Patent number: 4418551Abstract: The cash box of a vending machine is protected by a heavy steel door or pair of doors which are locked across the front of the juke box covering the cash box, the door or doors being mounted on a framework consisting of steel straps which wrap around the back, and preferably the top and bottom as well, of the vending machine and interlock in such a way that they can be installed without screws, bolts or other fastening structure and will positively be locked into place when the barrier door or doors are closed. This configuration eliminates the need to mount a barrier door onto the vending machine, which is somewhat time consuming and tricky due to the strength of the mounting that is required.Type: GrantFiled: July 6, 1981Date of Patent: December 6, 1983Inventor: Donald G.
