JAMES S. OLIVER-,YADOLFHUS D. OLIVER, AND NOBLE B. OLIVER, OF SAN ANGELO,

TEXAS.

WELL-DRILLING MACHINE.

Application mea May 1s, i923. serial No. 639,328.

To aZZ whom t may concern:

Be it known that we, JAMES S. Ouvrir, ADoLrHUs D. OLIVER, and NOBLE B. OLIVER, citizens of the United States, residing at San Angelo, in the county of Tom Green and State of Texas, have invented certain new and useful Improvements in Tell-Drilling Machines, of which `the following is a speci# ication.

This invention relates to well drillingma-` chines, and has'for one of its objects to improve the construction and increase the efliciency and utility of devices of this character.

Another object of the invention is to provide a device of this character capable of bei i ing transported, from place to place and transportation or storage.v

With these and other objects in view, invention consists in certain novel features of construction as hereinafter shown and described and then specificallyv pointed out in the claim, and in the drawings illustrative.

of the preferred embodiment of the invention.

` Figure 1 is a side elevation from one side,r

and

Fig. 2 is a side elevation from thev opposite side.

Fig 3 is a plan View, with the supporting frame in section on the line 3 3 of Fig. 1.

Fig.v 4 is anl enlarged Vdetail in section on the line 4 4 of Fig. 1.

Fig. 5 isan enlarged sectional detail of.

the tension device.

Fig. 6 is anenlarged detail, partly in section, ofthe vgear shifting mechanism. i

Figure7 is an enlarged sideview partly in section of the adjustable bearings of the winding drum shaft and the shipper shaft. The improved apparatus includes an ob-y long base frame of spaced side V'rails 10-11, transverse end vmembers12 and 13, an intermediate transverse member '14,' vertical rear corner members or posts 15, forward corner posts 16, upper rear transverse frame members 17 and obliquely directed braces 18 f land 19.

wardly, slightly,

vThe forward posts 16 are inclined outd as shown in Figs'l and 2, and are likewise extended above the Iline of the braces 18,

thev

` guide rlfhe rear posts 15 are likewise extended upwardly and are provided with bearings 2O which support a transverseshaft 21 on which n a cable guide pulley 21 is mounted.

A` short longitudinal frame member 22 is supported on the

frame members

12 and 14, and carries a bearing 23 coacting with a similar bearing 24 on the rail 10, to support The beam is provided with a cable guide pulley 31 intermediate the ends, as shown.

Attached to the forward posts 16 are transverse supports 32 and 33, and connected to these supports are spaced vertical guides 34 between which the free end of the beam 28 operatesA and by which it is prevented from lateral displacement.

The mast portion of the improved apparatus constitutes an extension of the forward posts 16 and is represented as a whole Lat 35. and hingedly united at 36`to the posts,

so that the mast can be folded down as indicated by dotted lines in Fig. 1'. Braces 37 are detachably connected as at 38 and 39 to the posts -15 and mast 35, and hold Vthe mast in vertical and operativeposition, but will be releasable to permit the mast to be folded, as will be obvious. At its upper end,

the mast is provided with a cross head 40 carrying cable guide pulleys 41 and 42 for the sand pump line 43, and with a cable pulley 44 for the main drill line 45.

Mounted for rotationby bearings 46 on the

yframe members

10 and 11 is a main drive shaft 47 carrying a drive pulley 48 operative by a drive belt 49 from any suitable source of power, not shown.

`Mounted loosely on they shaft 47 is a beltv pulley 50 in alinement with'vthe band pulley 26 and with an endless drive belt 51 operating over the pulleys.

The pulley 50 is formed with an internal friction clutch face with which a cone clutch `member 52 Slidable on the shaft 47 is adapt- .at 66 and 67.

Slidably supported by guide members 56 and 57 on the

frame members

10 and 11 is a shipper rod 58, and connected to the shipper rod is a yoke device 59, the latter engaging in an annular groove in the sleeve 54. By this arrangement whenthe shipper rod is moved longitudinally in one direction, -the clutch member 50 will be forced into contact with the member 52 and transmit the niotioii of the shaft 47 to the belt wheel 26, and when the shipper rod is moved in the opposite direction, the clutch members will besepai'ated and thev ii'iot-ioii'of the belt pul. ley stopped. l

At one end the rod 58 is forked as shown at 60 and provided with transverse pins 61 through the forks. Mounted for rotation in hangers 62 on the frame members 11 is a rod 68 having the ends upturned as at 64 and 65, the portion 64 kevtending upwardly between the .pins 61 and preferably curved as shown in F ig. 6 to reduce lthe friction, while the pins 61 are also preferably provided with antifrietion rollers as shown in Fig. 6, for the same purpose. The upturned portion 65 constitutes a hand lever -by which the rod 63 maybe rotated. The lever member 65 is arranged to be held in adjusted position in any suitable means, such .as by atoothed segment aud pawl device indicated By this arrangement, the clutch member 52 is operative from the vicinity of the mast 35, as willbe obvious.

Attached to the frame member 10 is a swivel bearing 67', and slidably mounted on the frame member 11 is a bearing v68, the bear-ings supporting a shaft 69 on which the sand line `winding drum lp70 is .mounted for rotation with the shaft.

Attached to the frame member 10 is a bearing 71, and mounted on the member 11 is a like bearing 72, the .latter bearings supporting a shaft 7 8 which `carries a cable windingdrum 74 for main drill Cable 45.

Attached ,to the frame `.member 10 is a swivel bearing 75, and slidably mounted on the .frame member 11 is a bearing 76, .the latter bearings ,supporting a shaft 77.

The shafts 7 Sand 77 are provided-respectively with Vengaging gear 78 and pinion 79, to 'provide for the -rctatioirofthe shaft 7 8 from the shaft 77.

The shaft 47 is extended beyondthe frame member 11 and is provided with a friction drum 80, .while'the shafts 69 and.73 areprof vided respectively with `friction .

drums

81 and 82.

svvinginglysupported at 89 and,90.

Y The flevers are `provided respectivelyiwith cam devices coupledto therods 8,3 .and 84, to enable the rods to be independently moved longitudinally to draw the

drinn

81 or 82 into engagement with .the central drum 80, and transmit the motion of the shaft 47 to either of the

shafts

69 or 73, from a position near the mast.

Thus by manipulating the three levers -65-*87 and 88, the motion of the shaft 47 may `be transmitted to the main band wheel 26 and thence to the beam 28, or to either the

Winding drum

70 or 74 the object to be hereinafter explained.

Attached to the post members 15 and to the .braces `19 are .brackets 91, aud-attached to the upper horizontal sides of the brackets are gear racks92. Y

Attached across the .post membersl is a support 93, and slidable through the support near the ends vare pull rods 94, each rod being provided with a pullspring 95 ,and stop plate 96 and operating to hold vthe rods yieldably in outer position. vAt its .inner end, each rod is connected to a bearing 97,

and mounted for rotation throughthe ,bearings is a shaft 98, and mounted on the,l shaft and rotative therewith are gear pinions 99` .drive belt 49, ,and the rod 6 3 actuated by the hand lever 65 to close the clutch device 52 and ytransmit motion vtothe main band .wheel 26 and thence to the crank 27, connecting bar 101, and ,beam 28, and cause the pulley 31 to actuate the drill cable. As the k beam 28 is operatedaiid strain applied to the drill cable, corresponding strain is applied to the shaft98, and `the latter vmoved against the resistance of the springs 95, to thustake upl the slack of thedrill cable and keep it in taut condition.

As the drilling .proceds, the drum 74 is slacked `up. to permit the `drill cable .to be drawn out as fast as required. .As the cable `is wound upon the drum 74, itconstantly moves 4toward one `end of the drum, consequently the guide lpulley 100, which slides freely 'on the shaft ..98 will be correspondkiiigly moved longitudinally of theshaft and this ,lateral movement of the pulley changes the pull ,orleverageon the shaft'98, but by coupling the ends of the shaft tothe racks 92 by the pinions 99lthe shaft is maintained constantly? at ,rightang-les to the frame members 1() and l1, no matter where thelpu'lley 100 is located on the shaft 98.

If the cable is to be wound upon the drum 74, the lever 88 is moved rearwardly to force the friction drum 81 into engagementwith the central power drum 80.

If the sand line is to be Wound upon the drum 70, the lever 87 is actuated to apply a pulling force to the rod 84 and thus move the drum 81 into engagement with the central drum 80.

Thus the various motions are all accomplished by simply manipulating the three

small levers

65, 87, and 88, as before described, the levers being independently operative.

The apparatus will preferably be mounted on carrier wheels indicated at 102.

A suitable brake device is arranged to check the friction pulley 82, while a similar brake device 103 which is attached to the ad-l jacent sill member 11 of the supporting frame checks the pulleyr81.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specication, but it will be understood that modifications within the scope of the claim may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

What is claimed is In an apparatus of the class described, a supporting frame, a mast extending from said frame and carrying a cable uide pulley, a beam swinging from said rame and carrying a. cable guide pulley, spaced rack bars supported on said frame, a shaft carrying gear pinions engaging said rack bars, a cable guide pulley carried by said shaft,

bearings engaging said shaft, pull rods eX- tending from said bearings, springs engaging said rods and operating to hold said shaft yieldably in position, and a cable attached at one end relative to said frame and leading over said several cable guide pulleys.

In testimony whereof, we alix our signatures hereto.v
