US Patent:

20020178963, Dec 5, 2002

Filed:

Nov 9, 2001

Appl. No.:

10/010009

Inventors:

Henry Halverson - Collinsville IL, US

Assignee:

Olin Corporation, a corporation of the State of Virginia

International Classification:

F42B012/00
F42B010/00
F42B030/00

US Classification:

102/516000

Abstract:

A jacket precursor, a pellet first core precursor, and a second core precursor are provided. The pellet and second core precursor are inserted into the jacket precursor. The second core precursor is pressed against the pellet so as to deform the pellet to fill a frontal volume of the jacket precursor as a first core with relatively less (if any) deformation of the second core precursor. An aft portion of the jacket precursor is deformed to contain the second core precursor as a second core. Preferred embodiments are formed substantially as drop-in replacements for existing bullets. A match embodiment features a lead rear core and a very light front core (e.g., a carbonate powder). A non-toxic embodiment comprises a tin front core and a harder rear core.

Appl. No.:

9/067580

Inventors:

Henry J. Halverson - Collinsville IL

Assignee:

Olin Corporation - East Alton IL

International Classification:

F42B 1202
F42B 1234

US Classification:

102501

Abstract:

A projectile having improved accuracy when fired over long ranges is formed from a monolithic block of a copper alloy. Proceeding from a nose to a heel of the projectile, is a fore portion with arcuate side walls, a body portion of substantially constant cross-sectional area that minimally contacts a rifled gun barrel, a drive band having a diameter effective to seal propellant gases and an aft portion that continuously decreases in diameter terminating at the heel. A cylindrical bore extends from an opened end at the nose to a closed end proximate to a transition plane between the fore portion and the body portion.

Assignee:

Olin Corporation - Stamford CT

International Classification:

F42B 1316

US Classification:

102520

Abstract:

A high velocity traced armor penetrating subcaliber projectile core having sealed radial spin-up notches on its base is disclosed. Also disclosed, is a plastic sabot for launching a traced subcaliber high velocity armor penetrating projectile core, which sabot is a cup shaped plastic body with a sealed passageway through its base and longitudinal weakening slots on the inside of its walls, the slot extending only part way down the inner surface of the wall to leave a cylindrical sealing surface adjacent the sabot base, whereby to provide a waterproof seal surrounding the rearend of the core and the tracer charge.

Appl. No.:

6/585327

Inventors:

Henry J. Halverson - Collinsville IL

Assignee:

Olin Corporation - Stamford CT

International Classification:

F42B 1316

US Classification:

102520

Abstract:

A high velocity ammunition sabot of brittle material which has sufficient strength to withstand the forces of being launched from a rifled gun barrel but which fragments almost immediately upon exit from the barrel due to centrifugal forces. A polyetherimide material is preferred, although materials of equivalent properties could be used.

Assignee:

Olin Corporation - East Alton IL

International Classification:

F42B 100
F42B 814

US Classification:

102517

Abstract:

A lead free ferromagnetic article is disclosed. The article is a compacted composite having a heavy more dense constituent that is preferably ferrotungsten and a less dense second constituent that is either a metal alloy or a polymer. The ferromagnetic constituent is present in an amount sufficient to impart the article with ferromagnetism. The ferromagnetic property allows fragments of the article, such as a projectile, bullet or shaped charge liner to be separated from dirt or other environments.

Appl. No.:

5/877939

Inventors:

Henry J. Halverson - Collinsville IL

Assignee:

Olin Corporation - New Haven CT

International Classification:

F42B 1110

US Classification:

102 91

Abstract:

A projectile for a centerfire cartridge achieves maximum energy transfer with limited target penetration. A hollow point lead bullet is provided with an aluminum jacket which allows the cartridge containing the projectile to feed reliably in auto-loading pistols and yet does not restrict normal expansion of the bullet upon impact with the target. The jacket extends into the nose recess of the bullet and covers the peripheral portion of the bullet base, whereby the jacket is securely fastened to the bullet and separation subsequent to impact is prevented. A method of fabricating the projectile is also disclosed.
