BU BLE BLowER.

Application filed September To aZZ whom it may concern:

Be it known that I, MARTIN R. CROSSMAN, citizen of the United States, residing at Boston, in the county of Suffolk and Com monwealth of Massachusetts, have invented certain new and useful Improvements in Bubble Blowers, of which the following is such a full, clear, and exact descriptionas will enable others versed in the art to which it appertains to make and use the same.

My invention .relates to and has for its objects:

1. To provide a device for the blowing from a solution (ordinarily of soap and water) of one bubble inside an outer bubble.

2. To provide a means, in connection with a bubble solution, of controlling the exhaust of transient air in a blow pipe, so as to first direct it through a side orifice to the outer circumference of the bubble blowing base functioning there to form a large bubble on said outer circumference, and thereafter by continuous blowing through a central orifice of the blow pipe positioned within said outer circumference, so as to form a bubble on said central orifice and within said outer bubble,

3. To provide a convenient and inexpensive knock down construction which exerts a firm friction hold on the blow pipe when assembled in said device, and to provide the other apparent advantages and results disclosed by the following specification,

I accomplish the objects of my invention as shown in the accompanying drawing, which forms a part of this specification and in which Figure 1 is a front view of my device; Figure 2 is a side view thereof; Figure 3 shows the detail of my blow pipe unit; Figure 4 shows a sectional view on the line wm in Figure 1, of bowl shaped element on the circumference of which is formed an outer bubble from the bubble solution used; Figure 5 shows a perspective view of the bubble blower showing the hubbles in position thereon, prefectly formed one within another.

Referring again to Figures 1 and 2, A shows the bowl shaped element in position on the blow pipe unit B. The mouth piece C, preferably of rubber or wood is positioned at the end of the blow pipe. D shows an aperture in the bowl shaped element A, through which aperture D the blow bubble blowers I 4,1923. Serial No. 660,734.

pipe B passes and is firmly held in friction grip by the bracing unit E. v

In Figure 3, F' shows the side opening in the blow pipe B, through which passes a major portion of the transient air in the pipe B, directing the same to the outer circumference G of the bubble forming base. The blow pipe B is best positioned to extend beyond the circumference G as shown in Figuresl, 2, and 5. I

It will be understood that the bubbles shown in Figure 5 are formed by first inserting the end of the blower oppositethe mouth piece C in a bubble solution, and then blowing into the pipe B through the mouth piece As the transient air passes through the pipe B, the resistance being less within the outer circumference G than at the central orifice H, a major portion of the transient air exhausts through the opening F, and forms a bubble attached to and extending from the circumference G. As the resistance formed by the bubble surface increases, a minor portion of the transient air then passes through the orifice H, forming on the circumference thereof a second and smaller bubble, the same being formed within the larger and outer bubble. When properly sized by continued blowing the bubbles one within the other are, by a slight movement of the blower, dislodged from the device and sail through the air as bubbles only can, all to the interest and amazement of onlookers.

My device may be made from soft or hard rubber, celluloid or any suitable material, but I find sheet aluminium particularly appropriate and of non-rusting qualities. The bracing unit E is very effective when made from cork. If desired a holding pin may be driven at I, in which event the pipe B is permanently fixed in position.

Having thus described my invention I claim as new and desire to secure by Letters Patent of the United States of America;

1. A bubble blower comprising a blow pipe presenting an unobstructed longitudinal airassage from the mouth piece to the bubbleorming end and having one side wall thereof pierced adjacent the said bubble-forming end with a lateral opening through which is adapted to pass a major portion of the transient air in the blow pipe, a disc of cork encircling theblow pipe above the said lateral opening and frictionally engaged with the blow pipe, and a bowl-shaped element supported upon said disc and depending therefrom with its mouth end positioned below the said lateral opening but spaced inwardly of the bubble forming end of the blow pipe.

2. A bubble blower comprising a blow pipe presenting an unobstructed longitudinal air-passage from the mouth piece to the bubble-forming end and having one side wall pierced adjacent the said bubbledormi-ng end with alateral opening through which is adapted to pass a major portion of the transient air in the blow pipe, a. bowlshaped element encircling said blow pipe above the bubble-forming end: thereof, a cork on the inside of the said bowl-shaped element and closely fitting the inner end thereof, said cork having, a central aperture to permit passage therethrough of the said blow pipe and being frictionally engaged with the said blow pipe at a point above the bubble-forming end' thereof: to position the said bowl-shaped element thereon with its mouth end depending below the; said lateral opening of the blow pipe but operated inwardly of the bubble-forming end of the blow pipe, and a holding pin securing the said bowl-shaped element to the said cork.

3. A bubble blower comprising a blow pipe having a bubble-forming orifice at one end and a lateral opening spaced inwardly of the bubble-forming orifice, and a bubblefor-ming base consisting of an outer bowlshaped element presenting a relatively large bubble-forming orifice and an inner bracing element of cork centrally apertured to fit onto and frictionally engage the said blow pipe for positioning the said bowl-shaped element relative to the bubble-forming end of the blow pipe, said bracing element engaging the blow pipe above the said: lateral opening thereof.

In testimony whereof I aflix my signature in the presence of two witnesses.
