Abstract
A mounting device for the purpose of mounting various sighting apparatus on the raised vented rib of shotguns and various other weapons is disclosed. A mounting device that attaches to any suspended rail is disclosed. The device is characterized by a channeled piece of material designed to customly accept a flat plate of material within the inner surface walls of the extending arms of said channel and connected together by screws through mating holes to create a clamp-like device when the flat plate of material is placed beneath the suspended rail and the channel piece is placed on top of the suspended rail and mated to the flat plate and drawn together with screws to create a mounting surface on top of the suspended rail for use with various sighting apparatus. The device is affixed with centering and alignment means and braces that allow for adjusting to the various distances between the suspending posts of the rail, for stabilizing and for recoil absorption. The device can be formed, shaped and otherwise configured to work in conjunction with other practical mounting methods.

Description
Background of the Invention
Shotguns and other various weapons are often manufactured with what is known as a vented rib, which is a suspended rail that is centered on and extends the length of the barrel of said weaponry. The vented rib limits the means to support various sighting apparatus that are designed to be mounted or maintained with a longer relief or distance from a user's eye. In many instances, because of this limitation, relief oriented sighting apparatus are mounted too close to the user's eye and become awkward, inoperable or at best difficult to use with their intended precision. This invention then relates to the making of a more effective and desirable way to mount the various sighting apparatus that are currently manufactured for use with an intended longer eye relief. This invention can be affixed with and used in conjunction with many practical mounting means.
Although the features of this invention which are believed to be novel are set forth in the claims, details as to its organization and method of operation, together with the further objects and advantages thereof, may be best understood through reference to the following description taken in connection with the accompanying drawings, wherein:
Brief Description of Drawings
FIG. 1 is an exploded perspective view consisting of the mounting system as it would appear to mount on the raised vented rib of a shotgun barrel;
FIG. 2 is an exploded perspective view consisting of the mounting system as it would appear when mounted on the raised vented rib of a shotgun barrel along with a dovetail scope ring attachment exploded therefrom.
Description of the Preferred Embodiments
Referring now to the drawings in detail, wherein like numerals indicate like elements throughout the several views, FIGS. 1 and 2 illustrate a mounting device for use with sighting apparatus on the raised vented rib, generally designated by the numeral 12, of various weapons. Device attaches to raised vented rib 12 by four threaded screws 14, 16, 18 and 20 as they pass through countersunk clearance holes 22, 24, 26 and 28 in mounting base 30 and are received by the four threaded holes 32, 34, 36 and 38 in clamping plate 40 and then drawn tight against raised vented rib 12. Mounting base 30 is a channeled piece of material, preferrably a non-corrosive metal, with a flat surface 42 and two extended arm surfaces 44 and 46. Mounting base 30 has at least four countersunk clearance holes 22, 24 26 and 28 on its flat surface 42 and four threaded holes 50 and 52 at the four outer corners 56, 58, 60 and 62 on the arm surfaces 44 and 46 that accept four threaded screws 64, 66, 68 and 70 for centering and adjusting mounting base 30 on raised vented rib 12. Extended arm surfaces 44 and 46 also have threaded holes 72 and 74 for the purpose of adapting extension and recoil braces 76 and 78, which help stabilize and reduce recoil shock to the various sighting apparatus which can be attached to mounting base 30 by extending in either direction and bracing against the raised vented rib carriage post 80 which elevates raised vented rib 12 from the barrel 82 of the weapon. Clamping plate 40 is a flat plate of metallic material with four threaded holes 32, 34, 36 and 38 shaped to fit beneath mounting base 30 and align with and accept the four threaded screws 14, 16, 18 and 20 as they pass through the countersunk clearance holes 22, 24, 26 and 28 on the flat surface 42 of mounting base 30. The extension braces 76 and 78 are angle shaped of a metallic material and are characterized by a long slot 84 in the center of the flat wall 86 which allows them to extend or retract after being attached to the two extended arm surfaces 44 and 46 of mounting base 30 by two threaded screws 88 and 90. The angled flat surfaces 92 and 94 of recoil braces 76 and 78 fit between raised vented rib 12 and weapon barrel 82 and adjust along slot 84 to brace against raised vented rib carriage post 80.
Whereas in FIG. 1, mounting base 30, clamping plate 40 and extension recoil braces 76 and 78 create the main structure of a mounting base in FIG. 2. The mounting base 30 is shown with a standard dovetail scope ring attachment base 96 which can be adapted to the flat surface 42 of mounting base 30 and can then be used in conjunction with standard and readily available scope ring clamps. The dovetail scope ring attachment base 96 can be mounted to the flat surface 42 of mounting base 30 by passing threaded screws 98 and 100 through clearance holes 102 and 104 in dovetail scope ring attachment base 96 and secured to mating threaded holes 106 and 108 in center of flat surface 42 of mounting base 30.
It is obvious that a new mounting system for sighting apparatus on raised vented rib weapons is hereby created and can be a valuable accessory used by sportsmen, shooters, etc. to get full benefit from relief oriented sighting apparatus currently available.
It should be understood that the specific embodiments of the invention herein disclosed are of a descriptive rather than a limiting nature, and that various changes, combinations, substitutions or modifications may be employed in accordance with these teachings without departing either in spirit or scope from this invention in its broader aspects.
