JACK-POST CONSTRUCTION.

Application filed October 30,1925. Serial No. 65 ,808.

' This invention relates to improvements .in

7 jack post construction for use upon and in conjunction with oil well rigs and .derricks and which contemplates the substitution of metal parts for wooden parts now used in the construction of rigs, the wooden parts being verycostly and hard to obtain whereas the metallic structures are stronger and last longer and are capable of withstanding rigorous service better. V

More specifically stated the post being constructed for lengths of tubing suitably anchored and including mountings upon their upper ends journaling a walking beam thereon.

lVith the above and other objects in view,

the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a side elevation of my invention when set up in operative position.

Figure 2 is a fragmentary elevation of the post.

Figure 3-is a side elevation means for a drum well.

Figure 4 is a fragmentary top plan view of the supporting means for the drum well.

Referring to the drawings in detail, whereof supporting in like characters of reference denote corresponding parts, the reference character 10 indicates pairs of companion pipes having flanged end collars 11 securedto their lower ends anchored to supporting blocks 12, preferably formed of cement. The remaining ends of the pipes 10 extend inwardly one toward the other and terminate in flattened end portions 13. The outer sides of the flattened end portions having side strips or plates 14 secured thereto through the instrumentality of bolts 15 having spacing thimbles 16 arranged thereupon. 'The upper free ends or edges of the spacing strips or plates 14 have inwardly extending end portions 17 extended over the upper free ends of the flattened end portions 13.

Belts or lengths of strap iron 18 form loops 19 upon their opposite ends, encircling the adjacent pairs of pipes 10 forming a strengthening medium intermediate their lengths to overcome vibration incident to crystallization and to prevent any inward bending thereof incident to the manner; in

bearings for the wheel drum 27.

which the invention is used. A walking beam 20 1s mounted for rocking movement intermediate its length upon the upper free ends of the flattened end portions 13 of the pipes 10. A connecting rod or arm 21- having a yoke 22 arranged upon its upper end receives the. outer free end of the walking beam 20 therein. A removably'secured plate 23 carried upon the upper side of this end of the walking beam 20 is adapted for engagement with the looped end of the yoke 22 for securing the latterthereonJ] The opposite end of the connecting rod or arm.- 21 having a longitudinally disposed elongated slot 2% therein for the reception of a pivot pin 25 extending outwardly from an arm '26 provided upon the outer endof a shaft, not shown, carried by a well drum 27 including a belt 28 trained under and over the same from a suitable source of momentum or power, not shown.

In order to provide a suitable sup ort for the wheel drum 27 I provide a pair 0 spaced parallel angle bars 29 also being anchored to cement blocks 30 or the like. A substanstantially inverted U-shaped plate 31 has the extremities of the legs thereof secured to the base or seat upon which the bearings for the wheel drum shaft may be supported.

To overcome vibratory movement of the well drum 27 incident to the rotation thereof I provide spacedv parallel plates 32 having their upper'free ends secured-to the innersides of the plate 31' while their. outer ends extending in obliquely disposed relation with respect to the. vertical centers thereof and secured to the inner sides of the angle bars 29. The clevis 33 being also correspondingly' associated at the latter juncture for association with one end of a turn-buckle rod 34 having its opposite end secured to the Brace arms 35 having their upper ends secured to the outer'sides and intermediate the lengths of the arms-32 extending inwardly with respect thereto and within depressedportions 36 formed in the outer sides thereofwhile Manifestly from the foregoing description 7 Y and accompanying drawings, a metallic structure having been defined capable of functioning and strengthening in the manner as clearly described and illustrated ireplacing Wooden parts for iron and all of which being so mounted to overcome vibration incident to the overcoming of crystallization and in fact providing supporting means for Well rigs as may properly replace such rigs now in use constructed of costly Wooden parts. I r

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having thus described the invention, what 15 end portions, plate members carried by the 20 flattened portions having their upper edges bent over the extremities thereof, bolt members passed through the flattened end portions of the sections and plates, spacing thimbles carried by the bolts and a Walking 25 beam fulcrumed upon the seat defined.

In testimony whereof I afiix my signature.

ROLAND o. RUMBAUGH.
