A NOVEL PIPE COUPLING

Who has not suffered (asks "Chambers' Journal") at one time or another from the inconvenience arising from the bursting of a load water-pipe or from a broken ga<s-pipe'.' A trained workman has been essential to I'epuir the .joint effectively b.y wiping, but often the mishap tKX-iWs when such assistance is not readily available. An ingenious inventor has devised a novel coupling for such contingencies, which can be used by an intelligent person without any special training, and which requires no brazing, soldering, or any other similar operalion. What is more, as exacting tests have proved <onclu.siveiy, the joint be comes the strongest part. Seeing that there is no messinof* in performing tile operation, and that the repair orth generally be effected withltt two o.i- three ihinutes. the coupling very fully meets all requirements. The coupling is rilade up of an imier tubular ring-piece, tapered longitudinally on its outer surface and towards each end from the centre, which fits into a cap formed by one half ■screwinrr over the other. Tn order to complete the joint, all that that is necessary is to sever the pipe at the point where it has burst, and to slio one part of the dap over each -zv.d. The end of the pipe is then "belled" cut slightly so as to allow the double tapered tubular ringpiece to be introduced. The two parts of the cap are then drawn together over the tubular ring-piece and screwed up, the cap Oomprisintr a male and female piece. As the cap~i.t .•■erewed up tightly the tapers of the tubular lining are driven farther ftid farther and lllore tightly into theends uf the pipe. When finished the joint is as sound and as tight as it can be made by wiping. At present the coupling is made in six *izes from a- quartet' to threcquartcrs of an inch; and its uss is sanctioned extensively by the authorities concerned, as it is found that the joint completely prevents both gas an water leakage. For connecting pipes to gas cookers and stoves it is ideal. It is also a useful adjunct to a farm and an estate, where during a severe winter a burst pipe i'S by no means unusual, as the. defect can • be- effectively remedied by ihis ingenious invention without delay, skill, or tools.
