Toy car with rubber band motor
First Claim
1. A toy automobile comprising in combination, a body, an axle supporting a pair of freely rotatable wheels adjacent one end of said body and a second axle having a pair of wheels fixed thereto and connected to the opposite end of said body to drive the same, the improvement comprising motor means to drive said second axle and including, an elongated elastic member connected at one end to fixed means adjacent one end of said body and the opposite end being connected to a winding mechanism comprising;
- an elongated rack supported within said body for longitudinal reciprocating movement in opposite directions relative to said body and winding mechanism, a gear train mounted within a supporting frame in said body and including a drive gear fixedly connected to said second axle and a driven gear in the train connected to a short drive shaft mounted axially in said supporting frame and parallel to said rack and having means on one end connected to said opposite end of said elastic member, a throwout gear operable relative to said rack and mounted for engagement and disengagement with said drive gear, and transfer gear freely rotatable on said second axle and meshing with said driven gear, and a clutch mounted between said drive gear and transfer gear and having engageable ratchet teeth thereon operable when said rack is pulled outwardly to engage each other and drive said drive shaft to wind said elastic member and when said rack is pushed into said body said throwout gear is moved by said rack to disengage said drive gear, while said drive shaft remains stationary to retain said elastic member against unwinding.

Abstract
A toy automobile having front and rear axles on a body respectively supporting wheels, one of the axles being driven by a gear train energized by a twisted elongated member such as a rubber band, the elastic member being energized by twisting it by means of a reciprocable elongated rack extendable axially in opposite directions relative to the body of the automobile, which rack when pulled outwardly actuating the gear train to wind a drive shaft for the elastic member and, when the rack is pushed in retraction into the body, a throwout gear in the train is disconnected to prevent unwinding the elastic member, and a manually operable stop member engages the drive axle to prevent movement thereof until released.
