Baffle for a firearm suppressor

Abstract

The present invention describes a baffle for use in a firearm suppressor or silencer. The baffle is a hollow tubular body of cylindrical cross section casing narrowing to a cone shape having sides that define an inlet and outlet. The baffle walls of the subject invention are thicker towards the bore of the suppressor making it more resistant to the heated pressurized gases and other elements traveling through the suppressor or silencer.

RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Application No. 62 / 490,252 filed Apr. 26, 2017. The entire contents of the above application are hereby incorporated by reference as though fully set forth herein.BACKGROUND[0002]This invention relates to suppressors or silencers for firearms. More particularly, this invention relates to specialized firearm barrel adaptations for suppressing gunfire noise.[0003]To fire a bullet from a firearm, gunpowder is ignited behind a bullet. The gunpowder creates a high-pressure pulse of hot gas. The pressure of the gas forces the bullet down the barrel of the gun. When the bullet exits the end of the firearm barrel, the pressure behind the bullet is immense and just like popping the cork on a bottle; the “pop” sound it creates is very loud. The sound is from the initial pressure wave coming out the barrel. Additional gas comes out after the initial pressure wave but not as much as the initial wave.[0004]Known suppr...

AI Technical Summary

Benefits of technology

The present invention is a baffle for use in a firearm suppressor or silencer. The baffle has a thicker wall towards the bore of the suppressor and is designed to reduce noise and improve the performance of firearms. The baffle has a cylindrical shape with an interior and exterior surface and is nested with complimentary baffles within a tubular housing. This design helps to further reduce noise and improve the overall performance of firearms.

Problems solved by technology

The baffles within the suppressors are needed to divert the gas from the bore in order to allow the gas to expand and depressurize; but, if the suppressor or silencer is too efficient in slowing gas down, it builds up an excess amount of pressure in the firearm barrel and causes the firearm to malfunction.

These baffles are typically formed of metal and are subjected to wear and corrosion caused by the explosive gases entering the housing.

After a limited number of rounds, the baffles fail, particularly the first baffle.

In order to increase the lifespan of the baffles, and consequently the lifespan of the suppressor or silencer, one must use materials that are hard to machine, which increases manufacturing costs.

The entire suppressor or silencer is subject to an additional federal tax, which increases the cost of replacement.

There is a point of diminishing returns on efforts to eliminate sound from a firearm since a suppressor cannot eliminate the supersonic shockwave, or “crack” caused by the bullet traveling in excess of the speed of sound.

Finally, traditional baffles are limited in their wall thickness as the edge that interfaces with the spacer of the tubular casing requires a maximum thickness simply because the edge needs to be properly welded to the tubular casing.
