Road shoulder compacting apparatus
First Claim
1. A road shoulder compacting apparatus, comprising:
- a rotatable ground engagement member for rolling compacting engagement with the ground;
said ground engagement member having an axle;
a support structure for supporting said ground engagement member on a vehicle;
a raising and lowering structure for raising and lowering said support structure relative to the vehicle;
a support arm;
a first pivotal connection between one end of said support arm and said support structure, said first pivotal connection having a substantially vertical axis of pivotation and allowing pivotation of said support arm through an angle of 180°
between end positions in which said support arm extends transversely of the apparatus;
a second pivotal connection between the opposite end of said support arm and said axle, said second pivotal connection having a substantially horizontal axis of pivotation; and
a hydraulic actuator for pivoting said ground engagement member about said second axis of pivotation relative to said support arm;
said hydraulic actuator being mounted on said support arm for movement therewith; and
said support arm having a length sufficient to locate said ground engagement member at a lateral spacing from said support structure, on pivotation of said support arm into its end positions, for compacting a road shoulder.

Abstract
In a vehicle equipped with a road shoulder compacting apparatus, the apparatus includes a ground engagement member for rolling engagement with a shoulder of a road as the vehicle travels along the road, and a support structure carrying the ground engagement member on the vehicle and including an adjustable connection between the vehicle and the ground engagement member. The adjustable connection permits displacement of the ground engagement member from one side to the other of the vehicle and vice versa, so that the ground engagement member can be utilized at opposite sides of the vehicle. A selectively adjustable mechanism is provided for raising and lowering the ground engagement member into and out of engagement with the ground.
