Abstract
Abstract A turn-table for supporting a flat game board, the turn-table including a base portion which rests on a table or the like and a flat platform portion, pivotally supported on the base portion, and provided with a pair of spring clamps, one at each end of the platform, for engaging edge areas of the game board to hold the board securely on the platform. Adjustment of the clamp spacing to fit boards of different sizes can be effected either by relative movement of the parts of a two-piece platform or by relative movement of elongated clamps on the ends of a one-piece platform.
