Be it known that'I, JA Y R. Conisnrnfa citizen of the'United States, residing at New Wilson, in theicounty' of Carterand'State;

of Oklahoma, have" invented certain new and. useful Improvements in Spudding- Shoes, ofwhich the following isa pecificae f This invention relates to well drilling" im spudding shoes. 7

The object of the invention is toprovide an improved form of spudding shoe'whim; may be employed with all ropes and cables" which may be found in a well drillin outfit. In outfitting a drill rig, a well digger frequently finds it necessary to buy such hemp or Wire cables as are found in stock in supply houses where he may be operating, and in this manner he gathers a number of cables of different sizes and charac ter. Heretofore to the best of my knowledge, it has been necessary for a well digger to have on hand a spudding shoe capable of use with. each size cable which it might be necessary to bring into use, owing to the fact that spudding shoes each carry upon their outer faces a single groove which is cut to receive a particular size cable. It is therefore the intention of this invention to provide a spudding shoe which may be adapted for use with any sized cable by changing the grooved face of the shoe with an assorted number of faces which accompanies each shoe, so that the particular cable then in use may be accommodated.

With the above general object in view and such others relating to the details of invention as may hereinafter appear, my invention will now be fully set forth and described reference being had, to theaccompanying drawings, in which like reference characters indicate like parts throughout and Figure 1 is a fragmentary elevational View showing the manner of use of the spudding shoe. n

Fig. 2 is a vertical longitudinal section through the improved device.

Fig. 3 is a perspective view of one of the interchangeable faces.

Fig. 4 is a transverse sectional view.

L Sp t on of t s t Patented Aug.13, 1918;, A plicationfiledhpri is 191 s 'eriall l'o.229,30Cbj if i I i Fig. 5 a holding device;

Referring more particularly'to the draw' perspective view of i a rope.

ings, 1 represents'the body of the shoe which 7 may be of wood, metal or" other suitable material, said "body '1 being: generally arcu'ate' 1n form,'but upon ltSiI'Gi tI' or concave side ,601.

having" the bearing projection 2 within which is cutthe transverse bearing groove verse journal 4 01? a clevis'ory'oke' 5, said clevis 5 having the legs 6 which extend forwardly. across the sides of the body '1, and at their extremities are outturned into the hooks 7. The bearing 4; is held in place by means of a retaining plate 8 secured into position overthe bearing grooves 3, so as not to interfere with the ability of the clevis 5 to oscillate toward the ends of the body 1.

The hooks 7 formed on the ends of the legs 6 are open rearwardly, and are shaped to receive the trunnions 9 which extend beyond the sides of a rope holding block 10, the latter consisting of a wedge-shaped body having a groove extending longitudinally of its beveled faces and across the larger end of the block as at 11, so that a loop formcdin the end of a rope or cable may be engaged thereover; Aftersuch a loop has been engaged over the groove 11 -3. The bearing groove .3 receives thejtransthe trunnions .9 may be inserted into the 7 hOOKS 7 and it will be obvious that as long as tension is maintained upon the cable, which is indicated at 12 in Fig.1, the connection between the cable and the spudding shoe will be maintained, but as soon as the pocket into which the removable face 15 may be snugly seated, said face 15 consisting of an elongated arcuate plate whose rear face follows the curvature of the rear face of the convex body 1 and whose outer face is provided with a groove 16 dimensioned to receive thevparticular cable for which the plate is constructed. The extremities of the r face or plate 15 are provided with the rearwardly extending ends or lugs 16' which overlie the extremities of the body 1, and are drilled to receive the set screws 17, which enter the body 1 and firmly hold the face 15 in position for use. While only one of the faces has been indicated in the drawings they may be obviously furnished in any 1 number of sizes, which will accord with the requirements of the average well digging outfit, and when the shoe is to be used, it might be quickly arranged to operate upon the particular cable 13 which may be in use.

There is thereby avoided the necessity of changing the cable 13,, or carrying in the outfit a number of the spudding shoes which in themselves are more or less bulky and heavy. Furthermore, the nresenticonstruction permits the body 1 to be made of alighter and less durable material than is necessary, as in the present usage, when the.

shoes are constructed with integral faces.

Furthermore, by reason of the improved construction of the clevis and rapid attaching means the device is readily attached or removed from the rigging, with a. consequent saving of time to the user.

Vhat I claim as my invention, is

1. A spudding shoe including a body, and an arcuate removable bearing face carried I by the body.

2. A spudding shoe including a body, and V a' removable arcuate face carried byrthe extending forwardly therefrom and termi-v.

nating in open hooks and a rope holding element having trunnions engageable with said open hooks.

In testimony whereof I affix my signature.
