Abstract

1330156 Mining dust-suppression means COAL INDUSTRY (PATENTS) Ltd 7 Dec 1971 [22 Dec 1970] 60772/70 Heading E1F Each dust suppression fluid-discharging outlet 4 of a mineral-mining cutter head is provided with a bore 2 that is connected to a threaded nozzle 10 when the nozzle is screwed into a bush 8 inserted into a bore 6 of the outlet 4 to cause the outer diameter of the bush 8 to increase so that the bush becomes jammed in the bore. The bore may be plain or serrated, the serrations being formed by an internal screw thread. Preferably the nozzle 10, bush 8 and outlet 4 have axially aligned through passages. The bush may be of nylon moulding or be the end of a plastics pipe leading into the outlet 4. The nozzle 10 may have a tapered thread for causing expansion of the bush.
