ABSTRACT:
A vibratory device which provides vibratory motions for screens, shakers, and vehicles which utilize such motions is described. Rotatory motion is imparted to a rotating frame which transmits to motion to an unbalanced weight assembly. Rotation of the unbalanced weight assembly generates vibratory forces in defined directions. The rotating frame imparts a gyroscopic effect which stabilizes the vibratory device in all directions other than those in which vibration is desired.
