a device of this general character of a simple andinexpensive nature and of a compact and durable structure which is capable of being readily transported from one well to another, so as to be adapted for use in heating a number of wells successively.

The invention consists in certain novel features of the construction, combination, and arrangement of the several parts of the improved heating apparatus whereby certain important advantages are attained and the device is made simpler, cheaper, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In the accompanying drawings, which serve to illustrate my invention, Figure 1 is a general view, drawn to a small scale and repre senting, somewhat diagraphically, an oil-well provided with a heating apparatus constructed according to my invention; and Fig. 2 is a sectional view, drawn to a larger scale and show-, ing certain features of construction of the heater located in the well. Fig. 3 is a plan view showing the improved heater seen in Fig. 2. Fig. 4 is a sectional detail view showing I the water connections at the upper ends of the'feed and return pipes.

As shown in the views, a represents the well, and b the casing thereof, commonly formed from metal pipe, while 0 represents the suction-pipe through which the oil iswitl1- Serial No. 178,340. (No model.)

drawn from the well. In Fig. l the central portion of the well is broken out for lack of space.

The improved heating apparatus constructed according to my invention comprises a heater-in the form of a closed drum or receptacle adapted for location at the bottom of the oil-well a and means for supplying hot water or similar heating medium to said heater and comprisingfeed and return pipes extended in the well and connected at the ground-level with a water heating and pumping apparatus, and in the accompanying drawings I have illustratedthe heating drum or receptacle as being made in circular or cylindrical form,- with upper and lower ends or heads 1 and ,2, each formed from cast metal in circular form with a marginal interiorly-screwthreaded flange 8, with which flanges of the respective upper and lower heads 1 and 2 are engaged the screw-threaded upper and lower ends of the peripheral portion 1 of the drum or receptacle. lower head 2 is formed with a circular opening of a diameter sufficient to receive the suctionpipe 0 of the oil-well, and said circular opening is surrounded by an upwardly-extended annular flange 5, interiorly screw-threaded to receive the threaded lower end of a pipe-seetion 6, the interior diameter or bore 7 of which forms a passage vertical in the drum and through which the suction-pipe 0 is adapted to At one side of its central portion the extend. The upper end of the pipe-section is also exteriorly screw-threaded to receive and engage screw-threads on an annulus 9, having at its upper portion a head 10, adapted 'toreceive a tool or wrench where by it maybe turned; and also provided at its lower end with exterior screw-threads whichare adapted to engage:corresponding threads on a flange 8 8 of the upper head 1 will of course correspond in location to the flange 5 of the lower head 2. In this way it will be seen that the heating-drum may be made in a very inexpensive and simple form and 1s capable of beof the drum.

pipes it will be seen that the water is drawn,

ing readily repaired; but I do not wish to be understood as limiting myself to the employment of this detailed structure exclusively, since it is evident that the drum may be made in-various other ways without material departure from the invention.

At the side of the drum opposite to the passage 7 produced in the pipe-section 6 for the suction-pipe 0, I provide the upper head 1 of the drum with an opening surrounded by a screw-threaded flange 8, with which is engaged the threaded lower end of the water discharge or return pipe 11, which is extended vertically in the oil-well and is adapted for conveying the water from the drum upward in the well to the ground-level and for returning itto the heating and pumping or forcing means, as will be hereinafter explained, and within the said return-pipe 11 is inclosed the water supply or feed pipe 12, which is, as shownin'the drawings, of an exterior diameter less than the internal diameter or bore of the return-pipe 11, whereby an annular space or passage 13 is produced within the returnpipe for the upward flow of the water from the drum. In this way it will be seen that the water traversing this annular passage 13 will form a jacket surrounding the supply or feed pipe 12, whereby the same will to a certain extent be protected and prevented from becoming unduly cooled, so as to disadvantageously effect the operation of the apparatus. The lower end of the return-pipe 11 is arranged at the flange 8 and is not extended within the drum; but the lower end of the feed or supply pipe 12 is extended down within the drum to a point near the bottom thereof, as shown in Fig. 2, and may be rested upon asupport 14, if desired or necessary, integral with and extended up from the lower head 2 By this arrangement of the into the return-pipe from the upper part of the drum, while the water is fed into the drum at the lower part thereof, whereby the hot water supplied to the drum is caused to circulate through the same before being discharged therefrom,'so that as much as possible of the heat of the water will be radiated from the drum to keep the oil and other substances at the lower part of the well sufficiently warm to prevent the solid constituents from congealing and clogging the suction-pipe 0. At the ground-level the upper ends of the return-pipe 11 and ofthe feed-pipe 12 may have connection in any desired way with the water heatingand pumping or forcing means; but I have herein shown the upper end of the return-pipe 11 as having screw-threaded connection with a nipple 16 at the baseof a shell 15, through which the feed-pipe 12 passes in an upward direction, said feed-pipe 12 having its upper end screwed through a nipple 17 on the shell and having above the shell a connection, as seen at 18, with the pump or other water-forcing device 19, which is in turn supplied with hot water by means of a pipe 20 leading from a water-heater 21. -From one side of the shell 15 projects a nipple 22, with which is connected a pipe 23, leading also to the heater 21, so that the water supplied from the drum at the bottom of the well byway of the return-pipe 11 to the shell 15will be discharged by pipe 23 'to the heater, and at the same time the hot water from the heater will be forced by the pump through pipe 18 and down the feed-pipe 12 to the drum for heating the oil and other substances in the well. I havev also shown a perforated cover 24 extended across the mouth of the well with its perforations adapted for the passage of the suction-pipe c and of the combined feed and return pipes of the heating apparatus.

The connections of the pipes 18 and 23 with the heating and pumping devices will be, by preference,readily detachable, so that the several parts of the apparatus may be readily separated to permit of conveniently removing the said heating and pumping devices on the truck w (seen in Fig. 1) from one well when no longer needed for use and of transporting the same (said heating and pumping devices) to another well,to which they may then be readily applied." In this way a single apparatus may be made to serve several or a number of wells to keepthem in proper order and prevent clogging or choking of the suction-pipes by the solidified hydrocarbons; but by preference I transport nothing but said heating and pumping devices (seen on the truck in Fig. 1) from one well to the other, leaving the remainder in each well.

The improved heating apparatus constructed according to my invention is of an extremely simple and inexpensive nature and is especially well adapted for use, since it is capable of being manufactured at but slight cost and may be readily transported from one well and quickly and effectively applied for use to another well and it will also be obvious from the above descriptionthat the device is capable of considerable modification without material departure from the principles and spirit of the invention, and for this reason I do not wish to be understood as limiting myself to the precise form and arrangement of the several parts of the device herein set forth in carrying out my invention in practice.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An'apparatus of the-character described comprising a water-receptacle in the form of a closed cylindrical drum adapted for location at the bottom of an oil-well and having at one 7 side of its central portion a vertical passage extended through it to receive a suction-pipe, a return-pipe connected with the upper part of the drum at the side opposite to said passage, afeed-pipe inclosed in the return-pipe and having its lower end extended down in the drum adjacent to the bottom thereof and means for supplying hot Water to said pipes.

2. An apparatus of the character described comprising a closed receptacle for containing a heated medium and adapted for location at the bottom of an oil-Well and means for heating and circulating a medium to and through said receptacle and comprising a return-pipe extended in the Well and a feed-pipe inclosed Within said return-pipe.

3. An apparatus of the character described comprising a Water-receptacle in the form of a closed cylindrical drum adapted for location at the bottom of an oil-Well and having at one side of its central portion a vertical passage extended through it to receive a suction-pipe,
