Abstract: 749,612. Testing and sorting coins in coinfreed apparatus. NATIONAL REJECTORS, Inc. Oct. 28, 1953 [July 27, 1953], No. 29783/53. Class 27 A coin separator has a hinged clearing wall 30 fitted with a gauge element 132 cooperating with another gauge element 128 on a stationary frame 20 and the element 132 is loosely pivoted at 134 and carries a conical-ended pin 136 so that, when the clearing wall is adjacent the frame, the pin enters a hole 130 in the frame and places the element 132 in precisely spaced relation to the element 128, irrespective of manufacturing tolerances or wear in the clearing wall hinge. Coins are inserted between guides 19, 21 and 31 and are first tested between spaced fingers of a counterweighted cradle 56 that intercepts larger coins 190 and, if they are of the correct size and weight, tilts to direct them to a runaway 50 on the clearing wall 30. The runaway 50 conducts the coins 190 through the field of a magnet 36 on another hinged wall 38 and, according to their electrical conductivity, they are retarded so that they fall into either an accepted or rejected coin shoot. Unduly thick coins will fail to pass through the space between the wall 38 and the frame 20, this space being determined by a fixed spacer 42 and adjustable spacer screw 46 and the arm 38 being biased inwards by the attraction of the magnet 36 and of another magnet 40. Smaller coins will pass between the fingers of the cradle 56 and a second type of coin 192 will be large and heavy enough to strike a lever 70 pivoted at 66 and move it so that a vertically pivoted wire 72 is momentarily withdrawn from the coin passageway and then returned by another lever 68 also pivoted at 66 to test the coin for a hole or surface defect. The coin 192 then rolls down a runway 52 and is tested for electrical conductivity by the magnet 40. Smaller coins than the coins 192 are deflected by the lever 70 into register with an opening 126 in the frame, the coins resting on the gauge element 132, which may have a hardened face. The smallest coins 194 are deflected through the opening 126 by a counterweighted deflector 84 and a fixed deflector 188 into a subframe 124 where they are tested by devices, not shown, for weight, diameter, thickness and electrical conductivity. Coins 196, slightly larger than the coins 194, will be gauged between the element 132 and the arcuate element 128 fitted over the opening and, if not oversize, will be deflected downwards by a pivoted deflector 176 until they strike spaced fingers on a cradle 162 pivoted on a support 154 hinged to a subframe 138. Too thick coins will, however, be held between the subframe 138 and a hinged wall 146. Coins 196 of correct weight and large enough to be held by the fingers of the cradle 162 will rotate the cradle so that the coins are directed to an' accepted coin shoot 174, unless the coins are magnetic, in which case, they will be held by a magnet 170 fitted on the support 154 above the cradle pivot. As the coins have been virtually brought to a stop and as they are partially supported by the cradle, the size and power of the magnet need not be great. Oversize coins on the cradle 162 will be halted against a pin 163 and underweight coins will fail to rotate the cradle. Clearing apparatus. - Depression of a pivoted plate 114 rotates a wiper blade 120 between the frame 20 and movable wall 38 to clear out coins held by the magnets 36 and 40 and, at the same time, a cam surface 122 engages a roller 112 on the clearing wall 30 so that it is moved outwards against the action of a spring 32. As the clearing wall 30 moves away, a hinged stripping plate 100 is disengaged from a spacer 98 so that projections 104 and 106 move through openings 108 and 110 on the wall 30 and clear coins held adjacent these openings. Movement of the wall 30 also removes an adjustable spacer 90 from contact with the support 154 below a pivot 144 and, under the action of gravity and of a spring 158, the support and the wall 146 move away from the subframe 138, the movement of the wall being limited by a tap 150 in an aperture 152 but the support moving further until its upper end hits the upper end of the wall. The cradle 162 is thus withdrawn from the coin passageway and an air gap is produced between the magnet 170 and the passageway so that any coins held in the passageway are released. The deflector plate 176 is also allowed to rotate by the withdrawal of the clearing wall 30 and any coins held at the gauge element 128 are released. Baffles 92, 94, 96 prevent coins from slipping between the walls 30 and 38 when the wall 30 is moved away. Specification 749,619 is referred to.
