Abstract
A ground inserted rod supports at its upper end a base having a cup-shaped member in which is loosely received a motor housing. During motor operation an eccentric blade imparts random movement to the motor housing to cause same to impact the cup-shaped member to impart vibratory movement to the ground inserted rod for wave generation. A battery holder provides a self-contained power source such as a low voltage dry cell battery.
Claims4
A rodent deterring device for generating constant sonic waves over a period of several hours, said device/comprising,
- a rod for inserted ground engagement,
- a base including a cup-shaped member thereon,
- a motor assembly including a motor housing loosely confined within said cup-shaped member, a motor in circuit with a power source/and having an output shaft, eccentric means on said shaft imparting erratic motion to the motor housing during motor operation, and
- said motor housing forcefully contacting the cup-shaped member during motor operation to impart vibratory motion to the rod for generating sound waves in the ground.
