Abstract:
1. In combination with a conveyor, having upper and lower ends, supported by a framework including an elongated transversely extending axle having a first support wheel rotatably mounted at one end thereof and a second support wheel rotatably mounted on the other end, comprising: a first support, having an upper end, a lower end, a forward end and a rearward end, is selectively removably attached to the axle of the conveyor framework between the first and second support wheels; a second elongated support having forward and rearward ends; said forward end of said second support being pivotally secured, about a horizontal axis which is parallel to the longitudinal axis of the axle of the conveyor framework, to said first support; said second support having a rotatable drive axle rotatably mounted thereon with the drive axle being parallel to the axle of the conveyor framework; at least one drive wheel operatively connected to said drive axle for rotation therewith; a reversible power means mounted on said second support which is operatively coupled to said drive axle whereby said at least one drive wheel on said drive axle may be driven in either a forward or reverse direction; a length adjustable jack having forward and rearward ends; said length adjustable jack being extendable and retractable; said forward end of said jack being operatively pivotally secured to said first support about a horizontal axis; said rearward end of said jack being pivotally secured to said second support about a horizontal axis; the extension of said jack causing said at least one drive wheel on said drive axle to be lowered into a ground engaging position and whereby further extension of said jack applies downward pressure to said at least one drive wheel on said drive axle to increase the traction thereof with the retraction of said jack causing said at least one drive wheel on said drive axle to be raised relative to the conveyor framework axle to a transport position.
