Abstract
618,817. Boring and drilling. HARDYPICK, Ltd., and HURD, E. W. Nov. 11, 1946, No. 33449. [Class 83 (iii)] A machine for drilling and boring rock &c., in which water is supplied to a hollow tool, comprises a chuck 13 rotatably housed in a water-box 27 and carrying the axially slidable tool 15, and a water-feed chamber 16 with an inlet 33 and outlet 24 controlled by a spring- pressed valve 19, the outlet containing a hollow plunger 21 which abuts the tool and opens the valve under the pressure of the machine upon the tool during drilling. An oil reservoir 40 is provided for lubricating rings 38, surrounding water seals 37, via ports 42.
