Abstract
1,178,845. Spanners. L. JOHNSON, and K. ROBOTHAM. 2 Aug., 1967 [18 Aug., 1966], No. 36965/66. Heading B3N. A spanner for screwing up a pipe coupling 10, comprises ends 28, 32 forming different diameter apertures 34, 36, and equally spaced recesses 38, 40 for engagement with projections 12 on the coupling.
