Toy vehicle having spring-operated motor
First Claim
1. A toy vehicle whose spring-operated motor requires little strength to fully charge, said vehicle comprising:
- A. a chassis supporting front and rear wheels;
B. a car body resting on the chassis, the front of the body being hingedly connected on a pivot axis to the front end of the chassis whereby the rear thereof is raisable with respect to the rear end of the chassis within predetermined upper and lower limits, said body having a stop attached thereto having fingers which engage a ledge projecting from the rear wall of the chassis to define said upper limit;
C. a spring-operated motor seated on the chassis and concealed by the body, said motor having a spiral spring coupled by a transmission to said rear wheels;
D. a pivotally-mounted crank arm operatively coupled to the underside of the roof of the car body at a point intermediate the front and rear wheels and spring-biased to normally hold the arm erect to maintain the body at its upper limit, whereby when the body is repeatedly depressed manually by a hand grasping the body near the rear thereof, the hinged body is caused to swing about its pivot axis and the crank arm undergoes a pumping action; and
E. means coupling said crank arm to the inner end of the spiral spring to effect winding thereof each time the arm is pumped.

Abstract
A toy vehicle having a spring-operated clockworks motor which is charged by a pumping action, the vehicle having a chassis on whose front and rear ends are supported front and rear wheel axles, and a body resting on the chassis. The front of the body is hinged to the front end of the chassis, a stop being provided whereby the back of the body is liftable with respect to the rear end of the chassis within fixed limits. The clockworks motor, which includes a spiral spring, is mounted on the chassis and is operatively coupled to the rear wheel axle, the motor having a spring-biased crank arm which engages the underside of the body and acts to normally raise the back thereof to its upper limit. The crank arm is operatively coupled to the spiral spring whereby by repeatedly depressing the back of the pivoted body while holding the vehicle to prevent rotation of the rear wheels, the crank is reciprocated to produce a rotary motion to wind the spring and thereby charge the motor. The charged motor acts to propel the vehicle when it is released.
