Application February 19, 1954, Serial No. 411,353

1 Claim. (Cl. 42-54) This invention relates to toy guns for exploding fulminate caps and the like of the type referred to as paper caps which consist of small charges of explosive powder confined between sheets of paper.

It is common practice to place fulminate caps in toy guns and release a hammer or other impact member of the gun to strike the cap and fire same to produce sound effects which provide enjoyment for children, however, the shape of the gun and the noise created by the firing of the caps are the only similarities in such toy guns to the firing of a real firearm such as a rifle or pistol.

The principal objects of the present invention are to provide a novel toy gun utilizing the usual paper fulminate caps with a cap receptacle and cooperating bolt or hammer which enclose the cap and prevent scattering of particles thereof when exploded; to provide such a toy gun in which the frame is light in weight and the bolt or hammer plunger is relatively heavy and in which the plunger is released and driven toward the person firing the gun to strike a cap in a cup-like receptacle having side walls which sleeve over the bolt whereby the explosion of the cap is substantially confined by the cup and bolt and said explosion cooperates with the force of the impact of the bolt to effect a recoil in the gun that approximates or is similar to that experienced in shooting a real firearm; and to provide a toy gun that is economical to manufacture, sturdy in construction and safe in operation in simulating both the sound and recoil of a firearm.

In accomplishing these and other objects of the present invention we have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective view of a toy gun embodying the features of the present invention.

Fig. 2 is a longitudinal vertical section through the gun.

Fig. 3 is a longitudinal vertical section through the gun with the parts thereof in cocked position ready for firing.

Fig. 4 is a vertical transverse sectional view through the gun on the line 44, Fig. 2.

Referring more in detail to the drawings:

1 designates a toy gun which generally consists of a barrel 2, a breechblock 3, a bolt or plunger 4, handle or stock 5 and trigger 6.

In the illustrated structure the handle or stock 5 has its entire upper surface 7 provided with a longitudinal groove 8 which provides a seat for the barrel 2. The rear portion of the stock extends downwardly and is shaped to provide a handgrip 9 and the forward portion 10 extends from the handgrip and terminates as at 11 in spaced relation to the muzzle end 12 of the barrel. The stock 5 has an elongated recess intermediate the front and rear ends thereof and extending from the bottom of the forward extension 10 to the groove in the upper face of the stop. A slot 13 is positioned forwardly of the handgrip and is of a width to receive the trigger 6.

The trigger 6 is located in the slot 13 and comprises substantially a bell crank pivotally mounted on a trigger 2,814,144 Patented Nov. 26, 1957 pin 14 located adjacent the upper portion of the slot 13 between the vertical side walls of the slot 13. The trigger has a downwardly extending portion which extends below the bottom of the slot 13 to provide a trigger pull 15. The other arm 16 of the trigger extends forwardly in the slot 13 and terminates in a trigger lug or sear 17 which extends upwardly from the arm 16 and has a flat front edge 18 and a rounded or curved rear edge 19. The lower portion of the arm 16 under the sear 17 is notched as at 20 for engagement of one end of a compression spring 21, the other end of the compression spring being in engagement with the bottom 22 of a recess 23 that extends downwardly in the side walls of the slot 13 from the groove 8.

The barrel 2 has a bore 24 extending rearwardly from the muzzle end thereof, and said muzzle end of the bore is preferably threaded and a plug 25 screwed therein, said plug having a bore 26 for slidably receiving a plunger or bolt rod 27 of the plunger or bolt 4. The rod extends through the plug bore 26 and has a knob 28 secured on the forward end thereof which is gripped for pulling the rod in cocking the gun, as later described. In the illustrated structure the barrel 2 has a breechblock 3 secured in the rear portion thereof and the barrel is secured to the stock by means of a screw or other suitable fastening device 29 which extends through

aligned apertures

30 and 31 in the barrel and breechblock respectively and is threaded into the stock, with the forward end of the barrel held in seated relation in the groove 8 by means of a band 32 tightly sleeved over the barrel and forward end of the stock. A pin 33 extends into aligned apertures in the forward portion of the stock and bottom of the barrel to maintain the forward end of the barrel in alignment.

The bottom wall of the barrel is provided with a slot 34 aligned with and of suitable size for passage of the trigger sear therethrough. The rear end of the rod 27 is threaded or otherwise suitably secured to a plunger or bolthead 35 which is a relatively close fit, yet freely slidable in the bore 24 of the barrel. The spring 36 is sleeved on the rod 27 between the plug 25 and the bolthead 35 whereby when the knob 28 is pulled to draw the plunger rod forwardly of the barrel sufiiciently to move the plunger or bolthead 35 beyond the forward edge 18 of the trigger sear 17 the spring 21 will urge the trigger sear upwardly into the barrel in engagement with the striker end 37 of the plunger head to retain same in cocked position, the spring 36 being of suitable length and size, when compressed when the gun is in cocked position, to propel the plunger or bolt with desired force upon release thereof by actuation of the trigger.

A loading opening 38 is arranged in the upper portion of the barrel and spaced forwardly from the front surface 39 of the breechblock 3, whereby the portion of the barrel immediately forward of said face 39 cooperates therewith to form a cup for receiving suitable fulrninate caps 40. The opening 38 is of suitable size to permit insertion of the caps and also for use of a cleanout instrument 41 in the removal of paper particles that remain in the cap receiving cup. The cleanout instrument is preferably a rod 42 having an eye 43 on one end thereof and when not in use the rod is suitably stored as by inserting same in a bore 44 in the lower end of the handgrip as illustrated in Fig. 2, the bore and rod being tight fits whereby friction retains the cleanout instrument in place. While the breechblock and the cup forming portions are shown as a part of the barrel, it is believed obvious they can be separated. However, whether connected or separated the cap receiving cup must be aligned with the bore of the barrel and also be a relatively close fit to the periphery of the plunger or bolthead. The stock and barrel are preferably made of light weight materials and the bolt on plunger 4 is of relatively heavy material whereby the greater portion of the recoil from the impact of the plunger on the breechblock is transmitted to the user and is not absorbed by the gun frame.

To operate a gun constructed as described, it is necessary to pull forward on the knob 28 until the plunger or bolthead 35 is moved forwardly of the sear 17, whereby the spring 21 swings the trigger 6 to move the sear upwardly through the slot 34 into the barrel behind the plunger or bolthead to retain the plunger or bolt in cocked position with the spring 36 compressed between the plunger or bolthead and the plug 25. Then a fulrninate cap 41) is inserted in the cup and positioned to rest against the forward face 39 of the breechblock. To discharge the gun the user grips the handgrip 9 and applies rearward pressure on the trigger pull 15 whereby the same is swung in a clockwise direction on the pivot pin 14 and also moves the sear 1.7 to disengage same from the plunger or bolthead 35. The spring 36 then propels the plunger or bolt rearwardly whereby the end 37 of said plunger or bolthead strikes the cap detonating same. The relatively close fit of the rear end of the plunger or bolthead 35 in the cap receiving cup confines the force of the explosion whereby said explosion acts on the breechblock to provide a recoil effect. Also the impact of the plunger or bolthead against the breechblock provides a recoil effect on the person firing the gun. The combined force of the impact of the bolthead against the breechblock and the explosion of the cap 40 is preferably such that the recoil approximates or is similar to that experienced in shooting a real firearm.

After the gun is fired the knob 28 is again grasped and pulled forward to cock the gun, and then the cleanout instrument 41 is removed from the handgrip and the point of the rod 42 used to remove any paper particles remaining in the cup at the forward end of the breechblock. The cup is then ready to receive another cap to be fired in the gun.

It is believed obvious that we have provided a novel toy gun for exploding fulminate caps and the like wherein the firing provides a recoil effect that simulates that of the firing of a real firearm.

What we claim and desire to secure by Letters Patent A toy gun of the character described comprising, a

barrel having a muzzle at one end and a breechblock at the other end thereof, a gun stock, means securing the barrel on the gun stock, said barrel and breechblock and gun stock being relatively light in weight, said barrel and breechblock cooperating to form a cylindrical shaped cup adjacent the forward end of the breechblock for receiving fulminate caps to be fired therein, said cup having a striker face at its rear end and a continuous peripheral wall extending a substantial distance forwardly from the striker face thereby defining a forwardly opening cup, said barrel having a lateral opening therein at the forward end of the cup whereby the caps may be inserted into the cup, a relatively heavy bolt slidably mounted in the barrel and having a cylindrical striker portion on the rear thereof shaped and dimensioned to be received in said cup with a relatively close fit, a face on the rear end of the striker portion of the bolt corresponding in shape to that of the striker face at the rear of the cup, trigger means engageable with the bolt for holding same spaced forwardly from the breechblock, and spring means in the barrel between the bolt and the muzzle and operative to propel the bolt rearwardly and the striker portion thereof into the cup and against the striker face at the rear of the cup explodingthe cap therein upon release of the trigger means from the bolt, said striker portion extending rearwardly of the opening in the barrel and into the cup in close relation to the peripheral wall thereof when the bolt is propelled rearwardly thereby defining an enclosed chamber in the cup whereby the explosion is substantially contained and the combined forces of the explosion and impact of the bolt produce a recoil simulating shock in the gun stock.
