DETAILED DESCRIPTION OF THE INVENTION
[0045] Citing the teaching of FIG. 1, A drawing is a form of muzzle brake 1 utilizing an end plate being an integral part of the body of the muzzle brake.
[0046] Citing the teaching of the preferred embodiment of the FIG. 2, B drawing disclosing a cross-sectional view for a muzzle brake 1 being externally and internally cylindrical in shape and revealing a gas capture chamber 3 superior in size to the bore 75, that features a threaded 90 gas capture chamber insert end plate 2 exhibiting a plurality of radially skewed (11, FIG. 3, B) precision angle 10 vent ports 4, introduced at a 105 degree angle 10 relative to the center line 121 of the bore of the firearm and the direction of the path (131, FIG. 9,A) of the projectile 100, reveals and define distinctly, and for clarity, Major truncated socket forms 5 at and in conjunction with said 105 degree angle 10 vent ports introduced substantially into said gas capture chamber 3 end plate 2 face wall 8 of the threaded 90 said gas capture chamber 3 insert end plate 2.
[0047] A muzzle brake 1 being externally and internally cylindrical in shape and revealing a gas capture chamber 3 that features and exhibits a plurality of radially skewed (11, FIG. 3, B), precision angle 10 introduced vent ports 4, at said 105 degree angle 10 relative to the center line 121 of the bore of the firearm and the direction of said path (131, FIG. 9, A) of said projectile 100, reveals and define distinctly, and for clarity, Minor truncated socket forms 6 at and in conjunction with said 105 degree angle 10 vent ports 4. The muzzle brake 1 is internally threaded 80 for attachment to any appropriately externally threaded 81 muzzle end of a firearm barrel 70 of compatible size and caliber and is thus an attachment and accessory that can be attached or removed from the firearm. The gas capture chamber 3 within said muzzle brake 1 captures the high pressure gas acting as a column of fluid that is forced into the said gas capture chamber 3. This is the First Event acted on by said muzzle brake 1 in the chain of events relating to the Internal Ballistics of a firearm.
[0048] The preferred embodiment of said muzzle brake 1 invention discloses the said gas capture chamber 3 that features a threaded 90 gas capture chamber, insert end plate 2 exhibiting a plurality of radially skewed (11, FIG. 3, B), precision angle 10 vent ports 4. Said vent ports 4 are by design introduced at a said 105 degree angle 10 relative to the center line 121 said bore 75 of the firearm and in the direction of the path (131, FIG. 9, A) said projectile 100. Said vent ports 4 at said 105 degree angle 10 reveal and define said Major truncated socket forms 5 at and in conjunction with said 105 degree angle 10 vent ports 4 substantially introduced into the said gas capture chamber 3 end plate 2, internal face wall 8 of the threaded 90 said gas capture chamber 3 insert end plate 2. Alternate design of said vent ports 4 at said 105 degree angle 10 are to be contemplated in this comprehensive Physics teaching of muzzle brake Dynamics as to, The Study of Motion: The branch of mechanics that deals with motion and the way in which forces produces this motion.
[0049] Said vent ports 4 at said 105 degree angle 10 can by design be introduced at any angle from an angle of 90 degrees up to an angle of 135 degrees towards the breech of the firearm relative to said center line 121 of the bore 75 of the firearm and the direction of the path (131, FIG. 9, A) of said projectile 100. The preferred embodiment of the muzzle brake 1 invention discloses the said gas capture chamber 3 that distinctly and for clarity exhibits a plurality of radially skewed (11, FIG. 3, B), precision angle 10 introduced vent ports 4 at said 105 degree angle 10 reveal and define Minor truncated socket forms 6 at and in conjunction with said 105 degree angle 10 vent ports 4.
[0050] Said Minor truncated socket forms 6 preferably fails total penetration into the said gas capture chamber 3 interior wall thereby exhibiting vent ports 4 at said 105 degree angle 10 with a nozzle shaped truncated socket form 6 at the internal diameter interface with said gas capture chamber 3. Said Minor truncated socket forms 6 can by design penetrate in depth by varying amounts into said gas capture chamber 3 at the internal diameter interface, and can be on the order of 10 percent penetration, and up to 99.9 percent penetration at the internal diameter interface of said gas capture chamber 3.
[0051] The alternate monolithic embodiment FIG. 3, A with a barrel blend form 20 of the muzzle brake 25 invention discloses the said gas capture chamber 3 that first captures the highly compressed column of Atmosphere gas in the firearm bore 75 and said gas capture chamber 3 as it proceeds the projectile 100 prior to the projectile 100 entering into the said gas capture chamber 3 of said monolithic embodiment muzzle brake 25. Whereas this is the beginning of the first event, in the chain of events that reduce recoil and muzzle rise in the firearm.
[0052] Citing FIG. 4, the alternate embodiment of the muzzle brake discloses a cross-sectional view of the firearm barrel with integral muzzle brake 25, featuring a monolithic embodiment and being in a cylindrical form with said gas capture chamber 3, with projectile 100 beginning to exit the firearm barrel bore 75. The firearm muzzle brake 25 accomplishes a series of events that first captures the highly compressed column of Atmospheric gas preceding the projectile 100 prior to said projectile 100 passing through the said gas capture chamber 3 of said muzzle brake 25.
[0053] Wherein the highly compressed column of Atmospheric gas preceding the projectile 100 has attained a high pressure of approximately 20,000 pounds per square inch, and has nearly equalized with the hot high pressure expanding gas in the firearm barrel bore 75, that is propelling the projectile 100 forward, and acts within the said gas capture chamber 3 by impacting the said gas capture chamber 3 end plate wall 8 and is being restricted by the orifice 7, and imparts substantial energy to the end plate wall 8. This high pressure gas is then diverted into said Major truncated socket forms 5 and out exhaust port vents 4 at said 105 degree angle 10 resulting in more energy being imparted to the muzzle brake thereby reducing recoil. The following remainder of this highly compressed column of atmospheric gas is then forced into and acts upon the said Minor truncated socket forms 6 and forced out exhaust port vents 4 at said 105 degree angle 10 imparting additional energy in the forward direction further reducing the recoil of the firearm.
[0054] Citing FIG. 5 The Second Event now follows; within 0.0012 of a second the projectile 100 passes through the said gas capture chamber 3 as the hot high pressure expanding gas in the firearm bore 75 propels the projectile 100 forward and acts upon said gas capture chamber 3 by impacting the said gas capture chamber 3 said end plate wall 8 and being restricted by the orifice 7. The second and more substantial mass and energy of the hot high pressure gas following the projectile is forced into the Major truncated socket forms 5 and is expelled from the vent ports 4 at said 105 degree angle 10 and then the following hot high pressure gas is forced into and acts upon said Minor truncated socket forms 6 and out exhaust port vents 4 at said 105 degree angle 10 imparting force in the forward direction thus further reducing the recoil of the firearm.
[0055] The Third Event now follows; within 0.00005 of a second, the projectile 100 now exit's the muzzle brake orifice 7 end plate (2 FIG. 2, B). A short time after this event, the firearm barrel bore 75 and the muzzle brake 25 gas capture chamber 3 and exhaust ports 4 have exhausted all the hot high pressure gas and with completion of this event, due to the inertia of the hot high pressure gas there now exists, “a Partial Vacuum” in the firearm barrel bore 75 and in the muzzle brake 25 and in the vent ports 4. After this, a reverse flow of Atmospheric gas is pulled into the firearm barrel bore 75, at a high rate of speed approaching mach 2.5 passing through vent ports 4 at said 105 degree angle 10 and acting on said Minor truncated socket forms 6 and through the vent ports 4 at said 105 degree angle 10 and acting on said Major truncated socket forms 5 and through the orifice 7 to a lesser extent. The many vent ports 4 at said 105 degree angle 10 offer substantially less resistance, to the Atmospheric gas flow into the muzzle brake 25 with said gas capture chamber 3 and firearm barrel bore 75, than does the caliber specific orifice. At this time the Atmospheric gas being pulled into the muzzle brake 25 and the firearm barrel bore 75 through the vent ports 4, said Minor truncated socket forms 6, said Major truncated socket forms 5, and orifice 7, passing through the gas capture chamber 3 acts to impart energy in a forward direction to the truncated socket forms 5 and to the muzzle brake and firearm thus being the Third Event that further reducing the recoil.
[0056] Citing FIG. 8, A THROUGH FIG. 8, E in a firearm not equipped with said muzzle brake one must realize that instability is induced in projectile 100, by the movement of the firearm barrel 70 which occurs during recoil and adds to inaccuracy in the flight path 131 of projectile 100 as it leaves the bore 75 at the muzzle end of the firearm.
[0057] Citing FIG. 9, A THROUGH FIG. 9, D a firearm barrel equipped with said muzzle brake 1 of the present invention is stabilized, to the extent that the induced wobble of the centerline 141 of said projectile 100 is very significantly reduced and accuracy is improved.
[0058] Citing FIG. 5, On consideration of findings, is the belief that, the projectile 100, flight path 131 is stabilized on exiting the muzzle brake 25 orifice 7, and is influenced by orifice 7, and the 60 degree included angle chamfer 9. This small distance of projectile flight path 131 through orifice 7 and 60 degree chamfer 9 has the effect of realigning and damping the minute wobble of the projectile axis 141 of projectile 100 upon leaving the muzzle brake orifice 7, 60 degree included angle chamfer 9.
[0059] Citing FIG. 8 A THROUGH FIG. 8 E Depicting a firearm barrel 70, without a muzzle brake attached.
[0060] FIG. 8 A Depicting initiation of firing before any movement has begun, the centerline 141, of projectile 100, is aligned with the centerline 121 of the firearm bore 75, and with the intended flight path 131 of projectile 100.
[0061] FIG. 8 B As projectile 100 begins to emerge from firearm barrel 70, exhibiting the effect of recoil and barrel rise, projectile 100, centerline 141, is still aligned with the centerline 121 of the bore 75, and the flight path 131, of projectile 100.
[0062] FIG. 8 C As projectile 100 exits the firearm barrel 70, exhibiting the effect of recoil, the base of the projectile 100 will be forced up and out of alignment with the centerline 121 of the bore 75 of the firearm, and deflected from the intended flight path 131, of the projectile 100, so that the centerline of the projectile 141, is no longer aligned with the flight path 131, introducing instability in the projectile 100 and inaccuracy in the flight path 131.
[0063] FIG. 8 D Firearm barrel 70, now exhibits the continuing effects of recoil, whereas the hot high pressure gas is being expelled form the bore 75, of the firearm, whereby the ensuing turbulence exerts asymmetrical force to the base of projectile 100 causing further disruption to the stability of the projectile 100 and causing the centerline of the projectile 141 to be pushed further out of alignment with the intended flight path 131 and greater inaccuracy.
[0064] FIG. 8 E As projectile 100, moves further from the firearm barrel 70, the gyroscopic effect of the spin imparted to the projectile 100, by rifling in the firearm bore 75 will begin to stabilize the projectile after going through several oscillations.
[0065] Citing FIG. 9 A THROUGH FIG. 9 D With the current muzzle brake 1 attached to the firearm barrel 70, very little movement due to recoil is imparted to the firearm barrel 70, and thus the base of projectile 100 is not pushed off the centerline of the flight path 131 to nearly as great an extent thereby not disrupting the intended flight path 131 of the projectile 100 and improving the accuracy of the system.
[0066] All of the combined actions described and hereafter named, The First Event, The Second Event, and The Third Event, utilizes a percentage of the captured kinetic energy from each event to reduce recoil and muzzle rise, that would be lost by direct venting in prior art inventions as they do not utilize the novel and substantial high pressure gas controlling functions of the caliber specific orifice 7 end plate 2 with Major truncated socket forms 5 and the Minor truncated socket forms 6 of the current invention. In the Science of Internal Ballistics one must with due diligence, and research, identify all the various components, actions, events, and forces in play propelling a projectile 100 out of the barrel 70 of a firearm and those forces that can be used to reduce or eliminate recoil, muzzle rise and movement.
[0067] In a society of gentlemen inventors it will be understood that embodiments of the present invention include, but are not limited, to the scope of the muzzle brake 1 embodiment herein described, designed, constructed, and illustrated in the drawings. Further variations and improved modifications of the above described muzzle brake 1 invention are to be contemplated, and applied without departing from the advanced technological aspects of the present invention.
