Description

BACKGROUND OF THE INVENTION

1) Field of the Invention

The present invention relates to a suppressor that is configured to be attached to or be part of the barrel of a firearm or air gun to reduce the amount of noise and visible muzzle flash generated by firing a projectile.

2) Description of Related Art

Firearm suppressors typically include a series of stacked baffles received into and secured by a cylindrical housing that is attached to the muzzle of a gun barrel. The baffles stack is designed to reduce the pressure, temperature, and velocity of projectile gas that escapes the firearm muzzle when the firearm is discharged. Typically, improvements to suppressor involves varying designs to the baffles or the baffle stack as shown in U.S. Pat. No. 9,239,201. In this disclosure, each baffle includes a frusto-conical sidewall having an apex opposite a base. The apex includes an axial bore and is disposed towards the receiving bore. The base is disposed toward the discharge bore. The apex includes a semi-circular cut from the sidewall into the axial bore, forming a semi- circular protrusion. The disadvantage is that tremendous pressure is placed on the baffle as the gas is redirected at an extreme angle reducing the life and usefulness of the suppressor.
Accordingly, it is an object of the present invention to provide for a unique baffle stack that redirects expanding gases asymmetrically to create turbulence in the gas stream and further reduce the noise reduction ability of the suppressor.

SUMMARY OF THE INVENTION

The above objectives are accomplished according to the present invention by providing a firearm suppressor for reducing the amount of noise generated from a firearm comprising: a baffle stack having a plurality of baffles received in an outer tube wherein a first baffle is received into an adjacent baffle; a piston assembly and an endcap removably attached to the outer tube; a piston housing, piston cap and piston spring included in the piston assembly; a first concave section defined in an aperture including in at least one baffle; a second concave section defined in an aperture including in at least one baffle wherein the first concave section and the second concave section are offset relative to a diameter bisecting the baffle; a plurality of ports defined in the outer tube disposed forward of a midpoint in the outer tube configured to shift the center of mass to the rear of the outer tube; and, an end cap removably attached to the outer tube.
A first concave section and the second concave section can be disposed on the same side of the diameter bisecting the baffle. A first baffle can have a height less than a second baffle. An engagement ring can be defined in at least one baffle configured to receive a lower edge of an adjacent baffle to create the baffle stack. A sloped upper side can extend from the engagement ring and terminate at the aperture of at least one baffle. A short lip and a long lip can be included in the aperture. The first concave section and the second concave section can be disposed between the short lip and the long lip.
A first set of ports can be defined in the outer tube that are offset relative to a second set of ports defined in the outer tube. The ports can be in any number of arrangement. In one embodiment, the plurality of ports are disposed forward of a midpoint in the outer tube configured to shift the center of mass to the rear of the outer tube.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

With reference to the drawings, the invention will be described in more detail. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which the presently disclosed subject matter belongs. Although any methods, devices, and materials similar or equivalent to those described herein can be used in the practice or testing of the presently disclosed subject matter, representative methods, devices, and materials are herein described.
Referring to FIG. 1, a suppressor 10 is shown having an outer tube 12. The suppressor includes an attachment end 14 and a distal end 16. The outer tube includes ports 20 defined in the outer tube exposing a baffle stack exposing the baffles to the ambient environment external to the outer tube. In one embodiment, the ports are oblong along an axis 22. The ends of the ports can have a concave shape relative to the opening defined by the port. In one embodiment, there is a first row of ports adjacent to a second row of ports wherein the first row of ports includes a number of ports greater than the second row of ports. The ports can take many shapes, arrangement and configurations. In one embodiment, the majority of the ports are disposed at the distal end 24 of the outer tube thereby shifting the center of gravity toward the proximal end of the outer tube. In one embodiment, a first set of ports can be defined in the outer tube that are offset relative to a second set of ports defined in the outer tube wherein the first set of ports includes more ports than the second set of ports.
Referring to FIG. 2, piston assembly is included having a piston cap 26 removably connected to the outer tube. The piston assembly includes a piston housing that covers the piston 28 and contacts piston spring 30. The piston spring compresses against the baffle stack when attached to the outer tube. The piston and piston spring are received in a piston housing 32. A plurality of baffles such as 34 are disposed in the housing and compressed into each other by the piston spring when received on the housing. An end cap 36 is removably attached to the outer tube and secures the baffles in the outer tube. In one embodiment, one baffle 38 can have a height less than a second baffle 40. In one embodiment, a shorter baffle can be in the baffle stack and disposed adjacent to the endcap.
In one embodiment, the outer tube is removable attached to the piston housing and the piston cap is removable attached to the piston housing. The spring contacts the rear most baffle forcing the rearmost baffle against the adjacent baffle and so on.
Referring to FIG. 3A, a baffle is shown. The baffle includes an aperture 42 defining an aperture opening 42 a. The aperture is where the project enters the baffle. The baffle can include a first concave section 44 a and a second concave section 44 b defined in the edge of the aperture. The aperture includes a short lip 46 a and a long lip 46 b. Referring to FIG. 3B, the baffle can include a lower portion 48 that include an engagement ring 50 that can receive the lower edge 50 of the adjacent baffle to create the baffle stack. Sloped upper sides 52 extend from the engagement ring and terminate at the aperture. Referring to FIG. 3C, the first concave section and the second concave section can be disposed on one side of a diameter 54 of the baffle. The baffle stack can be aligned so that all concave sections are disposed on one side of the baffle stack or can be intermixed. In one embodiment, the baffle stack can have alternating baffles of one of a shorter height adjacent to one of a larger height.
Referring to FIG. 4, the baffles can alternate in rotational orientation along the baffle stack. The first baffle 56 can have a first orientation where the concave sections are generally positioned in the north west position. The next adjacent baffle 58 can have the concave sections which are generally positioned in the north east position. The next adjacent baffle 60 can have the concave sections which are generally positioned in the west-south west position. The next adjacent baffle 62 can have the concave sections which are generally positioned in the east-south east position. In this embodiment, the concave section are not aligned with the concave section of the adjacent baffles. The rotational arrangement need not be systematic between baffles, but any rotational difference between baffle in a range of 0° to 359°.
In one embodiment, the concave sections of the baffles in the baffle stack are rotationally offset a unique number of degrees relative to the adjacent baffle. In this embodiment, the offset of one baffle, measured in rotational degrees, is unique to any set of adjacent baffles.
