ROBBER-PROOF CAR INVENTED

In Case of Holdup Fumes of Cyanide of Potassium Would Be Thrown in Faces of Robbers. It would be a sad gang of robbers who tried to break into the railway car invented by George W. Mej’ers of the United States army. They would be greeted with clouds of poisonous gas fumes. Meyers’ robber-proof car works with extreme simplicity. Two tanks, in which fumes of cyanide of potassium are stored under pressure, are fitted inside of the car at each end. These are connected with a perforated pipe which extends all around the door of the car, just in back of the outer framework. Should the train be held
