ABSTRACT:
A buffer/cleaner for objects such as jewelry or coins includes a bowl for holding the objects. The bowl also holds a treatment material consisting preferably of a carrier material. The carrier material may be granular, a powder, fibers, etc., and may be pre- or post-treated with a chemical buffing or cleaning agent or abrasive. The bowl is mounted resiliently on a vibrating arm, preferably by using a resilient glue or a resilient insert in a channel separating an upper end of the vibrating arm from a protruding coupling portion on the bowl, into which coupling portion the arm extends. The arm is caused to vibrate by a driver motor, preferably of a pulsed electromagnetic type. When the arm vibrates, the bowl is "whipped," that is, the bowl is both translated and rotated about a resilient pivot point out of phase with the vibrating arm, but at substantially the same frequency. This whipping motion induces a counter-flow of the treatment material in separate regions of the bowl. The particles of the treatment material thus contact the objects to be buffed or cleaned evenly over the surface of the objects as they move along in the counter-flows.
