PACKER FOR PRESSURE DRILLING HEAD Filed April 11, 1941 III IIH

Patented Aug. 29, 1944 UNITED STATES PATENT OFFICE PACKER FOR PRESSURE DRILLING HEAD Albert Pranger and Samuel Tex., assignors to The Guiberson Cor- Tex., a corporation of Dela- Dallas, poration, Dallas, ware Allen Guiberson, in,

Claims.

This application is a continuation in part of our application on Pressure drilling head, Serial No. 239,458, filed November 8, 1938, now Patent No. 2,303,090, issued November 24, 1942. The present application relates to the particular form of packer shown in said application 239,458 and in particular relates to the reinforcing means for the packer.

The invention may be better understood by referring to the attached drawing in which,

Fig. 1 is a vertical view principally in crossforming a continuous non-expansible ring. We prefernot to place these reinforcing rings at the extreme ends of the packer for the reason that if they were there placed the packer might tear away from the rings. We, therefore, place the rings near the ends but securely embedded there- Fig. 2 is a cross-sectional view of the packer,

and

Fig. 3 is a cross-sectional view on the line 3-3 of Fig. 2. s

A head I is secured to a casing 2 by a coupling 3. The head I is provided with a shoulder 4 on which is seated the lower end of a corrugated packer 5. A gland 6 telescopes within the upper end of the head I and the lower end of the gland serves asa means to compress or push downwardly the upper end of the packer. Bolts 1 are secured in wells 8 at the upper end of the head I and nuts 9 may be screwed downwardly to force the gland downwardly to cause the packer to pack oil between the head I through the packer. As fully described in said application 239,458, the packer is sufliciently resilient to permit the passage therethrough of collars and round or square kellys. In other words, it is sufliciently flexible to receive any kind of a kelly or pipe within certain limits.

This packing is frequently subjected to heavy pressures. It is apparent that the lower end of the packer would be subjected to these pressures and there would be a tendency to move the lower end of the packer upwardly so that the greater the pressure encountered, the tighter the packer would engage the head I and the pipe extending through the packer.

downwardly between the lower end of the head and the pipe in case the gland exerted great pressure on the pipe. The function of these rings II is, therefore, to hold the upper and lower ends of the packer against any tendency to flow, that is, the upper and lower ends are reinforced. The

composition of the resilient packer extends through the holes I2- and the packer is bonded to the upper and lower sides and the outer and inner surfaces of the rings as well as to the walls of the holes. The rings are preferably made of metal and the pipe I0 passing I It is to be noted that there would be a tendency for the upper end of the in so that the packer will not tear away from the rings.

We realize that many changes may be made in the specific form of the invention shown by way of illustration herein. We, therefore, desire to claim the same broadly except as we may limit ourselves in the appended claims.

Having now described our invention, we claim:

1. A corrugated packer having outwardly flaring upper and lower ends and rigid reinforcing rings embedded in the-packer in the outwardly flaring upper and lower ends, each of said rings being provided with a plurality of holes through which the packer protrudes.

2. A corrugated packer having outwardly flaring upper and lower ends and rigid reinforcing rings embedded in the packer in the outwardly flaring upper and lower ends, each of said rings being provided with a plurality of holes through which the packer protrudes, the packer being bonded to the sides and edges of the ring and to the side walls of the holes.

3. A'packer having outwardly extending upper and lower ends and having a longitudinally extending bore and rigid reinforcing rings in the said outwardly extending upper and lower ends to prevent the said ends moving radially inwardly.

4. In combination with a hollow head having a seat and a hollow gland having a seat spaced from the seat'of the head and a pipe or kelly passing through said head and gland a packer to pack on the space between said head and pipe or kelly, said packer having outwardly extending upper and lower ends adapted to seat on the seats of said gland and head respectively, and rigid rings embedded in said outwardly extending upper and lower ends to prevent said ends from moving radially inwardly on of said seats.

5. In combination with a hollow head having a seat and a hollow gland having a seat spaced from the seat of the head and a well instrument passing through said head and gland, a corrugated packer to pack oil the space between said head arid well instrument, said packer having out-.
