1 This invention relates toa particularly to such a projectiler adapted for dis'- charge from a rie, gun, or the like.
A primary object of this invention is-theprovision of an improved projectile adapted to-pro- 4 bine the advantages of conventional fire, with rocket propulsion. Y y Y Asvconducive to a clearerl understandingof this invention, it may here bepointed out that'in normal rifle or` gun `iire, the propulsiveieie'ctfof a large quantity of the gases generated-1 by the explosion' is lost immediately after/the'bulletf-or -projectile leaves the barrel of a gun.
Conversely, in rocket propulsionthe eieot 'ofa material quantity of the gases of combustionis utilized in overcoming the initial inertia ofthe rocket shell. A primary object of1 this'invention, therefore, is the provision of an improved proijectile adapted to overcome both these disadvantages, and combine the best vpropulsive features of both gun-projected bullets androcket-pr pelled shells. j
Other objects will in part be obvious and in part be pointed out as the description of the invention proceeds. v
Still other objects reside in the combinations of elements, arrangements of parts, andi-'features of construction, all of which will be more fully pointed out hereinafter and disclosed in the accompanying drawings, wherein there are shown several preferred embodiments of this inventive concept.
In the drawings: Figure 1 is a side elevational view of one form of projectile constructed inl accordance with this l projectile, and Ymore Figure 6 is aside sectional View of a still further modified form of projectile.
v Figure 7 is a. sectional view taken substantially along the line 1-1 of Figure 6.
Figure 8 is a view partially in elevation and -partially in section disclosing a still further modiviied form ofthe construction.
' Figure 9 is a sectional view taken substantially along the line 9 9 of Figure 3.
1 'FigurelO isa'sectional View taken substan- -tial1yia1ongthe line IU-I of Figure 4, and :viewed in the.' direction indicated by the arrows, fan'd.
. Figure 1l isa sectional View taken substantially'along the line Il-I I of Figure 5, as viewed inthe direction indicated by the arrows.
1 Likeiireferencenumerals refer to like parts throughout the several views of the drawings.
Having reference nowto the drawings, and more particularly to Figures 1 to 3, inclusive, there is generally indicated at 20 a projectile 'comprised of. a hollow casing 2| which may have rifling rings' 22 integra1ly formed therewith. The casing 2|is adaptedto contain a propulsive chargezofcpowder '23, or the like. The rear end offthecasingis open` and is formed to provide alooped ilange' 24 which extends inwardly of the casing.. as at 25, interiorly of the fold 25 back ltoward the rear of the projectile, as at 26, the portion 26- forming a detonating anvil. The Vspaces within the folds formed by the flanges 24, 25,; and -26are lled with an explosive 21 comprising,adetonatingcharge. A powder ring of readily frangible material 28 is adapted to retain the propulsive:z charge until blown out by the detonation thereof.; ,Fromthe foregoing it will now be seen that :when a firing pin strikes the ring 24, the detonatingcharge 21 is struck against the anvil 26, which detonating charge res the main propulsive charge 23 of the projectile. Thus, the projectile is immediately. propelled forwardly in the ,barrel of the gun, or the like, the explosive charge continuing to burn and increase the propulsive eilectthereof after/the same has left the barrel; onemethod of loading the projectiles 20 illustrated in Figures 1, 2 and 3 inclusive, comprises the forcing of the detonating charge 21 into the folds formed by the flanges 24, 25 and 26 at the inner open end of the projectiles by suitable means, such as by blowing the charge into the interior of the projectiles while being held in a vertical position, the nozzles of the filling means forming substantially tight nts with the inner edges of the flanges 25. After the detonating sitioned in the extremity thereof a solid metal Y member 3| secured in position, as by a screw 32,
to form an armor-piercing projectile. The body portion of the shell back of the member` 3l is provided with a propulsive charge-*'33, and the rear end of the projectile is provided-with burned, whereupon the additional charge 82 will continue to impart propulsion to the shell long after the same has left the barrel of the gun.
Now, from the foregoing, it will be seen that there is herein provided an improved projectile accomplishing all the objects of this invention and others including many advantages of great practical utility and commercial importance.
many embodiments may be made of this invnti'vefconceph and as many modifications "may be made in the embodiment hereinbefore shown and described, it is to be understood that `Eall matter herein is to be interpreted merely as illustrative and not in a limiting sense,
I claim: -1. xIma/device of the character described, a hol- .lowshell open at'itsrear end, a propulsive powder arcuate portion 34 curving back upon itselfto form a projecting point 35 serving as an any-11,' the space between the annular rim formed by the anvil '35 beingclosedby an Aintegral plate-36 having an aperturel therethrough. In this v-modi- CatiOn, the ring pin is ladapted to strike' the ring 34 to explode the. idetonat'ing chargeM38 against the anvil 35,' which in turn ignites`-the propellant charge 33 Aandpropels the projectile in the manner previously discussed. 'With reference to Figure 5,-,a Esimilar `constructionis shown comprised of a'casing '40.having Ashrunk rifling rings IH thereon, and being Aprovided 'atits rear extremity with ,an interiorly positionedfannulus or groove '42 within which is Welded'or otherwise secured a flanged member 43 provided with an interiorly extending portion 44 forming a ring 45, and a reversely extendingfportion '46 providing an -anvilfll A powder-'ring 48'-closes the open space 'between the, interiory :periphery of the portion Llll,.anda compression. charge or detonating charge 49is adapted, whenithe 'ring sive charge 5B.
