1 Claim.

My invention relates to toys and more particularly to toy guns of the compressed air type.

The object of my invention is to provide a toy gun having a barrel slidably supported by the breech or stock respectively and sliding rearwardly, when the gun is discharged, producing a fair imitation of the gun barrel movement caused by the recoil of a regular re arm.

Other objects of my invention may appear in the following specication describing my invention with reference to the accompanying drawings illustrating several preferred embodiments of my invention.

It is however to be understood, that my invention is not to be limited or restricted to the exact construction and combination of parts described in the specification and shown in the drawings, .but that such changes and modifications can be made, which fall within the scope of the claim appended hereto.

In the drawings:

Figure l is an elevational end view of a toy anti-aircraft gun according to my invention.

Figure 2 is a longitudinal sectional view taken on line 2-2 in Figure 1.

Figure 3 is a sectional view taken on line 3-3 in Figure 2.

Figure 4 is an elevational end view of the muzzle end of a modied form of a gun barrel according to my invention with a special projectile inserted therein.

Figure 5 is a sectional View taken on line 5 5 in Figure 4.

Figure 6 is an elevational side View of a toy pistol equipped with a floating barrel according to my invention, and

Figure 7 is an elevational side View of a toy shot gun or rifle equipped with a iloating barrel according to my invention.

Referring now in detail to the drawings and the anti-aircraft toy gun shown in Figures l to 3 has a substantially rectangular base I0, which can be made from any suitable material. Centrally therein a pivot pin II is embedded or securely inserted and extends upwardly therefrom.

A revolving base I2 has a centrally located hole I3 therein adapted to receive the pivot pin I I therein, so that the revolving base can be rotatably mounted on the stationary base Ill. The revolving base I2 is narrower than the stationary The ends I6 and I center of which coincides with the center of the arcuate ends I6 and Il of the revolving base I2.

A worm 2&3 is rigidly mounted on a shaft 2|, which is rotatably supported in a plurality of bearings 22 formed on a bracket 23 securely fastened onto the stationary base I@so that the worm 2G engages the sector worm gear. On one end of the shaft 2E a crank handle 2li is formed.

Two upwardly extending gun mounts 25 are rigidly mounted on the revolving base I2 at a distance from and parallel toeach other and to the longitudinal edges of the revolving base. Adjacent its upper edge and centrally of its width each gun mount 25 is provided with a hole, the purpose whereof is to be described later.

A gun breech 26 has a comparatively long front bore 2l' and a comparatively short rear bore 23 therein, and these two bores are connected with each other by a hole 29.

A stove bolt 39 extends through the holes in the two gun mounts 25 and a hole 30a is provided in the breech 2% so that the gun breech is supported rockably by said mounts. A washer and nut on the bolt 3G serve to force the gun mounts inwardly, increasing the rigidity thereof. A sector worm gear 3i is rigidly mounted on one side of the gun breech so that it extends downwardly.

On the inner surface of the adjacent gun mount 25, two bearings 32 are firmly mounted supporting a shaft 33 rotatably therein. A worm 3d is rigidly mounted on said shaft between the two bearings 32 and an opening 35 is provided in the gun mount to accommodate the worm, which meshes with the sector Worm gear 3l. On one end of the worm shaft 33 a crank handle 36 is formed.

A comparatively long gun barrel 3l has an open muzzle end and a closed rear end. In the rear wall 38 a hole 39 is provided and is arranged coaxially with the barrel S7. A piston rod 4) extends through hole 39 in the rear end wall 3S of the barrel 3l and on the front end of said piston rod, located inside the barrel, a piston il is adjustably mounted and is secured in adjusted position by means oi a nut l2 engaging a thread @3 provided on the front end of the piston rod di). A helical spring :it surrounds the piston rod 4d and engages the rear wall 38 of the gun barrel 3? with its rear end and the piston QI with its iront end.

The rear portion i5 of the piston rod d is threaded and extends through the hole 29 in the gun breech 2t. A washer i6 is mounted on the piston rod portion l5 and a nut 4l onthis piston rod portion urges said washer into contact with the rear end wall of the front bore 2l. A leather bolster or shock pad i8 is mounted on the piston rod d@ in front of the nut 31.

A second washer @9 is mounted on the part of the threaded rear piston rod portion i5 extending into the rear bore 2S of the gun breech 2t, and a second nut 5@ on said threaded piston rod portion #l secures said washer in permanent contact with the front wall oil the rear bore 28.

The outsidediarneter oi the gun barrel 31 is such that the barrel nts slldably in the front bore 2l of the gun breech 2t. The helical spring lid urges the barrel rearwardly into Contact with the shock pad di.

To cool: the gun the barrel 3l is pulled outwardly in relation to the breech 21%, A stop pin iii extends through a guide tube E52 inserted in the wall of the gun breech The stop pin 5i has an eye 53 on its lower end, and the end 5tV o a crank lever 55 engages this eye. rThe crank lever is pivot-ally mounted at on abracket 5l "astened tc the underside o' the gun breech 2li. ,e of the cranl: lever o is provided with an eye 5, to which a lanyard is attached and trained on a second bracket u2 on the underside ci the breech "il A coil spring 53s surrounding the pivot pin 5 urges the crank lever to raise the stop pin 5i into the gun breech and into the path of the barrel 3l, so that the barrel isssecured in cocked position.

The rear opening of the rear bore 253 of the breech 26 is closed by means of a plug or in any other conventional and desired manner.

W hen the barrel El is in cocked position a cor or any other suitable plug or wad is forced into the muzzle end of the barrel 3l'. The gun is aimed by training it by means of the ilrst mentioned worm 2li and sector worm gear i, and by elevating the breech ill by means of the second 35i and sector worm gear rthe stop pin iii is pulled downwardly actuating the crank lever 5:5 through the lanyard Sil, pern'iitting the gun barrel 3l to slide rearwardly into the gun breech. The air being compressed in the barrel 3l between the piston tl and the cork expels the latter from the barrel muzzie with a loud bang. The distance, to which the cork is projected, can be regulated by the tension of the spring dll in the barrel.

To protect the gun breech 2t against excessive wear by the sliding of the barrel a metal lining 65 may be provided in the forward end of the `front bore El in the gun breech.

Figures a and 2i illustrate a modification of the plugged front end et the gun barrel. In this modification the muzzle end of a gun barrel @l is provided with a plurality of blade springs 68 securely fastened onto the outer surface of the barrel, and having bent, forward portions Sil extending into the bore of the barrel through longitudinal slots iii in the barrel El, the foremost ends li of the bent spring portions il@ being shaped to extend outwardly through said slots. A stop pin 'le extends diametrically through the barrel at a distance rearwardly of the slots l@ and is secured in the circumferential wall of the barrel. A plug lf3, having a disk-like gasketfid fastened to its rear end fits slidably into the barrel El and has a semi-globular iront end l5. .he length or" this plug projectile riii is such that it engages the spring portions td inside the barrel tl' with its front end, when the gasket 'le is arranged in contact with the stop pin l2. rllhe gasket lil and the springs SSB increase the eniciency of the gun by producing a greater resistv ance against the displacement of the projectile "it from the barrel, so that a greater air pressure is needed to discharge the gun.

The rearward movement of the floating gun barrel under the pressure of the helical spring in said barrel produces the eiect of a barrel of a real anti-aircraft gun recoiling in consequence of being discharged.

vFigure d illustrates a gun barrel i8 oi the type described mounted on the stoel; li of a pistol'. The construction ci the gun barrel is exactly the same as described above, with exception that the stop pin 5l in the path ci the gun barrel isy retracted by means of a trigger 'il instead of a lanyard.

Figure '7 shows a rifle stock 'J8 equipped with a gun barrel di? and having a trigger l@ for retracting the stop pin el in the path ci said barrel.

Having described my invention I claim as new desire to secure by Letters Patent:

A toy pop gun comprising a holder having a barrel portion with a central bore and a support extending downwardly from the barrel portieri intermediate the length thereof, a. trigger pivoted on the holder forwardly of the support, said holder having an opening in its barrel por-- tion through" which the 'gger ina-y be extended, second barrel slidable within the central bore oi the barrel portion ci the h '.der, a rod exthrough the barrel and connected to the rear end oi the barrel portion of the c unger on the outer end oi the rod,

holder,

spring surrounding the rod and exan operating ten between the plunger the rear end of the second barrel to urge the rearw rd moveinent thereof, the forward or" the second barrel being adapted to receive a charge o inaterial, said trigger being adapted when extending through the opening the holder to engage the rear end ci the second barrel to normally retain in the extended position, rod being threaded on its rear end, an adjustable lock nut on the threaded end of the rod to retain the rod against rearward displacement and to allow for the proper adjustment oi the. rod within the second barrel, a cushioning means surrounding the rod and adapted to react against the rear end of the second barrer to lcushion and resist the rearward movement thereof at the end of its rearward stroke and upon the second barrel being released from the trigger, and a nut secured to the threaded end oi the rod tor retaining the saine on the holder against forward displacenient therefrom.
