UNITED STATES PATENT oFFroE.
CHARLES r. WATSON, or rrrrsnnne, PENNS'YLVANIA.
To all whom it may concern:
Be it known that I, CHARLES I. WVATsoN, a citizen of the United States,,residing at Pittsburg, State of Pennsylvania, have invented new and useful Improvements in Projectiles, of
which the following is a sp ification. My invention relates to bullets or proto those emto produce a soft metal bullet with a jacket of novel construction; to produce a mushrooming or expanding bullet of novel construction; and to provide a'bullet or projectile with a packing ring or gas check of novel construction at its rear end.
' The several improvements constituting my invention may all be embodied in one and thesame bullet or projectile, and this is the preferred construction, although they are capable of separate, as well as joint, use.
I am aware that projectiles for small arms have been provided with smooth, hardinetal jackets, and with wound jackets formed of fibrous coated wire laid in. exterior circumferential grooves formed in the metal of the body of the projectile. There are certain well recognized objections to a bullet or projectile for small arms provided,
with a smooth hard-metal jacket. The wire and fabric wound'bullets are also open to serious objection, especially when attempt has been made to use them with smokeless or other powder producing very high ve- I the bullet shown in Fig. 1. Fig. 3 is a transverse section thereof. Fig. 4 is an elevation of abullet different from that shown 1n Fig.
- 1, embodying some of the features of my invention, part of the nose of the bullet be-. ing broken away. Fig. 5 is a long tudinal sectional view-of a bullet difierent from that shown in any of the other views, embodying in the county of Allegheny and Specification of Letters Patent. Patented Sept. 26., 1911. Application filed Janualy lB, 1910. Serial No. 537,901.
view of the coil of wire adapted to consti-- wthe body A, but of less specific gravity, with a hard-metal jacket C formed of coiled wire.
exteriorly surrounding the body, and a packing rmg or gas check D at the rear end of the bullet.
close coil of hard-metal wire, German silver The jacket is formed of a for instance, the ends a of which are carried within the coil andleft free and exposed. This jacket is incorporated into the bullet when the body A thereof is cast, that is to say, a coil like that represented in Fig. 6 is introduced into the bullet mold before the metal of the body is poured therein. The result is that the metal flows into the grooves between the convolutions of the wire, and embeds the ends 0 thereof so that so intimate a'union between the jacket and the body A is secured that it is impossible to separate one from the other without devstroylng the integrity of the bullet.
A jacket such. as described will carry thelubricantrequired for a bullet or projectile of this nature, and prevents the metal of the body from contact with the gun barrel and takes well to the rifling. I
'In casting the bullet shown in Fig. l the rearend of the body is formed with a. shoulder cl which provides a seat for an annular split ring D which constitutes a packing or gas check. The ring D is applied to its seat after the bullet has been formed and preferably while the bullet is inthe 'shap- I ing and sizing die, at whichwvtime the rear end of thebullet is sufficiently expanded .against the ring to securely hold it in place,
or it may be cast on.
The featuresof the invention thus far described are applicable to a soft or hard nose bullet. I have, however, shownit as applied to bullets embodyinganother fea ture of my,invention which consists of a separate nose piece of metal harder than the body A- but of less specific gravlty. I prefer to use aluminum or an alloy'for such nose piece. The use of the hard nose piece 13 causes an expanding or mushrooming having a bullet mold, thus enabling a user of the bullet when it strikes. The nose piece being of much less specifi'c gravity than the rest of the bullet has correspondingly less inertia and hence its motion is more quickly retarded upon striking an object than is the rest of the bullet, with the resultthat the body is instantly and violently expanded. The shape of the hard nose piece may be changed to suit different conditions. For instance in Figs. 4 and 5 a spherical form of nosepiece designated B is shown.
In Fig. l is shown a form of nose piece designated B, so shaped as to constitute the entire nose of the bullet. It is provided with a shoulder 6 back of which extends an ovoid portion or neck of reduced size I) that is embedded in the body of the projectile. That portion of the nose piece that is embedded within the body A. is corrugated grooved or roughened so as to secure a close and intimate engagement between these two parts, while the exposed part of the nose piece is preferably smooth. The form of nose piece shown in Fig. 1 is especially advantageous if used in bullets thathave to be forced into place within the gun barrel especially of an automatic arm and which, when made entirely of soft metal, are liable to have their forward or nose ends deformed from this or other causes, which may ,clog the arm and destroy accuracy of projectile when fired.
' It is evident that a jacketed bullet such as I have described can be made by any one of firearms to easily make his own jacketed projectiles, which is sometimes a matter of great convenience and importance. I believe that I am the first to have produced a jacketed soft metal bullet that can be thus easily and successfully made Without the necessity of expensive and complicated apparatus.
\Vhat I claim is L 1. A projectile having a metal body and a metal jacket harder than the body and formed of a close coilof wire surrounding the body and intimately united thereto by the casting thereof.
2. A projectile consisting of a metal body and a'hard metal jacket formed of a close coil of wire, the ends of the latter being em bedded Within the body.
- 3. A projectile consisting ofa metal body and a jacket fitting about the body and formed of closely coiled wire, the ends of which are carried Within the convolutions of the wire and left free, the metal of the body being cast about such ends of the wire.
4. A bullet or projectile formed of soft metal having a shouldered seat at its rear end, and 'a hard-metal split ring upon the said seat, the metal of the body being expanded to hold the ring upon its seat, substantially as set forth. r
