Abstract: The present invention provides an adjustment mechanism and methods for adjusting the alignment of a powered cylindrical brush mounted to a surface maintenance vehicle relative to a surface to be maintained or cleaned by the vehicle. The device is preferably disposed upon the idler-side of a powered rotating cylindrical brush assembly and the adjustment preferably occurs via use of an eccentric cam member providing a range or motion, or pivot location, through or about which the idler-side mounting location of the cylindrical brush may be adjusted to improve contact with the surface. The present invention enables such adjustment without decoupling the rotating brush from its couplings (both supportive and rotational coupling), and any coupling to a drive mechanism for driving the rotating brush into rotation. The rotating brush so adjusted will benefit from improved mechanical cooperation between the bristles of the brush and the surface to be cleaned.

Abstract: In a floor scrubbing machine, side squeegees for control of water on the floor are mounted with linkages that include vertical pivots so the squeegees can swing from side to side. They are interconnected with a tie rod so they swing in unison. A rear squeegee swings to one side or the other when the machine turns due to friction with the floor. A push-pull cable is connected between the rear squeegee mounting linkage and the linkage of a side squeegee to cause the side squeegees to swing or steer during turns. This positions them to effectively control water on the floor during a turn, and reduces squeegee wear. An alternative to steering them with the rear squeegee is to steer them with a hydraulic cylinder plumbed into the machine's power steering system.
