UNITED STATES ARTHUR J. BOYTER, OF TEMPLE, TEXAS.
CASING-ELEVATOR.
Specification of Letters Patent.
Patented Nov. 8, 1921.
Application filed September 15, 1920. Serial No. 410,399.
To all whom it may concern:
Be it known that I, ARTHUR J. BOYTER, a citizen of the United States, residing at Temple, in the countyof Bell and State of Texas, have invented certain new and useful Improvements in Casing-Elevators,of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to casing elevators.
An important object of the invention is to provide a device for removing casings, plun gers and the like from wells which is capable of use with casings and plungers of varying diameters.
A further object of the invention is to provide a device of this character formed of a pair of hinged sections, each provided with a pivoted jaw together with a novel means for clamping the hinged sections about a casing.
Other objects and advantages of my-invention will become apparent throughout the course of the following description.
In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein like reference characters designate like parts throughout:
Figure 1 is a perspective view in elevation of a casing constructed in accordance with my invention;
Fig. 2 is a side elevation thereof in position upon a casing;
Fig. 3 is a sectional view taken therethrough, and
Fig. 4 is a plan view thereof.
Referring now more particularly to the drawings, the numerals l0 and 11 indicate coacting semi-circular sections. Section 11 has extending upwardly therefrom a flange 12 provided with outstanding ears 13 and 14 and the section 10 has extending upwardly therefrom a flange 15 embodying an ear 16 extending intermediate the ears 13 and 14 pivotally connected therewith by means of a pin 17. The opposite abutting edges of the sections are provided with means for locking the sections in the closed position comprising a flange 18 formed upon the section 11 in which is pivotally mounted a substantially rectangular yoke 20. The section 10 is rovided with a coacting flange 21 the side ace of which abuts the side face of the flange 18 of the section 11 when the sections are in closed position. This flange 21 has formed therein a slot 22 which alines of upstanding flanges 24 which, when the sections are in assembled arrangement, are diametrically opposed. Extending inter mediate the walls of each pair of flanges 21 is a pivot pin 25 upon which is mounted a bell crank lever 26, one arm of which 27 is arcuately curved longitudinally and concaved transversely, being provided upon the concave face with serrations 28, forming gripping teeth. To the other arm of each of the bell cranks 26 as at 29 is pivotally connected a bail 30.
These jaws or bell cranks are mounted upon the pivot pins 25 with the serrated faces 28 thereof disposed toward one another. l/Vhen it is desired to remove'thc casing the sections are opened by releasing the bail and subsequently closing the sections about the casing. ower is then applied upon the bails 30 causing the bell crank levers to shift about their pivots until the serrated faces 28 of the arms 27 thereof come into engagement with the sides of the casing, which, otecause of the construction of their faces, is gripped securely. When the bell crank levers 26 have been shifted to their limit further power applied will tend to elevate the casing.
It will be obvious that my device, by reason of the simplicity of its construction and the ease with which it may be applied to and removed from a casing or similar article, is particularly welladapted for use in this connection, and it will likewise be obvious that the construction as hereinbefore set forth is susceptible to some change without departing from the spirit of my invention. I accordingly do not limit myself to the specific structure hereinbefore set forth except as so limited by the subjoined claims.
Having now described my invention, what I claim is:
1. In a casing elevator a pair of pivotally connected sections combining to form an annulus, diametrically opposed jaws pivotally connected with said sections and having means for securing the sections about a casing, comprising a flange projecting upwardly from each of said sections and abutting when the sections are closed about a casing, a yoke transversely pivoted to one of said flanges, the other of said flanges being provided with a slot adapted for the reception of said yoke.
3. In a casing elevator a pair of pivotally connected sections combining to form an annulus, diametrically opposed jaws pivotally connected with said sections and having their opposed faces roughened, a bail pivotally connected with each of said jaws and means for securing the sections about a casing embodying a flange projecting upwardly from each of said sections and abutting when the sections are closed about a casing, and a yoke embodying side arms transversely pivoted to one of said flanges, said side arms being spaced apart a distance suflicient to receive therebetween said flanges, the other'of said flanges being provided with a slot adapted for the reception of said yoke.
4. In a casing elevator a pair of pivotally connected sections combining to form an annulus, diametrically opposed jaws pivotally connected with said sections and having their opposed faces roughened, a bail pivotally connected with each of said jaws and means for securing the sections about a casing comprising, a flange projecting upwardly from each of said sections and abutting the other of the flanges when the sections are closed about a casing, a yoke transversely pivoted to one of said flanges, the other of said flanges being provided with a horizontal slot adapted for the reception of said yoke, said flanges being provided in the upper surface thereof with coacting notches adapted to receive said yoke when in the vertical position.
5. In a casing elevator a pair of sections adapted to be combined to form an annulus, diametrically opposed gripp ng jawspivotally connected with said sections, meansfor causing said jaws to move inwardly to engage a casing and means for securing the sections about a casing embodying a substantially radial flange projecting upwardly from each of said sections at coacting marglnal edges thereof, the adjacent faces of said flanges abutting when the sections are assembled about a casing, a yoke transversely pivoted adjacent the lower end of one of said flanges and embodying spaced side arms adapted to receive therebetween said flanges, the other of said flanges being provided with a horizontal slot allning with the pivot ofsaid yoke and through which said yoke is adapted to extend, said flanges being provided in the upper surface thereof with coacting notches adapted to receive said yoke when in the vertical position.
6. In a casing elevator a pair of sections adapted to combine about a casing to form a continuous ring, means for securing said sections about a casing, diametrically opposed pairs of spaced flanges extending upwardly from said sections, a pivot pin mounted in each of said flanges, a bell crank lever mounted upon each of said pivot'pins and embodying an arm which. is arcuately curved longitudinally and concaved transversely said arms being provided u n the concave face thereof with serrations orming gripping teeth, the serrated faces of said arms being opposed and a bail pivotally connected with the other arm of each of said bell cranks.
7. In a casing elevator, a pair of pivotally connected sections combining to form a casroughened, one of said jaws being pivotally mounted and being adapted for attachment ing receiving yoke, opposedjaws carried by said sections and having their adjacent faces to a traction element, and means for securing to form an annulus, opposed jaws pivotally connected with said sections and having their adjacent faces roughened, each of said jaws being adapted for engagement with a traction element, and a yoke pivotally connected to the free end of said sections and adapted to engage the other of said sections to secure the sections together about a casing.
In testimony whereof I hereunto aflix my signature.
