rRoJEcTrLE.

Specification of Letters Patent.

, Patented Dec. 17, i918.

Application filed August 26, 1918. Serial No. 251,522.

To all 'whom it may concern Be it known that we, JACOB KUHN and JOHN A. GUiLER, citizens of the United States, and residents of Connellsville, in the 'county of Fayette and `State of Pennsyl- .gun barrel through .which the Aprojectile is forced.

More specifically, the invention comprehends the provision of a projectile provided with a pluralityv of` circumferentially spaced longitudinally vextending ribs or strips, de-

tachablyca'rried by the body of the prov jecti'le and formed of a relatively. soft metal, which may be grip'p'ed or will blte into the rifle of the gun barrel, without cutting the rifling of the gun barrel.

Other objectsof the invention will appear in the following detailed description, taken in connection with the accompanying drawing, forming apart of this specification, and in which drawlng:

Figure 1 is a sideelevation of a projectile constructed in accordance with this invention. Y

Fig. 2 is a fragmentary longitudinal section throughthe projectile.

Fig. 3 isa transverse section taken on the line 3-'3'of Fig. 1.

Referring more particularly to the drawl ing, 1 indicates the projectile, which may be a shrapnel shell, rifle bullet, solid projectile,

4or any of the many types now in use. The

projectile 1 provided witlra plurality of circumferentially spaced longitudinally extending dovetail recesses 2, the forward ends of ,whichterminate in substantially circularv recesses. 3 near 'the nose or pointed end of the projectile. Strips 3 of soft metal, such as copper or the like, are inserted in the recesses 2, the said strips being dove-tail in cross section for fitting snugly within the reoesses so as to prevent the strips frownspringing therefrom and these strips 3 have plugs 4 formed upon their forward ends which fit in the substantially circular recesses 3. The recesses `2 communicate with jectile through a the butt end. of the projectile, and in assembling the same, the strips 3 of the relatively soft metal are drivennwardly from the butt ends of the rojectile, and when they are completely riven therein, their forward ends are upset Vand hammered into the recesses 3', to 4-prevent. longitudinal movement of the stripsduring the passage of the proun barrel.

Changes in details may be made withou lparting from the spirit of this invention,

nt; We claim:

1. A projectile provided with a plurality of longitudinally extending dove tailed grooves, and strips of relatively soft metal in said grooves and projecting beyond the periphery of the projectile.

2. A projectile provided with a plurality of circumferentially space longitudinally eX- tending grooves, strips of relatively soft metal mounted in said grooves and projecting beyond the outer surface of the projectle, and means to preventmovement of said strips within said grooves.

3. A projectile provided witha plurality of longitudinally extending' dove-tailed `grooves, strips of relatively soft*E metal mounted in said grooves and projecting beyond the outer surface of the projectile, and means to prevent longitudinal movement of said strips independent of said projectile.

4. A projectile provided with a plurality of longitudinally extending dove-tailedgrooves'opening at the butt end of the projectile and terminatin in sockets near the nose end of the project1le, strips of relatively soft metal positioned insaid grooves and projecting beyond the outer surface of the projectile, said strips having their forward ends upset and hammered into said sockets to prevent longitudinal .movement of the stripswith respect to the projectile.

5. A projectile provided with a plurality of longitudinally extendin grooves opening outat the butt end of t e rojectile and terminating in the nose thereof metal strips positioned in said grooves and means to prevent the movement of the strips independently of the projectile.
