Mechanism for firearms and its working method

Abstract

The invention is a monoblock submachine gun part that is housed within the upper body, that pushes the round in the magazine into the shell chamber, that houses the pin system which fires the round in the shell chamber by triggering the explosion of its capsule, that pulls the empty shell in the shell chamber with the lug on it, and that winds the cock which has the function of hitting the pin for a second shot as it moves back due to the power of the recoil.

I claim: 
     
         1 . A mechanism for firearms comprising:
 at least one frontal profile of the mechanism that directly enters into the barrel as it pushes the round from the magazine into the barrel round chamber wherein the mechanism manufactured as a monoblock part.   
     
     
         2 . The mechanism of  claim 1  further comprising:
 at least one winding arm that is integrated to the mechanism at its top section and that allows the mechanism's forward and backward movement together with the upper body; 
 at least one pin housing with different diameters set in the mechanism; 
 at least one pin and coil spring placed inside the said pin housing, which fires the round; 
 at least one ejection window through which the empty shell is ejected after the firing of the round; 
 a plurality of channels that prevent the mechanism from scuffing the magazine walls and the neck portion of the fixed ejector as the mechanism moves forward and backward along the barrel's axis; and 
 side ejections built along the length of the mechanism that decrease overheating by decreasing the friction surface as the mechanism works inside the upper body without deviating from the working axis. 
 
     
     
         3 . A method of the mechanism of  claim 1  the method comprising:
 the upper body's getting in contact with the winding lug on the mechanism and pulling the mechanism in the same direction of its movement when a winding arm that is connected to the upper body is pulled backwards; 
 compressing of the absorber buffer coil spring that is behind the mechanism, due to the movement of the mechanism; 
 moving forward under the influence of the coil spring, when the pulling force applied to the winding arm is released; 
 pushing of the round from the magazine into the barrel round chamber by the front profile of the mechanism; 
 firing of the round that is in the round chamber, and thus the firearm, by the pin of the mechanism; 
 moving backward due to the explosion after the round is fired; 
 pulling of the empty shell by the lug on the mechanism as the mechanism moves backward; 
 ejection of the empty shell that moves backward along the barrel axis through the ejection window by its changing direction due to its back hitting the fixed ejector; 
 getting ready for the firing of a new round. 
 
     
     
         4 . A method of the mechanism of  claim 2  the method comprising:
 the upper body's getting in contact with the winding lug on the mechanism and pulling the mechanism in the same direction of its movement when a winding arm that is connected to the upper body is pulled backwards; 
 compressing of the absorber buffer coil spring that is behind the mechanism, due to the movement of the mechanism; 
 moving forward under the influence of the coil spring, when the pulling force applied to the winding arm is released; 
 pushing of the round from the magazine into the barrel round chamber by the front profile of the mechanism; 
 firing of the round that is in the round chamber, and thus the firearm, by the pin of the mechanism; 
 moving backward due to the explosion after the round is fired; 
 pulling of the empty shell by the lug on the mechanism as the mechanism moves backward; 
 ejection of the empty shell that moves backward along the barrel axis through the ejection window by its changing direction due to its back hitting the fixed ejector; 
 getting ready for the firing of a new round.
