Road compacting apparatus
First Claim
1. A road compacting apparatus comprising main frame means for connection to a towing vehicle in spaced apart relationship thereto;
- bifurcated, fixed arm means extending horizontally rearwardly from said frame means for movement therewith;
pivot arm means pivotally mounted in said fixed arm means for limited rotation around an axis between the ends of the pivot arm means and perpendicular to the direction of travel of the apparatus during normal use;
crossbar means pivotally connected to each end of said pivot arm means for limited rotation around parallel to the direction of travel of the apparatus;
a plurality of separate spaced apart, vertical wheel arm means extending downwardly from each said crossbar means;
axle means pivotally connected to the bottom end of each said wheel arm means for limited rotation around an axis perpendicular to the direction of travel of the apparatus; and
wheel means mounted on said axle means, whereby because of pivoting of said pivot arm means, said crossbar means and said axle means, said wheel means are caused to wobble longitudinally and transversely of the apparatus for compacting a road.

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.
