Mills Roulette


    Catalog photo of the Mills Roulette.


    This machine was changing hands. I was hired to put it in good working order to make it reliable but I had just a few days to do so. I had never seen the workings of a Mills Roulette so I couldn't pass up the chance.


    Built on the order of an upright slot from the same era.


    At the beginning of play, the color wheel spins ejecting the ball around the dish. The steel ball falls into a depression on the end of a color segment and revolves until the ball contacts the pawl on the projecting arm and the payout is triggered.


    You can see a very old repair in the form of brazed welds. In the forefront is the governor for the speed of the wheel. The black iron casting had pin striping under a layer of grime.


    The right side of this photo shows a governor. Just below the governor is a spring barrel. When the crank on the side of the cabinet is turned, it winds the spring. It is similar to a spring in a phonograph. The spring spins the center wheel.


    Side view of the coin head, extreme right of photo. Arms connected to the coin head sense the presence of a coin to determine payout.

    Vertical rods connected to the fingers fall into a hole in a rotating plate. These rods determine if the roulette ball has stopped on a color slot where a coin has been wagered.
    This plate is pictured clearly in the photo describing the governor.
