PAPER BUBSTING TOY GUN Alfred F. Langos, ChicagoQIlL, assignor to Lang- 'son Manufacturing 00., Chicago, 111., a corporation of Illinois Application July5, 1950, Serial No. 172,052

.1 Claim. (Cl. 46-195) This invention relates to a paper bursting toy. More particularly, the invention relates to a paper bursting toy'of the type whereina strip of feedable paper is automatically fed and sealed over an air pressure developing means having a member movably seated therein for building up sufficient air pressure to-burst thepaper.

. In paper burster toysgenerally, and more-particularly .in paper bursting toys of the types set forth above, considerable trouble'has been experienced in providing a positive acting paper feed for such toy, which would assure automatic feeding of the paper to be burst during each operation of the'toy. Due to the fact that these toys are confined in their size and outside configuration in order to. appeal to children, this trouble has been further amplified. ;-Whi1e an otherwise satisfactory paper feedmechanism is known in the art, it has heretofore been impossible to incorporate such mechanism in certain toy configurations. f It is therefore one object of the presentinvention to provide a paper burstingtoy having an improved paper feed mechanism.

Another object of the invention is to provide an improved automatic paper feed mechanism adaptable for use in a paper bursting toy having limited space available for such mechanism.

a triggeractuated toy pistol paper burster, having a paper feed operated directly off of .the

pivoted trigger which adequately engages and feeds the paper on the cooking stroke, but on the return movement of the trigger ismaintained out of engagement with the paper. I

A feature of the invention is the provision in a paper burster toypistol of a paper. feed operating directly off of a pivoted trigger on the toy, which moves in an arcuate feeding path'during the cocking'stroke of the trigger, but which is guided out of the feed path and prevented from jamming or otherwise affecting the paper on the return movement of the trigger. Y 'Another feature of the invention is the provision of a paper feed mechanism includingan arcuately movable paper feed means tensioned by guide means during a portion of its feeding "stroke'for positively engaging and feeding paper, and maintained out of engagement by guide means on its return movement to prevent jaming detailed description taken in conjunction with the accompanying drawings, wherein:

a Fig. 1 is a sectional View of a paper bursting, I

toy having a desired configuration, andshowing the improved paper feed mechanism in a first operative position thereof;

Fig. 2 is a sectional view of the gun shown in Fig. 1, showing the improved paper feedmech- 'anism in a second operative position thereof;

Fig. 3 is a perspective view of a paper feed pawl and connecting link therefor, the'construction of which comprises a part of the present invention; and

Fig. 4 is a blown up, fragmentary view of the improved paper feed mechanism.-

In practicing the invention, a paper bursting toy having feedable paper adapted to be intermittently fed to, and burst by a spring actuated paper bursting means, is provided. The paper bursting means is operatively connected to the toy actuating means which includes a trigger, for cocking and releasing the paper bursting 1 means to cause the same to burst the paper.

In order to feedpap er to the paper bursting means, a paper feed mechanism is provided which includes an arcuatelymovable paper feed means operatively connected with the trigger for concurrent movement therewith. The arcuately movable paper feed means is tensioned by a guide means in the toy, and engages and feeds the paper during a portion of its arcuate travel, upon the trigger being cocked, but is prevented from engagingthe paper on its return movement by reason of a guide means engageable by a portion of the paper feed means during the re:- turn movement.

Referring now to the drawings more partic ularly, Fig. .1 shows a paper bursting toy of the type disclosed in application Serial No. 114,113, filed September 6, 1949, of Otto E..Langos, inventor, and comprising a housing H having a gun configuration. Carried in the housing ll is in cylinder I & during the compression or bursting strokeof piston 16.

Piston It and piston rod I! are the action of coil spring l8, by an actuating means including a toggle lever assembly comprising a pair of double levers 22 and 23, a coil tension spring 24, and a key member 26 driven by a trigger 2T pivoted on housing H by means of cooked against 7 rivet 28. The actuating means detachably engages piston rod I! to cook the same, and is disengaged therefrom at the end of the cocking stroke, to allow piston Hi to be driven rearwardly by coil spring l8 for bursting paper I2. For the purpose of feeding fresh portions of paper to aperture I9 during each cocking-strokeof the toy, an improved paper feedmechanism comprising an arcuately movable paper feed means operatively connected to trigger 21, is provided.

The paper feed means includes a lever extension 29 formed on trigger 21 to which a feed pawl 3| is operatively connected. As isbestfifi n in Fig. 4, feed pawl 3| normally .engagles paper,;l-2'

to press the same against paper guideway 13, and is connected by a resilient link 32 to lever extension 29 on trigger 2'1. Link '32 is piv'otally mounted on a pin 33 which protrudes irom a recessed portion 34 formed in lever extension 29. Recessed portion .34 forms a guide edge or stop 36 on extension 23 which cooperates with link 32 to force feed pawl 35 upwardly upontrigger 2'? being moved rearwardly on its cocking stroke. In the idle position, feed pawl 3 i is biased downwardly into cooperation with paper,guideway i3, by a bias spring 31 coasting with 11m; 32, and is prevented from dropping out of engagement with paperguideway ,l 3,.by a stop pin 39 protrudi space available for an automatic paper feed in that type of gun,

In operating the gun, trigger 21 is pivoted rearwardly about pivot pin 28, causing a bifurcated, integral extension or lever arm having a roller 52 supported between the arms thereof, to be I pivoted forwardly. Roller. 52.. normally; engages a camsurface 53 formed on the rearward edge ofkey member 25, and upon being forced for- ,wardly, serves to drive key member 26 forwardly.

Mounted on the forward end of key member 26 is toggle. lever assembly 22, 23 comprising a pair of .double levers each of which straddles key member, 26,. and is fulcrumed by a pivot pin 54.

Double leveri2 2 also straddles piston rod l1, and is fulcrumed on housing I I by pivot pin 55. Douing from housing II. On the upward or feeding stroke of feed-pawl 3!, link 32 cooperates with aguide means 39 fixed toliousingil in a manner, hereinafter to be described, such that feed pawl 3! is maintainedin contact with paper l2 during the greater portion of its feeding stroke, and is maintainedout of contact with said paper on the return movement, 2 Referring to Fig. 3, link 32 consists of a flat resilient strip having one end 41 curled to fit about pivotpin 33, and a downwardly extending,

integrahside flange 42 iormed on the remaining end 43 thereof, upon whichv .feed pa wl Si is mounted. S 1 1 bsta ntially opposite flange42, is a rectangular notch 44 formed link 32, and which cooperates with guide means 39 on the feed stroke, in the following manner. Adverting again to Fig, 4, up0n trigger 2l being pulled rearwardly, guide edge or stop 36 forceslink 32 upwardly. Rectangular notch 44 is cut suff ciently deep, and is so positioned on link 32, that link 32 rides over guide means 39, with the side of notch 44 engaging oneportion or surface 46 thereof, thereby maintaining feed pawl 3!, in contact withieedable paper 12. Guid means 39 is soshaped that guiding surface 43 tensions feedpawl 3t against thefeedablepaper, and then towards the end of the feeding stroke, allows the pawl to snapaway from the paper to. the position shown in Fig. 2. Likewise, due to the shape andposition-of g'uide means 39, on the return movement of trigger 2'!, .end 43.01 link 32 engages a second portion or ,guidingsurface-H of guide means39, which .action results in maintainingfeed pawl ,3! out of contact with paper [2 on its return movement; therebypreventing the-feed pawl from pulling paper l2 downwardly and jamming or tearing the same. By reason of its. simple constructionand suitedfor a Western type' gun, due to the small together by a crosspin 58. In the idle position, erossr i hie e upwardly by spr n Z ,..a normally seats in a shoul'der 59 formed in the lower edge of piston rod 11. Upon key member 26 being driven forwardly, this motion is transmitted through the toggle: lever assembly22 and 23 topisto'n rod I1 't'ocock the same.

Simultaneously with the forward movementof I key member 26, pivoted breech 2! is sealably closed over aperture [9, which is formed ina rubber'grommet 6| fitted over the end of cylinder I6, by means of a connecting link-'62 pivotally connected to breech- 2! by a pivot 53. Link 92 has an elongated slot;64formed in its forward end which cooperates with a pin i5 onkeymember 26, to provide a lost motion connection-for breech-2|. Hence, breech-2L is not closed over aperture i4 until after the paperfeedingoperation is completed.

On the forward-endof key member- 26, there is a rounded-shoulder or cam surface-filwhich engages a stationary-pin 58 in housing I I, upon the key member 26 nearing the forward limit'of its travel,- as is illustrated in Fig, 2. :Upon shoulder 6'! strikingpin BB and continuing tomove forwardly, key member 25 is tilted downwardly on its line of secondary movement.- It shouldbe noted that the fulcrumpin 54 that connects double levers 22 and 23, normally bears against a round shoulder 69 formed on. the lower edge of key member 26,- and, asis best shown in Fig. 2, upon-the key member-26 reaching the. forward end of its-travel, pin 54 rides off the shoulder..69 and enters a recess ll adjoining the shoulder 69. This prevents any further-pivoting of the double lever -.23, which is held locked against further angular movement by the combined. action of double lever :22 and keymember 26 so long as the key member is in theeXtreme-forward part of itstravel. Therefore, as the key member .26 is tilted downwardly upon engaging stationary pinJiB, double lever 23 is. pulled downwardly ,to clear thecrosspin 58 from shoulder 59 in-piston rod l1. Piston i3 is then free to move rearwardly under the pressure of coil spring ii! on its paper bursting stroke. Meanwhile, trigger '21, key member 26, feed pawl-3 I, movable breech-2 Land togglelevers 22 and 23,are held intheposition shownin'Fig. 2.

As piston it moves. rearwardly, it builds up air pressure withincylinder Min back of the paper strip 12 which is clamped over aperture I9--in grommet 6| by movable breech 2i. Breech-2l has a centrallydisposed -hole, the outline of which is shown at '13, extending therethrough in registry with the aperture in grommet 6|. Therefore, upon the air pressure withincylinder l4 reach- 5 ing a certain value, the paper strip l2 sealing aperture I9 suddenly bursts with a loud report. Subsequently, trigger 21 is released, allowing all of the parts controlled thereby to assume their normal position shown in Fig. 1, by reason of the action of bias spring 24. Inreturning, crosspin 58 rides along the lower edge of piston rod I1, and eventually seats in shoulder 59. Movable breech 2| is pivoted outwardly by lost motion link 62, and feed pawl 3| is returned to its idle position in the above described manner. From the foregoing description, it is seen that the present invention provides a positive acting paper feed which is simple in construction, and which can be incorporated into a paper bursting toy having limited space available for an automatic paper feed. The invention assures that an unbroken portion of paper is fed to the paper bursting means during each operation of the gun, and prevents tearing or jamming of the paper during the return stroke. Thus, automatic paper feeding is provided, and proper operation of the gun is as sured.

Obviously, other modifications and variations of the invention are possible in the light of the above teachings. It is therefore to be understood that changes may be made therein which are within the full intended scope of the invention as defined by the appended claim.

I claim:

In a paper bursting toy having feedable burstable paper and means adapted to be cocked and released for bursting said paper, the mechanical means for feeding the paper through the gun and for cocking and releasing said paper bursting means to cause the same to burst the paper, said mechanical means including in combination a pivoted trigger adapted for operation in a cocking movement and in a return movement, a paper feed mechanism including an arcuately movable flat resilient arm pivoted at one end to said trigger, having a paper feed member secured thereon at the other end and being concurrently operable with the trigger for engaging and feeding said paper during a portion of the travel of said trigger while in a cooking movement, said resilient arm having a notch portion and a shoulder portion spaced in order respectively from the pivoted end of said arm, and fixed'guide means on said toy spaced relative to the arcuate travel of the arm so that the notch of said arm straddles the fixed guide means and has an edge thereof in engagement with said guide means during a paper feeding operation, with said guide means engaging said shoulder portion of said fiat resilient arm on the return movement of said trigger for pivoting said arm on said trigger and maintaining the feed member on the arm out of contact with said paper during such return movement so as to prevent tearing or displacement of the paper upon such return movement.
