Abstract: A single shot falling breech block action that includes an upper receiver assembly, a lower receiver assembly, breech block assembly, a trigger assembly, a stationary rack, a movable rack, a pinion, an action plate, and pinion rotating apparatus. The pinion rotating apparatus rotates the pinion, so that when the pinion rotating apparatus is rotated clockwise the pinion is rotated clockwise and walks rearwardly along the horizontal stationary rack while the action plate slides rearwardly and begins to cock the single shot falling breech block action and the movable rack slides rearwardly and causes the breech block assembly to slide downwardly to load a cartridge and when the pinion rotating means is rotated counterclockwise the pinion is rotated counterclockwise and walks forwardly along the horizontal stationary rack while the action plate slides forwardly and the movable rack slides forwardly and causes the breech block assembly to slide upwardly and fully cocking the single shot falling breech block action.

First Claim:
Show all 73 claims
The invention claimed is:     1. A single shot falling breech block action, comprising:
  • a) an upper receiver assembly; said upper receiver assembly having a generally rectangular-parallelepiped-shaped body with a vertical front and a vertical rear being disposed behind said vertical front of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly; said generally rectangular-parallelepiped-shaped body of said upper receiver assembly further having a horizontal top extending from said vertical front of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly to said vertical rear of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly; said generally rectangular-parallelepiped-shaped body of said upper receiver assembly further having a horizontal bottom being disposed below said horizontal top of said assembly generally rectangular-parallelepiped-shaped body of said upper receiver assembly and extending from said vertical front of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly to said vertical rear of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly; said generally rectangular-parallelepiped-shaped body of said upper receiver assembly further having a pair of opposing and vertical sides; each side of said pair of opposing and vertical sides of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly extending from a side of said vertical front of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly to a respective side of said vertical rear of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly and from a side of said horizontal top of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly to a respective side of said horizontal bottom of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly; said generally rectangular-parallelepiped-shaped body of said upper receiver assembly further having an imaginary intermediate vertical plane being disposed at a substantial midpoint between said vertical front of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly and said vertical rear of said generally rectangular-parallelepiped-shaped body of said upper receiver assembly;
  • b) a lower receiver assembly being replaceably attached to said upper receiver assembly;
  • c) a breech block assembly being replaceably and vertically slidably mounted in said lower receiver assembly and said upper receiver assembly;
  • d) a trigger assembly being replaceably mounted in said breech block assembly;
  • e) a stationary rack being replaceably and fixedly attached in said lower receiver assembly;
  • f) a movable rack being replaceably and forwardly and rearwardly slidably mounted in said lower receiver assembly and being engagable with said breech block assembly;
  • g) a pinion being clockwise and counterclockwise rotatively, and forwardly and rearwardly movably, positioned in said lower receiver and being rotatively engaged with said stationary rack and said movable rack;
  • h) an action plate being forwardly and rearwardly slidably mounted in said lower receiver assembly and being rotatively attached to said pinion, so that said pinion can rotate relative thereto; said action plate being abutable against said breech block assembly; and
  • i) pinion rotating means for rotating said pinion, so that when said pinion rotating means is rotated clockwise said pinion is rotated clockwise and walks rearwardly along said horizontal stationary rack while said action plate slides rearwardly and begins to cock said single shot falling breech block action and said movable rack slides rearwardly and causes said breech block assembly to slide downwardly to load a cartridge and when said pinion rotating means is rotated counterclockwise said pinion is rotated counterclockwise and walks forwardly along said horizontal stationary rack while said action plate slides forwardly and said movable rack slides forwardly and causes said breech block assembly to slide upwardly and fully cocking said single shot falling breech block action.
