Abstract
Abstract An adjustable pedestal adapted to support individually removable panel members in accurate, edge-aligned relation and in a common horizontal, that is level plane. The pedestal includes a head assembly supported on an upper end of a support. The head assembly includes a head member having a generally flat upper surface which is adjustable vertically, rotationally and laterally of the support rod. Abutment means adjustable along the support rod, is engaged by the head member and establishes a position of the head member wherein the upper surface resides in the horizontal plane. Clamping means clamps the head member to the support rod. Radially extending lugs extend above the upper surface of the head member. The arrangement is such that an adjacent pair of lugs of one pedestal cooperates with adjacent pairs of lugs from adjacent pedestals to define a panel supporting surface which is horizontal and which coincides with said horizontal plane.
