Abstract

The pavement cleaner of the present invention comprises a housing, a brush assembly, and a snow thrower. The housing includes a pair of sidewalls, an endwall, and a topwall, which are operable to form substantially a rectangular box. The housing includes a pair of wheels, each disposed on suitable journaled axle means distally from the terminal end opposite the endwall at the lower terminal edge of each of the respective sidewalls. The housing is provided with a trailing wheel disposed centrally from the endwall on a suitable bracket, the wheel being journaled for rotation and operable to provide dirigible means for the pavement cleaner. A handle, having a pair of bracing bars, is fastened on the sidewalls distally from the endwall. The brush assembly includes a multiplicity of outwardly projecting bristles fastened on a suitable axle. The axle is carried in bearings mounted in vertically disposed slots in each of the sidewalls. The axle is set in rotating motion by means of a suitable drive train. The brush assembly includes a pan having a substantially rectangular bottom wall, a pair of sidewalls fastened upstandingly to the terminal side of the bottom wall, and an endwall fastened upstandingly to the bottom wall and the sidewalls. The pan is operable to be detachably fastened within the housing at its end opposite the endwall. The brush assembly includes a deflector operable to guide material from the bristles into the pan. The pavement cleaner may include a snow thrower including a pan. The pan is provided with a portion convexly curved with respect to the housing and a pair of side deflector walls fastened at each end of the curved portion. The pan is operable to closely conform to the transverse configuration of the end opposite the housing endwall. The snow thrower includes a blade fastened on a suitable axle. The axle is carried on journal bearings which are fastened to the deflector walls. The blade and axle are set in rotating motion by means of a suitable drive train.

Claims

1. A pavement cleaner, comprising a housing including a pair of sidewalls, an endwall, and a topwall forming a substantially rectangular box having an opening at the end opposite said endwall;

a pair of wheels journaled for rotation on axle means distally disposed from the end opposite said endwall at the lowermost terminal edge of each of the respective sidewalls of said housing;

a dirigible trailing wheel pivotally mounted and journaled for rotation on a bracket centrally disposed on said endwall of said housing between said sidewalls; and

a handle having a pair of rearwardly disposed handle bracing bars fastened on said sidewalls distally from said endwall, said handle having a barlike handle fastened to said bracing bars at their respective ends opposite said sidewall connection;

a brush assembly including a multiplicity of outwardly projecting bristles fastened on a shaft, said shaft being carried in suitable journal bearings slidably mounted in vertically disposed slots in said sidewalls of said housing, said shaft being rotatably moved in response to movement of said wheels in communication with a drive train interconnected with said shaft;

a pan having a substantially rectangular bottom wall, a pair of upstanding pan sidewalls fastened to the terminal sides of said bottom wall, and an upstanding pan endwall fastened to said bottom wall and to said pan sidewalls, said pan being operable to slidably engage opening in said housing at its end opposite said housing endwall to close said housing, and being operable to be detachably fastened to said housing; and

a deflector operable to guide material from said bristles into said pan; and

a snow thrower means including a thrower pan, said thrower pan having an end portion being convex with respect to said housing and a pair of side deflector walls fastened at opposite sides to each end of said portion, said thrower pan being the transverse configuration of the end opposite said endwall in said housing, said thrower pan having means operable to detachably fasten said snow thrower means to said housing; and

a blade disposed within said thrower pan, said blade having a diameter distally smaller than said thrower pan, said blade being fastened to a axle means, said axle means being carried on suitable journal bearings fastened to said deflector plates, said blade and said axle means being being rotatably moved in response to movement of said wheels in communication with a suitable drive train interconnected with said axle means.

2. The apparatus of claim 1, wherein said trailing wheel includes a crank actuated adjusting means operable to raise and to lower the rearward terminal end of said housing in response to rotation of said crank adjusting means.
