Gun sighting and ranging mechanism

Claim 2

In a sighting and ranging mechanism for a gun, the combination comprising: a sight scope mountable on a barrel of a gun, said scope having optical means defining an optical axis forming a substantially fixed reference line of sight, an image plane transverse to said optical axis onto which an image of the target is formed, and a point sight adapted to be visually aligned with any part of said image for sighting the gun on the target; and image moving means for substantially simultaneously determining the range of the target and vertically displacing the target image from said reference line of sight an amount sufficieNt to compensate for the range of the target and the trajectory of the bullet.

Claim 3

The invention according to claim 1 wherein said image moving means comprises an image displacing means interposed between said image plane and said point sight.

Claim 4

The invention according to claim 2 wherein said image displacing means comprises a pivotally mounted elevation plate.

Claim 5

In a sighting and ranging mechanism for a gun having a primary objective lens defining an optical axis, an image plane transverse to said optical axis and a point sight which when aligned with a reference point on said image plane at said optical axis forms a substantially fixed reference line of sight along which a target is sighted, the combination comprising: means for forming a pair of independent images of a target on said image plane; and image moving means for substantially simultaneously moving said pair of images into register and vertically displacing said registered images from said reference line of sight a predetermined amount to compensate for the range of the target and the trajectory of a bullet.

Claim 6

In a sighting and ranging mechanism for a gun having a primary objective lens defining an optical axis, an image plane transverse to said optical axis and a point sight which when aligned with a reference point on said image plane at said optical axis forms a substantially fixed reference line of sight along which a target is sighted, the combination comprising: means for forming a pair of independent images of a target on said image plane; and image moving means for substantially simultaneously moving said pair of images into register and vertically displacing said registered images from said reference line of sight a predetermined amount to compensate for the range of the target and the trajectory of a bullet.

Claim 7

The invention according to claim 4 wherein said image moving means comprises an image displacement means interposed between said image plane and said point sight for displacing the registered images.

Claim 8

The invention according to claim 5 wherein said image displacement means comprises a pivotally mounted elevation plate.

Claim 9

In a biscope sighting and ranging mechanism for a gun, the combination comprising: sighting means mountable on to a barrel of the gun and having optical means having a primary optical axis, an image plane transverse to said optical axis and a point sight which when aligned with a reference point on said image plane at said optical axis forms a substantially fixed reference line of sight; first optical means for forming a first image of a target on said image plane; second optical means optically coupled to said first optical means for forming a second image of the target independent of said first image on said image plane; and image moving means coupling said first and second optical means for substantially simultaneously moving said first and second images on said image plane into register and vertically displacing said registered images from said reference line of sight an amount dependent upon the distance to the target and the trajectory of the bullet such that when said point sight is sighted on a spot on said registered images, the gun barrel is pointed at a place on the target above said spot on said registered images so that a bullet fired from the gun will strike a corresponding spot on the target.

Claim 10

In a biscope sighting and ranging mechanism for a gun, the combination comprising: sighting means mountable on to a barrel of the gun and having optical means having a primary optical axis, an image plane transverse to said optical axis and a point sight which when aligned with a reference point on said image plane at said optical axis forms a substantially fixed reference line of sight; first optical means for forming a first image of a target on said image plane; second optical means optically coupled to said first optical means for forming a second image of the target independent of said first image on said image plane; and image moving means coupling said first and second optical means for substantially simultaneously moving said first and second images on said image plane into register and vertically displacing said registered images from said reference line of sight an amount dependent upon the distance to the target and the trajectory of the bullet such that when said point sight is sighted on a spot on said registered images, the gun barrel is pointed at a place on the target above said spot on said registered images so that a bullet fired from the gun will strike a corresponding spot on the target.

Claim 11

The invention according to claim 7 wherein said second optical means has an image deflecting element optically connecting said second optical means to said first optical means.

Claim 12

The invention according to claim 7 wherein said second optical means has an image deflecting element comprising a parallelogram shaped prism optically connecting said second optical means to said first optical means.

Claim 13

The invention according to claim 7 wherein said second optical means has an image deflecting element comprising a parallelogram shaped glass prism optically connecting said second optical means to said first optical means, said image plane being formed in said prism along the optical axis of said first optical means.

Claim 14

The invention according to claim 7 wherein said second optical means has an image deflecting element optically connecting said second optical means to said first optical means, and a third portion extending transversely from said second optical means for collecting light from the subject and introducing the light into said second optical means.

Claim 15

The invention according to claim 11 wherein said third portion is pivotally mounted on said second optical means.

Claim 16

The invention according to claim 7 in which said image moving means comprises at least one image deflecting plate responsive to said image moving meaNs for displacing said images from said reference line of sight.
