Be it known that I, EMIL GATHMANN, a citizenof the United States, residing at South Bethlehennin the county of Northampton and Stateof Pennsylvaniahave invented certain new and useful Improvements in Projectiles, of which the following is a specification.

My invention relates to that class of projectiles provided. with soft-metal caps; andit consistsin the means of securing and retaining the said-caps in place upon the projectiles, as fully set forth hereinafter and as illustrated in the accompanying drawings, in which- Figure 1 is a side view of a projectile with the cap in cross-section thereon, showing the improved retaining means. Fig. 2 is the same, showing the form 4of the cap before it is secured and the die for securing the same. Fig. v3 is a detached view'of the retainer, and Fig. 4

-is a'detachedwsectional view showing the form of the cap before it is secured inplace.

sTheprojectile is of any suitable construction, with a `body portion A and a pointed end which, as shown, is conoidal, and adjacent to the said end is an annular recess 1, extending' 'circumferentially and of asuitable cross-section to coincide with the cross-sectional form of a retainer C, the latter being in theform o t' a divided-ring, the inner portion of which lits the said recess. -The soft-metal point B has arsocket adapted to receivethe Apointed end of the projectile and has'alsoan annular recess of a form corresponding to the project- .mg portion of the retaining-ring C, the cap extending back beyond the said ringand f1ttingelose against the surface of the projectile, as shown m Fig; 1, wherebythesaid ring serves asa means of securely retaining the cap upon the point of the projectile.

In the application of the-cap to theprojectile the cap is rst formed with a socket and an annular enlargement, Fig. 4, of such internal dimensions that it will. pass readily over the retaining-ring and externally greater in diameter than the body of the. cap. The parts are put 1n position, Fig.l2, and the cap is'then passed through the opening of a die D and, together with the projectile, is carried onward until the action of the die serves tom Il m-n-rrd compress the enlargement of the cap., bringing it to the same diameter as the remaining portion of the cap and extending and spreading the projection 3 over and around the retaining-ring and onto the face of the projectile.

Preferably the retainer is of hard metalas, for instance, hard steelso that the annular projection or 'lip of the cap will readily liow over the same during the passage of the cap through the die. Further, the ring is preferably split, so that it can be expanded to pass it over thepoint of the projectile and .into the groove or recess and will then contract, so as to fit closely the said groove.

When the cap is applied, it wholly incloses the ring and holds the ends together, so that they cannot separate and permit the cap to become loose.

It will be evident that the ring may be of any suitable cross-sectional form, the grooves in the projectile and cap corresponding thereto, and that it may be made of any desired material.

Without limiting myself to the construction and arrangement shown, I claim- 1. A projectile having a pointed end, combined with a soft-metalv cap having a socket receivingsaid end, and with an annular retainer fitting an annular groove in the projectile and corresponding groove in the cap and wholly-inclosed by the latter, substantially as set forth.

2. A'projectile having a pointed end combined witha soft-metal cap having a socket* receiving vsaid end, and with an annular retainerof harder material than the projectile,

fitting an annular groove in the projectile and corresponding groove in the cap and wholly inclosed by thelatter, substantially as set forth.

3. A projectile having a pointed end and annulargroove adjacent tothe end, combined with a cap of soft metal having a socket receiving the end of the projectile, and an annular groove coinciding with that of the projectile, and a retainer consisting of a split ring fittingand inclosed in said grooves, substantially as set forth.

4. A projectile having a pointed end and annular groove adjacent to the end combined with a cap of softl metal having a'soeket re- Iutestimonywhereof Ihave signed my name ceiving the end'of .the projectile and an antao this specification in the presence of two subnular groove coinciding with that of the pro-V scribing Witnesses. v, jectile, and a retainer .consisting ot' a split; ring EMIL GATHMANN. of harder metal than the projectile fitting and Witnesses:

inolosed in said grooves, substantially as set WVM. S. HERMANY,

forth. LEIGHTON N. D. MIXSELL.
