Abstract
Abstract A transparent plexiglass light conductor tube has a flashlight connected to one end with a lens and mirror on an opposite end being insertable in a gun bore so that light from the flashlight travels along the rod and is reflected by the mirror to the dispersing lens which radiates the light outwardly to illuminate the surrounding bore area. The transparent light conductor rod has an offset outer end portion to which the flashlight is connected so that the user has a clear view down the bore along the surface of the rod for inspecting the bore as the rod is moved axially along the length of the bore.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
216 words
An illuminating device for permitting the illumination and inspection of a gun bore or the like having a bore diameter, said illuminating device comprising: a light source; a transparent light conductor rod of less diameter than said bore diameter and having first and second ends and dimensioned and shaped to permit insertion of said second end into said bore; connector means holding said first end of said transparent light conductor rod in facing relation to said light source for receiving light from said light source to be transmitted along the length of said transparent light conductor rod to said second end thereof; a light reflecting mirror dimensioned to be insertable into said bore and positioned in facing relation to said second end of said transparent light conductor rod to receive and deflect light therefrom; and dispersing lens means for receiving light reflected from said light reflecting mirror and directing such light outwardly to illuminate the adjacent bore surface surrounding said dispersing lens, said dispersing lens being of greater diameter than the diameter of said light conductor rod and having a first face fixed to the second end of said light conductor rod and a second face spaced away from said second end of said light conductor rod with said mirror being positioned on said second face.
Claim 2
Dependent Claim
216 words
An illuminating device for permitting the illumination and inspection of a gun bore or the like having a bore diameter, said illuminating device comprising: a light source; a transparent light conductor rod of less diameter than said bore diameter and having first and second ends and dimensioned and shaped to permit insertion of said second end into said bore; connector means holding said first end of said transparent light conductor rod in facing relation to said light source for receiving light from said light source to be transmitted along the length of said transparent light conductor rod to said second end thereof; a light reflecting mirror dimensioned to be insertable into said bore and positioned in facing relation to said second end of said transparent light conductor rod to receive and deflect light therefrom; and dispersing lens means for receiving light reflected from said light reflecting mirror and directing such light outwardly to illuminate the adjacent bore surface surrounding said dispersing lens, said dispersing lens being of greater diameter than the diameter of said light conductor rod and having a first face fixed to the second end of said light conductor rod and a second face spaced away from said second end of said light conductor rod with said mirror being positioned on said second face.
Claim 3
Dependent Claim
54 words
The illuminating device of claim 1 wherien said transparent light conductor rod includes inner and outer linear rod portions oriented at an obtuse angle with respect to each other with the inner linear rod portion being positionable in said bore and the outer linear rod portion being positioned outwardly thereof in an offset manner.
Claim 4
Dependent Claim
15 words
The illuminating device of claim 2 wherein said light conductor rod is formed of plexiglass.
Claim 5
Dependent Claim
64 words
The illuminating device of claim 1 wherein said transparent light conductor rod includes inner and outer linear rod portions oriented at an obtuse angle with respect to each other with the inner linear rod portion being positionable in said bore and the outer linear rod portion being positioned outwardly thereof in an offset manner and wherein said light source comprises a battery powered flashlight.
Claim 6
Dependent Claim
40 words
The illuminating device of claim 4 wherein said connector means comprises nipple means having a first end matingly fitting over the first end of said transparent light conductor rod and a second end matingly fitting over said battery powered flashlight.
