Abstract

A squirrel repelling hanger for a bird feeder which utilizes a load cell which senses the weight of a squirrel thereon and which energizes a motor to rotate a repelling disk located at the upper end of the hanger without rotating the bird feeder which is supported from the lower end of the hanger.

Claims (8)

1. A squirrel repelling hanger assembly for a bird feeder, comprising:

a first support having upper and lower ends;

said lower end of said first support being mechanically connected to a load cell which is electrically connected to an electrical circuit;

a second support operatively connected to said load cell for supporting a bird feeder;

a repelling disk rotatably mounted above said load cell and being rotatable with respect thereto and with respect to said first support;

a motor electrically connected to the electrical circuit and mechanically connected to said repelling disk which rotates said disk without rotating said second support and bird feeder when the weight of an undesirable animal upon said disk causes said load cell to activate said motor through the electrical circuit.

2. The structure of claim 1 wherein said disk has openings to allow air to pass therethrough.

3. The structure of claim 1 wherein said first and second supports means are hooks.
