Filed:

Mar 29, 2007

Appl. No.:

11/693159

Inventors:

Andrew L. Gottschalk - Pittsburgh PA, US
Paul R. Rakus - Chippewa Township PA, US
David A. Parks - Baden PA, US

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H01H 5/00

US Classification:

200400, 200401

Abstract:

Within a closing assembly that utilizes a ram assembly having a spring driven ram body, an energy dissipating spring seat assembly is provided. The ram body is mounted on a guide assembly having at least one pin. The guide assembly also includes a base plate and a stop plate. A ram assembly spring is disposed between the ram body and the base plate and is structured to bias the ram body toward the stop plate. The spring seat assembly includes a spring seat bracket and a spring seat. The spring seat is, preferably, a generally flat, plate-like leaf spring that is disposed between the ram assembly springs and the base plate of the ram body. The spring seat is sufficiently rigid so as to not deflect fully under the force created by the compressed ram assembly springs, but not so rigid as to resist deflecting under the force created when the ram body impacts the stop plate.

International Classification:

H01H 5/00

US Classification:

200400

Abstract:

A charging handle apparatus includes a two-piece support apparatus that is disposed on a handle assembly and that is engaged with a gear. One of the two pieces is movable with respect to the first piece. The second piece of the support apparatus includes a number of engagement structures that are engaged with the gear and that retain the gear in a given position with respect to the handle assembly. The charging handle apparatus thus can be provided as a pre-assembled component that is readily mountable to a shaft of a circuit interrupter.

Assignee:

Marine Muffler Corporation - Apopka FL

International Classification:

B63H 2110

US Classification:

440 89

Abstract:

A marine engine exhaust system and method utilizes first and second enclosed, generally tubular chambers having generally parallel lengthwise dimensions and internal intermediate exhaust passageways spaced along the lengthwise dimension of the second chamber for circulating the exhaust gases through the first chamber, laterally through the intermediate exhaust passageway into the second chamber, along the lengthwise dimension of the second chamber and thence out of an outlet exhaust passageway which passes through the second chamber wall. An outer portion of the second chamber is integrally formed with an outer portion of the first chamber to enhance structural integrity.

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H01H 902
H01H 1304

US Classification:

335202

Abstract:

This concerns a molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. The trip unit is removable. In this case the trip unit is insertable into a trip unit region in the case of the circuit breaker from the top or end thereof. The trip unit is then joined to an internal electrical conductor by way of a bolt and an internally fixed nut. The bolt can be driven into the nut through the trip unit conductor and the internal conductor from a position external to the circuit breaker case. The trip unit can be inserted into the trip unit conductor from a point above the circuit breaker case or vise versa. The trip unit has a securement nut built into its case.
