ABSTRACT:
In general, apparatuses or machines for compacting the shoulders of roads include a plurality of wheels in side by side relationship, which are merely rolled over the gravel shoulder of a road. Such machines rely on the weight of the wheels to effect compacting. An apparatus for effecting more efficient compacting includes a frame for connection to a towing vehicle, a fixed arm extending rearwardly from the frame, a pivot arm pivotally connected to the fixed arm for limited rotation around an axis perpendicular to the direction of travel of the apparatus, crossbars pivotally connected to the pivot arm for limited rotation around an axis parallel to the direction of travel of the apparatus, a plurality of vertical arms connected to the crossbars and extending downwardly therefrom for pivotally supporting axles for rotation around axles perpendicular to the direction of travel, and a wheel mounted on the outer end of each axle, whereby the wheels are caused to wobble as they are drawn over a gravel shoulder to effect efficient compacting of the gravel.
