Application filed December 30, 1910. Serial No. 600,099.

To all whom it may concern:

Be it known that I, STEUBEN D. WHAM, a citizen of the United States, residing at Elgin, in the county of Comanche and State of Oklahoma, have invented a new and useful WVelLDrill, of which the following is a specification.

It is the object of this invention to provide, in a well drilling machine, novel means for actuating the jerk line, to provide .novel means for actuating the drill hoist rope and the slush-rope, to provide novel means for operatively connecting the jerk line actuating mechanism, the hoisting mechanism, and the slush-line mechanism with the source of power, and to improve generally, the construction of well-drilling machines.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed with out departing from the spirit of the invention.

In the drawings;Figure 1 is a longitudinal section wherein sundry details appear in elevation; Fig. 2 is a transverse section at right angles to the cutting plane of Fig. 1, parts being in elevation, and parts being broken away; Fig. 3 is a top plan, parts being removed; Fig. 4 is atransverse section of the drill rope hoisting drum, the view being designed to show particularly, the brake whereby the drum is controlled; Fig. 5 is a sectional elevation of the shafts whereby the drill rope hoisting drum and the jerk line mechanism are operated, the view showing the mechanism whereby the shafts may be operatively connected; Fig. 6 is a sectional elevation of the slush rope drum and its actuating shaft; Fig. 7 is a detail section, in a horizontal plane, of the pawl and ratchet mechanism whereby the jerk line is actuated, the view showing the parts in the positions which they will assume when the jerk line is about to be moved by the shaft whereby the jerk line is actuated; Fig. 8 is a similar view showing the parts in the positions which they will assume after the jerk line mechanism has been rotated by the shaft, to the limit of its travel; and Fig. 9 is a vertical transverse section of the mechanism depicted in Fig. 7

The supporting structure involves, as'primary and fundamental elements, a frame, and a platform which is rotatably mounted upon the frame. The frame 1 may be of any desired construction, so that it may be mounted fixedly upon the ground, or disposed upon wheels for transportation. The frame includes a hexagonal portion 2, the constituent elements of the frame being suitably braced, in any desired manner, as shown at 3. The hexagonal portion 2 of the frame supports a circular track 4. Fixed to the frame 1 and rising above the same, is a tubular pivot member 5, located at the center of the track 4:, and constituting a support upon which the platform is mounted for rotation in a horizontal plane.

The platform preferably consists of sills 6, converging into union at a point well be yond the periphery of the frame 1. To the lower faces of the sills 6, a flooring 7 is secured. Into this flooring 7, the pivot member 5 protrudes, thus affording a rotatable mounting for the platform. The lower face of the flooring 7 is equipped with spaced shoes 8, adapted to bear upon the track 4, and at the point of confluence of the sills 6, a clevis 9, or the like is mounted, whereby one or more draft animals may be connected with the platform, to secure a rotation thereof upon the pivot member 5, the rotation of the platform upon the frame 1 serving, as will be pointed out hereinafter, to actuate the several mechanisms which the supporting structure carries.

Secured to the flooring 7 and disposed between the sills 6, transversely of the same, is a brace 10. Fixed to and rising from the frame 1, adjacent one end thereof, are spaced uprights 11, connected by transverse cross bars, numbered consecutively from the bottom of the structure toward the top as at 12, 14, 15 and 16.

The derrick consists of converging lower members 17, preferably secured to the flooring 7 by means of brackets 18. Alined with the lower members 17 and converging upwardly, are the upper members 19 of the derrick, the derrick being disposed in close proximity to the pivot member 5. The lower members 17 of the derrick are hinged, as shown at 20, to the upper members 19, the construction being such that the upper members 19 may be folded downwardly and inwardly, so as to dispose the derrick in small compass. To the outer faces of the members 17 and 19, removable fish plates 21 are applied, so as to maintain the constituent elements of the derrick in proper relation to each other, when the derrick is set upright for use, as shown in Fig. 2.

A diagonally disposed brace 22 extends upwardly from the meeting point of the sills 6 of the platform, into union with the upper ends of the members 19 of the derrick, this brace 22 obviously serving to uphold the derrick, the brace 22 being removably connected with the elements which it unites, to provide for a knocking down of the structure. Other diagonally disposed braces 23 extend downwardly from the upper ends of 'the uprights 11, into union with the free ends of the sills 6 of the platform, the braces 23 serving as a means for upholdingthe uprights. To these braces 23, the derrick may be connected, as indicated at 23' in Fig. 1.

Rotatably mounted in bearings 24, secured to the cross bars 15 and 16, is a hoist shaft 25, carrying a hoisting drum 26. The drill rope 27 is wound about the hoisting drum 26, and passes over a sheave 28, rotatab-ly mounted in the free end of an arm 29, consisting of diverging members 30, pivoted as shown at 35 to the uprights 11. Above the sheave 28, the drill rope 27 is passed over a sheave 31, supported between hangers 32, depending from the upper extremity of the derrick, the free end of the drill rope 27 being carried downwardly through the tubular pivot member 5, into the tubing of the well.

A drive shaft 33 is rotatably mounted in bearings 34, secured, (as shown in Fig. 9,) to the cross bars 12 and 14 of the platform, the drive shaft 33 being in vertical alinement with the hoisting shaft 25.

As seen to best advantage in Fig. 5, the adjacent ends of the shafts 25 and 33 are squared as at 35. A collar 36 is slidable upon the squared portion 35 of the shaft 25, the collar being adapted to be lowered to engage the squared end 35 of the shaft 33 so as to unite the shafts 25 and 33 for simultaneous rotation. The collar 36 may be manipulated in any desired manner. For instance, a lever 37, fulcrumed at 38 upon a bracket 39 secured to the cross bars 14 and 15, may be equipped with spaced fingers 37 (see Fig. 5), adapted to engage the collar 36 to raise and lower the same, without interfering'with the rotation of the collar. The free end of the lever 37 may be engaged with a standard 87, to maintain the collar 36 in the uplifted position shown in Fig. 5, the standard 87 being fixed to the flooring 7, or to any other convenient rigid portion of the device.

Rotatably mounted upon the shaft 33 and preferably disposed between the cross bars 12 and 14, as shown in Fig. 9, is a two-part, segmental casing 40. Located within the casing 40, and secured to the shaft 33, is a ratchet 41. This ratchet, referring particularly to Figs. 7 and 8, is adapted to be engaged by a pawl 42, having diverging, curvilinear ends 43 and 44, the ends of the pawl being pivotally united with the casing 40 by means of links 45, certain of the securing elements whereby the two constituent elements of the casing 40 are held together, ordinarily constituting the pivotal mountings of the links 45, as shown at 46. The casing 40 carries an upstanding lug 47, adapted to engage the end 43 of the pawl, under circumstances to be described hereinafter.

Secured to one of the sills 6 is a transverse bracket 47, carrying an arm 48, adapted to engage the end 43 of the pawl, as will be described hereinafter. The arm 48 may be adjustably mounted upon the bracket 47 in any desired manner. For instance, openings 49 may be fashioned in the arm 48, and a bolt 50, or like securing element may be mounted successively in the openings 49, to unite the arm 48 with the bracket 47. A rod 51 is held for sliding movement beneath a clip 52, attached to one of the sills 6, this rod 51 terminating at its inner end in a spring finger 53, adapted to engage the end 44 of thev pawl.

One of the securing elements which unites the constituent portions of the casing 40, may be employed, as shown at 54, to engage one end of the jerk-line 55. The outer edge of the casing 40 is curvilinear in outline, and is grooved, as shown at 56, so that the jerk line 55 may be partially wound about tlje casing 40, as will be explained hereina 'ter.

The erk line 55, extending from the casing 40, is passed about the sheave 57 mounted upon the brace 10. Above the sheave 57, the jerk line extends upwardly into union with a link 58, supported upon the pivot element 59 whereby the sheave 28 is held for rotation upon the arm 29.

Under normal working conditions, the collar 36 is disposed as shown in Fig. 5, the shaft 33 being free to rotate, independently of the shaft 25. Referring to Figs. 7 and 8, and noting Fig. 7 in the first instance, let it be supposed that the shaft 33 is rotated in the direction of the arrows. Under such circumstances, the ratchet 41 will engage the pawl 42 and swing the casing 40 in the direction of the arrows, pivotal movement between the pawl 42 and the casing 40 being prevented by the engagement between the end 43 of the pawl and the lug 47.

A continued rotation of the shaft 33 will carry the casing into the position shown in Fig. 8, the extremity of the portion 43 of the pawl coming into contact with the arm 48. This contact between the portion 43 of the pawl and the arm 48, will move the pawl proper 42 out of engagement with the teeth of the ratchet 41, whereupon the casing 40,

being actuated by the weight of the drill,

will swing into the dotted line position shown in Fig. 8. Presupposing that the finger 53 upon the end of the rod 51 is positioned as shown in Fig. 7, it will be seen that this finger 53, engaging the end 44 of the pawl, will advance the pawl proper 42 into engagement with the ratchet 41, thereby to swing the casing again'into the position shown in Fig. 8. Obviously, as the casing 40 thus oscillates, the jerk line 55 will be reeled into the groove 56 and released, causing a reciprocation of the jerk line, and consequently a tilting of the arm 29, the tilting movement of the arm 29 causing a reciprocation of the drill rope 27 and producing the required action of the drill in the well.

The operation to reel the drill rope upon the drum 26 is as follows. Presupposing that the collar 36 is in the position shown in Fig. 5, the lever 37 is manipulated to lower the collar, so that it will engage the squared end 35' of the shaft 33, thus connecting the shaft 33 operatively with the shaft 25. During the operation of raising or lowering the drill, the jerk line I55 should not be operated. In order to render the jerk line 55 temporarily inactive, the rod 51 is retracted into the position shown in Fig. 8, so that the finger 53 upon the end of the rod 51 will be withdrawn from the path of the end 44 of the pawl. In such case, the pawl proper 42 will remain, as shown in dotted lines in Fig. 8, out of engagement with the ratchet 41. Therefore, when the shaft 33 is rotated, by mechanism to be described hereinafter, the casing 40 will remain in fixed position, the jerk line 55 being at rest. The shaft 33, however, being operatively connected with the shaft 25, will cause a rotation of the drum 26, reeling in the drill rope 27 over the sheaves 28 and 31.

Supported for rotation in bearings 61, secured to the cross bars 12, 14 and 15, is a shaft 60, located out of alinement with the shafts 25 and 33. The shaft 60 carries a winding drum 62, one end of the shaft 60 being denoted by the numeral 63. The drum 62 is, as shown in Fig. 6, normally held uplifted by means of a lever 64, fulcrumed upon a bracket 65, attached to the cross bar 14, the lever 64 being equipped with fingers 66 which engage the drum to lift the same, without interfering with the rotation of the drum. The drum 62 and the shaft 60 are provided with polygonal interlocking ele ments 67 located adjacent the end 63 of the shaft, whereby a rotation of the shaft 60 will produce a rotation of the drum 62, when the interlocking elements 67 are in engagement, the drum 62 being normally maintained in the uplifted position shown in Fig. 6 by the engagement between the free end of the lever 64 and a standard 68, fixed to and rising from the flooring 7 of the platform. The slush-rope 69 is wound about the drum 62, the slush-rope being carried through a sheave 70 secured to one of the lower members 17 of the derrick, the slushrope thence extending upwardly through another sheave 71, secured to one of the upper members 19 of the derrick, The free end of the slush-rope is carried downwardly, and may be temporarily secured, as shown at 72 to the cross bar 15. As will beexplained hereinafter, the shaft 60 is in continuous rotation when the device is in use, the drum 62 being lowered into operative engagement with the shaft 60, when it is desired to use the slush-rope 69.

As will appear hereinafter, the shaft 33 is rotated simultaneously with the shaft 60. It has been pointed out hereinbefore that the jerk line 55 may be rendered inoperative from the shaft 33, and Fig. 5 will serve to show that the drum 26 may likewise be maintained inoperative from the shaft 33. Un-

der such conditions, the shaft 60 will rotate, to actuate the drum 62, thereby to manipulate the slush-rope 69. In order to hold the drum 26 against rotation when, as shown in Fig. 5, the shaft 25 is disconnected from the shaft 33, one end 73 (see Fig. 4) of the drum 26 is surrounded by a strap brake 74, secured at one end, as shown at 75, to the cross bar 15, the other extremity of the strap brake being attached to the intermediate portion of an upright lever 76, fulcrumed as shown at 77, to one of the uprights 11, the movement of the lever 76 being controlled by a rod 7'8, one end of which is pivoted to the lever, the other end of the rod being pivoted to an operating member 79, fulcrumed adjacent its lower end upon one of the sills 6, the operating member being provided with suitable latch mechanism to engage a segment 80, preferably carried by one of the braces 23.

A variety of mechanisms may be employed for securing a rotation of the shafts 33 and 60. For instance, a sprocket chain or other flexible member 82 may be passed around the periphery of the polygonal portion 2 of the frame, and held therein by outstanding fingers 81. This chain 82 may be engaged with a sprocket wheel 83 upon the shaft 60, and with a sprocket wheel 84 upon the shaft 33. To one of the sills 6, a belt tightener 85 may be attached, the tightener 85 carrying a sprocket wheel 86, engaging the interior of the chain 82, to maintain the same at the desired tension.

The chain 82 will be held fixed upon the hexagonal portion 2 of the frame, and when one or more draft animals are attached to the clevis 9, the platform, including the sills 6, may be rotated upon the frame 1, the pivot element 5 acting as a center. When the platform is thus rotated upon the frame, the chain 82 will engage the sprocket wheels 83 and 84:, causing a rotation of the shafts 60 and 33, respectively.

Under ordinary conditions, the shafts 33 and 25 are spaced apart, as shown in Fig. 5, the drum 26 being maintained against rotation by means of the strap brake 74. Likewise, the drum 62 is, as shown in Fig. 6, maintained out of operative engagement with the shaft 60. Under such circumstances, the casing 40 is the primary operative member of the structure, and as the platform is rotated upon the pivot element 5, through the instrumentality of the sills 6, the sprocket wheel 84, passing along the fixed chain 82, will cause a rotation of the shaft 33, the rotation of the shaft 38 operating, as hereinbefore described in connection with Figs. 7 and 8, to actuate the jerk line 55, thereby causing a reciprocation of the drill and the drill rope.

As hereinbefore described, by manipulating the rod 51, the jerk line 55 may be rendered inoperative, whereupon by manipulating the lever 37, the drum 26 may be rendered operative to reel in the drill rope 27. Or, when both the jerk line 55 and the drill rope 27 are out of commission, the lever 6a may be manipulated to connect the drum 62 to the shaft 60, thereby reeling in the slush-rope 69.
