ABSTRACT:
A novel poultry watering apparatus including a central support member suspended from a ceiling, from which watering apparatus including a feed pipe and a plurality of poultry watering cups is in turn suspended. Anti-roost apparatus is supported on a plurality of vertical stanchions extending above the central support member. An improved valve structure having an anti-clogging device disposed at the inlet opening thereto is also disclosed. The anti-clogging apparatus comprises a pin extending through the inlet opening having a diameter less that that of the opening, and which is spring-biased in a downward position. When the valve is opened by the poultry, water pressure from the feed pipe overcomes the spring pressure and allows water to flow through the opening. The flow of water agitates within the opening, thereby preventing accumulation of debris within the opening. A novel unitary structure, preferably made of plastic, for the poultry watering cup is disclosed. A threaded insert portion of the valve assembly mated directly with a threaded portion of a unitary plastic cup wherein the analogous structure was threaded into a seocnd separate structure in the prior art.
