Abstract: THE HOUSING OF A CARPET SWEEPER OR THE LIKE HAS A RECESS IN ITS TOP WITH A FLOOR WHICH IS FORMED TO ACT AS A SPRING. THE LOWER END PORTION OF THE SWEEPER HANDLE IS MOUNTED IN BEARINGS AND IS PIVOTABLE FROM AN UPRIGHT POSITION TO AT LEAST ONE HORIZONTAL POSITION. THE HANDLE END ENGAGES THE RECESS FLOOR DURING PIVOTING, AND THE INCREASED FRICTION HOLDS THE HANDLE AND HOUSING AT A SUITABLE ANGLE.

Abstract: One or more auxiliary brushes are floatingly mounted for sweeping litter from either a carpeted or smooth floor into the path of the main transverse sweeper brush means. The drive for the auxiliary brushes is internal and does not depend upon rotation of the sweeper''s main drive mechanism. A caster device drives the auxiliary brushes through a non-circular connection having substantial play therein so that the brushes will readily position themselves to conform to the contour of the surface being swept. Means are provided to limit deformation of the brush bristles against the floor.
