摘要： A breather assembly having an outer housing, an insert in the upper portion of the housing, a porous metal disc adjacent the insert, a plurality of glass beads adjacent the disc, a spacer cup adjacent the beads and a washer acting as a plug adjacent the spacer cup. The housing has an upper closed end and a lower open end, the washer being press fitted into the open end to retain the cup, beads, disc and insert. There are two oppositely disposed openings in the housing which directly communicate to abutting converging openings in the spacer. The junction of the narrow end of the converging openings communicate with a central vertical opening, a space between the insert and the housing, a recess in the insert, another vertical opening in the insert which is spaced from the first vertical opening. The bottom end of the spaced vertical opening communicates with the porous metal disc. An air passage is created from the environment exterior to the housing through the converging openings, the central vertical opening, the space, the recess and the spaced vertical opening, the disc, the beads, around the cup and through the central opening of the washer. The converging openings provide for a Venturi effect which allows air to pass into and out of the breather apparatus but which prevents water from entering the enclosed electrical system.

摘要： An electrical plug for an associated electrical device for use in hazardous locations, comprising a metal housing; a nonconductive plug base holding at least two conductive terminal prongs connected to conductor wires passing through the housing and connected at their other end to the electrical device; and a plastic sleeve for preventing contact between the conductor wires and the metal housing, providing a bearing surface for the plug base and an elastomeric gasket compressed therebetween, cooperating with a reversible clamp to mechanically grip the conductor wires and prevent their separation from the terminal prongs, and providing simple measurement of a predetermined length of wire between the clamp and each terminal. A rubber grommet provides a moisture-resistant seal along the back end of the plug housing. A label plate may be affixed to the exterior surface of the plug housing by means of peened over posts that do not interfere with the integrity of the plug housing.

摘要： A corrosion resistant hub with a metal insert and an elastomeric outer shell forms a coupling to join a conduit to an enclosure. The metal insert which serves as a grounding mechanism for the conduit comprises internal threads, located near the conduit receiving end of the insert, to connect the conduit to the hub, and external threads, located at the wire exiting end of the insert to connect the hub to the enclosure. A shell made of semi-rigid elastomeric material is molded onto the outer surface of the metal insert. The shell has an annular flange, a hexagonally shaped torquing section and a collar. The annular radial flange forms a reliable seal of the interface between the insert and the enclosure. The collar has a lip that forms a first seal of the junction between the conduit and the insert and internal threads that engage the conduit to provide a second seal of the junction between the conduit and the insert. The hub also has a bushing which is unitary with the shell via an aperture in the insert. The bushing is molded into the inner surface of the metal insert at the wire exiting end of the insert.

摘要： An explosion proof drain for incorporation into an enclosed electrical system including a hollow housing with an opening at an upper end and an annular flange circumscribing a smaller opening at a lower end. A porous, metallic disk is force fitted into a bore in the housing and seated against the annular flange. A filling material is poured into the bore of the housing and is supported by the porous metallic disk. A second porous, metallic disk is force fitted into the opening in the upper end of the drain to ensure that the sand does not exit the drain.

摘要： An actuator means for an electrical switch concealed in a housing and operated by a handle externally mounted to the cover thereof, whereby, upon closing the cover, the actuator automatically moves in a rectilinear direction to locate the toggle operating lever of the switch and rotatably moves the externally viewed handle to preposition it to indicate the energization state of the switch. Alternatively, the actuator permits operation of the switch by rotating the externally accessible handle. This invention is especially suited to circuit breaker switches contained in explosion-proof or hazardous location-rated enclosures.
