DE550900C - Automatic weapon with return tube and acceleration lock lever - Google Patents

Description

Automatic weapons with rewind, in which the breech block by means of an accelerator lever is repelled are known. However, the known designs have the disadvantage that the individual Organs of the mechanism are inadequately engaged with each other, resulting in a regular Functioning in question. In addition, the bodies concerned are with the

to previously known designs not arranged as expediently as it is required Safety and clarity of these weapons conditional.

It is therefore the main purpose of the invention, thanks to its arrangement, an inevitable Establish connection within the whole mechanism and at the same time alongside simple construction to ensure safe functioning and easy control options.

The invention is essentially characterized in that the accelerator lever and Closure piece directly interact and without the use of springs their intervention during the entire activity of the weapon, i.e. when moving backwards and forwards is maintained; therefore, the accelerator lever inevitably generates and affects the movements of the locking sleeve and lock directly and those of the other organs indirectly.

The drawings show, as an example, an embodiment of the weapon specifically for aircraft (Cartridge feed through belt).

They represent:

The slide 8, in which the shutter 7 is guided, is firmly connected to the pipe run 2 is (see Fig. ι to 3). Slide 8 in turn engages with a nose (see Fig. 3) the recess of the part 15 visible above in Fig. 4, so that this inevitably the same Moves like 2 and 8 executes or is locked together with them. The lever 14 has two arms; he swings around a pin 35, which in the fixed part of the weapon - in the base 1 - stored is. The lever 14 is actuated by the stop 3 8 of the part 15 (Fig. 2 and 3), and if his upper arm backwards (i.e. to the left in the pictures) is pressed, he in turn pushes against the nose 38 'of the locking piece 7, which is thus is also pushed back vigorously.

Immediately after the nose 38 'has detached itself from the tip of the lever 14, comes the surface 37 of the part 7 to rest against the lever tip and thereby holds the lever, in the position just assumed (Fig. 2). The lower arm of the lever with the cylindrical extension 36, which is on the Surfaces 39 of the part 15 slides along (Fig. 4), therefore also remains in position 2 blocked, in turn part 15 and thus via slide 8 also the pipe run 2 immovably locked in its retracted position. Part 15 will be at his Movements guided in corresponding guide grooves in the base 1.

The foregoing shows that the lever 14 is closed when The weapon is in the rest position (Fig. 3). After each shot, the barrel together with the slide 8 recedes a little and with them, first of all, the breech 7. "During this recoil comes a bolt 17, which has as long as part 7 and 8 coupled together, through inevitable displacement out of engagement with the lock 7 (see Fig. 5 to 7). the Displacement of 17 is achieved thanks to the shape of part 18, in its recess the nose 34 of the bolt is guided; 18 is with the fixed part of the Weapon connected and thus remains immovable. Until the moment of unlocking remains the upper arm of the lever 14 between the stops 38 and 38 '- to 8 and 7 respectively - firmly clamped, since parts 7 and 8 are initially still through the bolt 17 "are firmly coupled to one another; the lever 14 therefore initially swings a little around its pin 3 5 without coming into function.

As soon as the bolt 17 is the rigid connection between the carriage 8 and the shutter 7 has finally solved and both parts independently from each other, pipe run and part 8 continue their retrograde movement thanks to their large inertia, whereby they by means of the stop 38 on the front (right) surface of the upper lever arm 14 to press. Due to the shape of this arm, the point where the pushing movement moves is transferred to him, from the outer tip very quickly towards the pin 35, so that the tip with every millimeter The return path of the tube and slide increases on a larger scale Covered way. The lever 14 remains in constant engagement during this movement with the part 15, in that its roller 36 moves upwards along the surfaces 39.

While now the nose of the lever 14 with moving backwards (i.e. to the left) with increasing acceleration, it pushes against the front surface of the stop 38 'on the locking piece 7, on which it thus makes its impact movement transmits. However, while the movement of the locking piece gradually decelerates under the action of the recoil springs is, the firing pin 11 is within the breechblock further to the rear hurled by the living force of the receding masses or, in short: The carriage 8 runs together with the lock on a common path 7 back and then pushes it after the unlocking by part 17 under the action of the accelerator lever 14 backwards at an increased speed. The living force in the barrel 2, in the slide 8, in the breech 7 and in the firing pin 11 is accumulated, so becomes the recoil of the last two parts 7 and 11 used until it is completely consumed and the recoil springs are tensioned Has. '

At the moment when the carriage 8 comes to a standstill in its retrograde motion comes and the lever 14 has completed its rotation, the locking piece 7 gives way the action of the accelerator lever further back and thereby dissolves with his Stop 38 'from the tip of the lever. However, it continues to act by means of its surface 37 the lever arm, preventing it from returning to its original position. Consequently also its other arm with the roller 36 remains in engagement with part 15 (as in Fig. 2), and as a result, the carriage 8 and the pipe run 2 remain blocked in the position of the largest return path, since the parts 15, 8 and 2 with each other are rigidly connected.

When the shutter 7 after reversing its direction of movement back forward slides, its surface 37 gives the upper nose of the lever at a certain point in time 14 free again, so that this - taken by the stop 38 '- in the Position of Fig. 3 can turn back. In doing so, the front surface of his upper one presses Arms against the stop 38 of part 15 and thus presses the 'parts 15, 8 and 2 into the Starting position back, d. H. the gun closes again.

The movement of the accelerator lever 14 relative to the carriage 8 and the breech block 7 is completely inevitable. Because part 8 during the time when part 7 continues to recede unhindered and then slides forward again until it comes into contact with the locked carriage 8, remains in its recoil position

also the bolt 17 as long. out of engagement, which can only slide back into its starting position when the slide is 8 opposite the fixed part 18 the gun moves.

Claims (1)

Claim: Automatic firearm with return barrel and acceleration lock lever, characterized in that the lever system consists of two parts (14 and 15) which are in engagement with each other, both during the return and during the forward movement, one part (15) of which is rigidly connected to the guide carriage (8 ) for the socket and is connected to the barrel (2), while the other part (14) represents a double-barreled lever that swings around a bolt (35) anchored in the fixed part of the weapon, the upper arm of this lever (14 ) with the lock (7), the lower arm with a cylindrical extension (36) is permanently connected to the part (15) of the lever system connected to the guide carriage. 1 sheet of drawings
