ROPE-EYE ron WELL-Danis.

Specteation of Letters Patent.

Application :tiled Detener 1E, 1910. Serial No. 586,640.`

To alt 'l0/ioni it 'may concern.:

Bc it known that l, losiciii J. l-lisicxnos, citizeiiot' the United titlates, residing :it Sharon, in the county of Barber and State of Kansas, have invented certain new and useful improvements in Rope-Eyes for Well- I )rills7 of which the following is a*y specification. i

This invention relates to improvements in devices `for coupling the operating rope or vcable to a well drill and for like purposes,

and has'fcr one of its objects to improve the construction and iiiciease'the etliciency and utility of devices ot' this'character.

-.ftnotlierpbject of the invention is to" provide a device of' this character whereby the operating .cable or rope may be readily coupled yto and disconnected fioiiithe drill,

and without breaking or discarding any of the parts.

.Another object o't' the invention is to provide a simply constructed lockingir means hei-tween the cable coupling device and the drill rod.

`tiononthe line 2 2 pf Fig.' 1;'Fig. 3 is a transverse'section on the line 3-8 of Fig.'1,

looking in the direction of'the arrow. Fig. 4 is a transverse Vsection on`the line 1 1 ot'4 Corresponding and like parts are referred' toin the following description and indicated in all the views of the drawing by the saine reference characters. r

The improved device comprises a stock or head 1t) having an internally threaded socket 11 at one end to receive the threaded stud 12 of the drill bit 13. Formed within thestock 10 alongside of the threaded socket 1l is a cavity 14 to receive a bolt 15. the holt being arrangedv to enter sockets or ca\`iities in the adjacent face of the drill bit 13. Formed vthrough the side of the stock 1() opposite the recess 14 is a slot` 16, and a pin 17 is con-` ;.wied to the holt l5 and extends through the slot. to provide a convenient means 'for elevating the bolt and uncoupliiig it from the drill bit 13. A sprin 18, operates upt they pin or holt l5 and maintains the saine yieldably in its downwardposition and cou led to the drill bit 13. VBy this means the t rill hit is locked from retrograde movement after having been once turned Ahome By this means no danvfer exists of the accidental separation of the members 10--11 when iii` use.

opening 19, and likewise extending through the stock and communicating with the opening is a recess 20, 'while an upwardly directed cavity 21 is formed within the stock and extending upwardlyv from lthe opening 1,!) and communicating therewith. A vertical opening Q2 leads through the upper en'd of the stock and coniiiuii'iicates withthe recess 2l. as shown in Fig.' 2, the pull rope or cable Q3 Extendinglthrough the stock fo at, is upper end is a relatively large transverse passing downwardly through this opening.:

2Q, as hereafter explained.

A rope clamp forms an essential part of the improved device and is formed of two` plates 2st-25 having intermediate enlargements N3-@7 intermediate their ends to re ceive the rope or cable 33, the two parts Q-l--Q being unitedby transverse clamp bolts QS-). rl` he terminals StL-3l of the rope clamp are extended and fit, within the recesses E20, as shown. while the heads ot thc bolts enter the relatively large recess 2l and thus serve as stops to prevent the lateral displacement ot' the rope clamp. ljy this means all lateral movement' of the clamp is prevented and the ropev thereby protected from abrasion. By this simple means, the rope clamp is held from rotative movement, and

4thus firmly locked iii position' relative to' the stock 10, while at the same time readily removable when the table is to he disminiiected. The recess :21 provides ample room for tlie freeoperation ofthe cable. and cffectually prg-vents any danger of thecahle coiiiiiigir in contact witli the Stock.

The stock 10 is constructed of metal. preferably cast steel. may be ofauy required size to.adapt it to tliesize of .the drill hit with which it is employed, while the clamp members 24-425 are also formed of relatively heavy metah preferably steel. The relutivelv large opening 19 provides ample space ffoi the reception ofthe rope claJnp,

so ,that the latter may be readily released when desired. Femed in the side of the stoel: l0 is e longitudinal recess 3l opposite the slot 18, and slidebly engaged in thisv recess is :i cover member 3:2, which forms guard when in depressed position to the slot and the pin lo'eld therein. At its *upper end the slot 18 is provided with a. lateral -Oset' 33 into which the terminal 17 'of the pin `'.15 may be turned to hold the vpin in withdrawn position when the members 10M-13 are to be connected or disconnected. Having thus described the invention, what ...is claimed as new is:

yinner ends, n rope extending tln'ongli seid bore and into tliewpening, europe clamp within Said stock opening und comprising two plates for bearing upon opposite sides of the rope and extended at the ends ifoi engugingihe outer portions of said recesses, :1nd bolts nnilinff said clump plates :1nd including enlarged heads nt one end for en gagging/in the enlargements of the recesses und preventing lnternl-movement of vthe clninp plates and protect-ing the rope from aln'a'sien.
