Patent number: 8304672Abstract: A motorized racking mechanism for racking a circuit breaker into and out of switchgear/board equipment allows for breaker service without operator proximity to the switchgear. A motor fixed to a cradle that receives a circuit breaker is coupled to a power transmission system that turns a control screw. The control screw laterally moves a crown-wheel device that causes the circuit breaker to be moved among a remove, test, and connected positions in response to a button arm being depressed via a front panel of the cradle. The button arm can be depressed under wireless remote control. A solenoid is coupled to a crank detent actuator that includes the button arm, and a wireless module actuates the solenoid, which moves the button arm, causing the motorized movement of the circuit breaker as if the button arm had been manually depressed. Indicator lights are visible on the front panel to indicate the position of the circuit breaker relative to the cradle.Type: GrantFiled: December 21, 2009Date of Patent: November 6, 2012Assignee: Schneider Electric USA, Inc.Inventors: Gregory B. Lee, Christopher K. Goble

Publication number: 20120011675Abstract: A tool is designed to simultaneously remove and catch the materials used for finishing acoustical ceilings, thereby greatly reducing or, in some cases, eliminating the need for extensive drop cloth and plastic coverage of the room's interior and furnishings. The tool may reduce or eliminate the laborious task of cleaning up the removed acoustical ceiling material, which, with conventional methods, often dries on surfaces before clean-up begins. The tool may include a scraper to remove the acoustical ceiling material and a hollow body cavity to accumulate the removed material. The tool may be designed to be ergonomically friendly, lightweight and easy to use within a broad range of prestidigitation.Type: ApplicationFiled: July 13, 2010Publication date: January 19, 2012Inventor: Christopher K. Goble

Patent number: 5539167Abstract: A blade suspension assembly for a circuit breaker comprises a pivot pin, a torsion spring, an elongated blade, and a blade carrier. The torsion spring includes a lateral middle section, a pair of end legs disposed on opposite sides of the middle section, and a lateral hole extending therethrough. The blade includes an electrical contact mounted thereto, a lower bearing surface, and a lateral circular aperture. The blade carrier includes first and second pairs of bearing surfaces. To assemble the blade suspension assembly, the torsion spring is placed over the blade with the lateral middle section abutting the lower bearing surface of the blade, with the end legs disposed on opposite sides of the blade, and with the lateral hole in the torsion spring disposed in line with the circular aperture in the blade. Next, the pivot pin is inserted through the lateral hole in the torsion spring and through the circular aperture in the blade.Type: GrantFiled: February 14, 1994Date of Patent: July 23, 1996Assignee: Square D. CompanyInventors: Teresa I. Hood, Joel L. Miller, John M. Winter, Christopher K. Goble

Patent number: 5504291Abstract: A contact blade assembly for a circuit breaker comprises a blade carrier, an elongated blade, and a toggle spring. The blade carrier includes a blade pivot and a first spring pivot. The elongated blade has an electrical contact mounted thereto and includes a second spring pivot. The blade is rotatably mounted to the blade pivot of the blade carrier for rotation between a closed position and an open position. The toggle spring is connected to the first spring pivot at one end and to the second spring pivot at the other end. The first spring pivot, the second spring pivot, and the blade pivot are arranged such that a toggle condition associated with the rotation of the blade relative to the blade carrier corresponds to the blade pivot being located in line and between the first and second spring pivots. The toggle spring biases the blade away from the toggle condition in a first direction while the blade is disposed in the closed position.Type: GrantFiled: February 14, 1994Date of Patent: April 2, 1996Assignee: Square D CompanyInventors: Christopher K. Goble, Joel L. Miller

Patent number: 5424699Abstract: A blow-off terminal includes a flat conductive tang, a flat conductive input section, and a flat conductive output section. The input section includes a pair of generally parallel U-shaped strips. Each of the pair of strips includes first and second end portions and a center portion bridging the first and second end portions. The first and second end portions and the center portion of each of the pair of strips are generally co-planar, and the tang and the output section are generally co-planar. The output section is elongated and includes first and second ends, the first end being disposed closer to the tang than the second end. The first end portions of the strips are connected perpendicular to opposite sides of the tang, and the second end portions are connected perpendicular to opposite sides of the second end of the output section. A stationary contact is mounted to the surface of the output section.Type: GrantFiled: February 14, 1994Date of Patent: June 13, 1995Assignee: Square D CompanyInventor: Christopher K. Goble

Patent number: 5130684Abstract: A bimetallic thermal release element (34) for use in a thermally actuated tripping mechanism, and in particular used in electrical circuit breakers (10) wherein the load current is passed through the bimetallic element has a self-aligning floating latch member (141) configured to engage the release member and to disengage therefrom when the bimetallic element bows a sufficient amount at a given temperature or current. The bimetallic element is preferably an elongated member supported at its ends (128, 130) by side members (28, 42). An increased sensitivity is imparted to the bimetallic element by mounting the side members for rotation to accommodate the bowing.Type: GrantFiled: March 27, 1990Date of Patent: July 14, 1992Assignee: Square D CompanyInventors: Gary W. Scott, Christopher K. Goble, David Pearson

Patent number: 5126517Abstract: A current interrupter in which a first movable, insulating, gear carries a contact blade. The blade extends out from this movable gear and forms a contact which makes and breaks with a stationary contact upon movement of the gear. A second insulating gear has a set of teeth which engage the teeth on the first gear. The second gear has a cavity into which the extended contact fits. Movement of the first gear in a direction to break the contact, causes the engaged teeth to drive the extended contact into the cavity, thereby insulating the movable contact from the stationary contact. The interlocking gear teeth create a tortuous path for the arc and provide a large over surface distance for dielectric strength.Type: GrantFiled: September 11, 1990Date of Patent: June 30, 1992Assignee: Square D CompanyInventors: Ramon O. Torres-Isea, Gary W. Scott, Christopher K. Goble

Patent number: 4969063Abstract: A three-condition constantly illuminated status indicator is provided in a circuit breaker to provide three luminesce displays indicating that the breaker is in the on, off or tripped condition. Associated electrical circuitry employs diode-steered capacitive charging elements for selective, common or simultaneous energization of a three-color light emitting diode display without acting as a bypass around the circuit breaker, thus eliminating shock hazard. Selective energization of the light emitting elements is achieved by auxiliary switching means operable to a plurality of switching conditions according to switching conditions of the circuit breaker. The capacitors serve as an impedance to current for the light emitting diodes, eliminating the need for ballasting resistors, resulting in a cooler operating, lower power consumption unit.Type: GrantFiled: May 16, 1989Date of Patent: November 6, 1990Assignee: Square D CompanyInventors: Gary W.
