Abstract: 594,148. Testing and sorting coins in coinfreed apparatus. TRIGGS, W. W. (Wurlitzer Co., R.). March 8, 1945, No. 5823. [Class 27] In mechanism for testing coins and sorting them into their several denominations, a preliminary test, applied after insertion through a common inlet, sorts the coins on to either of two superposed runways which convey them to different zones of a further testing device comprising spaced deflectors arranged to pass coins leaving the runways with correct trajectories to accept outlets. The mechanism shown is mounted on a base-plate 10, Fig. 3, the front upper half of which is covered by a gate plate 12, Figs. 1 and 4, and the lower half by a reject receptacle 16, Fig. 1. The gate plate and rear wall of the reject receptacle are spaced from the base plate to provide a passageway from a common entrance 32 for three coins A, B and C to accept outlets 20 and 21, defined by pins 52a, for the coins A and B, and a common reject outlet 22. An accept chute 17 for coins C is mounted on the rear of the base plate. Coin C is the largest and heaviest, and coin B the smallest and lightest. A coin C on entering at 32 is checked by the spaced fingers 37 of a counterweighted balance lever 36, which rocks and discharges it on to a runway 33, whence it passes between a magnet 38 and its keeper 39 and between deflector fingers 40 and 41 to an entrance aperture 18 leading into the accept chute 17. If incorrect in metallic content or weight, yet passed by balance 36, its trajectory does not lie between the deflectors 40 and 41, and it falls to the reject outlet 22, or may be diverted to the reject receptacle 16 and thence to an outlet 26 adjacent 22. Coins A and B pass through the fingers 37 to a lower runway 34 and thence past a second magnet 39. The trajectory of a coin A, if sound, is between deflectors 41, 42 and 44 on to an anvil 47 whence it rebounds beneath a pin 52 to the accept outlet 20. If spurious, it is checked by one of the deflectors, or pin 52, and falls to the reject outlet 22 or is diverted to receptacle 16. The path of the smallest coin B from the runway 34 is between deflectors 42 and 44, and between spaced fingers 51 of a pivoted cradle 48 to the accept outlet 21. The cradle is provided to arrest other coins and slugs of larger size which may reach it, and pivots to discharge them to outlet 22. To intercept light discs, a finger 55 of a counterweighted lever is located in the path of coins A and B as they fall on to runway 34. This finger also arrests underweight coins B, and is not displaced sufficiently to pass underweight coins A owing to a second lever 53a coming into action to increase its bias with the larger displacement. Washers are impaled by a pivoted hook 58 which also thrusts under-diameter coins through a gauge aperture 59 whence they fall to receptacle 16. Clearing apparatus.-The mechanism is cleared by depressing a lever 75, which, through a roller and cam, swings the gate 12 on its pintle 62. A knock-out plate 13 to the rear of the base plate follows its movement, and has a series of forwardly facing coin ejecting lugs which enter apertures in the base plate at points where coins may be arrested. Discs held by the magnets are swept clear by a pivoted arm 72 also actuated by the lever 75.
