Abstract

A pavement patcher has a frame supported on the back of a truck. An operator'"'"'s platform is movable horizontally and transversely on the frame across the back of the truck, and longitudinally for a short distance. The platform carries a hydraulic control console and a blacktop hopper with a hydraulic rotor and an auger. The platform also carries a steel roller mounted on hydraulic rams. The truck driver stops with the frame over a hole. The operator riding on the platform positions the side delivery opening at the bottom of the hopper next to the hole and operates the auger to dispense the required amount of blacktop. The operator then extends the rams to lower the roller and moves the platform to roll the roller across the patch. Significant force is developed on the roller from the hopper'"'"'s platform, carriage, frame and truck to seal the patch. A hydraulic package is mounted at a side of the frame with a motor, pump and reservoir.

Claims

1. A pavement patching apparatus comprising a frame for supporting on a back of a truck, and operator'"'"'s platform movably mounted on the frame, means for moving the platform horizontally across the frame between first and second sides of the truck parallel to the back, and moving transversely upwards and downwards along the back of the truck, and means for moving the platform longitudinally towards and away with respect to the back of the truck on the frame for a relatively shorter distance, an integrally formed hydraulic control console on the platform, an integrally formed blacktop hopper on the platform, a hydraulic rotor connected to the hopper and an auger connected to the hydraulic rotor and mounted within the hopper for moving the blacktop material through the hopper as the hydraulic rotor rotates, a side delivery opening at the bottom of the hopper for dispensing blacktop from the hopper to a pavement hole, a hydraulic roller mounted on the platform and extensible below the platform into contact with blacktop over the hole for pressing the blacktop into the hole under the pressure of the roller.

2. The apparatus of claim 1, wherein the frame has a mounting portion which is connected to the truck, and a platform portion which is mounted on an end of the truck-connecting portion and which extends generally horizontally below a plane of the truck bed.

3. The apparatus of claim 1, further comprising a shelf mounting the hydraulic package, including a pump and reservoir and motor mounted on one end of the platform portion of the frame along one edge of the truck.

4. The apparatus of claim 3, wherein the platform portion of the frame comprises first and second parallel rails, and first and second carriage means respectively mounted on the first and second rails.

5. The apparatus of claim 4, wherein the platform further comprises first and second slides having opposite ends connected to the first and second carriages for moving the spaced slides transversely across a back of the truck on the platform portion of the frame.

6. The apparatus of claim 5, wherein the platform is mounted on the slides on bearings for allowing forward and aft movement of the platform on the slides.

7. The apparatus of claim 6, wherein the platform includes an operator'"'"'s stand and wherein the hopper includes a vertical chute with an upper opening for receiving blacktop from a bed of the truck, and wherein the control console is mounted on an upper end of the chute, whereby the operators stand and the chute and the console move back and forth with the platform on the slides.

8. The apparatus of claim 7, wherein the chute has first and second parallel links with first ends connected to front and rear sides of the chute near a bottom thereof, and wherein the roller has an axle connected to second ends of the first and second links for pivoting on the links with respect to the lower end of the chute, and further comprising rams connected to the axle of the roller and to the platform for respectively lifting the roller away from pavement and forcing the roller toward the pavement against the downward pressure of the platform and frame and truck for sealing blacktop deposited in a pothole from the chute.

9. A method of filling potholes comprising filling a hopper from a truck bed, driving a truck into position where a pothole is in back of a truck, moving an integrally formed platform hopper and chute downwards transversely across and to or from a truck bed until the opening at a bottom of the chute is aligned with a pothole, releasing blacktop from the chute, lowering a roller into the surface of the blacktop and pressing the roller in the direction of the pavement, moving the roller, chute and platform simultaneously transversely with respect to the truck and sealing the blacktop in the pothole.

10. The method of claim 9, further comprising moving the platform hopper and chute longitudinally with respect to the truck on a frame.

11. A pavement patching apparatus comprising a frame for supporting on a back of a truck, a platform movably mounted on the frame, means for moving the platform horizontally between first and second lateral sides of the truck across the frame, transversely upwards and downwards along the back of the truck and longitudinally towards and away from the truck, an integrally formed hydraulic control console on the platform, an integrally formed patching material hopper on the platform, a rotor connected to the hopper and an auger connected to the rotor and mounted within the hopper for moving the material through the hopper as the rotor rotates, a delivery opening at the bottom of the hopper for dispensing from the hopper to a pavement hole, a compactor mounted on the platform and extensible below the platform into contact with material in the hole for pressing the material into the hole under the pressure of the compactor.
