  • Patent number: 4323727
    Abstract: Cable strain relief and sealing apparatus comprising a sleeve formed of flexible and resilient material having a substantially cylindrical inner surface and a tapered outer surface. The sleeve may be tapered inwardly from the mid-portion thereof to both end portions thereof or, alternatively, may be provided with a taper in one direction only. A plurality of oppositely extending axial slots are formed in the sleeve so that, upon radial inward compression of the sleeve by a housing member or the like enclosing the sleeve, the internal surface of the sleeve will tightly grip a cable passing therethrough. A sealing bushing formed of flexible and resilient material may be provided at each tapered end of the sleeve, and may have a taper that is substantially the same as that of the sleeve.

  • Patent number: 4319724
    Abstract: A lightweight cable support ladder comprising siderail members, preferably made from a lightweight material, and rungs, also preferably made from a lightweight material. The rungs are friction fitted into continuous slots in the siderail members and may be welded for added rigidity. The basic ladder may be preassembled in standard lengths. Joining members, which allow either horizontal or vertical changes in direction for the ladder, are friction-fitted into slots in the siderail members to provide for rapid, accurate, and rigid assembly. Hangers for either vertical or horizontal surfaces are also provided which snap-fit over the siderail members of the ladder. The rung members are provided with serrated or textured edges to provide a non-slipping attachment location for the cable ties positioning the cables on the ladder.

  • Patent number: 4270161
    Abstract: Lighting apparatus comprising a long span lightweight luminaire beam with a cross section that is substantially in the shape of an equilateral triangle and is formed in multiple sections secured together. One apex of the triangle is pointed downwardly. The side panels of the beam are used as mounting and reflecting surfaces for fluorescent lights or the like, while the ballast and wiring are mounted inside the beam to protect them from weather. The mounting hole for the ballast also serves as the access hole for assembly of the span, and the ballast may be inverted in its mounting for servicing. The beam is supported in an elevated, substantially horizontally extending position by one or more support posts. This apparatus is particularly advantageous for use in illuminating large outdoor areas such as tennis courts.

  • Patent number: 4261100
    Abstract: A method of making an explosion proof contact assembly and the resulting contact assembly are described wherein the electrical contacts are first rigidly mounted on a contact unit or sub-assembly prior to the molding operation. This approach allows complete assembly of the contacts prior to molding of the contact unit within the insulating body, while maintaining required flame path for explosion proof atmospheres. The present invention eliminates post-molding assembly operations which are extremely difficult and substantially raise the cost of producing the contact assemblies.

  • Patent number: 4249353
    Abstract: The fire barrier assembly is comprised of a frame through which one or more electrical cables may be passed and a plurality of sealing elements clamped in the frame in contact with each electrical cable and the frame to provide an airtight barrier. Each element has a plate-like configuration and is comprised of an elastomeric body having intumescent material mixed therewith and opposing end members connected by bolts so that upon movement of the end members toward each other the elastomeric body will expand into intimate engagement with adjacent elements, the frame and each cable passing through the frame. Adjacent elements on opposite sides of an electrical cable are provided with complimentary grooves to define a cylindrical passage for each cable and additional filler elements may be provided without grooves. An external coating of intumescent material is applied to the outer surfaces only of the frame and end members to provide a heat insulating layer.

  • Patent number: 4244545
    Abstract: A cable tray conduit clamp is comprised of a single one-piece body having a 90.degree. sector plate, a square block protruding from one surface thereof with two sides in alignment with the radii of said sector plate and a bevelled boss protruding from the opposite surface of said plate with two sides thereof disposed in alignment with the radii of said sector plate. The extent of said block along the radii of said plate is substantially greater than the extent of said boss along said radii of said plate while the radial extent of said sector plate is substantially greater than the radial extent of said block. A pair of perpendicular intersecting bores are formed through the block and continue outwardly to the curved periphery of the sector plate as open channels in the surface of the plate from which the block protrudes. A J-shaped bolt having a sleeve nut threaded thereon is secured in one of the channels for clamping the body to a flange cable tray.

  • Patent number: 4220986
    Abstract: The ballast and associated electrical equipment for a luminaire are mounted in a compartment of the luminaire housing on an elongated tray which is pivoted at one end to a U-shaped bracket which in turn is mounted on the housing so that the tray may be pivoted outwardly for inspection and servicing of the ballast and associated electrical equipment. Upon detaching the U-shaped bracket from the housing the entire tray may be removed from the housing and the U-shaped bracket can be used as a carrying handle.

  • Patent number: 4195806
    Abstract: A cable tray conduit clamp is comprised of a single one-piece body having two parallel plates extending outwardly from a common post located in one corner of the plates. A plurality of set screws are provided in one plate for securing the flange of a cable tray between plates. The post is provided with a bore in which the shank of a rod having a hooked end is freely rotatable. A locknut is threaded on a opposite end of the shank whereby a conduit may be clamped between the hooked end of the rod and the outer surface of one of the plates at any angle relative to the longitudinal direction of the cable tray to which the clamp is secured.

  • Patent number: 4082141
    Abstract: A ballast can be mechanically and thermally isolated from the mounting plate which acts as a heat sink by securing a pair of L-shaped channels to the bottom of the ballast with the depending leg of each channel being disposed in intimate sliding engagement with the flat surface of a respective C-shaped channel member which is secured to the mounting plate. Vibration damping washers are disposed between the L-shaped channel member and the C-shaped channel member to prevent vibrations from being transmitted from the ballast to the base while still permitting heat dissipation through the superimposed sliding surfaces of the channels.

  • Patent number: 4027151
    Abstract: A luminaire for providing uniform illumination of a horizontal or vertical plane surface is provided with a reflector having three distinct contours to provide optimum distribution of light flux. The first section is cylindrical and extends from 117.degree. to 180.degree. from nadir. The second section is a general contour curve extending from 180.degree. to 270.degree. from nadir and is used to redirect flux in the zone from nadir to 65.degree.. The third section is a general contour curve extending from 270.degree. to 355.degree. from nadir and redirects the flux in the zone from 50.degree. to 65.degree. from nadir. The general contour curves in sections 2 and 3 are defined by fourth degree polynominal equations.

  • Patent number: 3938767
    Abstract: A cable tray has side rails and rungs formed from sheet metal. The side rails have outwardly opening upper and lower grooves which are keystone shaped in that the open side of the groove is narrower than the inner side of the grooves. The lower groove provides an inwardly offset flange along the side rail and the hollow rungs, which are formed with a substantially square cross-sectional shape fit around substantially square portions of the flange which are defined by pairs of spaced vertical slots across the flange. The rung-ends have horizontally aligned rectangular slots through their sides and rung joiners, which have a rectangular cross-sectional configuration are driven through the aligned slots, the joiners having a drive fit between the closed vertical side of the flange and the ends of the aligned slots which are adjacent the end of the rung, thus forcing the rung end against the side rail web.
