MOUTHPIECE FOR USE IN BLOWING SOAP BUBBLES.

Application filed August 22, 1922. Serial No. 583,635.

To all whom it may concern:

Be it known that I, RUnoLr LARsEN, mcchanician, a subject of the King of Denmark, residing at 47 Bohmensgade, Copenhagen, Denmark, have invented certain new and useful Improvements in Mouthpieces for Use in BlowingSoap Bubbles; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

The invention is a mouth piece to be used in blowin ter to be blown up to far larger dimensions than practicable by the usual use of a clay pipe as mouth piece.

One embodiment of the invention is illustrated on the drawing.

Figure 1 showing the mouth piece in top view'(in the direction of blowing) and Figure 2 the same in axial section.

The device consists of aconical or essentially conical blow-pipe a inserted through a central circular aperture in a circular disc 7), and pressed firmly against a short conical flange 0 projecting from the disc. The disc forms a number of radially projecting arms (5 which are shown on the drawing, to be in tcrconnectcd by a circular ring 0, which lat- *ter acts as a bracing but may really just as well be dispensed with. The disc may also normally be considered as a plane flat wheel of which the flange c is the hub, the arms d the spokes, and the circular ring e 'the felloc. i i

The device is used in the following manner: When the blow pipe a has been placed in position in the flange o, it is gripped by the lingers, and the entire disc is then dipped into soap water, preferably with admixture of some substance facilitating the formation and conservation of the film. When next the tube is blown into, the soap bubble extending from the flange 0 will to very big soap bubbles and enables the latspread itself along the arms d and find sup port along The soap bubble may thereforebe blown up dimensions and, after some slight experience, be easily released by means of the disc being withdrawn in tangential direction relatively to the bubble.

It will easily be seen to be of importance to the efficiency that the parts of the disc should mainly be directed radially, as the expansion of the bubble in radial direction the latter with great tenacity.

will be obstructed by the presence of circumferentially directed parts. Besides of metal the device may be manufactured to advantage of celluloid and many other substances of similar nature.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. In a device for blowing soap bubbles,

the combination with a blowing tube widening towards its blowing orifice; of a disk having a center hub adapted to fit around said orifice, an outer rim, and having a plurality of slots extending from said hub to said rim, substantially as described.

2. A month piece for blowing soap bubbles, comprising a blow pipe, a disk-shaped member attached to the discharge end of the blow pipe and provided with radial slots alternating with radial arms or spokes and an outer ring.

3. A month piece for blowing soap bubbles comprising a tubular blow pipe, a disk having a center hub adapted to fit, around the discharge end of said blow outer rim on said disk, and having a plurality of slots extending from said hub to said rim.

In testimony that I claim the foregoing as my own, I afiix my signature.

RUDOLF LAB-SEN.
