Latest Patents

Breckenridge holds a patent for a "Sealed Lay-In Conduit Duct." This invention is an oil-tight electrical conduit duct that features U-shaped sealing collars. These collars telescope into adjacent ends of aligned open-ended sheet metal duct sections, which are generally U-shaped in cross-section. The design includes unobstructed open sides throughout the length of the duct, which can be closed by a movable sealing trough cover. The sealing collars and duct sections have telescoping bottom and side wall portions, each equipped with elongated cooperating interengaging rib and groove elements. These elements are aligned and extend normally to the longitudinal axis of the duct sections. Each collar member carries a sealing element that extends throughout its length, effectively covering and sealing the juncture of the adjacent ends of the trough sections. Additionally, a closure member with sealing elements covers the open area between the ends of the side walls of each collar member, working in conjunction with the sealing trough covers to complete the seal of the duct.
