G. P. SLATER.
DERRICK. APPLICATION man Aue.4. 1920.
Patented Oct. 18,- 1921.
UNITED STATES PATENT OFFICE.
GUY 1. SLATER, OF TULSA, OKLAHOMA.
I DERRICK.
Specification of Letters Patent.
Patented Oct. 18, 1921.
Application filed August 4, 1920. Serial No. 401,106.
Ta all whom it may concern Be it known that I, GUY P. SLATER, a citizen of the United States of America, and resident of Tulsa, in the county of Tulsa and State of Oklah new removed as stated.
With partsto be hereinafter more fully set forth and claimed.
In describing the invention in detail, ref
several views, and in wlnch- Figure '1 illustrates a a fragment of the derrick frame showing the invention applied tiereto; Fig. 2 illustrates an enlarged detail perspective view of one of the joints; and I lfig. 3 illustrates a longitudinal sectional view thereof. I
Fig. 4: illustrates a sectionalview embodying aslight modification.
In these drawings 5 and 10 represent corner legs of extension, the'same being practically duplicated except as to their relation to each other and this is changed owin that the legs converge toward As the joints between any two of the legs are the same regardless of which section is described, one of the joints and parts relating to it will be described and the description will be understood as applying to all of such joints. 4
Corner plates 11 are bent so that the sides ire practically at right angles to each other view in elevation of t and each side has apertures 12 and 13 intended to receive the ends of a brace or guy wires 14.
The upper end of one post 6 and the lower end of one post 8 are connected together by a tubular,splicing member 15 the external diameter of which is equal to the internal diameter of the said telescope on member, ing member and a leg. The plate 11 extends these legs by U-bolt s 17 having nuts 18 applied at their outer ends by which the loop portions of the bolts and the angular portion of the plate are tightly bound against the legs to coiiperate with the member 15 within the legs to strengthen the structure he said structure is of greater strength at these joints than at points thereetween. The said plates are furthermore provided with U-bolts l9 embracing the girths 20, the said girths e said legs. W hen the parts are assembled and clamped together as shown in Fig. 2, the frame structure of the derrick is very strong, and as shown in Fig. 2, the girths have their ends abutting the leg sections at the joints he girths press against pper leg sections where they are connected together.
In Fig. 4 I l ments of the d relation as described in disclosures of Fig modified construction the sleeve 15 is applied externally of the leg sections 6 and 8 instead of being on the inside of those leg sections.
I claim:
1. in a derrick, terial, a splicing leg sections holding splicing c said plate to leg sections of tubular mamember inserted in the said at their junction, means, for the splicing member in place; a plate angular in plan embracing sections, means for clamping the the leg sections, girths having their Ililll and ends abutting the legs at their junction,
' the means carried by the plate for holding girths.
2. In a derrick structure, superimposed leg sections joined together, a member inserted in. the said leg sections and spanning the joint between the said leg sections, late having its sides at angles to each other, the said plate embracing the leg sections at their junction, U-shaped bolts embracing the said sections and extending through the plate, means for securing the bolts to the plate, girths having their ends abutting the leg sections at their joint, and means for holding the said girths in assembled relation to the plate.
1 ,seasaa 3. In a derrick structure, superimposed leg sections joined together, a member inserted in the said leg sections and spanning the joint between the said leg sections, a plate having its sides at angles to each other, the said plate embracing-the leg sections at their junction, U-shaped bolts embracing the and extending through the said sections plate, means for securing the' bolts to the plate, girths having their ends abutting the leg sections at their joint, the said plate having apertures for the anchorage of bracerods, and means for holding the said girths in assembled relation to the plate.
GUY P. SLATER.
