Abstract
Floor-sweeping machine consisting of a housing with a revolving brush mounted rotatably therein and having pinions which are provided at its two ends and which are themselves each connected operatively by engagement to a pair of running drive wheels, the two running drive wheels belonging to a particular pinion being mounted rotatably in a wheel case and the wheel cases being mounted in appropriate housing receptacles so as to be vertically displaceable for adjusting the height of the revolving brush mounted fixedly in the housing, wherein, for a permanent adjustment of the height of the revolving brush without impairing the drive of the revolving brush by the running wheels, each wheel case (26) is retained by means of a wheel-case holder (38) to swing on one leg (44) of a U-shaped adjusting shackle (45), and the U-shaped adjusting shackle (45) is mounted pivotably in appropriate bearings (55) of the housing (11) by means of angled portions (54), shaped on the free ends of the legs (44), and an adjustable wedge face (53) pivoting the U-shaped adjusting shackle (45 ) downwards against the effect of a force accumulator (67) engages on the crown part (51).
