The field of the invention relates generally to an improved apparatus and method for conveniently storing a round of ammunition (aka a “cartridge”) proximate to an unloaded firearm which also provides for quickly accessing and loading the cartridge into a chamber of a firearm barrel, which may be a “tip-up” pistol, or any break-action firearm.
When describing firearms, a “chamber” is the cavity at the rear end of the barrel where a cartridge is inserted before being fired. A chamber must be able to contain the cartridge and resulting pressure when it is fired. A pistol is a type of handgun whose chamber is integral with the barrel. A pistol is distinguishable from other types of handguns such as a revolver, which typically has multiple chambers within a rotating cylinder that is separately aligned with a single barrel. Prior to firing, the cartridge is disposed in the chamber. Generally, the outer diameter of a cartridge is received in a chamber in a close fit between the outside diameter of the cartridge and the inside diameter of the chamber, the goal being to transfer as little energy as possible from the burning gunpowder in the cartridge into expanding the cartridge casing. When a cartridge is fired, a portion of the resulting energy is converted into propelling the bullet in a forward direction down the longitudinal axis of the firearm barrel, and a portion of the resulting energy is converted into kinetic energy into the pistol's spring-loaded slide via blowback gases. This energy forces a pistol's slide to cycle backwards towards the shooter into a rearward position. After the energy of the expanding gases from the burning gunpowder is spent, the slide is motivated forward by a recoil spring that was compressed during rearward cycling of the slide. As the slide is motivated forward, a feature of the slide contacts the uppermost cartridge in a magazine that is disposed in an interior volume of the pistol handle, and features of the slide and firearm guide the uppermost magazine cartridge into the chamber, where the process may be repeated. This process is generally termed “semi-automatic” in the industry.
Generally, a cartridge is initially chambered through manipulating the slide of the gun rearward by a hand of a user. This action is also known as “racking the slide”. However, certain individuals may lack the necessary strength required to rack the slide rearwards against the force of the recoil spring.
The recoil spring's purpose is to absorb the shock when a bullet is fired and return the slide forward causing the next cartridge in a firearm's magazine to be chambered. This cyclical rearward and forward movement of the slide operates to eject the casing of the fired round and reloads the next round into the chamber. Typically, when preparing to fire a semi-automatic pistol, a user must manually load the first cartridge to be fired into the firearm's chamber by racking the slide. After firing the first round, each of the following cartridges are automatically loaded into the chamber by the forward movement of the cycling slide.
In the art there is known a certain type of firearm called a “tip-up” pistol. These pistols provide a solution for individuals who don't have enough strength to rack the slide rearwards against the recoil spring. A tip-up pistol allows the rear of the barrel to swing up and away from the firing pin. The barrel pivots around a hinge set into the firearm's frame near the muzzle. This design allows a cartridge to be manually inserted directly into the chamber of the barrel, rather than fed from a magazine via racking the slide. After a round is manually inserted into the chamber, the barrel is closed into firing position and the firearm is ready to shoot. A major benefit of a tip-up barrel is that a shooter is not required to rack the firearm's slide in order to chamber a first cartridge.
If there is a loaded magazine in a semi-automatic tip-up pistol, then the resulting force of the first shot will blow the spent cartridge casing backwards and out of the gun while also cycling the slide rearwards. The recoil spring will then force the slide forwards and feed the next cartridge in the magazine into the firearm's chamber for subsequent shots.
Many individuals choose to store firearms in their home for defensive purposes. Some individuals may also choose to carry a handgun with them throughout the day. Regardless of where an individual keeps their firearm, there are two common ways of storing a firearm should a defensive need ever arise. The first is always having a cartridge “chambered” in the firearm. The second is keeping the chamber of the firearm empty, but with a loaded magazine nearby or already inserted in the firearm.
There are many arguments both for and against keeping a cartridge always chambered in a firearm. Typically, the arguments center around the need to fire a round as quickly as possible in an emergency versus the chances of negligently discharging a round. People who choose to keep the chamber empty argue that the time saved by carrying a round in the chamber isn't significant enough to make a difference since it generally takes less than a second to rack a slide and begin shooting.
However, this argument is moot when talking about individuals who lack the necessary strength to exert the requisite force needed to rack a slide against the force of a firearm's recoil spring. Thus, there are many individuals who choose to own a break-action type of firearm (e.g. a tip-up pistol). Even though manually loading the first round into the chamber of a tip-up pistol is easy, it generally takes much longer than merely racking the slide of a pistol.
In a defensive situation, an individual carrying an unloaded tip-up pistol is subject to locating a first round to be loaded and correctly orientating the round before manually inserting it into the chamber. The potential for fumbling with the round or even dropping the round on the ground are also an ever-present risk. Once the first round is manually inserted into the chamber of a tip-up pistol, the barrel must be pushed downwards into the frame of the gun to be locked before firing.
What is needed in the art, therefore, is an apparatus and method adapted to help an individual securely carry a round of ammunition in the correct orientation which also provides fast and convenient loading capabilities. Thereby allowing a round to be quickly and manually chambered into an unloaded break-action firearm.
The present invention is an apparatus and method that have one or more of the following features and/or steps, which alone or in any combination may comprise patentable subject matter, and which overcome the aforementioned needs of the art.
In an exemplary embodiment, the present invention is an apparatus for loading a cartridge into a chamber of a firearm. The apparatus may be added to the baseplate of a firearm magazine for securely storing and carrying a single round of ammunition. The apparatus improves the time it takes for an individual to load a round of ammunition into a chamber of a break-action firearm.
In embodiments, the apparatus comprises: a housing having a plunger cavity and a cartridge retaining cavity, the cartridge retaining cavity adapted to receive the chamber of a firearm barrel; a plunger at least partially disposed within the plunger cavity; a spring providing a force on a first surface of the plunger; the plunger translatably attached to said housing, the plunger having a plunger second surface adapted to be in contact with a rear surface of a cartridge to be loaded into a chamber of a firearm; the cartridge retaining cavity adapted to removably retain, or removably attach, a cartridge via a slidable engagement; wherein, when said housing is motivated onto the chamber section of a firearm barrel, a cartridge retained in said cartridge retaining cavity is motivated into the chamber; and wherein when said housing is motivated in a direction F orthogonal to a longitudinal axis L of the firearm chamber, a cartridge that is removably attached to said cartridge retaining cavity is removed from the cartridge retaining cavity, leaving the cartridge disposed in the chamber.
In embodiments, the apparatus comprises: a housing having a plunger cavity and a cartridge retaining cavity for storing a cartridge, wherein the plunger cavity comprises a spring and a plunger at least partially disposed in said plunger cavity, wherein the cartridge retaining cavity includes a track adapted to retain a cartridge, the track sized to fit into, and be received by, an extraction groove of a cartridge in a sliding engagement; and wherein the plunger creates a friction retaining force for holding a rim of a cartridge against the track; and wherein the cartridge retaining cavity is large enough to allow a chamber portion of a firearm barrel to fit inside the cartridge retaining cavity, wherein a cartridges stored in the cartridge retaining cavity is inserted into and received by a chamber of a firearm barrel when the chamber is motivated into the cavity.
In embodiments, a plunger and a spring provides a biasing force on the plunger, the biasing force causing a surface of the plunger to press against the rear face of a cartridge that has been loaded into the apparatus with sufficient force to retain the round of ammunition in the cartridge retaining cavity.
In embodiments, the track may be further defined as a U-shaped track sized to be inserted into, and received by, the extraction groove of a cartridge.

The accompanying drawings, which are incorporated into and form a part of the specification, illustrate one or more embodiments of the present invention and, together with the description, serve to explain the principles of the invention. The drawings are only for the purpose of illustrating exemplary embodiments of the invention and are not to be construed as limiting the invention. In the drawings:
The following documentation provides a detailed description of the invention.
Although a detailed description as provided in this application contains many specifics for the purposes of illustration, anyone of ordinary skill in the art will appreciate that many variations and alterations to the following details are within the scope of the invention. Accordingly, the following preferred embodiments of the invention are set forth without any loss of generality to, and without imposing limitations upon, the claimed invention. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents, and not merely by the preferred examples or embodiments given.
Throughout the specification there are several terms that will be used that are particular to firearms. The terms are to be used in the context of their ordinary and customary meaning as they relate to firearms. Any terms will be specifically defined if meant to depart from their ordinary and customary firearm meaning. For example, a magazine refers to an ammunition storage and feeding device for a repeating firearm. When referring to pistols, magazines are generally considered detachable and are removable from the interior volume of the grip of a pistol. A magazine may be integrated into a firearm or may refer to a detachable type of magazine that may be inserted and removed from the firearm, for example, and not by way of limitation, by insertion of the magazine into a receiving opening in an interior volume of a pistol grip. Removing a magazine from the interior volume of the grip of a pistol is performed by using a magazine release. A magazine release may be a switch, a lever, a button or any other type of release positioned on the frame of a firearm which functions to release a magazine from the interior volume of the grip/frame of a firearm. Pistol magazines generally comprise a shell, a magazine spring, a follower, and a baseplate. Magazine baseplates are a removable bottom piece of the magazine that provides access to a magazine's internal components (magazine spring and follower) for cleaning and maintenance.
A pistol magazine can be loaded and filled with as little or as many rounds as the magazine's capacity allows, usually somewhere between 7 and 20 rounds. But the present invention is not limited to any specific magazine capacity. The number of rounds a magazine may hold depends on the caliber, size of the magazine, and choices of the individual loading the magazine. Still further, contemporary magazines may be a single-stack type or a double-stack type. One of ordinary skill in the art will appreciate that the apparatus of the present invention is configurable to fit any caliber of bullet and any type of magazine.
As used herein, the terms “round”, “round of ammunition”, “ammunition round”, “cartridge”, “cartridge of ammunition” and “ammunition cartridge” may be used interchangeably. For purposes of this specification, the terms refer to a single unit of firearm ammunition consisting of a cylindrical case/casing (typically made of a metal or alloy). The case/casing of a cartridge (or round) serves as the integrating housing for the other functional components (i.e. primer, gunpowder, and bullet). Cartridges are sized to fit the interior chamber of a firearm.
As used herein, the term “caliber” is given its ordinary and customary meaning. Certain embodiments described herein may refer to a particular caliber, but the present invention is not limited to any specific caliber. The invention may be configured to be used with any caliber that is presently available or may become available in the future.
For sake of understanding this specification, it is important to note that a cartridge case/casing is not necessarily a perfect cylinder. Rather, this disclosure will talk about the anatomy of a cartridge case using three distinct terms—the rim 401, extraction groove 402, and the body 403.
The apparatus comprises four main components: a housing 101, a spring 105 having a first end 109 and a second end 110, a plunger 106, and a pin 107. A housing 101 can be made from any metal, polymer, or any other suitable composite or other material, or any combination of the foregoing materials. In embodiments, the housing is constructed as a single piece, which may be done using a mold or 3-D printing. In embodiments, the housing 101 may be manufactured using multiple pieces that are assembled using fasteners, welding, adhesives, or any other means known in the art. The housing 101 can be configured with rails (not shown) on the top portion of the housing which allows for removably attaching the apparatus onto a conventional magazine baseplate without requiring the use of a tool. In embodiments, the housing can be configured to replace the baseplate of a conventional magazine. The process of replacing the baseplate of a conventional magazine is well-known in the art.
The housing 101 has a plunger cavity 104 located in the rear portion of the housing 101 where the spring 105, plunger 106, and pin 107 are all disposed when fully assembled and function together to create a spring-loaded friction retaining force for a cartridge. The plunger 106 may be attached to the housing 101 by insertion of the pin 107 into a pin hole 108 and through a plunger void 202, pin 107 being received by an opening 600 in housing 101, which opening may be a blind opening, thereby creating a translatable attachment.
Still referring to
The cartridge retaining cavity 102 of the housing 101 further comprises an integral “U-shaped” track 103, hereinafter referred to as the “track”. The track 103 functions to receive an extraction groove 402 of a cartridge in a slidable engagement and properly align a cartridge in the cartridge retaining cavity 102 for loading a cartridge into a chamber of a firearm barrel. A feature of the track 103 is the forward tapering that occurs at the bottom of the track. This tapering functions cooperatively with the plunger 106 so that the cartridge is “kicked” forward when released from the track 103 when the housing 101 is motivated in the direction F, orthogonal to the longitudinal axis L of the chamber. This kick forward helps to push the cartridge into a chamber of a barrel when loading the cartridge into a firearm.
Referring to
The design of the plunger lip 203 also facilitates the functioning of the apparatus. This lip 203 functions both to help securely hold a cartridge in place during storage of a cartridge in the apparatus and to assist with the forward kick of the cartridge into the chamber of a barrel as the cartridge is released from the apparatus.
