Abstract: A novel adjustment mechanism is provided for varying the height of a poultry drinker above a poultry feeder. The adjustment mechanism preferably includes a first portion to which the feeder is attached, a second portion to which the drinker is attached, and a structure, such as a pin, for fixing the position of the second portion relative to the first portion. The first portion includes a slot along which the second portion slides. The second portion includes a support channel which extends through the slot and the fixing structure contacts the first portion and the support channel to prevent movement of the second portion relative to the first portion.

Abstract: A drinker, which is connected to a supply pipe, includes a novel attachment member that forces a bird's beak open during activation to deliver water directly into the bird's open beak so that the amount of water the bird receives is maximized. A pin is provided as a valve which selectively blocks or allows flow from the supply pipe to the attachment member. When a bird contacts the attachment member, the bird's beak is forced open and the attachment member substantially prevents contact of the beak with the water flowing through the attachment member, such that the water flows from the supply pipe, past the pin, through the attachment member, out an outlet on the attachment member and into the bird's open beak. A first embodiment of the attachment member includes a double-walled body member having inner and outer walls such that the water flows between the inner and outer walls. A second embodiment of the attachment member includes a single-walled body member.

Abstract: A watering system for poultry and other animals which includes a watering cup having side walls and an opening defined in a lower base portion, a valve body positioned within the watering cup and connected to a water supply manifold, coupling and sealing apparatus for fastening the valve body and the watering cup to the manifold in a water-tight manner, and a plunger assembly positioned within the valve body for selectably controlling a flow of water from the manifold through and out of the valve body. Most importantly, the invention further includes a deflector bell mounted on the plunger assembly for developing and channeling one or more water jets into the watering cup after the valve has been opened by the watering poultry. The water jets are developed and directed into the watering cup by grooves formed in the deflector surface confronting the water flow emerging from the valve body.
