Abstract: A watering cup has a rear wall, shaped as by ledges, to direct water downwardly into the cup in a swirling motion. A triggering arm is mounted on the cup for pivoting in accordance with the operation of the arm by the fowl. A valve disposed in the cup is operative between a normally closed position and an open position in accordance with the triggering of the arm by the fowl. Water passing through the valve is directed in a swirling movement along the rear wall of the cup to clean the rear wall. This may be accomplished by hooded portions with configurations defining converging arcuate areas at their centers and outwardly and downwardly directed channels at their peripheries. The cup has a body portion and a clamping member. The clamping member may be coupled at one end to a pipe for supplying water to the cup and is provided at the other end with fingers for retention by the opposite lateral ends of the body portion.

Abstract: A valve disposed in a cup is operative between a normally closed position and an open position in accordance with the triggering of a triggering arm pivotally operated in the cup by fowl. The watering cup is formed from a body portion and a clamping member coupled to a pipe at one end for supplying water to the cup. The clamping member has fingers at the other end for retention by the body portion. A pivot pin is disposed on the rim of the body portion and pivotably supports the triggering arm. A rocker arm is also pivotable with the pin at a position internal to the body portion of the cup and adjacent to the inner wall of the cup. The pivotal movement of the rocker and triggering arms is limited in one direction by raised portions or detents on the inner wall of the cup. A gutter extends downwardly and outwardly from a position near the top of the cup to define a channel for directing from the cup water overflowing from the cup.
