Method and apparatus for firearm sound suppression

Abstract

The method of the current invention provides means to maximize firearm suppressor efficiency with regards to maximizing sound attenuation while minimizing physical size and weight and minimizing firearm backpressure and manufacturing cost. In the preferred embodiment, the device consists of a closed cylinder within which is a separate closed inner cylinder of a lesser diameter and length. Holes coaxial with the assembly provide a means to attach the device to the firearm muzzle at the proximal planar end of the device, for the projectile and ejection mass to enter the proximal end of the inner cylinder and for the projectile and ejection mass to exit the device at the distal end of the device.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to and the benefit of U.S. Provisional Patent Application No. 62 / 160,004, filed May 12, 2015, entitled “METHOD AND APPARATUS FOR FIREARM SOUND SUPPRESSION,” which is hereby incorporated by reference in its entirety.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableBACKGROUND OF THE INVENTION[0003]Firearm suppressors, referred to by U.S. federal statutes as “silencers” or “mufflers,” are primarily designed to reduce unwanted effects of the muzzle blast and can also be made to improve the performance and accuracy of the weapon and shooter. The most commonly considered purpose of a suppressor is the reduction of the sound level pressure.BRIEF SUMMARY OF THE INVENTION[0004]The present invention muffles noises and reduces visible flash generated by the release of gasses and exploding propellant from a firearm muzzle. This is commonly and collectively referred to as firear...

AI Technical Summary

Benefits of technology

The present invention provides a device for reducing noise and flash generated by a firearm muzzle. It achieves this by using a two-stage suppression process where the gases and unexploded propellant enter a separate inner container and are forced through the projectile path hole. Compared to conventional suppressors, the present invention has advantages such as reduced pressure, improved propellant combustion efficiency, reduced material strength requirements, and improved barrel position stability.

Problems solved by technology

In the case of many automatic and semi-automatic firearms, the increased pressure caused by suppressors of the prior art adversely affects performance and mechanical durability of both the firearm and the suppressor and increases operator exposure to ejected gasses and propellant.

Additionally, the reduced pressure reduces the material strength requirements of key suppressor components.
