Latest Patents

Zappa holds a patent for an "Automatic percussion primer feed mechanism." This invention is designed to automatically feed unfired primers to, and extract fired primers from, an artillery piece. The mechanism features a magazine with a rotatable cylindrical drum that carries multiple primer cartridges. This drum is detachably mounted adjacent to the breach block of the artillery piece. A user-actuable release handle controls the movement of a reciprocably mounted camplate. The camplate's movement indexes the rotatable drum to align a fresh primer cartridge with the firing chamber, while also driving a bolt to insert the unfired primer cartridge. Conversely, the camplate's opposite movement extracts the fired primer cartridge back into the magazine drum.
