Abstract

A manual curbing device includes a box-shaped hopper with an open top and bottom. The hopper is for receiving asphalt concrete via the open top. A pair of skids is each attached to opposite sides of the bottom of the hopper on the exterior thereof. The bottom portion of the front of the hopper has an opening of predetermined size to permit the expulsion of the asphalt concrete by gravity. The device includes at least one flat thin removable interchangeable extrusion curb forming plate having an opening sized and shaped to form the cross-sectional size and shape of a curb to be extruded. A pair of L-shaped curb forming plate retaining brackets are operatively attached in predetermined position to opposite exterior sides of the hopper proximate the front thereof to form a slot for receiving the flat removable interchangeable extrusion curb forming plate. A rear handle is operably attached to the back of the hopper.

Claims

1. A manual curbing device comprising:

a box-shaped hopper with an open top and bottom, the box-shaped hopper for receiving asphalt concrete via the open top,

a pair of skids each attached to opposite sides of proximate the bottom of the hopper on the exterior thereof,

the bottom portion of the front of the hopper having an opening of predetermined size to permit the expulsion of the asphalt concrete by gravity,

at least one flat removable interchangeable extrusion curb forming plate having an opening sized and shaped to form the cross-sectional size and shape of a curb to be extruded,

a pair of L-shaped curb forming plate retaining brackets operatively attached predetermined position to opposite exterior sides of the hopper proximate the front thereof to form a slot for receiving the flat removable interchangeable extrusion curb forming plate, and,

a rear handle affixed to the back of the hopper.

2. The manual curbing device of claim 1, further comprising a front handle operatively attached to the upper portion of the front of the hopper.

3. The manual curbing device of claim 1, wherein each of the skids have an L-shaped cross-section.

4. The manual curbing device of claim 1, wherein each of the skids have an upward inclination at the front and rear end thereof.

5. The manual curbing device of claim 2, wherein the front handle is attached to the upper portion of the front of the hopper a predetermined distance below the top thereof.

6. The manual curbing device of claim 1, wherein each of the L-shaped curb forming retaining brackets is made of metal.

7. The manual curbing device of claim 1, wherein the bottom of each of the skids has a smooth surface.

8. The manual curbing device of claim 1, wherein the opening of the at least one flat removable interchangeable extrusion curb forming plate has an inverted U-shape.

9. The manual curbing device of claim 1, wherein the opening of the at least one flat removable interchangeable extrusion curb forming plate has an inverted V-shape.

10. The manual curbing device of claim 1, wherein the at least one flat removable interchangeable extrusion curb forming plate having a first upper wing portion extending beyond the opposite exterior sides of the hopper in the operative position, the first upper wing portion having a first plate grasping handle operatively attached and extending on opposites thereof, whereby the at least one flat removable interchangeable extrusion curb forming plate may be easily removed and replaced by another flat removable interchangeable extrusion curb forming plate.

11. The manual curbing device of claim 1, wherein each of the first plate grasping handles extend perpendicularly on opposite sides of the upper wing portion of the flat removable interchangeable extrusion curb forming plate.

12. The manual curbing device of claim 1, further comprising a flat removable solid plate without an opening, whereby the flat removable interchangeable extrusion curb forming plate can be removed from the slot and replaced with the flat removable solid plate without opening for permitting movement of the curbing device with hopper loaded with asphalt concrete without forming a curb.

13. The manual curbing device of claim 1, wherein the flat removable solid plate without an opening has a second upper wing portion extending beyond the opposite exterior sides of the hopper in the operative position, the second upper wing portion having a plate grasping handle operatively attached on opposite sides thereof.

14. The manual curbing device of claim 12, wherein each of the second plate grasping handles extend perpendicularly on opposite sides of the second upper wing portion of the flat removable solid plate.

15. The manual curbing device of claim 1, wherein the rear handle is U-shaped.

16. The manual curbing device of claim 2, wherein the front handle is U-shaped.
