Abstract

A firearm suppressor for dissipating the energy of discharge gases expelled by a discharge of a firearm has at least a first baffle and a second baffle, each baffle having a circumferential outer wall for enclosing an expansion chamber. The outer wall has a circumferential forward tapered surface and a circumferential rearward tapered surface, a taper angle of the forward tapered surface being equal to a taper angle of the rearward tapered surface. The baffles are assembled together in a coaxial baffle stack with the first baffle forward of the second baffle, the forward tapered surface of the second baffle engaging the rearward tapered surface of the first baffle for forming a tapered seal between the outer walls of the baffles, thereby limiting flow of firearm discharge gases from within the baffle stack through the tapered seal.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A firearm suppressor for dissipating the energy of discharge gases expelled by a discharge of a firearm, the suppressor comprising:
 at least a first baffle and a second baffle, each baffle having a circumferential outer wall for enclosing an expansion chamber, the outer wall having a circumferential forward tapered surface and a circumferential rearward tapered surface, a taper angle of the forward tapered surface being equal to a taper angle of the rearward tapered surface;   wherein the baffles are assembled together in a coaxial baffle stack with the first baffle forward of the second baffle, the forward tapered surface of the second baffle mating with the rearward tapered surface of the first baffle for forming a tapered seal between the outer walls of the baffles, thereby limiting flow of firearm discharge gases from within the baffle stack through the tapered seal.   
     
     
         2 . The firearm suppressor of  claim 1 , further comprising:
 a tube configured to be coupled to a firearm near a muzzle of the firearm, the baffles being located within the tube.   
     
     
         3 . The firearm suppressor of  claim 1 , further comprising:
 a tube configured to be coupled to a firearm near a muzzle of the firearm, the baffles being located within the tube, the tube having at least one open end configured to allow insertion and removal of the baffles; and   an end cap for each open end, each end cap being configured to be removably attached to the open end, each end cap having a circumferential tapered surface configured to mate with one of the tapered surfaces of an adjacent baffle.   
     
     
         4 . The firearm suppressor of  claim 1 , wherein the outer wall of each baffle comprises internal threads and external threads, one of the threads of the first baffle engaging the other of the threads of the second baffle for retaining the baffles together in the stack. 
     
     
         5 . The firearm suppressor of  claim 1 , wherein for each baffle the forward tapered surface forms a forward end of the outer wall. 
     
     
         6 . The firearm suppressor of  claim 1 , wherein for each baffle the rearward tapered surface forms a rearward end of the outer wall. 
     
     
         7 . The firearm suppressor of  claim 1 , wherein for each baffle the forward tapered surface is rearward of a forward end of the outer wall. 
     
     
         8 . The firearm suppressor of  claim 1 , wherein for each baffle the rearward tapered surface is forward of a rearward end of the outer wall. 
     
     
         9 . The firearm suppressor of  claim 1 , further comprising:
 a second forward tapered surface, the forward tapered surfaces intersecting to form a V-shaped groove; and   a second rearward tapered surface, the rearward tapered surfaces intersecting to form a V-shaped ring;   wherein the groove of the second baffle receives the ring of the first baffle, each forward tapered surface mating with the corresponding rearward tapered surface, thereby forming two adjacent tapered seals between the outer walls of the baffles.   
     
     
         10 . The firearm suppressor of  claim 1 , further comprising:
 a second forward tapered surface, the forward tapered surfaces intersecting to form a V-shaped ring; and   a second rearward tapered surface, the rearward tapered surfaces intersecting to form a V-shaped groove;   wherein the groove of the first baffle receives the ring of the second baffle, each forward tapered surface mating with the corresponding rearward tapered surface, thereby forming two adjacent tapered seals between the outer walls of the baffles.   
     
     
         11 . A firearm suppressor for dissipating the energy of discharge gases expelled by a discharge of a firearm, the suppressor comprising:
 at least a first baffle and a second baffle, each baffle having a circumferential outer wall for enclosing an expansion chamber, the outer wall having a circumferential forward tapered surface and a circumferential rearward tapered surface, a taper angle of the forward tapered surface being equal to a taper angle of the rearward tapered surface;   a tube configured to be coupled to a firearm near a muzzle of the firearm, the baffles being located within the tube, the tube having at least one open end configured to allow insertion and removal of the baffles;   an end cap for each open end, each end cap being configured to be removably attached to the open end, each end cap having a circumferential tapered surface configured to mate with one of the tapered surfaces of an adjacent baffle; and   wherein the baffles are assembled together in a coaxial baffle stack with the first baffle forward of the second baffle, the forward tapered surface of the second baffle mating with the rearward tapered surface of the first baffle for forming a tapered seal between the outer walls of the baffles, thereby limiting flow of firearm discharge gases from within the baffle stack through the tapered seal.   
     
     
         12 . The firearm suppressor of  claim 11 , wherein for each baffle the forward tapered surface forms a forward end of the outer wall. 
     
     
         13 . The firearm suppressor of  claim 11 , wherein for each baffle the rearward tapered surface forms a rearward end of the outer wall. 
     
     
         14 . The firearm suppressor of  claim 11 , wherein for each baffle the forward tapered surface is rearward of a forward end of the outer wall. 
     
     
         15 . The firearm suppressor of  claim 11 , wherein for each baffle the rearward tapered surface is forward of a rearward end of the outer wall. 
     
     
         16 . The firearm suppressor of  claim 11 , further comprising:
 a second forward tapered surface, the forward tapered surfaces intersecting to form a V-shaped groove; and   a second rearward tapered surface, the rearward tapered surfaces intersecting to form a V-shaped ring;   wherein the groove of the second baffle receives the ring of the first baffle, each forward tapered surface mating with the corresponding rearward tapered surface, thereby forming two adjacent tapered seals between the outer walls of the baffles.   
     
     
         17 . The firearm suppressor of  claim 11 , further comprising:
 a second forward tapered surface, the forward tapered surfaces intersecting to form a V-shaped ring; and   a second rearward tapered surface, the rearward tapered surfaces intersecting to form a V-shaped groove;   wherein the groove of the first baffle receives the ring of the second baffle, each forward tapered surface mating with the corresponding rearward tapered surface, thereby forming two adjacent tapered seals between the outer walls of the baffles.   
     
     
         18 . A baffle for a firearm suppressor, the baffle comprising:
 a central cone having a bore configured to allow a projectile to pass through the bore; and   a circumferential outer wall, the outer wall having a circumferential forward tapered surface and a circumferential rearward tapered surface, a taper angle of the forward tapered surface being equal to a taper angle of the rearward tapered surface;   wherein the cone and wall cooperate to define an expansion chamber.   
     
     
         19 . The baffle of  claim 18 , wherein the forward tapered surface is rearward of a forward end of the outer wall.
