Definitions

  • the invention relates to devices for choosing, between coins or tokens able to roll, those which have a prescribed characteristic, which find application in automatic telephone boxes and in automatic machines for the sale of articles.
  • German patent No. 602,908 describes an apparatus for this purpose comprising two magnets M and E which are not integral and one of which, M, is fixed, of the type according to which a part has the choice between two paths. If it is not magnetic, it is not attracted by magnet M and it falls through a window A. If it is magnetic in a correct way, it is attracted by magnet M and it continues on its way . If it is too magnetic, when it continues on, it attracts magnet E. But a very magnetic piece can, if it passes quickly enough, not be retained by magnet E. A non-magnetic piece can, if it is launched with skill, arriving at the window opposite the fixed magnet M and playing the role of a correct magnetic piece.
  • the invention overcomes these drawbacks with a device of very high safety which, in particular bind, prevents any part too magnetic to play the role of a correct part.
  • the invention therefore relates to an apparatus for rejecting between coins or tokens those whose magnetic characteristic exceeds a prescribed threshold, comprising a path for coins having an opening in which engages a first magnet when a magnetic coin passes in the path opposite the opening and, upstream of the first magnet, a second magnet, characterized in that the second magnet is integral with the first and is shaped or positioned so that the magnetic force with which it is attracted by a magnetic piece passing in front of him on the way is less than that with which the first magnet is attracted by this same piece when it passes in front of the opening
  • the magnetic force applied to the magnet forming the device is greater than that applied to the magnet forming the obstacle upstream, because the first magnet has more extent than the second and / or because the pole of the first magnet, the closest to the raceway, is closer to the raceway than the corresponding pole of the second magnet.
  • the apparatus of Figures 1 to 3 consists of two vertical flanges l j 2, parallel, spaced from each other by a distance just greater than the thickness of the parts having the prescribed characteristic.
  • the lower edges of the flanges 1 and 2 are inclined downwards from the right to the left in FIG. 1 and are connected by a bottom, so as to define a raceway 3 for the P coins.
  • a yoke 4 On the outer face of the flange 1 is fixed a yoke 4, the axis 5 of which is parallel to the flange 1 and is perpendicular to the direction followed by the parts P along the raceway 3.
  • Two jaws 6 are integral with the axis 5 and enclose a permanent, cylindrical magnet 7.
  • the axis 8 of the magnet 7 is coincident with an opening 9 formed in the flange 1, upstream of the yoke 4.
  • Axis 5 is integral with a worm latch 10 rusting whose beak 11, bent and pointed, faces an opening 12, formed in the flange 1, downstream of the yoke 4.
  • each jaw 6 is welded a branch 14 of a clamp enclosing a magnet 15, of smaller dimension than the magnet 7 and of axis parallel to that of the latter, which can come in the raceway 3 passing through a opening 16 made in the flange 1 upstream of the opening 9.
