Separately Acting Series Controllers Patents (Class 221/298)
  • Patent number: 3934692
    Abstract: Disclosed is a coin and currency changer utilizing a coin chute having two continuously intersecting arms wherein coins may be alternately stored. A plunger assembly is positioned at the bottom of the chute along the line of intersection of the two arms and is operative to dispense one coin at a time therefrom. The coin in the chute immediately above the dispensed coin is retained within the chute by a pinching action between the plunger assembly and the structure of the chute. A sensor is positioned in operative relation with the plunger assembly and senses the actual dispersal of the coins from the chute. Control circuitry counts the number of coins dispensed and is operative to inhibit functioning of the system if more than the desired number of coins is actually dispensed. There is further provided means for maintaining a proper number of coins within the chute by transferring the coins from a bulk hopper to the chute.
