Abstract
A system for remotely starting model toy internal combustion engines, used for propulsion of the model toy, such as an airplane, helicopter, boat, automobile, or other similar vehicles. The starter mechanism being contained in a single case, coupled to a single gear attached to the model engines crankshaft. The starter case being sufficiently small so as to allow it to be mounted directly to the model toys internal combustion engine. An electrical starter motor attached to the starter mechanism case, for cranking the engine, operating from the internal batteries on board the model toy. A remotely controlled servo starting circuit that energizes the engines ignitor plug, allowing sufficient preheat time, and activates the starter motor, from signals provided by the radio receiver on board the model toy vehicle.
Claims5
A system for starting a model toy internal combustion engine by means of remotely transmitted radio signals for use in model toy airplanes, helicopters, boats, automobiles and similar vehicles, comprising:
- (a) a case containing a starter transmission mechanism, said case including means for direct mounting of an electric starting motor
- (b) a mounting part for removably attaching said case to the body of said engine;
- and
- (c) a driven gear attached to the engine crankshaft, said starter transmission mechanism including a pinion gear movable into direct driving engagement with said driven gear.
In a system for starting a model toy internal combustion engine by means of remotely transmitted radio signals for use in model toy airplanes, helicopters, boats, automobiles and similar vehicles, a mechanism for coupling an electric starting motor to a driven gear attached to the engine crankshaft comprising:
- (a) a helix sleeve carrying a pinion gear moveable into engagement with said driven gear;
- (b) a shaft rotatable by said electric starting motor and carrying a drive pin operatively coupled to said helix sleeve;
- (c) a brake drum tightly journalled about said helix sleeve;
- and
- (d) adjustable brake means contacting said brake drum for restraining rotational movement of said helix sleeve so as to engage the pinion gear when said shaft is rotated.
