Abstract

A game table wherein the cushion rails are replaceable and held in operating position with right angular corner engagement by means of hidden hold-down fasteners adjustably removable through the slate and overlying cover. The cushion rail is provided with a downwardly facing undercut groove while the upper surface of the rail is imperforate. The marginal portion of the table surface is provided with a plurality of spaced, vertically extending apertures. The head portion of a plurality of bolts is placed within the grooves such that the bolts will not be disengaged from the rail when the bolts are moved in a perpendicular direction away from the rail; the bolts are then inserted into the apertures in the table surface and thereafter, threaded nuts are placed on the lower end of the bolts for tightly securing the rail to the table surface.
