210 may move relative to the location of the auxiliary conveyor 200 currently operators need to make various adjustments in order to try to accommodate such movement this can result in difficulty maintaining conveyor operation in order to accommodate some movement of the conveyor apparatus 210 relative to the auxiliary conveyor 200 the conveyor apparatus frame accommodates sliding movement at both ends at one end the sliding movement adjusts the tension of the conveyor 16 and sliding movement at the other end accommodates movement of the conveyor apparatus 210 relative to the auxiliary conveyor 200 if the conveyor apparatus 210 moves relative to the auxiliary conveyor 200 an operator can move the sliding end of the conveyor 210 adjacent the auxiliary conveyor 200 movement of the sliding end of the conveyor 210 can also be occasioned by the use of tensioning means as described hereinafter as used on the tensioning end 51 of the conveyor 16 only in this instance the movement is not intended to affect the tension of the conveyor 16 but the location of the end of the conveyor apparatus 210 relative to the auxiliary conveyor 200 when movement at this end of the conveyor occurs the chain tension does change so the other end of the conveyor apparatus 210 is adjusted by the automatic tensioning means to return the conveyor 16 back to the appropriate tension movement of the sliding end of the conveyor 210 adjacent to the auxiliary conveyor.
