Abstract: There is disclosed herein a toy bubble-blowing machine which includes a housing and an associated bubble-forming mechanism. The bubble-forming mechanism includes a plurality of elements, with only one--a hand crank--being positioned outside of the housing. The hand crank is rotatable and is connected to a main drive shaft and drive gear. A propeller which is positioned within the housing and above the drive shaft is drivingly interconnected with the drive gear by a gear train for rotation at a speed greater than the speed of the shaft. A bubble dipper is secured to the drive shaft for rotation through a reservoir of bubble-forming liquid within the housing and for forming a film of the bubble-forming liquid. As the dipper is rotated, the dipper positions the film in the airstream from the propeller so as to form bubbles from the film.
