Abstract:

A precious metal filings collection box for use by jewelers or other tradesmen is disclosed which provides a pilfer-proof system for collection of precious metal filings which fall from jewelry or other articles as they are worked. The collection box is shown as being part of a jeweler's bench pan and is formed of a box-like unit having a screen mesh top through which the filings fall, but the openings of the screen are too small to permit the jeweler's hand or finger to pass therethrough. A locked bottom drawer which collects the filings is provided to prevent unauthorized removal of the precious metal filings.
