  • Coin escalator for gaming devices
    Patent number: 5558197
    Abstract: The improved coin escalator of the invention includes a smoothly curved coin transport channel positioned on the outside circumference of an arcuate back plate. The channel is defined by spacer plates which are attached to the outer curved surface of the back plate and edge plates integral with the spacer plates. Downtime of the gaming device is minimized because the smoothly curved shape of the transport channel prevents coins from becoming jammed therein.
