  • Freeze resistant adjustable flow rate animal nipple waterer
    Patent number: 4819585
    Abstract: A nipple type animal watering device is disclosed having an adjustable flowrate, and freeze protection. The flow is adjusted by a screwdriver depression and turning the trigger and without removing or disassembling the nipple. The freeze protection is due to the nipple/trigger relationship and the selection of materials for the nipple and valve body such that a warmer valvebody is easier to maintain.
