First Claim
1. A mobile, self propelled pothole patching machine comprising:
- a vehicle frame;
ground wheels for transportation of the vehicle frame across the ground to a pothole to be patched;
a hopper mounted on the frame for transporting a filler material for use in the patching;
a conveyor mounted on the vehicle frame for receiving the filler material from the hopper and for transporting the material to the pothole;
and apparatus for laying the material in the pothole comprising;
a roller;
a rake;
means mounting the roller and the rake on the vehicle frame for transitional movement relative thereto in a horizontal plane to effect raking and rolling of the material;
first lifting means for lifting the roller;
and second lifting means for lifting the rake relative to the roller.

Abstract
A mobile pothole patching machine comprises a vehicle frame which carries a hopper for receiving a filler material for the pothole. Underneath the vehicle is mounted a belt conveyor which can be moved back and forth longitudinally of the vehicle and can be pivoted side to side about a vertical axis. At a front of the conveyor is mounted a laying apparatus including a roller and a rake. The rake can be raised relative to the roller and both can be raised relative to the ground by a lifting apparatus attached to the conveyor. A fabric wiper carries an anti-sticking agent draped over the top of the roller. A blow heater is mounted on the laying apparatus and has a pipe directing heated air into the potholes. In front of the rake is mounted an air jet and a bonding agent jet for cleaning and bonding the pothole. The hopper includes a pair of cover plates which can be pivoted out to the sides on two links. The material from the hopper is conveyed by an auger flight with a canopy over the auger flight which can be moved longitudinally to support the weight of the filler material when the hopper is filled and to release the filler material to the auger flight.

18. A mobile, self-propelled pot-hole patching machine comprising:
-
a vehicle frame; ground wheels for transportation of the vehicle frame across the ground to a pothole to be patched; a hopper mounted on the frame for transporting a filler material for use in the patching; a conveyor mounted on the vehicle frame for receiving the filler material from the hopper and for transporting the material to the pothole; apparatus for laying the material in the pothole including a roller for rolling the filler material; and means for applying an anti-sticking agent to the roller to prevent bonding of the filler material to the roller; the applying means comprising a fabric member engaged over an upper part of the roller for wiping the anti-stick agent onto the roller and means for feeding the anti-stick agent onto the fabric member in a liquid form; wherein the fabric member has a width substantially equal to the roller, two ends supported above the roller and a center portion draped over the roller around a part of the periphery thereof. - View Dependent Claims (19)

20. A mobile, self-propelled pothole patching machine comprising:
-
a vehicle frame; ground wheels for transportation of the vehicle frame across the ground to a pothole to be patched; a hopper mounted on the frame for transporting a filler material for use in the patching; a conveyor mounted on the vehicle frame for receiving the filler material from the hopper and for transporting the material to the pothole; and apparatus for laying the material in the pothole; wherein the hopper includes an elongate base with side walls converging to the base and wherein the conveyor includes an auger flight mounted along the base for rotation about a horizontal axis longitudinal of the base, an opening at one end of the base through which the auger flight extends for transporting the material from the base through the opening, and a canopy mounted in the hopper adjacent the base over the auger flight and means for moving the canopy longitudinally of the base from a first position covering at least a part of the auger flight to a retracted second position exposing substantially the whole of the auger flight to the filler material in the hopper. - View Dependent Claims (21, 22, 23)
