Patented Aug. 15, 1950 BUBBLE GUN AND HQLSTER THEREFOR Robert Lorenz, Denver, 0010;

Application February '7, 1946, Serial No. 645,392

This invention relates to improvement in toys and particularly to toys for bubble blowing.

It is an object of the invention to provide a toy which can be readily held in and operated by one hand for the purpose of blowin bubbles.

A further object is to provide in combination with such a'bubble blower, a holder for such blower'adapted to supply the blower with bubble fluid. p

A further object is to adapt an air gun to use as a bubble blowing gun.

A further object is to provide an attachment for, or addition to, an air gun whereby such gun may be used for blowing bubbles.

Other objects will hereinafter appear.

With such objects in view, all of which will hereinafter be more fully disclosed, the invention comprises certain novel constructions, combinations and arrangements of parts as will now be fully described and as will be defined in the appended claims and as illustrated in the accompanying drawing in which Figure 1 is a top or plan view of the bubble gun.

Figure 2 is a vertical, central section of the same showing the piston and associated parts in rearward position ready for bubble blowing action.

Figure 3 is a fragmentary view on same lines as Figure 2 but showing the piston and associated parts in foremost position after firing, and

Figure 4 is a front end elevation of the bubble gun.

Figure 5 is an elevation of my improved holster with bubble fluid supply and illustrating the gun, partly in broken lines, in position in the holster.

The gun is preferably formed, for convenience and efficiency, in conventional pistol shape with a handle 5 carrying an air cylinder 6, simulating, in both form and position, the cartridge cylinder of a revolver, from which cylinder tube 1 projects forwardly, simulating, in form and position, the barrel of a revolver. The front end of tube I is closed, as at 8 but the closure is provided with a small central orifice 9 adapted to emit a stream or jet of air when the device is operated in a manner later described.

The bubble assembly is mounted on the front end of tube 1 and comprises a ring Ill carried between the front ends of bars Hv whose rear ends are mounted on the front end of tube 1, by soldering or other suitable means, as indicated at l2. It will be understood that the center of ring I!) and orifice 9 should be aligned with the cenrz Claims. (01. 46-8) tral longitudinal axis of tube 1, or parallel-theref' Cylinder 6 is provided with a piston'lS whose the rear of the cylinder as shown at Figure :2.

Trigger I5 is pivotally mounted in the forward part of handle 5 as at H, the lower portion 18" forming a finger piece and the upper-portion l9" being provided with an arcuate slot 20 adapted to engage pin Mb carried by rod M, whereby the retraction of finger piece I8 will move rod 14" and piston 13 forward to the position shownat The rear end of rod l' l'is preferably Figure 3. slidably mounted in a guide 2| carried byhandle 5. 1

Front and

rear sights

22 and 23 are shown only; for symmetry and ornamentation and form'no part of the invention. The usual trigger guard 1 24 is shown for like purpose and is no partof the invention.

In operation the elements are in normal position as shown at Figure 2, the cylinder 6 being filled with air in front of piston l3. Ringjlll is dipped in some suitable bubble forming solution which forms a film across the ring. Finger piece i8 is drawn back forcing piston l3 forward and forcing a jet of air through and forwardly from orifice 9, which jet will contact the center of the film across ring l0 bending the film outwardly;

and forming a bubble in a manner well under.-

stood. The spacing of the ring H] with respect to the.- point of air emission from the orifice 9 controls the velocity at which the air streamstrikes the film of bubble forming liquid and in order to accomplish the results, this spacing.

must be within definite limits. The-spacing of the film of liquid with relation to the point of air emission is such that the velocity of the air stream striking the film is sufiicientto form and.

project a bubble or bubbles forwardly fromsaid film but yet the velocity is not sufiicient to break entirely through the film without the formation of a bubble. In addition to permitting a control. of the velocity of the air stream at the timethat said stream strikes the film', the air space be tween said film and the orifice 9 functions to nullify any suction effect which might bet-pro;

duced upon the back stroke of the piston, which suction might break the film and 'displace it,

In other words,upon thebackstroke of "the piston air may be drawn into the from the ring.

3 cylinder through the orifice with said air entering the orifice behind the film and without creating any suction against the rear surface of said film. With the right solution and practice in operation of this device a number of bubbles may be blown from the ring successively during a single complete forward stroke of piston 13.

While the bubble gun may be used wherever there is a supply of bubble liquid in which to dip the ring H1, its preferreduse is; as, a part; of; theg complete toy comprising the gun and a liquidcarrying holster now to be described.

A holster 25 is providgd, preferably provided with a belt 26 for attaching the holster to the; person, the holster and gun being so relatively formed and proportioned that the gun will rest in the holster as indicated at 2'1? and 28a The; bottom end of the holster terminates in a liquid, container 29 suitably secured to the holster preferably threadedly as conventionally indicated at 30;,the; container beingso proportioned and posi tioned that ring III of the gun will, when the. gum isseated: in theholstel, be suspended in. the liquid; 29w. near the bottom of the container so: asrtbebesubmergedthereinwhenever there is any substantial quantity of liquid in. the container without touching; during insertion into, with drawal from, orrest within the container; either the bottom, or the walls of the container.

'iihus; whenever-there isiany substantial. quantity ofi'bubbleliquid in the container-thegunmay carried: in the holster and at any time withdrawn for use inxbl'owingbubbles, afilm of bubble liquid: always adhering to and" covering ring IO whenwithdrawn, thus rendering the gun ready ion bubbleblowing, immediately upon withdrawal incur the holster.
