ABSTRACT:
A two piece table leaf slide support consisting of a U-shaped metal channel member and a metal support bracket slidably supporting the channel member, the elongated U-shaped channel member having a vertical base wall, and a top flange and a bottom flange extending longitudinally orthogonally of the base wall, one end of the channel being curved with the top and bottom flanges remaining substantially in their respective planes, and a pair of lengthwise spaced apart lancings through the channel member vertical base wall effective to prevent the channel member from jamming or shifting endwise out of the support bracket. The support bracket has a generally rectangular elongated bottom wall and a pair of parallel side walls extending upward from the long edges of the bottom wall and turning outward in plane in opposite directions at the upper edges of the side walls as a pair of top flanges, the top flanges including screw holes by which the bracket may be secured to the underside of a table, and a lancing through one of the sidewalls of the support bracket which extends inward into closely overlying relationship to the bottom flange of the U-shaped channel and is effective to retain the channel member in the bracket below the level of the top flanges.
