Title: Reciprocating storage unit
IPC: B65G27/02
Filed: 1980-07-31
Abstract: A reciprocating storage unit 10 particularly adapted for moving and temporarily storing of component parts includes a drum assembly 200 providing a downward low-friction helical guide path between an upper entrance point 280 and a lower discharge point 282.
