U.S. Pat. No. 4,604,942 issued on Aug. 12, 1986, to Paolo Benelli and is titled Bolt Assembly with a Rotating Locking Bolt Head and a Floating Bolt Element for Automatic Firearms. This patent discloses a bolt assembly for an automatic firearm which operates using kinetic recoil energy that includes a floating bolt element, a rotatable locking bolt head and a return spring interposed between them, all in communication with the barrel. The bolt head is formed with a cylindrical portion having two crescent shaped projections located at diametrically opposite points along the circumference of the cylindrical portion. The barrel is also formed with a pair of grooves, each groove associated with a recess such that the projections may enter and exit the grooves through the recesses. Upon firing, the return spring is compressed which momentarily keeps the bolt head in a locked position which causes a delay to allow for the dissipation of pressures in the barrel. While this patent is for a rotating bolt head the reloading is from inertia as opposed to utilizing the expanding gunpowder gas.
U.S. Patent Publication Number 20180172375 was published on Jun. 21, 2018, to Herbert Stangle et al., and is titled Firearm of the Rotating Bolt Type. This publication discloses a firearm of the rotating bolt type includes a housing part made of plastic or metal, a metal bolt carrier guide, a bolt carrier that is guided by the bolt carrier guide and that has a bolt head rotatably mounted that is held by the housing part, a metal barrel nut in which a barrel can be fixed and in which the bolt head can be locked. The bolt carrier guide is directly connected with the barrel nut so that it is rigid with respect to movement, at least in the longitudinal direction of the firearm. While this publication is for a rotating bolt, the bolt must travel rearward in the firearm for ejecting the shell.
European Number EP3179193 was granted on Jun. 27, 2018, to Friedrich Dechant and is titled Pistol with rotating barrel. This patent discloses a pistol with a frame, a closure movable thereon and a rotary run located in the closure. The rotation is rotated by cams and grooves with respect to the closure between a locked position and an open position and moved axially. In order to avoid the usual wear in such weapons wear is provided that the closure has an obliquely to the axis of the soul extending abutment surface, and the barrel a corresponding contact surface. Thus, when locking by the surface contact between these surfaces, the beginning of the relative rotational movement is initiated. Thus, it is possible to reduce the wear by order of magnitude by precisely guided and directed interaction. While this patent is for a rotating barrel, the closure uses an oblique closure as opposed to using a round closure with a rotational spring.
What is needed is a firearm with a rotating, or otherwise laterally/vertically separating chamber where components can move in any direction to separate, and thus create a chamber around newly loaded firearm casing/round that has a reduced weight and materials needed to actuate all of the components, so more energy is available to transfer rotating energy, instead of the typical lateral slide movement. It should also remove the large slide component and replace it with a two-part chamber locking assembly to negate the requirement for a round to move laterally after moving vertically. The proposed firearm with a two-part chamber locking assembly disclosed in this document provides the solution.
This invention relates to improvements in firearms. More particularly, the present firearm with a multi-part chamber locking assembly where the breach rotates or otherwise separates into multiple parts to eject and reload a new cartridge. The firearm can be a handgun, rifle or general artillery system.
Most firearms use the recoil of the expanding gunpowder in a cartridge to propel a projectile, eject the casing and rechamber a new round. This is most commonly performed by the bolt moving backwards to then strip a round. Some firearms use a rotating bolt that allows for the bolt to rotate for discharging the spent casing and reloading a new cartridge. A number of patents and or publications have been made to address these issues. Exemplary examples of patents and or publication that try to address this/these problem(s) are identified and discussed herein.
It is an object of the firearm with multi-part chamber locking assembly to allow the casing ejecting and the reloading sequence to be temporarily slowed down to capture the optimum amount of expanding gun powder prior to the round exiting the barrel, this is typically done through a lug or pivoting hinge point, which pivots off of the lower frame.
It is an object of the firearm with multi-part chamber locking assembly to remove the large slide component(s) and replace it with a two-part cylindrical 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.
It is another object of the firearm with multi-part chamber locking assembly to reduce the weight and materials needed to actuate all components of the ejecting and reloading so more energy is available to transfer rotating or multi-directional ejecting energy, instead of the common rearward/forward loading movement of the casing ejecting process.
It is another object of the firearm with multi-part chamber locking assembly in the hammer or striker to have a direct impingement or a firing pin actuated action on a primer to ignite the propellant. This striking action can actuate mechanically off of the rotating cylinder, electrically, magnetically, hydraulically, though ferro fluid or chemically.
It is still another object of the firearm with multi-part chamber locking assembly for the primary actuating to occur through either direct impingement and piston gas that assist to first push the cylindrical cap, rotary cylinder, striker/hammer— lock/back and other machine required actuations.

The translating barrel assembly 50 chambers a cartridge with a projectile (not shown) in chamber 21 of a breach 52. One side of chamber 21 translates by moving one side of the breach on linear slide(s) 53. Translating barrel assembly 50 is biased by a spring or springs that hold the door in a closed configuration. A trigger mechanism 70 is retained in the rear site block 31. The trigger mechanism is shown in
The hammer mechanism 70 or striker is shown in this embodiment with a direct impingement or piston actuated action on the primer of a cartridge, however it's anticipated that the mechanism can actuate mechanically off of the rotating chamber, electrically, hydraulically, though ferro fluid or chemically. The actuation can utilize aspects from a common revolver, which includes single and double actions that move the hammer/strike, primary cylinder, cylinder cap, and ejector system.
The translating barrel assembly 50 has a breach casing retainer 56 with a complementary recess in the upper frame 41 for the other (far) corner of a casing. In this embodiment the shell in chamber 25 would be rectangular or square. The translating barrel assembly 50 has a casing ejector pocket 57 where a breach casing retainer 56 operates. The breach casing retainer 56 is shown and described in more detail in other figures herein. The shell is fired when the firing pin 72 extends through the firing pin hole 73 and into the shell or a primer in the shell. Expanding gunpowder passes through the front tube in barrel 81 to unlock the slide door lock 54. A second side gas tube 80 pushes open the translating barrel assembly 50.
The breach casing retainer 56 rotates on a pivot axle 29 on the translating chamber assembly 50 as the translating barrel assembly 50 translates out of the upper frame 41 as the linear slide(s) 53 pass in the linear slide passage(s) 59. In the closed position the slide door lock 54 holds the translating barrel assembly 50 closed. When the shell is fired, the expanding gunpowder passes through the front tube in barrel 81 to unlock the slide door lock 54. The slide door lock 54 pivots on pivot axle 47. A second side gas tube 80 pushes open the translating barrel assembly 50.
On one side of the shell is a notch 28 that runs down the entire side. This notch 28 guides the casing on a casing guide 27 in the back of the upper frame 41. The casing recess 48 in the translating barrel assembly 50 pushes the casing into the casing guide 27. The notch 28 and casing guide 27 holds the casing is position on the firing pin hole 73. The far end of the upper frame 41 is the barrel opening 42.

In
The rotary chamber assembly 32 chambers a cartridge with a projectile (not shown) in a chamber 21 of a breach. Chamber 21 is rotate in rotary barrel assembly 32 that is biased by a front spring 39 and a rear spring 61. The front spring 39 and the rear spring 61 hold the cartridge in a desired position for firing and also holds the ejection door closed. A trigger mechanism 70 is retained in the rear site block 31. The trigger mechanism is shown in
The hammer mechanism 70 or striker is shown in this embodiment with a direct impingement or piston actuated action on the primer of a cartridge, however it's anticipated that the mechanism can actuate mechanically off of the rotating chamber, electrically, hydraulically, though ferro fluid or chemically. The actuation can utilize aspects from a common revolver, which includes single and double actions that move the hammer/strike, primary cylinder, cylinder cap, and ejector systems.
A rear spring (not visible in this figure) is located in rear rotation frame 36. The front spring 39 (and a rear spring) in this embodiment is essentially a compression spring set in between the rotating breach and the rotation frames in an arc sector recess. While a compression spring is shown and described, other springs or biasing mechanisms are contemplated, including but not limited to, a torsion spring, extension spring and air-filled piston. Breach or firing chamber 21 has a circular breach frame 38 with an ejection door 58 where a spent cartridge is ejected. Although a typical circular breach frame 38 is indicated, it's anticipated that caseless ammo will be utilized, as well as two-part system Ammo wherein the propellent and round are contained separately.
When the cartridge is fired the projectile (not shown) will pass through an opening 22 in the front frame 34 and enter barrel 20 (previously shown and described). Although the current system indicates a typical ejector featured on the rotating barrel assembly 32 cylinder, other mechanical and non-mechanical based ejection systems are anticipated, including a gateway hole drilled in the rotating barrel assembly 32 cylinder system that is timed to directly impinge or mechanically actuate the removal of the contained round as needed.
Expanding gunpowder from the cartridge passes into ports 83, side port 85 (or more ports) into the manifold tube 82 and or front gas tube 88. The pressurized expanding gunpowder pushes against blade(s) connected to the circular breach frame 38 to overcome the spring force of the front spring 39 (and rear spring) to rotate the circular breach frame 38. The manifold 82 can also be connected to an upper port 84 and or rear port 86 for operation of ejecting the spent shell. The preferred embodiment discloses one primary rotating barrel assembly 32 and one primary cylinder cap, but it is contemplated that multiple components can be used.

The manifold 82 can also be connected to an upper port 84 and or rear port 86 and or side port(s) 87 for operation of ejecting the spent shell.
The current embodiment represents a direct impingement based vertically lifting cylinder cap, while other forms of actuation are anticipated including mechanically, rotary, cam, rotating, pneumatic, hydraulically, chemical, and liquid metal based.
Thus, specific embodiments of a firearm with a two-part cylindrical locking assembly have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
