Title: Animal watering device
IPC: A01K39/02
Filed: 1965-01-16
Abstract: Watering device for livestock includes a valve in the form of a resilient flexible tube which is caused to be kinked back on itself to shut off the flow. As shown, the pan 10 is carried by a bracket 31 hinged at 34 to a support 14, 18, 19. A supply pipe 12 is connected to the pan through the tube 38. A pressure member 33 forming part of a balance arm on the bracket 31, presses the tube toward an abutment 41 on the support when the pan is lowered, thereby kinking the tube at 39 to shut off the flow. In another embodiment, Figs. 5 and 6 (not shown) the pan is suspended vertically on a rod which passes upwardly into a valve housing and carries a pressure plate. This plate engages the free bent back end of a flexible tube. The rod is spring urged upwardly normally to kink the tube and stop flow.
