A steam locomotive-whistle model and toy providing realism in appearance in sound and operation of a real locomotive, by responding to blowing effort by the mouth or of a balloon which operates parts to run the locomotive and to emit sounds exactly simulating those of a real locomotive. It includes a smokestack and detachable cover, simulating smoke, to prevent air from escaping through its inlet hole. Also it includes a rear air intake pipe which is blown by the mouth to force air into an air chamber, thence into air ports and a cylinder to cause a piston to move away from the air inlet end of the cylinder.
The present invention provides a smoke generator for a model train. The invention allows a toy locomotive to produce smoke as an actual train would, in a puffing pattern. The present achieves its purpose by manipulating the flow of air through a smoke generating housing with a fan and a blocking device.
A smoke generating unit for a model train that varies the rate of smoke produce in response to changes in the load on the model train. The smoke generating unit includes a housing, a smoke element and a motor driven fan. The housing can be formed of two sub-housings. The first sub-housing can contain the smoke generating element and the second housing can contain the fan. The smoke element can be a nickel chromium wire. An insulating gasket can be positioned between the sub-housings to thermally insulate the motorized fan from the heat generating element. The motorized fan is controlled by a microprocessor that can monitor the load on the train and control rotation of the fan to correspond to the load on the engine. The load on the train can be the voltage across the engine of the train or the speed at which the train is moving.
A sound producing vehicle exhaust system comprises a housing positionable over an exterior end of a vehicle tailpipe. A turbine has at least one support plate. The support plate is rotatable about a central axis of rotation with the housing and has a plurality of angular blades with interior ends coupled to the support plate for rotation there with. At least one facing disk is positioned within the housing adjacent to the turbine. A central axis is provided through the facing disk and support plate. At least one bearing pin is provided. The bearing pin rotatably couples the support plate to the facing disk. A plurality of apertures extend through the facing disk. In this manner exhaust gasses from a tailpipe will pass through the blades and create a turbine-like sound.
