Abstract
Abstract The lighting fixture is adapted to be supported on a pole, or post top or the like and has a generally cylindrical body portion or hub portion from which extends laterally one or more arms. The arms carry the necessary lamp supporting means and wires thereto. The body portion in the preferred form has a downwardly opening tapered socket, preferably conical, which may be nested with and supported on a mating stud. There is a stop to limit the nesting of the body portion with a supporting stud and, preferably, each body portion has an upwardly extending stud with an external configuration which conforms to the internal configuration of the socket of a lighting fixture whereby the fixtures may be nested to supply more than one lighting fixture supported on a pole, post, or the like. The conical socket is, in each case, provided with one or more set screws. Three set screws permit free lateral as well as vertical adjustment of the unit. The conical socket may be telescoped with and joined to a cylindrical support such as a pole top as well as to the conical stud portion of an associated fixture unit. The studs are preferably hollow and conductors for the associated lamp or lamps and may be extended vertically through an opening in the top wall of the stud to enter a cooperating fixture unit. Hollow laterally extending lamp fixture supporting arms are extended from the body portions and communicate with the interior of the body portion.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
131 words
A lighting fixture adapted to be supported on a pole top or the like comprising a hollow generally cylindrical body portion with one or more hollow arms extending laterally from said body portion, lamp supporting means including electrical wires and terminals carried in said arm, said hollow body portion providing a downwardly opening conical socket by which said fixture may be nested with and supported on a mating conical stud, said socket having a stop to limit the nesting of the body portion with a supporting and mating stud, said hollow body portion having a conical stud extension at its upper end, the external configuration of which stud conforms to the internal configuration of the socket whereby the fixture may be nested with a supporting and mating stud of another fixture.
Claim 2
Dependent Claim
131 words
A lighting fixture adapted to be supported on a pole top or the like comprising a hollow generally cylindrical body portion with one or more hollow arms extending laterally from said body portion, lamp supporting means including electrical wires and terminals carried in said arm, said hollow body portion providing a downwardly opening conical socket by which said fixture may be nested with and supported on a mating conical stud, said socket having a stop to limit the nesting of the body portion with a supporting and mating stud, said hollow body portion having a conical stud extension at its upper end, the external configuration of which stud conforms to the internal configuration of the socket whereby the fixture may be nested with a supporting and mating stud of another fixture.
Claim 3
Dependent Claim
20 words

Claim 6
Dependent Claim
22 words
The lighting fixture of claim 3 wherein the arms are diametrically opposed to each other and formed integral with the body portion.
Claim 7
Dependent Claim
15 words
The lighting fixture of claim 1 wherein a diffuser is operatively associated with each arm.
Claim 8
Dependent Claim
23 words
The lighting fixture of claim 1 wherein the stud is hollow and is an axial extension of the socket of the body portion.
Claim 9
Dependent Claim

Claim 11
Dependent Claim
147 words
In a lighting fixture combination a first unit comprising a hollow cylindrical member having a body portion and an upwardly and inwardly tapered hollow stud portion, said first unit being adapted to be supported on a pole top, said stud portion having a horizontal top wall with an opening therethrough for an electric conductor and an annular shoulder at the junction of said body portion and said stud portion, a cooperating unit comprising a socket portion adapted to nest over said hollow stud portion of the first unit and seat on said annular shoulder, and having a hollow laterally extending arm adapted to support an electric light, said latter unit having a hollow laterally extending arm terminating in a lamp supporting portion said arm providing a duct for a conductor extending from the lamp supporting means through the opening in the top wall of the first unit.
Claim 12
Dependent Claim
147 words
In a lighting fixture combination a first unit comprising a hollow cylindrical member having a body portion and an upwardly and inwardly tapered hollow stud portion, said first unit being adapted to be supported on a pole top, said stud portion having a horizontal top wall with an opening therethrough for an electric conductor and an annular shoulder at the junction of said body portion and said stud portion, a cooperating unit comprising a socket portion adapted to nest over said hollow stud portion of the first unit and seat on said annular shoulder, and having a hollow laterally extending arm adapted to support an electric light, said latter unit having a hollow laterally extending arm terminating in a lamp supporting portion said arm providing a duct for a conductor extending from the lamp supporting means through the opening in the top wall of the first unit.
Claim 13
Dependent Claim
