ROCK-DRILL EXTRACTOR.

r Specification of Letters Patent. Patented J uly 19, .1910.

Application filed June 22, 1909. Serial'No. 503,662.

To all whom it may concern:

Be it knownthat I, WILLIAM EDGAR WEEKES, citizen-ofthe United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented new and useful Improvements in Rock-Drill Extractors, of which the following is a speci fication. v

This invention relates to grappling tools and has for its object to provide a. device of this character which consists essentially in the employment of a pair of, spring jaws, shaped in such a way that they can be introduced around the drill bit or a broken portion thereof, combined with novel means for effecting the openingand closing movements of the jaws to effectively grip and release a bit.

With these and other objects in view, as will appear as the description proceeds, the invention comprises the'various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claim appended hereto.

In v the accompanying drawings, which illustrate one embodiment of the invention, Figure 1 is an elevation of my improved grappling tool. Fig. 2 is a vertical longitudinal section of the same. F ig. 3 is a detail perspective view of the gripping jaws of the tool, and, Fig. 4 is a detail perspective view of the bifurcated end portion of the casing.

In the accompanying drawings the reference character 1 designates a tubular casing externally threadedat one end for engagement with a nut 2, which is provided with an opening 3, and said nut adapted to close the end of the casing 1; while the other end of the casing 1 is bifurcated as shown at 4. The arms of the bifurcation are semi-circular in section as'indioated at 5 and are flared putwardly, the purpose of which will appear ater.

Mounted within the casing 1 is ar rod or bar 6 which is rovided with centering collars T to hold t e saidbar 6 centered in the casing so as to facilitate easy and free longitudinal movement of the said rod. One end of the rod 6 is provided with screw threads for engagement with the nut 8 of the crank handle 9. An expansible spring 10 is mounted upon the rod 6 bearing against the inner face of the nut 2, and one of the spring clamping jaws 12 which are semicircular in cross section. 5

In order to effectively remove'a broken bit or the like from a hole, the jaws of the grappling tool are opened by unscrewing the crank handle 9 which allows the spring 10 carried by the rod to move said rodin a direction to permit the spring jaws to expand. Having inserted the tool in a hole and the spring clamping jaws introduced around the article to be removed, the crank handle 9 is screwed up which draws the rod 6 rearwardly compressing the spring 10 and inward movement against the flared arms of the bifurcated end 4 of the casing.

It will be obvious from the foregoing description that a grappling tool of this character can be employed to effectively remove bits and portions thereof or the like from holes drilled thereby and thus obviate the difficulties now encountered in the removal lengthandhaving the opposite sides of said recess inclined outwardly, a cap arranged on the opposite end of the casing and having an opening in axial alinement with the easing, a rod of greater length than the casing slidably fitted therein and provided with spaced centering collars bearing on the inner surface of the casing, that end of the rod extending through the recessed end of the casing terminating in a pair of resilient and outwardly inclined gripping jaws, the opposite end of said rod being screw-threaded and extending through the opening of the cap, a helical compression spring encircling the rod and liavin its opposite terminals bearing on one o the collars and cap and operating to project the said jaws through the recessed end of the casing, and a crank handle screwed onto the threaded end of the rod serving to retract the jaws through the recessed end of the casing.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM EDGAR WEEKES. Witnesses:

LUTHER M. ALLEN, WM. P. APPLELY;

forcing the spring arms together by their of said articles. 1

What is claimed as new is v ,A grappling tool comprising a casin recessed at one end in the direction -0 its centering collars 7. The rod6 at the o poi site end is bifurcated as shown at 11 to orm
