Abstract
A poultry drinker includes a headless bell with a replaceable cartridge assembly for operatively attaching the bell to a conventional valve and a stand or a ballast. A flat annular support surface at the headless top of the bell cooperates with an annular support surface of the cartridge assembly, and a nut engages external threads on a tubular body of the cartridge assembly to clamp the bell annular support between itself and the cartridge annular support. An internal shelf in the cartridge to operate the valve, water passage openings are formed in the tube above the shelf, and the tubular body is connected to the valve by threads or the like. A flange radially extending from the cartridge adjacent the cartridge annular support is received by a cutout in the bell annular support to prevent rotation between the bell and cartridge. A screw-threaded post operatively attached to the shelf and extending through the cartridge annular support member provides attachment to the stand or ballast member.
