Abstract
A finishing machine comprising a generally annular finishing chamber having a bottom and upstanding side walls, centrally located vibratory means comprising a substantially vertical shaft with major and minor eccentric weights at each end thereof, one of the eccentric weights at each end of the shaft being fixed, the other of the eccentric weights at each end of the shaft being moveable with respect to said shaft, means operatively associated with said moveable eccentric weights for effecting movement thereof within permissible limits, and limit means defining the permissible movement of the moveable eccentric weight at each end of the shaft, for respectively (a) increasing or decreasing the intensity of vibrations, or (b) reversing the direction of the force factor and hence the direction of flow of mass within the finishing chamber concurrently with an increase or decrease in the intensity of vibrations, depending upon whether the moveable eccentric weights are (a) two minor eccentric weights or two major eccentric weights, or (b) one major eccentric weight and one minor eccentric weight; a vibrogyratory energizing unit, especially suitable for use in such a finishing machine; and a novel method of finishing in such machine, are all disclosed.
