SWIVEL ROPE SOCKET.

Application led March 22, 1926. Serial No. 96,588.

This invention relates to a swivel rope socket, especially adapted to be used in well drilling operations for connecting the rope or cable to the drilling tools.

5 In carrying'on operations of this kind, the rope rapidly becomes worn where it enters the swivel, so that it is necessary about every other day to withdraw the tools from` the well, cut off the babbitted end of the rope,

lo and make a new end. In order to do this, with the sockets now generally used, it is necessary to disconnect the toolsand pull the en'd'of the rope through the lower end of` This involves a great deal ofV the socket.

and expense, mud, water and drillings will get into the threads, and unless greatV care become mutilated, so that the tools will often become detached while drilling.

ly stated, is to avoid the above mentioned difficulties by providing a practical construction soithat the rope may be provided with a new end without disconnecting the tools from the socket, and more specifically to provide a socket in which the end of the rope with the swivel attached may be readily removed or inserted through the upper end of the socket. v so The specific construction of the invention and the advantages resulting therefrom will be more fully explained in connection with the accompanying drawing .illustrating the saine.`

' In the drawing Figure 1 is a central longitudinal section through the socket showing the same connected with the rope.

lFigure 2 is a similar view illustrating the process of attaching the socket to the rope.

Figure 3 is atransverse section taken on the line 3-3 of Figure 1.

Figure t is a transverse section taken on the line 1 4 of Figure 1. Figure 5 is a transverse section taken on the line 5-5 of Figure 2.

Figure 6 is a perspective view of one of the bushing sections.

Figure 7 is a view similar to Figure 3, but showing a modified bushing.

Figure 8 is a view similar to Figure `5, but showing the sameform of bushing as that illustra-ted in Figure 7 is exercised the threads willy The object of the present invention, broad-- As illustrated in the drawing,the invention comprises a barrel or socket member 10, formed at its lower end kwith a tapered threaded recess V11 to which the tools are adapted to be connected. A cylindrical cavity` 12 is formed within the socket member 10, and is for wash out openings 13. The upper end o f the cavity 12 merges into a tapered p0rtion 14, and the upper portion 15, which extends to the upper end of the socket member, is also cylindrical, but of less diameter than the cylindrical portion 12.

he rope or cable 16 is spread at its lower end and babbitted in the usual manner, as shown at 17, within the swivel mem-ber 18. lhe outer surface of the swivel member 18 is cylindrical, and of approximately the same diameter as the cylindrical bore 15, so that it may be readily passed therethrough. The rope 16 above the swivel member 18 is adapted to be surrounded by a .bushing which, in the form illustrated in Figures 1 to 6 inclusive, is madeV up of two equal sections 19. Each of these sections is made up of a Vcylindrical portion 2O with a flared lower end 21, and when the sections of the bushing are Iassembled, the flared lower portions 21 wedge portion V111 of the socket cavity, while the cylindrical portions`20 iit within the bore 15, and extend upwardly somewhat beyond the end of the socket member, as shown in Fig ure 1. The bore through the bushing is of sufficient. diameter to permitthe rope 16V to slide freely therein. The upper ends of the bushing sections 19 are formed with a cir- -cumferential channelV 22 adapted to receive a spring clip 28, which holds the sections of the bushing in assembled relation.

In connecting the rope with the socketmember, the end of the rope is first inserted in the swivel member 18 and babbitted. The swivel member through the bore 15 into the cavity 12. The rope, where it passes`through the bore 15, may then be deflected, first toward one side, and then toward the other to permit the in sertion of the bushing sections 19 one bv one as illustrated in Figure 2. The lower flared portions 21 of the bushing sections have their opposite edges rounded, as shown at 24, so that they will notqbe too wide to closed at its lower end, except 18 is then insertedy into the tapered the rope,

circulation of water through the cavity 12, so that the latter will be kept clean.

After the bushing sections have been in- Y serted. into the cavity 12, and rest up'on the' upper end of the swivel member 18, the latter is drawn upwardly,and the bushing is drawn into the position shownin Figure I, and the clip 28 is applied. A pin 25may. then be inserted transversely oit the socket, so as to prevent any possibility of the' busli-A ing sections from being jarred out of their seats. c

'Instead of making 4the'bushingv in two sec! tions, it maybe made in three sections, as indicated `'atfZG in Figures 7 and 8. Infsuch case, the threev sections are assembled by the same method as that used vincase of a twoV` section bushing; i

In order to disconnecttherope from/the" socket when it is :necessary to` make a -new end, the socket is drawn up and suitably secured above thesurfaceof the:grounds.' The pin `25 may/then :beknocked out, rope vlowered until'ftlie savivel member 18 rests upon the bottom of the socketlQ.

The swivel lmember 118 fisithen'y lowered sufficiently so vthat theirop'e: maybe deflected, to permit the other section of thebushing to be withdravvn,-leavingy the bore 'clear for the withdrawal `ofthe sw'ivelmember 18. p

`From the'v `fore-going description, it will'be seen'l that I have Aprovided la: switch-rope socket in which Athe* swivel member' may be easily taken out througlithetop 'ofthe' soclret`or theipurposeof making a new end on andfyt, when the swivel isyinserted in the'socket and the 'bushii'iggproperly assemb`led,vlthe're"is no kchance orth'e socketv to becomey detached. kBy usingthissocket,
