Abstract:
A gun sighting kit (8) and a method for gun sighting are preformed by placing a clear sheet (12) having a concentric circular graph (10) over a cluster of shots (32) on a target (28) that need only have a center location (30). A center (16) of the concentric circular graph has a hole (16′) through which a center (36) of the shot cluster is marked. The kit (8) also includes a square grid (18) on a clear sheet (20) that is then placed over the marked target so that a center (22) of the grid is located at the target center in order to permit determination of the horizontal and vertical deviation of the shot cluster center (36) from the target center, in order to permit necessary gun sight adjustment for proper aiming.

Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a kit and method for sighting a gun in order to permit adjustment of an associated gun sight for proper gun aiming during use.

2. Background Art

Gun sighting and any necessary adjustment are conventionally performed by firing rounds of the gun at a preprinted target that may be either a graph and/or concentric circular scoring rings such as disclosed by United States patents: U.S. Pat. No. 197,397 O'Neil; U.S. Pat. No. 3,118,674 Curren; U.S. Pat. No. 4,244,586 Gorrow and U.S. Pat. No. 6,213,470 Miller; and by U.S. patent application Publication US 2005/0268520 Ugolini et al. For gun aiming in this conventional manner, one must necessarily have a type of preprinted target when the aiming is to be performed which may result in a convenience interruption in addition to the cost involved.

SUMMARY OF THE INVENTION

An object of the present invention is to provide an improved gun sighting kit.

In carrying out the above object, the gun sighting kit of the invention includes a light transmitting sheet supported concentric circular graph having a center. A gun is aimed at a target which needs only a center target location such that a plurality of rounds establish a cluster of shots on the target. The concentric circular graph is placed over the target shot cluster such that the graph center determines a center of the shot cluster. A light transmitting sheet supported square grid of the gun sighting kit has a center and is then placed over the cluster of shots on the target to determine the horizontal and vertical deviation of the shot cluster center from the target center location to determine any necessary adjustment of the gun sight for proper gun aiming.

In the preferred construction of the gun sighting kit, separate light transmitting sheets respectively support the concentric circular graph and the square grid and both the concentric circular graph and the square grid are each supported on a clear light transmitting sheet. Furthermore, the concentric circular graph has a hole through the light transmitting sheet to permit marking of the shot cluster center on the target.

Another object of the present invention is to provide an improved method for sighting a gun.

In carrying out the above object, the improved method for sighting a gun in accordance with the invention is performed by firing a plurality of rounds at a target, which need only have a center target location, to establish a cluster of shots. A light transmitting sheet supported concentric circular graph having a center is placed over the cluster of shots and positioned with respect to the cluster of shots so its center establishes a shot cluster center. A light transmitting sheet supported square grid is then placed over shot cluster to determine the horizontal and vertical deviation of the shot cluster center from the center target location to thereby determine any necessary adjustment of the gun sight for proper aiming.

In the preferred practice of the gun sighting method, the concentric circular graph and the square grid are supported on separate light transmitting sheets and separately placed over the target from each other, and both the concentric circular graph and the square grid are each supported on a clear light transmitting sheet. Also, the concentric circular graph is supported on a light transmitting sheet having a hole through which the shot cluster center is marked on the target. Furthermore, any abnormal shots are ignored upon establishing the shot cluster center by the concentric circular graph.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a view illustrating a gun sighting kit that is constructed in accordance with the invention to perform the gun sighting method of the invention.

FIG. 2 is a view illustrating a target having a center location at which a cluster of shots are fired during the gun sighting.

FIG. 3 is a view illustrating the manner in which a light transmitting sheet having a concentric circular graph is placed over the shot cluster to establish a shot cluster center that is then marked on the target.

FIG. 4 is a view illustrating the manner in which a square grid on a light transmitting sheet is placed over the shot cluster to determine the horizontal and vertical deviation of the shot cluster center from the target center location in order to permit any necessary adjustment of the gun sight for proper gun aiming.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIG. 1 of the drawings, a gun sighting kit constructed in accordance with the present invention is collectively indicated by 8 and is utilized to perform a gun sighting method in accordance with the invention as is hereinafter more fully described. Both the gun sighting kit and the method for gun sighting will be described in an integrated manner to facilitate an understanding of all aspects of the invention.

As illustrated in FIG. 1, the gun sighting kit 8 includes a concentric circular graph 10 on a light transmitting sheet 12 that may be translucent but is preferably clear. The concentric circular graph 10 includes a plurality of concentric circles 14 and has a center 16 about which the circles are concentrically located. This circle center 16 has a hole 16′ for permitting marking as is hereinafter more fully described.

With continuing reference to FIG. 1, the gun sighting kit 10 also includes a square grid 18 supported on a light transmitting sheet 20 that may be translucent but is preferably clear. The square grid 18 has a center 22 and includes uniformly spaced horizontal and vertical graph lines 24 and 26, respectively, that are also used in the gun sighting as described below.

As illustrated in FIG. 2, a target 28 need only have a center location 30 which can easily be marked on any piece of paper, cardboard etc. so that the aiming can be performed without any preprinted target as has been previously required. The gun to be sighted is then aimed at the target center location 30 and a number of rounds are fired to provide a shot cluster 32 which has shots 34, five as shown, with four adjacent each other and one apparently errant shot which can result from improper aiming, wind, etc.

As illustrated in FIG. 3, the clear sheet 12 is then placed over the target 28 so its concentric circular graph 10 is positioned to have the smallest maximum circle that generally encompasses the shot cluster 32 while ignoring the one errant shot 34. This placement positions the graph center 16 at a shot cluster center that can then be marked through the sheet hole 16′ to provide the shot cluster center mark 36 as shown in FIG. 4.

With reference to FIG. 4, the concentric circle sheet 10 is removed and the clear sheet 20 is placed over the marked target 28 so the center 22 of its square grid graph 18 is located at the target center location 30 and positioned with the horizontal and vertical grid lines 24 and 26 generally horizontal and vertical in order to determine the necessary horizontal and vertical spacing of the marked shot cluster center 36 from the target center location 30.

After determining the shot cluster deviation, the gun can be adjusted horizontally and/or vertically as necessary and the sighting process can then be repeated once or more as necessary to insure that the gun is properly sighted.

While the preferred embodiment and practice of the invention have been illustrated and described, it is not intended that this embodiment and preferred practice illustrates and describes all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
