This paper analyzes a jettison device to be used when the driver foresees tractor jackknifing in logging tractor-trailers. This jettison device uses the simple concept of a shear-pin to disconnect the tractor from the trailer in case of an emergency, and also to drop the skid plates. The plates are guided by an antenna rod, so that they fall in front of the duals of the trailer. An actuating device releases the air from the air hoses connected to the air brake cylinder, so that the emergency brakes come on. It also turns on a flashing light to warn traffic. The device is so designed that it is inoperative if the tractor is going over 72 kmph, therefore insuring that the driver cannot use it on highways. (Kursetz)
