  • Liquid level control
    Patent number: 4254311
    Abstract: A liquid level control wherein a receptacle for collecting liquid is carried on a support for movement in accordance with the weight of the liquid collected therein. A switch is mounted adjacent the receptacle so as to be actuated as an incident of movement of the receptacle. A control is provided which is adjustably retained on the support adjacent the receptacle to provide a selectively adjustable resistance to movement of the receptacle whereby the weight of the collected liquid necessary to actuate the switch may be selectively adjusted. The control is arranged to be fail-safe in that should the control loosen, actuation of the switch is effected by a minimum weight of collected liquid in the receptacle.
