Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
The combination comprising A. an electrical unit provided with an elongated metal mounting yoke having an opening proximate one end thereof, B. means for attaching said unit to a metal flush box and simultaneously making low resistance electrical contact between said yoke and box including 1. a clip extending lengthwise of said yoke across and through said opening and having one end portion hooked about the terminal portion of said yoke, 2. means on the portion of said clip extending across and through said opening hooked about the edge of said opening remote from the terminal portion of said yoke, and 3. a screw projected through the opening in said yoke and a registering opening in said clip, the portion of said clip hooked about the edge of said opening remote from the terminal portion of said yoke being flexed by said screw, and being operative thereby to hold said screw fast against the edge of said opening proximate the terminal portion of said yoke.
Claim 2
Dependent Claim
165 words
The combination comprising A. an electrical unit provided with an elongated metal mounting yoke having an opening proximate one end thereof, B. means for attaching said unit to a metal flush box and simultaneously making low resistance electrical contact between said yoke and box including 1. a clip extending lengthwise of said yoke across and through said opening and having one end portion hooked about the terminal portion of said yoke, 2. means on the portion of said clip extending across and through said opening hooked about the edge of said opening remote from the terminal portion of said yoke, and 3. a screw projected through the opening in said yoke and a registering opening in said clip, the portion of said clip hooked about the edge of said opening remote from the terminal portion of said yoke being flexed by said screw, and being operative thereby to hold said screw fast against the edge of said opening proximate the terminal portion of said yoke.
Claim 3
Dependent Claim
29 words
means on the portion of said clip extending across and through said opening hooked about the edge of said opening remote from the terminal portion of said yoke, and
Claim 4
Dependent Claim
29 words
means on the portion of said clip extending across and through said opening hooked about the edge of said opening remote from the terminal portion of said yoke, and
Claim 5
Dependent Claim
23 words
The combination according to claim 1 wherein the clip consists of a strip of light gauge sheet metal having a low electrical resistance.
Claim 6
Dependent Claim
44 words
The combination according to claim 2 wherein the means hooked about the edge of the opening remote from the terminal portion of the yoke is a tab struck out of the portion of the strip of sheet metal extending across and through said opening.
Claim 7
Dependent Claim
63 words
a screw projected through the opening in said yoke and a registering opening in said clip, the portion of said clip hooked about the edge of said opening remote from the terminal portion of said yoke being flexed by said screw, and being operative thereby to hold said screw fast against the edge of said opening proximate the terminal portion of said yoke.
Claim 8
Dependent Claim
63 words
a screw projected through the opening in said yoke and a registering opening in said clip, the portion of said clip hooked about the edge of said opening remote from the terminal portion of said yoke being flexed by said screw, and being operative thereby to hold said screw fast against the edge of said opening proximate the terminal portion of said yoke.
Claim 9
Dependent Claim
58 words
The combination according to claim 3 wherein the screw is tapered under head and the shank thereof extends through the opening in the strip of sheet metal resulting from said tab being stRuck therefrom, and said tab extends back up through the opening in the yoke and outwardly from said screw in line contact with said tapered undersurface.
Claim 10
Dependent Claim
40 words
The combination according to claim 4 wherein the edge of the opening in the strip of sheet metal remote from the tab is at least as remote from said tab as the corresponding edge of the opening in the yoke.
