Abstract
1,037,686. Hydraulic pit props. M. VON LINSINGEN, (trading as BOCHUMER EISENHUTTE HEINTZMANN & CO.) March 13, 1964 [April 1, 1963], No. 10637/64. Addition to 1,010,905. Heading E1E. In an hydraulic pit prop as disclosed in Specification 1,010,905 at least the external prop member for guiding the sealing portion of the prop piston consists of a longitudinally welded tube. In so far as the sealing member 6 is so selected to accommodate misalignment or relative canting of the prop members 1, 2 then the latter may be made from cheap welded tube stock as opposed to being made from accurately worked, seamless drawn or rolled precision tubes as heretofore. The prop is provided with a retraction spring 15 and the seal with a tensioning sleeve 10, see also Fig. 3 (not shown). For details of materials employed and dimensions the Specification should be referred to.
