.6 Claims. (Cl. 124-1) The invention relates to toy guns,` and par-A ticularly to toy guns adapted to expela concentrated charge of air or gas. f

It is among lthe objects of the invention to produce a new and improved toy gun which is practical and harmless but at the same time capableA of being directed toward and shot at a target with a considerable degree of accuracy.

Another object is to provide a new and im, proved toy gun which is capable of shooting any number of charges at a target without the necessity of replenishing the gun with ammunition.

Still another object is to provide a new and improved toy gun which issafe from.A all stand-g' points, which is positive acting and which incorporatesa relatively minimum numbervof parts,

Figure 14 is a fragmentary, sectional.v exploded view ofthe parts comprising the fastening means do damage when carelessly used evenwhenthe object might be as soft, for example, as thecom- Inonly -used cork in a pop gun.' In some cases;

of rugged construction, serving to produce a toy that will give lasting pleasure for an extended period of time. n

With these and other objects in view, the invention consists in the construction, arrangement and combinaticn'of the various parts of the device whereby the 'objects contemplated are attained, as hereinafter more fully set forth, pointed out in the claims and illustrated in the vaccom-- panying drawings, in which:

Figure 11-is a fragmentary, longitudinal, sec? tional view showing in detail a means for fastening the diaphragm. i i

Figure 12 is -a fragmentary, sectional, exploded viewshowing the parts which comprise the fastening means of Figure 11. Y Y Figure 13 is a fragmentary,` longitudinal, sectionalview of `a modified type ofY fastening means for the diaphragm." f

Q11 the' as in the `familiar pop gun, the cork istied to 'ai Y string so that it cannot be s'hotftoo far. Confining means such as this are disadvantageousl-in that the gun has no accuracy andr cannotlbe directed satisfactorily atatarget. 1 l

The ring of the invention can bev likened to a smoke ring, and it has been found that if the air is expanded rapidly enough and is vofsufii-y cient volume in relation to the exit opening. a

' ring will travel outwardly at a sufficient velocity to carry the ring a necessary distance to produce satisfactory results. In the invention herein described the'object l projected from the gun is nothingfmore-than a compact vring of compressed air Aand can dol no more damage than a strong gust-,ofv wind. IilThe ringof air, however, lis suiciently compact :sof that it is adapted to travel considerable diss-a tances and isv capable of impinging .with-'consid-A erable force upon aproperly ydesigned targets-By reason of the fact ythat air finds 'its `vl'layin-tor the gun through the normal openings therlis no necessity for recharging the gun at any time since air as ammunition is alwayspresent.-A

.'InL/one embodiment chosen for the purpose .of illustration there is shown asin Figure*i 11a toyl gun comprising a barrel I0 of relatively: large diameter having a 'pistol grip yI I, a'fbree'chend I2 substantially closed except for a 'central aper-z ture I3 and a muzzle end Ill.

In a modied form of the device illustrated in Figure 3 a barrel 40 of the usual dimensions has been provided having a customary closed breech end 4I and a ange 42 at the muzzle end. A diaphragm 43 is stretched taut within the barrel intermediate the ends and held in place by a ring 44 and screws 45. A pistol grip 46 and trigger guard 41 are likewise provided.

In this instance, the means for actuating the diaphragmkis' incorporated in afhammer 48 which isf-mounted upon-a- 1everarmf-4S'pivoted"by means of a pin 50 extending in a transverse direction wi-thin the barrel. The hammer is held in position by a coiled compression spring 5| which is mounted upon a bracket 52 likewise within the rbarrel. Forlactuating the hammer there is provided a trigger .53 pivotally supported upon a pin 54 at the forward portion of the grip beneath the barrel. A plurality of iinger grips 55 extend radially outwardly from-,the center of the trigger andjareadapted tog rotatezwithin thegpistolfgrip and'uthrough ,a1slot,56 inthe bottom ofthe fbarrel.4

the lower edge of the aperture 68 in the same lmanner as described in connection with Figure 1.

The gun4 in the vembodiment illustrated in Figure 4 isreleased by the same trigger mechanism as described in connectionwith Figure'l and incorporates a trigger grip 'I3 and an angular llifting lever I4 pivoted at the point 15.

I In this latter instance, there is provided a large coiled spring 'I6 which is fastened to the inside surface of the fiange |52 and to the adjacent surface of the piston 63. When the rod 56 is drawn yrearwardly to a cocked position the spring is `ring in the manner previously described.

To Yvary the style yof the gun it may beprovided with a rie stock as shown in Figure 5, and the barrel of any one of the formsmay be extended as indicated at 8| so as to fit over the rifle stockwithout altering the mechanical operation of the gun itself. If preferred, the rod may terminate in'a knob 82 extending at right angles to the axis of` the rod so as to give the effect of the characteristic loading bolt used on real guns. In this instance, the knob is at the end of a right angular lever 83 lextending upwardly through a slot 84 at they top of the barrel. A wall 85 `may be used to entirely close the breech. In other respects the mechanical arrangement of .Figure is similar to that of Figure 4.

By yway of example, there is shown in Figure .6

the type described. It may comprise a frame 90 supported in an erect position by means of Suspendedfrom the upper horizontal portion of the frame may be a seriesof paper or other streamers 52 colored or marked so as to indicate a bulls-eye $3.y If the streamers are permitted to hang freely. they will shake surdciently to indicate a hit when the compressed ring of air discharged from the gun impinges upon the target. n Y

It will be apparent from the foregoing description that there has been provided a toy gun which is particularly easy to operate and which by reason of shooting nothing other than the compressed ring of air can be operated freely about the house without fear of creating any undue damage.

In a particular form of the device which has been designed to suggest some of the so-called modern weapons there is shown in Figures 7, v8, 9 and 10a voretex gun having substantiallyv the same principles previously described.

The gun comprises a body |00 having a streamlined breech end |0I and a muzzle end |02. The muzzle end has an enlarged cylindrical portion |03 tapered abruptly along an' inwardly curved line |04 to a muzzle orice |05 which has a-diameter substantially smaller than the diameter of the cylindrical portion |53. A flexible, resilient diaphragm |05 is mounted at the muzzle end of the cylindrical portion and in the course of operation is adapted to be moved between positions |06 and |06". n

As is customary, the gun is provided with a pistol grip |01, a trigger guard |08, a trigger |09 and a cooking bar or lever IIO, the cooking lever being pivoted at the point I II to the rear face of the cylindrical portion |03.

In order to operate the gun, means must be provided for pulling the diaphragm rearwardly to the position |06 and suddenly releasing it so "6 rthat due to its inherent resilience it snaps quickly forward to theposition |06. v i

In this embodiment the operating mechanism consists of a bolt II5 which slides freely within a bushing I6 located in the body axially with respect to the center of the diaphragm. l The bushing is provided with along slot I I'I which is adapted to accommodate a bracket I I8 connected by means of `a link I I9 toa pivot point |20 on the cooking bar. tion that the center line betweenv the bracket ||8 and the pivot point I I is over center with regard to the pivot point |20 when the cooking bar isin closed position. By virtue of this arrangement the cooking bar is snapped and held in a cooking position until the kdiaphragm can be released.

At the inner endr of the bolt I I5 is a forked portion |2I having two tines between which is pivotally mounted a hooked element |22. The hooked element has a base |23 cut on the bias so as to abut against a bias shoulder |24 at the end of the bolt. A leaf spring |25 attached tothe underside of the bolt acts against the hooked element tending always to raise it tothe position shown in Figure 7 above which the hooked element is prevented from moving by the bias shoulder I2Il.

The trigger |05, pivoted at the point |25, has a forwardly extending portion |21 which is adapted to slide over a pin |28 which is attached by means of an extension |25 to the forward end of the hooked element. A U-shaped eyelet |30 is attached by means of washers I3I and |32 to the center of the diaphragm. The diaphragm Amay be stretched and held in placeby a ring |33 which bears outwardly against the inside wall of th cylindrical portion |03.

, In operation the parts of the gun will initially have the positions shown in Figure 7. To rst cock the gun it is necessary to lift the cooking bar IIIl to the dotted position IIO. This movement draws the bolt II5 forwardly until the hooked element occupies the position |22. In this position the end of the hooked element springs downwardly upon contacting the U-shaped eyelet |30 and is then snappedupwardly by means of the leaf spring |25. vAfter the bolt has thus engaged the diaphragm, the cocking bar is pressed downwardly toits original position, and this movement forces the bolt II5 rearwardly to a cocked position wherein itis locked by the over center relationship of the link IIB. During this movement the bracketv IIS slides along the slot Ill. Meanwhile, a spring f ,|34 or other appropriate means will hold the trigger up. Y

rWhen the trigger is pulled, the forward portion |21 thereof moves downwardly to the dotted position shown in Figure 1. This pulls the hooked element downwardly and releases the eyelet and the diaphragm so that the diaphragm snaps abruptly forward, thus expelling air through the muzzle orifice.

It is important to note that the tines I2! extend sufficiently far vforward so that the eyelet will rest upon the tines in an axial position while the hooked element is being released, thus maintaining the diaphragm in a centered balanced po.- sition so that it will drive forward in a straight,
