Abstract

142,419. Bostel, F. J. Dec. 24, 1919. Indicating, locating, and repairing leaks.-A device for testing and repairing drains &c. consists of a collapsible rubber air container 4 closed at each end by heads 5 and bolted to two stout rubber disks 3. The bolts 6 are provided with eyes 9 and a chain or rod is attached at each end to one of the eyes in order to take the longitudinal stress. In one of the bolts 6 is drilled a duct 11 through which air is pumped into the container. A wire coil 14 surrounds the tube 4 and serves to protect it from damage or to prevent undue expansion. In operation, the space surrounding the container is filled with liquid cement and the device is inserted in the drain. On pumping air into the container, pressure is exerted on the cement, tending to force it into the leaks or faults in the drain. The device is then gradually drawn or pushed through the drain. The apparatus may be used for testing purposes by connecting a pressure gauge to shew the pressure within the container. The presence of a leak is indicated by a drop in pressure due to expansion of the container.
