ABSTRACT:
The present invention involves a toy bubble blowing machine which has a housing which forms at least a part of a toy. The housing may simulate a motor and may be mounted on a ridable toy such as a bicycle, tricycle, toy auto, or the like. The toy bubble blowing machine includes a drive axle and a motive power source connected to, and capable of, driving the drive axle. The motive power source may be a battery operated motor and batteries or may be direct drive through gears, pulleys, or otherwise from the axle of wheels on a ridable toy. The bubble blowing machine also includes a bubble wand which has a plurality of wand heads with bubble forming orifices and a central hub. The wand heads are arranged symmetrically and concentrically above the hub and a hub axle extends from the hub. A Geneva mechanism is used which has a first gear which is continuously rotatable and a second gear which is a step gear and is rotatable through an arc intermittently. The first gear and the second gear are interconnected and the first gear is driven either directly or indirectly by the drive axle and the second gear is located on the hub axle itself so as to permit the motive power source to drive the bubble wand intermittently and so as to sequentially rotate each of the wand heads through a bubble liquid source position and through a bubble blowing position. There is a bubble liquid source located below the hub to permit rotation of the wand heads through it and there is also an impeller which is capable of blowing adequate air movement through one of the wand heads to create bubbles. The impeller is driveably connected to, and driven by, the motive power source. Finally, the present invention device includes a shutter which has a first position to block air movement created by the impeller from impinging on any wand heads while the wand is in motion and a second position to permit air movement to impinge upon the wand head to make bubbles while the wand head is not in motion. This is achieved by an abrupt drop off cam lift arrangement which operates the shutter.
