  • Livestock feeder
    Patent number: 4574740
    Abstract: A livestock feeder for hay bales, stacks and the like comprising fence-like sides and ends hinged to each other at their ends and pivotally supported on posts centrally secured to the ends, to permit movement from a normal rectangular configuration to one of a parallelogram with the side sections closer to each other. Such a construction permits animals feeding along the sides of the feeder, to have access to feed in the center of the feeder as they bear against the sides thereby collapsing them inwardly.
