This invention relates to an elevator for oil well drilling stems and the like.
An important object of the invention is to provide a device of this character which may be engaged with the drilling stem at i any point, so that a broken stem may be separated from the fishing tool which is employed to remove the same from the well without the necessity'of completely with-' drawing the stem from the well.
A further object of the invention is to provide a device of this character which will operate not only as an elevator, but may a so serve as a casin head so that head of the casing.
A further object of the invention is to produce a device of this character which ma be readily and cheaply constructed, is rea ily applied to the stem and which will be durable and efficient in service.
These and other objects I attain by the construction shown in the accompan ing drawings, wherein for the purpose of i lustration is shown a preferred embodiment of my invention and wherein Figure 1 is a detail view showin an elevator constructed in accordance wit my invention applied to hold a drill stem which has just been raisediby a fishing tool Figure 2 is a similar view showing the elevator in use for hoisting the drill;
Figure 3 is a plan view of the elevator;
Figure 4 is a section on the lineH of Fi ure 3.
eferrin now more particularly to the drawings, 5) ing sections and 11 having coacting interdigitating lugs 12 through which a pivot 13 is directed tohingedl connect the sections to one another. Eac section has in that face thereof which confronts the other section, when in assembled relation, a semicircular groove 14, these grooves combining in the assembled relation of the sections to produce an opening .for the passage of the stem. Each section is further provided at each end thereof with extensions 15 and 16, the extensions 16 which are arranged adjacent the pivoted ends of the sections being offset transversely of the body was to provide space permitting the sections to be swung to the open position. Each section 10 and 11 has formed in the extensions 15 and 16 thereof openings 17, which align in the closed position of the sections, for the reclamp, the broken stem may e supporte from the e clamp is formed in two coactception of a sling or bail 18, by means of' which the sections may be connected to a hoisting apparatus, generally designated at 12. The extensions 15 are further provided w th openings 20 for the passage of a securng bolt, whereby these sections may be held in assembled relation. At the opposite side of its groove 14 from the cars 12, the section 10 is formed with a vertically extending groove 21 adapted to receive a similarly positioned vertically extending lug 22 formed upon the section 11. The side faces of the lug and roove are preferably beveled, so that by tightening upon the securing bolt 23, the lug is very rmly seated in the groove and any transverse strain upon the pivot 13 is prevented.
Each section 10 and 11 is formed in the base of its semi-circular groove 14 with a vertically extending dove tail groove 24, the bottoms of these grooves in the assembled relation of the sections converging downwardly. Within the grooves are arranged slips 25, the rear face 26 of which is sloped to conform to the slope of the grooves 24 and is formed as a dove tail for coaction with these grooves. The front faces of the slips 25 are preferably concavely grooved, as indicated at 27 and provided with transversel extending upwardly facing teeth 28 which are adapted to gripthe stem which is to be held. From the outer wall of each of the sections 10 and 11 to the base of the dove tail groove 22 at the center thereof are threaded openings 29 for the reception of bolts 30, the inner ends of which extend into vertically extending slots 31 formed in the slips 25 and thus serve to limit vertical movement of the slips within the grooves of the sections.
In the use of a device of this character, the broken drill stem supported by the elevator 32 is drawn upwardly until the stem below the elevator is exposed above the upper end of the casing 33. Theclamp is then applied to the stem and after being secured in position is seated upon the upper end of the casing 33 and the fishing tool and stem lowered until the slips 25 grip the stem. The fishing tool may then be disengaged from the stem and this stem will be supported by the clamp. After disengagement, if it is desired that the stem be hoisted from the hole, this may be accomplished by applying the bail 18 and connecting the same with the hoisting mechanism 19 when the clamp will act as an elevator;-
Since the construction hereinbefore set forth is capable of a certain range of change and modification without materlall de arting from the spirit of the inventlon, do not limit myself to such specific structure except as hereinafter claimed.
I claim: 4 V a In a clamp of the character described, a pa'ir of clamp sections having pro'ecting from the adjacent faces thereof inter igitating lugs throufgh which a pivot is p, adjacent faces 0 the sections having .verticall extending grooves for the reception of a dri stem, the ends of the body of the sections of the clamp having extensions, the extension adjacent the pivot being offset from the pivot to enable the sections of the clamp to be swung to open position, the extension at the opposite end of one of the sections having a vertically extendin rib and the corresponding extension of t e other of the sections having a roove, a securing element extended through t e last named extensionsfor fore ing the rib into the groove to thereby retaithe sections against transverse movement which would a ply strain to the pivot, there being dove ta grooves in the walls of the semi-circular rooves of the sections, slips mounted in said dove tail grooves and projectin into the semi-circular grooves and a three ed element extended through the wall of each section and havin its inner end extended into a slot forme in the associated slip to thereby limit vertical movement of the sli in the groove.
n testimony whereof I hereunto afiix my signature.
KENNETH DONLEY NEELY.
