I ANTI-RECOIL GUN BARRELS Filed Dec. 7. 1954 1N VENTOR 17/5- John F. M mr 2,842,024 v I ANTI-RECOIL GUNBARRELS 7 John F. MuttenPendleton, Oreg.
I Ap lication December 7,1954,"SerialNo.473,65z.
1 Claim. (CI. 89-14) I This invention relates to-new and useful improvements and structural refinements in firearms,particularly rifles,
and the like, and the principal object of the invention is to effectively counteract the customary recoil occurring when the gun is fired and to simultaneously counteract the so-called muzzle flip, or tendency of the'muzzle to rise upon firing.
The above object is attained by the provision'of antirecoil means including, inter alia, the formation of an enlarged gas chamber at the muzzle of the gun barrel, the gas chamber being equipped at its front end with a bullet exit which also serves to form a gas trap in the front end portion of the gaschamber, the chamber having a plurality of gas outlet openings in communication therewith, so that exploded gases following the bullet through the barrel enter the gas chamber and cause a forward, recoil counteracting impact in the gas trap prior toftheir exit through the gas outlet openings.
Another feature of the invention involves the location of the gas outlet openings in a predetermined arrangement at the top of the gas chamber, whereby exploded gas escaping through these openingsurges the muzzle of the barrel downwardly to counteract so-called muzzle A further feature of the invention resides in ,the
3 provision of aplurality of ventilating apertures in the upper portion of the muzzle portion of the gun barrel itself, which apertures coact with the aforementioned gas chamber, gas trap and gas outlet openings in properly controlling the flow of exploded gases through the gun. I A still further feature of the invention resides in I arranging the various gas outlet openings and ventilating apertures so that the gases escaping therefrom do not obstruct the operators vision or flow into the vicinity of his face.
' Some of the advantages of the invention lie in its simplicity of construction, efiiciency and dependability of operation and in its adaptability for either integral embodiment in, or an attachment to existing guns.
With the above more important objects and features in view and such other objects and features as may "become apparent as this specification proceeds, the invention resides in the arrangement of parts and details of construction substantially as shown in the accompanying drawing, wherein like characters of reference are escaping therethrough are directed rearwardly. By virtue" of the openings 19 and apertures 21 being laterally or ice similar to that shown in Figure 1, but invention embodied integrally in the .gun barrel.
Referring now to the accompanying drawing in detail,
particularly Figures 1-5 inclusive, the gun barrel is designated by the numeral 10, including the bore 11, muzzle' 12 and the usual frontsight 13.
The front end portion of the. barrel 10 is diametrically reduced and screw-threaded as indicated at 14 to receive an internally.screw threaded rear end portion 15' of a substantially cylindrical extension 15, it being noted that this extension corresponds in its overall outside.
diameter with the outside diameter of the barrel so that it does not in any way interfere with or obstruct the operator's vision.
with a re-entrant bullet exit 17 which is spaced-longiexit 17 results in the formation of an annular gas trap or annular brake head 18 in the front end portion of the gas chamber 16, so that exploded gases following the bullet through the bore 11 enter the chamber 16 and produce a forward impact in the gas'trap 18 'to counteract recoil.
The extension 15 is provided at the top thereof with a plurality of rows of gas outlet openings 19, these rows of openings being spaced laterally or circumferentially to opposite sides of the vertical medial line of the extension and the openings in each row having axes radially disposed. The openings 19 communicate with the gas chamber 16 to facilitate escape of exploded gases therefrom and, of course, the size or diameter of the openings is such as to properly control the flow of the gas escaping therethrough and produce the required amount of forward force or impact in the gas trap 18 to counteract recoil. Moreover, it is to be noted that since the openings 19 are provided onlyin the upper portion of the gas chamber 16, the escape of gasestherethrough will urge the muzzle downwardly to effectively counteract muzzle flip.
Y A relatively small drain aperture or opening 20 is provided at the bottom of the extension 15 in communication with the gas trap 18, as will be clearly apparent.
The invention also contemplates the provision of rows to opposite sides of the vertical medial line of the barrel and communicating with the bore 11, as is best shown in Figures 3 and 4. Although the axes of'the apertures 21 are radially disposed as shown in Figure 3, they are also rearwardly inclined as shown in Figure 4, so that gases circumferentially offset from the vertical medial line of the extension 15 and barrel 10, the escaping gases are also laterally directed so that they do not obstruct o interefere with the operators vision.
The modified form of the invention shown in Figure 6 is embodied integrally in the construction of the gun bar- Figure 6 is a fragmentary longitudinal sectional view,
rel rather than being an attachment thereto, as in the embodiment already described. In this form the gun barrel 10a, having a bore 11a, has a counterbored muzzle por tion affording a gas chamber 16a therein, the gas outlet openings of the latter being shown at 19a.
The outer end portion of the chamber 16a is internally screw-threaded as indicated at 22 to receive a removable plug 23, the latter being formed with abullet exit 17a which extends into the chamber 16a and affords a gas trap 18a therein. A drain opening 20a is provided in communication with the gas trap 18a and the outer end por- Patented July 8, 1958 illustrating the The extension 15 affords therein anlenlarg ed gas chamber 16 and the front end of the extension is provided.
3 tion of the plug 23 is provided with a suitable socket 24 to receive a wrench, or the like, (not shown) to facilitate tightening or loosening of the plug.
It is to be understood that in this form of the invention the gun barrel lila is also provided with ventilating apertures such as those shown at 21 in the embodiment previously described.
While in the foregoing there have been shown and described the preferred embodiments of the invention, various modifications may become apparent to those skilled in the art to which the invention relates. Accordingly, it is not desired to limit the invention to this disclosure and various modifications may be resorted to, such as may lie within the spirit and scope of the appended claim.
What is claimed as new is:
An anti-recoil gun barrel having a muzzle portion provided only at the top thereof at opposite sides of its axis with longitudinally extending rows of rearwardly inclined ventilating apertures, said muzzle portion also being provided forwardly of said apertures with an enlarged gas chamber having a lateral wall provided only in its upper portion with rows of gas outlet openings, the side and bottom portions of said muzzle portion and of said lateral wall of said gas chamber being imperforate, and a bullet exit provided at the outer end of and re-entrant in said gas chamber coaxially with the bore of the barrel, said bullet exit affording an annular brake head in the front end portion of, said gas chamber.
