Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a keyed closure machine (Keilverschlus).
s) and the impact bottom of the keyed closure by a predetermined distance from the firing hole during the piercing of the cartridge, which is slidably supported within the keyed closure.
The present invention relates to a device for igniting a firearm cartridge, which includes a spring-loaded ignition pin for piercing the cartridge.

In the case of a known device of this type (German Patent No. 1 149 276), two axially movable abutments of the firing pedestal are used for repeating span pullers for firearms, in particular for artillery. The loading and firing spring between them is biased. These abutments are controlled by Tafu.

The Tafu rotation shaft supports twin cams, which are two cams facing each other, and extends horizontally to the firing shaft. During tensioning, one of the two cams acts via a pressure member on the rear spring abutment, while the other cam controls the amount of tension and the tensioning member rigidly connected to the firing pedestal. Acts on the front spring abutment via the sleeve.

However, this device has the following drawbacks. That is, a reliable piercing of the cartridge through the firing stock or ignition pin is simply a matter of ensuring that the cartridge present in the gun barrel (with the sleeve bottom with the internally piercing primer) is free of gaps and locks in the keyed closure mechanism. This is only guaranteed when the impact base is in close contact with the cartridge, i.e. the firing barrel hits the cartridge through the tension spring, and its shoulder then hits the stop in the key-shaped closure. As long as the tip of the pin always protrudes the same amount through the bottom of the shock of the keyed closure, and the bottom of the sleeve of the cartridge is close to the bottom of the shock of the keyed closure, the tip of the firing barrel will always project to the same depth. This is because if the tip of the firing stem goes deep into the detonator, there is an unavoidable danger that the bottom of the detonator will penetrate. This is not allowed, because otherwise the fuel gas can reach the weapon through the perforated detonator, causing damage.

However, the extractor-groove (Au5zieher-Ri
When inserting the cartridge into the cartridge bearing of the gun barrel, the cartridge sleeve is not necessarily struck equally hard. Therefore, the bottom of the sleeve of the cannonball, which is oriented in the axial direction of the gun barrel, is not always in the same position, but on the contrary, during heavy strikes of the cannonball, it is significantly forward. The cartridge, on the other hand, will have a projecting edge. The cartridge always extends far into the barrel until its edge is close to the rear end of the barrel. However, since the key-shaped closure of the firearm is not slidable in the axial direction of the gun barrel, during a violent strike of the cartridge sleeve, the bottom of the sleeve no longer fits tightly against the impact base of the key-shaped closure without a protruding edge. However, if the bottom of the sleeve is no longer in close contact with the impact bottom of the keyed closure, it is no longer guaranteed to reliably pierce the detonator of the cartridge, since the percussion stem cannot penetrate deep enough into the detonator bottom. Become.

The problem to be solved by the invention is to provide an ignition device which guarantees a reliable thrusting of the cartridge independently of the impact of striking the cartridge sleeve during insertion into the gun barrel.

The device according to the invention which solves this problem is characterized by a slidable, ignition bulge projection which can be resiliently supported on this object at the impact bottom of the key-shaped closure.

In particular, the slidable object is designed as a large-bore plug that is slidably fixed on the key-shaped closing device through a bayonet joint.

A particularly advantageous embodiment of the device for igniting a cartridge according to the invention in a firearm with a key-shaped closure will be explained in detail below with reference to the drawings.

In FIG. 1, the igniter of the present invention is located within a keyed closure 10 of a firearm (not shown). The ignition device has an ignition pin or firing pedestal 12 which is fixed in a sleeve 13 which is slidable into the hole 1 of the keyed closure 10. This through hole 11 has sections 14 to 15 at both ends.
It is blocked by. The spring 16, which is partially inside the sleeve 13, is on the one hand at the bottom of the sleeve 13;
On the other hand, supported by piece 15, the ignition pin 12 can be pushed into the hole 17 (FIG. 2) of piece I4, shown as a large hole insert.

In order to move the ignition pin 12 from the position of FIG. 1 against the force of the spring 16, ie to slide it to the right in FIG. 1, a cam disc 18 fixed to the shaft 29 is used. The cam disk 18 has a cam 1 supported on the shoulder 20 of the sleeve 13.
It has 9. To block the ignition pin 12,
A port 21 is used which is slidable on the shaft. The bolt 2

3 into a recess 22. Both parts 14, 15 are fixed in the bore II of the keyed closure 1o with a conventional bayonet joint. The shape of the piece 14 is 2nd to 5th.
It is clear in the figure.

In Figures 2 to 5, the piece 14 has a cartridge sleeve 25 (first
It has a plate 23 that is tightly attached to the bottom 24 (see figure), and has two cams 26 and 27 on the rear side. The cam prevents the projecting piece +71 from engaging and disengaging from the hole 11 of the key-shaped closure 10 into the corresponding recess in the hole 11. In order not to pull the piece 14 out of the hole 11, the piece 14 has to be rotated through 90° in this hole, and for this purpose two slots 28 are opened in front in the disk 23. There is. The piece 14 is held by a bayonet joint in the bore 11 of the keyed closure 10 for a limited axially slidable stroke. In the state shown in FIG. 1, the sleeve 13 of the ignition pin 12 is supported by the piece 14, and the spring I6 moves the piece 14 through the sleeve 13 to the bottom 24 of the cartridge sleeve 25.
as a result of which the disk 23 is pressed against the sleeve bottom 24
closely adhere to. The tip of the ignition pin 12 protrudes from the plate 23 by a predetermined amount, and when the feeder cartridge 25 is pierced, it enters the detonator (not shown) of the IJ cartridge 25 exactly at this value.

The mode of action of the described ignition device is as follows.

In order for the cartridge 25 to be pushed into the barrel of the firearm, the keyed closure mechanism 0 must be slid downward in the direction of the arrow (Fig. 1) and as soon as the cartridge is in the barrel, the keyed closure mechanism 10 reaches the closed position again. During insertion of the cartridge into the gun barrel, the cartridge sleeve 25 is struck more or less forcefully. As a result, the distance a between the sleeve bottom 24 and the so-called impact bottom 30 of the key closure 10 is not always of the same magnitude. However, since the piece 14 is arranged to be axially slidable in the bore 11 of the key-shaped obturator IO, the spring 16 is able to move the piece 14, and thus the borehole insert, through the sleeve 13 into the cartridge. Press against the bottom 24 of the sleeve. This occurs when the port 21, which projects into the recess 22 of the sleeve 13, releases the sleeve 13 and the ignition pin 2 for the purpose of piercing the cartridge. After the bullet pierces, the ignition device fires again!・To be done. For this purpose, the cam disk I8 is rotated clockwise by the axis of rotation 29, in which case the cam 19 hits the shoulder 20 and, against the force of the spring 16, moves the sleeve 13 together with the ignition pin 12 again to the right in FIG. push towards

Since the point of the ignition pin 12 can only protrude from the piece 14 by a predetermined amount, the ignition cap of the cartridge always remains at the same depth, regardless of the forceful tapping of the cartridge sleeve during insertion into the gun barrel. I get stabbed by it.
