FR2788338A1 - Loading system for firearm with separate loading of cap, powder and ball uses recess designed to receive percussion cap with inner striker plate - Google Patents

Abstract

The system uses a recess (1) located adjacent to the end the firearm barrel (4) and designed to receive a percussion cap (2) with an inner striker plate and linked to the barrel by a channel (3). The recess can be made in a separate component fitted to the end of the barrel by a screw thread and positioned either in line with the barrel or at an oblique angle to it.

Description

The present invention relates to a device for ensuring the

  fire on firing weapons with fractional loading, called "black powder" or "A loading rnr the mouth", or even "with piston", but also "cap & ball", and of this fact not using cartridge . Firing on these weapons is traditionally ensured by means of a capsule placed on a chimney. However the capsules which cover the chimneys hold badly and make projections outside; de m'me the chimneys receive the shock of the dog, and they must be changed after a certain use, but the diversity of these makes the supply

sometimes difficult.

  The device according to the invention overcomes these

  disadvantages. It has in fact according to a first characteristic

  ristic, instead of the chimney (s), flax (or>) bowl-shaped housing intended to no longer receive a piston rifle capsule, but a cartridge primer of known type, with internal anvil, such as boxer caps or

  closed caps of hunting cartridges; this nlogeme, t communi-

  as in a conventional way by a channel, or lumiJre, with the cham-

  bre of the barrel block, or of the barrel, in order to transmit until there To the flame and the breath. This device makes it possible to limit any risk of projection of the primer outside, because it is then belted, but also to use primers which are easy to supply, which are less likely to fall from the weapon; while eliminating the problems of matting of the chimneys thanks to the presence of an internal anvil, in soft metal, and serving only one, faith. All the rest of the weapon being arranged in a conventional manner, and the firing being made by a striker in

protrusion.

  According to particular embodiments: - the housing of the primer can be arranged directly on the barrel block, the barrel, or other, which I] mite l1 number of parts. - the housing of the primer can be placed in a separate part, carcass for example, in order to allow loading by

  the back, like on the forced bullet pistols, for example.

  - the primer housing can be placed on a dentine piece: e

replaces existing chimneys.

  - the axis of the housing and / or of the light can possibly

  form an angle with the axis of the barrel.

  - the housing of the primer can be in direct connection with the barrel, without channel or light, provided that this barrel is of a diameter less than that of the primers used, which in this case are positioned on a flange, all thus allowing rear chrIrgement, and the firing of small projectiles

without adding powder.

  - the housing of the primer can very well be combined with a fake cannon, cut for example, on alarm weapons, choke or shotgun, instead of the current weapons using blank cartridges and posing risks of transformation.

  The accompanying drawings illustrate the inventi-n.

  Figure 1 shows in section the device of the invention.

  FIG. 2 represents in section a variant, with a barrel which can be loaded from the rear, here with a unscrewable barrel,

  such as forced bullet pistols.

  Figure 3 shows in section another variant allowing

  replace conventional fireplaces.

  Figure 4 shows in section a variant with the axis of the box-

  ment and channel, forming an angle with the axis of the barrel.

  Figure 5 shows in section several possible variants, with a housing for a closed primer; a small caliber cannon in direct connection, without channel or light, allowing rear loading; as well as a barrel which can be shrunk in a softer material. Each element can be

  present independently of others.

  Figure 6 always shows in section a variant with a fake cannon of more or less scalloped shape for weapons

  alarm, choke or rocket launcher.

  With reference to these drawings, the device comprises a barrel block, or barrel, one of the faces of which, rear or lateral, is provided with a housing (1) for a primer (2) given, with a channel or light (3) to transmit the ignition, the breath, or the noise, in the chamber of the barrel block, the barrel, (4+), or the false barrel (5). The striker, not repr / snt, is

always protruding.

  Note also that in other v.riantes not shown - the housing of the primer can be placed on a screw cap, allowing to obstruct the back of the room, but also

facilitate cleaning.

  - the primer housing can be placed on a movable breech block, obstructing the rear of the barrel, while allowing

rear loading.

  - the housing of the primer can be placed both in the back and in dan. the axis of the barrel, or offset; that on the side, (lde

  perpendicular or inclined.

  The dimensions of the housing (1) of the chosen primer are such that they allow easy installation and removal, while limiting the risk of falls or (projections. A liter of non-limiting example, the housing of the primer will have an internal diameter of pl's or less 5.5 mm and a depth of the order of 3 to 8 mm, possibly with a shoulder and a connection cone depending on whether a particular type is used The diameter of the channel, or lumen,

being about 1.5 mm.

  The device according to the invention is compatible with

  various known systems intended to prevent any transformation

  -100O mation to use cartridges.

  The device according to the invention is particularly intended for firearms with split loading, that is to say

not using cartridges.
