Abstract

554,002. Pipe joints ; electric couplings. MELSOM, W. A., and BOWDEN (ENGINEERS), Ltd. Feb. 4, 1942, No. 1486. [Class 99 (i)] [Also in Group XXXVI] In a coupling for pressure hose having two or more layers 1, 2 of resilient material such as rubber and one or more layers 3 of flexible reinforcing material such as canvas or metal braiding, the coupling comprises a sleeve 5 and an insert 6 and an annular portion of the layer 2 is removed and replaced by a separate ring 9 ; the sleeve 5 is then radially contracted at 8 around the ring 9, so that the part of the layer 2 trapped between the ring 9 and the closed end 7 of the coupling is under considerable pressure. The sleeve 5 may be of brass, aluminium alloy, low-carbon steel or phosphor bronze and may be contracted by radially moving dies or by an extrusion die or a rotary swaging machine. The ring 9 may be of softer metal than the sleeve, for example aluminium, annealed brass, copper or lead, or of compressed fibre, canvas embedded in rubber, or rubber having a greater resistance to flow than the hose material. The ring 9, when metallic, may be in electrical contact with a layer 3 of metal braiding. The sleeve 5 may also be compressed at the zone 11, the zones 8, 11 preferably being in thickened parts of the sleeve. In modifications, (a) the sleeve 5 has an inner annular groove surrounding the ring 9, which is thicker than the layer 2 of the hose ; (b) the insert 6 is integral with the sleeve 5, and the shouldereddown end of the sleeve and insert is adapted to receive a nut coupling as described in Specifications 540,489 and 540,490. In forms having a separate sleeve and insert, either the sleeve or the insert may engage the complementary component of the coupling.
