Abstract

A ball cock and float assembly (10) having a shank portion (11) that is adapted to be insertably received through the inlet opening (13) in the bottom wall (14) of a reservoir tank (12). A support means (50) extends upwardly of the shank portion (11). The support means (50) comprises post means (30) that extend fixedly upwardly from the shank portion (11), and extension means (46) that are telescopically slidable along the post means (30). A lock (42) secures the extension means (46) at a selected position along the post means (30) to provide in gross adjustment in the vertical height of the float assembly (110) that is movable along the extension means (46). A valve (55) is carried by the extension means (46) upwardly of the float means (110). An inlet conduit (52) communicates from the shank portion (11) through the post and extension means (30, 46) to the inlet port ( 54) of the valve means (55). A discharge conduit (53) communicates from the outlet port (62) of the valve (55) through the support means (50) and opens (at 40) into the reservoir tank (12). A siphon-break chamber (60) communicates between the discharge conduit (53) and atmopshere, and a lever (150) actuates the valve (55) in response to vertical movement of the float assembly (110). The lever (150) is connected to the float assembly (110) by an adjusting means (136, 144) that permits fine adjustment in the vertical height of the float assembly (110).
