7' CLAMP.

Application filed October 2 ,1924. Serial No. 741,271;

This invention has reference/to casing head clamps, and aims to provide novel means whereby a pump jack may be readily attached to a-stuffing box casinglhead.

Another-important object of the invention is to provide a device of this character in-o eluding a three point suspension for securely gripping 'the'bowl of the [casing head.

A still further object of theinventi'on is m to provide a device of this character which may be readilyand easily scuredtoa casing head, elimlnatmg the necessity of making extensive alterations in thecasinghead or clamp, to position the device.

v view which will appear as the description I proceeds, the invention resides in the coinbination and arrangement" of parts and in the details of construction scribed and claimed, it

[that changes in the-precise the invention herein within the scope of what is claimed, Without departing from the spirit of the invention. I Referring to the drawing: 7 I Figure 1 is a side elevational view "of a clamp constructed in accordance with :the invention, showing the clamp positioned on a casing head. V j a Figure 2 is a plan View of thevclamp.

Figure 3 is an end elevationalview therebeing understood embodiment of of. p V V vReferring to the drawing in detail, 'the clamp includes sections 5 and 6 respectively,

'35 the sections being formed with laterallyex= tended ears 7 which are formed with open- --ings to accommodate the connecting bolts 8 that extend through aligning openings, to

secure the sections together. I

curved as at 9 to provide a surfaceto'com form to the curvature of a 'ca'singhead, so that the sections may be moved into close engagement with the casing head'to accomplish the purpose of the invention.

With the foregoing and other objects in hereinafter, de- 7 disclosed, may be made 7 construction of the clamp issuc'h that a Each of the sections has its inner surface- Extending upwardly each section "I Y f and disposed at a point adjacent to the ceni tral portion of the curved surface thereof, l

i's'a finger 10 adapted to engage the casing i head to vwhich the clamp is secured. Deol" pending from theunder side of each section, are flanges 11 which cooperate 'with'the fin gers v9 for gripping the casing head to which the casing head is secured, therebyprovid-' ing a three point clamping construction.

The: bolts 8 are providedwith-threaded portions 12 that accommodatethe nuts13 so that the clamping sections may be secured; in position on a casing head. E te11ding from'one-of 'the sections are spaced ears 14 whichare also formed with openings tolaccommodate a bolt so that a'jack brace may be secured thereto;

As illustrated by Figure 1, he clamp'is shown aspositi'oned on a casing head, thee-3 casing head being indicated at-'15. From the foregoing it will be obvious that due to this construction, the casing head may besecurelyheldinto position. and the 4 close-fit will be insured betweenthe well casing head and stuffing box l m Y A casing head clamp" including separable Y sections having curved cooperating edges adapted to fit around" the curved surface of" a caslng head, said sectionsihavingupward- 1 ly extended integral fingers arranged .adjacent tothe curved surfaces to engage the 'straightjportion of a casing head, lateral apertured cars, bolts extending through the ears for securing the clamp to. a casing head,

upwardly extended ears forming a part f one' of the sections and having openings to I receive a bolt for supporting a pump, jack.

In testimony that I claim the foregoing as my own, ture. I
