LITTA L. VOELCI-IERT, OF M'ANITOWOC, WISCONSIN.
Application filed July 5, 1919.
To all whom it may concern Be it known that I, LI'lTA L. VoELoI-InR'r, a citizen of the United States, residing at Manitowoc, county of Manitowoc, and State of Wisconsin, have invented new and useful Improvements in Bubble Blowers, of which the following is a specification.
My invention relates to improvements in bubble blowers.
The object of my invention is to provide a whistling bubble "blower capable of producing highly ornamental clusters and chains of bubbles which can be varied in form and arrangement by a simple substitution of interchangeable heads, each embodying my invention in slightly modified form.
Attempts have heretofore been made to provide bubble'blowers which will produce clusters of bubbles from a plurality of apertures, but, so far as I am aware, without success, except as to bubbles which are being formed at the apertures. This is due to the fact that the bubbles contact with each other and amalgamate, unless the apertures are so disposed as to substantially equalize the pressure of the outer bubbles upon the central ones, or unless the pressure of the outer bubbles, while expanding, is exerted in such a manneras to force the inner bubbles outwardly, the inner bubbles being formed in advance of the outer ones, and tending to leave the bubbler before the outer ones have been expanded to the point where delivery takes place. I
In the drawings Figure 1 is a side view of a bubble blower involving my invention, the stem and whistler being shown partly in section.
Figure 2 is a view of the outer end.
Figures 3 and 4 are side views showing interchangeable head pieces in modified construction.
Figures 5 and 6 are views of the outer surfaces respectively of the modified bubble blowers shown in Figures 3 and 4.
Figures 7, 8 and 9 are cap pieces, adapted to be interchangeably mounted upon the outer end of the bubble blower disclosed in Figure 4.
Like parts are identified by the same reference characters throughout the several views.
The stem 1 is an ordinary tubular stem, except that at its front or inner end it is provided with a notch 2 to provide anchorage for a suitable whistle 3, which preferas Specification of Letters Iatent.

bly constitutes the mouth piece, although this is not essential.
The whistle 3 may be of any ordinary type in which the air passes through the body of the whistle in such a manner that it can be delivered into the tubular stem 1.
The outer end of the stem is provided with a detachable head piece 4, which is illustrated in Figure 1 as having concavo conical walls, expanding laterally to an annular zone or line 5 beyond which the head piece is spherically rounded, as shown at 6, and provided with a central aperture 7 surrounded by a row of symmetrically arranged apertures 8, the latter being located near the line 5, whereby bubbles blown from the central aperture 7 will be beyond those blown from the annular row of apertures; The bubbles blown from the apertures in the annular row will therefore tend to push the other bubbles outwardly, and will contact with them only on their inner side. The pressure of the surrounding row of bubbles will therefore not be exerted to prevent the central bubbles from expanding longitudinally and also laterally in planes transverse to the axis of the stem, through their central portions. While the form of construction above described does not 1 entirely eliminate the tendency ofthe bubbles to am'algamate, it reduces such tendency to a minimum, and makes it possible; to blowsymmetrical groups and chains of bubbles, with substantial uniformity, of general design.
The concavo conical form of the inner portion of the head 4 is not essential to my invention, and it is also not essential that the central apertures be limited to a single aperture in line with the passage through the stem, as illustrated in Figures 1 and 2.
I11 Figures 3 and 5 I have illustrated a globular head 10? having three symmetrically grouped apertures 11, 12 and 13, arranged at substantially equal distances from a central point lying in the axial line of the stem projection. In this form of con struction I have also illustrated an annular row of apertures 15 which are located substantially in a line which lies in a great circle of the globe 10, and in a plane transverse to the stem. In this construction the bubbles blown from the three central apertures 11, 12 and 13 will have some tendency to amalgamate, and the unequal pressure of the annular 19W of bubbles surrounding them will have some tendency to twist the chain of bubbles delivered from the various apertures in the head. But owing to the fact that the central bubbles are located beyond those blown from the annular row of apertures 15, the tendency to amalgamate will be slight, and chains of bubbles may be produced, which will generally conform to a few leading designs.
In Figure at I have illustrated a head piece 20, which may be generally regarded as h aving a globular form, although it conforms largely to the shape of an ordinary pipe bowl having a single large aperture 21 on the outer side. This head piece 20 is also interchangeable with the head piece 10 and the head. piece t upon the same stem 1.
But it will be observed that I have pro vided a series of cap pieces 23, 24 and 25,
(Figures 7, 8 and 9), which may be interchangeably mounted to cover the aperture 21 in the head 20. The cap piece 23 has apertures arranged generally in the manner illustrated in Figures 3 and 5. But the surface in which these apertures are located is conical in form instead of being spherically rounded, as in Figures 3 and 5.
The cap piece 24: may have a spherically rounded surface, but the central aperture 28 is elongated or oval in form, and the surrounding apertures are not symmetrically grouped, there being two comparatively large apertures 29 on one side of the center of the cap, and a series of smaller apertures 30 on the opposite side, arranged along an arcuate line, whereby the general design of this cap is such as to crudely represent the eyes, nose, and mouth of a human face. The cap piece 25 shown in Figure 9 is formed in the design of a hat, the crown of which is rounded and provided with apertures grooved substantially as illustrated in Figure 3. When this cap piece is applied to the head piece 20 shown in Figure 7, the results produced are quite similar to those produced by the head piece illustrated in Figure 3, the difference being in the design of the head rather than in the results produced in the chain of bubbles.
\Vhile I have described the whistle as located in the mouth piece or inlet end of the stem, and while I have also described the stem as having its axis in line with the center of the head piece, and with the cert tral aperture in the head piece where the aperture is centrally located, I do not limit the scope of my invention to this lineal ar rangement of the stem, the head piece, and the central portion of its apertured wall, nor to any specific location of the whistle producing member, although I prefer to locate the whistle at the mouth piece or inlet, and I also prefer to have at least the outlet end of the stem or its outlet port so disposed as to direct the air across the central portion of the head toward the central portion of the apertured wall, for with this arrangement, the tendency will be to form bubbles a little faster at the central aperture or apertures than at the others which are laterally ofiset from the line along which the air travels through the head.
I claim A. bubble blower comprising a stem, a hollow head piece located at one end of said stem, said head piece having a portion of its surface spherical and provided with a phirality of spaced apertures located wholly within the spherical portion of said head piece.
In testimony whereof I afiix my signature in the presence of two witnesses.
