Patent Application
20220107158
The present disclosure relates to the field of accessories for use with a muzzle-loading firearm. The disclosure relates to a holder for a primer that affixes to a location on the body of a muzzle-loading firearm and retains the primer through magnetic attraction. The primer holder prevents loss of the primer and allows for a safe and efficient means of storing a primer for quick retrieval.
A more efficient means of storing primers for muzzle-loading firearms is needed, particularly for the fields of sport hunting or big game hunting that is often conducted in difficult terrain or adverse weather conditions, such as extremely cold and/or wet conditions. Most official deer hunting seasons in the United States begin in or around mid-October and last through December. Current technology does not allow for the storage of a primer at multiple locations on the body of a firearm. There is a need for a means of storing a primer within close proximity of the place of use on the firearm, that allows for quick retrieval, and that does not interfere with the functionality of the firearm.
A muzzle-loading firearm, also known as a muzzleloader, is an open system firearm in which the propellant and projectile are loaded from the muzzle end of the rifle. An open system firearm has an opening at both ends, such as the nipple, or touch hole and the muzzle. Inline muzzleloaders are a modern type of muzzle-loading firearm with an ignition system that uses a breech plug that places a shotgun primer directly in line behind the main propellant charge.
A primer initiates the propellant combustion that will push a projectile, or bullet, out of a gun barrel. Primers called “209 primers” are frequently used with modern in-line 0.50-caliber models of muzzleloaders that are designed for use with 209 shotgun primers.
A 209 primer is small in size, measuring approximately 0.3 inches in length and just under 0.25 inches in diameter.
Due to its small size, a primer is easy to lose. Further, the small size of the primer, as well as the adverse weather conditions that can occur during hunting, frequently make it difficult for a firearm operator to retrieve a primer quickly and insert the primer in the breech of a muzzleloader. For example, if an operator keeps a primer in a clothing pocket and attempts to retrieve the primer in freezing weather with cold hands, there is a high likelihood of loss of the primer. As a result of this type of concern, operators frequently do not remove the primer from the breech of the firearm which is unsafe. Thus, there is a need for an integrated primer holding device that provides ready availability of the primer and is a safer alternative to keeping the primer in the firearm after use.
Existing technology is limited for securing a primer to the outside of a muzzleloader. For example, U.S. Pat. No. 5,544,441 teaches a spare primer holder that uses friction of rubber material to hold the primers to the scope of a rifle only rather than a primer holder that is capable of being affixed to other locations on the body of a muzzleloader at the option of an operator. Further, U.S. Pat. No. 5,544,441 teaches a design that is open to the elements and does not keep primers dry, which negatively affects the performance of a primer. U.S. Patent Application Number 2008/0092420 teaches a magnet that simply holds the primer in the breech, or firing position, of a firearm and does not allow for placement on other surfaces of the firearm at the option of the operator.
Thus, current technology does not allow an operator to easily remove a primer from a holder while also protecting the primer's optimal functionality.
The present invention will provide a device that will allow the operator of a muzzle-loading firearm to safely and efficiently hold a primer on the body of the firearm.
The invention disclosed herein relates to a device used to hold a primer at a location chosen by the operator on the body of a muzzle-loading firearm, allowing for safe storage and quick removal.
In a first aspect, the invention is circular shaped magnet disc of approximately ⅛ inch thickness and a diameter greater than the standard 0.241 inch diameter of a 209 primer and with the magnet having a bottom surface covered in a self-adhesive layer and having a top surface capable of holding a primer on the vertical axis by magnetic attraction.
A second aspect involves affixing a hollow, cylindrical body to the top surface of the magnet and with the cylindrical body having an inner diameter that is greater than the standard 0.241 inch diameter of a 209 primer and a height less than the standard 0.30 inch height of a 209 primer. The cylindrical body prevents removal of the primer from the magnet along the horizontal axis.
A third aspect involves affixing a layer of a moisture-sealing elastomeric material to the top surface of the magnet and with the primer held on the vertical axis to the top surface of the layer of elastomeric material by magnetic attraction. The elastomeric layer seals the primer from moisture.
A fourth aspect involves affixing a metal layer to the bottom surface of the magnet and incorporating the metal layer into the frame of a firearm through adhesive or welding means.
Terms used in this application are defined below.
Muzzle-loading firearm: Also known as a muzzleloader and is an open system firearm in which the propellant and projectile are loaded from the muzzle end of the rifle. An open system firearm has an opening at both ends, such as the nipple, or touch hole and the muzzle.
Inline muzzleloader: Inline muzzleloaders are a modern type of muzzle-loading firearm with an ignition system that uses a breech plug that places a shotgun primer directly in line behind the main propellant charge.
Primer: A primer initiates the propellant combustion that will push a projectile, or bullet, out of a gun barrel.
209 Primer: A type of primer frequently used with modern inline 0.50-caliber models of muzzleloaders that are designed for use with 209 shotgun primers
Breech: Rear end of the barrel of a firearm.
Forearm: Front portion of the stock of a firearm that extends under the barrel in front of the receiver, the metal housing for the working parts of the action, and usually held by the non-trigger hand to help support the firearm.
Scope: A telescopic sight, commonly called a scope, is an optical sighting device that is based on a refracting telescope. Telescopic sights are used with all types of systems that require accurate aiming but are most commonly found on firearms, particularly rifles.
Stock: Handle of a firearm.
All other terms not defined in this specification are given their usual and customary definitions as used by one of ordinary skill in the field.
The present disclosure describes and claims a device for the efficient holding of a primer to the body of a muzzle-loading firearm.
The device can be an aftermarket improvement for a muzzle-loading firearm or it can be factory installed.
The invention allows for the operator of a muzzle-loading firearm to quickly retrieve and safely store a primer. This is advantageous when, for example, the firearm operator is hunting in cold weather or other adverse conditions. Due to its small size, a primer is easy to lose.
In one application, the device is a circular shaped magnet disc of approximately ⅛ inch thickness and a diameter greater than the diameter of a primer and with the magnet having a bottom surface covered in a self-adhesive layer and having a top surface capable of holding a primer on the vertical axis by magnetic attraction.
In another application, a hollow, cylindrical body is affixed to the top surface of the magnet and with the cylindrical body having an inner diameter that is greater than the standard 0.241 inch diameter of a 209 primer and a height less than the standard 0.30 inch height of a 209 primer. The cylindrical body prevents removal of the primer from the magnet along the horizontal axis. The cylindrical body may be made of plastic.
In a third application, a layer of a moisture-sealing elastomeric material is affixed to the top surface of the magnet and with the primer held on the vertical axis to the top surface of the layer of elastomeric material by magnetic attraction. The elastomeric layer seals the primer from moisture. The elastomeric layer may be rubber.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention.
