  • Vibratory device with controlled actuation
    Patent number: 4196637
    Abstract: A vibratory device has a vibrating chassis disposed horizontally or inclined and which is actuated by linear vibration by means of a vibrator having two unbalanced shafts rotating synchronously in opposite directions. For obtaining continuous regulation, during functional operation, of the reciprocal angular phase displacement of the unbalancing masses, the unbalanced shafts are connected with two drive shafts coupled by a chain. The two runs of the chain can be altered in length by adjustment of a pivoting lever.
