Abstract: A coin acceptor which receives coins in a slanted coin chute with a final size gauge system. The coin is first rebounded against a tapered wall and enters a first zone. All three coin sizes enter the first zone and then the lightest weight one passes down a tapered ramp which is spring loaded, but the lightest weight coins will not depress the ramp and therefore such coins are diverted into a second zone. The heavier different sized coins pass down and trip the tapered ramps, both a first and second one, and then the widest of the coins continues downwardly in the first zone to be processed and sized for diameter. The largest diameter coin is trapped between two pins where it is then tilted off of a ramp onto a diverter and passes into a third zone for processing. As all of the coins reach the bottom of their three separate zones, they enter into a final size gauge system which has three coin chutes sized precisely to reject any coin which is bent, burred, or oversized.

Abstract: This invention relates to testing a coin by catching the coin, while it is moving, between a varying radius cam and a pin on a low inertia carrier. The carrier axle is in a fixed relationship to the cam. The coin's momentum plus weight turn the carrier until an end travel point is reached and momentum causes the coin to depart the carrier and go into an accept outlet. Additionally, magnetic fields passing through the coin's path provide further forces on the coin which help pull magnetic coins off the carrier into the reject outlet prior to the end travel point being reached. Undersize or underweight coins leave the carrier early and divert to reject. Oversize coins complete full travel, but cannot pass through to the accept outlet, and move back to reject outlet. Also, stringing of acceptable coins for retrieval is defeated by a trip in the accept outlet. Blockage of the reject outlet is defeated by a lever to stop rotation of the carrier in conjunction with a pin on the carrier to block spillover coins.
