Abstract

14,809. B÷nten, F., [Manegold, (Nachfolger), J.]. June 24. Hand and breast drills of the type operated by cranks and bevel-wheels have means whereby the drills may be driven at more speeds than one. This is effected by means of a pinion e fixed to the spindle c', which also carries the bevel-wheel c, and another pinion f gearing with the pinion e, the wheels c, f each having an undercut groove f<1> so that a crank handle may be attached to either. An additional wheel and pinion may be fitted to give a greater speed, the last wheel of the train having means for attaching the handle.
