Abstract

462,787. Pipe couplings. BRAND, J. April 2, 1936, No. 9767. [Class 99 (i)] Drain &c. pipes a, b are coupled by a rubber sleeve d which is stretched over flanges c on the ends of the pipes and is provided with end beads e which bear resiliently on the pipes adjacent said flanges. A split ring g, which is tapered at its ends and has an annular outwardly-projecting bead h at the middle, may be interposed between the pipe ends. Reference has been directed by the Comptroller to Specifications 6273 /02 and 21629 /07, [both in Class 99].
