PULL-THROUGH APPLICATOR ASSEMBLY FOR A FIREARM
A pull-through applicator assembly for maintenance of a gun barrel. The pull-through applicator assembly is a unitary, disposable, and configured for easy manufacturing relative to conventional pull-through assemblies. The economics of the disclosed pull-through applicator assembly is sufficient to permit packaging and sale as a disposable unit, for discarding after a single use. The single-use aspect enables the fibrous body to be configured primarily for compliance to the internal geometry of the gun barrel (e.g., the grooves of the rifling) without need for considering the durability over multiple uses. Accordingly, enhanced contact with the internal geometry of the gun barrel is realized in the convenient form of a pull-through applicator that is disposable. The pull-through applicator may be configured of biodegradable materials to enhance the disposable aspect.
1 . A pull-through applicator for maintenance of a gun barrel, comprising:
a braided cord including strands that are interwoven, and having first and second ends, the braided cord including a first portion and an expanded portion extending from the first portion proximal to the second end, the expanded portion having a diameter larger than a diameter of the first portion and forming a mesh; and
a fibrous applicator body disposed in the expanded portion and surrounded by the mesh, wherein the mesh covers a majority of an outer surface of the fibrous applicator body.
2 . The pull-through applicator of claim 1 , further comprising a guide weight coupled to the first end.
3 . The pull-through applicator of claim 1 , wherein the fibrous applicator body is substantially cylindrical.
4 . The pull-through applicator of claim 1 , wherein the braided cord, and the fibrous applicator body are biodegradable.
5 . The pull-through applicator of claim 1 , wherein the mesh covers about 70% to about 100% of the outer surface.
6 . The pull-through applicator of claim 1 , wherein the fibrous applicator body has an outer diameter substantially the same size as a bore of the gun barrel.
7 . The pull-through applicator of claim 6 , wherein the fibrous applicator body is configured to contact rifling defined within the gun barrel.
8 . The pull-through applicator of claim 1 , further comprising a coupling coupled to the second end, wherein the coupling is a fused region of the strands.
9 . The pull-through applicator of claim 1 , wherein the braided cord includes at least one of nylon and rayon.
10 . A kit for maintaining a barrel of a firearm, comprising:
a pull-through applicator including:
a braided cord including strands that are interwoven, and having first and second ends, the braided cord including a first portion and an expanded portion extending from the first portion proximal to the second end, the expanded portion having a diameter larger than a diameter of the first portion and forming a mesh; and
a fibrous applicator body disposed in the expanded portion and surrounded by the mesh, wherein the mesh covers a majority of an outer surface of the fibrous applicator body;
a packet containing a liquid to be applied to the barrel of the firearm; and
instructions including the steps of:
coating at least a portion of the fibrous applicator body with the liquid from the packet; and
pulling the fibrous applicator body through the barrel.
11 . The kit of claim 10 , wherein the liquid is one of a cleaning solvent and a rust inhibitor.
12 . A method of manufacturing a pull-through applicator for maintenance of a gun barrel, comprising:
interweaving strands to form a braided cord having first and second ends, and a first portion proximal to the first end; and
interweaving the strands around a fibrous applicator body to form an expanded portion of the braided cord proximal to the second end, the expanded portion having a diameter larger than a diameter of the first portion and forming a mesh, wherein the mesh covers a majority of an outer surface of the fibrous applicator body.
13 . The method of claim 12 , further comprising, bonding ends of the strands together at the second end.
14 . The method of claim 13 , wherein the bonding includes fusing the strands together using a melting process.
15 . The method of claim 12 , further comprising coupling a polymer guide weight to the first end.
16 . The method of claim 15 , further comprising forming the guide weight from a biodegradable polymer.
17 . The method of claim 12 , further comprising fabricating the braided cord and the fibrous applicator body from biodegradable fibers.
18 . The method of claim 17 , wherein fabricating the fibrous applicator body further includes fabricating the fibrous applicator body using a biodegradable binder.
19 . A pull-through applicator for maintenance of a gun barrel, comprising:
a braided cord including strands that are interwoven, and having first and second ends, the braided cord including a first portion and an expanded portion extending from the first portion proximal to the second end, the expanded portion having a diameter larger than a diameter of the first portion and forming a mesh;
a guide weight coupled to the first end; and
a fibrous applicator body disposed in the expanded portion and surrounded by the mesh, wherein the mesh covers a majority of an outer surface of the fibrous applicator body; and
a coupling disposed at the second end of the braided cord,
wherein:
each of the strands of the braided cord are of a substantially circular cross-section proximal to the fibrous applicator body;
the guide weight encases the strands proximate the first end of the braided cord; and
the coupling secures the strands together at the second end of the braided cord to capture the fibrous applicator body within the mesh.
20 . The pull-through applicator of claim 19 , wherein the braided cord and the fibrous applicator body are biodegradable.
21 . The pull-through applicator of claim 19 , wherein the mesh covers at least 70% of the outer surface of the fibrous applicator body.
22 . The pull-through applicator of claim 19 , wherein the strands are flattened into ribbon form to form the mesh.
