SPECIFICATION forming part of Letters Patent No. 499,045, dated June 6, 1893.

Application filed October 29, 1892. Serial No. 450,363. (No model.)

To all whom it may concern.-

Be it known that l, SOLOMON R. SHEAKLEY, of Bradford, in the county of McKean and Stateof Pennsylvania, have invented certain new and useful Improvements in Oil-Well Rigs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in oil well rigs; and it consists in the novel construct-ion and arrangement of the parts of the derrick and operating mechanisms as will be fully described hereinafter and more especially referred to in the claims.

The object of my invention is to build arig so as to accommodate within the derrick proper all the mechanical means by which wells of the description named are drilled and operated. This is accomplished by combining with the ordinary derrick a suitable platform and suitable blocks upon the floor of the derrick for supporting the engine, and by constructing in a simple and substantial man ner a platform upon one of a series of vertically arranged girts, on which platform the band wheel and bull rope pulley are mounted.

A further object of my invention is to construct a new and improved cross head for the pitman which actuates the drill or pump as the case may be.

Referring to the accompanying drawings- Figure 1 is a perspective view of my improved derrick, or rather of the lower portion of the same. Fig. 2 is a vertical cross sectional view of the derrick. Fig. 3 is a detached view of the band wheel, the bull rope pulley and their supporting shaft. Fig. lis a view of the cross head and guide therefor detached. Fig. 5 is a sectional view of the same. Fig. 6 is a rear elevation of the slide-way and cross head. Fig. 7 is an elevation of a portion of the derrick showing the cross heads secured between rods \V in solid lines, and in its operative position in dotted lines.

The derrick in which I make my novel arrangement of machinery and the several operating parts essential to the successful operation of a well is in construction very similar to the ordinary derrick, with the exception that its lower portion is constructed of heavier material than that usually employed, so that a strong foundation is provided for the elevated frame A, which rests on one of a series of girts or tiers B, two or more of the latter being arranged in vertical succession so that the vertical position of the frame A, may be varied to suit the workingof the mechanical contrivances presently to be mentioned.

Suitably journaled in the frame A, is the shaft 0, and mounted thereon is the band wheel D, connected with the engine E, by the belt F. The engine is substantially mounted as shown on the floor of the derrick. Loosely mounted on the shaft 0, is the peripherally grooved pulley G, which may be made rigid with shaft so as to revolve with it by the movable clutch H, of ordinary construction'which is operated by the depending lever I, extending within reach of the operator. An endless rope encircles this pulley which extends to the bull wheel J, suitably mounted on one side of the derrick as shown. Through the medium of the belt F, and rope I, the said bull wheel is revolved by the engine and drill rods and other tools are thereby easily elevated into position through the medium of the rope and tackle J, which is actuated by the drum of the said bull wheel.

Arranged within the derrick are the upwardly converging supports L, and secured thereto are the parallel strips M. Confined between these strips is the vertical guide way N, upon which moves the cross head 0, which is pivotally connected by means of the vertically extending rod P, to the crank Q, on the end of the shaft C. The said shaft being revolved through its connection with the engine the said rod P, is actuated and the head 0, reciprocated vertically. The guide N, is slotted longitudinally and extending therein from the head 0, is the tongue E. This tongue is the same thickness as the guide N, and projecting from the same are the headed projections S.

T, designates a plate having openings U, whereby the plate may be fitted over the said projections and made to bear against the guide N, and as the said openings are constructed with ofisets the plate may be pushed down, the said offsets fitting over the projections too but behind the heads thereof so that the plate is securely'held in place. As a further precaution against the same becoming displaced a set screw U, is provided which penetrates the plate and extends into the tongue R, thus binding together the latter and the said plate.

in a mostsecure manner; From this described construction it will be understood that while the head 0, has a free vertical movementryet it is quite impossible for the same to become displaced on the guide N. The head is provided with: the outwardly projecting earsV,

having grooved upper faces for accommodating any suitable devicefor grasping the inplace by-the capsVC- cates in a: vertical line oration below-so that The head'O; recipro the-same would be in theway off the. rope and tackle J While the latter"is'aoperatingover thewell'. To obviatethis trouble two rods W, are-arrangedparal lelwit'hteach-ot'her and heldbetween the cross strips ,M; These rods are inclined at. a" suitable aangle TSOELSt'O accommodate the head 0; as thelatter is swung shown@ in: Fig. 7'; Theprojecting tongue'of guideFN; angle or- 'inclination the the latter.
