Claims
- 1. An apparatus for sorting coins of different denominations, said apparatus comprising:
- a rotatable member having a resilient surface;
- a stationary member having a surface that is substantially parallel to said resilient surface and positioned sufficiently close to said resilient surface so that at least portions of the stationary surface press any coins in contact therewith into the opposed resilient rotatable surface so that the resiliency of the rotatable surface urges the coins against the stationary surface with sufficient pressure to prevent radial movement of the coins by centrifugal force due to rotation of the rotatable member, while permitting circumferential movement of the coins by rotation of the rotatable member; and
- selected areas of the surface of said stationary member being recessed for releasing any coins entering such recessed areas from the pressure of said resilient surface and thereby permitting radial movement of coins within the recessed areas by centrifugal force due to rotation of the rotatable member, said recessed areas being shaped to (1) guide coins in single file along a predetermined path, and (2) permit coins of different sizes to escape radially from between said surfaces, by centrifugal force, at different preselected positions along the periphery of said stationary member.
- 2. A coin sorting apparatus comprising:
- a pair of substantially parallel horizontal plates forming a pair of opposed surfaces which have at least portions thereof spaced slightly away from each other to permit coins to slide between the opposed surfaces;
- one of said plates being stationary and the other plate being mounted for rotation about an axis that is substantially perpendicular to said opposed surfaces;
- the rotatable plate having a resilient biasing surface for urging coins pressed therein toward the opposed surface of the stationary plate; and
- the stationary plate having a plurality of recessed areas therein for releasing any coins entering such recessed areas from the biasing pressure of said resilient surface and thereby permitting radial movement of coins between the two plates by rotation of the rotatable plate, said recessed areas being shaped to (1) guide coins in single file along an arcuate path between the plates, and (2) permit coins of different sizes to escape radially from between said plates at different predetermined positions around the periphery of the stationary plate.
- 3. A coin sorting apparatus as set forth in claim 2 which includes means for feeding coins between said rotatable and stationary members for sorting, said feeding means leading coins into one of said recessed areas in said stationary surface.
- 4. A coin sorting apparatus as set forth in claim 2 wherein said stationary surface includes a raised or non-recessed area between the recessed area that guides the coins in single file along said predetermined path and the recessed area that permits the smallest coins to escape radially from between said surfaces, said raised or non-recessed area pressing coins larger than said smallest coins into said resilient surface to prevent the escape of said larger coins at the predetermined position where the smallest coins are permitted to escape.
- 5. A coin sorting apparatus as set forth in claim 2 wherein said stationary surface includes a raised or non-recessed area between each pair of recessed areas that permit coins of different sizes to escape from between said surfaces, each such raises or non-recessed area pressing coins larger than the coins that are permitted to escape at each predetermined position into said resilient surface to prevent the escape of such larger coins until they reach another recessed area.
