    • A cart may comprise a body, an axle having an axis of rotation, at least one wheel, a forward support, and a rear support. The forward support may include a forward support hinged end, and a forward support free end, the forward support hingedly connected to the body at the forward support hinged end to pivot about a forward support axis. The rear support may include a rear support hinged end, and a rear support free end, the rear support hingedly connected to the body at the rear support hinged end to pivot about a rear support axis. The forward support free end may be configured to selectively connect to the rear support at the rear support free end by the axle to rotatably support the wheel, and the axis of rotation of the axle may be parallel to each of the forward support axis and the rear support axis.

    • An automatic animal watering apparatus includes a dish having an automatic watering valve disposed therein. When the valve is first closed, a water level in the dish is at a maximum level, and a hydraulic source pressure acts only across a smaller cross-sectional area of a valve seat which is closed by the valve, thus requiring only a first lower buoyancy force acting on a valve actuator float to maintain the valve closed. The water level can then drop from the maximum water level to a minimum water level before the hydraulic force action on the valve overcomes the first lower buoyancy force on the actuator float and reopens the valve. Then when the valve opens, the hydraulic source pressure acts against a larger cross-sectional area of the valve, thus requiring the buoyancy forces acting on the float to rise to a second higher buoyancy force to reclose the valve. The automatic watering device may be mounted on an external structure through the use of a mounting bracket, and removable mounting pins may connect the dish, the mounting bracket and a cover plate of the dish.
