Abstract

446,310. Portable rock &c. drills. DRINNAN, J., 490, Penistone Road, Sheffield. April 13, 1935, No. 11510. [Class 83 (iii)] A drilling-machine for rock, coal, or other material has a toolholding member c mounted on a hollow spindle b so as to be rotatable therewith and slidable longitudinally with respect thereto, the tool a being retractable within the hollow spindle. The hollow spindle driven through gearing from an electric motor m is carried in a casing s adapted to swivel about the axis of the motor which is at right angles to the spindle axis. Annular slots in the tool-carrying member c are engaged by the slotted walls of the spindle, Fig. 3, to effect a driving connection, the tool being fed axially by hand rotation of a pinion v which is housed in the collar t, Fig. 1, and engages the rack bar q which is fixed to the casing.
