2"Claims. (Cl.40-126) Thisinventionrelates to'garr apparatusfor forming and projecting bubbles andhas for its principal object the provision of aconstruction' of this character which will be highly efficient in use and economical in manufacture.

An important object of theinvention is the provision of an apparatusespecially adapted for use" in places of resultingin the floating of the bubbles slowly and gently in the air for a considerable length of time before bursting, thus adding; totheattraetionand entertainment of the observers.

Still another object" of 'thei'nventi'on is the provision of a bubble producing and projecting apparatus which may be used to provide an attractive and aesthetic background for acts of entertainment or exhibitions, as well as an advertising medium.

Yet another object of the invention is the provision of a bubble producing and projecting apparatus of such construction as to be compact and portable.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

Fig. 1 is a perspective view of the invention;

Fig. 2 is a sectional detail view taken substantially on line 2-2 of Fig. 3;

Fig. 3 is a sectional detail view taken substantially on line 33 of Fig. 2;

Fig. 4 is a rear elevational view of the apparatus shown in Fig. 1, illustrating the back wall thereof in open position;

Fig. 5 is a fragmentary sectional detail view taken substantially on line 55 of Fig. 2;

Fig. 6 is a perspective view of a hollow drum embodied in the invention.

In the drawings I have illustrated the preferred form of construction of my invention by which the several objects thereof are accomplished. In this connection, my invention includes a cabinet 10 mounted upon suitable casters 11 to facilitate moving the cabinet 10 about. The cabinet 10 includes side walls 12 each having a port hole 13 formed therein.

The back wall 14 of the cabinet is hinged as at 15 to an adjacent side wall 12. This back wall has a port hole 16 formed therein (Fig. 4).

ICC

The top wall of the. cabinet comprises a horizontal portion 17 and aninclined portion 18. Theinclined portion 18 hasa pair of rectangularly shaped openings 19 formed therein. Hinged to the topwall as at 20 is a door 21 which normally closes the openings 19" when the apparatus is not in operation, there being provided a suitable lock 22 for locking the door in, closed position. The back Wall 14 is normally locked in closed position, and for that purpose there is provided a suitable lock 23.

The front wall 24 of the cabinet is inset as best shown in Figs. land 3; Beneath the top wall 17 is a shelf 25. On the shelf 25 in close proximity to the openings '19 is a removable pan 26 which is adapted to contain a bubble making solution of a well-known formula.

Operating within this pan 26 is a pair of drums 27. These drums are hollow in construction and each includes a Wall 28* and a ring 29,1 the ring 29 being connected to and spaced from the wall 28' by crossbars 30 (Fig. 6). These drumsZT-are each supported by a shaft 31, the shaft supporting the-drum in a position so that alower portion of each drum willrotate through the bubble making solution contained in the pan 26. The shafts 31 are eachrotatedby a motor 32 (Figs. 2 and 4). These motors 32 are designed to rotate the drums 27 at that speed of rotation which will result in a film ofthe bubble solution enveloping the drums.

Projectinginto each of the drums through the ring 29 is a nozzle 33, the orifice of which is formed to provide an elongated slot 34 directed in a direction toward the periphery of the drums. These nozzles 33 communicate with an elbow-shaped conduit 34' which in turn communicates with a blower fan 35 suspended from beneath the shelf 25withi'n the cabinet 10 and operated by a motor 36 (Fig. 4). The speed of this motor is regulated by a suitable and conventional rheostat 37\(Figs. 3 and 4). Byadjusti n-g the rheostat 37, the motor 36 will be caused to rotate the blower fan at a proper speed sufficient to force air through the nozzles 33 in the direction of the periphery of the drums 27 to form and detach therefrom bubbles successively from the film of the bubble solution enveloping the drums 27.

In order to lengthen the suspension of the bubbles in the air and to retard their downward movement, means is provided for moving the air within the entertainment or exhibition area where the bubbles are being projected. In the present instance, I prefer to accomplish this object by providing in the front wall 24 an open grille 38. This grille 38 comprises a plurality of louvers 39 (Figs. 1 and 3) which are rotatably supported upon rods 40 and held in an adjusted position by spring fingers 41. By adjusting these louvers 39 the direction of air emanating from a blower fan 42 may be controlled. This blower fan 42 is arranged within the cabinet 10 opposite the air ports 13.

The electric motors are connected in a suitable power circuit (not shown), in which circuit there is arranged a control switch 43.

When in use, the motors 32 will rotate the drums 27 with their lower portions passing through the bubble solution contained in the pan 26. The blower fan 35 will blow air through the orifices 34 of the nozzles 33 to form the bubble frornthe film of bubble solution enveloping the drums 27. As the bubble is formed and released from each of the drums 27 under air pressure from the nozzles 33, the bubbles will float upwardly. Their suspension in the air and direction of travel will be controlled by the air fro-m the blower fan 42, which is operated by a suitable motor 44 (Fig. 4). a

The amount of air passing from the nozzles 33 is con trolled by the rheostat 37. The blower fan 35 may be caused to rotate at a speed sufiicient to form the bubble from the film of solution on the drum 27 and cause the detachment of such bubble from the rotating drum.

To control the direction of movement of the bubbles after they are released from the rotating drums 27, the louvers 39 may be adjusted to such position as is best suited for the purpose.

In order to drain the solution from the pan 26 after the apparatus has been operated, there is provided a suitable drain hose 45. This hose 45, when the apparatus is in operation, is maintained in the position shown in Fig. 3, with the upper end 46 thereof supported above the level of the solution in the pan 26 and held in such position by a spring clip 47.

My improved bubble formingand projecting apparatus may be used in many places for the forming and blowing of bubbles about a given area. It has been particularly designed and constructed for use at a place of entertainment or exhibition where it is desired to produce the efiect of floating or drifting bubbles. The apparatus is compact in construction and by reason of its being mounted on casters may be easily and conveniently moved about.

While I have emphasized that my improved bubble forming and projecting machine is especially designed for use in places of entertainment or exhibition, such as theaters, dance halls, skating rinks and the like, it is obvious that such apparatus may be used for advertising purposes to attract the attention of observers and in any location to provide an aesthetic and attractive background which will hold the attention of observers.

While I have illustrated and described the preferred form of construction for carrying my invention into efiect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:
