US-12618633-B2 - Gun barrel brush

Abstract

A cleaning tool for ported firearm barrels with integrated suppressors is disclosed. The tool comprises a cylindrical brush housing with an inner cavity to accommodate a barrel brush insert featuring radially extending bristles for removing carbon deposits and debris. A retaining washer and clip secure the brush insert within the housing. The assembly includes a cylindrical handle with internal threading to engage the housing's threaded neck, and an externally knurled surface for improved grip. The brush insert is interchangeable, allowing various cleaning media such as stainless steel, alloy steel, Aluminum, Bronze, Nylon, Brass, Plastic, Polypropylene, rubber, or other metals. The design eliminates the need for firearm disassembly and avoids reliance on the suppressor as a cleaning component, enhancing user safety and preserving firearm integrity. This tool facilitates efficient maintenance of firearms with integrally suppressed systems, promoting reliability and extending the lifespan of the firearm.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims benefit to Provisional Application No. 63/651,651 filed May 24, 2024, the contents of which are herein incorporated by reference. BACKGROUND OF THE INVENTION The present disclosure pertains to mechanical cleaning tools, specifically to brushes designed for cleaning ported gun barrels on firearms with integrated suppression systems. The field of firearm maintenance often involves the use of specialized cleaning tools designed to address the challenges presented by modern firearms. Many cleaning devices have been developed to remove carbon deposits and general grime from gun barrels, an important step in promoting reliable firearm operation. These tools typically focus on cleaning the interior surfaces or make use of components that are part of the firearm's integrated systems, such as the suppressor. In this context, maintaining performance while reducing the complexity of the cleaning process is a continual objective for manufacturers and users alike. However, the specific construction of some firearms creates challenges that conventional cleaning tools have yet to fully address. In many applications, there is a desire for cleaning devices that facilitate routine maintenance without necessitating extensive disassembly of the firearm. Users benefit from solutions that streamline the cleaning process while still effectively removing residues that can impair performance. The applicative goal is to create a tool that allows thorough cleaning of difficult-to-access areas while preserving the integrity of delicate components, such as the suppressor. Improved cleaning efficiency can contribute to both the longevity of the device and the safety of the operator, especially in scenarios where traditional methods may prove cumbersome or unsafe. Generally, challenges in the cleaning process arise when conventional tools require the user to either access internal surfaces through complete disassembly or depend on components that may be sensitive to misuse. Some designs require users to interact with parts of the firearm that may be adversely affected by high temperatures or repetitive handling, such as the suppressor, thereby increasing the risk of inadvertent damage. The complexity of cleaning assemblies can also discourage regular maintenance, potentially leading to performance issues or premature wear. Without a user-friendly tool, the routine upkeep of such firearms becomes both time consuming and labor intensive. Specifically, difficulties emerge when the cleaning process involves contact with areas that are exposed to excessive heat or that possess vulnerable surfaces. In certain cases, tools on the market have required the application of cleaning forces through mechanisms that are not optimally designed for this purpose, risking harm to sensitive components. Such approaches may inadvertently compromise the durability of the firearm and elevate safety concerns for the operator. There is a clear need for a cleaning solution that minimizes these risks while enabling effective removal of contaminants from challenging areas without resorting to full disassembly or using components in unintended ways. SUMMARY OF THE INVENTION In one embodiment, the disclosure provides a barrel brush assembly that includes a substantially cylindrical brush housing defining an inner cavity configured to receive a firearm barrel and featuring a threaded neck at one end. The assembly further comprises a removable barrel brush element having a body from which a plurality of bristles extend radially inward and which is formed of a first cleaning medium. A retaining washer is removably positioned within the cavity in contact with the barrel brush element, and a retaining clip is also removably disposed in the cavity to secure both the barrel brush element and the retaining washer in place. Additionally, the assembly includes a substantially cylindrical handle having an inner diameter configured to receive the firearm barrel and an internal threaded surface arranged to engage the threaded neck of the brush housing. In another embodiment, the barrel brush assembly incorporates an additional interchangeable barrel brush element having a body with a plurality of bristles that extend radially inward, the bristles being formed of a second cleaning medium, and configured to replace the primary barrel brush element within the cavity. In some embodiments, the first cleaning medium is selected from the group consisting of steel, aluminum, bronze, brass, plastic, nylon, polypropylene, or rubber, and the second cleaning medium may be similarly selected. Other embodiments include features in which the outer surface of the barrel brush element's body exhibits a first knurling, and the outer surface of the handle exhibits a second knurling.
