ABSTRACT:
This invention provides a simple and inexpensive vibrator. Upper and lower linked arms are used to hold equal weights attached at the ends of the arms. The arms are attached to collars which spin. A bent axle is used to cause displacement of the upper collar with a resultant shortening of the effective radius of rotation of one of the weights at a determined position in the circle of rotation. This shortening of the effective radius of rotation imparts a vibratory motion to the vibrator.
