  • Patent number: 6857315
    Abstract: An armored sight gauge assembly of the type having a sight tube that is placed between first and second spaced apart fittings to show a liquid level comprising an elongated main body positioned between and permanently connected to the first and second fittings. The main body incorporates a flanged U-shaped frame member to which there is removably affixed a transparent sight tube shield. A sight tube assembly substantially surrounded by the flanged U-shaped frame member on three sides and is insertably captured by the first and second fittings. A valve assembly and ball check shutoff is incorporated within the internal portion of each of the first and second fittings as is a misalignment union which is removably attached to each fitting.

  • Patent number: 5442959
    Abstract: A sight gauge is placed between two spaced apart compression type fittings connected to a vessel to show the liquid level in the vessel. The sight gauge has an elongated tubular transparent tube shield and a slightly longer elongated transparent sight tube that is received within the sight tube shield. An upper and a lower connection plate are each telescopically received by the sight tube, the sight tube shield being captured between the connection plates. An upper and a lower nozzle member each has an opening to respectively capture the upper and lower ends of the sight tube. An upper and lower elastomeric O-ring is received on the sight tube positioned between the connection plates and the nozzle members. Bolts secure the nozzle member to the compression plates to squeeze the O-rings against the sight tube so that the sight tube retains and supports the tube shield. Each nozzle member has an elongated tubular portion that can be received in a compression fitting.

  • Patent number: 4693117
    Abstract: A shielded tubular gauge for placement between two spaced apart fittings connected to a vessel to show the level of liquid in the vessel, including an elongated frame having a U-shaped cross-sectional configuration, a connection housing secured to each end of the frame and each having an opening therethrough, the opening being internally threaded in the outer portions thereof, a transparent tubular member received in the frame and in the housings openings, a packing nut received in the threaded opening in each of the housings, each of the packing nuts having a portion extending beyond the housing providing a cylindrical surface receivable in the fittings attached to the vessel, an elastomeric packing ring within each housing engaged by the packing nut and compressed against the exterior of the tubular member and a protective shield, such as of transparent material like polycarbonate or expanded metal, received in the frame providing protection for the tubular member.
