Abstract

792,373. Rock-drilling machines. HARDYPICK, Ltd. June 8, 1956 [June 9, 1955], No. 16643/55. Class 83 (3). In a machine for wet-drilling rock, coal, &c. a shaft 11, driven electrically, hydraulically or pneumatically, and which is connected at 33 to the drill-chuck 15, carries a pinion 16 meshing with a gear 18 and forming therewith a pump for supplying flushing-fluid to the drill. Gears 16, 18 rotate in a chamber 17 having inlet and outlet ports 21, the latter communicating with an annular space 25 surrounding the spindle 11 and leading through spindle ports 31, to the interior of the chuck and thence to the hollow drill. Packing is provided at 30, 27 and 39 to prevent escape of fluid. A cover 35, with inturned flange 37, protects the thrust-bearing 32 from dust &c.
