 <EMI ID=2.1> 

  
d'améliorer l'étanchéité , l'imperméabilité et la résistance

  
des cartouches de chasse et d'éviter le gonflement, par temps humide .

  
Suivant l'invention le tube en carton de la douille est entouré par une enveloppe métallique (par exemple laiton ,

  
zinc , aluminium etc...) s'étendant: sur toute la hauteur de

  
la cartouche .

  
L'invention concerne aussi bien les cartouches de chasse

  
 <EMI ID=3.1> 

  
confection de ces cartouches .

  
Pour compléter la résistance des cartouches vers l'endroit de, la charge de poudre et pour éviter la compression de

  
la poudre sous l'action du sertissage , 1' invention prévoit

  
que la base de la douille est renforcée à l'intérieur par un

  
tube supplémentaire , métallique ou en carton , maintenu dans

  
le bourrage entourant l'amorce et s'étendant, sur la hauteur

  
de la charge de poudre de la cartouche .

  
Comme dans certains cas , l'humidité pourrait pénétrer

  
à l'intérieur de la cartouche le long des parois de l'amorçage ,  <EMI ID=4.1> 

  
rendant cet amorçage invisible . A cet effet , celui-ci est logé dans le fond de la douille et est recouvert par le culot extérieur . 

  
Dans ce cas l'amorce est retenue simplement, par l'enveloppe métallique renforçant le fond de la douille . La faible épaisseur de cette enveloppe nécessite des moyens pour compléter la résistance au déplacement: de l'amorce . Ces moyens sont constitués suivant 1\invention par une ou des gorges annulaires formées dans la, douille vers la base de celle-ci de façon à maintenir solidement le bourrage .

  
Suivant l'invention , l'enveloppe métallique spécifiée ci-dessus peut avantageusement. être constituée par une enveloppe en zinc.

  
Les dessins annexés indiquent à titre d'exemple non limitatif deux modes d'exécution de l'invention . Celle-ci s'étend aux diverses particularités originales que comportent les dispositions représentées .

  
La fig.l est une vue en coupa d'une cartouche suivant  un mode de réalisation de l'invention .

  
La fig.2 est une coupe dans un autre mode de réalisation de l'invention .

  
Dans le cas de la fig.l , le tube en carton 2 est entouré sur presque toute sa hauteur par une enveloppe métallique 3 en laiton , zinc, aluminium etc... La partie supérieure 2a du tube en carton sert au sertissage de la cartouche ainsi que montré en pointillés . La base de la

to improve waterproofing, waterproofing and resistance

  
of hunting cartridges and avoid swelling in wet weather.

  
According to the invention the cardboard tube of the sleeve is surrounded by a metal casing (for example brass,

  
zinc, aluminum etc ...) extending: over the entire height of

  
the cartridge .

  
The invention also relates to hunting cartridges

  
 <EMI ID = 3.1>

  
making these cartridges.

  
To complete the resistance of the cartridges towards the place of, the powder charge and to avoid the compression of

  
the powder under the action of crimping, the invention provides

  
that the base of the socket is reinforced on the inside by a

  
additional tube, metal or cardboard, held in

  
the stuffing surrounding the leader and extending upwards

  
the powder charge of the cartridge.

  
As in some cases, moisture could penetrate

  
inside the cartridge along the walls of the priming, <EMI ID = 4.1>

  
making this priming invisible. For this purpose, it is housed in the bottom of the socket and is covered by the outer base.

  
In this case the primer is simply retained by the metal casing reinforcing the bottom of the sleeve. The small thickness of this envelope requires means to complete the resistance to displacement: primer. These means are constituted according to the invention by one or more annular grooves formed in the sleeve towards the base thereof so as to securely hold the stuffing.

  
According to the invention, the metal casing specified above can advantageously. consist of a zinc casing.

  
The accompanying drawings show, by way of non-limiting example, two embodiments of the invention. This extends to the various original features contained in the provisions represented.

  
Fig.l is a sectional view of a cartridge according to one embodiment of the invention.

  
Fig.2 is a section through another embodiment of the invention.

  
In the case of fig.l, the cardboard tube 2 is surrounded over almost its entire height by a metal casing 3 made of brass, zinc, aluminum, etc. The upper part 2a of the cardboard tube is used for crimping the cartridge as shown in dotted lines. The basis of the

  
 <EMI ID = 5.1>

  
base 4 hold primer 5. An additional tube 6,

Claims

metal or cardboard, is suitable for the interior of the

cartridge to be flush with the normal level of the

powder. A padding 7 is provided to reinforce the bottom of the

socket and hold the primer securely in the base of the

cartridge.

The cartridge is loaded in <EMI ID = 6.1>

in 9 a cardboard washer, in 10 a fatty wad, in.

11 an elastic filling, for example felt, in 12 the

lead charge. The cartridge is closed.

by a cardboard washer 13 which is covered with varnish

to ensure waterproofing.

In the case of f ig. 2, the 5- primer is, engaged in

the base of the metal casing 3 while the base 4 of

the socket covers this primer so as to make it invisible.

Keeping the primer firmly in the base of the

socket is obtained by the fact that annular depressions

so as to oppose any movement, of it during

percussion.

The invention is not limited to the embodiments

described by way of example, but it also extends to any

casing or hunting cartridge entering- in the spirit or in

the scope of one or more of the following claims.

CLAIMS.
