First Claim
1. A carpet or floor sweeper comprising:
- a housing displaceable forwardly and oppositely backwardly in a normal direction of travel and having an open bottom;
a plurality of floor-engaging wheels rotatable on said housing;
a cover plate closing said bottom of said housing and formed with a central hole and forming to at least one side of said hole a dust-catching receptacle;
means pivoting said plate on said housing about an axis extending transverse to said direction;
a rotatable brush elongated transverse to said direction extending through said hole;
means mounting the elongated brush on said cover plate for rotation of said elongated brush about its longitudinal axis; and

Abstract
A floor or carpet sweeper has a hollow housing provided on its lower side with a plurality of floor-engaging wheels. The bottom of the housing is closed by means of a cover plate which is pivoted on the housing about an axis perpendicular to the forward and backward direction of travel of the housing during sweeping. This cover plate is formed with a throughgoing hole and is provided with upwardly bent tabs on which a cylindrical brush is rotatably mounted, this brush extending through the hole in the plate. In addition the ends of the brush are engageable with the wheels when the cover plate is closed on the housing so that the brush is rotatably driven by these wheels. A magnet holds the cover plate in place on the bottom of the housing and engages against an inclined surface on this cover plate. This magnet can be moved along the inclined surfaces so as to vary the height setting of the brush.
