ABSTRACT:
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.
