Brief Patent Description - Full Patent Description - Patent Application Claims
CROSS-REFERENCE TO RELATED APPLICATIONS [0001]This application claims the benefit of the filing of U.S. Provisional Patent Application Ser. No. 60/808,319, entitled "Firearm Barrel Vibrational Stabilizing Device", filed on May 24, 2006, and the specification thereof is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002]1. Field of the Invention (Technical Field) [0003]The present invention is a device and system to dampen or control barrel vibrations which occur when a firearm, particularly a rifle, is fired. [0004]2. Background Art [0005]Note that the following discussion refers to a number of publications and references. Discussion of such publications herein is given for more complete background of the scientific principles and is not to be construed as an admission that such publications are prior art for patentability determination purposes. [0006]When firing a projectile through a firearm, vibrations in the firearm barrel are caused, which results in lower targeting accuracy and less uniformity from shot to shot. FIG. 1 schematically depicts vibrations 12 of a segment of barrel 20. The vibrations typically comprise standing waves, with certain locations on the barrel corresponding to maximum amplitudes of the standing waves, and other locations, or nodes, corresponding to minimum standing wave amplitudes. The standing wave frequency and maximum amplitude are typically highly dependent on the specific design, dimensions, and materials of the firearm. A description of barrel vibrations may be found in U.S. Pat. No. 2,372,568, incorporated herein by reference. SUMMARY OF THE INVENTION (DISCLOSURE OF THE INVENTION) [0007]The present invention is an apparatus for controlling vibrations of a firearm barrel, the apparatus comprising a post comprising an at least partially threaded interior cavity, the post attached to the barrel at a location for controlling vibrations of the barrel, and a threaded bolt screwed into the cavity, the bolt at least partially securing the firearm stock to the barrel. The location is preferably approximately a point of maximum vibration of the barrel. The barrel preferably comprises a recess for receiving the post. The post is preferably hard soldered or welded to the barrel, or is optionally integrally formed with the barrel. The tension of the bolt is preferably adjustable. The barrel is preferably substantially free to vibrate from approximately the location of the bolt to a muzzle of the barrel. The bolt preferably comprises a hole for receiving a sling or a sling swivel post. The apparatus preferably further comprises an escutcheon for receiving the bolt and securing the stock to the barrel. The escutcheon preferably comprises a metal or a hard wood. [0008]The present invention is also a method for controlling vibrations of a firearm barrel, the method comprising the steps of attaching a post comprising an at least partially threaded interior cavity to a firearm barrel at a location suitable for controlling vibrations of the barrel, inserting a bolt through an opening of a firearm stock, and screwing the bolt into the cavity, thereby at least partially securing the stock to the barrel. The attaching step preferably comprises welding or hard soldering the post to the barrel. The location is preferably approximately a point of maximum vibration of the barrel. The method preferably further comprises the step of forming a recess in the barrel for receiving the post. The attaching step optionally comprises integrally forming the post during manufacture of the barrel. The method preferably further comprises the step of adjusting a tension of the bolt. The method preferably further comprises the step of attaching a sling or sling swivel post to the bolt. The inserting step preferably comprises inserting the bolt through an escutcheon inserted in the stock. The method preferably further comprises the step of shaping the escutcheon during shaping of the stock. The method preferably further comprises the step of permitting the barrel to vibrate substantially freely from the location of the post to a muzzle of the barrel. [0009]An object of the present invention is to dampen vibrations of a firearms barrel during firing. [0010]An advantage of the present invention is improved firearm accuracy and uniformity from shot to shot. [0011]Another advantage of the present invention is that for a rifle the device is preferably mounted to the barrel through the rifle's wooden forearm or stock, where the strongest vibrations typically occur. [0012]Other objects, advantages and novel features, and further scope of applicability of the present invention will be set forth in part in the detailed description to follow, taken in conjunction with the accompanying drawings, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims. BRIEF DESCRIPTION OF THE DRAWINGS [0013]The accompanying drawings, which are incorporated into and form a part of the specification, illustrate several embodiments of the present invention and, together with the description, serve to explain the principles of the invention. The drawings are only for the purpose of illustrating a preferred embodiment of the invention and are not to be construed as limiting the invention. In the drawings: [0014]FIG. 1 is a schematic showing standing wave vibrations of a section of a firearm barrel; [0015]FIGS. 2a-2c show an exploded cross sectional view of a segment of an embodiment of the present invention; and [0016]FIGS. 3a-3e depict multiple methods of fastening the stabilizing post to a section of the firearm barrel. DESCRIPTION OF THE PREFERRED EMBODIMENTS Best Modes for Carrying Out the Invention [0017]The present invention is a device for dampening, stabilizing, or controlling barrel vibrations caused by firing a firearm, particularly but not limited to a rifle. The present invention preferably forces the barrel to vibrate approximately the same from shot to shot. It also preferably controls vibrational nodes of the barrel so that different weight projectiles having various velocities may be used with more accuracy to a given point of aim. [0018]Stabilizer post 10 of the present invention is preferably located at a position of maximum vibration of firearm barrel 20 as shown in FIG. 1. The location providing optimal vibration control may be different for any particular combination of firearm and ammunition and may be determined theoretically, by simulations, or empirically. One or more devices may alternatively be located at nodes or other positions along the barrel in order to provide desired results.
