- The patent describes an anti-stringing device for a coin acceptor to prevent fraud using coins attached to strings.
- The device includes a main plate and a side plate defining a coin path with a slot narrower than the thinnest coin to catch strings.
- Barbs inside the slot retain the string to prevent retrieval of the coin, ensuring the coin cannot be manipulated back through the coin path.
- An acceptance channel and a rejection channel sort genuine and counterfeit coins, with sensors to detect and prevent fraudulent activities.
- Additional slots and mechanisms are described to further prevent string manipulation, including a second slot in a wall between channels.
- The design aims to be reliable, durable, compact, and inexpensive to manufacture while effectively inhibiting cheating attempts.
