ABSTRACT:
The concrete path paver of the invention comprises a generally rectangular open-ended box having a front wall and an inwardly sloped rear wall rigidly connected between a pair of side walls to define a bottom opening. An adjustable screed is positioned underneath the sloped rear wall from the rearward side of the bottom opening and extends a significant distance beyond the lower edge of the rear wall to form a slip-form mold. A platform is affixed rearwardly of the rear wall above the screed allowing an operator to stand thereon and control the flow of concrete from the cement truck into the box. The concrete path paver further comprises an arcuate or flat plate affixed to the lower front edge of the front wall of the box. The front plate functions as a ski to push and smooth dirt along the path that may have been disrupted by the tires of the cement truck. Thus, the tire tracks made by the cement truck as it pulls the paver are filled in and smoothed over prior to the concrete being laid. Further, the concrete path paver includes a pair of skids affixed along the lower edges of the sides to prevent the edges from digging into the dirt during pulling of the box.
