Mechanical Ride Thumber Speeds Hitch-Hikers Across Country (Feb, 1938)
Mechanical Ride Thumber Speeds Hitch-Hikers Across Country
CREDIT for their crossing of the continent in twenty-seven days is given by two Maine college students to the odd mechanical thumber which they used to hitch auto rides. A wooden hand with thumb extended is pivoted to a metal destination sign supported by a hollow pole. Pulling a wire operates a spring to jerk the hand in the approved hitch-hiker’s gesture.
