  • Time lapse steering controls for self propelled models
    Patent number: 4041886
    Abstract: This invention relates to a time lapse steering control for models of the type which causes a self propelled model car, boat, or airplane to alter its course of travel after a certain preset period of time has elapsed. In one embodiment of the invention this is accomplished by using a patented air bleed timer which serves three functions:1. It determines at what point in time the course of travel will be altered;2. It determines the extent of the turn; and3. It provides the propelling force which moves a cam past a cam follower. The cam follower in turn actuates the linkage which is coupled to the steering member of the model.
