Abstract
A power take-off is provided for a model vehicle driven from a single "penlight" battery. The vehicle has a chassis (10) carrying an electric motor driving an axle (5) through a horiozntal worm (4) and worm gear. A cover (11) for the motor has a through hole for a shaft (12) carrying a lower pinion (13) engaged with the worm (9) and an upper pinion (14) that drives a take-off gear (15) provided with dog-clutch pins (16). A sliding gear (26) provides the second part (27) of the dog clutch and drives actuator cranks (37) of an output shaft (35). Thereby anciliary devices of the vehicle may be driven from the same motor that drives the wheels.
