Abstract
In a breech-loading gun loaded by first ramming a projectile into the gun rrel to a firing position therein and then inserting a separate propelling charge, unlimited fall-back of the projectile from the firing position is prevented by means of an annular internal groove in the barrel providing a forwardly-facing shoulder, a rearwardly-facing shoulder carried by the projectile, and resilient means for automatically moving the projectile shoulder outwardly into abutting relation with the barrel shoulder on rearward movement of the projectile from its firing position. In one embodiment, the projectile shoulder is the rear end of a resilient strip extending rearwardly and outwardly from the projectile. In another embodiment, the projectile shoulder is the rear side of a radially-movable spring-biased detent on the projectile.
Claims9
In a breech-loading gun that is loaded by first ramming a projectile into the gun barrel to a firing position therein and then inserting a separate propelling charge behind the projectile, means for preventing unlimited fall-back of said projectile from said firing position, comprising:
- at least one fixed forwardly-facing internal locking shoulder on said barrel;
- at least one movable rearwardly-facing external locking shoulder on said projectile;
- said projectile shoulder being located forwardly of said barrel shoulder when said projectile is in said firing position;
- and
- resilient means for moving said projectile shoulder into abutting relation with said barrel shoulder in the event of rearward movement of said projectile from said firing position.
