"DRIVE DEVICE WITHOUT TRANSMISSION FOR PRODUCING AN ELLIPTICAL SHAKING MOVEMENT" ABSTRACT OF THE DISCLOSURE A drive device for oscillating a spring-suspended device, such as a sieve or transport device, into an elliptical translational movement with a minimum of rotation. Two unequal and excentrically arranged oscillation masses, rotatably fixed to the device, are rotationally driven each by a motor independ- ent of the other. If the axes of rotation for the two masses are arranged in a certain geometry relative to the center of mass, the device will oscillate with a substantially pure translational, elliptical movement free of tipping movement.
