Abstract
An augmented bubble blower device in which a mouthpiece tube is mounted for axial movement relative to a venturi tube. The discharge end of the tube is surrounded by an open chamber so that a jet of breath which is discharged from the mouthpiece tube along the longitudinal axis of the venturi tube draws air from the surrounding environment and carries that air with it into the venturi chamber. The remote end of the venturi chamber provides a support for the formation of a bubble from film-forming material stretched across the remote end of the venturi tube.
Claims9
An augmented bubble blower device comprising:
- a tubular member having a nozzle end for dicharging gas, an open chamber, a venturi chamber spaced from said nozzle end and having a longitudinal axis, said venturi chamber including in axial alignment a converging section adjacent said open chamber, a constricted throat section, and a diverging section, and means for slidable mounting said tubular member for movement along said longitudinal axis toward and away from said venturi chamber, said means for mounting positioning said tubular member so that said nozzle end is adapted to discharge gas into said open chamber toward said venturi chamber approximatly along said longitudinal axis whereby gas discharged from said nozzle end enters said venturi chamber and draws additional gas from said open chamber into said venturi chamber, and means for supporting a film of bubble forming material in position to receive gas after said gas passes through said diverging section.
An augmented bubble blower device comprising:
- a gas conduit member having a discharge end for discharging a stream of gas, an open chamber surrounding said discharge end, an enclosed constricting chamber spaced from said discharge end and having a large end and a small end, means supporting said discharge end for movement toward and away from said large end, said discharge end being adapted to discharge said stream of gas into said large end, whereby said stream of gas draws additional gas to it so that an augmented gas stream flows into said constricting chamber, and means for supporting a film of bubble forming material in position to receive said augmented gas stream after said augmented gas stream passes through said constricting chamber.
An augmented bubble blower device comprising:
- a tubular member having a discharge end for discharging gas, an open chamber surrounding said discharge end, an enclosed constricting chamber spaced from said discharge end and having a converging section with a large end and a small end, said discharge end being adapted to discharge gas into said large end, said tubular member being mounted for movement of said discharge end toward and away from said large end, and means for supporting a film of bubble forming material in position to receive said gas after said gas passes through said small end.
