TOY CANNON.

Application ined July 11,

vention resides in thedetails of construction of the magazine of the gun whereby the same is formed up and completed,simultaneously with effecting its rigid association with the gun barrel.

The invention, inits preferred embodiment, is fully illustrated in the accompanying drawings, wherein z-f Figure 1 is a central vertical longitudinal section of a magazine gun constructed in accordance with the invention.

Figure 2 is a similar view showing the gun plunger' drawn back preparatory to release thereof to eject a projectile.

Figure 3 is a fragmentary top plan view of the gun and its magazine.

Figures 4 and 5 are vertical transverse sections .on the lines 4 4 and 5-5 respectively, of Figure 1.

Figure 6 is a perspective view of a projectile for the gun.

Figure 7 is a plan view of a sheet metal blank of which the magazine is made.

The gun comprises the barrel 1 having a cylindrical bore 2 closed at one end by means of the breech-block 3 which may be composed of wood, cork or other material, the gun barrel being preferably made of wood.

In the breech-bloclr 3 isa central opening.

axially coincident with the bore 2 and through which one end portion of the plunger 4 passes freely, said plunger being provided between its ends with an annular enlargement 5 substantially fitting. the bore 2. A helical compression spring 6 `is interposed between the portion 5 of the plunger and the breechblock 3. The outer end of the plunger 4'is equipped with a handle element 7 whicliis cylindrical and is provided between un amis with an annular garen-ve a to permit tion, the lateral and longitudinal dimensions 1927. Serial No. 204,750.

the same to be easily digitally engaged for drawing back against the action of the spring 6 as shown in Figure 2. The outer end of the plunger 4 enters a central bore in the element 7 and is preferably secured to the latter by means of the key-pin 9.

The gun barrel 1 is provided between its ends in the uppermost portion of its cir` cumferential wall with a longitudinal slot `1() through which the projectiles 11 enter the bore 2. Fitted to the barrel 1 is a tubular magazine 11 made preferably of sheet metal and which is of rectangular cross-secof said magazine 11 being such that the lower vends of the end walls thereof fit snugly telescopically within the slot 10 at the ends of the latter.` The side walls of said member 11 are provided midway 'between their side edges with longitudinal indentations forming ribs 12 interiorly of the tube 11, the

lower ends of said ribs providing projections 13 which extend into the slot 10.

The said magazine member is composed of a single piece of sheet metal which, as shown in Figure 7, illustrating the blank before forming, comprises two side wall portions `14 and 15 respectively, connected with each other by intermediate strap-portions 16 spaced from each other by the longitudinal slot 17. The vportion 14 is of such greater width than the portion 15 as to include the end-wall port-ions 18 adapted to be bent at right angles to the middle portion thereof along the dotted lines 19. At the side edges of the portion 14 are two pairs of lugs or flanges 2O andV at the side edges of the portion 15 is one pair `of lugs or flanges 21 all of said lugs or flanges being bent to extend at right angles to the `adjoining side edge j portions of

saidk portions

14 and 15 of the blank` after the latter is bentto cause the saidv portions to become opposed to each other to form the tube 11, the lugs or flanges 20 then overlapping the outer faces of the portion 15 and the lugs or flanges 21 then overlapping the end wall portions of the portion 14 of said blank to thereby securely lock the walls of the tube 11 against rela- 100 tive displacement. It will be understood,

of course, that the'. rib forrlrziations are pro@ ltl end- 'alls are `sprung into the slot 1t) o'l the4 barrel. The several lugs or flanges 2O and 21 are then bent as above described to com-k plete the magazine tube 1l and. at the same time, secure the same rigidly to the gun barrel. The latter is provided with an annular shallow groove to receive the said strap-portions 1G, the outer side edges of which engage the annular shoulders at the ends ot' .said grooves to prevent longitudinal movement of the magazine relativelyY to the gun barrel.

At the upper ends ot the ribs 12 I provide indentations which form opposed projections Q5 spaced from cach other a distance slightly less than the diameter of the middle or annular groove portions Q4 of' the c vlindrical projectiles 25, the end portions ot which are of a diameter ,slightly less than that of the bore 2 ot the gun barrel 1, the total length ot each projectile heilig somewhat less than the longer diameter otv the magazine 11j.I the ribs 12 ot the latter preventing the ends of the projectiles from coming into contact with the end walls ot the magazine to thereby more efl'cctually prevent canting of said projectiles.

The operation ol` the device will be very readilj7 understood without further description.

I claim as m v invention:

1.The combination with a gun barrel having a longitudinal slot between its ends, ot a magazine tube mounted on said barrel and communicatiiig at its discharge end with said slot'` inwardly extending guide formations on opposed walls of said tube` and .projectiles provided with guide formations between their ends for cooperation with the formations ot said tube to prevent canting ot said projectiles.
