Abstract: A reciprocating storage unit particularly adapted for moving and storing of component parts used, for example, in mechanical-related apparatus includes a circular body providing a downward low-friction spiral guide path between an upper entrance point and a lower discharge point. A slope of the downward path is such that as parts enter the path, movement will not occur by gravity alone. To obtain movement, the unit reciprocates about its vertical axis which with gravity produces movement of each part in series of intermittent steps. Each part proceeds downward and may be stored in the unit in a damage-resistant manner adjacent to the discharge point for release as required.
