REMOTE CONTROL LOCKS CASH DRAWER (Sep, 1934)
Seems like this would be easy to defeat by simply saying to the teller: “If you press that button I’m going to shoot you in the head.”
REMOTE CONTROL LOCKS CASH DRAWER
Designed to be proof against holdups, a remote-control cash drawer has been introduced. When a bandit appears, the storekeeper has only to press a concealed foot button to lock the drawer electrically. It cannot then be opened until a key is brought from a distant place and used in combination with the regular key. The drawer is made of heavy steel plate and is securely bolted to the counter so that it cannot be pried open or carried away. Another innovation is a money locker equipped with a delayed timing control that opens it just fifteen minutes after the combination is set. There is no way to hasten the action. Signs conspicuously posted warn bandits a hold-up would be useless.
