Specification of Letters Patent.

Patented Feb. 13, 1906.

Application filed March 8, 1905. Serial No. 249,129.

To all whom it may concern; Be it known that 1, DAVID L. BAUGHER, a citizen of the United States, and a resident of Paola, in the county of Miami and State of Kansas, have invented new and useful Im-i rovements in Well-Drilling Machines, of which the following is a specification.

My invention relates to well-boring machines; and the object that I have in view in producing a machine of this character is its easiness of manipulation, its accurateness in execution, its cheapness in construction, and its susceptibility of long durability.

To this end my invention consists in certain novel features and combinations of parts, as will be illustrated in the drawings, and pointed out in the specification and the claims.

Referring now to the accompanying drawings, Figure 1 is a plan view of my invention, disclosing the position of a supporting rectangular frame and the position of the greater part of the mechanism comprising my invention mounted thereon. Fig. 2 is a side elevation-of the same, disclosing the supportingframe mounted on wheels. tudinal sectional view of a drum and a ratchetrim combined, taken on line AA in part of Fig. 1. Fig. 4 is a cross-sectional View of the same, taken on lineB B, also disclosing a con cave-faced pulley in plan, which will be fully described. Fig. 5 is a cross-sectional view of the concave-faced pulley referred to, taken on Fig. 6 is a cross-sectional view of a rope or cable clamp, taken on lineD D of Fig. 2 the object of which will be fully described. Fig. 7 is a vertical sectional view of the same, disclosing the rope or cable to be clamped in position. Fig. 8 is the upper end of a derrick which is secured to the front end of the machine as indicated at Fig. 2, the object being to support the cablein proper position when drilling or spudding the well. Fig.

9 is a section of a large wheel or pulley and a section of the supporting-frame as seen at Fig. 2, together with a small pulley which is eccentrically mounted on the frame and is adapted to engage and disengage the large pulley. Fig. 10 is a side elevation of a pulley the speed of which is adapted to be controlled by means of a brake-band. The position of said pulley is seen in Fig. 1, the plan view of my machine. Fig. 11 is an end view of the eccentric-bearing of shaft 89.

Fig. 3 is a longi- Having thus briefly described my invention, I will now proceed to fully describe it by referring to corresponding numerals on the drawings and the specification, in which 1 is a supporting-frame mounted on wheels 2. Horizontally mounted on said supportingframe are shafts 3, 4, and 5 and drums 6 and 7. Shaft 3 is strongly supported on bearings 8 and 9. Rigidly secured on one end of said shaft is a crank-arm 10, and rigidly secured on the outer end of shaft 5 is a segmental crank-arm 1 1. The face thereof is concave to conform to the configuration of a rope or cable in cross-section and is adapted to be engaged by either. Secured to the crank-arm 10 is a rope 12. The opposite end of said rope is secured to the segmental crank-arm 11. Said shaft is mounted on brackets 13 and 14, which are supported on a platform 15, mounted on the front end of the supportingframe 1. Rigidly secured to the inner end of said shaft 5 is a crank-arm 16. Mounted to the outer end of said crank-arm is a pulley 17. Said pulley is secured thereto by means of a bolt 18 and a yoke 19. To the opposite end of shaft 3 is mounted a large wheel or pulley 20, which is provided with a face or rim of sufficient width to be engaged by a frictionpulley on the inside of the rim without coming in contact with the spokes supporting the r1m.

Slidingly mounted on one end of shaft 4 is a small pinion or cog-wheel 21, and to the opposite end is rigidly secured a friction-pulley 22, which is adapted to engage and disengage the outer face of the wheel 20. Said shaft is firmly supported on the supporting-frame 1 by means of journal- bearings 23 and 24, as shown.

Drum 6 is mounted on a horizontal shaft 25 and is provided with a flange 26 at one end and a pulley-flange 27 at the opposite end, which is rigidly secured to shaft 25. Peripherally engaging said pulley is a brake-band 28. Said brake is manipulated and brought into tight frictional engagement and disengagement with said flange-pulley by means of a vertical lever 29, said lever being pivotally mounted to the supporting-frame 1 at 30 by means of a bolt 31 passing through the le ver and the frame. Said bolt is of sufficient length to first pass through an eye 32 on one end of the brake-band 28, as shown. The opposite end of said brake-band is pivotally secured to the lower end of lever 29. Pivotally secured to the upper end of said lever is a horizontally-inclined rod 33, which extends forward to the front end of the machine, as shown. Rigidly mounted on the opposite and outer end of said shaft is a cog-rimmed wheel or pinion 34, to which pinion 21 is adapted to alternately engage at stated times, which will be referred to farther on. Said shaft is also firmly supported on the supporting frame 1 by means of journalbearings and 36. Drum 7 is also supported on a horizontal shaft 37 by means of journal- bearings 38 and 39. Said drum is provided with flanges 40 and 41. The object of these flanges is to prevent confusion of the rope while winding on the drum. Mounted brake-band 44.

on one end of said shaft 37 is a combined cogged rim 42 and pulley or disk 43. Said cog-rim is adapted to be alternately engaged by pinion 21, which is slidably mounted on one end of shaft 4.

Loosely engaging the pulley or disk 43 is a One end of said band is secured to the supporting-frame 1 at 45. The other end is secured to a vertical lever 46 at 47, the lower end of said lever bein pivotally secured also to the supporting-frame 1 It will be noticed that the friction-pulley 22 is eccentrically mounted on shaft 4, as seen at Fig. 9, by means of an eccentric collar-bearing 49. Integral with bearin 49 is a vertical extended arm 50. Pivotal y connecting said arm is a horizontallyinclined rod 51, which extends forward, as shown, with a handhold 52 in the end.

Brackets 13 and 14 are resting on a bedplate 53, as seen at Fig. 3, Shaft 5, which is loosely mounted on said brackets, is held securely in osition by j ournal-caps 54 and 55. Said shaft 5 is adapted to oscillate in its bearings and will bereferred to farther on. Loosely mounted on said shaft is a combined recessed drum 56 and ratchet-rim 57: The recessed drum is provided with flanges 58 and 59 and is adapted to accommodate or control the movements of two diflerent ropes, one being carried between the two flanges 58 and 59 over the recessed portion 58 and the other over the extended portion 59 between the ratchet-rim 57 and the flange 58. The obj ect of these flanges is to maintain the Winding-ropes in proper position on the drum.

Pivotally mounted at the front end of the machine is a horizontally-arranged lever 60, the inner end being bent upward and extended beyond the pivotal point 61. Pivotally secured to the lever 60 is a dog 62, and pivotally secured to said lever slightly below the pivotal point 61 is another dog 63. The dogs are held in proper position for engagement with ratchet-rim 57 by means of a resilient spring 64 and 65, as shown.

I have shown in connection with my invention the usual samson post 66, employed as a part of most well-boring machines for supporting walking-beams, &c., which I do not lay claim to as a part of my invention or as a part of my machine. This post and its immediate auxiliaries I can dispense with with-' out affecting the validity of my invention. Mounted on said post is a pulley 67, the object of which is to support a rope 68 in an elevated position extending from drum 6 to drum 56. The drum 6 and this rope 68, together with the portion 59 of said drum 56, are for backing or raising the boring-tools from the well.

Extending from drum 7 upward and over pulley 69, which is mounted on the upper end of a derrick 70, (seen at Fig. 8,) is a rope or cable 71. The boring or spudding tools referred to are to be secured to the depending or free end of said rope. As the spudding movement proceeds the spudding-tools descend into the earth, but necessarily have to be raised from the incomplete well a number of times before completion. The 0 posite end of said rope 71 is made secure to (fium 7, already referred to as seen in Fig. 1, then up and over pulley 69. In order to save the wear and tear of rope 71 and to facilitate in its movements, I have provided a rope-clamp 72, (seen in position on rope 71 at Fig. 2 and Fig. 8, also in cross-section at Fig. 6 and ver-' tical section at Fig. 7,) which is composed of a horizontal tongs-like pair of clamping- jaws 73 and 74, pivotally secured together at 75 and opened and closed by a T-bolt 76, as shown, and held in position by said clamps are a pair of vertical rope-clamping aws 77 and 78. These jaws are so constructed that they will automatically tighten as the stress of a short rope is increased between the clamp and drum 56, the object of and description of which will be fully described later on.

Extending down from ears 79 and 80, integral with clamps 73 and 74, are a pair of links or depending bails 81 and 82, their lower ends coming together at 83. Secured to these lower ends is the upper end of a short rope 84, which extends down over pulley 17, and made secure to drum 56, rigid to derrick 70, (seen at Fig. 8,) is a pin or bracket 85. Secured to said bracket and the upper ends of the clamping- jaws 77 and 78 at 86 is a coilspring 87. I have further provided a resilient spring 88, secured to bed-plate 53, the object of said spring being to impart a more speedy movement to the oscillating shaft 5. The upper end of this spring engages under crank-arm 16. (Seen partly in dotted lines at Fig. 4.) I have also provided a shaft 89 with a friction-pulley 90 on one end, which is adapted to engage the inner face of rim 20 of the driving-wheel. Said pulley is made to engage and disengage said rim by means of an eccentric-bearing. (Shown in Fig. 11.) Said shaft passes through an eccentric 101,

Biases which is rotatably mounted in a bearing 102 and is provided with a lever 105, by which it may be turned. Said shaft is mounted on the supporting-frame 1 by means of journalseats 91 and 92. Said shaft is to be utilized for hoisting mud, water, and other matter that accumulates in a well during the boring process, which is accomplished by means of a rope or cable 93. Secured to the shaft 89, as shown extending upward and over a pulley 94, is a sand-line 93, from which is suspended a bailing-bucket-95. Said pulley 94 is supported by the derrick 7 O.

Rope 12 is secured to crank-arm 10 by a wrist-pin 97. Said crank-arm is provided with a plurality of openings, as shown, the object of these being to shorten or extend the oscillating movement of the segmental arm 11, and I have furtherprovided wrist-pins 101 and 102, as indicated, in arm 10 and segmental arm 11, the object being to effect the movement of shaft 5 with a stiff rod instead of a rope, if so desired.

The operation of my invention is as follows: The driving-wheel is first put in motion by any kind of suitable power, this causing crank-arm 10 to revolve, rope 12 being secured to said arm, and the segmental arm 11 causes shaft 5 and arm 16, carrying pulley 17, to oscillate, one end of rope 84 being secured to drum 56. The opposite end passes up-' ward through yoke 19 and partly around pulley 17,up, and made secure at 83 to ropeclamp 72. Said rope-clamp is secured to rope 71. Each revolution of driving-wheel 20 causes segmental arm 11 to oscillate to about the extent of its segmental diameter, its rearward movement causing rope 84 to a certain degree to fold or double and at the same time causing spiral spring 87 to distend. It can now be seen that this movement will draw that portion of rope 71 that is above the clamp 72 downward over pulley 69, raising the depending end of said rope and the spudding-tool, which I will designate 98 and 99, upward, so that on each revolution of driving-wheel 20 the spudding-tool, with the assistance of spring 88, will make a quick downward stroke into the incomplete well. In using my rope-clamp 72 it enables me to entirely dispense with the samsonpost 66, if I wish to do so, and thus save the wear and tear of a long rope or cable for wellboring purposes. As the boring progresses the rope 84 slowly unwinds from drum 56, and clamp 72 will gradually rise until it nears the projecting pin 85. In the meantime spring 87 is contracting, which materially assists the upward movement of the ropeclamp. I/Vhen at this point said clamp is lowered to its normal position, as seen in Fig. 8, this movement slackens rope 84, which by reversing drum 56 is rewound thereon, when the drilling movement is ready to be proceeded with. The movements of said drum 56 is under full control of lever while the drilling of the well is in progress, which is manipulated by the drilling operator. Said drum 56 can be more speedily actuated by the manipulation of rod 51 by first putting pinion 21 in engagement with cog-rim 34 and then bringing pulley 22 in engagement with driving-wheel 20. Either of the movements can be employed for raising or lowering the tools. When the tools are to be raised out of the well, I relax my rope-clamp 72, and with a direct pull on rope 71 by first readjusting pinion 21 to its present position the tools will be speedily raised; but in the event the machinery should becomedisabled,

and in the meantime it is expedient to raise the tools from the well, the rack-bar 60 is wholly relied upon in such instances.

Shaft 89 and rope 93, passing over pulley 94, mounted on derrick 70, are for raising water and other matter from the well incident to the boring thereof.

The movements and speed of my well-boring machine are all controlled by brake bands and levers.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a well-drilling machine, the combination of a supporting frame, an {oscillating shaft mounted thereon, a segmental arm fixed upon one end of said shaft, a crank-arm fixed upon the opposite end, a drum and a ratchetrim loosely supported on said shaft, an arm 1() a shaft 3, and a ratchet-lever carrying a pawl which engages said ratchet-rim, substantially as described.
