0. s. WRIGHT SPUDDING SHOE Oct. 20, 193.1.

Filed NOV. 13. 1929 INYENTOR Patented Oct. 20, 1931 verso sTA'rE s PATENT OFFICE CLYDE S. WRIGHT, OF TOLEDO, OHIO, ASSIGNOR TO THE NATIONAL SUPPLY OOIVIPAN Y, OF TOLEDO, OHIO, A CORPORATION OF OHIO SPUDDING SHOE Application fil-ed November 13, 1929. Serial No. 406,948.

My invention relates to spudding shoes which are well known devices used preliminarily in the operation of drilling a well.

Well drillers find more or less difliculty, es-

gj pecially when spudding rapidly, in keeping the drilling cable in operative connection with the spudding shoe due to the severe whipping or erratic swaying and jumping of the shoe, particularly whenever the drilling 10 cable is fed out faster than the drilling tool progresses downwardly. It is the principal object of this invention to provide spudding shoes with safety features to prevent the drilling cables from getting out of their normal working positions in the shoes.

Referring to the accompanying drawings, Fig. 1 is a side elevation of the spudding shoe with portions of a drilling cable and a jerkline therefor; Fig. 2, an enlarged side view of the shoe; Fig. 3, an end elevation of the shoe; and Fig. 4, a section on the line 4-4 on Fig. 2.

1 designates the body of the spudding shoe. The body has an arcuate groove or cable bearing 2 in one edge to receive the drilling cable 3, only a portion of which is shown. The groove may be in an integral portion of the body, but I prefer to have it in a liner 4 seated in the arcuate passage 5 in the shoe, the liner being held in the passage 5 by the bolts 6.

An arm 7 projects outwardly from the arcuate side 8 of the body and preferably at right angles thereto. It has at its free end the fork 9 between whose members the roller 10 is mounted on the bolt 11 which acts as a pivot for the roller. 12 is a jerk-line of the ordinary kind having the eye 13 in which the roller 10 is positioned.

The arm 7 has its origin preferably midway between the ends of the body, the parts being arranged so that preferably the drill cable in the groove 2 and the eye 13 include the same plane.

Between the fork 9 and the adjacent side 8 of the body 1 is the abutment, rib, or fin 14 which is separated from the side 8 by the space 15 which is wide enough to permit the passage of the cable 3 into the groove 2. The abutment rises from the face 16 of the arm 7 and lies at one side of the groove 2 and extends above the face 16 sufficiently far to assist in holding the cable in its normal place in. the groove 2.

There are two hooks 17, one between each end of the body 1 and its central portion. The hooks rise from that part of the body which is opposite the arm 7 or the face 16 and extend out beyond the side 8 of the body, the free ends being turned toward the plane including the face 16 so as to over-lie the groove 2 and the part of the drilling cable 3 therein and prevent the latter from jumping out of the groove.

The cable 3 is prevented from escape from the groove by means of the abutment 14 and the hooks 17, the abutment being carried by the shoe at one side thereof and the hooks being carried by the shoe at the other side thereof. This abutment 14 need not be a narrow rib or fin as shown, it only being nec essary to have a space 15 whose length depends on the predetermined thickness of the abutment 14.

The shoe has on one side a strengthening rib 18 and on the opposite side the rib 14 and the rib 19, the latter being on the same side of the shoe as the rib 14 and alined therewith. The opposing ends of the

ribs

14 and 19 are rounded to aid in guiding the cable to the space 15.

I claim:

1. A spudding shoe having a cable bearing and rigid hooks overlying the bearing at each side of the center thereof.

2. A spudding shoe having a cable bearing and rigid hooks overlying the bearing at each side of the center thereof, and an abutment lying opposite the bearing and between the hooks.

3. A spudding shoe having a cable bearing in one edge, an arm projecting beyond the said edge and adapted for connection to a jerk-line, an abutment positioned on the arm in front of the bearing and spaced therefrom to provide for the entry of a drill cable to the bearing and means overlying the arm and spaced therefrom and from the abutment to confine the cable in the space enclosed by the bearing, the abutment, the arm and the said means and to provide an ever-open path for passing the cable laterally into and out of the said s ace.

4. spudding shoe having a cable bear- 5 ing in one edge, an arm projecting beyond the said edge and mrhzted for connection to a jerk-line, and fixed eoks carried by the body at the sides of the abutment and overlying I the bearing. i In testimony whereof, I hereunto afl'lx my signature.

CLYDE S. WRIGHT.
