Floor sweeper with split brush assembly
First Claim
1. A floor sweeper for recovering material from a surface to be cleaned comprises:
- a foot assembly adapted to move forward and backward across a surface to be cleaned and including a housing forming a brush chamber having a bottom opening;
a pair of driving wheels mounted to the housing for supporting the housing above the surface to be cleaned, each driving wheel including a driving gear;
a split brush assembly rotatably mounted within the brush chamber and adapted to contact the surface through the bottom opening, the split brush assembly including two independently mounted brushes mounted to the brush chamber mounted for rotation within the brush chamber independent of each other, each of the brushes having a brush gear that is in registry with one of the driving gears;
a single dirt receptacle mounted to the housing laterally to the brush chamber and in registry with the split brush assembly to receive dirt and debris from the brushes as the foot assembly moves forward or backward across the surface to be cleaned;
an upper dirt passage between the brushes and the dirt receptacle; and
a lower dirt passage between the brushes and the dirt receptacle, wherein the lower dirt passage is positioned below the upper dirt passage and separated from the upper dirt passage by a first guide that is out of contact with the split brush assembly;
whereby each driving wheel drives one of the two brushes independently of the other brush so that the brushes can be rotated at different speeds as the foot assembly moves along the surface to be cleaned.

Abstract
A floor sweeper for recovering material from a surface to be cleaned comprises a handle assembly pivotably attached to a foot assembly. The foot assembly comprises a housing forming a brush chamber having a bottom opening. The foot assembly comprises a pair of driving gears and a split brush assembly rotatably mounted within the brush chamber and adapted to contact the surface through the opening. The brush assembly comprises two separately-rotatable halves each corresponding to one of the driving gears, with each half comprising a brush core, brush paddles or bristles affixed to an exterior of the brush core, and a brush gear adapted for rotation with the brush core. Each brush gear is driven by a corresponding driving gear to the corresponding brush core as the floor assembly is moved across the surface in order to drive the brushes to cleaning of the surface.
