A mechanical vending machine including: a coinage totalizer, comprising a rotatable counting wheel having a notch therein, which notch moves opposite a latch release post upon required coinage being deposited in the vending machine. A coin lockout slide, which is released by movement of the latch release post into the counting wheel notch, has a cam follower connected to it. The cam follower rides along a cam comprised of a slot which is oblique and transverse to both the slide and a vending machine lockout release means post. The cam is secured to the lockout release means post. That post has pivotally secured to it guide means having slots therein for receiving and directing the movement of merchandise release lever guide bars. Upon operation of a merchandise release lever, a guide bar therefor slides through the guide means slot and pivots the guide means to a release position. This axially shifts the lockout release means post, which correspondingly moves the cam, which, in turn, moves the cam follower and slides the slide. If the slide is not unlatched, the guide means cannot pivot and release of merchandise is precluded. Each merchandise release lever has a wedge element connected to it, which moves with the lever. A row of tabs is aligned next to the row of merchandise release levers. Upon operation of one of these levers, its wedge moves between neighboring tabs, causes the tabs in the row to separate and enables the tabs to block operation of other merchandise release levers in the row. There are also vertical tabs between neighboring horizontal rows of merchandise release levers. Upon the tabs in one horizontal row shifting sideways, one moves between two neighboring vertical tabs and shifts all the vertical tabs vertically away from their initial positions. The now shifted vertical tabs contact each horizontal row of vertical tabs, shift the horizontal tabs of each of those rows and prevent any other merchandise release lever in every other row from being operated. A recycling cam device is associated with the totalizer and with the coin lockout device for recycling both back to the start position after each vend transaction. Collected coins travel to an escrow container which retains the coins until the completion of a vend transaction. The escrow container includes two pivoting doors, one leading to a coin return chute and the other leading to a coin collection receptacle upon vending of an item. The two pivoting doors meet at their free ends and are held together by a spring which joins them.
