Abstract

833,543. Nail extractors. MEVISSEN, H. June 7, 1957 [June 7, 1956 ; Dec. 5, 1956], No. 18236/57. Class 61. [Also in Group XXV] A tool for removing a two-part hollow rail spike 14, 19, Fig. 8, from a hole 12 in a sleeper comprises a rod 28, Fig. 13, carrying members 29 and a rectangular cam 30. The tool is inserted into the spike bore 39 until cam 30 lies between parts 24, 25 and then turned through 90 degrees. The cam separates spike parts 14, 19 and members 29 move beneath webs 27. On withdrawing the tool, e.g. by levering, part 19 is removed. In a modification, the spindle 28, Fig. 16, carries a helix 31 and a core 32 for use with a spike having thread portions in its bore 39.
