Abstract
A material transfer machine includes a slat conveyor of substantially the width of a feed hopper of a paving machine. The slat conveyor is supported by caster wheels to be disposed at an incline having a material intake end at a lower end thereof and a discharge end at the opposite upper end of the conveyor. The slat conveyor is mounted to a leading edge of the paving machine such that the upper discharge end is disposed above the feed hopper of the paving machine. A hopper is disposed ahead of the lower intake end of the slat conveyor, supported by a frame which is pivotably attached at a rear end thereof along the sides of the slat conveyor to an understructure thereof. The front end of the frame is supported by caster wheels, such that the frame is capable of joint movement with the conveyor and the paving machine while supporting pivotal movement in a vertical plane in response to grade changes of a base grade. Material is transferred from beds of supply trucks by backing the trucks toward the leading edge of the hopper to align the rear of the beds with the hopper. The material is dumped into the hopper and is transferred by the slat conveyor directly from the hopper of the material transfer machine to the feed hopper of the paving machine without getting into contact with the base grade of the road being paved.
