Abstract:
1. A towable lawn sweeper, comprising: a housing; a hitch assembly rigidly coupled to the housing; a sweeper assembly rotatably coupled to the housing, the sweeper assembly comprising: an elongate axle; a pair of brushes, each brush being coupled to a planar, elongate attachment bracket extending the length of the brush, each attachment bracket having a plurality of apertures therethrough; a plurality of clamps, each clamp having an arcuate portion and a pair of planar portions opposingly extending from the arcuate portion, the planar portions each having an aperture therethrough; and a set of fasteners, a first brush being oriented such that its bristles extend away from the axle at a predetermined circumferential position at the first end of the axle, and such that its bristles extend from an opposing circumferential position at the second end of the axle, and a second brush being oriented such that its bristles extend away from the first end of the axle at a circumferential position generally opposite those of the first brush at the first end of the axle, and such that its bristles extend from an opposing circumferential position at the second end of the axle, the opposing circumferential position being generally opposite that of the first brush, wherein the pair of brushes are secured to the axle with the clamps, the clamps being arranged in pairs and facially adjacent to each other such that the arcuate portion of each clamp conforms to the axle and the planar portions of each clamp are proximate the attachment brackets, apertures of the facially adjacent clamps and the apertures of the attachment brackets are in alignment with each other, a fastener extending through the aligned apertures to secure together the clamps, brushes and axle, thereby maintaining the orientation of the brushes.
