Disc size classifier and method

摘要

A coin classification apparatus and method which is adaptable to a purse, wallet or as a separate coin purse. The apparatus comprises a plurality of stacked troughs, equalling the number of coin sizes to be classified. Each trough is equipped with a plurality of restriction apertures which restrict the passage of coins larger than the aperture but allow the passage of all other coins, the apertures on a given trough are the same size. The top trough has the largest apertures while the bottom trough has no apertures. Loose coins are deposited in the top trough and coins are classified in separate troughs as smaller coins pass successively through apertures.
