WELL-DRILLING MACHINE.

Application filed August 24, 1917.

To all :whom, it may concern: 7

Be it known that I, WVILLIAM C. SOLE, a

- citizen of the United States, and a resident scription.

My invention has for its object to provide a portable well drilling machine which embodies the good qualities of a stationary machine.

The machine is provided with a calf reel,

3 and in the rear of the calf reel a bull reel,

the calf reel having a casing line and the bull reel having a drilling cable. On the calf reel there is mounted a spudding pulley under which the drilling cable may be disposed so that the calf reel may be rocked by means provided for spudding purposes.

Additional objects of the invention will appear in the following specification, in which the preferred form of the invention is disclosed.

In the drawings similar reference characters denote similar parts in all the views, in which Figure 1 is a sectional view on the line 11 of Fig. 3;

Fig. 2 is a. side elevation as indicated by the arrows at 22 in Fig. 3; and

referring to the drawings, it will be seen that the well drilling machine is provided with a frame 15 with supporting wheels 16 by whichv the machine may be moved from place to place, it being possible to secure the supporting wheels 16 on sills 17 when the machine has been moved to the place where it is to be used. The main mast 19 is mounted on one of the transverse sills 18 which are employed to hold the supporting Wheels 16 against rotation on the sills 17 The main mast leans forwardly, and is supported in this position by auxiliary masts 20 which are secured to the main mast 19 by brackets 21. There are three sheaves on the main mast 19,a crown sheave 22, a sheave 23 for the casing line 35, and a sand sheave 24. J ournaled in bearings 25 in the frame 15 there is a calf reel shaft 26 having a calf reel 27 a bull reel shaft 28 beingjournaled in bearings 29 in the frame 15 and having a bull reel 30 which extends from one side of the frame to the other. A drilling cable 31 Specification of Letters Patent.

is disposed around this bull reel 30, and at all times except when it is desired to spud, the drilling cable 31 passes from the bull reel 30 directly to the crown sheave 22; but when it is desired to spud, the casing line, which is normally on the calf shaft 26, is loosened and is disposed beyond the main mast 19, when the drilling cable 31 is disposed under a spudding pulley 32 mounted on an arm 33 bolted to a flange 34 on the calf reel 27. The calf reel 27 is then rocked by means which I will shortly describe, by which means the drilling cable 31 is pulled periodically to accomplish the desired result.

It will be understood that with the arrangement which has been described, it is possible to discontinue spudding and commence to drill merely by disengaging the drilling cable 31 from the spudding pulley 32. The casing line 35 being at all times in position for use. It is merely necessary to disengage the drilling cable 31 from the spudding pulley 32 to permit of the use of the casing line.

A sand line 36 is disposed over the sand shaft 24, and leads to a sand reel 37. The casing line 35 is the fall of a tackle 38. As has been stated, the casing line 35, the drilling cable 31, and the sand line 36 are permanently installed, and it is never necessary to substitute one cable or line for another. Not only is this true, but at no time will the cables cross each other to cause unnecessary wear. When spudding, the calf reel shaft 26 is given a rocking movement by means of a pitman 39, which connects a wrist pin 40 on a pulley 41 with a wrist pin 42 on a pulley 43 mounted on the calf reel shaft 26. It will be understood that the wrist pin 40 has a shorter radius than the wrist pin 42, so that the calf reel shaft 26 will have a rocking movement, although the pulley 41 rotates in one direction with the continuous rotation of a band wheel shaft 44. The band wheel shaft 44 is rotated by a cable 45 which connects a pulley 46 with a pulley 47 on the band wheel shaft, the pulley 46 being driven by an engine or other means 48. The engine 48 is mounted on a separate frame 49 which is held spaced from the frame 15 by a jack 50, this means being provided to keep the cable 45 taut. When the spudding operation has been completed, the pitman 39 is removed and the pulleys 41 and 43 are connected by a cable, when the casing line 35 is to be used. The

cable, which is preferably a wire rope shown by the dotted lines at 51, is given one and one-half turns around each of the pulleys 52 and 53; but when the casing is very heavy and hard to pull, the wire rope is removed from the pulley 52 and disposed around the pulley 41, which is secured to the pulley 52, the wire rope being also removed from the pulley 53 and being disposed around the pulley 13 which is secured to the pulley 53. While the pulleys 13 and 53 are of the same diameter, the diameter of the pulley l1 is less than the diameter of the pulley 52, so that while the wire rope will be disposed one and one-half times around the pulley 43, it will be disposed two and one-half times around the pulley 1-1. The band wheel shaft 44 is journaled in bearings 54, and secured to this band wheel shaft there is a metal friction wheel 55. The sand reel shaft 56 on which the sand reel 37 is secured, carries a friction wheel '57 having preferably a wooden face, it being possible to move the sand reel shaft 56 so that the friction wheel 57 will be brought into engagement with'the friction wheel 55 on the band wheel shaft i i- 1, or with a brake shoe 58 mounted. on the frame 15. The friction Wheel 55 not only is adapted to drive the sand reel shaft. 56 by means of the friction wheel 57, but the friction wheel 55 is also adapted to engage a friction wheelv 59.0n a countershaft 60, it being possible to move the countershaft 60 so that the friction Wheel 59 will engage the friction wheel 55 or a brake shoe 6'1 carried by vthe frame. The friction Wheel 59, as well as the friction wheel 57, is provided with a wooden face. The-countershaft 60-serves to drive the bull reel 30 by a; means which I will shortly describe. At one side of the frame the sand reel shaft 56 andthe countershaft 60 are journaled insimilar bearings 62, and at the'otherwside of the frame the sand reel shaft 56 isjournaled in a bearing 63and the countershaft 60 is journaled in a bearing 64:, the bearings 63 and 64 being pivoted as shOWn in Fig. 2 of the drawings. The bearing 63. has an upwardly extending lever 65 and'thc bearing 64 has a dependinglever 66, by which means the bearings ing at the main mast 19 may regulate the movement of the shafts 56 and 60 to bring the frictionwheels 57 and 59 into frictional engagement with the friction wheel 55, the bearings 62, 63 and 64being self-alining as has been stated. In addition, tothe levers 62 and 68, there are levers 71 and Y72, the lever '71 being provided for operating the brake-band 73, mounted on a brake drum carried by the calf reel shaft 26. The lever 72 is provided for operating the brake-band 7st disposed around a brake drum carried by the bull reelshaft 28.

As has been stated, the countershaft 60 is used for driving the bull reel shaft 28. The countershaft 60 and the bull reel shaft 28 are connected by sprocket wheels. 75 and 76 and a sprocket chain. 77.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

In a well drilling machine, a mast, two shafts, one having a calf reel secured thereto on which a casing line is normally disposed, means to rock the last mentioned shaft, the other shaft having a bull reel, a spudding member mounted on the-calf reel,

a pulley on the mast, and a drilling cable disposed over the pulleyand around the bull reel, the cable being adapted. to be disposed under the spudding-member.
