STANDARD-RIG: CONSTRUCTION.

Application led January T0 all 'whom t may concern.'

Be it known that I, LLOYD E. LEWIS, a citizen of the United States, residing at Shreveport, Louisiana, have invented a certain new and useful Improvement in Standard-Rig Constructions, of which the following is a specification,

My invention relates to standard rig equipment for well operations.

I have Jfound that the usual standard rig is subject to many objections because of deects in construction. The wooden structure ordinarily employed to support the operating means will warp under strain and 1t also quickly deteriorates and breaks under wear and decay in adverse weather conditions. Thus the belts or chains are thrown out of line and the posts are subject to breakage under side strains set up where the base is thrown out of alignment. Attempts have been made to form a more durable and lasting structure but the expense of heavier wooden construction is great, and the diiiiculty of keeping the parts in al1gnment is not overcome.

I have, as an object of my invention, to construct a irmand substantial hase of concrete which will be of one integral piece and hence not subject to be moved out of alignment. To form the base of concrete it has been necessary to modify the remaining` structure in certain essential respects as will appear.

I also desire to construct the body of the supporting structure of material easily obtained about the usual oil well operating equipment.

Certain other objects and the means by which they are accomplished will more clearly appear from the description which follows.

Referring to the drawing herewith Fig. 1 is a side elevation, certain parts being in vertical section, illustrating a standard rig employing` my invention. Fig. 2 is a vertical section of the upper end of the Samson post and walking beam. Fig. 3 is a horizontal section on the plane 3 3 of. Fig. 1, Like numerals of reference are employed to designate like parts in all the views.

In adapting the standard construction for manufacturing it of concrete in one unitary structure, it is necessary that certain essential changes in the construction of the rig be made. The usual standard rig which 10, 1925. Serial No. 1,692.

may be employed either in drilling by the reciprocating method, or for pumping the well after it has been drilled. It includes a Samson post 7 with a walking beam 2 supported on the Samson post for a rocking motion. It also involves the use of two spaced jack posts upon which is journaled a shaft to which the usual rig irons are se` cured. I contemplate uniting all of these parts of the rig in as nearly integral construction as possible, and also desire to form both the jack posts and the Samson post of pipe of a standard construction such as may be found about the usual oil well.

In carrying out my invention I form a transverse base 1 for the jack post. This base is of solid concrete, and has thereon spaced blocks 2 elevated somewhat above the base for supporting the jack posts 3.

To more firmly anchor the base 1, and to prevent any change in position with the base, I construct two longitudinal cross members t and 5 projecting from the base 1 in opposite directions. The longitudinal member 4 projects equal distances in each direction from the base. The member 5 however is extended materially beyond the member 4L upon one side to connect with a block 6 forming a support for the Samson post 7 The two longitudinal members l and 5 are reinforced b. transverse rods or bars 8 and 9 on each si e of the base 1 and parallel therewith. These rods are embedded in the cement and act to hold the longitudinal members in rigid alignment.

In order to construct the jack post 3 of ordinary pipe construction, I have devised a base plate 10. This plate has central openings therein to receive a plurality of stay bolts 11, the lower ends of which are hooked and anchored into the cement when the base is cast, and the upper ends of which are threaded at 12 to receive nuts by means of which the plate is held embedded within a seat 13 formed in the cement to receive the same. It will be noted that the plate may be removed if necessary without inter fering with the concrete base in which it is seated. The plate 10 is formed with a central circular boss 14 thereon adapted to fit within the tubular posts 3.

The posts 3 may be of the usual height suitable for ordinary well operations, and are adapted to be fitted within and secured to the lower bearing plates 15. Each bearing plate is of the usual construction having a bearing recess 16 therein to receive the cross shaft 17 upon which the usual rig irons and crank arm are mounted. A top bearing plate 18 serves to hold the shaft firmly in position. Both bearing plates are secured together by through bolts 19, and also by rods 2O extending from said plates downwardly and secured through a C link 21 to the anchor bolts 22 embedded in the cement base. The posts and the bearing plates are, however, reinforced and braced by laterally inclined rodS 23 and 24 on each side thereof, said rods including a centrally turnbuckle 25 and a lower eyelet 2 6, secured in anchoring bolts 27 embedded in the cross members 4 and 5 at points spaced a desired distance away from the jack posts.

The Samson post 7 is secured upon the supporting block 6 in a manner similar to that employed in connection with lthe jack posts. There is a base plate 10 embedded in the upper face of the block and anchored in position by means of stay bolts 28 as previously described, the upper circular boss 14 on said plate lits within the central opening of the tubular post 1. The post is anchored in position, however, by means of rods 29 connected at their upper ends to a diametrical bar 30 passing through an opening in said Samson post. The lower end of said rods are detachably secured to the stay bolts 3l, embedded in the cement as clearly shown in Fig. 1.

The Samson post is also braced by means of the inclined brace bars 32, which are fitted at their upper ends within a notch or recess 33 formed in the side of the Samson post and the lower ends of which are seated within notches or recesses 34 formed in the base 5. There is also a rod 36 connected at its upper end to the Samson post, and at its lower end to stay bolts 37 anchored in the base member 5. A turnbuckle 38 in said rod 36 allows the tension thereon to be adjusted as occasion arises. The Samson post is formed with ahead 39 thereon which is formed of two similar side members spaced apart by means of a. plate 40 and adapted to fit at their lower ends within the upper end of the Samson post. They are securely held in position in said post by means of transverse bolts 41 extending diametrically through said Samson post and the three parts comprising the bearing member. The upper ends of the two parts 39 are formed to receive the shaft 42 and to lallow a rocking movement of said shaft It is contemplated that the ends 44 of the' walking beam will be positioned over the jack posts in such manner as to connect with the crank arm on the shaft 17 for operation in the usual manner, and that the Opposite end of said walking beam may be connected to the drilling apparatus or the pump rod in the customary manner.

The advantages of this type of construction are numerous. It serves to form a solid unitary construction out of material which may be readily assembled and erected within the oil fields` t supplies a firm base which will not get out of alignment and will not deteriorate in use. The structure is essentially a cheap and economical one, and its construction simple and rugged.l It is necessary however to have certain special parts which have been described forming eatures of novelty which are set forth in the claims.

While I have shown a concrete embodiment of,my invention, I wish it understood that certain changes may be made therein coming within the scope of the claims, and l do not wish to be confined to the eXact details above described.

What I claim as new and desi-re to protect by Letters Patentis:
