J. 5. SPENCER OIL WELL TUBE SCRAPER Filed Jan. 1927 Inventor Patented Dec. 27, 1927.
UNITED STATES JOHN SILOS SPENCER, 0F P AMPA, TEXAS.
OIL-WELL -T'UBE SGRAPEB.
Application filed January 3, 1927. Serial No. 158,808.
The present invention relates to a devicefor scraping the tubing of Oll wells and the like when pulling rods thereby eliminat ng what is known in the trade as a tublng job, and steaming tubing.
Another important ob ect of the 1nve nt1on lies in the provision of a scraper having a structure which will fold up when lowering the scraper with the rods in the tublng and which will unfold on the upstroke as the scraper is raised. There may be several of these scrapers used in a string of rods to prevent a jam dependlng, of course, on the condition of the well.
The device is designed also for use on tools, usually, on a clean-out string. For
example, when agitating tools should be pulled to the top of the caslng once or more, each shift depending on conditions of the well, the use of this scraper frees the casing of pal-affine and the like. The scraper may be used in a string of sucker rods or a string of tools above or below the ClI'lll stem or any point in a strainer sucker rod.
Another important object of the lnvention lies in the provision of a device of this nature which is simple in its construction, efiicient and reliable in use, inexpensive to manufacture, strong and durable, and otherwise well adapted to the purpose for WlllCh it is designed. 1
With the above and numerous'other objects in view the invention resides in certain novel features of construction, and 1n the combination and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawing:
Figure 1 is a side elevation of the device embodying the features of my invention,
Fig. 2 is an enlarged sectional view taken substantially on the line 2-2 of Fig. 1 looking downwardly.
Referring to the drawing in detail it will be seen that the numeral 5 denotes an elongated shank which is provided at its upper end with a threaded tapered pin 6 for making-a joint with sucker rods or tool rods and its other end with internal threaded boxings 7 to receive the pins of sucker rods or tool rods. Portions 8 of the shank adjacent both ends are squared so that a tool may beengaged therewith for screwing and unscrewing the device in a series of rods.
An intermediate portion 9 of the shank is of an elongated squared formation and the por- -tion immediately there-below is enlarged to receive the squared portion 9 to slide upwardly thereon. The portion 13' immedi ately above the portion 9 is enlarged and the bottom thereof has a V-shaped shoulder 14. The disk 11 is formed in two sections A and B hinged together as at C so that when the device is being let down in the tubing it will take the dotted line position as shown in Figure l and will brake so as not to scrape the interior wall of the casing but as the device is moved upwardly the disk will unfold resting on the shoulder of the portion immediately below the squared portion 9 and the supporting wing 10 as is clearly shown in Figure 1 and will scrape the interior surface of the tubing of all paraffin and the like.
It is thought that the construction, utility, and advantages of this invention will now be apparent to those skilled in this art without amore detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention what I claim as new is 1. A. tubing scraping device of the class described including an elongated shank having means at its ends for attachment in a series of rods and having its intermediate portions reduced to form at the upper end thereof a. V-shaped shoulder and at the lower end thereof another shoulder with wings radiating outwardly therefrom, a disk having a square opening slidable on the square portion, said disk being formed in hinged sections.
2. A tubing scraping device of the class described including an. elongated shank having means at its ends for attachment in a series of rods and having its intermediate portions reduced to form at the upper end thereof a V-shaped shoulder and at the lower end thereof another shoulder with wings radiating outwardly therefrom, a' disk having a square opening slidable on the square portion, said disk being formed in hinged sections, portions of said shank adjacent the ends thereof being squared for engagement.
by tools.
3. A scraping device of the class described for use in oil well tubing comprising an elongated shank, an intermediate portion of the shank being reduced, a disk having an opening to slidably receive the reduced portion of the shank, said disk being formed in sections.
4. A scraping device of the class described for use in oil well tubing comprising an elongated shank, an intermediate ortion of the shank being reduced, a disk aving an opening to slidably receive the reduced rtion of the shank, said disk being forme in' sections, the portion of the shank immediately below the reduced portion being provided with alternately radiating supporting wings.
In testimony whereof I afiix my signature.
JOHN SILOS SPENCER.
