Abstract
A rodent repelling bird feeder having an elongated vertical hanging support, a motor and a rotatable dish coupled to the motor. The motor is reciprocatively mounted in a motor sleeve so when a rodent of excessive weight alights upon the dish the motor is pushed against a resistive spring and a switch is closed, thereby engaging the motor which rotates the dish to dislodge the rodent therefrom.
Claims27
A squirrel repelling hanger assembly for a bird feeder comprising:
- an elongated rod having upper and lower ends, said upper end of said rod having a support means thereon, said lower end of said rod having a support means for supporting a bird feeder;
- a motor sleeve having a base and side walls projecting perpendicular from said base, said elongated rod being secured to the center of said base of said motor sleeve;
- a motor having first and second ends, a hollow output shaft and housing, said motor having an elongated opening extending from said first end to said second end of said motor;
- said motor being mounted in said motor sleeve for movement therewith;
- said elongated rod extending through said hollow output shaft and said elongated opening of said motor;
- a resisting biasing means supporting said motor on said base of said motor sleeve;
- a power supply powering said motor;
- a repelling dish positioned above said motor and having an opening in said dish enabling said elongated rod to pass therethrough;
- said dish having a coupling means coupling said dish to said motor output shaft;
- and
- a switch means for energizing said motor at predetermined times when the weight of an undesirable animal upon said dish overcomes the resistance of said biasing means causing said motor output shaft to move reciprocatively with respect to said rod causing said motor to move reciprocatively with respect to said motor sleeve and said rod and compress said resisting biasing means to thereby rotate said hollow output shaft and said coupled dish.

A rodent repelling bird feeder, comprising:
- an elongated rod having first and second ends, said first end of said rod having a support means thereon, said second end of said rod having a support means for supporting the food container of the bird feeder;
- a motor sleeve having a base and side walls projecting perpendicular from said base, said elongated rod secured to the center of said base of said motor sleeve;
- a motor having first and second ends, a hollow output shaft and housing, said motor having an elongated opening extending from said first end to said second end of said motor;
- said motor being mounted in said motor sleeve for reciprocative movement therewith;
- said elongated rod being positioned through said hollow output shaft and said elongated opening of said motor for reciprocative movement therewith;
- said base of said motor sleeve having a cavity into which a spring is mounted;
- said spring supporting said motor on said base of said motor sleeve;
- said motor and said sleeve having a cover for protecting said motor and sleeve from the weather;
- a power supply powering said motor;
- a repelling dish positioned above said motor;
- said dish having an opening in the center of said dish enabling said elongated rod to pass therethrough;
- said opening being protected from the weather by a guard secured to said rod and extending outwardly and downwardly over said rod opening;
- said dish having a coupling means coupling said dish to said motor output shaft;
- a switch means for energizing said motor at predetermined times when the weight of an undesirable animal upon said dish overcomes the resistance of said biasing means causing said motor output shaft to reciprocate with said rod causing said motor to reciprocate with said motor sleeve and said rod and compress said resisting biasing means to thereby rotate said hollow output shaft and said coupled dish, and
- a control switch connected in-line between the power supply and the switch means.
12 more elements
A bird feeder, comprising:
- a food container for holding bird feed;
- a hanger system operatively connected to the upper end of said food container for suspending the food container from a support;
- said hanger system including a dish positioned above said food container;
- said hanger system including means for rotating said dish when an animal of a predetermined weight moves thereon so that the rotating dish will dislodge the animal from the dish.
