Abstract

518,602. Drilling - machines. HARDYPICK, Ltd., and HURD, F. W. Oct. 18, 1938, No. 30142. [Class 83 (iii)] A pneumatically-operated drilling-machine for rock, coal &c. has handles 5, 6 arranged at the sides of a cylinder 3 containing a rotating vane motor 4, and a tangential socket 7 on the handle 6 which receives a plug 8 attached by flanges and screws 12 and carrying an adapter 9 for a hose connection. A perforated sleeve 14 is mounted between an integral boss 13 and a removable boss 16 in the socket and has an outer covering 19 of absorbent material so that lubricant may be drawn through holes 22 from the annular space 17 around the sleeve by the air passing from the hose to the motor 4. A plug 24 allows the space 17 to be filled with lubricant. The cap 26 which secures the boss 16 in the sleeve carries a throttle valve 29 closed by a spring and opened by a plunger 31 operated by a trigger 32 in the handle 6. A gauge disc 25 is secured between the cap 26 and boss 16 and carries a guide '30 for the valve 29. The adaptor, lubricator and valve may be removed with the plug 8.
