Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
121 words
An explosion-proof junction box for electrical connection junctures, or the like, including a cap portion and a body portion, said cap and body portions having a resilient, moisture resistant polymeric coating, said coating extending beyond the respective peripheries of said cap and said body portions whereby respective resilient flanges are formed thereon, said cap and body portions including threaded portions for threadably advancing said cap portion into said body portion whereby said resilient flange portions come into sealing contact to provide an effective one-way vapor seal for said junction box to prevent the flow of corrosive vapors into the threaded portions of said cap and body portions and permit the outflow of gas from said junction box through said threaded portions.
Claim 2
Dependent Claim
121 words
An explosion-proof junction box for electrical connection junctures, or the like, including a cap portion and a body portion, said cap and body portions having a resilient, moisture resistant polymeric coating, said coating extending beyond the respective peripheries of said cap and said body portions whereby respective resilient flanges are formed thereon, said cap and body portions including threaded portions for threadably advancing said cap portion into said body portion whereby said resilient flange portions come into sealing contact to provide an effective one-way vapor seal for said junction box to prevent the flow of corrosive vapors into the threaded portions of said cap and body portions and permit the outflow of gas from said junction box through said threaded portions.
Claim 3
Dependent Claim
38 words
The explosion-proof junction box as set forth in claim 1 wherein said respective resilient flange portions comprise a flange portion extending generally downwardly of said cap portion and a flange portion extending generally upwardly of said body portion.
Claim 4
Dependent Claim
19 words
The explosion-proof junction box as set forth in claim 2 wherein said polymeric coating comprises a polyvinylchloride film coating.
Claim 5
Dependent Claim
39 words
The explosion-proof junction box as set forth in claim 3 wherein said threaded portions comprise an external threaded portion extending downwardly of said cap portion and formed integrally thereof, and an internal threaded portion formed integrally of said portion.
Claim 6
Dependent Claim
27 words
The explosion-proof junction box as set forth in claim 4 wherein said external threaded portion and said internal threaded portion include respective helical threads having differing dimensions.
Claim 7
Dependent Claim
63 words
The explosion-proof junction box as set forth in claim 5 wherein said cap and body portions include respective cap flange and body flange portions, and wherein said cap flange and body flange portions may abut, each of said cap flange and body flange portions having a ground surface for providing a passageway through which gases may pass between said ground and abutting surfaces.
Claim 8
Dependent Claim
51 words
The explosion-proof junction box as set forth in claim 1 wherein said body portion includes one or more pipe coupling members extending therefrom for receiving a wire bearing conduit, and wherein said coating extends beyond each of said coupling members for providing a moisture resistant sleeve for sealably engaging said conduit.
