Abstract

408,524. Portable electric drilling &c. machines. DUSS & BENDER SPEZIALFABRIK FUR ELEKTROWERKZEUGE GES., Neubulach, Wurtemberg, Germany. Sept. 28, 1933, No. 26758. Convention date, April 26. [Class 83 (iii).] In an electrically driven portable hand drill or like machine, a tool or holder therefor is adapted to be coupled selectively to one of a number of drive shafts (two in the embodiment described) 8, 9 connected by gear trains to the motor shaft 4, the drive shafts being arranged concentrically to the axis of the motor in a cage 7 rotatable about the said axis, the machine having a fixed opening 12 for the tool or holder, positioned so that on rotation of the cage any selected drive shaft can be moved into alignment with the opening so as to be coupled to the tool or holder (not shown). A gap 14 in the casing exposes the lower part of the rotatable cage enabling it to be manipulated by hand.
