T all ioiofm it may con/cern.'

Be it known that we, ALTON i?. YiA'roN and Lewis W. Bizni'iiooiin, citizens of the United States, and residents of Akron, county of Summit, State of Ohio, have invented certain new and useful Improvements in Rope Sockets, of which the following is a specification.

This invention relates to rope sockets used in well drilling apparatus. p

In the art of well drilling, the drilling tools are carried by a rope or cable passed up from a bull reel over a crown pulley on the top of a dei-rick or huist. The tools weigh up to three or four thousand pounds and the drilling is effected by raising the tools two to three feet by exerting a' pull on the cable and then allowing the tools to drop. 'taching the tools onto Vthe end of the rope or cable.

During the drilling operations the rope and particularly Wire cable transmits severe shocks and vstrains to the drilling apparatus. Accordingly, there has heretofore been einployed in the art, rope sockets in which cushioning means have `been employed to take up considerable of the shocks and .strains thus to prevent transmission thereof to the machine.

The chief object of the present invention is 'to provide an vimproved rope socket Wherei-n shocks and strains will 'be eiiiciently absorbed by cushioning means consisting of simple inexpensive and easily replaceable parts which will not be rapidly y(.leteriorated by the percussive action, the action of Water or the abrasive action of sand, gravel or the like. f i i y The above and other objects will become more apparent as the following description is read in connection with the accompanying drawings in which the preferred form of the invention is illust rated, it being understood that t'he invention is not limited to the particular form shown and described.

Of the accompany-ing drawings:

Figure 1 is an elevation of a rope socket embodying the invention; and

Figure 2 is a vertical diametral section therethrough. l c

Referring to the drawings, indicates, generally, die casing of a rope socket which is formed with a veroical bore 1.1

:its upper to provide :i an

Rope sockets are employed for at-` Seral No. 79.

A tube V11i is inserted through the reduced bore 12 in which it is freely slidable and is threaded at its lower end into -a block freely slidable and rotatable in bore 11. At its upper end thetube 14; extends out of bore 12 a sufficient distance to permitengagement therewith'by a wrench and it is flared outwardly at 1111L on its'upper end so as not to cut into -oi bind onto the rope or cable. yihe block 15 is formed witha vertical bore 16 communicating with the tube lll and enlarged at its lower end. Thedrilling rope or cable 17 passes through tube 14; and bere 16 and-the strands thereof are spread out at their lower ends and babbiltted -in the enlarged portion of bore 1G.

Between biock 15 and shoulder llandA encircling tube 1i in bore 11, the improved cushioning means of the invention are placed. 'lhese means include

annular cushioning elements

18, 18 of non-metallic yieldmg resilient or elastic material such as yrubbei' which is preferred over other resilient slidable ont-ube 14 are interposed between the rubber elements 18, the Washers being provided with annular lips or `shoulders 120, 20 extending pei'pendicularly from'the inner circumference thereof, the shoulder 2O on the lowermostivasher beingreceivedvin a circui'nferential groove 21 in lblock 15. The shoulders 2O define a space between the tube let and the elements 18 into which the rubs ber can How under compression and also lthe shoulders 2() serve to hold the elements 1Q in alignment to prevent their displacement' by shocks exerted thereon. The larger diameter of 4the elements 1S is such that space for the flow ofthe rubber under compression is provided between the elements 18 and the casing 10.` v

For holding the above-described parts in the bore 11 of easing 10, fa suit-able plu-g 22 'end thereof the Vthe casing and plug 23 on the block 15 so that as a blow is delivered to the tool, the greater portion ot the shock is absorbed by the elements 18 thus relieving the cable and drilling apparatus from severe strains. The tube lll protects the elements 18 from friction With the cable.

Modilications of the invention may be rcsorted to Without departing from the spirit thereof or the scope ofthe appended claims.
