(Cl. l1li- 7) Claims.
This invention relates to a. gun for producing bubbles whereby a plurality of bubbles can be formed by blowing a stream of air through a circular member which is coated with a bubbleforming solution.
p Heretofore, bubble-forming devices have largely consisted of a member comprising a handle member and a ring on one end of the handle member, and this ring portion is dipped into a bubbleforming solution and then either th'e member is waved through the air by being seized by a hand of the operator or, in some instances, the operator blows through the ring to produce bubbles.
f It-is impossible for the operator to direct a concentrated stream of air with accuracy through' vthe center of the ring to produce the bubbles,
and by the gun herein shown and described it is possible to center the annular or ring member with regard to the axis of the stream of air issuing from a nozzle so as to producea plurality of bubbles in a much more eicient manner than h'as heretofore been possible by blowing through the annular member with a stream of air directed by the lips or by waving the bubbleforming device to cause air to pass therethrough. It is an object of this invention to provide an vapparatus having means whereby a quantity of centered in front of and with relation to the longitudinal axis of the nozzle so that when air is emitted from the nozzle, it passes through the annular member coated with a film of the bubbleforming solution to thereby produce a plurality of bubbles without any waving of th'e bubbleforming device as has heretofore been the practice.
It is another object of this invention to provide a bubble-forming gun having a pivoted member adapted in one position to dip into a .container containing a bubble-forming solution and, by pulling a trigger, to raise the bubbleforming member out of the bubble-forming solution and to aline it with' a nozzle together with fmeans for forcing air through the nozzle to produce a plurality of bubbles when air passes through the annular member raised to operating position in front of the nozzle.
It is another object of this invention to provide a bubble-forming gun having means whereby, by the manipulation of a trigger, a bubbleplate removed;
' suitable material.
therethrough which the trigger finger of the 01u--` erator penetrates. Mounted on top of the stock forming member can be lifted from a container containing a bubble-forming solution and disposed in front of a nozzle connected to one end of a cylindrical member with a pipe connected to th'e other end of the cylindrical member, the pipe' and nozzle being of less cross sectional area than the cylindrical `member and an operator can place a suitable tube in his mouth, the tube being connected to the pipe in one end of the cylindrical member and the nozzle being disposed in the other end of the cylindrical member, so that when air is blown by the operator into th'e cylindrical member and the cylindrical member having a greater cross sectional area than the bore of the nozzle member, a very much greater force can be imparted to the air as it passes through the nozzle member than if the nozzle member were on the end of the tube placed in the mouth of the operator, this enlarged chamber Vof the cylindrical member giving'greater air power for producing very much better quality and a greater quantity of bubbles than would otherwise be the case.
Some of the objects of the invention having been stated, other objects willappear as the description proceeds when taken in connection with the accompanying drawings in which: l

Referring morefspecifically to the drawings, the numeral lil indicates the gun stock, which maybe made of wood, plastic, light metal, or any other This 'stock has an opening Il I is a tubular member I2 having a suitable resilient stopper I3 in one end and another stopper I4 in the other end.
In stopper I4 is mounted a smaller tube I5 to which is adapted to be secured a iiexible tube I6, the free end of the tube I6 being adapted to be placed in the mouth oi an operator whereby air 'may be blown into the tube I2. Stopper i3 has a nozzle I'I therein having a restricted passageway therethrough and through which air may issue to form bubbles as will be presently described;
The tubular member I2 is secured to the top of the gun stock I0 by any suitable means such as inverted U-shaped strap members 20 and 2|. Thel inverted U-shaped members 28 and 2l have; setv screws 20a and 2 la in their upper portions whereby they can be driven inwardly to clamp the tubular member I2 in position in. the gun stock Hl.. The outer end of the gun stock Ill has a vertically disposed opening 22 therethrough which coin aides with an enlarged portion 23 of the gun stock. I Il`. Onthe lower side ot enlarged portion 23 there is secured by any suitable means such as nails, or screws 25 a screw-threaded jar lid' 26 to.- which is adapted to be secured a. jar or container 2'Iv for. containing the bubble-forming solu.- tion 2B. This jar lid, 25 has centrally disposed therein, a suitable opening 29.l through which a wand. portion. 3 Iv may pass throughthe opening 22. This wand portion 3'I` is preferably circular. and has an. upwardly extendingshank34 which passes through asuitable slot 35 in a bolt 3B which'penetrates a downturned portion. 3T of avmember. 38 which is pivoted intermediate its ends Vas at. 39. The bolt 36 has anut 4 I threadably secured there.- on whereby the bolt when driven home will clamp the portion 34 in adjusted. position.. It is to be notedy that the downturned portion 3l of member 38 has a horizontally disposed slot. 43 therein .through which the bolt 36v passes so that. the bolt caribe adjusted laterally inthis slot 43 for lateral adustment of the circular portion 3l and its shank 34.
The member 38 which is pivoted intermediate its ends as at. 39',v has pivoted. to its rear end as at 45' one end oi a trigger .member 46 which is pivoted to the gun. stock as at 4.1' and has a. trigger portion 48 whichs adapted to be engaged. by the i'nger 4910i an operator.. i
F'i-votedat oney end to the trigger 48 is a tension spring 'Ily which is pivoted at its other end as. at 5I` to the gun stock. This spring tends to hold the parts normally inthepositon shown in Figurefl and to return. the parts to this position when the apparatus is operated.
In Figures 9, and 11, there is shown a modified form. of the. invention in which there is `provided side plates BII and 6I between which is secured by suitable set screws 52 a handle portion 53 and spacer blocks 64, 65, and 56..
