HENRY KEWLEY, OF MADISON, OHIO.
IMPROVEMENT lN STOP-WATERS FOR OIL-WELL TUBING.
Specification forming part oi'Lctters Patent No. 58,837, dated October 16, 1866.
To all whom it may concern:
Be it known that I, H. KEWLEY, ot' Madison, in the county of Lake and State of Ohio, have invented certain ne'w and uset'ul Iniprovemeuts in Stop-laters for OillVell Tubing; and I do hereby declare that the following is a full and complete description ot' the construction and operation of the same, retcrence being had to the accompanying drawings, making a part of this specilication, in which- Figure l is a side view ot' the stop-water. Fig. 2 shows the relation of theseveral parts to each other; Fig. 3, detached transverse section; Fig. 4, a frictionroller washer; Fig. 5, a plain dat washer.
Like letters refer to like parts in the several views presented.
A, Fig. 2, is a brass tube, to which the collar B and the ilange G are attached. On the upper and lower end of the tube is cut the thread D D. It will be remarked that the two extreme ends ot' the tube are of the saine size, but that an inch or so from the lower ends the thread is enlarged in its diameter. The purpose of these screws will hereinafter be described.
E, Figs. 1 and 2, is a strong leather sack or bag, and is tted to the outside of the sleeve F, Figs. 2 and 3, th'e lower end resting upon the iange Gr, which is a little less in diameter than the sack. Tithin this sack, and ceiling around the sleeve F, is the spring H. This spring plays loosely in the sack and around the sleeve.
When the spring is placed in its proper position in the sack, the sack is then tilled with sand, thc spring being surrounded and buried in it. The plain washer I, Fig. 5, is 'then slipped on over the end of the sleeve, and lies upon the upper end ot' the sack. rlhis washer, corresponding relatively to the washer G at the lower end, thereby places the sack between two washers. Immediately upon the plain washer is placed the frictionroller washer J, Fig. 4t.
The sack and washers, on being properly arranged, thetube A is then passed into the sleeve, the lower end of the sleeve being provided with a female screw, and the end of the tube, as above described, having two threads cut upon it, one of larger diameter than the other, the largest thread is screwed into the sleeve until the ilange C comes down upon the friction-washer J. On screwing the tube into the sleeve by means ot1 the tube-tongs, the sack is compressed so as to cause it to expand outward, the degree of expansion being as the force applied. The friction-washer being placed between the plain washer and the collar O prevents any great degree ot friction resulting from the screwing ot' the two parts together.
A section of well-tubing, on being screwed to the lower end of the tube, which, as above described, is smaller than that screwed into the sleeve, also sections ot well-tubing, 011 being screwed to the upper end ot' the tube, the water-stop is then lowered into the well, and when at the desired depth the tube is screwed into the sleeve, causing, as above stated, an outward expansion of the sack until it presses against the sides of the well, making thereby a wa-ter and gar tight joint, the oil passing up through the lower section of tubing', also through the sleeve to the tubing above, where it is free from water and to be discharged in the ordinary way.
In order to withdraw the stop-water from the well, the tube is unscrewed, -releasing thereby the pressure from the ends ot the sack. By the force ot' the spring H, above described, the sack is elongated, which releases its outward pressure against the sides of the well. It then can be lifted out in the ordinary way.
To prevent the stop-water from turning in the well while screwing the tube A into thc sleeve, the lower end ot' the sleeve is provided with a pair of dogs, K K. These dogs are pointed with steel, and are connected tothe sleeve by the pins E E, forming a joint. It will be remarked that the points of the dogs project out a little beyond the side of the collar G and the sack, and are retained in this position by the springs M M.
On screwing the tube down into the sleeve, should the sleeve turn, the dog K catches into the wall of the. well, and thereby prevents the stop-water from turning in that direction, and so, on reversing the movement of the screw, the dog K catches into the wall and prevents it from turning in the other direction. The peculiar rounded forni given to the outer side of the dogs prevents thorn from catching,r in
`the wall on withdrawing,v the stopwater from the Well.
What I claim as my invention, and wish to secure by Letters Patent, is-
1. The spring II, the sack E, and. the tube F and the flange G, in combination with the Washers I and J, in the manner and for the purpose set forth.
