Abstract: A book support is mounted to a vertical upright assembly affixed to a weighted base. The book support is selectively positionable in various horizontal positions by swinging a horizontal swing arm articulated with a pivot connection to a one end of a horizontally extending segment of an upper member of the upright assembly. The swing arm is also rotatable about its own axis longitudinal by a pivot connection with the horizontal segment of an upper member of the upright assembly. An adjustable pivot connection also mounts the book support to a free end of the swing arm allowing reorientation of the book support about an axis normal to the longitudinal axis of the swing arm. A book shelf-rack support structure is fitted over the upright and has book shelves, racks mounted thereto. A cast iron platform weights the base and has a molded plastic cover.

Abstract: An improved avian tower comprises a base to which is attached a substantially cylindrical center column which surrounds a central post, formed from a plurality of interdigitating column portions wherein each column portion includes a body, a first shoulder and a second shoulder whereby the first shoulder and second shoulder of adjoining column portions cooperate to allow configurable construction of the center column. A plurality of perches are attached to at least one of the plurality of column portions.

Abstract: A parrot tower having a plurality of removable orthopedic perches attached to a center column, the column being mounted atop a sterilizable tray. The entire unit is formed of plastic, such that it may be easily transported and assembled/disassembled. The perches are formed such that no perch extends beyond the edge of the tray thereof, thus preventing the spilling of seeds or droppings. A plurality of reinforcing ribs allows a center column to achieve a height of three feet without more than a few inches of the center column being deployed therewith in the tray.
