Abstract

403,996. Portable drilling - machines. HARDYPICK, Ltd., Heeley, Sheffield, and HURD, F. W., 70, Cunningham Park, Harrow, Middlesex. June 7, 1932, No. 16082. [Class 83 (iii).] A portable drilling-machine with self-contained electric motor has a hollow tool spindle passing axially through the motor adapted to drive a drill at either end and a casing for receiving a cable and switch arranged tangentially with respect to the motor. The hollow spindle e, having a central driving member p, is mounted by means of ball bearings in the cylindrical casing a; hollow handles k, m are provided integral with the periphery of the casing enabling the machine to be turned over and the opposite end of the spindle used when a reverse drive is required, the handle k is extended tangentially of the motor to form a casing for the cable to the motor and the switch.
