ABSTRACT:
A multiple-shelved unit is disclosed, the unit being adapted for use in greenhouses, for supporting growing plants on the shelves thereof, the unit including a horizontal hollow shaft mounted for rotation and means for rotating the same, hub members carried by the shaft adjacent the ends thereof with each hub member supporting a plurality of radially-projecting hollow spokes and hollow elements carried by the spokes adjacent the outer ends thereof for pivotally supporting the shelves. The unit additionally includes means for connecting the hollow interior of said shaft to a water supply, means for providing water communication between the interior of said shaft and the interiors of the spokes supported by at least one of said hubs, and means for providing water communication between the lastmentioned spokes and the shelves whereby the plants supported by the shelves may be watered at desired intervals. A second similar unit may be employed with its hollow shaft in alignment with and connected to the hollow shaft of the first unit for rotation therewith, the connection in such case including valved means for the passage of water from the shaft of the first unit to the shaft of the second unit. An additional feature is the construction of the hub members which provides both a threaded and clamped connection with the spokes for insurance against the breaking of such connection.
