Abstract

Projectile stacking systems in which individual projectiles are clipped together to form a stack. The projectiles may be joined individually by a user before loading in a barrel, or during a loading process assisted by features on the breech of the barrel. The tail of each projectile includes a set of clips which engage the nose of a trailing projectile in the stack. Projectiles may be withdrawn from barrel and undipped as required by the user.

Claims

exact text as granted — not AI-modified
1 . A clip for a projectile for a stacked projectile weapon, including:
 a first portion for engagement with the projectile,   a second portion connected to the first portion for engagement with a trailing projectile to form a stack, and   a third portion which activates the second portion during a breech loading process to cause the engagement with a trailing projectile.   
     
     
         2 . A clip according to  claim 1  wherein the first portion engages a tail part and/or a payload of the projectile. 
     
     
         3 . A clip according to  claim 2  wherein the first portion includes a longitudinal strip or a ring. 
     
     
         4 . A clip according to  claim 1  wherein the second portion engages a nose part and/or a payload of a trailing projectile or a closure for the breech. 
     
     
         5 . A clip according to  claim 4  wherein the second portion is a protrusion from the third portion, including a pin or a flange. 
     
     
         6 . A clip according to  claim 1  wherein the third portion includes a surface which is deflected or displaced by the breech of the weapon during the loading process. 
     
     
         7 . A clip according to  claim 6  wherein the third portion is a longitudinal strip or a ring. 
     
     
         8 . A clip according to  claim 1  wherein the loading process includes formation of the stack by insertion of individual projectiles into a breech portion of the weapon. 
     
     
         9 . A clip according to  claim 1  wherein the third portion is actuated by passage through the breech on insertion of the trailing projectile. 
     
     
         10 . A clip according to  claim 1  wherein the second portion engages a groove on the nose part of the trailing projectile. 
     
     
         11 . A clip according to  claim 1  having a normally open condition which is closed on engagement with the trailing projectile. 
     
     
         12 . A clip according to  claim 11  which remains closed after firing of the projectile but reopens if the projectile is unloaded. 
     
     
         13 . A clip according to  claim 1  wherein the third portion also activates the second portion during a manual stacking process outside the breech of the weapon. 
     
     
         14 . A projectile or a tail part for a projectile including a clip according to  claim 1 . 
     
     
         15 . A method of loading a weapon with projectiles to form a stack, including:
 inserting a leading projectile into a breech portion of the weapon,   inserting a separate trailing projectile into the breech portion behind the leading projectile, and   engaging the leading projectile with the trailing projectile to form the stack.   
     
     
         16 . A method according to  claim 15  wherein the projectiles are inserted longitudinally through a common aperture and the trailing projectile urges the leading projectile further into the breech portion. 
     
     
         17 . A method according to  claim 15  wherein a normally open mechanism on the tail part of the leading projectile is closed to engage the nose of the trailing projectile as the leading projectile is pushed further into the breech portion by the trailing projectile. 
     
     
         18 . A method according to  claim 15  further including inserting a closure into the breech portion after the trailing projectile and forming an engagement between a tail part of the trailing projectile and the closure. 
     
     
         19 . A method according to  claim 15  wherein the engagement is formed between one or more clips in the tail part of the leading projectile and a lateral groove in the nose part of the trailing projectile. 
     
     
         20 . A method according to  claim 15  wherein the engagement between the projectiles is disengaged by firing the leading projectile or by withdrawing the trailing projectile from the breech portion. 
     
     
         21 . A stacked projectile weapon, including:
 a barrel with a breech portion which receives a series of separate projectiles to form a stack, and   a firing system on the barrel which is aligned with the stack and activates respective primers for the projectiles,   wherein the breech portion includes an entry portion which actuates an engagement mechanism between consecutive projectiles.   
     
     
         22 . A weapon according to  claim 21  wherein the entry portion includes an aperture having an edge which closes a tail part of each leading projectile into engagement with a nose part of a corresponding trailing projectile as the stack is formed. 
     
     
         23 . A weapon according to  claim 21  wherein the barrel is a receiver which forms part of a relatively longer barrel in the weapon. 
     
     
         24 . A weapon according to  claim 21  further including a breech closure which engages the last trailing projectile in the stack.
