Abstract

A dual deflector element is disposed centrally of the lower unit of a floor sweeper and is adapted to serve two uni-directional brush rollers, disposed between the deflector and respective front and rear dust pans. The front brush roller tends to be more efficient in picking up large debris than the rear brush roller. A single center-mounted drive means is provided which serves both brush rollers. The lower unit frame or housing includes end walls and a central tansverse top portion extending therebetween, and a pair of upwardly removable dust pans are adapted for insertion between the end walls adjacent the forward and trailing edges of the top portion. Latch devices asociated with the end walls cooperate with the dust pans ends to hold the pans in position. The housing top portion includes downward extending end flanges which are riveted to the housing end walls, with the rivet heads forming the bail detents. End caps are mounted over the housing end walls and cooperate therewith in mounting springs, the ends of which form stub axles for four sweeper support wheels. The four support wheels float generally vertically on their springs, with upper stops for the springs serving also as lower seats for the flanges of the housing top portion. The upper stops permit the four support wheels to floatingly rise further than the drive wheels.
