Wn/ I H I h z W Patented Nov. 25, 1930 UNITED STATES LEE E. Manon, or NORPHLE'I, nmmnsas r CASING SUSPE'IQ'SION HEAD Application filed January 19, 192?. Serial No. 162,164.
This invention aims to provide a novel casing head whereby a pipe, generally known as the oil string, may be suspended from the upper end of the surface casing of an oil well.
It is within the province of the disclosure to improve enerally and to enhance the utility of devices of that type to which the invention appertains.
With, the above and other objects in view which will appear as the description proceeds,
the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
, In thedrawings:
Figure 1 shows in elevation, a device constructed in accordance with the invention;
Figure 2 is a longitudinal section wherein parts appear in elevation;
Figure 3 is a cross'sect'ion on the line 3-3 of Figure 1.-
The device forming the subject matter of this application includes a tubular body 1, 'provided at its upper-end with an outstanding flange 2. In the lower end of the tubula'r body 1 there is a cylindrical bore 3. The
body 1 has a conical bore 4' located above the cylindrical bore 3. At the place where the bores 3 and 4 join, there is an internal shoulder 5 in the body 1. The lower end of the body 1 is externally threaded, as shown at 6, so that it may be mounted in the upper end of a surface casing 25. The body 1 has any desired number of transverse openings 7 these openings 7, preferably, being located between the upper end of the threading shown at 6 and the shoulder 5.
I The pipe or oil string that is to be connected with the upper end of the surface casing 25 is marked by the numeral 8. The pipe 8 exbody 1. A plurality of yieldable packing members 9, such as'rings, are superposed on each other, and are disposed about the pipe 8, the lowermost of the packing memers 9 resting on the shoulder 5. The uppermost packtends downwardly through the bore 3 of the ing member 9 is engaged'by a foot piece 10, preferably a metal ring. The foot piece 10 is engaged by a plurality of pressure members 11, disposed about the pipe 8 and curved to conform to the pipe. The outer surfaces of the pressure members 11 are smooth and these surfaces cooperate with the conical bore 4 of the body 1, the pressure members 11 being wedge-shaped in longitudinal section. The pressure members 11 are supplied at their inner edges with transverse teeth 12 adapted to engage the pipe 8. At their upper ends, the pressure members 11 have outstanding arms 14, overhanging the flange 2 of the body 1. Fastening. devices are supplied, the fastening devices preferably being in the form. of screws 15 mounted to rotate in the arms 14 of the pressure members, the screws 15 being threaded into the fiange 2 of the body 1, and the heads of thescrews engaging the arms 14 of the pressuremembers.
By threading down the screws 15, the pressure members 11 will be moved downwardly, the lower ends of the pressure members bearing on the foot piece 10, and the foot piece 10 compacting the packings 9 about the pipe 8 to secure a fluid-tight joint between the oil string 8 and the member 1, the gas and water pressure being relieved through the openings 7 instead of passing upwardly about the-E pipe 8. The pipe 8 often is of great lengthgiflj and by suspending the pipe 8 as shown, the slack is taken out of it. The teeth 12 on the pressure members 11, cooperating with the pipe 8, tend to hold the pressure members in the position to which they may have been advanced.
What is claimed is A device of the class described, characterized by the provision of individually adjustable and individually, removable pressure members, said device comprising a body having an internal shoulder, a packing means in the body and engaging the shoulder, the. aforesaid pressure members being v wedgeshaped, each pressure'member operating independently of the other pressure members, the pressure members, engaging the packing means and being movable longitudinally within the body, the pressure members having separate outstanding arms overhanging the outer surface of one end of the body, whereby all of the pressure members may be removed, leaving the body in place, and an individually operable fastening device pass ing through and engaging each of the outstanding arms of the pressure members, the fastening devices being mounted adjustably at their inner ends in said end of the body, whereby each pressure member may be removed independently of the others while pressure is upon said other pressure members.
In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
