and the upper conveyor 18 are not in alignment to cause material to move along a general direction of travel c c fig4 is a partial side view of the lower conveyor 16 and upper conveyor 18 in the view shown in fig4 the pivot axis b b is illustrated as a pivot point 80 the upper conveyor 18 pivot from side to side along one the slew axis a a with respect to the lower conveyor 16 this permits the upper conveyor 18 to move material either along the direction defined by the longitudinal direction of lower conveyor 16 or the material may turn when the material enters the upper conveyor 18 and move in a direction out of alignment with the longitudinal direction of lower conveyor 16 depending upon the pivotal direction of the upper conveyor 18 as that pivots about axis a a the upper conveyor 18 can also pivot with respect to pivot point 80 as shown in fig4 or in other words about axis b b as shown in fig3 and 5 this elevation pivoting allows the discharge and 78 of the upper conveyor 18 to be raised or lowered as needed as illustrated in fig4 through 5 the axes a a and b b intersect at the upper conveyor 18 near the transition zone 62 because these two axes a a and b b intersect each other they define.
