Abstract: 906,375. Coin-freed apparatus. ICE-MATIC Ltd. Oct. 17, 1960 [Aug. 16, 1960], No. 28372/60. Class 27. A protective control for a refrigerated automatic vending machine having a refrigerating unit controlled by a thermostatic switch and a refrigerated magazine compartment wherein goods, such as frozen foods, for sale, are stored, comprises an additional thermostatic hightemperature switch 19 controlled by the temperature in the magazine compartment and opening when the temperature rises above a predetermined level to break the holding circuit of a relay 12 which opens a contact 15 in the supply to the control circuit 23 of the vending apparatus of the machine. The relay has a holding contact 13 in series with the switch 19, a contact 14 controlling an indicator lamp 17, and the contact 15 controlling the circuit of the vending apparatus. In operation, the refrigerating unit is switched on and upon the temperature in the magazine compartment dropping to the predetermined level, the switch 19 closes but the vending apparatus will not operate until a push-button 24 is pressed to close the circuit between power lines 16, 21 through the relay which then closes the contacts 13, 14, 15 to hold the relay closed, light the lamp 17 and supply power to the control circuit 23. If the temperature in the compartment falls below the predetermined value, the switch 19 opens to break the holding circuit and open the contacts so that the circuits to the lamp and apparatus are broken. Even though thereafter the refrigerating unit reduces the temperature to close the switch 19, the circuit to the lamp and vending apparatus remain broken so that the machine is incapable of accepting coins and vending articles until the push-button 24 is again depressed. Specifications 687,359, 707,432 and 906,373 are referred to.
