Abstract
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.
Claims18
A puffing smoke unit for a model toy train comprising:
- a smoke generator including an inlet hole and an exhaust hole;
- a fan to direct an airstream through the smoke generator;
- and
- a blocker movable between an open position and a closed position to intermittently restrict the airstream with respect to the smoke generator, the fan operable to direct the airstream with respect to the smoke generator when the blocker is in the open and closed positions.

A method of creating a puffing action in a model toy train comprising the steps of:
- generating smoke with a smoke generator including an inlet hole and an exhaust hole;
- directing an airstream through the smoke generator with a fan;
- and
- intermittently restricting the airstream with respect to the smoke generator with a blocker movable between an open position and a closed position, the fan operable to direct the airstream with respect to the smoke generator when the blocker is in the open and closed positions.
1 more element
A puffing smoke unit for a model toy train comprising:
- a smoke generator including an a housing, an inlet aperture and an exhaust aperture, smoke generated internal with respect to the housing;
- a fan positionable with respect to the housing to direct an airstream through the housing;
- and
- a blocker movable between an open position and a closed position to intermittently restrict the airstream with respect to the housing of the smoke generator, the fan operable to direct the airstream with respect to the housing when the blocker is in the open and closed positions.
