TOY MACHINE-GUN.

Specification of Letters Patent.

rammed a t. 2e, rare.

Application filed February 17, 1919. Serial No. 277,4=98.

To all whom c't may concern:

Be it known that I, FRANCIS VICTOR DU PONT, a citizen of the United States, and a resident of Wilmington, in the county of New Castle and State of Delaware, have invented a new and useful Improvement in Toy Machine-Guns, of which the following is a specification. r v

My present invention relates generally to toy machine guns and particularly to a continuousrapid-firing toy gun, my object being the provision of an improved device of this nature which will be durableand pleasing, and in; connection with which considerable range may :be given the" discharged bullets and guns of different ranges readily constructedalon the same lines.

Other and rther objects relating for the most part to the details of construction of the gun and the ammunition therefor will be apparent from the following description, wherein reference is made to the accompanying drawings forming apart of this specification and wherein Figure 1 is a perspective view of the gun complete ready for operation,

Fig. 2 is a vertical longitudinal section taken therethrough,

Fig. 3 is a longitudinal horizontal section,

Fig. at is a vertical transverse section taken substantially on the line l4 of Fig. 2,

Fig. 5 is a plan View of a portion of the ammunition, parts being broken away and in section.

Referring now to these figures my invention proposes a toy gun structure in which the barrel 10 is preferably integral with the lower portion of the rear breechblock 11 and may be supported in any suitable manner as by means of a frame 12 including supporting legs 13 and attached in any suitable manner to the lower portion of the breechblock 11.

The upper surface of the lower portion of the breechblock terminates slightly below the bore of the barrel 10, the latter preferably having a lining 14E of any suitable mate rial designed to reduce friction of the projectiles passing therethrough, the rear end of the opening through which alines with an openin 15 as seen inFig. 3 in particular, forme through the front wall 16 of a breech casing 17 secured horizontally within the upper portion of the breechblock 11 and open at the opposite sides of the breechbloek. This breech casing 17 extends materially beyond one side of the breechblock 11 and its front wall 16 has a forwardly flared portion 18 gradually enlarging the casing in a direction parallel to the axis of the barrel 10, toward its laterally opening mouth within which the projectiles areu'eceived with their axes slightly inclined with respect to the aXis of the barrel 10, the casing having a head 18 at the rear'of its mouth.

Within the breechblock' the casing 17 has forward and rear transverse slots19 registering with recesses 20 of theibreechblock as seen in Fig-2, in'which the arms 21 are movable. These arms are secured to and project from a shaft- 22fijourn aled in the lower portion of thebreechblock liparallel to the axis of the barrel. lO'and provided with a rearwardly eiiten ding'crank 23 at the rear of the breechblock whereby the shaft 22 may be rotated, thus bringing the arms 21 successively through the slots 19 of the casing 17 for a purpose which will be presently described. y

Hinged at its rear edge to the rear edge of the breechblock 11 is abreech cover 24,

normally secured to the casing'17 by means of a pivoted catch 25 carr'ied'by the rear end of the barrel 10 and movable onto and away from the forward edge of the said cover 24.

The ammunition is preferably in the form of an endless web 25 as seen in Figs. 1, 4 "and 5 in particular, having at spaced points of its length transversely disposed and slightly inclined tubular holders 26 which 'are closed at one end at one side of the web and open at their opposite ends, each of these tubular holders having a spring 27 coiled therein and being adapted to receive at the open end thereof one end of a cylindrical projectile 28 which is preferably solid. In the normal extension of the projectiles 28 within their tubular holders 26, the combined length of the projectile and holder exceeds the length of the breech casing 17 within the breechblock 11, while this length is slightly less than the length of the ammu nition receiving mouth of the said casing at one side of the breechblock.

Thus as each successive projectile of the ammunition web passes into the receiving mouth of the breech casing its projectile 28 is gradually forced inwardly of its respective holder 26 and against the tension of the respective spring 27 by the sloping portion 18 of the front wall 16 of the breech casing without danger of binding. Movement of the ammunition web is brought aboutby rotation of the shaft 22 through its handle 23, the arms 21 engaging successive holders 26 as seen particularly in Fig. 1, so asto shift the ammunition belt in intermittent movements through the breech casing.

It is obvious that, during the just described movement of the ammunition belt, and as each projectile 28 comes into registry with the rear end of the bore of the barreh the respective spring 27 will act to propel the projectile free of its holder 26 and through the opening 15 in the front wall of the casing 17 as well as through the tubular lining 14L of the barrel 10. It is thus obvious that firing of the projectiles may be made as rapid as desired by rotating the handle 23 fast or slow as the case may be and it is to be understood that the projectiles 28 which are normally telescoped partly within their holders 26, have just sufiicient engagement therewith to prevent their accidental displacement before passing into the receiving mouth of the breech casing.

It is also to be readily seen that the range of the gun may be readily controlled by simply regulating the strength of the springs 27 within the several projectile holders 26, and it is obvious that for the purpose of my in vention the web 25 connecting the several holders 26 need not be endless as shown, although this is to be desired in a toy by virtue of thefact it will normally remain in connection with the gun so as to avoid accidental displacement at a loss. It is, of course, to be understood that the barrel 10 need not be lined although its lining 14 will avoid a great deal of friction otherwise existing between the several projectiles and the barrel in the passage of the projectiles therethrough, as in practice the projectiles would in all probability be made of the same or similar material to that of the barrel 10.

Should the ammunition belt or any of the holders 26 get out of order or become worn to the point of breaking, it is obviously possible to readily and quickly repair the same and should the rear end ofthebarrel become clogged it is simply necessary to release the catch 2 4: and raise the breech cover 24 upon its hinged connections with the breechblock so asto expose the rear end ofthe bore of the barrel and the interior of the breech casing 17 I claim 1. The combination with a gun having a barrel and a breech in communication with, and opening at opposite sides of the rear of, the said barrel, of ammunition therefor including a plurality of connected holders and projectiles movable into and out of the holders, the said holders having internal springs for expellingthe projectiles through the barrel, against whichthe projectiles are compressed within theheldersiflthe breech,

said breech having a casing provided with a laterally projecting flared receiving mouth through which the ammunition is initially movable, as described.

2. The combination of a toy gun having a barrel and a breechblock at the rear of the barrel provided with a transverse open ing extending through its opposite side and in communication with the bore of the barrel, of ammunition including a plurality of connected holders and projectiles telescoping within the holders and movable through the breech opening, to successively register with the bore of the barrel, each of said holders having an internal spring against the tension of which the respective projectile is compressed in its movement through the breech, and means mounted in connection with the breech for feeding the ammunition within and through the breech.

3. A toy gun comprising a barrel, a breechblock at the rear end of the barrel having a transverse opening extending through its opposite sides and in communication with the rear end of the bore of the barrel, and a breech casing within the breechblock having aflared receiving mouth projecting laterally beyond one side of the breechblock as described.

a. A toy gun comprising a barrel, a breechblock at'the rear end of the barrel having a transverse opening extending through its opposite sides and in communication with the rear end of the bore of the barrel, and a breech casing within the breechblock having a flared receiving mouth projecting laterally beyond one side ofthe breechblock, said breechblock being in two parts hingedly connected to one another and one ofwhich parts is movable with respect to the other to expose the breech opening.

5. Ammunition for toy guns consisting of a flexible web, a plurality of tubular holders disposed transversely of the web and open at one end, projectiles telescoping within the open end of the said holders and springs within the holders and against which the projectiles are compressible for the purpose described.

tile holders for engagementby the arms of the said shaft so as to vshift the ammunition through the breech opening, as described.

7. A toy gun comprising a barrel having a bore, a breechblock at the rear end of the barrel, having a transverse breech opening through its opposite sides, a breech casing disposed Within the breech opening, and having an opening in its front Wall registering with the bore of the barrel, said breech casing having a flared receiving mouth extending laterally beyond one side of the breechblock, said breechblock being formed in upper and lower sections having hinged connections and one of which sections is movable to expose the breech casing, 15 and means for normally securing the said movable breech section in closed position.
