Abstract
A tooth holder for a cutter of a mining machine has a holder body fixed to the cutter and normally displaced thereby in a predetermined longitudinal direction. This body is formed with a longitudinally generally forwardly open bore, an outer transversely directed seat face adjacent the bore, and a feed passage opening at the outer seat. A sleeve is received in the bore and a cutter tooth is received in the sleeve. A separate nozzle body is formed with a nozzle passage having one end communicating with the feed passage at the seat and an opposite end forming a longitudinally generally forwardly open spray mouth, and a face complementary fitted to the outer seat face. A fluid is supplied under pressure to the feed passage so that the fluid exits the spray mouth. The nozzle body is releasably secured by screws or the like to the holder body with the faces engaged tightly together.
