ABSTRACT:
A free-wheeling toy vehicle which when propelled makes a repetitive sound simulating the noise of an internal combustion engine. The vehicle includes a chassis having bearings supporting front and rear wheel axles. Lying on top of the chassis between the axles is a drum having an elastic drum head. Cantilevered from one end of the chassis is a clapper formed of a flat metal spring terminating in a striker, the spring being biased so that the striker normally rests on the drum head. A finger projects downwardly from the clapper, the tip of the finger being successively engaged by the equispaced teeth of a hub mounted on one of the wheel axles and turning therewith. Each time the finger tip is engaged by a moving tooth, the finger is pushed forward to raise the striker above the drum head; and when the finger than falls between adjacent teeth, the striker is released to hit the drum head to generate a thumping sound. The repetition rate of the clapper action depends on the running speed of the vehicle and therefore acts to create a realistic motor noise.
