WELL-DRILLING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 732,206, dated June 30, 1903. Application filed February 5, 1903. Serial No. 141,966. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL B. MARTIN, a citizen of the United States, residing at Rittman, in the county of Wayne and State of Ohio, have invented a new and useful Improvement in Well-Drilling Machines, of which the following is a specification.

My invention relates to well-drilling ma chines adapted particularly for operation by steam or analogous power; and the object in View is to provide a generally-improved device of this class which will be exceedingly simple in construction, inexpensive of manufacture, and efficient in use and which will be better adapted to its intended purposes than any other device of the same class now in use.

This invention relates to improvements in drilling-machines for either deep or shallow wells; and it has for its paramount object the provision of a simpler and more efficient means of reversing the motion of the machine and the consequent raising and lowering of the rope and tools withoutreversing the engine.

The machine may be run with astationary engine attached to the rear of the frame of the machine, or it may be driven by an independent portable engine.

In drilling-machines heretofore in use the device known as a spudder worked on the top of the drill-rope, while in this machine it works from beneath the rope, lifting or throw ing the rope outwardly and upwardly, which is believed to give a better stroke for drilling purposes.

In drilling-machines which employ a walking-beam and also in many other machines the machine has to be stopped atintervals of eight or ten feet for the purpose of letting out rope, while in this machine the rope is let out as needed, and continuous drilling is allowed.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims, it being understood that the improvement is susceptible of various changes in the form, proportion, size, and the minor details of construction without departing from the principles or sacrificing any of the advantages of this invention.

Referring now to the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of a drilling-machine constructed in accordance with this invention in its operative position. Fig. 2 is a horizontal sectional view of the same, taken on line a b of Fig. 1. Fig. 3 is a detail View of the mechanism for reversing motion. Fig. i is a perspective view of the walking-beam arms and the pitman-arm of the machine. Fig. 5 is an enlarged sectional View of the main driving-pulley 16 with reversing mechanism. Fig. 6 is a plan view of a portion of the tower arms or beams forming the derrick or ladder of the machine.

Similar characters of reference indicate like parts throughout all the figures of the drawings.

It will be seen that the machine is provided with the ordinary base-frame 1, mounted, if desired, on wheels, as shown, and provided at its front end with two upright tower arms or beams 2, forming a derrick or ladder, at the upper end of which there is mounted a crownpulley 3, over which the rope 4 passes. The upright arms or beams 2 arejointed, as at a, by means of bolts 5, so that the same may be taken down and folded back rearwardly over the machine, if desired, in transportation, (K50.

At the rear of the machine there is provided two upright arms or beams 6, from which there extends two brace arms or beams 7, fastened to the upright tower arms or beams 2 for the purpose of securely holding the same in upright position. Mounted in the upright arms 6 is the shaft 8, provided with pulleys 9, one of which receives motion from the engine by means of a belting 10 and the other of which transmits motion to a lower pulley 11 by means of a belting 12. The pulley 11 is secured to the end of a shaft 13, suitably mounted on the frame 1, and at the other end of the shaft l3 there is mounted another pulley 14, over which passes a belting 15, passing over and transmitting motion to the main driving-pulley 16, hereinafter more fully described. The main driving pulley 16 is mounted on the end of a shaft 17, mounted in suitable bearings secured to the base-frame 1 and which shaft 17 is provided with a 7 crank-arm 18, to which is secured the lower end of a pitman-arm 19, attached at its upper end, which is forked into two arms 19", to two arms 20, at the ends of which there is mounted the spudder-pulley 21, which always rests against the lower side of the rope 4. The rear ends of the arms 20 are pivotally attached, as at b, to the upright arms 6, heretofore referred to. It will thus be seen that when the machine is running in the direction of the arrows the spudder-arms 20, carrying the spudder-pulley 21, will be moved to and fro, upwardly and rearwardly, throwing the rope 4 in the same direction and imparting a drilling motion to the rope 4 and tools attached thereto.

Referring now to the main driving-pulley 16, it will be seen that it is provided with an annular groove or recess 23 near its periphery, providing on its inner and outer sides 24 and 25 a friction bearing-surface.

26 designates a shaft suitably mounted on the frame 1, having on one of its ends a friction-pulley 27, (see Fig. 3 and Fig. 5,) which takes into the groove or recess 23 of the main driving-pulley 16, and having on its other end a friction-pulley 28 and a gear-wheel 29, meshing with a larger gear-wheel 30, mounted on a shaft 31, mounted in suitable bearings attached to the frame 1 of the machine, and which shaft 31 forms a spool for winding the rope 4 upon. The end-of the shaft 26, adjacent to the main drive-pulley16, is mounted in a longitudinal groove or recess formed in the bearing-block d, and the friction-pulley 27 is moved to and fro against the inner and outer sides 24 and 25 of the annular recess 23 of the driving-pulley 16 by means of a lever 32, pivotally attached, as at c, to the side of the frame of the machine and having one end provided with a bearing 33 for the shaft 26 and at the other or lower end provided with a rod 34, attached to an operating-lever 35,'suitably mounted near one end of one of the base frames or beams of the machine, as shown.

It will be seen that when the driving-pulley 16 is running in the direction of the varrow and the operating-lever 35 is moved so as to bring the friction-pulley 27 in contact with the inner side 24 of the annular recess 23' the gear-wheels 29 and 30, with their shafts, will be moved in the direction indicated by the arrows, and the rope 4, with attached tools, will be wound up; but when the operatinglever 35 is moved in the opposite direction, so as to bring the friction-pulley 27 in contact with the outer side 25 of the annular recess 23, the gear-wheels 29 and 30, with their shafts, will-be moved in theopposite direction, letting rope 4 and attached tools down.

It will be understood that when it is desired to raise or lower rope and tools the pitman-arm 19 will be detached from crank-arm 18 of shaft 17 and pitman-arm 19 hung over ing the friction-pulley 28 may be slightly re-.

leased and allowed to slip slightly, thus allowing the rope 4 to'be gradually paid out.

39 designates a loose or floating pulleymounted in a supporting-arm 40, pivotally attached at its lower end, as at e, to one side of the base-frame 1.

.41 designates a rod attached to the supporting-arm 40 and running to the front end of the machine and terminating in a handle 42, by means of which the belting 12 may be loosened or tightened,

When it is desired to keep the engine running and yet stop or not run the other mechanism of the machine, the belting 12 is loosened by means of the floating pulley 39, thus permitting the belting 12 to run and pass loosely around the pulley 11 without transmitting any motion to the same.

It will be understood that when drilling the operating-lever 35 will be moved to such a position as to bring the friction-pulley 27 within the center of the annular recess 23 and out of contact with the inner and outer sides 24 and 25 of the same, thus moving the spudder only through the pitman-arm 19, attached to the crank-arm 18 of shaft 17, to which the driving-wheel 16 is attached.

If desired, a sand-reel shaft with reversing mechanism like that hereinbefore described may be mounted like shaft 31 on the forward ends of the base-frame 1 and arranged to have its end provided with a friction-pulley take into the annular groove or recess 23 of the driving pulley 16 near the front portion thereof.

From the foregoing description, taken in connection with the accompanying drawings, the operation and advantages of myinvention will be readily understood by those skilled in the art to which it appertains.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is a 1.
