Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
223 words
A pipe Connection for connecting two pipe ends, collars fixed at each pipe end, a plug part joined to one end of one of the collars, a socket part surrounding the collar and the plug part, ring gaskets between and sealingly engaging the socket part and one collar and the socket part and the plug part, an inwardly directed shoulder at one end of the socket part and on outwardly directed shoulder at the other end of the socket part, a pair of pivotally connected shell sections which when closed engage at one end said collar at one pipe end and the outwardly directed shoulder on the socket part at the other end thereby functioning to keep the pipe connection together, a pipe piece having attached at one end a ring part, said ring part having a wedge-shaped tapered face, a complementary wedge-shaped taper on the face of the inwardly directed shoulder of the socket part, said pipe piece and ring part fitted under the socket part axial outwardly of the pipe collar at that end of the pipe, handles provided on the pipe piece at the opposite end from the ring part, whereby upon turning the pipe piece on the pipe the cooperating wedge-shaped tapers on the ring part and the inwardly directed shoulder permit off angle connection of the pipe ends.
