ATTORNEYS United States Patent Ofifice Patented June 14, 1955 This invention relates to a whistle and more especially If to a bubble whistle adapted to be used with a bubble forming solution whereby an operator may blow through the whistle and cause bubbles to be formed on the end thereof and a shrill sound to be emitted therefrom.

It is an object of this invention to provide an improved whistle having a flange or lip portion around one end thereof adapted to receive a film of bubble forming slu-- tion and being provided with a mouthpiece and a whistle opening therein whereby an operator may dip the bubble whistle into a bubble forming solution and by blowing through the mouthpiece may cause a bubble to be formed on the end of the whistle and sound to be emitted from the whistle opening.

It is another object of this invention to provide a bubble whistle of the type described having a cylindrical body portion provided with a whistle opening in the upper portion thereof and a mouthpiece at one end thereof and an annular lip at the other end thereof and the interior portion of said whistle between the lip portion and the whistle opening being provided with a baflle to form a restricted aperture or orifice therein, whereby an operator may blow into the mouthpiece and the restricted aperture will allow some air to pass through the body of the bubble whistle to form a bubble from bubble solution disposed on the lip portion thereof while most of the air will be restricted by the baflie and will be emitted through the whistle opening in the top of the bubble whistle to cause a shrill sound.

It is another object of this invention to provide a bubble whistle of the type described which may be formed cheaply and economically from a pair of complementary members precision molded from plastic and the like.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings in which- Figure 1 is a side elevation of the preferred embodiment of the improved bubble whistle;

Figure 2 is a top plan view of the improved bubble whistle;

Figure 3 is a longitudinal sectional view of the improved bubble whistle taken along the line 3-3 in Figure 2;

Figure 4 is an end view looking at the left-hand end of the bubble whistle shown in Figure 1;

Figure 5 is an end view looking at the right-hand end of the bubble whistle shown in Figure 1;

Figure 6 is a cross-sectional view of the bubble whistle looking along the line 6-6 in Figure 3 and showing the baflie means forming a restricted aperture in the body of the whistle;

Figure 7 is an exploded longitudinal sectional view similar to Figure 3 but showing a slightly modified form of bubble whistle;

Figure 8 is a vertical sectional view through the modified form of whistle shown in Figure 7 and taken substantially along the line 8-8 in Figure 7 but showing the upper and lower sections of the bubble whistle in juxtaposed or assembled position.

Referring more specifically to the drawings, the numeral 10 broadly designates a bubble whistle which is a very attractive and ornamental toy and which is so. constructed as to permit one end of the same to be dipped I into bubble forming solution so that an operator may blow through the same and the required amount of air will reach the end of the whistle to form a bubble thereon and some of the air blown thereinto will be emitted from a whistle opening therein to emit a whistling sound.

The bubble whistle 10. is preferably formed from two complementary portions 11 and 12 which form the upper and lower halves, respectively, of the bubble whistle and which are preferably molded from plastic but which may i be molded or formed in any suitable manner from any suitable material. By constructing the bubble whistle in this manner, the two complementary'members 11 and 12 may be formed by precision molding and secured to: gether by any suitable means such as adhesive to form a bubble whistle which has all of the characteristics of a hand machined instrument but which may be quickly and economically produced to form a pleasing and inexpensive toy with the characteristics of a precision instrument.

The upper member 11 and the lower member 12 form a bubble whistle having a body portion 13 in the form of a cylinder having an annular flange or lip portion 15, molded integral with one-end thereof. The end of the body portion 13 opposed from the lip 15 is reduced as at 16 due to the lower wall of the member 12 being slanted, and this reduced portion 16 merges into a mouthpiece 17 preferably being provided with a suitable flange or lip 18 thereon. The walls of the mouth piece 17 are of such a thickness as to provide a passageway 20 there-.

between when the upper and lower pieces 11 and 12 are secured together.

The upper member 11 is provided with a whistle opening 21 directly above the slanted wall or reduced portion 16 of the lower member 13 and this whistle opening 21 has an inwardly inclined plate 22 molded integral with one side thereof and it will be observed in Figure 3 that the plate 22 extends inwardly and stops short of thewall of the opening-21 and in substantial alinement with the passageway 20. It will be readily observed that this arrangement of the slanting plate 22 is such as to cause the greater portion of air blown through the passageway 20 to be deflected upwardly and out through the whistle opening 21 and to cause only a portion of said air to pass into the body portion of the whistle. It should be noted that the distance between the free end of the slanting plate 22 and the wall of the whistle opening 21 adjacent the passageway 20 is relatively small.

In order that the correct amount of air may reach the end of the whistle having the flange 15 therearound, it is necessary to provide a bafiie in the body of the whistle to restrict the amount of air flowing therethrough. It has been found that when this battle is omitted too much air will flow through the body 13 of the whistle which will cause bubble forming solution deposited on the end whistle, an insuflicient amount of air will be emitted through the whistle opening 21 to cause a noise to be emitted therefrom. It is therefore seen that the baffle in the present invention is of particular importance as this bafiie together with the other features of the inven tion will cause the proper amount of air to flow through the whistle and the proper amount of air to be emitted through the whistle opening 21 for the most satisfactory operation.

Referring to Figures 3 and 6, there will be observed a preferred form of bathe in the form of a pair of semicircular plates 25 and 26, the plate 25 being secured to or molded integral with the upper portion 11 of the whistle and the plate 26 being molded to or secured integral with the lower portion 12 of the whistle 10 and it will be observed that the proximate edges of the plates 25 and 26 stop substantially short of each other to provide an opening therebetween. It will also be observed that the plates 25 and 26 are disposed in staggered relation to each other to more effectively limit the flow of air therethrough.

Referring to Figure 3, it will be observed that a substantial portion of air passing through the passageway will be deflected by the slanting plate 22 and will be emitted through the opening 21 to cause a whistling noise and the remaining portion of the air will be deflected downwardly along the slanting wall 16 forming the reduced portion of the whistle and will thus then be deflected upwardly against the baffies 25 and 26 and a small portion of air will flow through the opening between the battles 25 and 26 and out the end of the whistle having a lip 15 thereon.

In operation, the lip portion 15 of the whistle 10 may be dipped into a bubble forming solution and it will be observed that the lip 15 is substantially dish-shaped so that a thin film of solution will be retained thereby and will extend over the open end of the body portion 13 of the whistle and upon air being passed through the whistle in the manner just described, a small amount of air will flow against the film disposed on the lip portion 15 and will distend the same to form a bubble. By varying the amount of air being blown through the passageway 20, an operator may vary the size of the bubble formed on the end of the whistle and may also vary the shrillness and volume of the whistle emitted from the whistle opening 21.

Referring to Figures 7 and 8, there will be observed a slightly modified form of bubble whistle wherein all the parts are identical to the parts in the bubble whistle 10 heretofore described, with the exception of the bafile disposed in the body portion 13 of the whistle. The modified form of whistle is indicated at 10' and like parts will bear like reference characters with the prime notation added.

It will be observed that in the modified form, the baffle is formed of two coinciding plates 31 and 32, the plate 31 being secured to or formed integral with the upper member 11' and the plate 32 being formed integral with or secured to the lower member 12'. Each of the baflie plates 31 and 32 has a semi-circular concavity 33 and 34, respectively, in the center portion thereof so that when the parts 11 and 12 of the whistle are secured together, the plates 31 and 32 will form a substantially circular plate having a circular bore indicated at 35 in Figure 8 therein. The proximate edges of the plates 31 and 32 coincide so as to permit air to pass only through the bore 35.

Referring to Figure 7, it will be observed that the upper portion 11 of the whistle 10' preferably has one or more concavities therein adapted to receive coincidingly positioned projections 41 on the portion 12' of the whistle 10' to assist in securing the parts together and to assure correct alinement of the portions 11 and 12 relative to each other when the whistle is assembled. It is preferred that the original form of the invention illustrated in Figures 1 to 6, inclusive, also be provided with concavities and projections similar to the concavities 40 and projections 41 for like purposes.

In the drawings and specification, there has been set forth a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claim.

I claim:

A bubble blowing whistle comprising a tubular member open at one end and having a mouthpiece integral with its other end provided with a longitudinally extending passageway, said tubular member being provided with an orifice at the junction point of the tubular member and the mouthpiece, said tubular member being provided with an inclined wall terminating adjacent the mouthpiece and in alinement with the longitudinally extending passageway in the mouthpiece and having an opening between the free end of the inclined wall and the mouthpiece, the free end of the inclined wall serving to divide the stream of air forced through the mouthpiece to produce an audible sound, said tubular member having a pair of spaced internal transversely disposed ribs spaced from the inclined wall and also spaced from the open end of the tubular member to reduce the intensity of air as it emerges from the open end of the mouthpiece and the open end of the tubular member having an enlarged flange portion integral therewith which is frusto-conieal in cross section.
