The present invention relates generally to a firearm gas redirection assembly. More so, the present invention relates to a firearm barrel that directionally directs the discharged gases generated by a projectile from a firearm barrel towards a jet nozzle edge, using the energy from the discharged powder gases to force the bolt frame rearwardly; whereby a bolt frame comprises a bolt frame lip surface and a bolt that is operable to slide rearwardly immediately upon discharge of the firearm, and the bolt is further operable to recoil and slide forward after discharge of the firearm; whereby a barrel is defined by an elongated body, an inner barrel sidewall, an outer barrel sidewall, a rear end, and a forward end terminating at a muzzle; whereby the forward end of the barrel forms at least one gas vent; the barrel is fixed motionless on the frame of the weapon; whereby a jet nozzle concentrically couples around the barrel and integrates with the bolt frame, and the jet nozzle is defined by an inner jet sidewall, an outer jet sidewall, and a jet nozzle edge; whereby the inner jet sidewall and the outer barrel sidewall form a gas space that is in communication with the bolt frame; whereby discharge of the firearm forces a high velocity gas through from the at least one gas vent against the jet nozzle edge through the gas space, so as to displace the bolt frame rearwardly.
The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.
Typically, Semi-automatic pistols generally include a frame having a grip portion for grasping by the user, barrel defining a chamber for holding a cartridge, trigger-actuated firing mechanism for cocking and releasing a striker or hammer to detonate the cartridge, and an axially reciprocating bolt. The bolt defines a breach block for forming an openable and closeable breech with the rear of the chamber as well known to those skilled in the art.
It is known in the art that a bolt assembly is required in a firearm to manage recoil in order to effectively absorb the kinetic energy generated by gases form the discharged projectile. The bolt is a mechanical part of a firearm that blocks the rear of the chamber while the propellant burns, but moves out of the way to allow another cartridge or shell to be inserted in the chamber. This helps manage the recoil of the high velocity gases against the bolt.
Other proposals have involved removing gases and the energy needed to perform a cycle of automation and reloading that are generated in a barrel discharged projectiles. The problem with these is that they require a massive and bulky gas chamber for removing part of the powder gases, and also a gas piston. Even though the above cited gas redirecting assemblies meet some of the needs of the market, a firearm gas redirection assembly that directed directs the discharged gases generated by a projectile from a firearm barrel towards a bolt frame, using the energy from the discharged powder gases to force the bolt frame backward is still desired.
Illustrative embodiments of the disclosure are generally directed to a firearm gas redirection assembly. The firearm gas redirection assembly serves to directional direct discharged gases generated by a projectile from a firearm barrel against a jet nozzle edge, and then use the energy from the discharged powder gases to force the bolt frame backward. The bolt frame is operable to slide backward immediately upon discharge of the firearm, and the bolt frame is further operable to recoil by sliding forward after discharge of the firearm.
The barrel is defined by an elongated body, an inner barrel sidewall, an outer barrel sidewall, a rear end, and a forward end terminating at a muzzle. The forward end of the barrel forms at least one gas vent. The barrel is fixed motionless on the frame of the weapon. A jet nozzle concentrically couples around the barrel. Jet nozzle also integrates with bolt frame. The jet nozzle is defined by an inner jet sidewall, an outer jet sidewall barrel, and a jet nozzle edge. The inner jet sidewall and the outer barrel sidewall form a gas space that is in communication and integrated with the bolt frame, and axially in communication with the bolt. In this manner, discharge of the firearm forces a high velocity gas through from the at least one gas vent in the barrel, against the jet nozzle edge, and to the bolt frame for displacement, through the gas space. As a result, the bolt frame and bolt are moved rearwardly in relation to the barrel.
In one aspect, a firearm barrel gas redirection assembly, comprises:
In another aspect, the firearm is a pistol.
In another aspect, the at least one gas vent comprises multiple gas vents forming a circle around the outer barrel sidewall.
In another aspect, the barrel comprises a barrel logging lug.
In another aspect, the bolt frame is axially aligned with the barrel.
In another aspect, the cylindrical jet nozzle couples outside the muzzle.
In another aspect, the bolt frame comprises a striker concentric to the bolt.
In another aspect, the barrel has an arbitrary cross-sectional shape that is different from round or barrel-like.
In another aspect, the jet nozzle integrated or communicating with the bolt frame has a cross-sectional shape that is different from round or barrel shaped.
In another aspect, the bolt frame is not equal in length and is not aligned with the muzzle of the trunk in the normal state.
In another aspect, the muzzle barrel may have o-rings, as well as protuberances of arbitrary shape, to increase pressure in the gas space.
In another aspect, the jet nozzle is integrated into the bolt frame.
In another aspect, the jet nozzle is a separate piece communicating with the bolt frame.
In another aspect, the bolt does not have a bolt frame and it works independently.
In another aspect, the jet nozzle acts directly on the bolt.
In another aspect, the bolt works with the bolt frame and the bolt frame acts on the bolt, allowing the bolt to open and close, and also moving the bolt back and forth to reload the weapon.
In another aspect, the bolt frame comprises a rotary cam.
In another aspect, the assembly is operational with a firearm.
In another aspect, the firearm further comprises a frame.
In another aspect, the frame comprises a metal housing and a handle.
One objective of the present invention is to redirect the energy from gases generated by a discharged projectile to displace a bolt frame and bolt rearwardly.
Another objective is to provide a firearm does not require a massive and bulky gas chamber for removing part of the powder gases.
Another objective is to provide a firearm that does not require a gas piston.
Yet another objective is to form gas vents in the front end of the barrel.
Yet another objective is to combine the jet nozzle with the side openings for the removal of powder gases from the barrel.
Yet another objective is to provide an inexpensive firearm accessory that creates more efficient bolt frame and bolt action.

A firearm gas redirection assembly 100 is referenced in

Looking at
As shown in
Most significantly however, firearm 102 comprises a barrel 124, which is a metal tube that the projectile travels through. The forward end 134 of barrel 124 is fitted with a cylindrical jet nozzle 142 that works in conjunction with the barrel 124 to redirect discharged gases normal to a bolt frame. In this manner, the bolt frame 114 and bolt 116 is displaced rearwardly, away from the barrel 124 to absorb the force and also to enable loading of a new projectile.
Turning now to
Bolt frame 114 comprises a bolt 116 that is operable to slide rearwardly immediately upon discharge of the firearm 102, so as to enable a new projectile, i.e. bullet, can be loaded into the chamber. Bolt 116 is further operable to recoil by sliding forward after discharge of the firearm to load the newly loaded projectile. Bolt 116 is axially aligned with the barrel 124, so that when the charge in the cartridge ignites, the gas presses on the cartridge sleeve and presses the bolt 116 through the sleeve. Bolt 116 is held fixed by the bolt locking lug 122 during firing, forcing all the expanding gas 158 forward, and is manually withdrawn to chamber another round.
Looking at
In one embodiment, forward end 134 of barrel 124 forms at least one gas vent 140a-f. Gas vent 140a-f provides an escape for the discharged gases 158 that are generated by a discharged projectile, and normally exit from muzzle 138 of barrel 124. Gas vent 140a-f extends into barrel sidewalls 128, 130. In some embodiments, multiple gas vents 140a-f form in barrel 124 in equal number, and in alignment on opposing sides of barrel 124. In another embodiment, multiple gas vents 140a-f are arranged around the periphery of the forward end of the barrel. In some embodiments, barrel 124 may also utilize a barrel locking lug 136 to attach barrel 124 to a firearm action. This is possible as the barrel locking lugs 136 engage the bolt locking lug 122, providing closure of the bore of the barrel 124 upon firing.
As the close up view of
In some embodiments, jet nozzle 142 is defined by an inner jet sidewall 144, an outer jet sidewall 146, and a jet nozzle edge 160. The inner jet sidewall 144 and the outer barrel sidewall 130 form a gas space 150 that is in communication with bolt frame 114, and axially in communication with the bolt 116. In this manner, discharge of the firearm forces a high velocity gas through the at least one gas vent 140a-f and into barrel 124.
Looking now at the forward and rearward view of
At the beginning of the cycle, the powder gases act on the bolt frame 114 with a large amount of force necessary to turn and open the bolt 116. This causes the jet nozzle 142 to be forcibly displaced rearward, until jet nozzle 142 ceases to cover with the gas vent 140a-f. This leaves a free space for the gas powder to expand unchecked by jet nozzle 142. However in some embodiments, bolt frame 114 continues to move back under the action of the residual pressure of the powder gases in barrel 124 for the automation cycle. Together with a buffer, this provides soft operation of the automation.
Furthermore, since bolt frame 114 does not absorb strong shock loads, bolt frame 114 can be fabricated of steel or titanium. In the case of making bolt frame 114 from titanium, the impulse of recoil of the firearm during discharge is significantly less, since the moving parts during the discharge (bolt 116 and bolt frame 114) is easier in the aggregate. Thus, assembly 100 is operable in two types of shock-trigger mechanism: a shock-trigger mechanisms; and a striker or trigger type.
These and other advantages of the invention will be further understood and appreciated by those skilled in the art by reference to the following written specification, claims and appended drawings.
Because many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
