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.

Claims

1. A concrete path paver for slip forming a slab of concrete onto a dirt pathway, the upper surface of the dirt pathway constituting a plane of construction, comprising in combination:

a box having a front wall extending downwardly at an angle through the box to the plane of construction, and an inwardly sloping rear wall extending downwardly at an angle through the box to a location above the plane of construction, and opposing side walls coupling the front and rear walls extending downwardly to at least the plane of construction to define a closed box having only an upper opened end for receiving concrete and a lower opened end with a vertically disposed opened mouth defined by the vertical edges of said side walls and the lower horizontal edge of said rear wall, with said lower opened end having a smaller cross-sectional area than said upper opened end;

a fixed screed for slip forming the concrete, means for securing said screed at its edges to said side walls below said rear wall with a mouth of said screen being positioned about said opened mouth of said rear wall;

a plate secured at its edges to said side walls across a lowermost front edge of said box, said plate being upwardly turned to create a ski-like effect upon movement of the paver on the pathway;

a pair of skids affixed to a lowermost edge of said sidewalls of said box causing said box to float upon the pathway during movement of the paver; and

hitch means connected relative to said front of said box allowing the paver to be connected immediately behind a cement truck by means of a chain or like such that concrete being dispensed from the chute of the cement truck flows into said upper opened end of said box to fill the same while said screed slip-forms the concrete from said opened mouth of said lower opened end into a concrete slab laid directly on the pathway.

2. The concrete path paver as set forth in claim 1, wherein said screed comprises an upturned front edge for mating engagement with a lower edge of said inwardly sloping rear wall.

3. The concrete path paver as set forth in claim 2, further comprising means for adjusting the vertical height of said screed relative to said mouth of said lower opened end allowing a slab of concrete of a desired thickness to be slip-formed.

4. The concrete path paver as set forth in claim 3, wherein said adjustment means comprises a pair of upturned side flanges extending from opposing sides of said horizontal member, each said side flange including a slot for receiving a threaded fastener from said side walls therethrough for secure adjustable connection of said upturned side flanges to said side walls.

5. The concrete path paver as set forth in claim 4, further comprising a vibrator for vibrating said rear wall of said box.

6. The concrete path paver as set forth in claim 4, further comprising a platform extending horizontally across the rear of said box by means of a bracket affixed to said box.

7. The concrete path paver as set forth in claim 4, wherein said front wall is inwardly sloped.

8. The concrete path paver as set forth in claim 5, further including a plurality of vertically disposed reinforcements extending from said plate and said skids to increase the strength thereof.

9. The concrete path paver as set forth in claim 6, wherein said screed extends substantially between said opposing side walls.

10. The concrete path paver as set forth in claim 7, wherein said plate extends beyond said opposing side walls of said box over a forwardmost edge of said skids.
