    Hi,

    I'm trying to repair a Coin Acceptors, Inc. coin acceptor. It's for a Williams Lucky Strike, but was used in other machines of that era. It accepts .05, .10 and .25 coins through a single coin chute.

    Here's a couple of pics.

    NOTE: I found some of the missing pieces and figured out where that counter weight goes. Now it accepts nickels and the diverter is working (it wasn't earlier). However, it rejects quarters about 90% of the time. AND.... what is that cast part that's attached to the bottom right side of the separator cover plate? It certainly doesn't belong there.

    TIA

    Does it reject quarters when coinmech is build in the coindoor?
    Coinmechs tend to give problems due to the angle of the pinball machine. They kinda lay against the door.
    I also had this problem and added some bushings on the topside of the coinmech the straighten them up. Works fine now.

    About that cast part, i also don't see any use for it. Maybe, if you know the manufacturer, there could be some manual of this mech.

    That's a washer catcher. That particular one looks like it goes above the quarters cradle, but you are missing the small flat piece of sheet metal that holds it in place. I've annotated your picture and show where they go. Normally, as shipped from the CoinCo factory, there would have been TWO washer catchers: one for the quarters cradle and one for the nickels cradle. The nickels cradle still has the metal cover and screw which would have held the nickel washer catcher in place.

    It is not necessary to have the washer catchers installed. All they were for is to catch flat washers of the same size as a coin. Kids would never try that trick would they?

    Show me a picture of the backside of that coin acceptor. There should be some adjustments there to make to improve coin acceptance of quarters.

    Note: this type of coin acceptor was used on cigarette machines, soda pop machines, and jukeboxes back in the 60's and 70's. I repaired many of them.

    At the very back of the Williams 1966 Parts Catalog is the service manual for the CoinCo 70 series N-D-Q (and penny) coin acceptors (show adjustments too):

    Great,

    Thanks for all of the help and useful information. I think the quarters problem is that the magnet has lost strength. Luckily as Ken mentioned, these were used in various vending devices. I happened to have the upper parts from an old Vendo Pepsi machine. I swapped it for the one from my Lucky Strike, made a few mods and all is good now. The next thing to do is fabricate the coin switch spring levers that the coins hit to add credits. Someone removed two of them.
    You can see the one I’ve made from a guitar string.

    Be careful. Sometimes between vending machine applications and jukebox/amusement applications, CoinCo changed the location of the slots the coins come out of at the bottom of the coin acceptor. Typically, they swapped where the quarters and dimes come out.

    Thanks Ken,

    I kept the original frame and everything from the separator down. I changed the guts, all of the components that are on the spring loaded axel. It was the the same set up, except for an additional cam. Boy it was tough swapping that out, lots of tension on that spring.

    What drove me nuts for a while was I had three mechs and I was trying to make one good one. But even though the parts looked interchangeable, they were just slightly off. That was until I realized that 2 of the three were National Acceptors and the one I needed was a Coin Acceptor Inc model. At first the nickels weren't dropping correctly, I fixed that. That's when the quarters stopped dropping correctly.

    Then I realized that had had the guts from my old Vendo lying around. Luckily the swap worked.

    I just made new springs from a 17 gauge guitar string. Now the game operates as it did when new, although I did bend the credit reel switch so even though it will coin up, it's still set on free play. Now to fill the hole someone drilled in the coin door when they installed a momentary switch to add credits .
