VIILLIAM D. DESOHAMP, FORT SMITH, ARKANSAS, AND GEORGE C. JONES, OF MQALESTEB, OKLAHOMA; SAID DESOHAMP ASSIGNOR TO SAID JONES.

WELL-DRILLING DERRICK.

To all whom it may concern:

w I Be it known that we, WILLIAM D. Dn-

SCHAMP and GEORGE C. J owns, citizens of the United States, residing, respectively, at Fort Smith, in the county of Sebastian and tate of Arkansas, and McAlester, in the county of Pittsburg and State of Oklahoma, have invented certain new and useful Improvements in 'Well-Drilling Derricks, of which the following is a specification.

This invention relates to well drilling machines, and it has for its object to provide a derrick of simple and improved construction, which may be conveniently transported from place to place and which may be quickly set up for use in the desired location.

A further object of the invention is to provide a derrick of improved construction arranged to carry well drilling machinery and which may be set up close to a building or other similar construction.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it. being. however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings-Figure 1 is a top plan view of a well drilling derrick constructed in accordance with this invention, the derrick being shown equipped with a well drilling machine. Fig. 2 is a vertical sectionai view. Fig. 3 is'a detail view in elevation, reduced, of the means for supporting the outer extremity of the derrick arm.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved well drilling derrick is usually supported upon a truck-frame comprising suitably connected sills or side bars 5, 5, supported upon the axles 6, having transporting wheels 7, whereby the machine may be conveniently transported from place to place; but this supporting truck has not been shown in all the figures of the drawings in Specification of Letters Patent.

Patented Dec. 2Q, 1910.

Divided and this application filed September Serial No. 519,850.

1 order to bring out more clearly the other parts of the invention.

The base of the machine consists of a circular frame or rim 8, which has been shown as being supported upon cross bars 9, which latter may be supported upon the sills 5 of the truck. The rim or frame 8, supports a plurality of arms or spokes 10, which are mounted upon the upper surface of said frame and extend inward in the direction of the center. The rim or frame 8 also supports a plurality of rollers 11, upon which a rope-winding drum D is supported for rotation in a horizontal plane. The drum 1) is guided for rotation by a circular wheel or rim 12, which is firmly supported upon the spokes 10, and which supports an internally toothed stationary spur wheel 13.

The rope-winding drum D is provided upon its upper face with a ratchet wheel 14, the teeth of which project beyond the perimeter of the drum so as to be capable of being engaged by a clutch or locking member to be hereinafter described. The said drum is also provided adjacent to its lower edge with a plurality of outward extending ratchet teeth 15, which are suitably spaced apart and capable of being engaged by a clutch lever 16, which is pivotally supported upon one of the spokes 10, which is extended in an outward direction beyond the frame 8, so as to form a bracket 17; for the purpose of actuating the clutch lever there is provided a hand-wheel 18, upon a vertical shaft 19, supported for rotation in bearings 20, and having a crank 21, which is connected by a link 22 with one end of the clutch lever 16; the latter may thus be conveniently manipulated to place its hooked end 23 in the path of the teeth 15, for the purpose of arresting the rotation of the drum; when desired, the said clutch lever may be moved out of the path of the teeth 15 so that it will not interfere with the rotation of the drum.

A circular platform P is provided adjacent to its outer edge with a downward ex tending flange 24, whereby it is supported for rotation upon the wheel or rim 12, which latter for this purpose is provided with a step or offset 25; metallic wear-plates 26 being mounted upon the opposed faces of the flange 24 and the step 25 for the purpose of reducing the friction between the parts; it will also be observed that the flange 24 is titted within the rope-carryi11g drum 1), so 5 that the parts will be mutually guided tor rotation in an approximately horimntal plane.

It is to be understood that the parts just described are to be taken as typical of any form of well drilling machine and that these and similar parts are herein describeiil for the purpose 01? indicating the application of this derrick to use with such a machine. The platform l supports a derrick- .fraine comprising 'a plurality of inclined beams or uprights 27, the lower ends of which are firmly supported upon the platform while the up crends of said beams are bolted or otherwise secured upon a collar 28, having an annular tlanpe 2 resting upon the upper extremities of the beams 27. Fitted in the collar 28 is a ring 30 having a flange 31 that engages the tlange of the collar. Firmly bolted or otherwise secured upon the flange 31 of the ring 30 is a derrick-arm A, which has been shown as being constructed of beams 32 suitably spaced apart so as to altord bearings for the shafts 33 and 34 near the inner end of said derrick arm, and for a shaft 35, near the outer end of said arm. The shalts 33, 34, support guidewheels or pulleys 36, 37, and guioe wheels or pulleys 88, 39, are likewise supported for rotation upon the shaft 35, said pulleys being utilized for guiding respectively the drill rope and the sand line of the apparatus. The outer cfitreinity of the derrick arm A is firmly supported by suitable braces or uprights lO. it will be readily obsei ed that the ring 80 constitutes a bearing upon which the collar 28 of the derrick-frame is guided for rotation when the rotary platform is in motion during the operation of the machine.

The uprights or braces l0 which. serve to support the outer extremity of the derrick arm in when the machine is in operation, are pirotally connected at their lower ends with a cross-piece ll, adapted to rest upon the ground, while the upper ends of said uprights are connected with the derrick arm by means of a transverse bolt By this simple construction the derrick arm will be firmly supported; and the construction is such that when the machine is not in active use the parts may be disassembled by simply removingthe bolt l2, and the uprights ll) may then be folded adjacent to the cross piece ll, and said uprights and cross-piece as well as the (lQll'lCl-l-tli'Hl, which latter may be readily detached from its position on the derrick frame v may be stored upon the axles 6 between the sills 5, 5, of the truck which will support the parts also in this manner is being moved from 2. in a machine of the character described, 21 Pltll'illl'lll supported lor rotation in, an a )p oniinately horizontal plane, a derrick t' anie supported upon the platter-in, and having a l'langed collar at its upper end, a lerrick-arm ha ring a flanged ring engaging; the llallflfll collar the latter aill ordingr a bcaingr tor the ring, 'nclined uprights conll( fl0(l detaclnxbly with the derrick-arm adjaceut to the outer extremity of the latter and supporting the same in an approximately horizontal positioin and a crossbar pivotally connected with the lower extremities of the inclined uprights.

3. ln a machii'ie of the character described, a plat'lorm supported for rotation in an approximately horizontal plane a derrick trame mounted upon the platform and comprising: a plurality of inclined upwardly converging; uprights, a collar secured upon the upper ends of the uprights and having a horizontal annular flange enping the upper extremities of said no rights, a drill arm comprisinga pair oil. suitably connected spaced beams, an annular llanq'ed ring supported upon the under sides ol" the beams coi'istitutino the derrick-arm the flanged collar ot the derrick frame allording a bearing for the ring, and means for supportii'igr the outer extremity of the derrick arm to hold the latter stationary in an approxiu'iately horizontal position.
