UNllTED STATS HENRY E. DEAVERS, OF LGS ANGELES, CALIFORNIA.
WELL-CASING STR-AGHTENING TOOL.
Application filed November- To all whom t may concern: n
Be it known that l, HENRY E. Dnavnns, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in ll/ell-Casing Straightening Tools, of which the following is a specification.
My invention relates to a rotary tool for restoring to its normal condition well casrolls may be readily removed therefrom andY new ones readily substituted as occasion demands, and to provide means for support-V ing the rolls in operative position should their bearing pins become accidentally broken during the operation of the tool.
It will be understood that l do not limit myself to the precise construction herein described and illustrated, but I may resort to various changes in the mechanical construction within the scope of my appended claim, and without departing from the spirit of my invention.
I accomplish the above objects by means of the device herein described and illustrated in the accompanying drawings forming a part thereof, in which:
`Figure 1 is a vertical section through a drilled well with the casing in position, the lower portion being shown as deformed, 'the tool being in side elevation above the deformed portion of the casing.
Fig. 2 is a side elevation of the straightening tool.
Fig. 3 is a transverse section taken on line 3-3 of Fig. 2.
Fig. d is a central vertical section through the tool taken on line 4:-1 of Fig. 5.
Fig. 5 is a top plan view of the tool.
Fig. 6 is a side elevation of a modified forni.
F ig. 7 is a central vertical section of t-he form illustrated in Fig. 6.
Fig. 8 is a transverse section taken on line 8-8 of Fig. 7.
ln lowering into position oil well casing,
13, 1923. Serial No. 674,495.
the same is often bent out of shape by rea-` son of unusual or rocky geological formations, and when such accidents occur the casing usually has to be withdrawn from the well in order that the drilling operations may be continued.
y means of my present invention, when such accidents as above recited occur to a section of casing, the casing need not be withdrawn from the well, as my tool ican be readily lowered into the casing to the point of deformation and operated to restore the same to normal condition.
Referring now more specically to the drawings wherein are exhibited an embodiment of my invention, 10 designates the frame portion of the tool, provided with a centrally disposed bore ll for the passage therethrough of water during a straightening operation. The lower end 12 of the frame is truste-conical in form, having a cent-rally disposed cylindrical portion 18 extending upwardly from the base of the fuiste-conical end, its cylindrical wall tapering upwardly as at lll, the purpose being described further on. l he extreme upper end of the frame portion of the tool terminates in a threaded tapered pin 1 5, and at the base of pin 15, is formed an annular bearing flange 16. Disposed around the cylindrical tapered portion 1? of the frame and spaced equally apart, are a series of roller bearings 17, rotatably mounted on bearing pins 18, provided with upper headed ends 19 and reduced lower ends 20, that engage circular cavities 21 formed in the upper surface of the base portion of the frusto-conical end. Bearing pins 18 pass through circular openings 22 formed in the flange 1G, the headed ends 19 engaging circular seats 23 formed at. the upper ends of the openings, the lower end of drill pipe 24 when connected to the tapered pin holding the pins from rotation. In order to readily remove the tapered pins when they become worn or broken, l have provided elongated apertures 25 extending from each cavity 21 through the conical end of the tool in order that a pin or other tool may be introduced therein to force the pins 17 out of engagement with their seats.
Should any undue or unusual strain be imposed on the roller pins 18, I have provided downwardly extending lugs 26, preferably formed integral with the flange 16 of the frame. the side faces of each lug` being` concaved longitudinally and of a depth to permitthe vfree rotation ,of thevarious rollers. From this construction 'it will be apparent that should a pin become brokenor bent during the operation ofthe device, the lugs 26 will prevent a displacement of the rollers.
In Figs. 6, 7, and 8, I have illustrated a modified form of casing straightener, in which the frame portion is exactly lthe same as in the preferred form, the rollers 17 being ofthe sametapered form anddisposed inexactlyl the same. manner, the only change residing in the frusto-conical end of the tool, which is providedwith-a Vplurality of pairs of taperedrollers, designed to impart a rolling action to the extreme end of the tool when the casing is badly deformed.
The Vsurface ofthe frusto-conical end is provided with recesses 30 extending downwardly Vfrom the' base or flange portion 12 of the end of the tool and` `terminating adjacent `the lower end thereof, and arranged in pairs and disposed between the rollers 17 mounted thereabove, as clearly shown in Figs. 6 and 8 of the drawings. By disposing the recesses formed in the surface 0f the .frusto-conical end ofthe tool between the rollers 17, a sufficient surface is provided to form apertures 25 utilized for removing worn 4or broken rollers 17 asin the preferred form. The annular edge of the base or `top portion of the frusto-conical tool end is provided 'directly above each recess 30 with vertically disposed concavities 31, the top wallV of lthe =recesses '30 having apertures 32 through which pass the headed bearing pins 33 of the tapered rollers' 34, the. lower ends ofthe pins seating in circular recesses 35 formed in the bottomwall 36 of each recess, the apertures 25leading from the bottom wall ofthe recesses tothe outer surface of the frusto-conical end.
InFig. 1, Ihave illustrated 4an applica` tion of my improved casing straightener, the casing 87 being shown deformed as at 38 by the rocky-formation-.of the wall of the well. From the above illustration it will be observedrthat theitool is secured to the lower end of a rotary drill pipe 39, the end 12 en- Agagingthe -wallsofthe deformed casing.
On a rotation of the tool by means ofthe usual rotary mechanism `(not shown), `euid 12 of the tool will gradually press'the deformed wallV outwardly so thatthe tapered rolls17 mounted thereabove willV engagejthe interior wall, an'd completely force or ross the casing into its normal or. original orm,`
`in connection with myitool, the deformed wall of the casing is subjected-to a rolling action, the metalbeing expanded equally without undue strains, and Without injury or breakage thereto.
That I claim is:
In a devicer of the class.'described, a substantially cylindrical frame having a cone shaped lower end and a threaded upper end, a plurality of tapered anti-frictionmollers mounted in said frame intermediate its upper and lower ends bearing lugsformed on said frame, a lug between each of said rollers and its adjacent roller, and a plurality of. tapered anti-friction rollers `mounted on the surface ofthe cone shaped end of said frame. y
In witness that 'I claimtheforegoing I have hereunto subscribed my name this' 16th day of October, 1923.
II.Y E., DEAVERS.
