Abstract

273,170. Burt, L. G. Dec. 13, 1926. Buckets. - A swab for oil wells comprises a tubular member 2 provided with ports 3 for the passage of oil and attached at its lower end to a valve casing 41 carrying a non-return valve 49. Two rubber packers 10, 11 of the shape shown are mounted on the tube 2 between cups 20, 24 and 27, 28 threaded on the tube, and are pressed against the well casing by liquid pressure admitted from the tube through ports 34, 35 to the inner surfaces of the packers. The packers are reinforced with embedded layers of fabric, and may be protected on their inner surfaces by metal sleeves 36, 37. The vaive chamber 44 is tapered to cause the valve to seat centrally. The tube 2 is connected to a tool joint 55 by a ball 56 and split locking sleeve 59.
