A sweeping machine includes a chassis with wheels supporting the chassis on a surface to be swept. There is a brush mounted on the chassis for rotation in a direction to throw debris over the brush and into a debris hopper mounted on the chassis behind the brush. A flap assembly is positioned in front of the brush and closely adjacent thereto. The flap assembly has a flexible lip which is in contact with a surface being swept during its normal position. There is an operator control and a connection between the operator control and the flap assembly for raising and lowering the flap assembly between the normal position in which the flexible lip is in contact with a surface being swept, a first raised position in which the flexible lip has been raised substantially vertically a small distance above the surface being swept, and a second raised position in which the flap assembly has been raised and pivoted in a forward direction relative to the first position to permit debris to pass under the flap assembly to an area about the rotatable brush.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] A sweeping machine including a chassis, wheels for supporting the chassis, a brush mounted on the chassis for rotation in a direction to throw debris over the brush and into a debris hopper mounted on the chassis behind the brush,a flap assembly positioned in front of the brush and closely adjacent thereto, said flap assembly having a flexible lip which is in contact with a surface being swept, an operator control and a connection between said operator control and said flap assembly for raising and lowering said flap assembly between a normal position in which said flexible lip is in contact with the surface being swept, a first raised position in which the flexible lip has been raised substantially vertically a small distance above the surface being swept, and a second raised position in which said flap assembly has been both raised and pivoted in a forward direction relative to said first raised position to permit debris to pass under said flap assembly to an area about said rotatable brush.
