To all wtom t mag/concern.:

Be it known that I, DANIEL R.. SACMAN,

This invention relates. to the subject of' toys and especially to that torni of toy which may be used in the harmless production of I pistol made in accorilance withy my invennoise.

The objects of the intention are-the pro.-

\. vision of a deviceof this character having thegeneral form and appearance of a pistol and by means of which a rangibleA dia-- phragm canl be ruptured `by gas; pressure* with` anew-satisfactory detonation the provision of a device et this: character whichshall propel the ruptured portion ot the dia-,2

phragm. for a considerable distance with `a fair degree of accuracy; the provision cfa device of this nature whichV can. be reset by a movement of the parts thereof similar to that required in reloading a rearm; the.- provisi'on of means whereby the resettingI movement will advance intoposition a new :'Erangible diaphragm; the provision.- of means whereby the saidf diaphragml maybe clampedY securely in? position'v so as to prevent the leakage oi compression therepast which would diminishl the violence of the detonation; -while further objects and ad.- vantages of the inventionwill become apparent as the description proceeds;`

ln the preferredembodiment, the frame.

of the devi-ce consistsfoff two. sheet metal members, one of which.' is formed after the similitude of the butt or handle ot a pistol, and the other of which ismade to resemble as closely as possible the body and barrel of a pistol. .The latter member contains an aircompresslngg device, a trigger for holdingsaid air compressing. device against opera-v tion untilv it is desired to discharge the pistol, and a` frangible diaphragm adapted tof be ruptured by the operation of saidl device. The two members are Ahinged together in such wise that when the two are forcibly broken the air compressing device will be reset, and means is also provided where` by the resetting of' the air compressing device will advance a paper ribbon so as to present an unbroken portion to the pressure of the air. The pressure cylinder is then clamped against the paper so, as to prevent the lossof compression, after which the pressure of the air will forcibly eject a portion of the paper with considerable velocity and a large amount of noise@ Generallyv spealring my invention may be defined as consisting of the combinations of v vparts recited in theuclaims hereto annexed and illustrated in the drawings accompanying and forming, a part of this application,

wherein; l

Fig, 11 isa perspective view of a portion of the paper strip employed as ammunition aft-er the ejection of the same.

ters? l represents generallythe barrel mem ber` of. the pistol and' 2 the handle; Each-oil these members. is. preferably made from a slnglepiece oi' sheet metal whereby cheapness, lightness, and uniformity may be mostl easily secured?. rlhe top of the` barrel mem-` ber, indicatedat 3, consists of a longitudinal portion .of suoli a sheet defined by bending.

downwardly the lateral portion, thereof as shown at i- 4l toormsides. A longitudinal portion of each of these sides is. then swelled outwardly as shown at 5.-5, partly for the. purpose of simulating a pistol; barrel, and: partly for the purpose of receivingV the operating parts of the device.

For a distance in the rear of `the muz-` Zle end of this member, the lower edges parallel to the top 3, as indicated at 6, in the rear of whichv the sides are prolonged downwardly so as to form substantially V -o the sides lf are terminated substantially andapertured as at 9 sodas to forma trigger l y of the device as shown in F ig. 7.

At its rearward end each of the sides 4-4 is formed with a rearwardly-projecting, downwardly-curving extension 12 the same being provided with an embossed rib 13, merging at its upper end with the swelled portion 5 and at its lower end with the pivot seat 14. This rib serves to give stiness to the extension 12 'as well as to provide means l for locking the butt or handle in firing position. rthe lower and inner edges of these extensions are connected to the sides 8 by means of webs 15 which are preferablyy shaped to abut each other upon the medial line of the device,

rl`he barrel member is held in shape and the interior mechanism of the pistol supported in place by means of a pair of transverse plates 118 and 19, the plate 18 being disposed at a distance in the rear of the muzzle end of the barrel member, and the plate 19 at the very rear or butt end of the barrel member. Each of these plates is shaped to conform to the shape of the barrel member at the point of its attachment thereto and is provided with studs 18a and 19a respectively whereby it is secured in place. At the butt end of the barrel member the portion 3 is preferably folded downwardly over the surface of the plate 19 as shown at 20, the sides 4-4 being' extended rearwardly a short distance beyond the plate 19 as shown at 21, to receive the forward end of the butt or handle member. The portion 3 is also extended forwardly atthe muzzle end of the barrel member, and rolled downwardly to form a hinge 24 to which is pivoted a plate 25 which forms the muzzle of the pistol and is formed with an aperture 26 in alinement with the swelled portion 5. This plate is also preferably embossed outwardly circularly around this aperture as at 27, which bothimproves the appearance of the device and forms a seat for the reception of a gasket 28, the purpose of which will be described later. The portion o-f the plate 25 opposite to its hinge is prolonged into an extension 30 which is formed to follow the contour of the sides 4 in Fig. 2 and to fall within the same. Near its rearward end this extension is formed with a pair of inwardly projecting parallel arms 31 31 the ends of which are provided with rounded projections 32-32, the sides ofthe cheeks 7 7 bemisses.

ing also divided with complementary sockets 33 33 adapted to yieldingly retain the same. ln the angle between the edge 6 and the cheeks 7 ll have illustrated -the metal sides as formed with notches 34 adapted for the reception of ears 35 carried by the extension 30 whereby the plate 25 may be securely held against forward movement, although obviously this feature could be omitted without invention if deemed unnecessary. rlhe rear end of the extension 30 is formed with a notch 36 for the reception of a tool by meansof which it may be pried open to load the chamber.

Mounted within the casing between the plates 18 and 25, and extending at ,its sides into the outwardly swelled portions 5 5, is a cylinder 40. The length of this cylinder is slightly less than 4the distance between these plates andl it is preferably supported with sufficient 'looseness to permit a certain amount of endwise movement. In this embodiment it is further supported and guided on its upper side by a Hat plate 41 traversing the casing and on its lower side by a pair of spaced rods 42-42 secured in the sides 4 4. The complete withdrawal of the cylinder canl be prevented by forming it with a tongue 43 adapted to engage one of these rods. f The plate 18 is formed with an aperture 44 coaxial with the cylinder 40 and slidably receiving a hollow piston rod 45, the forward end of which is provided with a piston 46 of the usual or any -convenient type closely fitting the cylinder. ln its preferred form this piston comprises a 'cup shaped flexible member closely fitting in the cylinder and having its sides stifened and j pressed outwardly against the cylinder wall by means of an expanding spring 46a whereby its friction is increased. The rear end of this piston is provided with a collar 47 which provides a` seat for the spiral spring 48 whereby the piston is advanced and also a point of engagement for the trigger hereinafter described, as well as limiting the forward movement of the piston as shown in Fig. 2. rlhe opposite end of the spring 48 is seated against the face of the plate 19.

The butt or handle member of the pistol is also preferably formed from a singlepiece of sheet metal bent to proper form, the upper side thereof being unbroken as indicated at 50, and the inner sideand end thereof being formed bythe inturned 'flanges 51,: the edges of which abut each other upon the v medial line of the device. The-sides 52 of the handle are preferably embossed to simulate the usual revolver handle and are se'- cured together by rivets 53. rlhe upper and forward end of this handle is lmade to lit within and conform to the shape of the rear end of the sides 4 and projections 12 and is pivoted to such projections about a rivet 54 inra-eee secured in the pivot seats 14. Spring tongues are also preferably formed in the sides 52 and provided with rounded bosses 56 adapted to engage yieldingly in the grooves 13 so as to maintain the handle in firing position. One of the flanges 51 may also, if desired, be formed with a tongue 57 for the attachment of a ring 58.

Fivoted upon a rivet 60 carried by the upper and forward end of the handle member is a resetting or cocking link 61, which projects through a slot 62 formed in the plate 19 within the circle defined by the spring 48, and has its forward end received in the hollow piston rod 45. The forward @mi of this uni? is provided with a. head 63 adapted to slide within this rod, and the rear end of the rod is formed with an internal shoulder 64 whereby the relative movement of the rod and link is limited. The length of the link is such that when the parts are in the position illustrated in Fig. 2 the head 63 is spaced slightly from the shoulder 64, so that as soon as the pistol is broken the piston rod will be retracted as shown in Fig. 3. Fivoted upon a-rivet 65 secured in the sides 8 8 is a bell-crank leverfhaving a horizontal arm 66 and a vertical arm 67, the former being provided with an upwardly projecting hook 68 adapted to engage the collar 47 when the piston is re-l tracted, and the latter projecting into the aperture 9 to form a trigger whereby the piston may be released. A leaf spring 69 presses against the rear side ofthe arm 67 sons to force the hook 68 into engaging positiomthe upward movement of this hook being limited by a rivet 70 secured in the sides 4 4. rihe amount of lost motion between the piston and the resetting link is slightly greater than the amount of travel of the piston so that when the handle member is returned to firing position the head 63 will travel forwardly along the piston rod to a point short of the piston head, thus leaving the piston and piston rod free to advance under the influence of the spring 48 when released by the pressing of the trigger.

The ammunition consists of a ribbon of paper or like material coiled in a roll 76 received in the space dehned by the arms 31-31. The end of this ribbon is brought forwardly through aslot 77 formed in the plate 18, around the end of the cylinder 40, across the face of the gasket 28, around the curved lip .7 8 of the plate 41, and through an aperture 79 formed in the top 3 at the rear .of the plate 18. The means for feeding this ribbon forwardly so as to reload the pistol will now be described.

By referring to Figs. 2, 3 and 5 it will be seen that the portion 3 and the sides 4--4 of the casing together with the plate 41 define a parallel walled prismatic chamber,

and in this chamber l mount a slidable, tl-

shaped feeder 80 withv the edges of its walls resting upon the plate 41. Formed in the side walls of this feeder are inclined slots 81 receiving a pin 82 carried by an elongated feeding plate 83, the forward end of which is upturned as at 84 and sharpened and serrated (see Figs. 2 and 5) to form paper engaging teeth. The paper ribbon is passed between the base of the feeder and the teeth 84 as shown in Figs. 2 and 3. The plate 83 passes through a slot 85 in the plate 18 and has its rearmost end upturned as at 86, this upturned end being formed with an aperture 87 (see Fig. 6).

Fivoted upon a rivet 88 carried by the handle member is a second link 89 which projects through a slot 90 in the plate 19 and through the aperture 87, the forward end of this link being bent downwardly at 91 through an elongated slot 92 formed in the plate 83. rlhe extremity of the portion 91 is preferably deflected laterally as indicated at 92a so as to interlock with the plate 83. This construction provides a lost-md tion connection between the link 89 and the feeding plate 83, necessitated by the fact that the travel of the feeder 8O is much smaller than that of the link 89.

Ilhe operation of the device is as follows: rlhe plate 25 and its extension are swung forwardly and the end of a roll of paper ribbon inserted over the lip 7 8, between the feeding teeth 84 and the feeder 8O and through the aperture 79.. rlhis ribbon is then unrolled so as to traverse the end of the cylinder 40 and lie in the slot 77, the

roll 76 being positioned between the arms 31, after which the plate and its extension are returned to their position, whereupon the parts will occupy the positions illustrated in Fig. 2. lhe members of the pistol are then broken about the pivot 54 so as to assume the position shown in Fig. 3, the piston being retracted against the tension of the sprmg 48 past the hook 68 as already described. During the first part of this retractive movement the friction between the piston 46 and the cylinder 40 slides the cylinder' rearwardly against the plate 18 so as to free the paper strip. At the same time the link 89 moves freely along the slot 92 leaving the feeder plate 83 unmoved. Prior tothe termination of the breaking movement, however, the link 89 reaches the end of this slot and draws the plate 83 rearwardly, whereupon the inclination of the slots 81 causes the feeding tooth 84 to be pressed upwardly against the paper ribbon which is thus caught against the base of the feeder. rlhe continuation of the cooking movement causes the ribbon to be advanced, thus reeling 0H more paper from the roll and protruding the end of the strip through the aperture 79.

'llhe handle is now returned to firing position,

- strip, and after the feeder has reached the limit of its movement the link 89 slides along the slot 92 until-the handle is locked to the barrel by the fingers 55. rlhe short forward movement of the piston, prior to its engagement by the hook 68, also frictionally advances the cylinder i() so as to press the mouth thereof against the inner face of the paper strip and wedge the same against the gasket 28. lf the trigger 67 be now pressed so as to release the piston, the air in the cylinder will be comy pressed until the paper ribbon will no longer support the strain, when the portion thereof defined by the aperture 26 will be ruptured with a loud report and thrown for a considerable distance. The portion 3 of the barrel is preferably embossed as at 95 to form a sight. rlhe strip of paper is torn od as it is protruded through the aperture 79 so that the view of this sight is not impeded.

It will be understood that the use of the particular kind of ammunition described is not essentialto my invention, as l may in some cases employ a ribbon having portions of diderent thickness and weight so that the inertia of the projectile may be increased. Likewise l do not confine myself to the employment of a plate 25 of small thickness, but esteem my claims to cover a condition in which a closure member of considerable length of bore is employed. ln general, therefore, while l have necessarily described' my invention in -detail l do not propose to limit myself to such details except as the Asame may' be specifically recited in the claims hereto annexed or may be rendered necessary by the prior state of the art.
