ABSTRACT:
An air driven sound generating toy includes a support base having a bellows housing secured thereto. A bellows chamber is supported within the bellows housing and is coupled to a collapsible resilient air bellows. A tube receptacle is supported by the base and operatively coupled to the bellows chamber. A pair of check valves are supported within the bellows chamber to provide a stream of pressurized air into the tube receptacle as the bellows is successively collapsed and expanded. An elongated hollow sounding tube includes opposed end portions each couplable to the tube receptacle in an alternative attachment. A quantity of malleable play material is received within the interior passage of the sound tube and is caused to move upwardly through the sound tube as the air bellows is operated to produce pressurized air within the tube receptacle and sound tube. In addition to moving the play material, the pressurized air is, in part, forced past the play material to produce an unusual and entertaining sound effect.
