Abstract

Apparatus for slip-forming concrete to form a path comprising in combination a box having a front wall extending downwardly through the box, and a rear wall extending downwardly at an angle through the box to a location above the front wall, and opposing side walls coupling the front and rear walls extending downwardly to define the closed box having an upper opened end for receiving concrete and a lower opened end with a vertically disposed opened mouth defined by the vertical edges of the side walls and the lower edge of the rear wall, with the lower opened end having a smaller cross-sectional area than the upper opened end, and a screed for slip-forming the concrete, means for removably securing the screed at its edges to the side walls below the rear wall with the forward end of the screed being positioned at the opened mouth of the rear wall.

Claims

1. A paver for slip-forming a path of concrete onto a pathway the upper surface of which constitutes a plane of construction, comprising in combination:

a box having an exterior front wall and an interior front wall extending downwardly at an angle through the box to the plane of construction, and a 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 the plane of construction to define the closed box having an upper opened end for receiving concrete and a lower opened end with a vertically disposed opened mouth defined by the vertical edges of the side walls and the lower edge of the rear wall, with the lower opened end having a smaller cross-sectional area than the upper opened end;

a screed for forming the concrete, means for securing the screed at its edges to the side walls adjacent to the lower edge of the rear wall with the forward end of the screed being positioned at the opened mouth;

shoes removably positionable interiorly of the side walls and exteriorly of the screed to reduce the width of the path being formed;

a ski formed by the bends in the exterior front wall and secured at its edges to the side walls across the lowermost front edge of the box, the plate being angled to create a ski-like effect upon movement of the paver on the pathway;

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

fins extending downwardly from the box to stabilize the movement of the paver; and

hitch means connected to the front of the box allowing the paver to be connected immediately behind a cement truck by means of a chain such that concrete being dispensed from the chute of a cement truck pulling the apparatus flows into the upper opened end of the box while the screed forms the concrete from the opened mouth of the lower opened end into a concrete path laid directly on the pathway.

2. Apparatus for slip-forming concrete to form a path comprising in combination:

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

a screed for slip-forming the concrete, means for removably securing the screed at its edges to the side walls below the rear wall with the forward end of the screed being positioned at the opened mouth of the rear wall.

3. The apparatus as set forth in claim 2 wherein the box has an exterior front wall and an interior front wall defining a closed chamber therebetween.

4. The apparatus as set forth in claim 3 wherein the exterior front wall includes a ski formed by bends therein to create a ski-like effect upon movement of the paver on the pathway.

5. The apparatus as set forth in claim 2 and further including a pair of skids affixed to a lowermost edges of the sidewalls causing the box to float upon the pathway during movement of the paver.

6. The apparatus as set forth in claim 2 and further including fins extending downwardly from the box to stabilize the movement of the paver.

7. The apparatus as set forth in claim 2 and further including means to vary the curvature of the screed.
