Abstract
276,265. Bender, W. March 28, 1927. Drilling-machines. - A portable electricallydriven drilling machine, which may be used for grinding and polishing, is provided with two spindles perpendicular to each other, and operatively connected by bevel gears, either spindle being adapted to receive a tool or a hand-driving crank. The machine comprises a casing 10, with a cover 11, and a built-in electric motor 12 whose shaft 13 carries a pinion 15 engaging a gear 16 secured to the boss 20 of a bevel pinion 19 gearing with a bevel wheel 21. The wheels 16, 21 are secured to spindles 17, 22 respectively, each spindle having a tapered socket for receiving a tool 23 or a hand crank 25 alternatively. The motor shaft is extended through the cover at 14 to receive a flexible-shaft for driving a grinding, polishing, or like tool. Sockets are provided on the casing and cover to receive handles 28, 31 respectively, which may serve as a means of support on a drill-stand, the handle 31 being hollow to allow a fan 35 to draw air into the casing for cooling the motor. A motor switch 37 is placed where it can be operated by the hand which grasps the handle 28.
