Patent number: 8870609Abstract: An attachment apparatus is usable as a line terminal or load terminal of a circuit interrupter to enable a conductive element that includes a ring terminal to be electrically connected with a conductor of a circuit interrupter. The attachment apparatus employs a conventional lug which serves as a connector. The lug includes a threaded engagement element. The attachment apparatus further includes a connection element having a threaded receptacle that is structured to receive a shank of a threaded fastener. The shank is received through a hole formed in a ring terminal and is further threadably receivable in the receptacle of the connection apparatus to enable the ring terminal and a wire connected therewith to be reliably electrically connected with a line conductor or a load conductor of the circuit interrupter. The threaded shank can be unthreaded from the connection element to permit removal of the ring terminal and associated wire.Type: GrantFiled: October 19, 2012Date of Patent: October 28, 2014Assignee: Eaton CorporationInventors: William George Eberts, Kenneth D.

Patent number: 7238910Abstract: A crossbar assist mechanism is for a circuit breaker including a housing, a movable contact, a stationary contact, and an operating mechanism. The operating mechanism includes a crossbar, a carrier coupled to the crossbar, and a movable contact arm which is pivotably cooperable with the carrier. The movable contact is disposed on the movable contact arm. The crossbar moves the carrier and the movable contact arm, thereby moving the movable contact into and out of electrical contact with the stationary contact. The crossbar assist mechanism includes an electrically conductive member electrically interconnecting the carrier and the movable contact arm to a load terminal. A spring disposed between the crossbar and the electrically conductive member biases the crossbar from a first position corresponding to the movable contact and the stationary contact being separated, toward a second position corresponding to the movable contact being in electrical contact with the stationary contact.Type: GrantFiled: May 15, 2006Date of Patent: July 3, 2007Assignee: Eaton CorporationInventors: Michael P. Puskar, Robert W. Mueller, William E. Beatty, Kenneth D. Kolberg

Patent number: 5894259Abstract: A solenoid type magnetic trip assembly for a molded case circuit breaker includes an armature biased against an adjustable stop by a tension spring to set the initial gap for the magnetic trip, so that the spring bias remains constant for the full range of the initial gap. The armature includes an elongated magnetically permeable member mounted by a frame to slide longitudinally along a pair of guide rails. The frame defines a trip surface axially aligned with the elongated magnetically permeable member which engages a trip arm on a trip bar to trip the circuit breaker in response to a predetermined level of overcurrent. A bimetal providing a thermal trip function is cantilevered from a support spaced from the trip bar by the armature, but has a terminal portion at the free end projecting toward the trip bar and through which the elongated magnetically permeable member of the armature extends.Type: GrantFiled: April 14, 1997Date of Patent: April 13, 1999Assignee: Eaton CorporationInventors: Kenneth D. Kolberg, Mark A. Juds

Patent number: 5613275Abstract: An adjusting knob assembly includes a knob member having a knob and an axially extending shaft. A support bracket has an aperture defined in part by a gapped ring section formed by a pair confronting arcuate fingers. The shaft and the aperture have complimentary, longitudinally extending, circumferentially distributed flat surfaces, which provide discrete angular positions for the shaft when the complimentary flat surfaces are in register. Preferably, the gap between the confronting fingers is sized, and the arcuate fingers have a compliance sufficient that the shaft may be passed laterally through the gap and snapped into the aperture. Any one of a plurality of interchangeable cam members can be press fit on to the end of the shaft.Type: GrantFiled: February 27, 1996Date of Patent: March 25, 1997Assignee: Eaton CorporationInventors: Kenneth D.

Patent number: 5493085Abstract: A terminal connection for a flat stab of an electrical switch includes a spring clip which retains a nut in alignment with an aperture in the flat stab. The spring clip is fabricated from a strip of resilient electrically conductive material and has a top wall with a central aperture, side walls extending downward from the top wall and having slots therein, an end wall extending downward from the top wall and a bottom wall cantilevered forward from the bottom of the end wall under the top wall and between the side walls. A square nut is retained in the spring clip with its tapped hole aligned with the aperture in the top wall and with either an aperture or a depression in the bottom wall. The fastener assembly clips onto the end of the flat stab with the stab between the nut and the top wall of the spring clip. A screw passed through the apertures in the top wall and the flat stab engages the nut to secure a conductor to the stab.Type: GrantFiled: February 17, 1995Date of Patent: February 20, 1996Assignee: Eaton CorporationInventors: Kenneth D.

Patent number: 4831703Abstract: Both an apparatus and method for plugging a conduit, such as a tube in the tubesheet of a nuclear steam generator, is disclosed herein. The plugging apparatus generally comprises an inelastically expandable plug that contains a fluid-receiving cavity, and an expansion means including both a source of pressurized hydraulic fluid and a pull-rod member having a piston for advantageously applying both a radially expansive force and a compressive force to the plug at the same time in order to inelastically expand it into sealing engagement with the inner wall of a tube. In the apparatus of the invention, the compressive force exerted on the plug by the pull-rod member not only serves to inelastically deform the plug into a radially expanded shape, but is also used to seal the open end of the plug so that the pressurized hydraulic fluid admitted within the cavity of the plug will not escape.Type: GrantFiled: June 3, 1988Date of Patent: May 23, 1989Assignee: Westinghouse Electric Corp.Inventors: John J. Wilhelm, Kenneth D. Kolberg, William G. Cole, Gregory L. Calhoun
