Abstract (en)
[origin: US4440034A] An eccentric vibrating machine which includes parallel shafts each carrying an eccentric mass. A gear rotatably journalled on a first of the shafts is drivingly connected to the second shaft for mutual rotation of the gear and second shaft. A shifting coupling is mounted on the first shaft and is selectively engageable with the gear at multiple angular positions around the gear to couple the first shaft to the gear and thereby selectively vary the phase angle relationship of the eccentric masses carried on the two shafts. A manual shifting control device is carried on the first shaft, and can be manually actuated to selectively engage the shifting coupling with the gear.
