STATEMENT AS TO RIGHTS TO INVENTION MADE UNDER FEDERALLY SPONSORED
RESEARCH AND DEVELOPMENT
[0004] Not Applicable.
BACKGROUND OF INVENTION
[0005] 1. Field of Invention This invention relates to a Recoil,
Sound and Flash Suppressor such as would be usable for a firearm
such as, but not restricted to, a rifle.
[0006] 2. Background Information
[0007] Firearms, including but not limited to rifles, cause a
recoil when fired due to the violent release of combustion gases.
As will be seen from the subsequent description, the present
invention successfully suppresses recoil adequately enough to
comfortably shoulder-fire certain firearms such as, but not limited
to .50 caliber rifles that could not be shoulder-fired comfortably,
as well as providing significant noise suppression for the shooter
and flash suppression for combat situations.
SUMMARY OF THE INVENTION
[0008] The embodiment of this invention, a Recoil, Sound and Flash
Suppressor overcomes the present ineffectiveness in attached muzzle
devices by using combustion gas thrust through the vents to
effectively negate what escapes the muzzle while at the same time
diminishing sound and flash through the unique geometry formed by
the machining of said vent ports, which heretofore provides a
sequential dispersant of the aforementioned gases.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] FIG. 1 illustrates a rifle with a Recoil, Sound and Flash
Suppressor machined as a permanent part of it as well as a rifle
with threads machined on the barrel for use with the present
invention in its removable embodiment.
[0010] FIG. 2 illustrates how the removable embodiment of the
Recoil, Sound and Flash Suppressor is attached to a firearm.
[0011] FIGS. 3 and 4 illustrate the how the present invention works
to suppress recoil, sound and flash.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Referring to FIG. 1, the top illustration shows a large
caliber rifle 2 with the fixed or permanent embodiment of the
Recoil, Sound and Flash Suppressor 3 machined to the rifle barrel 4
as one part. The bottom illustration on FIG. 1 shows how the
removable embodiment of the Recoil, Sound and Flash Suppressor 1
with internal threads machined in the end of it can be attached to
rifle barrel 5 through the use of threads 6 machined on to the end
of barrel 5.
[0013] Referring to FIG. 2, the Recoil, Sound and Flash Suppressor
1 is attachable to rifle 2, or other firearm, with the use of
internal threads 7 and hex area 8 which allows a wrench to tighten
or loosen the removable Recoil, Sound and Flash Suppressor 1 and
attach it to barrel 5 which has threads 6 machined on the end of
it. Ports/holes 9 are machined to allow controlled escape of
pressurized combustion gases from within the newly designed
removable Recoil, Sound and Flash Suppressor 1 and the permanently
attached Recoil, Sound and Flash Suppressor 3. Recoil, Sound and
Flash Suppressor 1 and Recoil, Sound and Flash Suppressor 3 are the
same with the exception that Recoil, Sound and Flash Suppressor 3
is permanently attached and Recoil, Sound and Flash Suppressor 1 is
removable by adding threads to both the Recoil, Sound and Flash
Suppressor 3 and rifle barrel 4. With that in mind, all further
references in this Application to Recoil, Sound and Flash
Suppressor 1 and Recoil, Sound and Flash Suppressor 3 shall be
stated as Recoil, Sound and Flash Suppressor 1.
[0014] FIG. 3 illustrates a cross section and blow-up of the
internal structure of the Recoil, Sound and Flash Suppressor 1. The
importance of this design is that the exact calculation of the
diameter of the ports/holes 9, the exact angle at which they are
machined in to the newly designed Recoil, Sound and Flash
Suppressor 1, and the exact spacing, provides an overlapped
scalloped area 11 on the inside of the newly designed Recoil, Sound
and Flash Suppressor 1.
[0015] At each row of ports 9 which encircles the Recoil, Sound and
Flash Suppressor 1, there is formed on the inside bore a cavity
which captures the combustion gas that follows the bullet 10 as it
travels along barrel 5 (barrel 4 for the permanently attached
embodiment of the current invention). These cavities on the inside
of the Recoil, Sound and Flash Suppressor 1 greatly increase the
amount of gas that is captured and redirected out of ports 9 and
thus increases the recoil, Sound and flash reduction of the weapon
2. The diameter of these ports 9, the angle at which these ports 9
are bored and the spacing of these ports 9 is a precise calculated
value based on the caliber of the weapon for which Recoil, Sound
and Flash Suppressor 1 is being designed. The Recoil, Sound and
Flash Suppressor 1 would be adapted to weapons using different
caliber ammunition by taking the figures used for a .50 caliber
ammunition and precisely scaling them down for a weapon using
smaller caliber ammunition and scaling them up for a weapon using
larger caliber ammunition.
[0016] FIG. 4 gives a look at the Recoil, Sound and Flash
Suppressor 1 from an end view, a cross section view, and an
internal view and shows the measurements and angles of the Recoil,
Sound and Flash Suppressor 1.
"a" is the angle at which the ports 9 are machined; "b" is the
linear spacing for the ports 9; "c" is the circumference angle
around the Recoil, Sound and Flash Suppressor 1; and "d" is the
diameter of ports 9.
[0017] The resulting scalloped area 11 will capture the escaping
combustion gasses and redirect the gasses out ports 9 at an angle
away from the end of barrel 5 and slightly toward the shooter.
[0018] The ratios of these values to each other would change
depending on the caliber of the ammunition. As stated above, the
Recoil, Sound and Flash Suppressor 1 would be adapted to weapons
using different caliber ammunition by scaling up or down to match
the size of the weapon and the ammunition it uses.
[0019] Description of Operation:
[0020] In FIG. 3, a bullet 10 is shown being fired through barrel
4. The resulting combustion gases as the bullet 10 exits the
Recoil, Sound and Flash Suppressor 1 would be directed out ports 9
at an angle back toward the breech. The expulsion of the combustion
gases in this direction redirects the backward force of the firearm
in a progressive sequential manner as the gas is vented out ports 9
instead of back through the barrel 4 of the firearm. Most existing
recoil suppressors direct the combustion gases out at a 90 degree
angle.
[0021] Although the description above contains many specificities,
these should not be construed as limiting the scope of the
invention, but as merely providing illustrations of some of the
preferred embodiments of the invention.
[0022] It will be obvious to those skilled in the art, that
modifications may be made to the embodiments of the invention
described above without departing from the scope of the present
invention. Thus, the scope of the invention should be determined by
the appended claims in the formal application and their equivalents
rather than by the examples given.
