An apparatus for providing gyratory motion to a paint can for mixing the contents of the paint can. The paint can is clamped between an upper and lower clamping plate of a clamping mechanism, which clamping mechanism is fixed to a rotatable disc rotatable in a vertical plane. The lower clamping plate is rotatable independently of the rotation of the mounting disc. The upper and lower clamping plates are moveable toward and away from each other simultaneously via a pair of threaded rods. The lower clamping plate is also provided with a plurality of angularly spaced-apart vertically pivotal, clamping fingers, the upper portions of which extend through slots formed in the circumference of the lower clamping plate, which fingers help to clamp and automatically center the lower rim of a paint can being clamped and mixed. The fingers are urged upwardly before the upward sliding movement of the lower clamping plate via a strike plate slidingly mounted with respect to the drive shaft of the lower clamping plate. A pair of independent and separate drive assemblies are used, one for driving the mounting disc, and one for rotating the lower clamping plate. A pair of ramps are also provided, which pair of ramp plates allow for the continuous in-feed and out-feed of paint cans to be mixed.
