Abstract
Abstract A light unit attachable to a swimming pool tank having sidewalls above the ground level and terminating in an upper rim, the light having a substantially U-shaped supporting member of which one leg extends from the rim of the tank downwardly along the inner surface of the sidewall thereof and has an electric light within a light shield supported by the lower end of said leg, while the opposite leg of the member is disposed along the outer surface of the sidewall of the pool tank and engages the same in opposition to the first-mentioned leg so as to stabilize the support of the light within the tank. Several embodiments of adjustable bracket means are included and the light is furnished with electric current by a conduit extending up the leg of the U-shaped member which extends along the inner surface of the tank, said conduit being connectable to a source of surrent, preferably low voltage, supplied either by a transformer or by rechargeable batteries.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
A light unit for a swimming pool tank having sidewalls above ground level terminating in an upper rim, said light unit comprising in combination, an elongated conduit member having a light shield on one end adapted to extend downwardly into said tank for a substantial distance adjacent the inner surface of the sidewall thereof, bracket means connected to the opposite end of said member and having a horizontal portion adapted to extend across the rim of said tank, clamping means comprising an elongated leg extending downward from and connected to said bracket means and having a clamping abutment adjustable thereon laterally relative to said leg for engagement with the outer surface of the sidewall of said tank substantially in opposition to the light shield on said elongated conduit member to clamp said member and light thereon to said sidewall within the interior of said tank, and an electric conduit connected at one end to and extending from said light shield along said elongated conduit member and connectable at the other end to a source of electric current.
Claim 2
Dependent Claim
177 words
A light unit for a swimming pool tank having sidewalls above ground level terminating in an upper rim, said light unit comprising in combination, an elongated conduit member having a light shield on one end adapted to extend downwardly into said tank for a substantial distance adjacent the inner surface of the sidewall thereof, bracket means connected to the opposite end of said member and having a horizontal portion adapted to extend across the rim of said tank, clamping means comprising an elongated leg extending downward from and connected to said bracket means and having a clamping abutment adjustable thereon laterally relative to said leg for engagement with the outer surface of the sidewall of said tank substantially in opposition to the light shield on said elongated conduit member to clamp said member and light thereon to said sidewall within the interior of said tank, and an electric conduit connected at one end to and extending from said light shield along said elongated conduit member and connectable at the other end to a source of electric current.
Claim 3
Dependent Claim
43 words
The light unit according to claim 1 in which said horizontal portion has a depending flange provided with a clamping screw extending through said depending flange for engagement with the upper rim of a swimming pool to clamp said horizontal portion directly thereto.
Claim 4
Dependent Claim
39 words

Claim 6
Dependent Claim
33 words
The light unit according to claim 4 in which said additional abutment means is adjustable toward and from said light shield to vary the angle thereof relative to the sidewall of the pool.
Claim 7
Dependent Claim
59 words
The light unit according to claim 1 further including a bracket adapted to be attached to the sidewall of a swimmIng pool against the inner surface thereof adjacent said light shield, and said light shield having a retaining member thereon connectable to said bracket to prevent lateral movement of said light shield relative to the sidewall of said pool.
Claim 8
Dependent Claim
33 words
The light unit according to claim 6 in which said retaining member has a downwardly extending tang and said bracket has an opening with a substantially vertical axis to slidable receive said tang.
