<p>TITLE: TOY SIMULATING STEAM LOCOMOTIVE A toy steam locomotive is described which includes a small electric motor which drives an apparatus for producing a sound simulating a steam locomotive, an apparatus for producing a sound simulating a steam locomotive whistle, and an apparatus for producing a visual simulation of a fire in a steam locomotive firebox. The apparatus for producing a simulated steam locomotive sound includes a resonator and a vibrating spring. A cycling member is attached to the spring and concurrently tenses and relaxes, lengthens and shortens and associates and disassociates said spring with a sound activating member. The apparatus for producing the sound simulating a steam locomotive whistle includes a housing having a fan located therein and an air inlet and air outlet. The air outlet is associated with a whistle and a sealing member seals the air inlet, but allows air to be drawn into the housing when the sealing member moves away from the air inlet. The apparatus for producing a visual simulation of a fire includes a flat transparent member having a plurality of ridges on one of its planar surfaces and a movable member located behind the transparent member. The movable member oscillates back and forth such that at least a two colored flame-like pattern on its surface is distorted by the ridges of the transparent member simulating a fire.</p> |
