A variable vibrator mechanism ( 10 ) for feeder machines. The vibrator mechanism ( 10 ) includes a first member ( 12 ) and a second member ( 14 ) arranged telescopically with one another. The first member ( 12 ) and second member ( 14 ) have eccentric weights (axially offset) ( 16, 26 ), and are adapted such that the rotational displacement between the eccentric weights ( 16, 26 ) is varied by varying the longitudinal displacement between the first and second member ( 12, 14 ). Thus allowing the vibrational characteristics of the vibrator to be adjusted by simply varying the displacement between the first and second members ( 12, 14 ). |
