Abstract
A conveyor comprising a first conveyor section and a second conveyor section which can be pivoted from a first position where it is in alignment with the first conveyor section to a second position where it is at an inclined angle with respect to the first conveyor section. A shaft pivotally connects the adjacent ends of the two conveyor sections together, and a spindle or pulley is journaled on the shaft and supports an endless belt in travel in a conveying run and a return run on the conveyor sections. A slide is mounted for sliding movement on each side rail of the first conveyor section and each slide carries a hold down roller which rides against the side edge of the upper working surface of the belt and hold the belt tangent to both the first and second conveyor sections. Each slide is also provided with a rack which is engaged with a gear that is fixed to the second conveyor section and is positioned concentrically of the pivot shaft. As the second conveyor section is pivoted relative to the first conveyor section, rotation of the gear moves the rack and slide plate move linearly to thereby change the position of the hold down roller relative to the spindle, thus maintaining…
