TION 0F WET VIRGINIA.
RKERSBURG, WEST VIRGINIA, A CORPORA- PACKER.
Application filed July 10, 1922. Serial No. 574,063.
To all whom it may concern:
it known that I, JAMES T. CALLANAN,
- the fact that the weight of the tubing, casing or pipe above the packer is not sufficient to cause the rubber as now made to set or expand, and an object of this invention is to provide a packer, the rubber of which may be set or expanded with a minimum weight of tubing, casing or pipe above the same whereby the packer may be effectively utilized in packing shallow wells.
Ex erience has shown that acker rubbers 0 not as a rule expand in t e center. of their length, but have a tendency to roll over on themselves in a number of places throu hout their length and this often makes it di cult to remove them with the tubing or casing,
A further object of this invention is to provide a rubber packer which may be easily removed when desired with the casing, tubin or pipe.
hese, as well as other objects which will readily appear to those skilled in this particular art, I attain b means of the device described in the speci cation and illustrated in the single sheet of drawings accompanyorming part of th1s application.
The single figure of the'drawings repre- 'sents, in longitudinal section, a packer em- 1 its forms, a
bodying this invention.
In carrying out this invention, in one of ength of tubing 1 reduced at its upper end as shown at 2 and having an annular flange 3 at its lower end is carried by a head member 4 which is attached to the lower end of the well casing, tubing or pipe (not shown) by means of threads 5.
Exteriorly, rubber packer 9 is cylindrical, but its inner surface from its upper end 10 to a point 11 is made to conform to and hug the outer surface of tubing 1, the lower end of the rubber packer from point 12 conforms to and hugs the outer surface of tube 1. Between points 11 and 12 the inner surface of the packer rubber is formed with annular depressions 13 and 14 which tend to weaken the packer rubber at these points. A metal anchor ring 15 having its inner diameter less than the outer diameter of the major part of tube 1 is embedded in the rubber packer and anchored to this is a tubular cord fabric reinforcing member .16.
4, a rubber packer 9 is By having a fabric of this character vulcanized in the rubber at or near its center and extending from end to end, the packer at the weakened points is allowed to expand circumferentially to pack, but is prevented from blowing out by gas which passes between the coupling rmg 6 and the outer surface of tubing 1,
The fabric which prevents elongation of the packer rubber facilitates removal of the packer, since the fabric is secured to the anchor ring. With this construction which prevents rolling of the acker. rubber, the rubber will always be lifted from the well by the anchor ring. This method prevents jamming which frequently occurs with packer rubbers of the ordinary type.
Having thus described my invention, what I claim 1s 1. In a well packer, relatively movable members and a sleeve of expansible material confined between said members havin a fabric reinforcement capable of circum erential expansion and but slight elongation.
2. In a well packer and in combination with telescoping members, a rubber sleeve confined between said members having ts inner wall provided with one or more 011- provided with a fabric reinforcement capable of circumferential expansion and but slight elongation.
3. A packer rubber, comprisin a metal ring, a fabric tube depending from said ring and so formed as to be capable of circumferential expansion and but slight elongation, rubber surrounding said ring and said tube and within which said tube and ring are embedded and vulcanized. 4. A packer rubber, comprisin a metal ring,a fabric tube depending rom said ring and so formed as to be capable of circumferential expansion and but slight elongation, rubber surrounding said ring and saidtube and within which said tube and ring are embedded and vulcanized; the inner surface of said sleeve being provided with one or more circumferentially extending depressions of such character and size as to cause said sleeve to expand at said depressions during longitudinal collapsing of the sleeve.
In testimony whereof, subscribed my name this 28th day 1922,
JAMES T. CALLANAN, JR.
