Abstract

A device for spreading asphalt and other road paving materials is disclosed. The spreader comprises a main body, two separately adjustable wings and various end components to adapt the spreader to different road surfaces, tasks or operator preferences. Structural rigidity and strength results from the use of a three point hitch and a combination of three horizontal, longitudinally position pipes in the main body and three like positioned pipes attached to the wings, said pipes moving coaxially within the main body pipes.

Claims

1. A spreader apparatus to be towed by a traction device comprising:

a main body section having forward and rear blade surfaces,

at least three pipes longitudinally mounted in a horizontal manner within the main body,

two wings moveably mounted over said main body section, said wings having forward and rear blade surfaces,

at least three pipes longitudinally mounted in a horizontal manner within each of said wings, said pipes positioned to slide coaxially within the main body pipes when the wings are mounted on the main body,

two independently operable hydraulic cylinders mounted within the main body and wings with one end of each hydraulic cylinder attached to the main body and the other end of each hydraulic cylinder attached to each wing, said hydraulic cylinders connected to a system to operatively move the wings across the outer surface of the main body,

a second set of independently operable hydraulic cylinders each vertically mounted at the outer end of each of the wings,

end components moveably mounted to the outer ends of the wings and then secured to the tops of the vertically mounted hydraulic cylinders, said components moveable in a vertical direction,

said second set of hydraulic cylinders connected to a system to operatively move the end components in a vertical direction.

2. The spreader of claim 1 wherein the main body pipes are arranged in a triangular configuration.

3. The spreader of claim 1 wherein the end components are chosen from the group consisting of skis, side rollers and spreder box sides.

4. The spreader of claim 3 wherein the skis have wheels attached thereto.

5. The spreader of claim 1 having a three point hitch securely mounted to the front top thereof.
