WELL-DRILLING MACHINE.

To all whom it may concern Be it known that I, FREDERICK A. HEBER- LING, a citizen of the United States, residing at Centralia, in the county of Marion and State of Illinois, have invented certain new and useful Improvements in Vell- Drilling Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in well drilling machines.

One object of the invention is to provide a well drilling machine having an improved construction and arrangement of spudding mechanism.

Another object is to provide an improved construction and arrangement of driving mechanism for the winding drum of the tool operating cable and means whereby said driving mechanism is quickly thrown into and out of gear.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and particularly pointed out in the claims.

In the accompanying drawings: Figure 1 is a side view of a well drilling machine showing the application of my invention; Fig. 2 is a top plan view thereof; Fig. 3 is a vertical longitudinal section showing the construction and arrangement of the spudding mechanism; Fig. '-1 is a detail sectional view of the spudding cam and means whereby the spudding cable is connected thereto; Fig. 5 is a side view of the parts shown in Fig. 4; Fig. 6 is a detail sectional view through one side of the frame on the line 6-6 of Fig. 1 showing the manner in which the sliding bearing box of the tool operating shaft is secured to the frame of the machine.

Referring more particularly to the drawings, 1 denotes the frame or body of the machine which is provided at its rear end withsupporting wheels 2 and at its front end with supporting and steering wheels 3. Arranged on the frame or body 1 preferably at the rear end and adjacent toone side thereof is a horizontal engine 4. On the crank shaft of the engine is mounted a drive pulley 5 which is connected by a Specification of Letters Patent.

Application filed July 13, 1911.

Patented May 14., 1912. Serial No. 638,345.

main drive belt 6 to a large main drive pulley 7 fixed on the outer end of a drive shaft 8 journaled in suitable hearings on the frame near its forward end as shown. On the opposite end of the drive shaft 8 from the wheel 7 is fixedly mounted a crank arm 9 having arranged therein an adjustable crank pin 10 which is pivotally connected the lower end of a pitman rod 11 the upper end of which is connected with one end of a walking beam 12 which is pivotally mounted on suitable supporting bars 13 arranged on and projecting upwardly from the frame adjacent to one side of the same as shown. To the outer or free end of the walking beam is secured the usual or any suitable cable engaging mechanism 14 whereby the tool operating cable may be readily connected wit-h and disconnected from the walking beam.

Arranged at a suitable position on the frame of the machine is a cable winding drum 15 on which is adapted to be wound a tool operating cable 16. The shaft 17 of the drum 15 is loosely mounted at one end in a bearing 18 secured to one side of the frame and at its opposite end is loosely mounted in a bearing 19 which is slidably secured to the opposite side of the machine by clips 20 which are bolted to the adjacent side beam of the frame and have their upper portions projecting a slight distance above said beams to form guide loops with which are engaged oppositely projecting lugs 21 formed on the lower portion of the bearing 19 whereby the latter may be shifted on the side beam of the frame. On the shaft 17 of the drum 15 is fixedly mounted a friction drive gear 22. The gear 22 is preferably provided with a V-shaped periphery which when the shaft 17 is shifted in the proper direction is adapted to be brought into frictional engagement with the similarly shaped periphery of a friction drive gear 23 fixed on the main drive shaft 8 whereby the motion of said shaft is imparted to the shaft 17 and the latter and the winding drum 1;) thus driven in the proper direction. The bearing 19 of the shaft 17 is shifted to bring the gear 22 on said shaft into engagement with the gear 23 on the drive shaft by means of a shifting mechanism comprising a shifting lever 24L which is connected by a link 25 to a lug 26 on the adjacent bearing of the drive shaft 8 onto some other fixed point. The lever 24 is also connected at its lowerend or below the link to the bearing 19 of the shaft 17 bymeans of a link 27 whereby when sald lever is swung in one direction or the other the bearing 19 and the shaft 17 W1ll be shifted to bring the friction gear 22 mto and out of operative engagement with the friction gear 23 on the main drive shaft thus providing for .the operation of the drum 15 for winding the cable 16 or permitting the same to unwind therefrom. The lever 24 is preferably connected by an operating rod 28 to a hand lever 29 arranged on the rear end of the frame within convenient reach of the operator, said hand lever being provided with a suitable pawl and ratchet locking mechanism whereby said lever 24 and the parts shifted thereby are fastened in their adjusted positions.

Fixedly mounted on the main drive shaft 8 is a spudding cam 30 comprising a disk having on its outer edge laterally extendlng annular flanges 31 with which are adapted to be engaged bearing rollers 32 arranged on the ends of a grappling hook coupling member 33 the handle ends of which are in the form of overlapping hooks 34 which are adapted to hook into an eye or link 35 secured to one end of a spudding cable 36 the opposite end of which is adapted to be con nected with the tool operating cable 16 by means of the usual or any suitable form of sliding connection 37. By constructing the grappling hook coupling 33 as herein shown and described it will be seen that when the hook shaped handles 34 of the coupling are engaged with the eye or link 35 that the rollers 32 on the opposite ends or jaws of the coupling will be held in operative engagement with the flanges 31 of the spudding cam. By thus constructing and arranging the spudding mechanism the latter may be readily disconnected from the spudding cam and the tool operating cable when said cable is to be operated by the walking beam.

Revolubly mounted in suitable bearings in theforward end of the machine is a sand line shaft 38 on which is fixedly mounted the winding drum 39 of the sand bucket operating cable 40. On the end of the shaft 38 adjacent to the main drive pulley 7 is fixed a friction drive pulley 41 which is operatively engaged with the inner surface of the rim at the periphery of the main drive pulley 7 whereby said shaft 38 is driven in the proper direction for winding the cable 40. The end of the shaft 38 on which the pulley 41 is fixed is mounted in an eccentric sleeve 43 arranged in the adjacent bearing of the shaft and provided with a lever 44 whereby the same may be turned to shift this end of the shaft and thereby.

swing the friction pulley 41 into and out of engagement with the inner surface of the rim of the drive pulley 7 thereby throwing the shaft 38 into and out of operation.

Journaled in suitable bearings near the rear end of the machine is a casing line shaft 45 011 which is fixedly mounted a casing line reel or winding drum 46 on which is adapted to be wound the casing driving cable 47. On one end of the shaft 45 is loosely mounted a sprocket gear 48 which is connected by a sprocket chain 49 with a sprocket gear 50 fixed on the main drive shaft 8 as shown. The sprocket gear 48 is provided with one member of a clutch 51 the opposing member 52 of which is slidably keyed to the shaft 45 and is adapted to be thrown into and out of engagement with the clutch member of the gear 48 by means of a shifting lever 53 whereby said sprocket gear is locked to and released from the shaft 45 and the latter thus driven.

The tool operating cable 16, the sand bucket operating cable 40 and the casing driving cable 47 are each extended upwardly and are respectively engaged with

guide pulleys

54, 55 and 56 which are revolubly mounted in the upper end of the usual mast or derrick 57 arranged at the rear end of the machine and from said pulleys said cables extend downwardly and are connected with their respective operating devices.

On one end of the shafts 17 and 45 are mounted friction band pulleys 58 with which are engaged friction bands 59 one end of each of which is suitably fixed and the other end connected with an operating lever 60 whereby said bands may be drawn into frictionalengagement with the pulleys thereby stopping or retarding the movement of the shafts and the drums operated thereby.

By constructing and arranging the various parts of the machine in accordance with myinvention it will be seen that separate cables are provided for the spudding and drilling operation, the sand baling operation and the casing driving operation and that each of said cables is provided with a separate and independent operating mechanism having means for controlling or throwing the same into and out of operation.

Particular attention is invited to my improved means for actuating the drilling or tool operating cable during the spudding operation wherein a steady pull and quick release of the cable are provided for and which may be readily disconnected from the cable when the spudding operation is completed. Attention is also called to the improved arrangement of the various parts of the machine whereby space is provided adjacent to one side and near the rear end of the machine for a horizontal engine.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention claimed.
