SPE FIOA'IION forming part of Letters Patent No. 269,101, dated December 12, 1882.
licaticn filed July 19, 1882.
To all whom it may concern:
Be it known that'I, James L. NORRIS, a citizen of the United States, residing at Washington, in the District of Columbia, am in possession of an invention for a new and useful Improvement in Projectiles for Ordnance, in=i vented by WILLIAM PALLISER, of which the. following is a specification.
This invention relates to projectiles for ordnance, whether of cast-iron or of steel, so conpenetration ot'armor plates, although they may be used for other artillery purposes. The body of the projectile is cylindrical, smaller than the bore of the gun. Its head extends in the form of a long-pointed conoid, the conoidal part being cast with a number of longitudinal ribs, by preference of triangular form, projecting from its surface. At the base of the ribs, which is at the springing otthe conoidal curvature, the diameter, measured across from point equal to that of the bore of the gun. On the cylindrical body, close up against the ends of the ribs, I shrink a metal ring or short jacket, having an external diameter nearly equal to that oi the bore of the gun. I also shrink or screw on a ring of like external diameter on diameter to receive it. This latter ring is turned down smaller for part or its Iength and has a screw cut on the reduced part. On this is screwed a ring of copper or other compara: tively soft metal, having a deep groove cut in its face. When the projectile is in the gun it rests evenly on the two rings, the one at each end of its cylindrical body, and when the chargeis fired the pressure of the powder-gas, acting in the groove of the soft-metal ring, ex pands it outward, so that it acts as a gascheck and takes the rifling, The head may be chill-cast in one piece with tho-bodyof the projectile, according to the well-known process invented by the said WILLIAM PALLISER; or the head maybe made of a. separate piece and fixed to the body. Its sharp conoidal form gives great penetrating power, the angular ribs on it having the 'efi'ect of initiating cracks ausing it to star in its fracture. The projecti e may be cast solid, or it may be cast with an internal cavity to re- Figure 1 of the accompanying drawings is on, and behind it a ring,
(No model.) Patented in England August 4, 1880, No. 3,191.
a longitudinal section of a the invention, the head in elevation; and Fig. 2 is a plan of the head, which is cast with longitudinal chiseledged ribs A for the purpose' mentioned above, the extreme diameter from edge to edge of these ribs being .a little less than the bore of the gun. Behind the ribs a wrought-iron or steel ring, B, is shrunk on, the exterior part of this ring nearly fitting the bore of the gun. It is preferably rounded off in front, as shown, so as to encounter less resistance of the air. At the base of the shell another ng, .O, is shrunk l), of copper or other sol't metal, is screwed on thebasefloijthe shell at its reduced part. This sot't-m-etali -ring is made with a deep groove, so that thepre'ssure, oi the powder-gas may to operate as a gas-check.
Instead of screwing on the gas-check ring D, as shown, it may be merely driven tightly on the boss at the base of the projectilewhich may be slightly undercut or have one or more shell according to portion bein g showin the powder-gas, forcing the ring inward as well as outward, will cause it to engage firmly 0n firing. The projectile may be made as a shell to receive a. bursting-cl1arge,'as shown, or it may be cast as a solid shot. In either case it is preferred that the head portion with its ribs be chill-cast if of castiroh.
Having thus described the nature of this invention and in what manner the same is to be performed, I claim-- The iniproved'projectile herein described, consisting of the conoidal head having the ribs A and a cylindrical body, the wroughtiron or steel ring B, shrnnk on the cylindrical body at the base of the ribs and conoidal head, the wrought-iron or steel ring O, shrunk on the rear end of the body, and the soft-metal ring I), secured to the latter against the rear ring, substantially as set forth.
In testimc "WhereofI have signed my name to this specification before two subscribing wit nesses.
