  • Patent number: 5339767
    Abstract: A bird feeder including a pipe having a hollow interior for holding a supply of bird feed. The lower end of the pipe is embedded in the ground. The upper end of the pipe is opened. A coil spring is positioned within the pipe. Support structure is provided for supporting the lower end of the coil spring. A plunger is slidably positioned within the pipe and positioned on the upper end of the coil spring. A cable extends from the plunger to a point below the coil spring. A winch is attached to the end of the cable opposite the plunger for pulling the plunger downwardly to compress the coil spring. A rigid platform is attached to and encircles the open upper end of the pipe. The open upper end of the pipe is closed by a cover that keeps the bird feed within the pipe under tension while allowing birds to pick bird feed therefrom and while preventing bird feed from freely passing out the open upper end of the pipe.
