Abstract: Embodiments described herein are directed to a lighting fixture including a lightguide that distributes light from a major surface, a light assembly including light sources arranged linearly, and a frame including a means for providing a force that urges the light assembly against an edge of the lightguide. A standoff or spacer can provide an air gap between a light source of the light assembly and the waveguide edge. In various embodiments, the lighting fixture may incorporate a spring, a spring finger, a spring clip, a screw, or other means for securing the light assembly against the edge of the lightguide. In this manner, substantially all light provided by the light assembly is emitted into the edge of the lightguide. The fixture is formed to accommodate tolerances among elements of the lighting fixture, while maintaining the light assembly securely against the edge of the lightguide.

Abstract: A mechanism is provided for moving a circuit breaker (12) with respect to a circuit breaker connecting apparatus (14) so as to connect or disconnect the circuit breaker from the circuit breaker connecting apparatus. The mechanism includes a draw bracket assembly (29) having a draw bracket (30) constructed and arranged to be mounted to the circuit breaker connecting apparatus (14) so as to be generally adjacent to a side of the circuit breaker connecting apparatus. A guide engaging member (36) is mounted for generally vertical movement with respect to the draw bracket (30). The guide engaging member (30) has a slot structure (42) therein having surfaces constructed and arranged to receive and engage a guide (26) associated with the circuit breaker (12) for moving the circuit breaker with respect to the circuit breaker connecting apparatus (14). A drive member (55) is provided and has a movable element (56).

Abstract: A circuit breaker movement (10) structure is provided for use with a circuit breaker (12) to move the circuit breaker be connected with or be disconnected from a circuit breaker connecting apparatus (14). The movement structure comprises a draw bracket assembly (68) and (70) constructed and arranged to be mounted to the circuit breaker connecting apparatus. A guide assembly (16) is constructed and arranged to be mounted to the circuit breaker (12). The draw bracket assembly includes drive structure constructed and arranged to be actuated to engage the guide assembly and cause the circuit breaker to move with respect to the circuit breaker connecting apparatus. The draw bracket assembly includes a movable structure (108) coupled thereto so as to be moved in a linear manner between first, second, and third positions while maintaining the movable structure in one of the positions.

Abstract: A circuit breaker (10) including a terminal barrier system (140). The terminal barrier system (140) includes a terminal barrier (142) attached to a circuit breaker base (12) at the terminals (16, 18), line and load, of the breaker (10) and a terminal connector (144) mounted in the terminal barrier (142) to align with a terminal (16, 18) of the breaker (10). Several embodiments of the terminal barrier (142) and terminal connector (144) are provided which allow flexibility in combining the various terminal barriers and terminal connectors for a given current rating of the breaker (10). The terminal barrier system (140) protects the terminals (16, 18) of the circuit breaker during short circuit condition operations, prevents pole to pole electrification and prevents accidental contact with live electrical wires in the contacts (42, 44).

Abstract: A unidirectional clutch assembly for use with an operator handle, pinion shaft assembly, a worm gear assembly and a pinion gear assembly of a stored energy assembly for use with a circuit breaker assembly, the operator handle and pinion shaft assembly including an operator handle having an outer handle hub having a first recess for receiving a first end of the pinion shaft assembly, the worm gear assembly fitting over the pinion shaft assembly and the pinion shaft assembly having a second end for receiving a pinion gear assembly, the unidirectional clutch assembly comprising a first unidirectional clutch structure, wherein the first unidirectional clutch structure fits over the first end of the pinion shaft and the unidirectional clutch structure is fitted into the first recess of the outer handle hub; and a second unidirectional clutch structure, wherein the second unidirectional clutch structure fits within the worm gear assembly and over the pinion shaft assembly between the first and second ends of the pi

Abstract: A stored energy apparatus for association with an operating handle of a circuit breaker contains springs that store energy when charged and that release energy when discharged. Energy is stored when a movement translation assembly is moved in a charging direction by an operator gear, and stored energy is released when a release apparatus releases the operator gear, causing the movement translation assembly to move in a discharging direction. The circuit breaker operating handle is moved to ON position by the charging movement of the movement translation assembly, and as stored energy is released, the discharging movement of the movement translation assembly moves the operating handle to OFF position. The operator gear is operated via an operator handle, operator shaft, and pinion gear assembly. The pinion gear assembly has a carrier pivotally associated with the operator shaft and a pinion gear that rotates the operator gear.

Abstract: An adapter plate assembly for mounting a stored energy assembly to a circuit breaker assembly, the adapter plate assembly comprising a mounting plate, the mounting plate comprising a circuit breaker toggle aperture that receives a circuit breaker toggle, at least one mounting aperture for mounting the adapter plate assembly to the circuit breaker assembly, wherein the mounting plate has at least one hinge connector that hingedly connects the stored energy assembly to the mounting plate, wherein the mounting plate further comprises a circuit breaker trip aperture; a trip arm mounting aperture; a trip arm comprising a trip flange at one end for being contacted by a tripping member of the stored energy assembly, a mounting member for rotateably mounting the trip arm to the mounting plate, and a trip extension member, located between the trip flange and the mounting member, that is used to actuate the tripping of the circuit breaker assembly.
