Claim:
1. A tamper drive apparatus comprising: a wobble shaft rotatable about a central horizontal axis and disposed within a first bearing, the wobble shaft including an eccentric portion of the wobble shaft fixedly coupled to an eccentric hub recess; the eccentric hub recess being disposed within a movable bearing, wherein the axial rotation of the wobble shaft causes the eccentric hub recess to rotate within the movable bearing to induce rotation movement of the movable bearing; a yoke coupled to the movable bearing such that rotation movement of the movable bearing causes the yoke to reciprocate horizontally; and a drive shaft fixedly coupled to the yoke; wherein the reciprocal horizontal movement of the yoke and the drive shaft results in vibration of the yoke.
