First Claim
Patent Images
1. A brush for a sweeping machine adapted to remove mixed aspect ratio debris from a surface, said brush comprising:
- a core, said core having a core surface;
sweeping material attached to said core and extending radially outward from the core surface, said sweeping material forming a plurality of first regions of sweeping material and a plurality of second regions devoid of sweeping material, said first regions bounding said second regions of the core, said second regions devoid of sweeping material forming pockets for entrapping debris;
a plurality of third regions of sweeping material; and
a plurality of fourth regions devoid of sweeping material, said first and third regions of sweeping material bounding said second and fourth regions devoid of sweeping material, said first and third regions of sweeping material having different geometric shapes.

Abstract
A sweeping machine for picking up debris from a surface includes a frame and wheels attached to said frame to support the frame of the sweeping machine over the surface being swept. A cylindrical brush is rotatably attached to said frame. The cylindrical brush includes a tubular main body and tufts attached to said tube such that the tufts extend radially outward from said tube. The tube has regions devoid of tufts bounded by regions having tufts. The sweeping machine also includes a mechanism for rotating said cylindrical brush.
