Rotary Shell Feed Patents (Class 86/27)
  • Patent number: 11768064
    Abstract: The herein described Table Top Priming Machine for Small Caliber Ammunition provides a simple, safe, and more precise means to produce reliable ammunition than other priming machines in the prior art. The Table Top Priming Machine uses a unique rotary disk assembly to hold cases as the machine installs primers into the cases. Gravity assists with securing cases in the disk assembly and promotes ejection of the finished cases. The compact construction of the machine makes the machine accessible for individuals or manufactures with limited space to create consistent ammunition at high speeds with limited space. Furthermore, the machine's design allows for any end user to assemble and maintain the machine with general hand tools, which obviates the need for specialized maintenance from the manufacturer.

  • Patent number: 11698246
    Abstract: As described above, this new primer feed system is both accurate and consistent. The primer feed station begins by loading primers from the vendor packaging into the vibratory feed bowl via the primer chute. The bowl has an adjustable height polycarbonate guard that is inside the main safety polycarbonate doors and exits above the machine. The bowl then orients the primers open side up and discharges them into the primer track. Crimping can be done with 3 or 5 pins or a complete radial crimp. Previous versions of the crimp station on these crimping machines involved a pin mounted to the upper ram and a lower pin actuated by the lower ram. It was difficult to time and adjust properly for a consistent crimp. This new approach to crimping has proved much more reliable, accurate and easier to adjust. It still utilizes an upper pin mounted to the upper moving ram assembly but the lower pin is fixed.

  • Patent number: 6772668
    Abstract: Ammunition reloading apparatus includes a shell case support for holding a shell case, a container spaced above the support for holding shell loading material to be placed in a shell case during reloading, and an elongate charge bar underlying the container having a charge opening therein. The bar is mounted for movement between a first position in which the opening underlies the container to receive a charge of material and a second position where the material may be released to an underlying shell case. Control mechanism is operable to sense the presence or absence of the shell case on the support when the charge bar is in its second position. The control mechanism prohibits release of material from the charge opening when a shell case is absent and permits release of material to be dispensed to the shell case when a shell case is present.

  • Patent number: 5313869
    Abstract: A shell plate for being indexed in angular steps is on a carrier which is, in turn, mounted to the upper end of the reloader ram. Indexer rod engageable elements such as cylindrical equiangularly spaced apart pins project downwardly from the bottom of the shell plate. An indexer rod is carried in the shell plate carrier. When the ram is driven to nearly its lowermost position, the manual operating lever is near the end of its swing at which time it abuts the indexer rod for the latter to engage one of the pins to rotate the shell plate. The indexer rod is retracted and reset by having it slide down a guide track from the uppermost position of the ram and the guide track is angulated in part to be engaged by the rod and retracted. The reloader is distinguished by indexing the shell plate only when the ram is within a few millimeters of its lowermost limit.

  • Patent number: 5040449
    Abstract: In a shotgun shell reloader, a manually operated lever drives a carriage reciprocally on a central post for shotgun shells mounted to the carriage to engage with reloading tools arranged on a support which mounts to the upper end of the post. A circular shot plate mounts to the carriage and has a central bore for surrounding the post. An indexer member mounts in the bore of the shell plate and surrounds the post. The indexer has a helical groove in its bore which rides onto a pin extending radially from the post when the carriage is beginning to be raised so that the indexer, which is engaged with the shell plate at that time, turns the shell plate through one angular increment so that a shell on the plate will be presented to tools on the tools support successively to perform the reloading process. A powder bar and a shot bar are mounted to the top of the tool support for moving under a hopper which has chambers for powder and shot.

  • Patent number: 4852451
    Abstract: Disclosed is a device for sensing the powder level within a cartridge shell during the reloading process comprising a housing having a ramp in its interior, a sleeve slidably inserted within the housing having a radial hole initially positioned below the ramp in which resides a ball, and a plunger inserted within the sleeve having a groove for receipt of the ball. A probe is mounted on the lower end of the plunger which contacts the powder deposited in the cartridge shell, wherein the probe lifts the plunger so that the groove in the plunger may receive the ball upon the presence of a proper amount of powder so the sleeve can slide upward into the housing allowing the cartridge to enter the housing. Preferably, the powder level sensing device is adapted to be mounted onto existing reloading press frames, particularly the progressive reloading press frame. Also disclosed is a method for adjusting the powder level sensing device to accommodate various cartridge shells and desired powder levels.

  • Patent number: 4841831
    Abstract: A reloader for reloading cartridges. A reciprocating plunger carries a turret that rotates around the axis of the plunger. The turret carries a plurality of cartridges for reloading, the cartridges being symmetrically spaced around the turret axis and adapted to be indexed around the axis in a step-by-step sequence. An overhead die holder contains a plurality of dies spaced in a symmetrical pattern similar to that of the cartridges but in fixed positions. A center opening in the die holder houses a rotatable bushing. The rotation of the bushing is controlled in part by a one-way clutch. An indexing shaft affixed to the turret extends from the turret axis through the bushing. The shaft has a multi-sided cross section and is slidably fitted to the bushing in a manner that prevents relative rotation. The configured cross section has an axial twist and when forced through the bushing by the reciprocating plunger, causes turning of one or the other of the shaft and turret or the bushing.

  • Patent number: 4526084
    Abstract: To enable a shell to be automatically primed during operation of a loader, the primers are mounted within a chute to fall by gravity to an opening where a lever is pivoted by a cam as the shell carriage of the loader moves in a vertical direction within the frame of the loader. The motion of the lever moves one of the primers from the chute into position underneath the shell carriage for insertion into the shell casing as the carriage moves downward against the base of the loader frame. The lever arm is spring-biased into position underneath the rim of the holder and contacts a cam mounted to move up and down with the carriage upon the actuating of the loader handle by an operator. The shell is deprived during the upward movement of the carriage and the downward movement.

  • Patent number: 4515063
    Abstract: Cartridge reloading presses wherein either a turret carrying multiple dies or a turret carrying multiple cartridges is caused to index rotationally relative to the axis of a vertically reciprocable ram. The indexing mechanism includes a ratchet element having a circular array of downwardly pointed teeth surrounding a vertical hole. This element is fixed to the ram. A hexagon rod having a nominal 120 degree twist near its lower end fits through said hole with clearance. A plastic ratchet element having upwardly pointed complementary teeth surrounding a hexagon hole fits snugly on the hexagon rod. When the ram moves upwardly the two ratchet elements are disengaged so the rod does not turn. During the ram downstroke, the ratchet elements engage while the plastic element is still on the untwisted part of the rod. Near the end of the downstroke, the engaged and locked plastic element runs onto the twist, causing the rod to rotate to thereby rotate a turret engaged therewith.
