Charles August Fey, a Bavaria-born inventor, was living in San Francisco when he invented his first gambling machine in 1984. His games grew to be so popular at local bars, he quit his day job and opened a factory to start mass producing them, most notably the Liberty Bell machines in 1899. A lot of the functionality from that early game remained in place through much of the 20th century. Watch this video to see the seven mechanical actions set into motion when you pull back the bandit’s arm. The inner workings are probably a little more complex than you expect.
Given that a lot of old slot machines are hand built, it isn’t surprising that coins can get jammed on their way through the mechanism. Big warning: If your machine jams, don’t force the arm or you can break, twist or damage a part inside. Different models and makes tend to have common jam points. The Mills model shown in the above video can have coins stuck in the “elevator” section that displays the last five coins dropped into the machine. Getting the slot working again can be as simple as cleaning the gunk off of an old part. You just need to be smart when you’re disassembling and reassembling the machinery.
Okay, there are plenty of more places where a coin can get stuck and the above video demonstrates how to fix a variety of jams. It also explains how to disassemble the major parts of the machine and where common problem areas are.
