ABSTRACT:
An energy free animal waterer of a type having an insulated container for holding water, a supply conduit for supplying water under pressure to the container and a valve connected to the supply conduit for maintaining the water in the container substantially at a predetermined level. An insulated lid is sealingly attached to the top of the container and has a pair of openings therein each large enough to permit an animal to extend its mouth therethrough for the purpose of drinking water from the container. A first closure is disposed within the container below the lid for selectively sealingly closing the first opening and a second closure is disposed within the container, below the lid for selectively sealingly closing the second opening. A flexible length member extends between and is rotatably attached to the first and second closure members at each end of the length. Biasing structure, preferably a cable extending over a pulley and having a weight attached to one end thereof and the other end attached to an intermediate part of the link member, holds the closure members against the bottom of the first and second openings to keep them closed except when an animal is pushing them down to drink from the container.
