B. Machine gun nests to be destroyed, a serious and dangerous obstacle to the advancement of the infantryman represent.

At the present time, however, an infantryman is unable to perform this task when equipped:

- Either with a rifle, due to insufficient effectiveness

of the shot with projectiles, the result of which is random,
or due to lack of accuracy or range of
rifle grenades used in flat fire;

- or with a missile launcher, the task of which is essentially anti-tank, due to its space requirements, the relative weight of its ammunition and
their telltale signs.

The object of the invention is to create a shoulder-mounted individual weapon which has the above-mentioned disadvantages of the conventional Avoids weapons.

This problem is solved by the subject matter of claim 1.

Advantageous further developments of the invention are the subject of the subclaims.

Because of this anor-düüng the rifle scope is for improvement misplaced the viewing conditions, thereby creating the inconvenience of tilting the head for the operator the side is avoided.

The barrel is connected to the cradle via a hinge, which can be slid within the frame. The cradle and the frame form an integral part with mountings for the reverse brake.

Dtrs hinge allows the barrel to be opened at an angle at right angles for loading it and finally for ejecting the cartridge case.

A breech block contains the striking mechanism.

The cradle slides on guides formed within the frame. The length of this straight shift

corresponds to that of braking, which is 250 mra. There η μ an addition of 30 mm is provided as a security.

dung fire reduced. Towards the middle of its length, At about the point of its equilibrium point, the barrel is connected to the cradle 3 by a Gelei.k 2.

An ejector block located under the bullet chamber of barrel 1 12 carries the actual ejector 13 and its control mechanism.

The ejector 13 only works when the barrel 1 arrives at the end of the opening stroke. At this moment, a retaining pawl 14 hits a movable stop 15 adjacent to the ßohrwiege 3 vuaü releases the ejector 13, which is acted upon by a spring 16 and ejects the projectile casing. The spring 16 exerts the thrust via a piston 17 and a pin 18.

When the barrel 1 is closed, the ejector 13 is The plate 22 serving as a cam is retracted and held by the retaining pawl 14, which is inserted into the lateral guides of the ejector 13 incorporated retaining notches 19 inserted again is.

The ejection block 12 also contains a contact seat 20 for a bar 7

The tubular cradle 3 formed in one piece with the lock 5 as well as the mounting hub of the brake form only a single part. This part is generally made of light metal, for example Duralumin.

The cradle carries and guides the entire return mass through its sliding grooves 21 on each side and over the whole Length of the Rücklaufmasee are formed and in which the penetrating guides 8 of the frame slide.

Includes locking and striking mechanisms. It contains the steel plate 22 fastened to the block by a dovetail 23.

The plate 22 serves as a bottom stop for the cartridge case, as a slotted seat and allows the upper part to be weighed down of the weapon above the barrel axis to improve the balance of the weapon for the benefit of shooting accuracy.

The barrel is locked by the pivotable bolt 7, which is articulated on an axis 24 and by a Push rod 25 with Eugelzapfen in the locking position is pressed, the spring 26 of the push rod 25 being supported on the block of the closure 5.

Since the inner cross-section of the frame 4- completely through the translational movements of the return mass is used, the mechanical connection acting on the ignition control remains enclosed on the side of the frame and is consequently of this frame, which represents the non-returning mass protected.

The unlocking control (to the right of the shooter) takes place by a finger 27 firmly connected to the bolt 7, which is through a recess 28 passes through, which allows him sufficient deflection to perform the unlocking.

The finger 27 passes through the recess 28 to a groove 29 which is parallel to the guide 8 on the right flank of the cradle 3 is worked out and in which a stop 30 slides during its movement with respect to the return mass, which on the outside of the frame 4- is attached.

The stop 30 acts in the manner of a pawl when it interacts movable with the finger 27 only in one direction. It serves as a fixed stop at the end of the return stroke into the loading

reit shaft position of the return mass. During the meeting his contact surface 31 with the finger 27 he forces the bolt 7, Äie angular movement required for relocking to execute. The finger 27 rises during the angular movement and moves over the stop 30, which he passes to get back to his hat 29.

In the unlocked position, it is sufficient to release the barrel a fraction of a millimeter between the two edges of his seat.

The barrel is automatically locked again by lowering it.

At the beginning of the return stroke, the stop 30 works as a movable stop for releasing the passage of the finger 27 in the groove 29 without influencing the locked position of the fly 7-

For this purpose, engages d: s frontal end of the finger 27 on a ramp 30 of the stop 34- and presses the stop back in a horizontal plane.

The barrel can be unlocked manually in two ways:

- Either by pushing the barrel back slightly until the stop 30 is exceeded by the finger 27 and let him come back, unlocking then by moving backwards,

- Or by using a hand control and acting on a pulling attachment 35 that holds one in the groove slidable stop 36 takes to the Finger 27 in the same way as the stop 30 in the Return to the ready position to work.

.The entire control is provided by a spring-loaded Piston 38 returned to its neutral position. A

thin sheet. 39 ₅ that of a traversing. Pin 40 is held, closes the recess provided for the passage of the projection or lever 35 during its displacement.

The blow is carried out by a hammer 41, which is of a Nose 42 of the bolt 47 during its double bending movement is re-tensioned, which occurs during the opening and closing movements of the barrel.

In the course of this movement, the nose 42 presses the projection 43 of the hammer in a rotation about its axis 44 to an angle that a locking device 45 by its hairpin spring can snap into an incision 46. This angle corresponds to that of the stroke.

The hammer 41 is acted upon by a spring 47 thereof Rod thrown.

As described above, the triggering of the hammer is controlled on the outside of the return mass, on the left opposite the shooter. A displaceable plunger 48 transmits the action of a release lever 49 to the locking device 45 via its lifting stop 50.

When the release lever 49 of (FIG. 16) moving plunger ** Q raises the lift stop 50 are de ^T arrester 45 of the impact hammer 41 free.

once the shot has gone off, it lowers the returning ramp 51 the plunger 48, which remains in this low position during the entire return movement, due to the horizontal upper surfaces of the guide groove 21.

The lowering of the plunger 48 causes the release lever to be lowered 49 through its roller 52 and the moving together of its actuation levers 53

The mechanism is contained in a housing 60 which forms a single part with the handle 61. The arrangement can be completely removed by rotating the two bolts 62, which are used for fastening to the frame 4, by 180 °. \ -

This mechanism is provided with two fuses: a · fuse 63 for decommissioning and -a operational- | 55j fuse 5 · object of the latter is to prevent unwanted disengagement of the V of a shot by any l snagging with enabled latch. This operational security 55, 56 is canceled when the operator grips the handle due to the penetration of the lever 56 into the back of the handle 61. This results in the retraction of the rollers 55 ₅ which prevent the release lever 49 from causing the hate 41 to disengage.

the release lever 58 is set in its inactive position by an operational safety device, which by one of the action a spring 80 exposed lever 56 is formed. The lever 56 actuates a latch 81, which is connected to the inner surface of the housing 60 and the lower surface of a trigger 82 cooperate. This lower surface of the fume cupboard has a shoulder 83 »so that the trigger is under the action of the release lever 58 can pivot about an axis 84 when the bolt 81 is in the advanced position.

The trigger has a pawl 85 which swivels about an axis 86 and is subjected to the action of a spring 87 which moves it into Attachment to a pin 88 holds. The pawl 85 has a surface 89 which cooperates with the end of an arm of a deflection 90, the other arm, which is offset by 90 °, has a hook 91 cooperating with the plunger 48. At this Execution, the plunger 48 strives to be moved upwards by a spring, not shown.

The return brake is of a hydraulic type with partial energy recovery by compressing a previously partial compressed spring 9> which is used to ensure a correct end of stroke when the The barrel in the ready position is used regardless of the inclination of the weapon.

The body 6 of the cylinder is. Part of the Kücklau mass, with which he through the fastenings 64 and 65 of the movable tube - .. cradle 3 is firmly connected. Its rod 10, onto which a piston 66 is screwed, is immovable with respect to the frame and held in the adjustment by its locking end piece 67.

During the displacement of the movable relative to the rod cylindrical body 6 of the brake, the oil contained in the body reaches the opposite of the displacement of the body from one side to the other of the stationary piston 66.

- 13 -

In one of the construction forms shown, the Passage of the oil through a clearance provided between the piston 66 and the body 6, the linear decrease of which is the progressivity the braking during the displacement of the body relative to the piston 66 brings about.

This effect enables a reduction in the reaction that occurs when the weapon is raised before the projectile emerges from it want to bring about the barrel of the barrel.

To prevent it from flaming, the spring is partly through the rod 10 and partly guided through the sleeve 70.

The return mass in the transport position is held by a supporting latch that automatically engages in a cavity at the rear of the breech block when the return mass exceeds the limit of the return stroke. The pawl can be released by exerting a thrust on a corrugated area 71.

A stop 72 protects the piston 66 by preventing it from resting against the bottom of the cylinder during one of He.nd executed strokes to shorten the weapon in the transport position or, if necessary, to record the crossing of the limit of the return stroke.

A telescopic sight 73 has a magnification of two times. The telescopic sight is detachable on the left side of the weapon and is necessarily attached to it by a dovetail 74- which fixes the telescopic sight in its position and allows it to be released in order to remove it from the weapon.

The attachment of a movable crosshair allows a ng of the rifle scope.

The Euss 75 is used in a vertical position to

execution of a shot with support on the ground. The foot is fixed in this position by a bolt 76.

In horizontal forward position (complete opening? 180 °) the foot serves as a protection for the barrel to prevent it from rubbing with the muzzle brake during the return movement or get stuck when a shot is at any Support is carried out.

For transport, the foot is under the shaft of the barrel foldable and is in this position by the bolt 76

detected.

It can thus be seen that the operation of the weapon according to the invention is very simple and for its operator has all security.

If a shot goes off, the barrel, the tube cradle and the brake body move back in the frame and press the return spring together. The braking device is designed such that u at the beginning of the shot? S energy consumption takes place gradually, which limits prior to complete exit of the projectile from the barrel of the reaction to the weapon.

When the return stroke has ended, the return spring returns the return mass to the front. A little before the end When returning to the ready position, a stop located on the frame triggers the unlocking and the automatic ..open the barrel.

The bullet case is ejected at the end of the angled opening of the barrel.

Each of the introduction on the one new ammunition in the chamber of the barrel it is _r by lowering its cradle closed and will automatically lock.

The movement of the bolt during this process causes this
re-tension the impact mechanism.

The shifting of the trigger causes the plunger to move upwards, which removes the locking device from the holding groove of the hammer
releases. The firing pin is then on the primer
Cartridge thrown.
