  "title": "Lighting fixture",
  "abstract": "The lighting fixture is adapted to be secured to the outer periphery of a generally vertically disposed column. The fixture is comprised of at least two housing sections which are coupled together with each housing section having a recess on its inner periphery for embracing a portion of the vertically disposed column. Each housing section has a source of illumination for projecting light upwardly through a transparent portion of the top wall of each housing section.",
  "claims": [
    "1. A lighting fixture adapted to be secured to a vertically disposed column intermediate the ends thereof comprising a housing divided into at least two sections, each housing section having an inner periphery and an outer periphery, the inner periphery on each housing section having a recess for receiving there within a portion of the periphery of a generally vertically disposed column or pole, each housing section having there within at least one source of illumination, each housing section having a top wall with a transparent portion through which illumination may be projected generally upwardly from its associated light source, each transparent portion being removably supported by said top wall to facilitate relamping of its associated light source without interfering with the mounting of the housing section on the column or pole, coupling means joining said sections together at juxtaposed walls on said section, said juxtaposed wall and said coupling means being disposed between the inner and outer peripheries of said sections, and means for securing said sections to a generally vertically disposed column or pole in a manner so that the inner periphery of the housing sections embrace the outer periphery of a column or pole, said securing means supporting said housing sections at a location between the inner and outer peripheries of said sections.",
    "2. A lighting fixture in accordance with claim 1 including means defining a hollow wireway extending between the juxtaposed walls of said housing sections.",
    "3. A lighting fixture in accordance with claim 1 wherein each leg of each clip means extends downwardly into the space between a pair of juxtaposed portions on said securing means.",
    "4. The lighting fixture in accordance with claim 1 wherein the juxtaposed walls which are joined together by said coupling means are vertically disposed and fixedly connected to a bottom wall of its associated housing section, each housing section having a top wall fixedly secured to an outer peripheral wall of its associated section, whereby each housing section is defined by two sets of mating walls which are movable with respect to each other, each set of mating walls including a horizontally disposed wall and a vertical wall, and fastener means for removably securing the horizontal walls to an adjacent vertical wall of its set.",
    "5. The lighting fixture in accordance with claim 1 wherein each housing section is provided with a clip means adjacent the upper end thereof, each clip means having a downwardly extending leg to facilitate support of the associated housing section on said securing means before said housing sections are coupled together by said coupling means.",
    "6. The lighting fixture in accordance with claim 1 wherein said securing means includes two sets of parallel spaced apart plates which support said housing sections, each of the plates being vertically disposed, the sets being approximately 180° apart and extending outwardly away from a centrally disposed clamp means.",
    "7. The lighting fixture in accordance with claim 6 wherein said clamp means includes a plurality of clamp sections bolted together, each clamp section having an inner peripheral surface contoured to facilitate clamping to circular and non-circular surfaces of a generally vertically disposed column.",
    "8. The lighting fixture in accordance with claim 6 wherein the plates of each set have aligned holes, said coupling means joining said sections together including a discrete fastener extending through each of the aligned holes in said sets of plates.",
    "9. The lighting fixture in accordance with claim 1 wherein said housing is annular, each housing section having a plurality of sources of illumination, the sources of illumination on said housing being equally spaced.",
    "10. The lighting fixture in accordance with claim 1 wherein said sources of illumination are arranged for directing illumination upwardly and outwardly away from the axis of said recesses.",
    "11. A lighting fixture comprising a housing divided into at least two sections, each housing section having an inner periphery and an outer periphery, the outer periphery on each housing section having a recess for receiving therein a portion of the periphery of a generally vertically disposed column, each housing section having therewithin at least one source of illumination, each housing section having a horizontally disposed wall with a transparent portion through which illumination may be projected from its associated source of illumination, coupling means joining said sections together, means for securing said sections to a column in a manner so that the inner periphery of the housing sections embrace the outer periphery of a column, said securing means including a plurality of components bolted together for clamping to the outer periphery of a column, means on each section at a location between the inner and outer peripheries of each section for coupling each section to said securing means so that said securing means supports each housing section.",
    "12. A lighting fixture in accordance with claim 11 wherein each housing section is comprised of two housing portions, each housing portion having a horizontally disposed wall connected to a vertically disposed wall, and fastener means removably securing each horizontal wall to an associated vertical wall of its housing portion.",
    "13. A lighting fixture in accordance with claim 11 wherein said coupling means includes a member extending through said securing means.",
    "14. A lighting fixture in accordance with claim 13 wherein said coupling means is hollow so that it may be used as a wireway."

  "description_excerpt": "It is known to attach a lighting fixture to a generally vertically disposed column at a location intermediate the ends of the column. See U.S. Pat. Nos. 2,456,179 and 3,777,138. In U.S. Pat. No. 2,456,179, the fixture is attached to the column by means of a limit stop ring welded to the outer periphery of the column. Attachment of a fixture to a column in that manner is frequently impractical, too expense or undesirable. In U.S. Pat. No. 3,777,138, the fixture is attached to the column by way of a set screw which inherently limits the weight and type of fixture which can be attached in that manner.\n\nThere is a need for a lighting fixture which is readily attachable to the outer periphery of new or existing vertical columns, with the fixture being arranged to direct illumination generally upwardly.\n\nThe present invention is directed to a lighting fixture adapted to be secured to a generally vertically disposed column. The fixture includes a housing divided into at least two sections. Each housing section has an inner periphery and an outer periphery. The inner periphery on each housing section has a recess for receiving therein a portion of the periphery of the generally vertically disposed column. Each housing section has therewithin at least one source of illumination. The top wall of each housing section is provided with a transparent portion through which illumination may project generally upwardly from its associated light source. Each of said transparent portions is removably supported to facilitate relamping its associated light source.",
