Abstract
728,225. Pipe joints. SMITH & CLARKE, Ltd., T., and SALTER, T. T. March 25, 1953 [April 1, 1952], No. 8217/52. Class 99 (1). [Also in Group XXI] In a plug unit, for introducing water under pressure into bore holes, resilient rings 6 expand radially to engage the sides of a borehole when compressed axially between the end surfaces 2 and 5 of concentric tubes 1 and 4. Relative axial movement between the tubes is caused by the operation of a toggle mechanism 12, 13 positioned between a housing 3, rigidly connected to the tube 1, and a collar on the tube 4. The collar abuts against a stop 8 which can be moved to different positions along the threaded portion of the tube 4 so that the rings 6 can be compressed axially and thus expanded radially to varying amounts. Water is passed into the borehole through the tube 4. Specification 639,074 is referred to.
