  • Patent number: 4399903
    Abstract: To greatly increase the coin holding capacity of the cash box of one well known product dispenser and to simplify and render more convenient the placement of the cash box in the dispenser, the cash box is restructured to utilize all available space in the dispenser without interfering with or changing in the slightest the operation of the coin mechanism and the associated product dispensing components. In lieu of a lock, the cash box is held securely in its working position by simple spring pressure. The improved cash box is equally adaptable to double or single column product dispensers.

  • Patent number: 4363393
    Abstract: The coin receiving capacity of a coin controlled mechanism is increased to compensate for increased cost of merchandise dispensed from a known type of vending machine whose coin holding capacity has been increased for the same reason. The mechansim has also been rendered more convenient and more reliable in operation and the number of parts in the mechanism has been significantly reduced without loss of essential function. Continuous turning of the dispensing knob in one direction has been made possible in lieu of forward and reverse turning required with the unimproved mechanism. The improved mechanism is fully compatible with existing vending machines in the field.
