Abstract
586,228. Repairing water pipes; branch connections. YOUNG, T. N., and GLEDHILL, E. G. B. Dec. 18, 1944, Nos. 31366/45 (divided out of 586,226) and 3457/45. [Classes 99 (i) and 99 (ii)] [Also in Group XXII] In a method of repairing a damaged water pipe the flow of water at the leak or breakage is stopped with the exception of a trickle or drip and a short length of the pipe up-stream of the leak is frozen, the damaged part is cut out and replaced by a sound part and the frozen length is thawed. Freezing may be effected by apparatus such as described in Specifications 586,225 and 586,226. A sealing clamp adapted to be applied to the broken part 4 of the pipe comprises two semi-cylindrical hinged parts 7, 9 secured together by bolts 13, and a split resilient sealing sleeve 14. The sleeve has an inner helical groove 18, a longitudinal groove 19 and a radial passage 20 through which water flows to the dripcock 21. In repairing a lead pipe flow may be stopped by deforming the pipe up-stream of the leak and a controlled trickle is effected by piercing the pipe up-stream of this point and controlling the flow by a drip cock. The tapping device comprises a frame 34, Fig. 9, having a hook portion 30 in which the pipe rests, and an arm 35 adapted to receive a threaded spindle 36 which carries a cross member 40 slidable on the frame and provided with a piercing tool 41. Water flows through passages 43, 45 in the tool 41 and member 40 to a drip cock 46. The part of the pipe to which the evaporating chamber of the refrigerating device is applied may be straightened by the application of a two-part clamp.
