Compact space saving gun silencer

Abstract

A compact silencer (suppressor) device for a firearm including multiple chambers which trap the gases from a projectile exiting the barrel of a gun to slow down the gases and reduce the temperature, sound, and flash associated with the projectile. In one embodiment, the first chamber which attaches to the barrel of the firearm includes sound baffling materials or gas porting baffles which vent gases from the second chamber passing rearward. The second chamber includes a chamber which can accommodate a retractable third chamber of the device, the second and third chamber of the device can have sound baffles to slow down the gases from the projectile.

What is claimed is: 
     
         1 . A silencer apparatus for suppressing a sound of a projectile fired from a firearm, the silencer apparatus comprising:
 a first chamber and a second chamber, each of the first chamber and the second chamber having a cylindrical, oval, or rectangular shape;   the first and second chambers being aligned longitudinally and sequentially along a bore line, wherein the bore line is coaxial with a longitudinal bore axis of a barrel of the firearm when the silencer apparatus is installed on the firearm;   the first chamber comprising a first end cap on a proximal end thereof,   and   a second end cap concentric with the bore line and including a concentric annular opening around the gun barrel and encompassing the gun barrel, the second end cap having a mechanical connection system for attaching to the end of the gun barrel such that the bore line and longitudinal bore axis are aligned;   the first end cap having a mechanical connection system for attaching the silencer apparatus to the second end cap along the bore line of the barrel of the firearm;   a guide ring formed on a distal end of the second end cap, the guide ring being concentric with the bore line and the concentric annular opening of the first end cap, and   the guide ring being beveled along a distal side thereof and extending distally from the first end cap, the guide ring providing an interface and alignment guide for the second chamber coming into contact with the guide ring along the bore line;   the first chamber further including a mechanical spring;   the mechanical spring being internal to the first chamber and biasing the second chamber into a retracted position in which the second chamber is retracted into the first chamber,   wherein the second chamber is movable relative to the first chamber longitudinally along the bore line from the retracted position to an expanded position, against the bias of the mechanical spring,   wherein a second flange on the proximal end of the second chamber contacts with the guide ring, such that the beveled portion of the guide ring causes the second chamber to align concentrically with the bore line, when the second chamber is in the retracted position,   wherein the silencer apparatus allows a projectile fired from the firearm to travel along the bore line through the first chamber and the second chamber.   
     
     
         2 . A method to silence or to suppress a sound of a projectile being fired from a firearm, the method comprising:
 providing a silencer apparatus comprising:   a first chamber and a second chamber, each of the first chamber and the second chamber having a cylindrical, oval, or rectangular shape;   the first and second chambers being aligned longitudinally and sequentially along a bore line, wherein the bore line is coaxial with a longitudinal bore axis of a barrel of the firearm when the silencer apparatus is installed on the firearm;   the first chamber comprising a first end cap on a proximal end thereof,   and   a second end cap concentric with the bore line and including a concentric annular opening around the gun barrel and encompassing the gun barrel, the second end cap having a mechanical connection system for attaching to the end of the gun barrel such that the bore line and longitudinal bore axis are aligned;   the first end cap having a mechanical connection system for attaching the silencer apparatus to the second end cap along the bore line of the barrel of the firearm;   a guide ring formed on a distal end of the second end cap, the guide ring being concentric with the bore line and the concentric annular opening of the first end cap, and   the guide ring being beveled along a distal side thereof and extending distally from the first end cap, the guide ring providing an interface and alignment guide for the second chamber coming into contact with the guide ring along the bore line;   the first chamber further including a mechanical spring;   the mechanical spring being internal to the first chamber and biasing the second chamber into a retracted position in which the second chamber is retracted into the first chamber,   wherein the second chamber is movable relative to the first chamber longitudinally along the bore line from the retracted position to an expanded position, against the bias of the mechanical spring,   wherein a second flange on the proximal end of the second chamber contacts with the guide ring, such that the beveled portion of the guide ring causes the second chamber to align concentrically with the bore line, when the second chamber is in the retracted position,   wherein the silencer apparatus allows a projectile fired from the firearm to travel along the bore line through the first chamber and the second chamber.
