<p>A method and an apparatus for linearly conveying wheeled vehicles are disclosed wherein at least one wheel of the vehicle is supported by a plate which reciprocates longitudinally through a forward stroke and a reverse stroke. The supported wheel is engaged and blocked to prevent its rotation during the forward stroke, thereby pushing the wheel, and thus the vehicle, to a forward position with the plate. During the reverse stroke, the wheel is free to rotate, permitting the plate to return to its rearmost position while the wheel remains at the forward position. During subsequent forward strokes, the wheel is similarly engaged and blocked and the vehicle is sequentially advanced the length of the forward stroke during each reciprocation of the plate.</p> |
