BACKGROUND OF THE INVENTION
For decades, ammunition cartridges packaged on stripper clips have assisted users in expediting the process for loading ammunition cartridges into magazines. Stripper clips facilitate the bulk loading of cartridges into magazines by keeping cartridges filed in single files which are easy to align with and load into the open ends of magazines. However, most ammunition cartridges available on the commercial market do not come packaged on stripper clips. Commercial ammunition cartridges often come packaged in cartridge carriers such as cardboard boxes and plastic trays which are economic to manufacture and package cartridges in. However, the tradeoff for this economy is the loss of ergonomics in being able to transfer cartridges from packaging into magazines quickly and easily.
In response to the relative difficulty of loading commercial packaged cartridges into magazines, the commercial market has developed an array of speed loading devices to assist users in transferring ammunition packaged in boxes or trays to magazines. However, the majority of these speed loading devices assist users only in pressing ammunition cartridges into magazines, but do not facilitate or speed up the process for transferring ammunition to the magazines. This means that users of current speed loading devices are required to transfer cartridges in boxes or trays onto speed loading devices or magazines by individual cartridges manually by hand. There are currently no devices which can receive ammunition cartridges directly from commercial boxes or trays in bulk for loading into magazines.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The prior art method for loading cartridges stored in an cartridge carrier requires taking out individual cartridges from the cartridge carrier and loading them one by one into a magazine or onto a magazine speed loading device for loading into a magazine. As this is time and labor intensive, it is an object of an embodiment of the present invention to provide a system by which the cartridges contained on an ammunition carrier can be transferred directly from a cartridge carrier such as a box or tray onto a magazine speed loading device in bulk and then loaded into a magazine in bulk.
An example embodiment of the present invention is a process by which the cartridges on a cartridge carrier are placed in bulk onto a speed loading device where they are segregated into multiple groups, aligned into single files in their groups and loaded into a magazine. This process involves the use of multiple parallel partition walls on the speed loading device that move in tandem with one another on the speed loading device. The partition walls have distal narrow sides that couple with a cartridge carrier at a side of the cartridge carrier which exposes the cartridges in the cartridge carrier. The cartridge carrier is coupled to the partition wall distal narrow sides in such a manner that the cartridges on the exposed side of the cartridge carrier face into a receiving surface of the speed loading device. The partition walls segregate and compartmentalize the cartridges on the cartridge carrier into compartment spaces, defined by the partition walls, based on the vertical row configuration the cartridges are arranged in on the cartridge carrier, which is based on the orientation of the cartridge carrier to the partition walls. Opposite to the distal narrow sides are a set of proximal narrow sides on the partition walls which are slideably engaged with the receiving surface. The receiving surface is a generally elongated surface on the speed loading device that runs the length of the speed loading device and has two long edges and two short edges. The receiving surface is configured to receive and support cartridges displaced from the cartridge carrier, coupled to the partition wall distal narrow sides, by force of gravity. The receiving surface is also configured receive and support individual cartridges placed onto the receiving surface by hand. The cartridges displaced onto the receiving surface from the cartridge carrier are partially retained within the cartridge carrier while the cartridge carrier is coupled to the partition wall distal narrow sides. Upon decoupling of the cartridge carrier from the partition wall distal narrow sides and removing the cartridge carrier from tangency with the cartridges, cartridges gain the ability to move parallel to the length of the receiving surface on the receiving surface.
A proximal long edge on the receiving surface is coupled to an alignment wall running the length of the speed loading device. The alignment wall is configured to work in conjunction with the partition walls in successively leveling each group of cartridges segregated by the partition walls and displaced onto the receiving surface into single file rows which are parallel and adjacent with the alignment wall. Each partition wall successively urges the group of cartridges that is adjacent to it, that lies between it and the alignment wall, against the alignment wall and forms a temporary chamber with the alignment wall that is the width of a cartridge.
A magazine is engaged to the speed loading device at a proximal short edge of the receiving surface, located adjacent to the proximal long edge, in such a manner that the open end of the magazine is aligned with the successive files of cartridges aligned in the temporary chambers formed by the alignment wall and each of the partition walls. A loading rod, which is a generally elongate rectangular bar, is slideably engaged with the receiving surface at the distal short edge of the receiving surface, located opposite to the proximal short edge. The loading rod is configured to slide the length of the receiving surface, from the distal short edge to the proximal short edge, while in tangency with the alignment wall. The loading rod successively urges each successively filed group of cartridges in each successively formed chamber from the receiving surface into the open end of the coupled magazine. After each successive urging, the loading rod is withdrawn from the receiving surface and the partition wall that formed a chamber for the prior group of cartridges that have been urged from the receiving surface is urged through the alignment wall through an opening in the alignment wall. This allows a successive group of cartridges, following the prior cartridges, to be leveled against the alignment wall by urging of the partition wall that is adjacent to the successive cartridges, which has not been urged through the opening in alignment wall. As this and each subsequent partition wall forms a chamber with the alignment wall, the loading rod is continually reengaged with the receiving surface and urges cartridges into the open end of the coupled magazine until all cartridges on the receiving channel are urged from the receiving surface.
In reference to example embodiments disclosed in FIGS. 1A and 1B, a cartridge carrier 101 is a generally elongated rectangular box shaped container, also known as a box or tray, containing a single or multiple exposed holding compartments 102. Ammunition cartridges 100 are placed into the holding compartments 102 with either the bullet tips 103 or flat primer sides 104 placed foremost into the holding compartments 102. In one embodiment of the cartridge carrier 101, cartridge carriers 101 have a single row of multiple holding compartments 102. In another embodiment of the cartridge carrier 101, cartridge carriers 101 have a single holding compartment 102 which can host a single row of cartridges 100. In another embodiment of the cartridge carrier 101, cartridge carriers 101 have a single holding compartment 102 which can host multiple rows of cartridges 101. In another embodiment of the cartridge carrier 101, cartridge carriers 101 have multiple rows of holding compartments 102 arranged adjacent and parallel to one another with cartridges 100 placed into the holding compartments 102, cartridge bullet tips 103 inserted foremost into the holding compartment 102.
In reference to example embodiments disclosed in FIGS. 2A and 2B, the speed loading device 200 is a generally elongated rectangular box shaped container which defines a receiving surface 201 that runs the length of the speed loading device 200 on a side of the speed loading device 200. The receiving surface 201 has a proximal short edge 202 located on a short edge, a distal short edge 213 located opposite to the proximal short edge 202, an adjacent long edge 215 located between the proximal short edge 202 and distal short edge 213, and an opposite long edge 216 located opposite of the adjacent long edge 215. The receiving surface 201 is configured to slideably engage with cartridges 100 placed onto it by loose individual cartridge 100 or placed onto it in bulk from a cartridge carrier 101, and guide cartridges 100 to the proximal short edge 202, which is configured to host the open end of a magazine 300. The speed loading device 200 further defines multiple partition walls 203 which have multiple proximal narrow sides 204 that are slideably engaged with the receiving surface 201. The partition walls 203 move laterally along the receiving surface 201 along the width of the speed loading device 200 while moving in tandem with one another. The partition walls 203, running parallel to one another, also run parallel to the length of the speed loading device 200 and are elongated perpendicularly to the receiving surface 201. The partition walls 203 are configured to segregate and compartmentalize the surface area of the receiving surface 201 into compartment spaces 206 defined by the partition walls 203. In an embodiment, the partition walls 203 consist of two sets of walls. The compartment spaces 206 on the partition walls 203 run the length of the partition walls 203 and in an embodiment segregate and maintain cartridges 100 in a single row configuration. In another embodiment, the compartment spaces 206 segregate and maintain cartridges in multiple parallel offset rows. The partition walls 203 are further configured to control the lateral movement of cartridges 100 placed onto the receiving surface 201 by manipulating the positioning of the compartment spaces 206 on the receiving surface 201. The partition walls 203 further define distal narrow sides 205 located opposite to the proximal narrow sides 204 which are configured to couple with cartridge carriers 101 and segregate cartridges 100 on the cartridge carriers 101 into the partition wall compartment spaces 206 based on the vertical row configuration cartridges 100 are arranged in on the cartridge carrier 101, which is dependent on the orientation of the cartridge carrier 101 to the partition wall distal narrow sides 205. The distal narrow sides 205 define tapers 207 on the distal narrow sides 205 which assist in segregating cartridges 100 on a cartridge carrier 101 into the partition wall compartment spaces 206. The distance between the distal narrow sides 205 and the receiving surface 201 is configured to allow cartridges 100 on a cartridge carrier 101 coupled to the distal narrow sides 205 to move out from the cartridge carrier 101 into tangency with the receiving surface 201 while maintaining their bullet tips 103 or flat primer sides 104 in the cartridge carrier 101. The speed loading device 200 further defines an alignment wall 208 which runs parallel to the length of the speed loading device 200 throughout the length of the speed loading device 200. The alignment wall 208 is elongated perpendicularly to the receiving surface 201 and is coupled to the receiving surface 201 at the adjacent long edge 215. The alignment wall 208 is adjacent to the partition walls 203 and runs parallel to the partition walls 203. The alignment wall 208 defines an alignment surface 209 on a side of the alignment wall 208 facing toward the partition walls 203 which is configured level cartridges 100 urged against it by partition walls 203 into single file rows. The alignment wall 208 further defines a passage opening 210 located on the alignment surface 209 which runs through the alignment wall 208 that is configured to allow the passage of the partition walls 203 through the alignment wall 208. The speed loading device 200 further defines an obstructing wall 211 coupled to the receiving surface 201, at the receiving surface proximal short edge 202, which is elongated perpendicularly to the receiving surface 201. The obstructing wall 211 runs perpendicular to the alignment wall 208 and parallel to the width of the speed loading device 200 from the receiving surface opposite long edge 216 to a cartridge width away from the alignment surface 209. This cartridge wide gap 217 between the alignment surface 209 and the obstructing wall 211 is configured to allow passage of cartridges 100 from the receiving surface 201 to the receiving surface proximal short edge 202. The obstructing wall 211 is configured to maintain cartridges 100 on the receiving surface 201 when the speed loading device 200 is angled diagonal to the ground 400 with the receiving surface distal short edge 213 elevated above the receiving surface proximal short edge 202. The speed loading device 200 further defines a loading rod 212, which is a generally elongated rectangular bar that is sufficient in length to reach from the receiving surface distal short edge 213 to the receiving surface proximal short edge 202. The loading rod 212 defines a sliding surface 214, located on a long side of the loading rod 212, which is slideably engaged with the receiving surface 201 at the receiving surface distal short edge 213. The loading rod 212 defines an urging surface 218, located on a proximal long end of the loading rod 212, configured to travel adjacent to the alignment surface 209 and urge single filed cartridges 100 on the receiving surface 201 adjacent to the alignment surface 209 from the receiving surface 201 into the open end of a magazine 300 coupled to the receiving surface proximal short edge 202.
In reference to example embodiments disclosed in FIG. 3, the open end of a magazine 300 is engaged with the speed loading device 200 at the receiving surface proximal short edge 202 in such a manner that the open end of the magazine 300 is adjacent to and parallel with the alignment surface 209 while aligned with the cartridge wide gap 217. The length of the speed loading device 200 is angled perpendicular to the ground 400 and a cartridge 100 bearing cartridge carrier 101, also with its length perpendicular to the ground, is coupled to the distal narrow sides 205 of the partition walls 203 at the side of the cartridge carrier 101 bearing the holding compartments 102. The distal narrow sides 205 is coupled with the cartridge carrier 101 in such a manner that cartridges 100 exposed in the holding compartments 102 of the cartridge 101 are facing toward the receiving surface 201, the cartridge flat primer sides 104 facing foremost toward the receiving surface 201. The cartridges 100, when coming into adjacency with the partition walls 203, are segregated and compartmentalized by the partition walls 203 into each of the compartment spaces 206 of the partition walls 203 according to the vertical rows in which cartridges 100 are arranged in on the cartridge carrier 102.
In reference to example embodiments disclosed in FIG. 4, the speed loading device 200 and cartridge carrier 101 are tilted to be parallel or diagonal to the ground 400 with the cartridge carrier 101 placed over the speed loading device 200 in order to shift the support of the cartridges 100 from the cartridge carrier 101 to the speed loading device 200 by force of gravity. Cartridges 100 slide partially out from the holding compartments 106 of the cartridge carrier 101 and the flat primer sides 104 of the cartridges 100 come into contact with the receiving surface 201. As support of the cartridges 100 shifts from the cartridge carrier 100 onto the receiving surface 201, the bullet tips 103 of the cartridges 100 are still maintained in the cartridge carrier 101. The speed loading device 200 and cartridge carrier 101 are tilted so the distal short edge 213 of the receiving surface 201 is elevated over the proximal short edge 202, with the cartridge carrier 101 over the speed loading device 200, to influence the flat primer sides 104 of cartridges 100 to lean toward the receiving surface proximal short edge 202. This allows cartridges 100 to move on the receiving surface 201 in the direction of the receiving surface proximal short edge 202 with a lower likelihood of the lengths of cartridges 100 pitching to become parallel with the length of the speed loading device 200.
In reference to example embodiments disclosed in FIG. 5, the cartridge carrier 101 is decoupled from the distal narrow sides 205 of the partition walls 203 and from the cartridges 100 and is lifted from tangency with the distal narrow sides 205 and the cartridges 100. By force of gravity, cartridges 100 move in tangency with the receiving surface 201 toward the receiving surface proximal short edge 202 until coming into contact with the obstructing wall 211 or the open end of the magazine 300 coupled to the receiving surface proximal short edge 202. In an embodiment, the cartridges 100 compartmentalized in the compartment spaces 206 are held in single files per compartment space 206. In another embodiment, the cartridges 100 compartmentalized in the compartment spaces 206 are held in dual parallel offset rows per compartment space 206.
In reference to example embodiments disclosed in FIGS. 6A and 6B, cartridges 100 held in the compartment space 206 immediately adjacent to the alignment surface 209 of the alignment wall 208 are urged against the alignment surface 209 by urging the partition walls 203 toward the alignment surface 209. These cartridges 100, being urged against the alignment surface 209 by a partition wall 203 immediately adjacent to the cartridges 100, become level with the alignment surface 209 and form a single file row that is parallel with the length of the alignment surface 209 and aligned with the cartridge wide gap 217. The partition wall 203 immediately adjacent to the single filed cartridges 100 works in conjunction with the alignment surface 209 in forming a loading chamber one cartridge width wide that facilitates the urging and directing of cartridges 100 from the receiving surface 201 through the cartridge wide gap 217 into the open end of the magazine 300 by the pressing rod 212. The sliding surface 214 of the loading rod 212 is slideably engaged with the receiving surface 201 at the receiving surface distal short edge 213 with the urging surface 218 of the pressing rod 212 facing toward the receiving surface proximal short edge 202. The urging surface 218 is slid away from the receiving surface distal short edge 213 toward the receiving surface proximal short edge 202 and comes into contact with the top cartridge 105 of the single filed cartridges 100 adjacent to the alignment surface 209. The urging surface 218 urges the top cartridge 105, which in turn urges the entire file of cartridges 100 adjacent to the alignment surface 209, through the cartridge wide gap 217 into the open end of the magazine 300. The loading rod 212 is then retracted back to the receiving surface distal short edge 213 and the loading rod sliding surface 214 is disengaged from the receiving surface 201.
In reference to example embodiments disclosed in FIG. 7, the partition wall 203 that was immediately adjacent to the file of cartridges 100 urged into the open end of the magazine 300 is urged through the passage opening 210 of the alignment wall 208 and the next successive compartment space 206 with cartridges 100 is brought into adjacency with the alignment surface 209. The cartridges 100 in the successive compartment space 206 are urged against the alignment surface 209 by the partition wall 203 immediately adjacent to the cartridges 100, which has not been passed through the alignment wall 208, and become leveled with the alignment surface 209 into a single file row aligned with the cartridge wide gap 217. The immediately adjacent partition wall 203, which has not been passed through the alignment wall 208, works in conjunction with the alignment surface 209 in forming a loading chamber one cartridge width wide that facilitates the urging and directing of cartridges 100 adjacent to the alignment surface 209 through the cartridge wide gap 217 into the open end of the magazine 300. The sliding surface 214 of the loading rod 212 is slideably engaged with the receiving surface 201 at the receiving surface distal short edge 213 with the urging surface 218 of the receiving surface 201 facing toward the receiving surface proximal short edge 202. The urging surface 218 is slid from the receiving surface distal short edge 213 toward the receiving surface proximal short edge 202 and comes into contact with the top cartridge 105 of the single filed cartridges 100 adjacent to the alignment surface 209. The urging surface 218 urges the top cartridge 105, which in turn urges the entire file of cartridges 100 adjacent to the alignment surface 209, through the cartridge wide gap 217 into the open end of the magazine 300.
