The primary object of the invention is to supply the water well drilling industry with an urgently needed tool for handling plain end well casing, a type universally used in well bores of large diameter.

This tool or apparatus, as designed, will accommodate any size well casing with an exact fit, serving both as elevator and spider and will eliminate the need for the cumbersome, conventional spider and the usual practice of welding on lugs or burning holes in plain end casing and lowering in well by means of bar and chain, wire loops, or some other improvised method.

The complete apparatus comprises a duplicate pair that serves alternately and in sequence as elevator and spider for each section of casing as it is attached to top of preceding section, as by welding, and lowered in well bore. Since the two units of the apparatus are essentially identical, each containing in its embodiment all of the components and accessories for serving as elevator or spider, only one will be shown in the drawings and will hereinafter be referred to as an apparatus.

The frame of apparatus consists of a plurality of circular, hinged segments that encircle casing and is tightly secured around casing by means of an adjustable latch. Each frame segment is equipped with an automatic, spring action casing slip. The incline bearing surface on frame segment and incline bearing surface on slip coact to force slip to grip and hold casing when stress is applied to lifting bail.

The apparatus is accommodated to different size casing by adding, dropping, or exchanging frame segments, which are cast in more than one length, then when x number of segments lap or fail to reach around casing, one or more segments are exchanged for shorter or longer segments, as the case requires, and the adjustable latch will compensate for any lack in exact fit.

The foundation for the operation when using this combination apparatus may be a rotary table, casing sills with a section of steel plate or some other flat surface that will support the weight of a string of casing. The energy for operation is supplied through the usual draw works, block, lines and hook, which is attached to lifting bail to raise and lower casing in well bore. One unit of apparatus picks up a section of casing, which is lowered in well bore to a point where apparatus rests on foundation and becomes an acting casing spider by gripping and holding while the other unit of apparatus picks up the next section, which is to be attached to top of preceding section, as by welding; then the bottom apparatus is released and the casing lowered further in well, to a point where this unit rests on foundation and becomes the acting spider. This routine is continued until all casing has been lowered into well bore. It will be observed from the foregoing that the two identical units of apparatus alternate as elevator and spider, hence, a combination tool.

The invention may be more readily understood by referring to the accompanying drawings and the description thereof, and whereas:

FIG. 1 is an oblique plan view of the embodied apparatus encircling a section of metal well casing;

FIG. 2 is an exploded sectional view, showing mechanism of certain essential components of the invention.

Referring to FIG. 1, the casing 10 is a section of metal well casing, which is to be lowered in well bore (not shown) by means of lifting bail l1 and draw works (not shown) to a point where apparatus rests on foundation, (not shown) which may be a rotary table or some other suitable foundation. The upper portion of casing 10 is encircled by the embodied apparatus, comprising multiple hinged frame segments 14 and two latch segments 25. Segments are interconnected by meshing lugs 21 with ears 20, which aligns opening in 21 with opening in 20 into which hinge bolt 12 is inserted and secured by nut 13. Ap-

paratus is adapted to be secured around around casinfi 10 by Inserting latch bolt 32 in opening 23, seating bolt hea 24 m bell seat 23, grasping hand hold 33 and swinging latch bolt 32 into slot 35, then tightening nut 31 on washer 34, forcing washer 34 into bell seat 23. Slip mechanism is more clearly shown in FIG. 2, wherein slip pin holds tension on slip activating spring, which is seated in bore hole 28 and secured by metal plate 17 and set screws 16. Metal mandrel 22 (a frustum of a cone) is babbited on end of lifting bail l1 and anchored in slotted, tapered opening 18. Set screw 19 holds mandrel in place when bail is relaxed.

Referring to FIG. 2, lifting bail 11 has metal mandrel babbited to lower end and is to be anchored in slotted, tapered opening 18 for lifting and lowering apparatus. Frame segments 14 are interconnected by meshing lugs 21 with ears 20, aligning openings 30 into which hinge bolt 12 is inserted and secured by nut 13. Spiral spring 27 is inserted in inclined, elongated bore hole 28, then when slip 15 is lowered into operating position, spline 37 engages spline 38, slip pin 36 enters bore hole 28 compressing spring 27. Tension is kept on spring 27 by means of metal plate 17 over slip pin 36, secured by set screws 16 in screw holes 26.

The vertical depth of the slotted spline 38 being greater than the vertical width of spline 37 and the incline in bore hole 28 will leave slip 15 free to move outward and downward to grip and hold casing. The tension created on spring 27 when slip 15 moves downward to grip casing 10 will automatically return slip 15 to its original position when latch is released. Since the incline of slip bearing surface is equal to incline 39 of frame segment 14, slip 15 will remain vertical at all times.

lclairn:

l. A combination casing elevator and spider and method, for lowering casing in well bores and removing same therefrom, comprising a duplicate pair; each consisting of a plurality of interconnected, circular hinged frame segments of varying lengths, with inclined, splined slip bearing surfaces, there being an inclined, elongated bore hole for slip activating spring and splined slip pin; casing slips with groove gripping surface, inclined bearing surface and spline connecting slip with slip activating pin; spiral spring seated in inclined, elon gated bore hole, and metal plate secured with set screws to hold slip in place and tension on spring; two latch sections or segments, which are a part of the frame, and latch bolt with a threaded portion, a washer, a nut, a hand hold, spherical seating surface and bell seats for bolt head and washer; there being a slot in latch segment to receive latch bolt when closing apparatus around casing, there being a vertical slot and ta red opening in each frame segment as optional anchor position for lifting bail.
