ABSTRACT:
The high cycle rate transfer device invention disclosed herein enables a continuous conveyance of material in a limited space envelope. Particularly, a roller chain is driven by a center sprocket with outboard rollers on the chain running in a track so that material can be moved in both directions. Pawls on each end of the chain are used to urge the material. Each time the chain is moved, a pawl folding and unfolding mechanism maintains the pawls in a proper position and timed relation to each other.
