The present invention is directed to a firearm magazine loading system.
The present invention is in the technical field of firearms. More particularly, the present invention is in the technical field of loading devices for firearms that have a detachable magazine.
Conventional loading of detachable firearm magazines, sometimes incorrectly referred to as clips often require strength, dexterity, or both. It is often difficult to load more than a few magazines at a time by hand, because it often leads to sore fingers. Even currently available magazine “speed” loaders often require dexterity to line up the cartridges one by one in a machine, to then have to force the cartridges into the magazine by either pushing directly down, pulling on a handle to force the cartridges into the magazine, or to insert each cartridge into a finger operated machine one at a time to use leverage to help force them into the magazine. It is often a time consuming and tiring event to line up and then force the cartridges into the magazine either by hand or with mechanical advantage. Often this leads to many people who may suffer from strength or dexterity issues from being able to enjoy the sport of shooting. Further even able-bodied people may avoid this recreational activity due to the time and hassle that is required to load enough removable magazines to make the experience worthwhile.
Applicant's apparatus includes a funnel-like upper portion which can be used for multiple calibers of cartridges, a cassette which attaches to specific caliber magazines and to the funnel, a slider for controlling the follow of cartridges into a magazine, and an attachment to the bottom of conventional magazines comprising a motor and associated parts that retract a spring and carrier plate of the magazine to allow the cartridges to load into the magazine. In certain embodiments, Applicant's apparatus further comprises a stand to hold the entire assembly in a vertical position.

Fins 3 are configured in an alternating pattern, and are constructed such that they are attached to the inside of the guide box 4 at an angle that allows velocity of the falling cartridges to be slowed, and also for the cartridges to move through the guide box without interruption or blockage. In certain embodiments, fins 3 are also smoothly tapered upward towards the front side of the guide box 4 to keep the cartridges in a horizontal position, and to stop them from going into a vertical position due to the nose of the cartridges being substantially heavier than the cartridge casings.
Funnel 1 is attached to and kept in a substantially vertical position by the stand 29 with the use of connectors 28, 38, 39, 40, which slide onto the adjustable arms 57, 58 shown in

Cassette 7 portion of the magazine-loading apparatus 37 comprises a main body 42 comprising a rectangular box with the top and bottom open forming a channel through the main body 42 which the firearm cartridges can progress through. Inside of the main body 42 is a fin 8, which acts in the same way as the fin 3 in
Furthermore, inside of the channel in the main body 42, are four cartridge retainers 11, 43, 44, 45. In certain embodiments, cartridge retainers 11, 43, 44, 45 are made of spring steel, and are attached to the walls of the main body 42 only at the top of the cartridge retainers 11, 43, 44, 45. In certain embodiments, the spring steel is tensioned such that cartridge retainers 11, 43, 44, 45, are aligned in a vertical position, with the exception of the V shaped turn up at the bottom end. The functioning of the cartridge retainers 11, 43, 44, 45 is described hereinbelow.
Cartridges are further guided into their final position through the use of smoothly tapered shims 13 and 14, which are attached to the front and back of the channel through the main body 42. The profiles of shims 13 and 14 can be optimized to guide different caliber cartridges into position. In certain embodiments, additional shims (not incorporated in the drawings) are placed on the left and right side of the channel with the same properties as the shims 13 and 14. In certain embodiments, shims 13 and 14 can be modified to allow attachment of different types of magazines. As shown in

The existing carrier plate 55, which sits on top of the magazine spring (not shown) within the magazine 22, is modified to include an attachment pin 18. This attachment pin 18 is placed at such a point that when force is applied to pull it and the earlier plate 55 down, the assembly is balanced and able to move downwardly within the magazine 22. The bottom of the attachment pin 18 is constructed such that it connects to a pull string 19, which is of sufficient strength to not break due to the force of pulling the magazine spring (not shown) down.
Pull string 19 is routed such that it is connected to the attachment pin 18, at its top, and routed down through a grommet 26, and on to a pulley 24. The grommet 26 is installed in a hole that is placed within the existing bottom plate 56 of the magazine 22. The grommet 26 is positioned such that when the carrier plate 55 is fully retracted the attachment pin 18 aligns directly above the grommet 26, so as not to allow the string 19 to bind up.
Retraction assembly 17 is attached to the bottom of the magazine 22. The retraction assembly 17 is constructed to be as wide and deep as the magazine 22, and is as high as is required to house a high torque electric motor 21, a compartment to house a battery 23, and the accompanying equipment to perform its required task.
In certain embodiments, retraction assembly 17 comprises a high torque electric motor 21, which is configured to wind the string 19 onto the pulley 24 while retracting the magazine spring (not shown). On the opposite side of the pulley 24 from the electric motor 21, there is attached a coil spring 25. This spring 25 is used to keep tension on the string 19, after the electric motor 21 shuts off.
A power button 20 allows the user to trigger the electric motor 21 on and off. Additionally there is a cut off switch 27, which like the string 19 runs through the bottom plate 56 of the magazine 22. The cut off switch 27 halts the power to the electric motor 21 when it pulls the carrier plate 55 to the bottom of the magazine 22. Additionally, in the event that the battery no longer functions, the entire retraction assembly 17 can be used as a handle, and thus the carrier plate 55 can be retracted manually, allowing the invention to continue to be used even without electric power. In the event that this option is used the cut off switch 27 acts as an alignment pin for repositioning the retraction assembly 17.

The bottom plate is replaced by interlocking plates 192. These plates are configured such that they have offset aligned holes and slots that allows for a metal nub 1930 at the end of the metal pull line to go through the holes and the line to slide through the slots. The bottom plates then slide onto and lock in place on the existing magazine.
The metal nub at the bottom of the line has a corresponding detachable handle that is used to lock onto the nub and pull the top plate down.

Holding fork 30 comprises two arms 57 and 58. In certain embodiments, arms 57 and 58 are adjustable, side to side. The arms 57 and 58 are used with connectors 28, 38, 39, and 40 on the funnel 1. Arms 57 and 58 slide into the connectors 28, 38, 39, and 40, and maintain the positioning of magazine-loading device 37.
Legs 32 and 60 are positioned to hold the stand 29 and the magazine-loading device 37. In certain embodiments, rubberized bump pads 33 and 59 are disposed at the end of each of the legs 32 and 60, respectively. Rubberized bump pads 33 and 59 are used to tap the back of a freshly loaded magazine 22 thereon, and thus seat the cartridges 54 to the back of the magazine to allow for more consistent loading into the chamber of a firearm by the bolt.
The advantages of the present invention include, without limitation, the device allows a person to reload a magazine in only a few seconds as compared to others that may take minutes. This device also allows for even people that may have problems with the dexterity of their fingers or hands to enjoy sport shooting. Further, it is portable and easy to transport. It is easy to move this device into a house, a vehicle, or a shooting range because it is relatively small and lightweight. Moving such devices typically requires a single person, and typically at most two if the device is moved in its constituent parts rather than as a whole.
In broad embodiment, the present invention is a system of a funnel, which can interchangeably connect to existing firearm magazines of different caliber with a motorized or manual addition to the end that pulls down the internals of the magazine and allows for the reloading of cartridges.

Assembly 1800 comprises three slides 1810, 1820, and 1820, a rotator 1820 that only allows one shell at a time to fall through the aligner (this is so two shells will not interfere with one another on the way through), and an adjustment plate 1850 that allows the entire assembly to move back and forth above the funnel and allows for different caliber shells to be used.
Cartridges are dropped one at a time onto slide 1810, where they fall down into the rotator 1820. In certain embodiments, rotator 1820 is operated manually. In certain embodiments, rotator 1820 is operated by a motor. The cartridge then falls onto slide 1830. The top portion of slide 1830 comprises friction plate 1860. Friction plate 1860 comprises a rough surface wherein the heavier tip of the shell is held in place by the force of friction while the cartridge casing spins around to be aligned. The cartridge then continues to slide down to the end of slide 1830.
The end of slide 1830 is formed to include a V or U shape cut to align the cartridges in the event that they go past the friction plate without being aligned correctly. In the event that a heavier bullet end of the cartridge is sliding down first (misaligned), with the V shaped grove the force of gravity pulls the bullet down and makes the shell flip over as it falls down onto slide 1840. If on the other hand the cartridge is properly aligned, with the casing of the cartridge falling down first, the heavier bullet will not allow the cartridge to flip over since it is still being held up on slide 1830, thus it will fall directly onto slide 1840 correctly aligned.
There is also an addition to the bottom of slide 1830 which stops the cartridges from bucking up and accidentally flipping over. From there, whether or not it flipped over from slide 1830 the cartridge will simply slip down slide 1840 and into the funnel portion.
While the preferred embodiments of the present invention have been illustrated in detail, it should be apparent that modifications and adaptations to those embodiments may occur to one skilled in the art without departing from the scope of the present invention as set forth herein.
