Abstract

974,536. Wells &c. FMC CORPORATION. Oct. 3, 1962 [Oct. 5, 1961], No. 37448/62. Heading E1F. A bushing 10 for mounting in a well-head structure has a bore 20 to receive a tubing hanger 86, the bore communicating with a slot 24 formed transversely through the bushing, and a support lug 52 in the slot being movable into the bore to engage and lock the hanger therein. The slot also houses a lug 50 for engaging a hanger in a bore 22, both lugs being pivoted about a pin 54 and being urged by springs 66, 60 away from the bores. Lugs 32, 34 are similarly mounted in a slot 26. Screws 81, ... 84 are screwed inwardly to move the edges 70, 72, 74, 76 of the lugs into the bores to support the hangers. Supporting surfaces 88 on the hangers are inclined and interlock with complementary surfaces at the edges of the lugs to prevent the lugs from swinging outwards should a screw be retracted.
