Abstract

Novel projectile with high initial speed, at low cost price, constructed from zinc or a zinc alloy, and whose method of manufacturing is casting.

Description

la présente invention concerne un projectile pour ârnltà feu de poing ou d'épaule à canon lisse ou rayé. the present invention relates to a projectile for arnltà hand or shoulder fire with a smooth or rifled barrel.

Le but de cette invention est de réaliser un projectile de frange vitesse initiale à un prix de revient réduit d'une part grâce au matériau utilise et d'autre part grâce au mode de fabrication adopté. The object of this invention is to produce an initial speed fringe projectile at a reduced cost price on the one hand thanks to the material used and on the other hand thanks to the manufacturing method adopted.

L'emploi de ce projectile est analogue aux projectiles conventionnels (tir à la cible,chasse,défense,etc, ...). The use of this projectile is analogous to conventional projectiles (target shooting, hunting, defense, etc.).

En l'étant de la technique les projectiles pour armes de poing ou d'epaule sont constitues de cuivre ou d'alliage de cuivre (laiton) et sont obtenus par tournage. Un autre procédé classique consiste à chemiser à l'aide d'une enveloppe de cuivre ou d'alliage cuivreux (maille chor t, tombac,etc,...) un noyau de plomb matrice ou un noyau d'acier tourné. By being technical the projectiles for handguns or long guns are made of copper or copper alloy (brass) and are obtained by turning. Another conventional method consists in lining with a copper or copper alloy casing (chor t mesh, tombac, etc.) a matrix lead core or a turned steel core.

Le nouveau projectile est caractérisé par le fait qu'il est constitué d'une piece monobloc de zinc ou alliage de zinc. The new projectile is characterized by the fact that it consists of a one-piece piece of zinc or zinc alloy.

La proportion de zinc contenu dans cet alliage est égale ou superieure à 60Z de sa composition. The proportion of zinc contained in this alloy is equal to or greater than 60Z of its composition.

Le mode de fabrication employé pour ce projectile est le coulage rendu possible par le faible point de fusion de matériau (4200C).T out autre procédé peut-être néanmoins appliqué. The manufacturing method used for this projectile is casting made possible by the low melting point of material (4200C). Any other process can nevertheless be applied.

Ce projectile en zinc ou à trés forte teneur en zinc obtenu par coulage se distingue donc des projectiles connus à ce jour dans le commerce. This zinc projectile or a very high zinc content obtained by casting therefore differs from projectiles known to date in the trade.

Les caractéristiques de forme restent traditionnelles;ogivale conique,plate,etc,.. ainsi que les moyens de lubrification permettant d'améliorer le glissement du projectile dans le canon de 1 'ar- me (gorge de graissage, pellicule,etc,...).  The shape characteristics remain traditional: conical, flat, etc., as well as the lubrication means making it possible to improve the sliding of the projectile in the barrel of the weapon (lubricating groove, film, etc.). .).

Claims (3)

REVENDICATIONS I) Projectile de grande vitesse initiale pour armes de poing ou d'épaule caractérisé par le fait qu'il est constitué par une piece monobloc homogene en zinc ou alliage de zinc dans des proportions supérieure ou égale à 60% de sa masse totale.I) Initial high speed projectile for handguns or long guns characterized in that it is constituted by a homogeneous monobloc piece of zinc or zinc alloy in proportions greater than or equal to 60% of its total mass. 2) Projectile selon la revendication n I caractérisé par le fait qu'il est obtenu par coulage.2) Projectile according to claim n I characterized in that it is obtained by casting. 3) Projectile selon les precedentes revendicatjons comportant un moyen de lubrification propre à améliorer son glissement dans le canon de l'arme. 3) Projectile according to the preceding claims, comprising a lubrication means suitable for improving its sliding in the barrel of the weapon.
