发明名称 Slate leveling system for a billiard table
摘要 Time consuming, unreliable leveling of the playing surface of a billiard table is eliminated in a billiard table including a base frame (10) adapted to be supported above the underlying terrain by legs. The base frame has an upper top plate (12) of generally rectangular configuration and a slate bed made up of at least two slate sheets (24) with planar upper surfaces (26) disposed in a generally side by side abutting relation overlying the top plate (12). A plurality of nuts (52) are secured to the top plate (12) at predetermined locations thereon and a plurality of leveling screws (62) are provided, one for each nut (52). Each leveling screw includes a threaded shank (62) received in the associated nut (52) in a radially outwardly directed flange (64) at one end of the shank at the interface of the top plate (12) and the slate sheets (24) and engaging one of the slate sheets (24). Through rotation of the leveling screws (62), the corresponding slate sheet (24) may be selectively raised, lowered or tipped to cause the planar surfaces (26) to be co-planar in a perfectly horizontal plane.
