ALEXANDER FRANCE, 0F MARS, PENNSYLVANIA.
BRICK STRUCTURE.
Application filed August 17, 1922. Serial No. 582,526.
To all whom it: may concern Be it known that I, ALEXANDER FRANCE, residing at. Mars, in the county of Butler and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful improvements in Derrick Structures, of which improvements the following is a specification.
My invention relates to derrick structure, and is applicable particularly to the building of derricks for the drilling of deep wells, such as oil and gas wells. The objects of my improvements are security combined with simplicity of structure and consequent facility in erection.
The invention is illustrated in the accompanying drawings, in which Fig. I is a view in side elevation of a derrick embodying the invention; Fig. H is a fragmentary View in horizontal section and to larger scale, through one of the corners of the derrick of Fig. 1; Figs. HI and TV are views similar to Fig. ll illustrating permissible variations in details of structure; Figs. V "and VT are views corresponding to Figs. I and TI, and they illustrate the applicability of the invention to derricks built wholly of pipe,
Referring first to Figs. T and T1, the derrick there shown consists essentially of the corner posts 1, the cap beams 2, girds 3, and braces 4. The corner osts are in this case formed of wood, an specifically of planks, laid and joined in'the arrangement clearly shown in Fig. 11. The girds and braces are formed of metal, ordinarily of steel pipe, cut to proper length, with ends forged and pierced, to permit of bolting to the corner posts, in the manner indicated in Fig. IT. My invention is found in the bifurcated form to which the ends of the girds are forged, as shown in Fig. I, each gird end being provided with two bolt holes, and in the assembly of such bifurcated-ended girds with the other parts in the manner shown. The girds are applied to the corner posts with'the bifurcated ends of the girds disposed longitudinally upon the corner posts, and through the two bifurcations are bolted the upper and the lower braces.
These features are to be noted of the union and anchorage so brought about: first, while special anchoring members, secured to the corner post and affording anchorage for girds and braces are not forbidden, none is required. Tnstead, the girds and braces may be bolted directly to the posts. This is a feature of simplicity. Second, while, as in the standardized form of.derrick, three transverse members are secured to the vertical member at substantially one spot, these members are not bolted by one bolt, to the vertical member, but are bolted two by two by two bolts. This is a feature of combined simplicity and security. Third, the gird in consequence of its extended form and plurality of bolt holes becomes itself in some degree a truss, thus making for greater rigidity of structure.
Tn connection with the point last noted, 1 direct particular attention to the uppermost brace members 49 of the derrick structure illustrated in Fig. I. These at their upper ends are bifurcated, in like manner with the gird members throughout, and are anchored through'one bifurcation to the corner post and through the other to the top beam of the derrick. This is an added feature of structural novelty, and it too, as will be perceived, makes for rigidity.
Figs. TH and TV indicate that in the assembly various arrangements of the bolted parts may be had: the girds and braces, shown in Fig. H to be bolted to the corner posts on the inside, may, if desired, be bolted on the outside (Fig. Ill, the lower joint) or, girds may be bolted on the'inside and braces on the outside (Fig. TV) or, again, the bifurcated end of the gird may be so particularly shaped as to lie, one bifurcation on the inside, the other on the outside, of the corner post (Fig. HT, the upper joint, where the gird is designated 3 Figs. V and VT show application of the invention to a derrick whose corner posts are formed of pipe. No detailed explanation is necessary. The drawings show the bolting made directly through the pipe 1 which constitutes the corner posts. Of course the bolting may be through coupling members which unite pipe lengths in such a structure, or through iian es formed upon such coupling members. T ese features are known to the art, and require no more than passing mention.
As is now commonly the practice, the parts of the derrick are made up in the shop and are shipped in knocked down condition to the field, for erection there. 'At the same time the structure is in its parts so sim 1e that replacements may readily be ma e in a blacksmiths shop in the field.
I claim as my invention:
1. A derrick structure formed by the combination of corner posts girds and braces, the girds being formed with terminal truss forming bifurcations, and each glrd' at each end being assembled with two braces and the Whole secured to the corner post by a bolt" through each bifurcation of the gird and through one of the two brace members.
bination of corner posts girds braces and 2. A derrick structure formed by the comcap beams, the girds being formed with terminal trussforming bifurcations and being secured with the braces through such bifurcations to the corner posts, and the uppermost braces being formed at their upper endswith truss-formin bifurcations and being secured throu h suc bifurcations to corner posts and cap eams.
In testimony whereof I have hereunto set my hand.
ALEXANDER FRANCE.
