Abstract
A ground-supported poultry drinking fountain utilizing a bell-shaped member having an annular trough. A massive ground support member is disposed within the interior of the bell-shaped member, and connecting rods extend through the bell-shaped member to rigidly connect the massive support member to a valve-supporting member. Adjustments are provided for adjusting the effective length of the rod and therefore the height of the trough off the ground. A valve for supplying water to the trough is supported by the valve support member, and a spring is provided to suspend the bell-shaped member from the valve support member independent of the connecting rods so that the annular trough will reciprocate vertically under the influence of the spring depending upon the amount of water in the trough. Force-concentrating surface manifestations and/or an extremely massive bottom can be provided with the support member to ensure that the fountain stays immobile with respect to the ground.
