ABSTRACT:
This invention comprises an assembly (10) for controlling the level (64) of fluid, such as water (14), in a container (11), which invention includes a source of supply (29) for discharging the water (14) into the container (11), a valve (21) connected to the water source (29), a float (23) pivotally connected to the valve (21) for holding said valve (23) open or closed, depending upon the level of fluid in the container (11); the assembly (10) comprising a bracket (31) pivotally mounted within the container (11) and fastened to the valve (21) and float (23) as a unit, and a shaft (57) and screw (49) combination seated in a wall (33) of the container (11), with one end of the screw (49) non-rotatably mounted in the bracket (31), the shaft (57) manually rotatable from external the container (11) which rotation results in longitudinal movement of the screw (49) relative to the shaft (57), thereby pivoting the bracket (31) upwardly or downwardly in the container (11), resulting in varying very slightly--or more as the case may be, the position of the float (23) and thus varying accordingly the opening or closing of the valve (21) and the level (64) of water (14) within the container (11).
