Abstract
A cylindrical silencer tube is fastened to the muzzle of a firearm. The interior of the tube is equipped with a series of chambers and conically shaped baffles which direct part of the discharge gases and sound waves in a different path from the main discharge and then causes them to reunite before they discharge the silencer at a point where part of the sound waves have been delayed and are hence out of phase with the principal waves and cause elimination of the noise. Specially constructed inlet and outlet chambers within the tube aid in the suppression of the sound waves and deafening of the noise. The exterior of the cylindrical silencer tube is equipped with a series of cooling fins to aid in the dissipation of heat from the silencer.
Claims9
A silencer for a firearm comprising:
- (a) a cylindrical tube having a longitudinal axis;
- (b) means for attaching said tube to a muzzle of said firearm such tat said axis is coaxially aligned with the bore of said firearm;
- (c) said tube having positioned in its interior a plurality of elements disposed for guiding of expanded gases and transmitting of sound waves from the end of said muzzle towards the outside of said tube, said elements being concentrically positioned along said axis of said tube, said elements including:
- (1) a first flange member positioned within the interior of said tube;
- said flange member having a central conical portion with an opening within the apex end of said conical portion, said apex end facing the muzzle of said firearm, said opening concentric to said central conical portion, said flange member further having a truncated cone shaped surface located on the outer diameter of said member, the wider end of said truncated cone shaped surface facing said muzzle and being concentric with said tube axis;
- (2) a first hollow cylindrical member having an outer diameter smaller than the inside diameter of said tube and having a plurality of radial holes through its periphery;
- (3) a plurality of hollow conical baffling members in the form of truncated cones with their apexes facing said muzzle of said firearm, each said conical member positioned in sequence along the axis in the interior of said tube, each of said conical members having an array of holes substantially circularly disposed around the periphery of said conical members, said conical members having their widest end extended close to the interior surface of said tube, each said array of holes being located farther from the apex of its respective conical member than the array of the previous conical member;
- (4) a second hollow cylindrical member having an outside diameter of said first cylinder and less than the inside diameter of said tube and having a array of radial holes disposed around the periphery, of said cylindrical member positioned such that the ends of said cylindrical member abuts the sides of said conical member;
- (d) all of said elements firmly bonded together to form a first unit, said unit being fitted into said interior of said tube.
The device of claim 6 further comprising an exit unit comprising an outer hollow cylindrical member concentrically disposed about said axis of said tube in the interior of the end of said tube opposite to said entrance end of said tube;
- a second flange member positioned within the interior of said outer hollow cylindrical member and disposed at the end of said outer hollow cylindrical member facing said muzzle;
- said second flange member shaped and oriented like said first flange member;
- said outer cylindrical member having a closed end surface at its end facing away from said muzzle, said end surface having a central opening concentrically disposed to said axis of said tube;
- an inner cylindrical member of smaller diameter than the inside diameter of said outer cylindrical member coaxially disposed within said outer cylindrical member, said inner cylindrical member having a plurality of radial holes therethrough.
