Abstract: The in-floor, flush poke-through wiring fitting may be installed in the floor of a structure to enable the activation of power, communication, and/or data services at the fitting location. The poke-through fitting includes an interference shielding barrier to prevent E.M. and R.F. interference with the signal services. The poke-through fitting also includes pre-shaped fire-retarding materials, which are encapsulated to prevent degradation and damage. The poke-through fitting accommodates RJ-45 Category 5 signal jacks such that the faces of the jacks (that is, the faces that may receive selectively, RJ-45 Category 5 connectors) are mounted substantially flush with an upper outwardly facing surface of the fitting.

Abstract: An insert for a poke-through fitting, including a plurality of sealing elements adapted to absorb heat, expand, and flow into openings under pressure, and a plurality of insulating elements adapted to absorb heat, cure, cross-link, emit water, and dissipate heat, upon activation by heat and flame from a fire. The sealing and insulating elements are adapted to enable the fire rating of the floor in which the poke-through fitting is installed to be substantially the same with or without the hole and fitting therein, to enable the hole in the floor to be smaller to reduce the hazard of transmission of heat and flame from a fire therethrough, and to enable the capacity for passing wires to be greater in the smaller hole for increased wire capacity.

Abstract: A poke-through fitting, adapted to feed a cable or cables therethrough to a piece of furniture, including a raceway extending through the fitting, and a top portion which includes a medial portion including a plurality of sides each adapted to normally close the fitting, and to enable an opening to be formed therein to enable egress of the cable or cables, adapted to enable the volume of the cable or cables passing therethrough to be substantially greater than the volume of a cable or cables adapted to pass through a standard furniture feed poke-through fitting.The fitting is further adapted to be fire rated, including sealing elements, insulating elements, and radiating elements adapted to enable the fire-rating of the fire-rated floor to be substantially the same with or without the hole and fitting therein.

Abstract: An automatic electric cable passage closure and sealing device, for positioning in an opening in a structure such as a floor or wall, etc., for passing or connecting a cable or cables and cable conduits therethrough, the device automatically expanding and sealing itself and the cables and cable conduits in the structural opening on occurrence of excess heat or fire. The device comprises a hollow conducting casing to be positioned in a cable or conduit passage in the structure, said casing having novel means effectuating automatic movement and expansion of intumescing, fire retarding, means on occurrence of fire or highly elevated temperatures, said intumescing means pressing through the cables insulation and onto the conductor wires interiorly of the cables.

Abstract: A through-floor electrical outlet fitting, for insertion into structural openings of minimum diameter. The device has means for interlocking with and conforming to such openings, and to those of a wide range of thicknesses, for locking the device in the opening. Raceway means in the device separate passage therethrough and transfer of electrical service cables for at least two different electrical functions or services, such as high and low voltage insulated cables. The device has intumescent means thereon, encircling the cable raceways to conform the length thereof to varying depths of structural openings, as fire rated insulating barriers, so disposed that there is no need for a multiplicity of devices or field adjustments for varying depths of structural openings. The device and above-floor service head portions are capable of accepting maximum size low voltage communication cables, through the use of a radiator separately mounted in the service head, to allow dissipation of heat to a non-sensitive area.

Abstract: A cable module device wherein a grommet plate closes the upper end of the module and, in the absence of high heat, seals and protects the module where, for example, a fire, located away from the module, results in cold smoke and water moving onto the module as from a sprinkler, fire hose, broken pipes, etc. on floor above or same floor as the module. The module is further provided with normally inert heat-sensitive plates which when triggered by a flame expand, to form a barrier in the module against passage therethrough of such excessive heat and flames.

Abstract: A trimless carpet base insert device, further provided with novel positioning and assembly features, enabling assembly and use thereof to be made in situ, by initially interlocking end members of the insert device with apertured portions of the cable raceway, thereby providing registration guide means for receiving and registering body portions of the insert device with said raceways, complementary interlocking means being provided on the body portion and end members. Thus the insert device body parts may be readily and compactly packaged and shipped and furnished to contractors and others in parts for ready assembly and installation in original building construction procedure or for subsequently positioning them as modules or units in openings formed in floors or other structural members.

Abstract: A novel conduit device including oppositely opening conduit sections of triangular outline, formed complementarily with and engaging and grommeting axially offset apertures in the side walls of parallel raceways, for separate passage through the raceways and the conduit device of elongated different purpose and forms of devices, such as telephone and power cables and wires, avoiding danger of crossing such wires, and assuring their passage in safety through the device and to the related apparatus.

Abstract: A trimless flush floor fitting for positioning at an opening in a floor or other structural member, at a level line of said structural member, the fitting comprising a leveling frame member and linkage members complementarily adjustably connecting the frame member with a bracket in said floor opening, whereby, on actuation of the linkage means, said leaving frame may be adjustably moved to conform to the level line of the structural surface, without the necessity of using complex and special trim accessories. No trim shows on the carpeting or other floor covering material, the latter being used without pieces being removed therefrom (as in prior practices). Architecturally there is only a minimum of clutter on the carpet surface, only the cables, when coming through the device being visible; when the device is not in use, it is completely invisible and concealed by the carpet, which is back in place.

Abstract: This invention relates to a device for forming a pre-set void in a floor, wall or other structural member, to thereby define an essentially integral spatial void or closure therein, which maintains the UL fire rating of the floor or other structural member in which it is positioned, and which may be readily removed, when desired, to define the void, without use of special tools or procedures. The device is useful for defining modular or other openings to receive, for example, insert devices, through which cables, such as power and telephone lines, may be passed from a source, for connection with fixtures, phones and other devices. The device is adapted to be secured to forms, for example so that a material such as cement or other floor, wall or other structural forming materials may be positioned or poured thereon and therearound; the device in such cases may form a preset-sealed part of the structural member, readily available for opening when desired.

Abstract: This invention relates to an apparatus for sealing a passage through a concrete floor and about a conductor, such as an insert device for cables adapted to be positioned in structural openings, such as, for example in holes drilled into or formed in floors and other planar surfaces of structures such as buildings, to facilitate connection of power lines, cables and wires from a source into a cable receiving junction box at the underside of the floor and through the insert device and thence to a service head at the upper face of the floor, for connection of various accessory devices thereto, a fire retardant hollow member, comprised of water-containing alkali metal silicate, being provided to seal the device in the floor opening and to seal the cables therein, automatically foaming to effectuate the sealing action described, on occurrence of fire or excessive temperatures, to effectively so seal the assembly.
