Description

joints to provide for varying lengths of shaft necessary due to their inability to mount the universal joints in the same vertical plane at the center about which the brush was rotated.
The telescoping joint has also been a'source of trouble due to dust and sand enteringand clog-' ging and binding same.
The construction of my sweeper eliminates the telescoping joint, and employs only" one universal joint, by mounting and rotating the brush around a. central column, and supporting said column from the top and sides, sufiicient clearance is provided under the column for positioning the single universal joint so that it is in proper alignment at all times, whether the brush is in right orleft positions, and no sliding or telescoping action is necessary in any part of the shaft. r r
I do not desire to beunderstood as limiting myself to the specific details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made in the construction. l therefore reserve the right to all such variations and modifications as properly fall within the scope of my invention and the terms of the following claims. What I claim as new is: l
1. A road sweeping machine-including a substantially Y-shaped fram having a forward and a pair of rear supporting-wheels, a kingpost supported at the intersection of the members of said frame, a kingpin rotatably mounted in said king post, a cross-beam carried by said kingpin, a rotary brush supported by said cross-beam, a power transmission supported from said frame rearwardly of said brush, means for transmitting tractional power of said rear wheels to drive said transmission and a universal shaft for imparting rotary motion to said brush from said transmission.
2. A road sweeper comprising a frame mountedon wheels, a cross-beam, a kingpost supported by said frame, a rotary brush mounted on a shaft whose ends are supported by said crossbeam, a kingpin rising from said cross-beam at a point midway between its ends and receivable rotatably in said kingpost to oscillatably support said brush, a power transmission, means for driving said transmission from the tractional power 7 of'the'wheels of said frame, a universal joint actuated by said transmission and disposed in vertical alinement with the oscillative axis of said brush, a shaft connected to said universal'j'oint, and means for imparting rotary motion to said brush from said shaft and means jointly carried by said kingpost and pin for holding said brush against oscillation.
3. A'road sweeper comprising a frame supported on wheels, a cross-beam carried by said frame, a'brush mounted on a shaft whose ends are supported by said cross-beam, a kingpin vertically mounted midway between the endsof said cross-beam, a kingpost fixed to said frame and receiving said kingpin, means for holding said kingpin against rotative displacement from selected positions in said kingpost whereby to maintain said brush in fixed angular relation to a road, a power transmission, means for transmitting tractionalpower from the wheels of said frame to said transmission, a universal joint disposed in vertical alinement with said kingpin, a shaft connected to said universal joint and disposed parallel to the axis of said brush, means for rotating said brush from said shaft and mea for raising and lowering said brush;
