ABSTRACT:
A suspension-type poultry drinking fountain comprises a bowl supported in suspension and containing a water trough for receiving water to be made available for drinking by the poultry, and a valve assembly controlled by the weight of the bowl to maintain a predetermined level of water in the trough. For prefixing the level of the water to be maintained in the trough, the valve assembly includes a rotatable member having a plurality of projections circumferentially spaced around its outer periphery and releasably engageable with a retainer member fixedly carried by the drinking fountain to releasably retain the rotatable member in a preselected rotary position against unintentional rotation, but permitting forceful intentional rotation in order to change the water level in a convenient manner without disassembling the drinking fountain or its valve assembly.
