Abstract

121,314. Thompson, W. P., (Ingham, T. S., and Pawlick, J. J.). Nov. 29, 1917. Joints with longitudinal pressure and with yielding outer pipe or sleeve compressed.-A hose-pipe joint comprises a union piece formed at one end with a conical nipple A over which is placed a flexible pipe F, and formed at the other end with an external thread G, or an internal thread for screwing on to a metallic supply &c. pipe. The pipe F is gripped in a watertight manner by a somewhat conical end D<1> formed on a screwed sleeve D which engages a threaded surface C formed on the union piece. The sleeve D is formed with a milled exterior, or of square or hexagonal section to receive a spanner for rotating it. In a modification, the nipple A is formed on a portion of the union piece which is of less diameter than that shown, and in this case the pipe F is gripped against the side A<1> of nipple A by a conical surface of reverse slope to that shown in Fig. 1. A flange H may be used to limit the movement of the sleeve D. Reference has been directed by the Comptroller to Specifications 2091/89, 6566/05, and 17362/06.
