Abstract
1441309 Mineral mining picks CINCINNATI MINE MACHINERY CO 2 Aug 1973 [11 Aug 1972] 36754/73 Heading E1F Apparatus for use in a mining machine comprises mounting means 16 having a perforation 23 for receiving a shank 28 of a cutter bit 26 and having mounted thereon means 41 comprising a body 42 having at least one tip 49, located to at least one side of the cutter bit when mounted, for breaking cores of material left between the paths of travel of adjacent bits. The core-breaking means 41 is received in a complementary recess 38, Fig. 7, or (67), (82), Figs. 17, 18 (not shown) in the mounting means and retained in place by abutting shoulders on he cutter bit 26, which is itself retained by a rod 35 encased in a body 36 of resilient material, or of split rings (135), (136). Alternatively the core-breaking means may not abut the cutter bit, being retained in a complementary recess in the mounting means by for example a resilient rod (63), Figs. 9, 10, 28 (not shown) compressed in a transverse bore in the corebreaking means and frictionally engaging the walls of the recess, by a pin (149), Fig. 30 (not shown) engaging in bores in the mounting and the core-breaking means, or by a resilient retainer (194), Fig. 36 (not shown) similar to the retainer 36. Or the core-breaking means and the cutter bit may be formed as an integral unit, Figs. 26, 27 (not shown). Or the core-breaking means may be separate elements 96, Fig. 22 with conical cutting heads, and shanks which are received in perforations 93, 94 in mounting means 90, located to either side of the perforations 23 for the cutter bit, and retained either by friction or by a pin (110), Fig. 24 (not shown).
