THOMAS A. WILLIAMS, OFELKINS, nnwivrnxico.

wnnrmarnn 1.25 was.

To all whom it may concern:

Be it known that I, THOMAS A. VVILLIAMs, a citizen of the United States, residing at Elkins, in the county of Chaves, State of New Mexico, have invented certain new and useful Improvements in VVell-Drills; and I dohereby declare the following to be a full, clear, and exact description of the in- :vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a well drill.

An object of the invention resides in the provision of a generally improved structure of a machine of this class so that it will be simple to manufacture and easily operated. V

A further object of the invention resides in so constructing the machine that it may be conveniently used for spudding in or cutting initially into the ground or for drilling deeply into the ground. 7

With these and other objects in view, such as will appear as my description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claim.

In the drawing:

Figure 1 is a side elevation of a machine constructed in accordance with my invention showing the parts in the positions they will occupy when the operation of spudding in or initially "cutting the ground is in progress:

Fig. 2 is a similar view showing the parts in the positions they will occupy during the deep drilling operation;

Fig. 3 is a fragmental elevational view showing the positions of the parts when the fly wheel is inoperative to raise the drill;

Fig. 4' is an elevational view looking at right angles to Figs. 1, 2 and 3;

Fig. 5 is a sectional view on line 55 of Fig. 2, and

Fig. 6 is a sectional view on line 6-6 of Fig. 2.

The embodiment of the invention illustrated in the drawing includes 'a frame 1 from which a tower 2 extends which is braced by suitable supports 3. A suitable fly wheel 4 is mounted on the frame 1 in bearings 5 and pivotally mounted at '6 on the frame 1 is a rocker member 7 which includes a pair of spaced side bars 8 which are secured togetherat th ir upper'ends by Specification of LettersPatent. ]Pa fi ng]mtqgfl Well 25, 191$ Application filed August 16, 1916.

extending rod 10. A locking member 11 is pivoted tothe frame 1 at 6 independently of the rocker member and is connected to the fly wheel 4 by a pitman 12. This look ing member 11 is adapted to swing between the bars 8 of the rocker member and to be secured in such position by a keeper 13 which is pivoted at 14 to the bars 8 and is normally drawn downwardly by a spring 15 so that it will engage over the upper end of the locking member 11. This upperend is provided with a camface l6 which when the locking member is swung between the bars 8 of the rocker member 7 will force the keeper 13 upwardly against the tension of the spring 15 and permit the keeper to drop in place over the end of the said look ing member 11. This keeper may be lifted from its position on the locking member 11 by means of a suitable cable 17 which is secured to the keeper and extends over

pulleys

18, 19 and 20 and is connected to a controlling lever 21 within easy reach of the operator Thus it will be seen that when the rocker member 7 is locked to the pitman 12 by means of a locking member 11 and the fly wheel 4 rotates, the said rocker member will be oscillated on its pivot 6.

When the machine is used for drilling deeply the parts will be in the positions shown in Fig. 2 of the drawing. At this time a pair oi cables 22 is secured, detachably, to the upper ends of the bars 8 of the rocker member 7. These cables pass over a pair of pulleys 23 whichare carried by the tower 2 and are secured to a temperscrew 24 through the medium of a cross-head 28. When the fly wheel rotates the rocker memher 7 will be oscillated on its pivot and the temper screw raised and lowered.

When the machine is used for spudding in or initially cutting the ground the cables 22 are removed from the rocker member and a drill line is arranged in the-manner illustrated in Fig. 1 of the drawing. This drill line is windable upon a drum 25 which is actuated by any suitable means and passes upwardly overa pulley 26 and thence around a pulley 27 at the upper end of thetower and is attached to the drill. The pulley 26 is carried by a pair of bars 28 which are slidably mounted on a rectangular rod 29 which rod extends between the upper ends of the side bars 8 of the rocker member 7. The pulley may thus have lateral movement in order that the cable may be wound evenly f tower and is connected to the slush bucket (not shown) lVhen the locking member ll'is disconnected from the rocker member 7 the motion of the flywheel at will be ineffective to oscillate the rocker member and consequently, irrespective of whether the operationis that 0f spud ding in or drilling deeply, the

drill will not'be actuated.

- While I have illustrated and described a particular embodiment of my invention it 7 haS merely been for the sake of convenience and I do not wish to be limitedtothat parr ticular embodiment as it is obvious that numerous changes may be made in the details of con'st-ruction without dep'art-i'ng from we of this atent m be umai'nea xor the spirit of the invention or exceeding the scope of the claim.

What I claim is In a well drill, the combination of a frame, a rocker member pivoted to the frame and extending upwardly therefrom and ineluding a pair of spaced bars, a locking member pivoted to said frame and adapted to swing between the bars of said rocker member and having a cam at its upper end, a keeper pivoted between said bars and adapted to engage over said cam and retain the locking member in cooperative relation with said rocker member, a spring connected to said keeper and to one of said bars for normally retaining the keeper in operative position, a fly wheel, a pitman connecting the locking member and fly wheel, and a cable extending from the upper end of the rocker member.

In testimony whereof, I aflix my signature, in the presence of a witness.

THOMAS A. WILLIAMS.
