Abstract
425,710. Drilling-machines. WARNE, WRIGHT, & ROWLAND, Ltd., and ROWLAND, J. D., Keeley Street, Birmingham. Nov. 22, 1933, No. 32570. [Class 83 (iii)] A stand for converting a hand and breast drill into a bench drill comprises a base a provided with perforated lugs a<1> for attachment to a bench &c. and a boss a<2> to receive a vertical pillar b. A bracket c is adjustably secured to the pillar by a screw c<2> and has a boss c<3> which slidably receives the shank d of the hand drill. One side of the boss c<3> is open to provide clearance for the driving gear e of the drill and a rectangular projection c<4> on the boss receives the riveted end f<1> of the gear spindle and a screw g which secures the bevel pinion h. A spring k between the boss c<3> and the handle l of the drill normally maintains the drill in the raised position. According to the Provisional Specification, the spring is mounted on a rod slidable through a boss on the bracket and having a fork at the upper end which engages the handle l.
