PAPER RUPTURE PISTOL poration of New York Application October 29, 1936, Serial No. 108,161

18 Claims.

This invention relates to toys, and more particularly to a toy weapon which produces a percussive report by pneumatically rupturing paper.

The object of my invention is to generally improve toy weapons, especially of the paper rupture type. More particular objects center about and are to improve the mechanism for retracting and releasing the piston, the mechanism for operating the paper clamping or paper sealing device, and the mechanism for holding and feeding the paper in the toy.

To the accomplishment of the foregoing general and other more particular objects which will hereinafter appear, my invention consists in the paper rupture toy elements and their relation one to the other as hereinafter are more particularly described in the specification and sought to be defined in the claims. The specification is accompanied by drawings in which:

Fig. 1 is a side elevation of a toy pistol embodying features of my invention, with one side of the pistol casing almost wholly cut away;

Fig. 2 is a horizontal section taken in the plane of the line 2-2 of Fig. 1;

Fig. 3 is a section taken in elevation in the plane of the line 3 3 of Fig. 2;

Fig. 4 is a similar View showing the relation of the parts near the end of the trigger movement;

Fig. 5 is a similar View showing the relation of the parts at the end of the trigger movement;

Fig. 6 is a transverse section taken in the plane of the line 6 6 of Fig. 1'; and

Fig. l is a horizontal section taken in the plane of the line 'l-'l of Fig. 1 and showing the paper feed mechanism.

Referring to the drawings, the paper rupture toy simulates a pistol adapted for rapid ring. The pistol'comprises a cylinder l2 mounted ne'ar the muzzle of the gun, and a piston I4 reciprocable in said cylinder. The piston is secured at the forward end of a piston rod I6 around which is coiled a main compression spring I8. The forward end of spring I8 bears against piston I4, and the rear end of spring i6 bears against the forward wall 26 of a frame 22 mounted within pistol body 24. The piston is thus normally urged forward by spring i8 to the position shown in Figs. 1, 2, and 3.

A strip of paper P is fed past the muzzle of the gun from a paper roll R by appropriate paper feed means F. The paper is clamped against the muzzle of the gun by a clamping ring C, as is clearly shown by the change in the relation of the parts from Fig. 3 to Fig. 4. The piston is then released without, however, releasing the clamp C, and the resulting compression of air within the cylinder bursts the paper film at the muzzle of the gun, with a loud report. The relation of the parts at this time immediately after firing the gun, is shown in Fig. 5. 'I'he clamp C (Cl. l16-195) is then released and a new section of paper is fed to the muzzle of the gun', as is indicated in Fig. 1. The various movements above outlined are obi tained by a simple pull on trigger T which, during the first part of its movement, draws the piston rearwardly to tension the main spring I8, and also draws the clamp ring C rearwardly to seal the paper at the muzzle of the gun. At the end of the trigger movement the piston is abruptly released without, however, releasing the clamp C, thus firing the gun. During the forward or return movement of the trigger, the clamp C is released and the paper is fed forwardly from the paper roll.

Considering in greater detail the mechanism by which this desired operation is accomplished, the trigger T is oscillatably mounted at its upper end on a pin 26 extending transversely through the frame 22. Asis best shown in Fig. 2, the side Walls of the frame are indented at 28 to prevent sideward movement of the trigger and to countersink the riveted ends of pin 26. In the particular arrangement here illustrated, the pin 26 is located at the same elevation as the piston rod I6, and the latter is therefore slotted at 30 to aiford free reciprocation of the rod with respect to pin 26.

Trigger T is made of a single piece of sheet metal which is reversely bent to have a U shape in section. The trigger is thus formed with side walls 32 and a forward wall 34. The latter is preferably rounded and may be given a sinuous or indented shape to more readily fit the fingers of the operator. The trigger does not require and is preferably devoid of rear and bottom walls. The side walls 32 are projected upwardly to receive the pivot pin 26, but the forward wall 34 is terminated well below the piston rod I6, thus enabling the piston rod to pass between the side walls 32.

Trigger 32 carries a cam element 36, and piston rod I6 is provided with a cooperating cam follower 38. As is best shown in Fig. 2, the cam follower 38 preferably passes through and projects on opposite sides of the piston rod i6. Cam element 36 is preferably formed of a single piece of sheet metal bent upwardly to form side walls 46 adapted to straddle the piston rod i6, and a bottom wall 42 which interconnects the side walls 4l). The entire element is pivotally mounted on trigger T by means of a pin 44. The element 36 is normally urged in a clockwise direction by means of a wire spring 46 the upper end 48 of which bears against the top of the pistol body, and the lower end 56 of which passes through a hole in bottom wall 42, as is best shown in Fig. 3. The resulting oscillation of cam element 36 is limited by motionlimiting stop lugs 52 struck inwardly from the side walls 32 of the trigger.

It will be clear from inspection of Fig. 3 that as trigger T is drawn rearwardly, the cam element 36 moves upwardly and rides in front of the cam follower 38. The shape of the rear edge of cam element 36 is such that as the trigger is moved, the cam element forces the cam follower and with it the piston rod rearwardly. Thus, in Fig. 4 the trigger is shown near the end of its rearward movement, and it will be noted that the upward movement of cam element 36 against cam follower 38 has forced the cam follower and piston rod rearwardly, the piston Hl then being near the rear end of cylinder |2. In the particular construction here illustrated, the rear end of the piston rod passes through the rear wall 54 of the frame 22 and through the rear end or breech of the pistol body. The frame 22 may, if desired, be provided with a bearing pin 56 carrying an anti-friction roller 58 beneath which the piston rod i6 rides. This is desirable in order to eliminate friction and in order to obtain smooth easy operation despite the upward component of force impressed on cam follower 38 by cam element 86 during its upward movement.

In order to release the piston rod at the end of the trigger stroke, the cam element 36 is preferably provided with an escape passage through which the cam follower 38 readily passes. Specifically the side walls 40 of the cam are displaced outwardly to form the channel-shaped passages 60 which are most clearly shown in Figs. 2 and 6. The width of the channels or passages 66 exceeds the diameter of the cam follower 38, and the outward displacement of the passages is such that the distance therebetween exceeds the axial length of the cam follower. Referring to Fig. 4, it will be seen that near the end of the trigger stroke the escape passage 6|) approaches the cam follower 38; and referring to Fig. 5 it will be seen that at the end of the trigger movement the escape passage 68 is brought into direct alignment with cam follower 38, thus permitting the latter to shoot forwardly through the cam element 36.

On releasing the trigger, the spring 46 previously mentioned functions to restore the trigger to the forward position shown in Figs. 1 and 3. During this return movement of the trigger the cam element 36 oscillates counter-clockwise away from the motion-limiting stops 52, this movement being caused by engagement of the forward edge of the cam element with the cam follower 38. When, however, the trigger reaches its foremost position, the end of cam element 86 passes below cam follower 38, and the cam element is oscillated in a clockwise direction against motionlimiting stops 52 and assumes the initial position shown in Figs, l and 3. At this time the relation of the parts is such that on pulling the trigger rearwardly the cam element again comes in front of the cam follower and again functions to move the piston I4 rearwardly against the compression spring |8,

The mechanism for moving the clamping means C against the paper at the muzzle of the gun is next described. The clamping ring is preferably struck from heavy-gauge sheet metal and provided with a pair of long diametrically extending arms 62 which are bent rearwardly, as is best shown in Figs. 1 and 2, to form guide links for guiding and moving the ring. Guide links 62 pass outside of cylinder I2 but preferably inside of the pistol body, as will be clear from inspection of Figs. 1 and 2. The links are thus wholly concealed except for that portion which extends beyond the muzzle of the gun. Links 62 are stepped inwardly somewhat at 64 and then extend rearwardly, as indicated at 66, in contact with the opposite sides of frame 22. The ends of the links are connected by a pin 68 which extends through and is movable in slots TID (Figs. 1 and 2) cut through side walls of frame 22. Pin 68 also extends through a slot l2 (Figs. 2 and 3) cut through piston rod I6. Slot 'l2 is so located that piston rod I6 cannot move rearwardly without drawing the links 62 rearwardly with it, but the piston rod may move forwardly without the links, as is illustrated in Fig. 5. The links are normally urged forwardly by a spring 14 the U- shaped center portion 'I6 of which is anchored in the bottom of frame 22, and the forward ends 'I8 of which are anchored in appropriate lugs 88 bent inwardly from links 62. When the links are drawn rearwardly the spring is bent to the position shown in Figs. 4 and 5, but when the links are released the spring moves the links forwardly and assumes the position shown in Figs. l and 3.

To hold the links in retracted position in order to clamp and seal the paper membrane at the muzzle of the gun while the piston is impelled forwardly, I provide suitable stop means moved by and preferably mounted on the trigger T. The stop means is indicated at 82 and may be formed directly on the trigger, but in the present instance has been formed on the cam element 86. The side walls of the cam element are projected upwardly to form a pair of stops 82 so disposed as to straddle the piston rod |6 when the trigger is moved to rearward position. Thus, referring to Fig. 4, it will be seen that near the end of the trigger movement the stops 82 begin to move in front of the pin 68 which extends from one link to the other, and referring to Fig. 5 it will be seen that when the trigger is moved to rearmost position, thus releasing the piston rod for forward movement, the stops 82 are disposedV directly in front of pin 68, thus holding the clamping ring C tightly against the muzzle of the gun. The rear edges of stops 82 may be given a slight curvature in order to obtain a camming pressure against pin 68, which insures air-tight sealing of the paper membrane.

Of course, on releasing the trigger the stops 82 move downwardly from in front of pin 68, and the links 62 and with them the clamping ring C are moved forwardly by spring 14.

The paper roll R turns about a stationary pin 86 which projects sidewardly from wall 86 (Fig. 7) of the gun housing. The piny is securely anchored to wall 86 at one end, the other end of the pin being left free and unsupported in order to facilitate the slipping of a roll of paper thereover. At the free end of pin 84 the gun housing is provided with a closure 88 pivotally mounted at 98 so that the closure may be moved rearwardly to the broken-line position shown in Fig.

4, at 88', thereby opening the paper chamber. The strip of paper is fed from the top of roll R along the upper side of a paper guide channel S2. This channel is curved smoothlyV upwardly and is secured to the clamping ring C by bent tongue connections 94. The side walls of the channel guide vthe paper accurately across the aperture 96 through the clamping ring, as is clearly shown in the drawings. Near the rear end of the paper guide channel 92 the side walls are enlarged and form supports 98 for a pin |80 on which is pivotally mounted a paper feed dog |62. The dog |82 is normally urged downwardly by a small leaf spring |84 the forward end of which is secured, as by welding, to dog |02, and the rear end of which rests on a resilient member |06. As is best shown in Fig. '7, the dog |02 is a plate provided at its lower edge with a pair of tangs or points |08. The bottom surface of the paper guide channel 92 is preferably depressed to form grooves H in which points |08 slide. This insures penetration of the paper by the points, and accurate feed of the paper. The points |08 are, of course, spaced apart an amount greater than the diameter of the apertures in the muzzle of the gun and the sealing ring, and the minute perforations made by the points |08 do not affect the air-tightness of the paper membrane.

The member |06 is secured at its rear end to the bottom wall of the gun housing, the attachment preferably being at one edge, as is indicated by the eyelets |2 in Fig. 7. The advantage of attaching the member at one edge is that there is no interference with opening of the gun casing by separation of the halves thereof. The forward end of member |06 rests on the paper being fed over the guide channel 92 and functions to frictionally restrain the paper against movement and to prevent escape of the paper from the guide channel. Moreover, the member |06 is made to act as a holding pawl for the paper, and to this end a pair of tangs or points ||4 are formed on and struck downwardly from the member, the said tangs being aligned with the tangs |08 and being disposed over and cooperating with the grooves ||0 previously referred to.

In operation, it will be understood that during rearward movement of the trigger and rearward movement of the clamping ring C, the feed dog |2 slides rearwardly over the paper in the guide channel 92, and the paper is prevented from moving rearwardly with the guide channel by the holding dogs Mii. After the gun has been red and during release of the trigger, the clamping ring C moves forwardly, and at this time the holding dogs im merely slide over the paper, while the feed dog |02 draws a new section of paper from the paper roll R.

The casing or gun body 24 is preferably formed of two pieces of sheet metal each having a side wall and peripheral flanges adapted to be brought into edge to edge relation to complete the gun body. Simulated sights |20 may be used to hold the parts in registration, and these and other points on the gun body may be provided with appropriate tongue and slot connections one of which is indicated at |22 at the bottom of the gun handle. (The others have been omitted to simplify the drawings.) At the muzzle of the gun the halves of the gun body are held together by a ring l2ii which fits tightly over the gun body and which is recessed at the sides to receive the guide links E2. The forward end of cylinder l2 is flanged inwardly and the parts are provided with a rubber sealing ring or gasket |26 the nature of which will be clear from inspection of the drawings. This sealing ring provides a yieldable surface against which the paper may be compressed to form an air-tight seal.

The frame 22 is made up of two pieces of heavy-gauge sheet metal bent to provide side walls and end walls secured together by appropriate bent tongue and slot connections indicated at |27 (Figs. l, 2, and 3). Referring to Figs. 2 and 6, it will be noted that the top and bottom edges of the side walls are turned outwardly to form spacer flanges |28 which centralize the frame between the side walls of the gun body. The flanges |28 are preferably provided with tongues |30 which pass through mating slots in the gun body and are bent to securely lock the frame 22 within the gun body.

It is believed that the construction and operation as well as the many advantages of my improved paper rupture gun, will be apparent from the foregoing detailed description thereof. The

gun 1s both cocked and fired by movement of thel trigger alone, yet the trigger movement is made smooth and easy by the cam mechanism employed for compressing the main spring. The manner in which the clamping ring is held in paper sealing position while the piston is released for forward movement, insures dependable operation of and long life for the mechanism. The paper is tightly sealed and maintained in that condition during the firing stroke, and a loud report is obtained each time the gun is red, regardless of how rapidly the trigger is repeatedly pulled.

It will be apparent that while I have shown and described my invention in a preferred form, many changes and modifications may be made in the structure disclosed, without departing from. the spirit of the invention, defined in the following claims.
