The UeueruBg concerns a closure isit extractor for Firearms, in which the one lying in a recess of the bolt head parallel to the bolt axis and for the overlap of the tape at the bottom of a cartridge in the chamber Extractor provided with an extractor claw has a pin at its rear end remote from the extractor claw engages in a radial bore provided in the closure, wherein at this rear end engages a movable bolt in an axially parallel bore of the closure, which bolt from a The compression spring is spring-loaded in the direction of the extractor.

It is well known that the extractor has the task of removing the empty cartridge case after the shot when the slide slides back of the cartridge chamber of the barrel head.

In a known lock design of an automatiscbeo Firearm, the extractor is located in an axially directed, elongated recess in the bolt head Rear closure forms a radial bore. This boh-

the bore and the pin are soon worn away by the jerky movements of the breech block and extractor and due to the additional stresses caused by cartridge cases tearing open every now and then. It then happens that the extractor falls out of the bolt head and the weapon becomes inoperable.

In another exemplary embodiment of the innovation, the extractor is allowed to strike directly against the inner wall of the sleeve. For this, it is only necessary that the extractor has a slightly elevated or cambered stoop or that a stoop inwardly directed stop cam is attached to the sleeve.

Further details, advantages and features emerge from the following description. In the drawing -different ones Embodiments of the innovation for example explained, namely show

Fig. 4 shows a detail of Fig. 3 in a modified version *

Fig. 1 shows a closure 1 which can slide in a sleeve 2 Mn-: and. The lock is pressed against the rear end of the barrel, the barrel head 3, by a closing spring (not shown). In the lock head 4 an elongated recess 5 lying parallel to the axis of the lock 1 is provided! The recess 5 ends at its rear end, remote from the barrel head 3 i, in a radial blind bore 6, which is perpendicular to the locking axis and whose diameter is slightly larger than the width of the recess 5. An extractor 7 is provided in the recess 5 inserted rectangular cross-section, the 'forward, towards the barrel head towards an extractor claw 8 and on his; rear end has a Zapf ice 9. The latter is Ms on two narrow lateral AbfräsirageB cylindrical i3i3d serves thereby,

that it engages in the somewhat wider blind hole 6 to give the extractor 7 support. Thanks to the play with which the pin 9 sits in the blind hole 6, the extractor 7 can execute radial pivoting movements that are caused by the deflection of the extractor claw 8 on the band 10 of the bottom of the cartridge 11 when the closure 1 is pushed forward. So that the extractor 7 automatically swivels back into its near-axis position, a bolt 13 engages on its shoulder 12, which is located in a detached guide bore 14 and is acted upon by a compression spring 15 when looking at the running head 3. The stepped notched bolt head 16 of the bolt 13 engages over the pin 9 dzs extractor 7 and thus prevents it from sliding out of the blind hole 6. A shoulder 17 protrudes backwards into the guide hole 14, behind which a threaded pin 18, which penetrates the guide hole 14 transversely, is in the cap 1 is screwed in. The threaded pin 18 serves as a stop for the bolt 13 and thus indirectly also limits the pivoting movement of the extractor 7 to the pivoting amplitude required for driving over the band 10 on the cartridge base. It is therefore important that the distance between the blind hole 6 and the threaded pin 18 and the length of the bolt 13 are precisely matched to one another. So that the rear end of the bolt 13 does not crush the sensitive threads of the threaded rod 18, it can be provided with a cylindrical twist at the stop point.

Fig. 2 shows a further embodiment in which instead of of the threaded pin 18 a threaded pin 19 is provided, which is in: a connecting hole 20 extending the guide hole 14 is screwed in is. This arrangement has the advantage that the swivel amplitude of the extractor 7 is set by turning the handle pin 19 and the band height can be adjusted for different types of cartridges.
