摘要： 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. Said wires are thereby automatically sealed in the casing, and in the structure, said intumescing means expanding in and around the casing, completely filling the casing and the floor or wall opening wherein the casing is positioned, automatically forming a unitary and continuous closure of the structure wherein the device is positioned, preventing passage of heat or flames therethrough.

摘要： 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.

摘要： 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.

摘要： 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. The cables on such occurrence, are thus sealed in the insert device in air-tight, spaced relation to each other; spread of fire and excess heat therethrough will be automatically prevented, and the fire protection rating of the floor wherein the insert device is so mounted and used will be substantially equivalent to the original rating of the floor.

摘要： 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. The insert further includes a retaining element, assisted by compressible sealing elements, adapted to enable the insert to be retained in the hole in the floor, and, upon the exertion of increased pulling force, to be held fast in the hole in the floor, to prevent the safety hazard of electrical shock and fire from exposed live ends of pulled-apart power wires.

摘要： 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.

摘要： 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.
