Abstract
229,991. Ross, D., Weiser, R. F., and British Mannesmann Tube Co., Ltd. Dec. 21, 1923. Indicating leaks.-In apparatus for testing joints 1 in a pipe line 2, 3, of the type which comprises an expansible casing, carrying an indiarubber band 6<1> having lateral projections 6, which forms in conjunction with the inner face of the piping a closed annular chamber 7 into which fluid under pressure is forced, the expansible casing consists of a split segmental ring 4 and a segmental closing member 5, disposed in a gap 9 arranged between the ends of the ring, and the means for expanding the casing consists of a bolt 10, connecting a lug 13 on the ring 4 with a lug 11 on the member 5, and toggle mechanism 16, carried by a collar 17 slidably mounted on said bolt, which co-operates with projections 18 on the ends of the ring 4. The ring is provided with an attachment 8, which is put into communication with a source of fluid under pressure and a pressure gauge, any escape of fluid through the joint causing a reduction in the pressure which will be indicated on the gauge.
