WELL-DRILLING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 736,716, dated August 18, 1903.

Application filed February 24, 1903. Serial No. 144,636. (No model.)

To (tZZ whom it may concern:

Be it known that I, Gnonon A. GILBORNE, of Aberdeen, county of Brown, State of South Dakota, have invented certain new and useful Improvements in VVell-Drilling Machinery, of which the following is a specification.

My invention relates to machinery designed for use in drilling wells; and the object of the invention is to provide a compact portable apparatus that can be readily transported from place to place and conveniently set up and put in operation within a short space of time after being located where the work is to be done.

A further object is to provide an apparatus that is simple in construction and easily operated even by an inexperienced person.

A further object is to provide a machine that is self-contained, all operating parts and power-generating means being included within the single structure, and hence more conveniently handled than other machines usually used for the same purpose.

The invention consists generally in various constructions and combinations, all as hereinafter described, and particularlypointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan view of a well-drilling machine embodying my invention, the upper portion of the apparatus being cutaway, the supporting-timbers therefor being shown in section. Fig. 2 is a side elevation. Fig. 3 is a plan View. Fig. 4 is a detail of a belt-tightening mechanism. Fig. 5 is a detail, partially in section, of the device forimparting reciprocating movement to the drill and the reciprocating device over which the rope passes to the drill. Fig. 6 is a detail of the worm-wheel and rod in mesh therewith. Figs. 7 and 8 are side and sectional views, respectively, of the disk shown in Fig. 5; and Fig. 9 is a detail showing an adjustable pump-rod connection by means of which the pump may be rendered operative or inoperative, as desired.

In the drawings, 2 represents parallel side timbers, supported on the wheeled axles 3 and 4: and connected at intervals by the cross timbers or bars 5. At the rear end of the frame are the upright inwardly-inclined timbers 6, that form the lower section of the drill-machine tower. These timbers are connected by the cross-slats 7 to the upper ends of said timbers. A folding section 8 is hinged on a rod 8. Bars 9 and 10 pivotally connect the middle portions of the timbers 7 and the folded section 8. A pulley 11 is provided on the rod 8, and a similar pulley 12 is provided at the outer end of the section 8. When not in use, the folding section is swung down against the timbers 6, Where it is suspended in a compact folded position until the machine has been located near the work. It is then raised, as hereinafter described, to the position shown in dotted lines in Fig. 2, and suitable guy-ropes (not shown) are provided for staying and supporting the tower in its upright position.

Near the middle of the machine I arrange a framework consisting of the posts or standards 13, resting upon the side timbers 2 and the intermediate timbers 14, and upon this framework I arrange a shaft 15, provided with a drum 16 and a worm gear-wheel17. A rope 18 is wound upon said drum and passes under a pulley 19, mounted in a forked bar 20, and from thence passes over the pulley 11 and is connected to the bars 9 at a point near their pivotal connection with the bars 10. (See Fig. 2.) The bar 20 is secured at its lower end to an arm 21, and at its upper end is connected to guide-bars 22, that are pivoted to the timbers 13 and support the said bar 20 in an upright position, while permitting its vertical movement. The arm 21 is mounted on a pin 23, carried by a crank 24 on ashaft 25, that is mounted in hearings in the timbers 2 and 14. This shaft has a longitudinal movement in its bearings, being operated by means of a pivoted lever 25, engaging a grooved collar 26, secured on said shaft. A projecting end 27 is provided on a pin 23, that is adapted to enter a slot 28, provided in a disk 29 on a shaft 30, that is also mounted in bearings in-the timbers 2 and 14 on the opposite side of the machine from the shaft 25. A block 30 is pivoted within the slot 28 and is normally held therein by a spring 31. Operation of the lever 25" will move the shaft 25 lengthwise and advance the pin 27 into the slot 28 against the block 30 and the tension of its spring. The operator will thus be able, when the disk 29 is revolving, to thrust the pin 27 into the slot and cause the operation of the bar 20 without stopping the machine. An elliptical gear 32 is provided on the shaft 30, meshing with a similar gear 33 on a shaft 34, and through the operation of these gears the disk 29 will be operated at a varying speed. A large gear 35 is provided on the shaft 34, meshing with a pinion 36 on a shaft 37. Apulley 38 is connected by a belt 39 with a similar pulley on a shaft 40, provided with fly-wheels 41, and said shaft 40 is connected with the piston of an engine 42, mounted on the frame of the machine at its forward end, and being of ordinary construction is not shown or described in detail herein. The shaft 37 is preferably provided with a fly-wheel 43. The opposite end of the shaft 34 from the gear 35 is provided with a sprocket 44, connected to a similar sprocket on a shaft by belt 46. The shaft 45 is provided with a pulley 47, connected by a belt 48 with a pulley 49 on the shaft 15. This belt 48 is sufficiently loose on the pulleys to allow movement of the shaft 45 without operating the shaft 15; but said shaft 15 may be operated from said belt by movement of the belttightener 50, that is operated by means of the long arm 51, connected with the pivoted lever 52. The shaft 45 is provided at one end with a disk 53, whereon a hollow rod 54 is eccentrically mounted, and a stem 55 fits within said rod and is adjustably secured therein by means of a set-screw 56. The outer end of said stem is pivotally connected with the piston-rod 57 of a pump 58, which is of ordinary construction, and not being claimed herein requires no detail illustration. The pump may be rendered inoperative at any time by loosening the set-screw 56 and allowing the stem' to slide therein without operating the piston. I prefer to provide a friction-brake device on the shaft 15, consisting 'of a pulley 59 and a strap 60, secured at one end to the standard 13 and at its other to the pivoted lever 61, whose free end normally rests on a pin 62. Whenever desired, the operator can raise this lever off the pin and bearing down on the same cause the strap 60 to grip the surface of the pulley and stop the revolution of the shaft 15 and the ropedrum.

Beneath the worm gear-wheel 17 I provide a rod 63, having an operating-wheel 64 anda worm-gear 65, adapted to engage the teeth of the worm-wheel, and said rod is slidable in a bearing 66 to allow said gear to be moved into and out of engagement with the teeth of the worm-wheel, as indicated by full and dotted lines in Fig. 6.

The following is a brief description of the operation of my improved well-drilling machine: The apparatus having been set in the desired position where the work is to be performed, the tower is raised by unfolding the hinged sections. The rope is then disconnected from the bars 9 and passed over the pulley 12 and connected to the drill, as indicated by lease the belt and allow the shaft 34 to reciprocate the bar 20 without operating the shaft 15. This reciprocation of said bar will raise and lower the drill in the usual manner. As the hole is drilled deeper and more rope is required the drum is unlocked and revolved a few times until the desired amount of rope is obtained, when it is again secured and the operation of drilling again continued. Whenever it is desired to discontin ue entirely the operation of drilling, the dru m-shaft will be revolved in the opposite direction, revolving the worm-wheel in the direction indicated by the arrow in Fig. 6 and automatically throwing the worm 65 out of engagement with the teeth of the worm-wheel. The well having been completed, the operator will disconnect the rope from the drill, lower the upper section of the tower to its folded position, when the machine is ready to be moved to another piece of work.

I claim as my invention- 1. The combination, with a wheeled frame, and the tower provided thereon, of a ropedrum and shaft mounted on said frame, means for operating said shaft, a shaft 30 connected with said operating means, a disk 29 secured on said shaft 30 and having a slot 28, a block 30 yieldingly held within said slot, a longitudinally-movable shaft 25, a crank 24 carried thereby, a pin 27 carried by said crank and arranged to enter said slot, a bar 20 carried by said crank and provided with a pulley over which the rope passes from said drum.
