Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 90 words
A new- construction metal electrical box of the type originally having electrical device mounting ears, said box including cable clamps at the rear thereof secured to said box by cable clamp screws, one of said mounting ears having been knocked off said box, said box including a replacement for said mounting ear comprising a metal bracket clipped onto the wall of said box on each side of the former location of said knocked-off ear, and secured to the rear of said box by one of the cable clamp screws thereof.
Claim 2
Dependent Claim 90 words
A new- construction metal electrical box of the type originally having electrical device mounting ears, said box including cable clamps at the rear thereof secured to said box by cable clamp screws, one of said mounting ears having been knocked off said box, said box including a replacement for said mounting ear comprising a metal bracket clipped onto the wall of said box on each side of the former location of said knocked-off ear, and secured to the rear of said box by one of the cable clamp screws thereof.
Claim 3
Dependent Claim 84 words
The electrical box of claim 1 wherein said metal bracket comprises a main body portion with a 90 degree bent-over tab at the center of one end thereof and a 90 degree bent-over replacement mounting ear at the center of the other end of said main body, said tab and said mounting ear being bent-over in opposite directions, and wherein said bracket is clipped to said wall of said box by a pair of bent-back sections on each side of said replacement mounting ear.
Claim 4
Dependent Claim 27 words
The electrical box of claim 2 wherein the distance between said replacement mounting ear and said tab is approximately equal to the inside depth of said box.
Claim 5
Dependent Claim 191 words
A metal bracket adapted to be applied to a metallic electrical box of the new-construction type, from which one of the electrical device mounting ears is missing, comprising, a main body portion generally in the shape of a triangle, with a 90 degree bent-over tab at the apex of said triangle, a hole in said tab, a replacement electrical device mounting ear at the center of the base of said triangle, said ear being bent-over 90 degrees in the opposite direction from said tab at the apex of said triangle, and a pair of bent-back portions on each side of said replacement ear, said bent-back portions being adapted to clip over the edge of said electrical box on each side of said missing mounting ear to aid in securing said metal bracket thereto, and wherein said hole in said tab at the apex of said triangle is large enough to accommodate the outside diameter of the screw used to hold down the cable clamp of said electrical box, and in which said electrical device mounting ear has a threaded hole therein used for securing an electrical device to said electrical box.
Claim 6
Dependent Claim 191 words
A metal bracket adapted to be applied to a metallic electrical box of the new-construction type, from which one of the electrical device mounting ears is missing, comprising, a main body portion generally in the shape of a triangle, with a 90 degree bent-over tab at the apex of said triangle, a hole in said tab, a replacement electrical device mounting ear at the center of the base of said triangle, said ear being bent-over 90 degrees in the opposite direction from said tab at the apex of said triangle, and a pair of bent-back portions on each side of said replacement ear, said bent-back portions being adapted to clip over the edge of said electrical box on each side of said missing mounting ear to aid in securing said metal bracket thereto, and wherein said hole in said tab at the apex of said triangle is large enough to accommodate the outside diameter of the screw used to hold down the cable clamp of said electrical box, and in which said electrical device mounting ear has a threaded hole therein used for securing an electrical device to said electrical box.
Claim 7
Dependent Claim 35 words
The metal bracket of claim 4 wherein the distance from the tab at the apex of said triangle to the electrical device mounting ear is approximately equal to the inside depth of said electrical box.
Claim 8
Dependent Claim 131 words
A metal bracket comprising a flat main body portion with a 90 degree mounting tab at one end thereof and a replacement electrical device mounting ear with a hole therein at the center of the other end thereof, and a pair of bent-back sections on each side of said mounting ear, the distance between said mounting tab and said mounting ear being approximately equal to the inside depth of an installed new construction electrical box from which one of the mounting ears is missing, whereby said bracket may be quickly and easily applied to said installed electrical box to provide a replacement for said missing electrical device mounting ear, and wherein said mounting tab and said mounting ear are bent 90 degrees from said main body portion, but in opposite directions.
Claim 9
Dependent Claim 131 words
A metal bracket comprising a flat main body portion with a 90 degree mounting tab at one end thereof and a replacement electrical device mounting ear with a hole therein at the center of the other end thereof, and a pair of bent-back sections on each side of said mounting ear, the distance between said mounting tab and said mounting ear being approximately equal to the inside depth of an installed new construction electrical box from which one of the mounting ears is missing, whereby said bracket may be quickly and easily applied to said installed electrical box to provide a replacement for said missing electrical device mounting ear, and wherein said mounting tab and said mounting ear are bent 90 degrees from said main body portion, but in opposite directions.
