Abstract
An improved fluid level verification apparatus for use on liquid filled containers and configured to reduce inherent mechanical stresses on the inspection tube and resist leakage due to environmental, chemical, thermal or mechanical expansion cycles by using a protective shield member to encase the inspection sight member, and, also, a method for permanently sealing the fluid level detection apparatus.
Claims19
A fluid level verification apparatus comprising:
- a transparent tubular sight member defining a conduit and having oppositely disposed ends;
- a shield member adapted to receive the tubular sight member with oppositely disposed ends, said shield member encasing said sight member;
- a counter bore formed within the shield member inwardly spaced from each respective end;
- first and second end blocks each having a plurality of faces, said end blocks respectively lying perpendicular to the longitudinal axis of a respective end block bore which extends between a pair of oppositely disposed faces;
- an annular skirt, said annular skirt being formed on another face of each said end blocks adjacent to said bore, said skirt including a through bore;
- each of said skirts having a circumferential groove formed about a periphery thereof, said skirts each being respectively engageable with the conduit of the tubular sight member;
- and
- said shield member including an indentation internally forming a secured relationship with said end blocks and said shield member, said indentation forming a detent in said shield member proximate to said groove.

A fluid level verification apparatus comprising:
- a transparent tubular sight member defining a conduit and having oppositely disposed ends;
- a shield member adapted to receive the tubular sight member with oppositely disposed ends, said shield member encasing said sight member;
- said shield member extending longitudinally beyond said sight member at both ends of said sight member;
- said shield member having an opening on at least one side so that said sight member may be externally visible;
- an undercut groove formed within the shield member inwardly spaced from each respective end;
- first and second end blocks each having a plurality of faces, said end blocks respectively lying perpendicular to the longitudinal axis of a respective end block bore which extends between a pair of oppositely disposed faces;
- a nipple, said nipple being formed on another face of each said end blocks adjacent to said bore, said nipple including a through bore, said nipple and through bore being in fluid communication with the conduit of said sight member;
- each of said nipples having an outwardly tapered circumferential exterior surface, said exterior surface engageable with said shield member;
- and
- said shield member including an indentation internally forming a secured relationship with said end blocks and said shield member, said indentation forming a detent in said shield member proximate to said undercut groove.

A fluid level verification apparatus for a fluid container, the apparatus comprising:
- a tubular sight member defining a conduit and having oppositely disposed ends;
- a shield member adapted to receive the tubular sight member having a cylindrical bore;
- a pair of longitudinally spaced apart end members each having hollow interiors, the respective end members each having a cylindrical projection extending therefrom in facing and axially aligned relationship with said sight member;
- each of said projections having an axial through bore communicating with the hollow interior of a corresponding end member and further including a circumferential surface exteriorly thereof;
- and
- said shield member including an indentation internally in secured relationship with said end blocks onto said shield member, said indention forming a detention in shield member at said bore.
3 more elements
A method for assembling a fluid level verification apparatus for a fluid container, said method comprising:
- providing a shield member having an internal bore for encasing a sight member;
- placing said tubular sight member having a through bore within said shield member;
- inserting an end member into substantial engagement with the respective end of the bore of said shield member and into sealing engagement with the sight tube through bore;
- and
- simultaneously indenting opposite sides of the ends of the shield member.

A method for assembling a fluid level verification apparatus for a fluid container, said method comprising:
- providing a shield member having an internal bore for encasing a sight member;
- placing said tubular sight member having a through bore within said shield member;
- inserting an end member into substantial engagement with the respective end of the bore of said shield member and into sealing engagement with the sight tube through bore;
- indenting a first side proximal the end of the shield member;
- and
- indenting a second side proximal the end of the shield member.
3 more elements
A method for connecting respective end members to a shield member in a fluid level verification apparatus thereby sealing the end members to the said shield member, the method comprising the steps of:
- placing outwardly tapered axial projections of the respective end members inside openings formed in the shield member ends;
- abutting the tapered axial projections of said end members to respective sealing means which are positioned inside the shield member between the ends of the tubular sight member and the axial projections of the respective said end members;
- and
- indenting the ends of said shield member so as to clamp said shield member onto the tapered projections of the said end members.
