Description
FIELD OF INVENTION
[0001] The disclosure relates to devices, systems and methods for
extraction of cartridge cases from firearms chambers. More
specifically, the disclosure relates to a firearm chamber
comprising channels and associated systems and methods.
BACKGROUND OF THE INVENTION
[0002] Common failure modes associated with rotating bolt firearms
include for example, failure to extract failures and blown primer
failures. Failure to extract failures occur when a cartridge is
activated (e.g., fired) and the bullet travels through and out the
muzzle of the barrel, but the cartridge case fails to eject from
the firearm chamber. Blown primer failures occur when the primer is
struck and activated, but the powder contained in the cartridge
case is not ignited. In this way, the bullet is not fired, but the
chamber is rendered inoperative until the action of the firearm is
cycled or cleared to remove the cartridge. This disclosure provides
devices, systems, and methods that improve the reliability of
firearms by minimizing these and other failure modes, increasing
reliability of the firearm.
SUMMARY OF THE INVENTION
[0003] In various embodiments, a firearm assembly is provided. The
firearm assembly can comprise a barrel and a chamber comprising a
channel. The chamber has a first length. The chamber may comprise
an internal wall defining an internal cavity. The chamber can also
couple to the barrel. The channel can be defined in the internal
wall of the chamber. The channel may have a second length that can
be shorter than the first length. In various embodiments, the
firearm assembly may be a component of a rotating bolt firearm. In
various embodiments, the internal cavity of the firearm assembly
has a profile configured to receive a cartridge.
[0004] In various embodiments, a firearm can be configured to
activate (e.g., fire) a cartridge comprising a case and a bullet.
The firearm may comprise an upper receiver and a barrel. The barrel
may detachably couple to the upper receiver. The barrel may also
comprise a chamber portion. The chamber portion can be configured
to slidably receive the cartridge. The chamber portion can comprise
a first groove defined in a wall of the chamber portion. The first
groove may be in fluid communication with the barrel. The chamber
portion may also comprise a second grove defined in a wall of the
chamber portion. Similarly, the second groove may be in fluid
communication with the barrel. In response to the cartridge being
activated, the first groove and the second groove can be configured
to direct gas from at least one of the barrel and the chamber
portion to create a force (e.g., pressure) on the case.
[0005] In various embodiments, the case may comprise a neck, a
shoulder and a body, and the force can be applied to at least one
of the neck, the shoulder and the body. In various embodiments, the
case may comprise a body and the force can be applied to the
body.
[0006] In various embodiments, the first groove and the second
groove are defined along a diameter of the chamber portion. The
first groove may be substantially parallel to the second
groove.
[0007] In various embodiments, the force may be applied to the case
tangentially.
[0008] In various embodiments, a centerline of the barrel can be
defined along a center of a diameter of the barrel. In these
embodiments, a first component of the force may be applied to the
case in a direction substantially perpendicular to the centerline
of the barrel and a second component of the force may be applied in
a direction substantially parallel to the centerline of the
barrel.
[0009] In various embodiments, as barrel is provided. The barrel
can comprise barrel portion and a chamber portion. The chamber
portion may be coupled to the barrel portion. The chamber portion
may be configured to operatively receive a cartridge. The chamber
portion may also comprise a first channel and a second channel. The
first channel and the second may be in fluid communication with at
least one of a first volume defined by the chamber portion and a
second volume defined by a portion of the barrel portion. In
response to activating the cartridge, at least one of the first
channel and/or the second channel may be configured to conduct a
gas pressure from at least one of the first volume and the second
volume to an exterior surface of the cartridge.
[0010] In various embodiments, the chamber portion may comprise a
third channel and a fourth channel. The third channel and/or the
fourth channel may be in fluid communication with at least one of
the first volume and the second volume.
[0011] In various embodiments, the first channel, the second
channel, the third channel and the fourth channel may be spaced
equidistantly around a diameter defined by the chamber portion.
[0012] In various embodiments, the length of the first channel can
be substantially equal to the length of the second channel. The
length of the first channel may be shorter than the length of the
chamber portion.
[0013] In various embodiments, a rotating bolt firearm is provided.
The rotating bolt firearm may comprise a gas operating system, a
bolt, and a barrel. The barrel may comprise a chamber or a chamber
portion. The bolt may be rotatably moveable between a first
position and a second position. The chamber portion of the barrel
may be configured to receive the bolt. The chamber portion may
comprise a first channel. The volume defined by the barrel may be
in fluid communication with the gas operating system and a first
channel defined in the chamber portion. The pressure created by
activating a cartridge in the rotating bolt firearm can cause gas
to pressurize an outer surface of a cartridge via the first
channel, during a time period between the activation of the
cartridge and the pressure actuating the gas operating system.
[0014] In various embodiments, the first channel can be defined in
an interior surface of the chamber portion.
[0015] In various embodiments, the chamber portion may comprise a
second channel.
[0016] In various embodiments, actuating the gas operating system
can cause the bolt to rotate from the first position to the second
position. Moreover, actuating the gas operating system can cause
the cartridge to eject from the chamber portion.
[0017] In various embodiments, the gas can create a force (e.g., a
pressure) that can be exerted on the outer surface of the
cartridge.
[0018] In various embodiments, the devices, systems and methods
described herein improve the reliability and functionality of
various firearm components (e.g., extractors, barrels, chambers,
and or the like). These devices, systems and methods also reduce
operation failures. Moreover, these devices, systems and methods
maintain accuracy and functionality of rotating bolt firearms.
[0019] In various embodiments, the devices, systems and methods
described herein encourage the ejection, compression, and/or
contraction of the cartridge case in response to firing a cartridge
from a rotating bolt firearm.

DETAILED DESCRIPTION
[0026] The detailed description of exemplary embodiments herein
makes reference to the accompanying drawings, which show exemplary
embodiments by way of illustration and their best mode. While these
exemplary embodiments are described in sufficient detail to enable
those skilled in the art to practice the inventions, it should be
understood that other embodiments may be realized and that logical,
chemical and mechanical changes may be made without departing from
the spirit and scope of the inventions. Thus, the detailed
description herein is presented for purposes of illustration only
and not of limitation. For example, the steps recited in any of the
method or process descriptions may be executed in any order and are
not necessarily limited to the order presented. Furthermore, any
reference to singular includes plural embodiments, and any
reference to more than one component or step may include a singular
embodiment or step. Also, any reference to attached, fixed,
connected or the like may include permanent, removable, temporary,
partial, full and/or any other possible attachment option.
Additionally, any reference to without contact (or similar phrases)
may also include reduced contact or minimal contact.
[0027] In various embodiments, a firearm chamber comprising one or
more channels is provided. The chamber may be integrally formed in
or couple to the barrel. The chamber may also be a portion of a
larger barrel assembly (e.g., a barrel extension). The chamber can
be implemented or used with any suitable firearm including, for
example, an automatic firearm, a semi-automatic firearm, a bolt
action firearm, and or the like. The firearm may include any
suitable action including, for example, a rotating bolt action
(e.g. the action of an AR-15 style rifle), a falling block, a
rolling block, or any other suitable action. Similarly, the chamber
can be used in a rotating bolt firearm with any suitable actuation
system including for example, a gas piston system, a gas
impingement system, a manual actuation system, and/or the like.
[0028] In various embodiments and with reference to FIG. 1, a
firearm 100 can comprise a barrel 120 and a chamber 125. Chamber
125 can comprise one or more channels 126. Channel 126 may be any
suitable passage, groove, flute, gap, or other suitable channel
defined in the inner diameter of chamber 125. Chamber 125 is
configured to operatively receive a cartridge of ammunition. In
operation and in response to the firearm being fired, the cartridge
is activated causing the case to be retained in the chamber (at
least momentarily) and the bullet to travel through barrel 120.
[0029] In various embodiments. Channel 126 may also be in fluid
communication with a portion of the volume defined by chamber 125
and/or barrel 120. The volume defined by channel 126 pressurizes
with gas from an activated cartridge. The pressure can be directed
by channel 126 to an exterior surface on the case of the cartridge.
The pressure creates force on the case (e.g., the outer surface of
the case) that encourages ejection, contraction, and/or compression
of the case. When the cartridge is activated, the case expands in
response to powder ignition and the bullet being shot from the
mouth of the case. The expansion is intended to be elastic. The
elastic properties of the case allow the case to retract after
activation before the case is ejected from chamber 125. However,
cartridges can plastically deform or otherwise become jammed in the
chamber causing failure to extract failures (e.g., the case remains
in the chamber and will not extract). Failure to extract failure
may occur for various reasons, including, for example, cartridges
loaded with extra powder (e.g., "hot loads") to provide greater
ballistic performance, case fatigue, case imperfections, debris in
the chamber, and/or the like. The devices, systems and methods
described herein minimize these failures by encouraging ejection,
contraction, and/or compression of the case.
[0030] In various embodiments, barrel 120 and/or chamber 125 can
couple or attach to various other components, including for example
a receiver (e.g., an upper receiver), a stock, a handguard, or any
other suitable component or accessory.
[0031] In various embodiments and with reference to FIGS. 2A-2D,
barrel 220 comprises a chamber 225. Chamber 225 comprises channel
226. Barrel 220 and chamber 225 may be a single piece (e.g., a
barrel comprising a barrel portion and a chamber portion) or an
assembly. Barrel 220 can define a cylindrical cavity having a
diameter (e.g., an internal diameter or ID). The diameter may be
any suitable size. Barrel 220 may also be any suitable length.
Chamber 225 can also define a cylindrical cavity having a diameter
(e.g., an internal diameter or ID). Chamber 225 may, also be any
suitable length. Channel 226 may be any suitable channel or groove
defined in the interior wall of chamber 225 (e.g., the wall
defining the interior cavity of chamber 225). Channel 226 may be
any suitable length that is shorter than the length of chamber 225.
Channel 226 may also be any suitable depth, size (e.g., volume),
and/or shape.
[0032] In various embodiments, a firearm comprising barrel 220,
chamber 225, and channel 226 may be any rotating bolt firearm,
including for example, an automatic or semi-automatic rifle (e.g.,
an AR-15/M-16 style rifle) chambered in any appropriate caliber
(e.g., .223 Remington/.556 Nato, .308 Winchester/7.62x51 Nato, and
the like). In this example, and with specific reference to FIG. 2D,
the cartridge may comprise a neck portion 221, a shoulder portion
222, and a body portion 223. Chamber 225 may have an appropriate
internal contour or profile to accept each of neck portion 221,
shoulder portion 222, and body portion 223 to position the
cartridge for activation, as shown in, for example, Section A-A of
FIG. 2A. Moreover, channel 226 may be appropriately formed in the
internal wall of the chamber (e.g., the wall that defines the
internal profile of the chamber) at an appropriate length to
pressurize an exterior surface associated with one or more of the
surfaces associated with neck portion 221, shoulder portion 222,
and body portion 223.
[0033] For example and as shown in FIG. 2A, Section A-A, channel
226 may be defined at such a length that the gas from an activated
cartridge pressurizes and applies an associated force to the
exterior surface associated with neck portion 221. However, channel
226 may be any suitable length shorter than the length of the
chamber. In this way, channel 226 may pressurize and apply an
associated force to any portion of the exterior surface of the
cartridge (e.g., neck portion 221, shoulder portion 222, and/or
body portion 223).
[0034] In another example, the case of a cartridge may have a
generally uniform profile (e.g., a 9 mm, .45-70 Government, and the
like). In this example, the case comprises a body portion, but no
neck or shoulder portion. As such, a chamber appropriately sized
for a case having a generally uniform profile may comprise channel
226 that is shorter than chamber 225 and that conducts pressure and
an associated force to the body portion of the case.
[0035] In various embodiments and with reference to FIGS. 3A-3D,
firearm 300 comprises a barrel 320 and a chamber 325 comprising one
or more channels 326. As described herein, barrel 320 and chamber
325 may be adaptable to any rotating bolt firearm now known or
hereinafter developed. However, by way of example, firearm 300 is
depicted in FIGS. 3A-3D as a gas piton operated AR-15/M-16 style
rifle capable of shooting any suitable caliber cartridge. As such,
in this example, firearm 300 may also comprise various other
components including, for example, an upper receiver 310, a
handguard 330, a lower receiver 340, a stock 350, an operating
system 360, a magazine 370 and/or the like.
[0036] In various embodiments and by way of example, firearm 300
may be loaded with cartridge 301, as shown in FIG. 3A. More
specifically, cartridge 301 can be advanced from magazine 370 by a
bolt carrier assembly 311 (carried in, for example, upper receiver
310) into chamber 325. Cartridge 301 may be activated in response
to providing an input to a trigger 341 (housed in, for example,
lower receiver 340). The input to trigger 341 actuates a firing
mechanism (e.g., a sear and firing pin) that activates cartridge
301, firing or propelling bullet 3018 from case 301A, as shown in
FIG. 3B. The activation of cartridge 301 may also cause an increase
in pressure in a portion of the volume defined by chamber 325, the
volume defined by the channel 326, and/or the volume defined by
barrel 320 (e.g., the volume near the breach end of the
barrel).
[0037] In various embodiments, the pressure increase can be
conducted through one or more channels 326. This pressure can be
applied to the outer surface of case 301A. The pressure applies an
associated force to the outer surface of case 301A. The force may
be directed based on the shape of channel 326 and/or the outer
profile of case 301A. For example, in the present example, the case
comprises a neck portion, a shoulder portion and a body portion.
Channel 326 may be shaped such that a pressure is applied to one or
more of the neck portion, shoulder portion and body portion.
[0038] For example, and with momentary reference to FIG. 2A.
Section A-A and FIG. 2D, channel 226 may be of any suitable length
to conduct pressure from an activated cartridge to the neck of the
case. The pressure applied to neck 221 may cause a force (e.g.,
perpendicular to the centerline of the barrel) and a force
generally parallel to the centerline of the barrel (e.g., toward
the stock of the gun) to be applied to the outer surface of the
neck.
[0039] With momentary reference to FIG. 2B, Section N-N and FIG.
2D, channel 226 may be of any suitable length to conduct pressure
from an activated cartridge to neck 221 and shoulder 222 of the
case. The pressure applied to neck 221 and shoulder 222 may
comprise a force (e.g., perpendicular to the centerline of the
barrel) and a force (e.g., parallel to the centerline of the
barrel) to be applied to the outer surface of neck 221 and shoulder
222. This force may be applied based on the shape of shoulder 222
and/or channel 226.
[0040] With momentary reference to FIG. 2C, Section R-R and FIG.
2D, channel 226 may be of any suitable length to conduct pressure
from an activated cartridge to neck 221, shoulder 222, and body 223
of the case. The pressure applied to neck 221, shoulder 222, and
body 223 may comprise a force (e.g., perpendicular to the
centerline of the barrel) and a force (e.g., parallel to the
centerline of the barrel) to be applied to the outer surface of
neck 221, shoulder 222 and body 223.
[0041] In various embodiments, the cartridge may have a generally
uniform body profile. Where the cartridge has a generally uniform
profile as discussed above, pressure would be applied to the body
causing a compressive force (e.g., perpendicular to the centerline
of the barrel) and a force (e.g., parallel to the centerline of the
barrel) to be applied to the outer surface of the body.
[0042] By way of continuing example and with reference to FIG. 3C,
bullet 301B travels from the breach end of barrel 320 to the muzzle
end of barrel 320. In response to the bullet passing an inlet of
operating system 360, operating system 360 is pressurized and
actuated. In response to operating system 360 actuating, an op-rod
361 strikes bolt carrier assembly 311 causing the bolt to rotate
and unlock from chamber 325. In response to the bolt unlocking from
chamber 325, the bolt carrier assembly 311 is pushed by operating
system 360 toward the butt of firearm 300, reducing the pressure in
chamber 325 and barrel 320. Case 301A is pulled from chamber 325 by
an extractor of bolt carrier assembly 311, as bolt carrier assembly
311 is pushed by operating system 360. With reference to FIG. 3D,
as bullet 301B passes through the muzzle end of barrel 320 and into
the atmosphere, the pressure in chamber 325 and barrel 320 are also
exhausted to the atmosphere. Case 301A is ejected from upper
receiver 310 as bolt carrier assembly 311 cycles.
[0043] In various embodiments and with reference to FIGS. 4A-4G, as
discussed herein, chamber 425 may comprise or otherwise define one
or more channels 426. Channel 426 may be of any suitable shape,
size, depth, width, and/or length. For example, channel 426 may
have a profile of any suitable shape including for example, a
triangular, circular, rectangular, uniform, and/or non-uniform
profile. Moreover, a chamber 425 may comprise a first channel 426
having a first volume and a second channel 426 having a second
volume. In various embodiments, the volume of first channel 426 may
be equal to, greater than, or less than the volume of second
channel 426.
[0044] In various embodiments, the one or more channels 426 may be
defined at any suitable location in the interior wall of chamber
425 defining the inner diameter of chamber 425. Channel 426 may be
configured to exert a pressure on the case of a cartridge.
[0045] In various embodiments, chamber 425 may comprise two or more
channels 426. Two or more channels 426 may be configured to provide
a uniform pressure on the outer surface of a case of a cartridge.
For example, two or more channels 426 may be positioned in chamber
425 substantially equidistantly around of the inner diameter of the
chamber, as shown in FIGS. 4B-4D. Two or more channels 426 may also
be positioned in chamber such that the pressure directed by the two
or more channels 426 are applied uniformly to the outer surface of
the case, but channels 426 are not spaced equidistantly from one
another, as shown in FIG. 4E.
[0046] In various embodiments, chamber 425 may comprise one or more
channels 426. One or more channels 426 may be configured to provide
a non-uniform pressure on the outer surface of a case. For example,
chamber 425 may comprise one channel 426 defined in the chamber
wall at any point along the diameter (e.g., the internal diameter
or chamber wall) of chamber 425, as shown in FIG. 4A. Chamber 425
may comprise two or more channels 426 defined in the chamber wall
at various points along the diameter of chamber 425 that are not
equidistant, as shown in FIG. 4F.
[0047] With reference to FIG. 40, chamber 425 may comprise one or
more channels 426A and one or more channels 426B. Channel 426A
and/or channel 426B may be various sizes, lengths, volumes, widths,
shapes and/or the like. Channel 426A and/or channel 426B may be
configured to provide a uniform pressure or a non-uniform pressure
to the outer surface of the case. For example, one or more channels
426A may have a volume or may be appropriately sized to conduct a
force from a pressure that is equal to the force or pressure
conducted by one or more channels 426B. One or more channels 426A
may also have a volume or may be appropriately sized to conduct a
force from a pressure that is not equal to the three or pressure
conducted by one or more channels 426B. In this way, one or more
channels 426A and one or more channels 426B may be arranged is any
suitable configuration to aid in the extraction of a case from
chamber 425.
[0048] In various embodiments, the channels defined in the chamber
may be configured to reduce the overall outward force applied
and/or pressure applied to the interior surface of the case in
response to a cartridge being activated. More specifically, the
channels may be configured to apply a pressure to the outer surface
of the case (when the cartridge is activated) to reduce or
counteract the pressure applied to the internal volume of the
cartridge. This external pressure may counteract any pressure or
equivalent force created by the activation of the cartridge
[0049] Thus, the chamber described herein provides a mechanism to
minimize operational failures of a rotating bolt firearm.
[0050] Benefits, other advantages, and solutions to problems have
been described herein with regard to specific embodiments.
Furthermore, the connecting lines shown in the various figures
contained herein are intended to represent exemplary functional
relationships and/or physical couplings between the various
elements. It should be noted that many alternative or additional
functional relationships or physical connections may be present in
a practical system. However, the benefits, advantages, solutions to
problems, and any elements that may cause any benefit, advantage,
or solution to occur or become more pronounced are not to be
construed as critical, required, or essential features or elements
of the inventions. The scope of the inventions is accordingly to be
limited by nothing other than the appended claims, in which
reference to an element in the singular is not intended to mean
"one and only one" unless explicitly so stated, but rather "one or
more." Moreover, where a phrase similar to "at least one of A, B,
or C" is used in the claims, it is intended that the phrase be
interpreted to mean that A alone may be present in an embodiment, B
alone may be present in an embodiment, C alone may be present in an
embodiment, or that any, combination of the elements A, B and C may
be present in a single embodiment; for example, A and B, A and C, B
and C, or A and B and C. Different cross-hatching is used
throughout the figures to denote different parts but not
necessarily to denote the same or different materials.
[0051] Systems, methods and apparatus are provided herein. In the
detailed description herein, references to "one embodiment", "an
embodiment", "an example embodiment", etc., indicate that the
embodiment described may include a particular feature, structure,
or characteristic, but every embodiment may not necessarily include
the particular feature, structure, or characteristic. Moreover,
such phrases are not necessarily referring to the same embodiment.
Further, when a particular feature, structure, or characteristic is
described in connection with an embodiment, it is submitted that it
is within the knowledge of one skilled in the art to affect such
feature, structure, or characteristic in connection with other
embodiments whether or not explicitly described. After reading the
description, it will be apparent to one skilled in the relevant
art(s) how to implement the disclosure in alternative
embodiments.
[0052] Furthermore, no element, component, or method step in the
present disclosure is intended to be dedicated to the public
regardless of whether the element, component, or method step is
explicitly recited in the claims. No claim element herein is to be
construed under the provisions of 35 U.S.C. 112, sixth paragraph,
unless the element is expressly recited using the phrase "means
for." As used herein, the terms "comprises", "comprising", or any
other variation thereof, are intended to cover a non-exclusive
inclusion, such that a process, method, article, or apparatus that
comprises a list of elements does not include only those elements
but may include other elements not expressly listed or inherent to
such process, method, article, or apparatus,
