  • Patent number: 5421290
    Abstract: An animal feeder includes a hopper suspended from a frame using a winch. The frame includes an A-shaped support member connected to a pair of feet. The hopper includes a drum having a removable lid and a bottom. The bottom of the drum includes an outlet which permits the dispensing of feed. Legs are connected to the bottom portion of the drum to support it on the ground and prevent the outlet from clogging. A solenoid operated gate controlled by an interval timer regulates the flow of feed from the hopper to produce periodic feedings. A brace connects to the upper portion of the drum to permit the suspension of the drum from the frame by the winch. The winch operates to lower the hopper to permit its easy filling with feed and to raise the hopper after it has been filled to suspend it from the frame. A chain connected between the hook and the bottom portion of the drum elevates the bottom portion of the drum to provide the hopper with an angled orientation with respect to ground.
