SOAlE-BUBBLE-BLOWING DEVICE.

To all whom it may concern Be it known that I, GEORGE M. LrrTLn, a citizen of the United States, residing at Pittsburgh, Allegheny county, State of Pennsylvania, have invented a new and useful Improvement in Soap-Bubble-Blowing Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in wh1ch- Figure 1 is a perspective View partially 1n sectien of one form of my soap-bubbleblowing device; Fig. 2 is a longitudinal section of Fig. 1; Fig. 3 is a sectional view on the line III-111 of Fig. 2; and Fig. 4 is a sectional view similar to Fig. 2 of another form of soap-bubble-blowing device. This invention relates to an improvement in soapbubble-blowing devices which can be cheaply and readily constructed and with which bubbles of large diameter and of beautiful'colors can be quickly blown.

One of the objects of my invention is to i provide a device having a bubbleblowing opening of large diameter, together With means for quickly introducing a large amount of air into the bubble being blown, so as to blow the bubble before much evaporation takes place.

Another object is to provide a device with a damper or check which will materially retard the exhaustion of the bubble when the blower takes another breath to increase the size of the bubble, and which check device will also act as a diffuser to break up the direct blast of air, so that the air will be distributed equally throughout all portions of the blowing opening.

A further object is to surround the blowing opening with a liquid container for feeding liquid to the bubble during the blowing operation, and thereby avoid the thinning of the film to the breaking point before a bubble of large size has been blown.

, The precise nature of my invention will be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that various changes may be made in the details of construction of the several parts, without departing from the spirit and scope of my invention as defined in the appended claims.

Referring to Figs. 1 to 3, the numeral 2- designates the body of the blower, which is Specification of Letters Patent.

of a conical form. lhe smaller end is provided with a mouth piece 3, having an openmg therethrough which is arranged to be Patented Nov. 3, 1914. Application filed August 6, 1913; Serial No. 783,364. i

inserted'through the larger end, so thatit can readily be changed when the blower is to be used by different persons. The larger or bubble blowin'g end of the device is provided with an absorbent rim 4, which may be formed of any material capable of absorbing and holding soapy water, and which may be attached to the end in any desired manner, such as by a waterproofcement.

The numeral 5 designates a damper which I have shown in the form of a screen and which is inserted in the blower between its ends, and is designed to break upjthe, currents of air from which the bubble is blown,

and also to form a damper or checking device to prevent the bubble from exhausting rapidly when the blower takes another breath. Extending through the wall of the blowing device between the end containing the mouth piece and the damper 5 isan opening 6, which is of verylarge diameter ,and' may be approximately the size. ofthe bubble-blowing opening. i

The damper o and the mouth piece 3 are made removable so. that both the. body portions and the dampers can be stacked to occupy a minimum amount of space during shipment and. storing. The damper 5 may be formed from wire screening whichpis pressed into suitable shape, or may be formed of textile material of very coarse open mesh which will be provided with a reinforcing ring of the proper shape. This damper also acts as a reinforce to retain the body in proper shape when in use. If desired, the entire body may be formed of an absorbent material such as felt or fabric of any kind, but for economy, I prefer to form the body of tin or waterproofed paper and attach tot-he bubble-blowing end a tape of absorbent material. I i

In Fig. 4, I have shown a one-piece construction similar to that shown in Figs. 1, 2 and 3, which is formed of suitable material and is provided with an integral mouth piece having an opening therethrough. In

this form, 2 designates the body, 3 the mouth piece, and 3 a tube extending inwardly from the end of-the mouth piece.

The operation of the device is as follows: a solution of soap in water is first made up in any suitable receptacle and the tape 4: is dipped into the solution. It is then re moved from the solution, a film of solution closing the opening. The operator then blows through the mouth piece, and during the blowing, air will be sucked in through the opening 6 by means of the injector action, which air, together with the air blown through the mouth piece, will pass through the damper 5 and will be broken up, so that the pressure of air will be approximately equal at all points on the bubble-blowing end as it passes to the bubble being blown. As the operator takes another breath, the damper 5 will prevent, in great measure, the escape of air from the bubble, so that it will not be materially reduced in size during the several intervals of time that the operator is not blowing. During the blowing operation, the bubble will draw water from the tape 4, and thereby prevent the film from thinning out to the bursting point before a large bubble has been blown.

I prefer to make the blower of general conical form, although good results may be obtained from blowing devices made of different forms.

The advantages of my invention result from the provision of a blower having a large bubble-blowing opening, together with an air inlet opening of large area between the bubble-blowing end and the mouth piece. Further, from the provision of a damper for breaking up the blasts of air and also for minimizing the escape of air from the bubble between breaths of the blower. Further, from the provision of means for supplying liquid to the bubble during the blowing operation.

I claim:

1. A bubble-blowing device of taper form, having a large bubble-blowing opening at one end, there being a small opening through the other end, and also an auxiliary air-supplying opening of large diameter through the wall of the device between the ends thereof, substantially as described.

2. A bubble-blowing device having a large bubble-blowing opening at one end, there being a small opening through the other end, there also being an air-suppplying opening of large diameter through the wall of the device and between the ends thereof, and a damper between the bubble-blowing end-and the last named opening, substantially as described.

3. A bubble-blowing device having a bubble-blowing opening at one end, a mouth piece having an opening through the other end, an air-supply opening of large area between the ends, and a screen between the airsupply opening and the bubble-blowing end, substantially as described.

l. A bubble-blowing device having a bubble-blowingopening at one end, a mouth piece having an opening through the other end, an air-supply opening of large area between the ends, and a removable screen between the air-supply opening and the bubble-blowing end, substantially as described.

5. A bubble-blowing device having a bubble-blowing opening at one end, a removable mouth piece having an opening through the other end, an air-supply opening of large area between the ends, and a removable screen between the air-supply opening and the bubble-blowing end, substantially as described.

6. A bubble-blowing device having a bubble-blowing opening at one end, a primary air inlet, a secondary air inlet of larger area, and an impedance between the secondary air inlet and the bubble-blowing opening; substantially as described.

In testimony whereof, I have hereunto set my hand.
