Abstract: 900,658. Coin-freed vending apparatus ROWE MANUFACTURING CO. Inc. Aug. 28, 1959 [Dec. 24, 1958], No. 29404/59. Class 27. A vending machine has pivoted shelves 24 which are released in succession from bottom to top by a traveller 40 movable upwards by a coil spring 44 in steps controlled by a latch 54 engaging stops formed by openings 36. On insertion of coins, a bar 86 is freed to allow a plunger 82 to be pulled out and move a cam plate 96 to the left. A slot 106 in the cam plate acts on a pin 104 and moves a bar 64 downwardly so that pins 56, 58 in slots 60, 62 cam the bar to the left and cause the surface 66 of a notch in the bar to release the latch 54. The traveller moves up until the latch engages the stop surface 68 on the bar and then, on return of the plunger 82, the bar moves up and to the  right, thus allowing the traveller to move a further distance until the latch engages the next stop opening 36. In the course of this further movement, a cam 72 on the traveller moves a shelf-supporting wire 20 to the left so that a bent portion 22 is out of engagement with a flange 30 and the shelf can swing down. When the last shelf has swung down, the traveller moves up until it meets a projection 116 on the bar 64 and pulls the bar up until the pin 104 is in an enlarged portion 120 of the slot 106 and in the top portion of a slot 118 in a plate 94 rigidly secured to the machine frame, so that the plunger 82 is locked against further operation. To reset the shelves, the traveller is moved manually downwards and a cam 112 rotates them to a horizontal position and a cam 108 shifts them laterally to the right.
