DERRICK.

Specification of Letters Patent.

Patented June-8, 1215.

Application led June 29, 1914. Serial No. 847,896.

T0 aZZ 'whom it may conce/m: l

Be it known that I, HENRY AUCHU, a citizen of the United States, residing 'at Emporium, county of Cameron, and Stateof Pennsylvania, have invented certain new and useful Improvements in Derricks, of which the following is a specification.

This invention relates to derricks.

In drilling operations in the oil regions, the common practice is to erect a wooden derrick. These derricks become permanent structures, soon go to pieces, and prove eX- pensive if the drilling operation is unsuccessful as they are not adapted to be taken apart and used at another location. The success ofan oil well drilling operation can never be foretold and the cost of the derrick is lost if oil or gas is not struck.

My object is to provide an .improved knock-down fire-proof metal der-rick for use in oil well drilling operations and which will belof such construction that it may be readily erected or taken down and moved from lace to place if its use elsewhere is desired, thereby saving the expense of erecting a new derrivck when a new well is driven or an old well is to be cleaned, or any operation in connection with a well is to be carried on where the use of a derrick is necessary.

In carrying out the invention, I provide standards or uprights composed of telescopic sections which can be drawn out or collapsed, and improved means for holding the sections in extended relation, subject totelescoping when desired; as fully set forth hereinafter.

In the accompanying drawings: Figure 1 is a perspective of the complete derrick; Fig. 2, a detail perspective showing the iirst step in the erection of the derrick; Fig. 3, a similar view showing the derrick partially erected and illustrating how the telescopic standards or uprights are drawn out as the structure is built; Figs. 4 and 5, detail views of one of the corner clamps for connecting the transverse braces to the uprights orstandards; Fig. 6,;a detail of one of the feet; Fig. 7, a detail of one of the joints or connections between the telescopic sections; Fig. 8, a similar view between the cap frame and the end of one of the uppermost standard sections; Fig. 9, a detail of the cap frame; Fig. 10, a detail showing a sectional ladder section.

The completed derriclr shown in Fig. 1 is*l erected by first arranging the parts as shown in Fig. 2 and then continuing the construction in the manner shown in Fig. 3.

Referring to Fig. 2, the base of the derrick is rectangular and is composed of pieces of angle iron 1. The four standards or uprights at the corners of the derrick are composed of telescoped tubular sections 2, 3, f and 5 which fit freely and yet not too loosely within each other, as shown in Fig. 2. The lowermost sections 2 are provided with feet 5 (Fig. 6) which are secured thereto by bolts 7. The feet 5 may be bolted or connected to any suitable foundation or set on concrete or rock piers. Outer angular clamps 8 and inner angular clamps 9 which have a substantially semi-circular part 10, are bolted to the base sections 1 by removable bolts 11, and they embrace the uprights or standards 2 and afford means for connecting them to the base sections l1. Angle iron braces 12 similar to the base sections l, andv clamps 8, 9, and bolts 11 connect the braces 12 to the uprights 2 at suitable distances apart and, similarly, this arrangement of braces and clamps is carried out in connection with the tubular sections 3, 4, to the full height of the derrick. The derrick is provided with a cap frame 13 (Fig. 9) composed of angle iron sides connected together and provided at their corners with connectors 14 which have flanges 15 overlapping the outer faces of the angle iron sections of the frame 13 and these members 14 are secured to the frame 13 by bolts 1G. They have gudgeons or lugs 17 which are receivedin the upper open ends of the tubular sections 4 and are detachably bolted thereto at 18. Preferably, no braces are inn terposed between the base sections 1 and the next higher braces 12 toy afford free open sides to the lower portion of the derrick so that the drillers and other workmen may freely pass in and out of the derrick and to provide ample room for the drilling rig.

'Between the two lower sets of braces 12 are interposed the inclined upright braces 19 which are detachably connected to the braces 12 by`y bolts 20. Interposed betweeneach successively higher set of braces 12 are the crossed braces 21 which are detachably connected to the braces 12 at 22 and are pivotally connected together at 23. These braces 21 are thus arranged so that by detaching the bolts '22, the braces may be folded together on their pivot 23, thus minimizing the number of part-s which are disconnected when the derrick is taken down.

To afford access to the top of the derrick and to provide means for the use of dthe workmen in erecting the derrick, I preferably provide a sectional laddercomposed of independent sections 24, each of which has hooks 25 at its upper end to clamp over one of the braces l2. The lower ends of the ladder sections 24 may be bolted to the braces 12, if desired, or these sections may hang freely from their hooks or clamps 25.

Each ladder section is, however, adapted for detachment independently of the remaining ladder sections, and said sections are put up or taken down, one after another, as the derrick is erected or dismantled.

Fitted into the lower ends of the tubular' sections 3 and 4, are plugs or heads 26 which are secured by bolts 2.7. When the sections are extended, as when the derrick is being erected, after a section 3, for instance, has been raised, a removable I-bolt or pin 28 is passed through suitable holes in the section 2 and another I-bolt or pin 29 through suitable holes in the lower end of the section 3 to support the upper sectio'n by the lower one in the manner shown in Fig. 7. This construction is used with succeeding sections. By merely removing the pins or bolts 28, 29, the sections can be telescoped,'when the derrick is taken down for transporta-tion to another location.

To afford means for raising the sections' 3 and 4, block and tackle 31 supported by a removable gin pole 32, may be connected, as shown in Fig. 3. The gin poles 32'are provided with a fork or clawv 33 to engage one of the cross braces 12, these poles being raised and rested on higher cross braces, as the'derrick is built up. Preferably, the derrick is built in the manner shown in Figs. 2 and 3. Referring first to Fig. 2, the base sections 1 are laid down and the clamps 8 and 9 are first secured to the standard sections 2 and then to the base sections 1. The

Y standard sections 2 have their braces 12 and 34. The remaining bolts 11 are then secured to the base sections 1 and to the clamps and braces higher up. The lower part of the derrick having been thus erected, as shown in Fig. 3, the lowest section 24 of the ladder is hooked over the braces 12 and the workmen ascend to the top of thev part of the derrick erected andr place the poles 32, as shown, and connect .the hooks of the block and tackle 31 tothe sections 3. The sections 3 may thus be elevated and secured` by the pins or bolts 28, 29, after lwhich the braces 12 and 23 may be secured. Another ladder section 24 is then placed and the workmen ascend to a higher point and use the poles 32 to draw up the sections 4. 'This operation is continued until all of the telescopic sections of the uprights or standards have. been drawn up and the braces secured, after which the cap frame 13 is placed in position, the gudgeons or lugs 17 being received the open upper ends of the `uppermost tubu lar sections and secured thereby by the pins or bolts 1S. 1V hen the derrick is toA be taken down for removal to another point, the cap frame 13 is first removed and then the uppermost sectionsl 4 are lowered, after removal of the braces and thus the derrick is taken down,sectionb'y section.

The cap frame and its connection to the. uprights constitutes the subjectanatter of a divisional application, Serial No. 13,181, filed March 9, 1915.

` Having thus described my invention, what I claim as new and desire to secure by-Letters latent, is:-

In a knock-down derrick, a standard or upright composed of telescopic sections, and

means for supporting upper sections from lower ones consisting of a plug at the lower y endof the uppersection, a removable transve'rse pin carried bythe lower section and serving as a support for said plug, anda removable pin on the upper section, said pin resting on the upper end of the lower section.

In testimony whereof, I hereunto afiix my of two witnesses.. HENRY AUCHU.
