WELL-DRILLING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 748,517, dated December 29, 1903.

V Application led April 10, 1903. Serial No. 152,065. ('No model.)

:To all whom it 'may concern:

Beit known that we, FRANK R. MCKEE and EMMA E.MCKEE,citizens of the United States, residing at Coshocton,in the county of Coshocton and State of Ohio, have invented certain new and useful Improvements in Well-Drilling Machines, of which the following is a specification.

This invention provides a machine for sinking deep wells by the use of cable, drills, and spudding mechanism, the object being to facilitate handling and have the machine at all times under control.

The mechanism admits of the drill-rope at the beginning being jogged and at the latter stages of the operation being attached to the walking-beamo as to be reciprocated thereby. Clutches are dispensed with and brakeshoes arranged to hold the drums for the drill and bailing cables when it is required to prevent the rope paying off therefrom.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modication,still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a machine for drilling deep wells constructed in accordance with and embodying the vital features of the invention. Fig. 2 is a top plan view of the machine,the derrick and walking-beam being omitted. Fig. 3 is a side view showing the drums for the operating-cables and the mountings therefor on a larger scale. Fig. 4 is a view similar to Fig. 3, showing the bearings shifted. Fig. 5 is a front view of one of the drums, showing the eccentric bearing therefor. Fig. 6 is a detail view in elevation of the crank-wheel for imparting a jogging movement to the drill-cable. Figs. 7 and 8 are detail views of the crank-arm and jogging-wheel applied thereto. Fig. 9 is a detail view of a brake-shoe and the means for adjustng same to compensate for wear.

Corresponding and ,like parts are referred to in the following description and indicated in all the views ofthe drawings by the same reference characters.

The operating mechanism is shown mounted upon` a truck, so as to render the machine readily portable, the position of the machine being adapted` to be fixed in any manner. The bed 1 of the truck or machine maybe of any construction, according to the design of the machine and the special arrangement of the parts. A derrick 2 is fitted to the rear end of the frame and is strengthened by braces 3 and 4. This derrick may be of any height, according to the depth of well to be drilled, and is provided at its upper end with `sheave-pulleys 5 and 6, over which cables 7 and 8 pass. The derrickis adapted to be raised and lowered preferably by means of the mechanism mounted upon the frame. The walking-beam 9 is fulcrumed intermediate of its ends to Samson-post 10, rising from the rear end of the machine and stayed by braces 11. The inner end of walking-beam `9 has pitman'12 pivoted thereto,and the outer end is provided with the usual grip (not shown) `for receiving the drill-cable when spudding, connection 13 suspending the gripl convenient point by means of-rod 21, said rod being adapted to be secured so as to hold pulley 16 in the desired position. A shaft 22 is journaled parallel toshaft 14 and is provided with Vdrum 23 and friction-pulley 24 and is mounted at one end in eccentric bearing 25, from which lever 26 projects, and is connected to operating-rod 27, extended within convenient reach and adapted to be secured so as to hold pulley 24 in the desired position. Brake-shoe 28 is located in Vthe rear of pulley 24, and the latter is adapted to be thrown into contact witheither pulley 19 or brake-shoe 28, according as drum 23'is to be positively driven or held fixed. Cable 8 is adapted to wind upon drum 15 and carries IOO sand-bucket 29 for hailing the Well. Cable 7 is adapted to wind upon drum 23 and is adapted to have the drilling-tools connected thereto. The drill-cable is either jogged or .has a vertical reciprocating movementimparted thereto, as may be desired. i Driveshaft 30 is located intermediate of shafts 14 and 22 and is provided at one end with drivepulley 19 and at its opposite end with bandpulley 3l, to which motion is imparted when the machine is in operation from any source of power, said shaft 30 being continuously driven. j

Shaft 32 is located near the rear end of the machine and is provided with band-pulley 33 and is connected by drive-belt 34 with bandpulley 35 of shaft 30. Crank-arm 36 is secured to shaft 32 and is provided with a series of openings 37 to receive wrist-pin 38 in any selected position, whereby the stroke of the drilling-tool may be regulated according to the distance of wrist-pin 38 from the axis of shaft. 32. The wrist-pin 38 may receive the lower end of pitman 12 when walkingbeam 9 is to be operated or may be provided with wheel 39 for imparting a jogging movement to the drill-cable when the tool is to be operated by a jogging motion of the cable. The jogging-wheel 39 is grooved in its periphery, so as to receive drill-cable 7 andv prevent displacement thereof. A direction-pulley 40 is located in longitudinal alinement with jogging-wheel 39, so as to prevent lateral displacement of the drill-cable therefrom when the machine is in operation.

The engine (not shown) maybe of any make, such as commonly used for drilling operations, and may be mounted upon the same' frame with the drilling mechanism or be independent therefrom, so as to be used in other connections, this feature of construction being unimportant. The shaft 30 being continuously driven, motion may be taken therefrom for operating drums 15 and 2 3 by operating- rods 21 and 27 to throw pulleys 16 and 24 into contact with drive-pulley 19, thereby winding the cable on the respective drum, so j as to lift either the tool or the sand-bucket. The drums are held stationary by throwing the pulleys into contact with the coperating brake-shoes. When the pulleys 16 and 24 occupy a position intermediate of drive-pulley 19 and their brake-shoes, the cables may pay off or unwind therefrom to lower either the drilling-tool orthe hailing-bucket. DuringV the first stages vof drilling the well it is preferred to operate the drill by jogging the oable,vthis operation vbeing effected by disconnecting pit-man 12 from crank 36 and applying wheel 39 to said crank and passing the drill-cable 7 beneath said wheel, as indicated in Figs. 1 and 6. When the well has reached ak comparatively great depth, the joggingwheel 39 is removed and pitman 12 connected to crank 36, the drill-rope being connected to vthe part 13 at the outer end of walking-beam `9 in any convenient way. The drill-rope is run o from drum 23 as the work progresses by throwing pulley 24 away from brake- 'shoe 28.. Y

The brake-shoes are pivoted at their lower ends to the frame of the machine, as shown at 41, and have adjustable connection at their upper ends to braces 42, whereby provision is had for taking up Wear.

Having thus described the invention, what is claimed as new is In well-drilling machinery, the combination of a drive-pulley, a drum for receiving the drill-cable, a brake-shoe, a pulley connected lwith said drum and adapted to be thrown into icontact with either said drive-pulley or the v'brake-shoe or to an intermediate position, a shaft 32 connected with and receiving motion Efrom the shaft carrying the aforementioned ,drive-pulley, a crank attached to the inner 'endof the shaft 32, a pulley having adjustable connection with the said crank and .adapted to operate the drill-cable and the tool :attached thereto, and a pulley applied to the iframe in line with the pulley carried by the said crank to hold the drill-cable in line there- `with, substantially as specified.

In testimony whereof We affix our signatures in presence of two witnesses.
