Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
A two part coupling, each part having a plurality of fluid carrying passageways, a plurality of joints each comprising a spigot member and a socket member, the parts being assembled together with each passageway of one part being associated and in alignment with a corresponding passageway of the other part, each passageway in one part carrying a joint member for co-operation with a joint member carried by the corresponding passageway in the other part, hoses secured to one coupling part forming extensions of the fluid carrying passageways therein, said one coupling part comprising a pair of circular flanges secured together in spaced relation and a plurality of recesses formed in each flange, said recesses receiving and retaining the hoses and ferrules attached one to each hose and located between the flanges, said ferrules locating the hoses in a predetermined arrangement about the periphery of said flanges, said joint members of said one part being directly secured to said ferrules so as to be in communication with fluid in said hoses.
