An indirector light fixture is described wherein the fixture is comprised of a reflector housing and a ballast housing connected together by a support arm. The reflector housing may be positioned relative to the ballast housing by movement of the support arm and maintained therein by a ratchet and pawl mechanism or other rotational restriction device. The ballast housing and ballast electronics are connected to the lamp within the reflector housing by ballast feed wires which are maintained internal of the entire fixture thereby preventing the wires from becoming entangled during installation or after installation. Additional structure is provided to further allow adjustment of the head angle relative to the ballast housing.

Luminaire for road lighting

A multiple position luminaire is described having the ability to convert to multiple classifications. The luminaire claimed and described has a multiple position mounting surface on the back of the housing, the housing enclosing a lamp which is surrounded by a reflector. The luminaire mounts to a mounting bracket which allows the luminaire to be mounted in a plurality of positions and angles, the bracket engaging the multiple position mounting surface of the luminaire housing to be positioned either in multiple angle face down positions or multiple angle face up positions.

Multiple position luminaire

A multiple pane glass assembly having at least one pane that is electrically heatable. The glass panes of the assembly are disposed in closely spaced, side-by-side relation with a spacer interposed between adjacent panes. The spacers include a plurality of hollow tubular members disposed near the peripheral edges of the panes with adjacent ends of the tubular members connected by corner key elements. Electrical lead wires extending from an interior electrically heatable surface of one of the panes are directed through respective apertures or passageways in the corner key elements, into the end of a respective tubular member connected to the corner key element, and through the tubular spacer members to a common egress location. The corner key elements are adapted to retain desiccant material in at least some of the tubular members, which together with sealant applied about the periphery of the assembly, enables an air-tight sustantially vapor-free condition to be maintained in the space between panes. Because the electrical lead wires are trained through the tubular spacer members, sealant may be applied about the outer periphery of the assembly and the assembly efficently handled without the impediment of exposed lead wires. The apertured corner key elements further permit easy filling of the interior of the assembly with an inert gas to improve its insulating efficiency.

Glass assembly for refrigerator doors and method of manufacture

The present invention provides an adjustment mechanism by which a luminaire may be adjusted and secured along an arcuate path. The adjustment mechanism includes a mounting bracket, adjustment bolt, adjustment brace, which is attached to the optical housing of the luminaire, and a positioning means, such as an eyebolt. The adjustment bolt is threadably attached to the adjustment brace via a non-rotatable nut. The adjustment bolt, which is disposed through the positioning means, is turned in order to adjust the position of the luminaire. As the adjustment bolt turns, the non-rotatable nut, along with the adjustment brace and optical housing attached thereto, moves along the threaded shaft of the bolt. When the turning of the bolt has ceased, the non-rotatable nut, adjustment brace and optical housing are secured in position by the frictional engagement of the thread of the bolt and the thread of the nut.

Adjustment mechanism for luminaire

A lamp socket mounting and adjusting assembly for an outdoor lighting luminaire in which the lamp socket is secured to an adjustable socket mounting plate which is variably positionable with respect to a socket mounting bracket to vary both the focal point and the focal tilt axis of the lamp. Separate sets of indicia on the socket mounting bracket indicate both the focal axis tilt and the focal point selected for the lamp.

Metal clad switchgear apparatus is taught which includes a skeletal arrangement formed from using "five-fold" channel members with eight unitary corner members. Four type "A" corner members are utilized and four type "B" corner members are utilized. The "A" and "B" corner members are formed from utilizing three identical gusset members in any one of two alternate dispositions. The formed corners are self-aligning and self-jigging relative to the channels which interlink them.

Switchgear with enclosure

A circuit breaker switchgear housing device having a stab positioning system whereby a draw-out circuit breaker having separable contacts is contained in the switchgear housing. A stab positioning system is utilized so as to precisely locate stabs so that a circuit breaker having contact clusters which are electrically attached to the circuit breaker contacts make accurate and uniform contact with the stabs. The stabs are generally a rectangular-shaped bar with one of the ends being rounded off. Cut into two sides of the stab and opposing each other are notches. The stab is inserted into a retainer or positioning washer which has a bayonet-type lock opening into which the stab is inserted and rotated 90°, thereby prohibiting axial movement of the stab with respect to the washer. A retainer or positioning washer having an opening slightly larger than the stab cross-section is used to rigidly position an inserted stab, prohibiting rotational movement with respect to the opening in the stab. An insulating partition which is rigidly attached to the switchgear housing, facilitates the positioning and attachment of the two positioning washers containing the stab. The positioning washers are separated by a ledge contained in the insulating partition.

A telescoping isolated phase bus disconnect switch includes a cylindrical outer housing at ground potential, a pair of coaxial fixed inner conductors at high potential, and a telescoping coaxial movable inner conductor bridging the two fixed inner conductors to perform a switching function. The movable inner conductor is supported on insulating means extending through the housing and mounted upon a movable carriage outside of the housing. The carriage is operated by a drive motor and mechanical linkage both located outside of the housing. The mechanical linkage produces a variable mechanical advantage, increasing its mechanical advantage over the movement range of the switch as the required closing force increases.

Isolated phase bus disconnect switch with grounded operating mechanism

Isolated phase bus duct includes apparatus for adjustably attaching an insulator to the inner surface of a disconnecting switch enclosure to accommodate positional and angular tolerances. The apparatus includes a base member tangential to the surface of the enclosure having a first circular aperture with angled sidewalls. A first circular positioning plate having an angled outer sidewall is seated in the first aperture and includes a second circular aperture non-concentric with the first plate. The second aperture also includes angled side walls and has mounted therein a second circular positioning plate. The second plate has a third circular aperture therein which has angled sidewalls and is non-concentric with the second plate. Seated in the third aperture is a ball plate adapted to be bolted to an insulator. To attach the insulator to the enclosure, the first and second positioning plates and the ball plate are rotated relative to each other and to the enclosure until the ball plate lines up with the insulator. Bolts are then inserted through the ball plate and tightly fastened into tapped holes in a bracket attached to the insulator, thereby fixedly attaching the insulator to the enclosure.
