If the small spring attached to the safety slide lever breaks or loses tension, or if the lever gets generally gummed up, the safety slide can travel backwards on every pull of the handle, preventing the machine from paying off. Although these are relatively minor parts, they sometimes cause problems. The entire safety slide/lever mechanism is sometimes called the “non-beating” mechanism for obvious reasons. If the machine has been jarred during its cycle, however, the lever trips and the slide moves backwards to prevent coins from passing through. It its normal position, it allows coins to pass down through it and out of the mechanism into the payout chute. When we remove the payout slides you will be able to see the safety slide itself, which is really nothing more than a thin piece of metal with a hole in it. The safety slide lever assembly is the closest thing an antique slot machine has to a pinball machine’s “tilt” mechanism.
It’s secured by a shoulder screw visible in the photo above, plus a spring that is attached to the underside of the base plate. I chose to remove it now, so that’s what the photos reflect. The part in the photo above can be removed at this point, although it is probably easier to wait until the coin slides are removed.
