Abstract

663,646. Pipe couplings. BRITISH TANKER CO., Ltd., HUTCHISON, W. M., and HOPKINS, K. W. Nov. 25, 1949 [Oct. 26, 1948 ; Nov. 18, 1949], Nos. 27848/48 and 29561/49. Class 99 (i) [Also in Group XXV] Two or more arcuate channel-section members 10, 11 having inclined inner walls are pivotally connected together and embrace the flanges of pipes to be coupled, and quick-release means connect and draw together the free ends of the couplings so that clamping pressure is exerted to press the flanges together. The means may comprise a roller 18 eccentrically pivoted on a pair of links 20 connected to one free end of the coupling and a handle 24 to rotate the roller when engaged on a seating 22 of the other free end of the coupling. In a modification, the members are connected by pairs of links to form a flexible chain and the means comprise a bolt pivoted to one free end of the coupling and a lever having rounded forked ends that embrace a nut engageable with the bolt and co-operate with a seating on the other free end of the coupling so that a fine adjustment of the clamping pressure is obtained. Specifications 402,490 and 412,186 are referred to.
