UNITED STATES WILLIAM GLARKSON, J R., OF CORSICANA, TEXAS.
JACK-POST STRUCTURE FOR OIL-WELL RIGS.
Application filed December 6, 1926. Serial No. 153,030.
This invention relates to new and useful improvements in jack post structures for 011 well rigs.
The object of the invention is to provide a structure that will be more substantial, efficient and simple and which will not be likely to loosen or wobble.
A further object of the invention is to pro-- vide a cap and brace block together with braces, whereby a superior brace and superstructure is had and a simple assembly is produced.
A construction designed to carry out the invention will be hereinafter described, together with other features of the invention.
The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:
Fig. 1 is a side elevation of a jack post structure built in accordance with my invention 2 is a front elevation of the same,
Fig. 3 is an enlarged vertical sectional view through one of the posts, and
Fig. a is a detail of the brace bracket.
In the drawings the numeral designates a. concrete base or foundation built in accordance with oil field practice and which may be a continuation of the rig iron base on which the Sampson post is mounted. On this base I mount a pair of base plates 11 and 12 respectively, which are spaced apart transversely of said base. Each base plate comprises a circular socket 13, as is shown in Fig. 3, and a flange lt for receiving foot bolts 15 imbedded in the concrete base. The flange is fastened by nuts 16 screwed onto said bolts.
A pair of posts 17 and 18 respectively have their lower ends stepped in the sockets 13 of the base plates. These posts are preferably tubular and may be formed of salvaged pipe; however, the invention is not to be limited to the exact shape of the posts. Each post has an overhanging cap 19 supported on its upper end, and each cap is provided with a central boss 20 made to snugly fit in the upper end of the post, whereby the cap is held against lateral displacement. On each cap is mounted abrace block 21. Each block has a central depending lug 22 fitting in a sump 23 formed in the center of the cap 20 and is also provided in its under side with a transverse recess 24 for receiving said cap.
In order to brace the posts, each block 21 is formed at its opposite ends with hook lugs 25. Each base plate has a pair of housed cars 26 on its front and rear ends. Vertical tie rods 27 have their lower ends extending through the ears 26 and their upper ends extending through the lugs 25. Nuts 28 are screw-threaded on the lower ends of the rods and nuts 29 screw-threaded on the upper ends of said rods, engaging the lugs 25, thus fastening the block 2-1 on its cap.
Each block. at its center, has a trans verse bearing boss 30 concaved to receive a jack shaft 31. On each block is mounted a top or cover member 32 having an arched bearing portion 33 fitting over the shaft 31 and provided with depending lugs 34- straddling the boss 30. The member 82 has openings through which the rods 27 pass and nuts screwed on the extreme upper ends of said rods hold the cover member in place, as is shown in detail in Fig. 8. The exact construction and arrangement of the brace block and the cover member are subject to variation within the scope of the invention, the important feature being the hook lugs 25 and the tie rods.
For bracing the structure, I provide brace rods 36 having eyes 37 at their upper ends and including turn-buckles 38. The eyes of the rods are engaged over the lugs before the rods 27 are placed in position, said lugs being suitably shaped to receive the eyes. The rods 36 are provided with smaller eyes 39 at their lower ends, which are engaged in the eyes of anchors 40 imbedded in the concrete base 10. By means of the turn buckles 38, the brace rods may be placed under tension and thus adjusted in conjunction with the rods 27 will hold the posts 17 and 18 in proper vertical position. The cover plate 32 may be removed at any time without disturbing the braces or the tie rods.
The shaft 31 has a pair ofthrust collars 41 fastened thereon and engaging thev inner sides of the brace blocks and their covers, whereby said shaft is held against longitudinal displacement and the super-structures on the posts, together with the posts, are held in spaced relation. A crank arm 42 is fastened on one end of the shaft 31. A brace member is fastened to the post 18 and comprises a brace 43 and tension rod 44, to-
gether With a bracket and a foot member 46. The brace 43 has its ends seated in the bracket and foot member, and the rod is fastened to said parts by nuts 47. The bracket is secured to the side of the postbybolts 48 and the foot member is fastened by foot bolts 49.
It Will be seen that by reason of the side brace member and the collars 41, all side thrust of the structure will be absorbed'and the posts adequately braced. This arrangement leaves the post 17 free from side bracing, which would interfere with the revolution of the crank arm 42. 7
Various changes in the size and shape of the different parts, as Well as modifications and alterations, may be made Within the scope of the appended claims.
What I claim, is:
1. In a jack post structure, the combination of a base member having a socket and opposite housed ears, a post having its lower end fitting in the socket of the base member, a cap mounted on the post, a brace'block mounted on the cap and held against displacement thereon, said block having a bearing boss at its center, hook ears provided on each side of the block, connecting rods having their ends secured to the housed ears of the base member and the hook ears of the block, and braces having their upper ends hooked over the hook ears of the block.
2. In a jack post structure, the combination of a base member, a post mounted on said base member, a cap mounted on the post, a brace block mounted on the cap and having a bearingboss at its center. hook ears on each side of the block, connecting rods having their lower ends secured to the base member and their upper ends passing through the hook ears, and braces having eyes at their upper ends engaged over the hook ears.
3. In a jack post structure, the combination of a base member, a post mounted on said base member, a cap mounted on the post, a brace block mounted on the cap and having a bearing boss at its center, hook ears on each: sideot' the block, connecting rods having their lower ends secured to the base member and their upper ends passing through the hook ears, braces having eyes at their upper ends engaged over the hook ears, a top bearing member fitting on the block, and bolts on each side of the hook ears securing the bearing member on the block, the upper ends of the connecting rods and the top bearing member preventing displacement of the eyes of the braces.
4:. In a jack post structure, the combination of a pair of spaced base members, a pair of tubular posts having their lower ends confined on the members, caps mounted on the posts and having portions depending thereinto, brace blocks mounted on the caps and held against lateral displacement thereon, hearing bosses at the centers of the blocks, hook ears on each side of the blocks, brace rods having eyes engaged over said ears, vertical connecting rods having their lower ends secured to the base members Within the margins of the same and having their upper ends secured in the hook ears, top bearing members fastened on the blocks, a jack shaft mounted on the bosses of the blocks and confined against longitudinal dis placement, and a side brace extending from one of the posts.
In testimony whereof I affix my signature.
