Device for Organizing, Conveying and Placing Ammunition Cases

Abstract

A device for organizing, conveying and placing ammunition cases consists of a module with an array of funnels on the top face. When cases are poured onto the top face the funnels direct the cases into bores below, generally with the heavy end (rim and extractor groove end) down. Edges of apertures in a plate which slides in a slot in the bottom of the module engage the extractor groove in each case and secure the cases between the plate and module with spring pressure. After securing the cases they may be conveyed to another location at which point the spring may be compressed to release the cases leaving them arranged neatly. A tray is used to contain and interface with a plurality of modules. By adjusting wedges in the tray, the plates in the module assemblies engaged by the wedges are caused to operate as described previously.

Claims

1. A module assembly comprising in combination: a module which contains an array of funnels on the upper horizontal face which direct ammunition cases to fall into bores as they are poured onto the module; a slot at the bottom of the module which holds a plate that is caused to move back and forth within the slot to capture or release said ammunition cases; an array of apertures within said plate at same pattern and spacing as said bores; edges within said apertures which engage the extractor groove in ammunition cases; a spring which holds the plate in the engaged position while said assembly is at rest to capture the cases until such time as the user intervenes; the same spring which also may be compressed by the user to change the position of the plate to the release (open) position thereby generally aligning apertures in the plate with the bores and causing cases to be released from the assembly.

2. A module assembly according to claim 1 wherein the assembly may be shaken with a horizontal back-and-forth movement that induces cases which have been poured onto the upper horizontal face to fall, with the aid of the force of gravity, generally heavy-end down into the funnels and subsequently proceed into the bores in the same orientation.

3. A module assembly according to claim 1 where the standard plate design as described may be replaced with a different plate design depending on the ammunition case type or function desired of the module assembly, for example, a plate with aperture edges not designed to engage extractor grooves in ammunition cases but instead designed to stop a case or assembled ammunition cartridge from falling through the bores until such time as the user desires to release the contents of the assembly over a secondary receptacle, for example, a storage or packing box.

4. A module assembly according to claim 1 where the module and plate are made of plastic in the preferred embodiment but may be made of any suitable rigid or semi-rigid material.

5. A tray comprising in combination: a depressed area into which a plurality of module assemblies described in claim 1 may be inserted; a flat horizontal surface at the bottom of the depressed area; mechanisms in the sides of said tray which interface with the plates in the inserted module assemblies by applying pressure to the plates to hold them in the release (open) position or alternatively disengaging the plates to leave them in the capture position, which is the at-rest position; angled sides of said tray which extend above the top surface of the module assemblies to act as a partial perimeter to contain cases as they are poured over the module assemblies; an overflow lip aligned with the top of the module assemblies which allows extra cases to be swept off the top surface of the module assemblies after bores have been occupied.

6. A tray according to claim 5 which is not necessary to the function of the module assemblies described in claim 1 but provides a means by which the user may hold the module assembly plates in the release (open) position.

7. A tray according to claim 5 in which the mechanisms in the side of the tray are wedges which, when slid back and forth, apply pressure to the plates by causing them to be moved in the perpendicular direction of the wedge motion by the inclined ramp of the wedge.

8. A tray according to claim 5 which has a screen as the horizontal surface at the bottom of the depressed area, supported by an open substructure which together allows liquid to flow through the tray.

9. A tray according to claim 5 on which a funnel-shaped end piece is attached on the overflow lip end which prevents cases from falling off the overflow lip end as the tray is agitated, and also serves to direct extra cases into a container when they are swept off the overflow lip end.

DETAILED DESCRIPTION

[0021] Referring to the drawings there is shown generally, as indicated by reference numeral 16, a module with a plurality of funnels 21 in the top face, with the top of the funnels 21 having a square shape and the bottom of the funnels 21 having a round shape with size proportionate to the caliber of case 23 being organized. The form of the funnel 21 transitions smoothly from the square shape at top to the round shape at bottom.

[0022] Below each funnel 21 is a bore 22 which extends through the module 16 vertically. The vertical height of the bottom of the module 16 to the top of the funnel 21 is approximately equal to the height of the type of case 23 being organized. Because the top of the case 23 is substantially aligned with the top of the module 16, this allows excess cases to be swept off the top face of the module when the cases 23 have occupied the bores 22. Height of the module 16 will vary depending on what size of case 23 is being organized. Also height may adjusted in an alternative embodiment to where the bore 22 height is minimized so that more of the case 23 is exposed for better visual inspection of cases 23, but not less than what is needed to provide proper capture function of the module assembly 15. This inspection embodiment as described will not function as well for sweeping extra cases 23 from the top face of the module 16. Center-to-center distance of bores 22 also will depend on size of case 23 being organized. In the case of the embodiment shown in the drawings, the case 23 type is .45 caliber ACP and the center-to-center distance between bores 22 is 0.75 inches. Bore 22 diameter corresponding to the .45 ACP case is 0.53 inches. Other popular cartridge cases 23 for which corresponding modules 16 and plates 17 may be made include, but are not limited to, 9 mm, 10 mm, .40 S&W, .32 ACP, .38 Super, .357 Sig, and .380 ACP. Variation in plate 17 design would also accommodate revolver ammunition cases 23, which may include, but are not limited to, .44 Magnum, .44 Special, .357 Magnum and .38 Special. Total length and width of module 16 is dependent on case 23 type, array number (which is variable), and edge distance required for proper engagement of plate 17 in module slot 27 and function of button 26 on end of plate 17. Total dimension for the top face of the module 16 embodiment as shown for .45 caliber is 3.94 inches wide and 4.09 inches long, with length dimension being that which is aligned with the movement of the plate 17.

[0023] Referencing FIG. 3, a plate 17 with a plurality of apertures 34 matching the number and arrangement of bores 22 in the module 16 is captured in a slot in the bottom of the module 16. Module 16, plate 17, and spring 18 combination is referred herein as a module assembly 15. Plate 17 captured in slot 27 is shown in FIG. 7. Each aperture 34 is designed with beveled engaging tabs 32 which extend into the case 23 extraction groove when plate 17 is in the capture position. The apertures 34 are large enough to allow a case 23 to fall through the aperture 34 when in the release (open) position. Alternative embodiments for aperture 34 engaging tab 32 design have been shown to be functional, for example, a beveled engaging tab extending across the full width of the back face of the aperture 34. It is to be understood that the plate 17 design is not limited to the precise form shown in this embodiment.

[0024] A spring 18 provides pressure to hold the plate 17 in the capture position when at rest. The spring 18 is installed between a spring pocket 31 on the inside face of the button 26 and a corresponding spring pocket 31 on the outside face of the module. Stops at the end of the module slots 27 prevent the plate 17 from moving beyond the capture position. When cases 23 are engaged by the plate 17, force between cases 23 and plate 17 hold the plate 17 clear of the stops. Material of plate 17 is necessary to be somewhat flexible in the embodiment shown in order to slide the plate 17 into the slots 27 from the opposite end of the stops, because the button 26 extends above the height of the plate 17. If it is desired to fabricate the plate 17 from rigid material, the button 26 may be attached to the plate 17 after insertion of plate 17 in slot 27. Embodiment of the module 16, plate 17, tray 19, wedges 20, and overflow funnel 33 are preferably formed of a suitable synthetic plastics material such as ABS, PETG or polycarbonate.

[0025] A tab 30 is shown in FIGS. 1 and 2 and is also prominently seen in FIGS. 5 and 6. It is provided to aide in removal of the module assembly 15 from the tray 19, and also to provide a surface to place fingers over when operating the plate button 26 with the thumb.

[0026] FIG. 8 shows the tray 19 with supporting structure 25 on the bottom of the tray 19. A rigid screen 24 is installed over the entirety of the supporting structure 25. This horizontal screen 24 provides a platform for cases 23 on which to be supported after they have passed through the bore of the module assembly 15 and are in place and ready for module assemblies 15 to be converted to the secondary (capture) position. The screen 24 also allows liquid to pass through the tray 19. The screen is selected such that openings will not allow common case 23 cleaning media such as stainless steel pins to fall through. The tray 19 has sloped sides 28 on the sides and one end to contain cases 23 poured into the tray 19 over the module assemblies 15. The sloped sides 28 are positioned at a 45 degree angle in the preferred embodiment. The sloped sides extend from the elevation of the top of the module assemblies 15 upward approximately 1 inch. A vertical face extends from the elevation of the screen 24 to the elevation of the base of the sloped sides 28 and forms a perimeter around the module assemblies 15. The preferred embodiment contains four module assemblies 15, although it should be understood that the concept is not limited to a particular number of module assemblies 15 contained in an appropriately designed tray. One end of the tray 19 has a flat horizontal face, herein referred to as an overflow lip 29. The elevation of the overflow lip 29 is the same as the top face of the module assemblies 15. The purpose of the overflow lip 29 is to allow excess cases 23 to be swept off the top of the module assemblies 15. A removable overflow funnel 33 is affixed to the overflow lip 29 end of the tray 19, acting as an extension of the overflow lip 29 directing extra cases 23 swept off the module assemblies 15 into a container as desired.

[0027] Sides of the tray 19 are fitted with wedges 20 which slide perpendicular to the direction of the plate 17 movement. The wedges 20 are at such elevation that they may engage the button 26 on the plate 17. The wedges 20, when not engaged, are positioned back-to-back and most of the wedge 20 is outside of the tray 19 interior perimeter. When engaged, the wedges 20 are slid away from each other thereby extending them into the wedge pockets in the tray 19 interior so that the inclined plane of the wedge 20 forces the button 26 in a perpendicular direction, causing the attached plate 17 to move from the capture position to the release (open) position. After cases 23 occupy the bores 22 in the module assemblies 15, the wedges 20 may be withdrawn by moving them toward each other, at which point the module assemblies 15 will convert from the release (open) position to the capture position.

[0028] Typical workflow function of the complete primary embodiment is as follows. Wedges 20 are oriented in the back-to-back position in the tray 19. Four module assemblies 15 are inserted into the tray 19, with buttons 26 oriented within the wedge 20 pockets on each side. Wedges 20 are extended into the pockets thereby engaging the buttons 26 and converting the module assemblies 15 to release (open) position. A number of cases 23 are poured over the top of the module assemblies 15. The user gently shakes the tray 19 back and forth in a random pattern as necessary to cause the cases 23 to fall into the funnels 21 and thus occupy the bores 22. At this point any extra cases 23 are swept off the overflow lip 29 end, through the overflow funnel 33 if desired. Although it is rare, if by chance any cases 23 have not oriented correctly in the bores 22, they are picked out by hand and re-oriented. Wedges 20 are then pushed toward each other; this causes the module assemblies 15 to convert to capture position thus engaging the extractor groove of the cases 23 with the engaging tabs 32 in the plate 17 thereby holding the cases 23. The module assemblies 15 may now be picked up out of the tray 19 by the tab 15 and moved to a horizontal surface, where the user depresses and holds button 26 thereby converting the module assembly 15 to release (open) position, at which time the module assembly 15 may be lifted off the released cases 23. The released cases 23 are now ready to be coated with spray lube, inspected, and processed in any number of ways. After the cases 23 have been released, if the user wishes to transport them again as a group, the button 26 may be depressed and held and the module assembly 15 lowered over the cases 23 whereby the button 26 may be released again, capturing the cases 23 for transport.
