Cap for attachment to a barrel end and storage means therefor

Abstract

A convex cap (1) for removable attachment to a barrel (2) end of projectile (3) firing equipment such as the end of a gun barrel (2), purposed to protect the interior of the projectile (3) firing equipment from foreign matter such as dust, dirt, debris and moisture wherein the cap (1) is adapted to be in place on the barrel (2) end at the time of firing. A means of storing caps is also provided.

Description

BACKGROUND OF THE INVENTION [0001] The present invention generally relates to the field of weaponry and more specifically to a means of protecting the interior of projectile firing equipment, including the barrel, from foreign matter such as dust, dirt, debris and moisture including that in the form of rain and snow. [0002] It is known in the art that debris and moisture in the barrel or other interior portions of projectile firing equipment can lead to malfunction thereof and / or physical and / or chemical degradation including corrosion. Furthermore, if firing equipment becomes plugged it may become susceptible to exploding. [0003] Other caps have been disclosed in the art such as in U.S. Pat. No. 3,455,047 entitled “Muzzle Patch For Firearms” issued to Hoag on Jul. 15, 1969. Hoag describes an adhesive patch which is pressed onto the tip of a muzzle of a gun to prevent dust and moisture from entering the barrel of the gun. The patch is made of a suitable plastic such as the material ...

AI Technical Summary

Benefits of technology

[0004] According to an aspect of the present invention there is provided a cap for removable attachment to a barrel end of projectile firing equipment which allows substantially unaffected firing of the projectile firing equipment, wherein the barrel end is perpendicular to a direction of firing of the projectile firing equipment, characterized by a central convex portion which covers an aperture of the barrel end; and a peripheral edge portion joined peripherally to the central convex portion and adapted to be removably attached, via an attachment means, to the barrel end and having a substantially similar form as the barrel end.

[0006] The cap is of convex form which allows the cap to be effectively blown off the barrel upon firing. In contrast, a flat surface may blow off only in part leaving a portion attached to the barrel. The weight of the cap and the attachment characteristics ensure that the cap will not, to any substantial degree, affect the trajectory of the projectile.

Problems solved by technology

It is known in the art that debris and moisture in the barrel or other interior portions of projectile firing equipment can lead to malfunction thereof and / or physical and / or chemical degradation including corrosion.

Furthermore, if firing equipment becomes plugged it may become susceptible to exploding.
