Application June 15, 1937, Serial No. 148,333

1 (Claim.

- the orifice of the blower before the bubble is formed.

Another object of the invention is to provide, in a device of the character described above, a

reservoir which renders the blower capable of.

forming a series of bubbles without reloading, or which also renders the blower capable of discharging a shower of separate bubbles at the option of detailed description of the invention hereunto annexed.

It is to be understood that the invention is not to be limited to the particular species thereof shown and described as various other embodiments thereof maybe employed within the scope of the appended claim.

Referring to the drawing:'

Figure 1 is a perspective view, with a portion thereof broken away so as to more clearly disclose the interior construction, of a bubble blower constructed in accordance with the principles of this invention.

Figure 2 is a perspective view of the bubble supporter.

In detail, the "bubble blower of my invention comprises a length of cardboard tubing 3 which-is impregnated with paramn, or other similar ma-- terial insoluble in water, so as to render it waterproof. Into the end 4 of the tube, which is the end at which the bubbles are formed, is placed a piece of sheet metal 5 bent to substantially tubular form and provided with corrugations 6 which provide, in coniunctionwith the inner periphery.

of the tubing, a. plurality of small passages I dis posed axially parallel with the axis of the tubing. Adjacent the opposite end 8 of the tube, which is the end into which the user'blows, is provided a plurality of bleeder apertures '9 which extend entirely through the tubing side wall. The purpose of these apertures is to bleed ofi some of the pressure created by blowing into the tube so that the film of soapsolution covering the end Q will not be flexed so suddenly as to cause it to rupture before the bubble is formed.

When the end d of the tube is dipped into a solution of soap and water some of the solution will be drawn, by capillary attraction, upwardly into each of the passages l and when the tube is withdrawn from the solution a film of the latter will cover its end. The end 8 of the tube is then brought adjacent the lips andby blowing steadily into this end the bubble will be formed which, when it reaches a certain size will drop from the end of the blower still leaving a' film of soap .solution covering the end. As successive bubbles are blown the solution contained in each of the passages will flow therefrom to form the films cov- 'ering the blower end as each formed bubble is dropped or shaken from the blower. The provisupply of solution in the reservoir has been dissipated to the point where the film across the end of the blower will not be formed when the last bubble of a series has been blown or if the film is ruptured by the creation of too great a pressure in the blower tube, the user may obtain a novel effect by creating a strong draught through the tube which will pass through each of the passages l causing any solution contained therein to-b'e' ejected and thereby causing'a shower of small bubbles to be discharged.

' The size of the bubble which may be formed with the blower of my invention is limited by the size of the tube at the discharge end d which presents only a certain area which the bubble may cling to. While the bubbles formed with the blower are sufllciently large for most intents and purposes I have found that by the provision of asirnple attachment for theend of the blower the diameter reached by the bubbles before they willdrop from the blower end is materially in. creased. This attachment is shown in Figure 2 and comprises a length of wire bent to form a loop II the opposite ends of the wire beingthen directed radially outward and bent upwardly to"- provide a pair of spaced parallelarms I2. The attachment is connected with the blower as shown .by the dot and dash lines of Figure 1, the

arms-l2 being inserted in apair of the passages Y I the loop H belng then disposed spaced relation with the end of the blower. When the bubble is blown it will be in contact with the loop I I of the at chment which, being of a larger diameter than t e end of the blower permits the bubble to attain a much greater size before it will drop of its own weight from the loop.

. The attachment just described permits of the attainment of novel. eflects not attainable with ordinary bubble blowers. It will be noted in Fl' ure 1 that the center of the loop ii is oiiset slightly from the axis of the blower tube. This permits the user, after a bubble has been formed on the attachment and while the bubble is still connected therewith to insert a smaller tube, such as a soda straw, which has been previously dipped in the soap solution, into the bubble through the film within the loop ll so that upon blowing into the smaller tiibe one or more smaller bubbles will be i'ormed within the main larger bubble. T0 attempt to do this without the attachment would result. in bursting oi the bubble. It appears that the reason that the bubble does not burst when thesmallertubeisinsertedthroughtheloop Ii is that the dim oi. soap solution within the loop is thicker than that forming the rest of the bubble.v

tube, said corrugations o! the sheet material cooperating in conjunction with the inner periphery of the tube to provide a plurality of passages in and opening at the end of the tube, and a wire member bent to form a loop positioned at the end of said tube,'said wire member having arms extending therefrom slidably engaged in said passages.
