Abstract

Improvements in a firearm with a multi-part chamber locking assembly is disclosed to allow the casing ejection and reloading sequence to be temporarily slowed down to capture the optimum amount of ignited gun powders expanding gas, prior to the round exiting the barrel. Large slide component(s) of a firearm are replaced with a multi-part chamber locking assembly. This negates the requirement for a round to move laterally after moving vertically. The round only moves vertically thus mitigating the requirement for any forward motion. The multi-part chamber reduces the weight and materials needed to actuate all components of the ejecting and reloading process, so more energy is available to transfer movement of casing ejecting. The round is fired with a hammer or striker through impingement or a firing pin actuated action on a primer to ignite the propellant.

Claims (16)

1. A firearm with at least a two-part chamber locking assembly comprising:

a first part having a fixed frame that supports a second part having a rotary chamber;

said rotary chamber is biased at a first position within said fixed frame;

said rotary chamber being axially aligned with a hole in said fixed frame and a hole in a barrel that is configured for a projectile to pass therethrough;

launching said projectile causes said rotary chamber to rotate in a first direction of rotation and eject a temporarily retained shell out of said rotary chamber;

after said shell has been ejected a second projectile is loaded vertically into a bottom of said rotary chamber from a removable magazine, and

said rotary chamber rotates axially in a second direction of rotation, that is opposite of said first direction of rotation, around said second loaded projectile to said first position.

2. The firearm with at least a two-part chamber locking assembly according to claim 1 , wherein said biasing mechanism is at least one compression spring.

3. The firearm with a two-part chamber locking assembly according to claim 2 , wherein there said at least one compression spring is formed in an arc sector between said fixed frame and said barrel.

4. The firearm with at least a two-part chamber locking assembly according to claim 1 , further includes a manifold the directs expanding gun powder from launching said projectile around said rotating barrel to rotate said rotating barrel and/or eject said shell.

5. The firearm with at least a two-part chamber locking assembly according to claim 1 , wherein said firearm is a handgun, a rifle, or an artillery system.

6. The firearm with at least a two-part chamber locking assembly according to claim 1 , actuates mechanically off of a rotating or otherwise multi-part cylinder, electrically, pneumatically, magnetically, hydraulically, through ferrofluid, or chemically or through a manual mechanical timing using a pawl and ratchet.

7. The firearm with at least a two-part chamber locking assembly according to claim 1 , further includes ammunition that stores gun powder or propellent separate from the round loaded into the chamber.

8. The firearm with at least a two-part chamber locking assembly according to claim 4 , wherein said manifold extends to front and back ends of said chamber.

9. The firearm with at least a two-part chamber locking assembly according to claim 3 , wherein there is at least a second compression spring placed at an opposite side of said chamber.

10. The firearm with at least a two-part chamber locking assembly according to claim 1 , wherein said temporarily retained shell is ejected out a left or right side of said chamber.
