  • 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: 11561076
    Abstract: Described is an ammunition production loading machine. The machine will load two cartridges at once and is referred to as a ‘two-out” machine. The machine will be of a mechanical nature reducing the potential loss of production that occurs with pneumatic systems. Any pneumatic systems on the machine will operate only in failure instances, i.e. in the case of a powder failure the pneumatic system will obstruct the projectile feed mechanism. The machine consists of seven (7) major components, which operate in unison. The machine is intended to run a single caliber so changeover adjustments and time required to change calibers are eliminated. The machine is capable of precisely loading a complete cartridge at a rate of 240 parts per minute in a completely automated manner. The key features of this novel machine are the full automation from station to station and a cartridge retaining bullet crimp case bushing in a rotating main disk, which rotates cases from station to station.
