Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
94 words
A waterproof signal light which comprises an electric light bulb having a filament enclosed by a transparent member and connected at its opposite extremities to two terminals in a base supporting said transparent member, first and second conductive leads connected to and extending from said terminals, and means completely and sealingly encapsulating said bulb and portions of said leads where connected to said bulb; said first conductive lead being formed by relatively massive and heat conductive material in the form of a rigid bracket adapted to mount the entire unit from an exterior support.
Claim 2
Dependent Claim
94 words
A waterproof signal light which comprises an electric light bulb having a filament enclosed by a transparent member and connected at its opposite extremities to two terminals in a base supporting said transparent member, first and second conductive leads connected to and extending from said terminals, and means completely and sealingly encapsulating said bulb and portions of said leads where connected to said bulb; said first conductive lead being formed by relatively massive and heat conductive material in the form of a rigid bracket adapted to mount the entire unit from an exterior support.
Claim 3
Dependent Claim
45 words
A waterproof signal light according to claim 1 wherein one of said light bulb terminals constitutes a cylindrical conductor and said first conductive lead is connected to said cylindrical conductor over an extensive area to provide an effective and substantial current and heat transfer therebetween.
Claim 4
Dependent Claim
31 words
A waterproof signal light according to claim 1 wherein said encapsulating means constitutes relatively rigid material encompassing a substantial part of said first conductive lead to provide a fixed support therefor.
Claim 5
Dependent Claim
17 words
A waterproof signal light according to claim 1 wherein said encapsulating means is formed by translucent material.
Claim 6
Dependent Claim
21 words
A waterproof signal light according to claim 4 which comprises a reflective backing on one portion of said translucent encapsulating means.
Claim 7
Dependent Claim
38 words
A waterproof signal light according to claim 1 which comprises a rigid grounded electric member mounting said first conductive lead so as to electrically ground, physically support, and provide heat transfer from said bulb and first conductive lead.
