CABLE GONNECTER.
Application filed June 21, 1926. Serial No. 117,498.
This invention relates to well drilling apparatus of the rotary type.
ell drilling apparatus of the rotary type employs a. drill secured to a drill pipe. It is well known that the drill occasionally breaks, also the drill pipe. When such breakage occurs, a costly procedure known as fishing must be resorted to. j
It is one of the objects of my invention to provide a device whereby the apparatus may be withdrawn from a well when the aforementioned breakage occurs.
Another object of my invention is the provision of an improved drill pipe, whereby the liability of such pipe to breakage is diminished.
With the foregoing objects in view, together with such. other objects and advan tages as may subsequently appear, this invention resides in the construction and arrangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a central vertical section of a drill pipe showing a rotary drill secured thereto at the bottom and showing further safety apparatus of my invention.
Figure 2 is a plan view of one section of a tie block employed in my invention.
Figure 3 is a section of the tie block shown in Figure 1 as taken on the line 3-3 of Figure 1, and shows the relation of the cable sections of the tie block.
Referring to the drawings for a more detailed description thereof, the numeral 5 indicates a rotary drill pipe comprised of a pair of adjacent sections 6 and 7 which are in alinement and which are secured together by a tubular member 8 which threadedly engages the inner surfaces of the sections 6 and 7 to hold these sections together.
An internal tubular member 8 provides a stronger pipe than would the external tubular joining member, and furthermore allows a drill pipe of uniform external diameter to be employed in the drilling operation. The latter feature is important since it desirable to have a uniform clearance between the outer surface of the drill pipe and the periphery of the well.
To the lower end of the drill pipe 5 is secured a rotary drilling member 10, or tool,
by threaded engagement. The drilling tool 10 has an extension or stem 12 at its upper end and this stem extends upwardly into the drill pipe 5. A swivel member 15 comprises a lower tubular portion 16, which is slipped over the stem 12. A washer 17 engages the upper surface of the tubular portion 16 of the swivel member. A nut 18 threadedly engages the upper portion of the stem 12 and is prevented from coming off the stem by cotter pin 19. A cable is provided, according to my invention. for lifting the drill and the drill pipe out ofthe well in case the drill pipe or the drill breaks while drilling. This cable is shown as secured to the swivel member 15 at the upper end of the latter, and the cable extends upwardly through the drill pipe to the surface of the earth. The cable is shown as being in sections, the sections herein shown being numbered 20 and 21 respectively.
The sections 20 and 21. of the cable are provided with loops 22 and 23 respectively. The loops 22 and 23 are secured together by means of a tie block 25. The tie block 25 comprises a pair of sections 26 and 27 which are each provided with arcuate grooves 28 and 29, as shown in Figure 2. Grooves 28 and 29 of each section of the block oppose each other and form circular grooves in which lie the loops 22 and 23 of the cable sections 20 and 21. The sections 26 and 27 of the block are secured together by threaded bolts 30 and 31, shown in Figure 3. These bolts pass respectively through the loops 23 and 22 of the cable sections.
twill thus be seen that when the drill pipe and the attached drilling tool are rotated, the swivel member 15 will not rotate, and therefore the cable will not be appreciably twisted.
Inspection of the drawing readily shows that it the drill pipe or drilling tool should break, both of them may be raised to the surface by means of the cable.
While I have described one embodiment of my invention, modifications thereof may be readily devised without departing from the spirit of my invention, and it is to be understood that such modifications come within the scope of the appended claim.
I claim p A block comprising two symmetrical sections with, :fiit'innertraces; each sectionhaving a pair of spaced symmetrical loopshaped grooves 01 uniformdepth terminat= ing in opposite ends of the section and co operating with the corresponding grooves of the other section for confining cable loops therebetween and threaded means extending through the two sections Within the loop areas for holding the sections together.
