Abstract: Apparatus for directing confined sheet-like sprays of water onto the surfaces of rollers in a ground-compacting vehicle.

Abstract: A compactor wheel is rotatably mounted on a vehicle and comprises a plurality of pads disposed on the periphery thereof for compacting purposes. A cleaning bar assembly is mounted on the axle housing of the vehicle and comprises an integral U-shaped frame having a plurality of cleaning bars secured thereon to extend inwardly between the pads of the compactor wheel for removing material therefrom. The bars are secured on a pair of legs of the frame which straddle the compactor wheel in parallel relationship relative to the rotational axis thereof. Each of the legs has an adapter means secured on an outboard end thereof adapted to selectively attach an outboard support bar thereon to form a box-like frame enclosing the compactor wheel.

Abstract: A towed roller for compacting asphalt, earth, etc., including a frame in which a roller drum is journaled, the frame having a forwardly extending drawbar positionable transversely with respect to the frame by hydraulic means to provide an offset in the towed position of the roller, and the frame carrying a transverse shaft which supports at its outer ends rearwardly-extending arms carrying ground-engaging transport wheels, the arms being positionable by hydraulic means to occupy a lowered transport position or to occupy a raised storage position, and drum sprinkler means coupled to be enabled or disabled automatically depending upon the position which the arms carrying the ground engaging wheels presently occupy.
