Vending machine selection and control
Abstract
Abstract A SELECTION AND CONTROL MECHANISM FOR A VENDING MACHINE IN WHICH A PRIMARY LIQUID IS DISPENSED AS WELL AS VARIOUS ADDITIVES SELECTED BY THE CUSTOMER. THE MECHANISM INCLUDES A PRIMARY SELECTOR WHICH IS NORMALLY BLOCKED FROM SHIFTING BY A RELEASE DEVICE CONTROLLED BY A LATCHING DEVICE. WHEN THE LATCHING DEVICE MOVES TO ITS LATCHING POSITION, IT ALSO MOVES THE RELEASE DEVICE SUCH THAT THE SELECTOR CAN BE DEPRESSED, AND IT FURTHER HOLDS THE SELECTOR IN ITS DEPRESSED POSITION. AS THE SELECTOR MOVES TO ITS DEPRESSED POSITION, IT ACTUATES A PRIMARY SWITCH. SECONDARY SELECTORS ARE ALSO PROVIDED AND THEY OPERATE SECONDARY SWITCHES WHEN DEPRESSED. THE LATCHING MEANS ALSO HOLDS THE SECONDARY SELECTORS IN THEIR DEPRESSED POSITIONS. THE PRIMARY SELECTOR CAN BE DEPRESSED INDEPENDENTLY OF THE SECONDARY SELECTORS. EACH SECONDARY ALONG WITH IT AND MAY, LIKEWISE, CARRY ANOTHER SECONDARY SELECTOR ALONG WITH IT.
