BUBBLE BLOWER Filed Jan. 6, 1950 Patented July 24, 1951 BUBBLE BLOWER Arthur R. 'Corbitt, Charlotte, N. 0., assignor of forty per cent to T. H. Lever, Sr., Charlotte, N. C.

Application January 6, 1950, Serial No. 137,139

2 Claims.

This invention relates to a novel construction of bubble blower for use as a toy by children and by the use of which a relatively large number of bubbles may be blown with the device without replenishing the supply of soapy liquid employed.

Still a further aim of the invention is to provide a device which may be adjusted readily for blowing bubbles of different sizes and which is so constructed that the bubbles may not be readily broken while being blown and which will prevent the soapyliquid from being expelled from the device otherwise than in the form of bubbles.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereofland wherein:

Figure 1 is a side elevational view of the bubble blower;

Figure 2 is an enlarged longitudinal sectional view thereof taken substantially along a plane as indicated by the line 2-2 of Figure 1, and

Figure 3 is an end elevational view looking from right to left of Figure 1.

Referring more specifically to the drawing, the bubble blower in its entirety is designated generally 5 and may be formed of any suitable material which is relatively light in weight, as for example a plastic, and may be made in various colors or color combinations.

The bubble blower 5 includes a head, designated generally 6 and a tubular stem, designated gener ally 1. The head 6 is preferably cylindrical in cross section and has an open end 8 and is provided at its opposite end with an end wall 9 which constitutes an integral part thereof. The end wall 9 is provided with a central opening l0 which is sized to receive and closely engage a portion of the tube 1. The tube 1 may be engaged sufficiently snug in the opening I0 to retain it against movement relatively to the head 6 but is preferably so engaged that the tube I may be reciprocated in the opening I0 relatively to the head 6, for a purpose which will hereinafter become apparent. The end wall 9 is also provided with a plurality, preferably four, apertures l l which are equally spaced from one another and from the opening I0. As illustrated in Figures 2 and 3, the apertures H are each considerably larger in diameter than the opening l0 and are each of a substantially greater diameter than the bore 12 of the tube 1.

v For best results, the head 6 is made one and one-eighth inches in length and seven-eighths of an inch in diameter externally and the apertures H thereof are preferably made three-sixteenths of an inch in diameter. The tube I preferably has an internal diameter of approximately one-six-' teenth of an inch and may be made in various lengths, as for example about four inches and for blowing bubbles of medium size, the tube 1 extends three-eighths of an inch into the head or bowl 6. The further the stem is extended into the head 6 the smaller will be the bubbles produced and conversely, the shorter distance that the stem extends into said head the larger will be the bubbles which will be blown.

To use the bubble blower, the open end 8 of the head or bowl 6 is dipped into a soapy solution, not shown, such as is conventionally employed for bubble pipes and only far enough to gather a film of the solution across said open end 8. The mouth of the user is then applied to the outer end I3 of the tube 1 and air is blown gently through the tube 1 into the head 6. This will likewise cause air to be drawn into the head 6 through the apertures II and result in a large number of bubbles being blown substantially simultaneously. The admittance of the air through the apertures ll prevents the air being expelled into the head 6 from the tube 1 with suflicient force to expel thesoapy solution from the bowl end 8 without producing bubbles and makes it possible, by skillful operation of the bubble blower 5, to produce from seventy five to one hundred bubbles without replenishing the soapy filmi As previously stated, the user may vary the size of the bubbles by moving the tube 1 further into the head 6 for producing smaller bubbles or by retracting the tube outwardly of the head for producing larger bubbles.

Obviously, the bubble blower may be made in various sizes and the dimensions as specified may be varied and numerous other modifications and changes are likewise contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claims.

I claim as my invention:

1. A bubble blowing device consisting of a head and a tubular stem, the side wall of the stem being imperforate, said head being cylindrical in cross section and having an end wall at one end thereof and being provided with an opposite open end, said end wall having a central opening in snug engagement with a portion of the stem and supporting the stem on the head with one end of the stem extending into the head and terminating therein, said end wall being provided with a plurality of apertures spaced from and disposed 3 4 around the portion of the stem which is engaged by said end wall, said apertures individually being FEFERENCES CITED larger than the bore of the tubular stem The following references are of record in the 2.
