Abstract

316,334. Wilkinson, H. Nov. 15, 1928. Stopping pipes.-A device for stopping a gas main comprises a barrel A threaded at the basa to screw into the main S and containing a sliding block B carried on rods C which project gas-tight through slots in a cap A<2>. The block carries a frame of laminated springs G between which and a diaphragm D are disposed coil springs E. The zone of the diaphragm in contact with the walls is preferably of leather, and felt pads Q are employed at the points indicated to assist in obtaining a tight fit. A felt washer H is arranged in the barrel to reduce the possibility of an escape of gas. The diaphragm is normally housed in the barrel and is brought into operative position by means of a handle 0.
