ONE-WHEEL TRUCK (Feb, 1959)
TRAILMOBILE, Inc., the nation’s second largest trailer builders, recently found plans of what may have been the granddaddy of all trailer-tractors—the “motor wheel” shown in the accompanying pictures. Manufactured more than 60 years ago by an outfit bravely styled the International Motor Wheel Co., it was invented by one J.W. Walters. The unit consisted of a rubber-tired wooden wheel propelled by a two-cylinder, air-cooled gasoline motor mounted with a heavy flywheel on one side of the fork; on the other side were twin gas tanks. The steering wheel turned the whole unit; to reverse, you turned it right around. Or you would have, if you’d had the chance to drive it. Few ever did. The idea of a petrol-eating horse for a wagon was great, but the motor of the period wasn’t.
