Definitions

  • Some coins have substantially the same diameter, substantially the same electrical conductivity, and substantially the same resilience; and such coins may differ only in the respect that some of them have rims whereas others of them do not. To separate those coins automatically, it would be necessary to provide a coin separator that could separate rimmed coins from coins that do not have rims.
  • the present invention provides such a coin separator, and that coin separator has relatively movable rim-engaging members. It is therefore an object of the present invention to provide a coin separator that has relatively movable rim-engaging members.
  • the surfaces of the relatively movable rim-engaging members of the coin separator of the present invention are conical. As a result, those surfaces can always coact with the sides of tested coins to subtend the same angle. That angle must be small enough to enable the masses of the tested coins to force those rim-engaging members to move apart, but that angle must be large enough to enable the apexes of those surfaces to engage those portions of the surfaces of the coins which abut the inner faces of the rims of those coins. The angle which meets these requirements is an angle of approximately forty-five degrees.
  • the present invention equips the relatively movable rim-engaging members of a coin separator with conical surfaces having apex angles of approximately ninety degrees.
  • the period of time within which the relatively movable rim-engaging members of a coin separator must engage and attempt to hold the rim of a coin is necessarily limited; and if a coin to be tested is moving at an unduly high rate of speed, the period of time within which the relatively movable rim-engaging members of the coin separator are permitted to engage the rim of that coin may be insufficient to enable those rim-engaging members to hold that rim.
  • the present invention makes cer- 3,l7e,3t8 Patented Apr.
  • the relatively movable rim-engaging members of the coin separator have sufficient time to engage and hold the rim of a coin; and it does so by intercepting all coins introduced into it and by forcing those coins to change direction before they can engage those rim-engaging members.
  • the present invention makes certain that the relatively movable rim-engaging members of the coin separator have sufiicient time to engage and hold the rim of a coin even if the coin separator is spaced far enough below the level of the coin slot in a vending machine to enable the coins to be tested to develop a high speed before they reach that coin separator. It is therefore an object of the present invention to provide a coin separator that intercepts all coins introduced into it and that forces those coins to change direction before they can engage the rim-engaging members of that coin separator.

One end of that spring bears against the horizontally-directed arm of the scavenging lever 36, and the other end of that spring bears against the rearwardlyextending portion of the pin 46.

  • the conical face of the plunger 190 extends an appreciable distance beyond the inner end of the housing 94. As a result it will be the plunger 100, and not the housing 94, that will receive coins to be tested. It will also be noted from FIG. 5 that the conical face of the plunger 1% does not play any part in the securing of that plunger within the housing 94 and does not, in the absence of a coin, limit the extent to which that plunger can move relative to that housing. In addition it will be noted from FIG. 5 that the apex angle of the plunger 101 is approximately ninety degrees.
  • the numeral 106 denotes a gate for the coin separator of FIGS. 16; and that gas has a plate 108 secured to the rear face thereof by fasteners 110, such as screws.

  • a coin separator that has a wall, a second wall that is spaced from the first said wall to define a coin passageway, a housing that is held adjacent one of said walls and that holds a rim-engaging element for movement relative to said one wall, said rim-engaging element having a conical face that is adapted to project outwardly from said housing and to extend into said coin passageway, a resilient element that normally holds said conical face of said rim-engaging element within said coin passageway but that can yield to permit. movement of said conical face out of said passageway, and a guide that is spaced from the apex of said conical face a distance slightly less than the longest distance between the inner edge and the outer edge of the rim of a coin inserted in.
  • said coin separator to force authentic coins to move said rim-engaging element, said coin passageway being substantially clear adjacent to but forwardly of said rim-engaging element, said conical face of said rim-engaging element projecting far enough from said housing to enable said housing to be disposed wholly out of the paths of coins moving through said passageway.
  • a coin separator that has a coin passageway and a housing that holds a rim-engaging element for movement relative to said coin passageway, said rim-engaging element having a conical face that is adapted to extend into said coin passageway, said conical face normally lying in the path of authentic coins in said passageway and responding to the movement of an authentic coin in said passageway to move away from said authentic coin and thereby permit said authentic coin to move into register with the apex of said conical face, said apex of said conical face thereafter intercepting a further portion of the rim of said authentic coin and causing said authentic.
  • said coin passageway being substantially clear adjacent to said rim-engaging element so coins can approach and leave said rim-engaging element at determinable speeds.
  • a coin separator that has a wall, a second wall that is spaced-from the first said wall to define a coin passageway, a housing that is secured to one of said walls and that holds a rim-engaging element for movement relative to said coin passageway, said rim-engaging element having a face that normally extends into said coin passageway to receive and to be moved laterally of said coin passageway by an authentic coin, and a member that receives inserted coins and causes said coins to change.
  • said member tending to provide a uniform speed for said coins as they approach said rim-engaging element, said rim-engaging element havinga face thereon which can coact with inserted coins to subtend the same angle irrespective of any movement of'said'rimengaging element laterally of said coin passageway, said rim-engaging element tending to force rimmed coins to change direction while permitting said coins to move substantially continuously through said passageway.
