Application filed April 12, 1924. Serial No. 706,158.

To all whomz't may concern Be it known that I, LOVIAS FAIRY FRASER, a citizen of the United States, residing at Drumright, in the county of Greek and State of Oklahoma, have invented new and useful Improvements in Jack-Post Bearings, of which the following is a. specification.

This invention relates to jack posts, commonly used in oil fields, and contemplates a structure which eliminates the use of many timbers which are used as a base or foundation for the posts in present day use, and thus provide a post that is more durable, cheaper to install, and one which can be quickly and conveniently disassembled and used again should a well be abandoned.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a view in elevation of the invention.

Figure 2 is a top plan view.

Figure 3 is a sectional view taken on the line 38 of Figure 1.

Figure 4L is a sectional view taken on the line 4cl of Figure 1.

Figure 5 is an end elevation of one part of the bearing.

Figure 6 is a similar view of the other part of the bearing.

Referring to the drawings in detail, 10 represents an elongated base member which is adapted to be bolted or otherwise suitably secured to a concrete foundation 11. Rising centrally from this base is a solid tubular portion 12 which is adapted to be received by the adjacent end of a metallic casing 13 which constitutes the post. It will be noted upon inspection of Figure 1 that the tubular portion 12 is slightly reduced to form a shoulder 14 at its point of juncture with the base, that the lower end of the post reposes on this shoulder.

Supported upon the post is a. two part bearing, the respective parts of which are illustrated in Figures 5 and 6, the lower part 15- which. is formed with a centrally. de-. pressed portion 16: as shown.

of. the bearing includingan elongated-- platei Depending-1 from this depressed. portion is a tubulaia.

member 17"sim'ilar to the tubular portion 12} above referred to, and which tubular member 17 is adapted to be received by the adjacent end of the post or casing 13. The tubular member is formed to provide a shoulder 18 which rests upon the upper end of the post as clearly shown in Figure 4. The upper part of the bearing consists of an elongated plate 19 which is considerably shorter than the plate 15 of the lower part of the bearing, and is formed with a centrally bulged portion 20 as illustrated in Figure 1. This portion of the bearing is also formed with a reinforcing rib 21 which is arranged longitudinally of the bulged portion 20. The upper part of the bearing reposes upon the lower part, and these parts are secured together by fastening elements 22 which are adapted to pass through aligned openings. In addition to these fastening elements 22 the respective parts of the bearings are held associated by stay rods 23 passed through aligned openings adjacent the corners of the bearing and having their lower ends embedded in the concrete foundation. Rising from the opposed ends of the plate 15 are spaced a-pertured lugs 24, these lugs being obliquely disposed and closely associated to receive therebetween stay rods 25 which extend from the ends of the lower part of the bearing in the direction of the ground where they are secured at points remote from the bearing proper. The rods 25 are held positioned between the lugs 24 by means of nuts 26. It is to be understood that the various parts of the invention can be constructed from any suitable material and also vary in size without departing from the spirit of the invention. Furthermore, it

is manifest that the construction is a durable one requiring practically no upkeep as there is nothing to wear, and that the component parts of the invention can be quickly and conveniently assembled and disassembled as the occasion may require.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall Within the scope of what is claimed.-

Having thus described the invention, I claim:

In a post of the character described, a base including a tubular portion rising centrally therefrom, an annular shoulder formed on the tubular portion, a casing adapted to be fitted over said tubular portion and havingtits lower end reposing .on said shoulder, aztwo partbearing arranged upon saidlcasing, one part of the bearing being relatively long and including'a tubular portion depending therefrom and adapted to be received by the adjacent end of the easing, a shoulder formed on said tubular portion, to bear against said casing, means for securing the respective parts of the bearing together, stay rods passed through aligned openings in both parts of the bearing, spaced apertured lugs rising from the opposed ends of the first mentioned part of the bearing, stay rods having their adjacent ends adapted to be positioned between said lugs, and a reinforcing rib extendedacross the second mentioned part ofsaid bearing.

In testimony whereof I aflix my signature.

I LOVIAS FAIRY FRASER.
