ABSTRACT:
There is disclosed conveyor apparatus which provides for the interruption and subsequent re-establishment of driving engagement between the conveyor drive means and the conveyed articles. The conveyor employs a stationary frame having support surfaces adapted to have the conveyed articles supported thereon. In conjunction with the frame, there is disclosed drive means support structure which is movable relative to said frame. Accordingly, the drive means may be positioned above the frame support surfaces to provide driving engagement, or said drive means may be lowered to level which results in the conveyed articles resting upon the frame, with an interruption in said driving engagement. The preferred form of mounting means disclosed for said drive means support structure, includes a pressurized element, such that the relative movement of said support structure may be achieved in response to the weight of conveyed articles resting upon said support structure.
