Firearm Suppressor

Abstract

A suppressor includes baffles with geometry and spacing minimizing sound level in the human hearing range, and overlapping tapers on consecutive elements replacing welds. The geometry includes conical baffles with approach angles between 153.7 and 163.7 degrees and at least one inch separation. The suppressor is assembled by compressing the elements between threaded end caps, thus expending the overlapping tappers against the interior of a suppressor tube to center and align the baffles. The suppressor may be attached to a rifle using a quick disconnect mount which includes an adapter fixed to the rifle barrel and having an “L” shaped slot with a first leg parallel to the barrel and a second leg turned greater than 90 degrees towards the front of the adapter. A post in the suppressor engaged the slot and a spring biases the suppressor forward and holds the post at the end of the turned leg.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates firearm sound suppressors and in particular to a suppressor for automatic weapons.[0002]Firearms are often used in situations where the very loud sounds resulting from firing the weapons may both give away the position of the shooter or, especially indoors, temporarily deafen the shooter and others nearby. In a combat situation, giving away a shooters position may result in receiving hostile fire. Even temporary deafening may prevent communication between team members and prevent the shooter from hearing danger signs.[0003]Many known suppressors are available, but suffer from various deficiencies. Many do not reduce sound levels sufficiently.[0004]When used on automatic weapons, suppressor temperature may build quickly. Bullets are commonly constructed of jacketed lead.

AI Technical Summary

Benefits of technology

The invention is a firearm suppressor that reduces sound levels by using a minimum of three tapered baffles with interior angles between 15.3 and 26.2 degrees, which present an approach angle of 153.7 to 153.7 degrees and a separation of at least one inch between consecutive baffles. The combination of the tapered cones and the interior angles creates an acoustical dampening that attenuates sound waves. The perceived sound level is approximately 4 dB quieter in the human frequency range compared to known suppressors. The design also includes an overlapping of tapered surfaces and baffle spacing of at least one inch, which eliminates distortions caused by welds and machining processes. The suppressor is made of titanium to reduce weight and has a reduced temperature during automatic fire. The design also includes a quick disconnect mount and a spring retainer sleeve to prevent carbon buildup and failure of the suppressor.

Problems solved by technology

Firearms are often used in situations where the very loud sounds resulting from firing the weapons may both give away the position of the shooter or, especially indoors, temporarily deafen the shooter and others nearby.

In a combat situation, giving away a shooters position may result in receiving hostile fire.

Many known suppressors are available, but suffer from various deficiencies.

Many do not reduce sound levels sufficiently.

The lead softens quickly with temperature and melts at 621 degrees Fahrenheit which is a problem in known suppressors made of stainless steel and other materials which hold the heat inside the suppressor creating an oven like environment for the bullets to pass through.

This high temperature causes the lead to deform resulting in destabilizing the bullets as they pass through the suppressor causing baffle strikes and catastrophic failures.
