Image Number 6 for United States Patent #6526916.
A portable, pet-actuated drinking fountain includes a reservoir container received in a housing and a movable platform which is depressed against a spring when a pet steps on it. Downward movement of the platform by the pet closes a switch that connects battery power to a pump that provides a gentle bubbling of water from the container via a vertical spigot reachable by the pet. Excess water drains back into the reservoir container through a filter screen. When the pet steps back off the movable platform, the pump is deactivated. One or more movable platforms may be associated with a single reservoir container and arrange to actuate the pump.
