Abstract
Abstract A moisture meter construction in which a conventional meter assembly is mounted within a housing, an access opening into said housing, a tubular member integrally secured to said housing having an opening therethrough with the opening of the tubular member being aligned with the access opening, an annular chamber surrounding the tubular member, a metallic probe assembly tightly fitted within said annular chamber, a tapered plug member surrounding a portion of the metallic probe assembly being snugly located within said annular chamber, the free end of the probe assembly having an electrical insulator placed within the metallic probe member and a dissimilar metal located interiorly of the insulator with the entire probe assembly being tightly sealed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
134 words
A moisture meter construction wherein a probe assembly is attached to a housing for the moisture meter, the improvement comprising: a tubular extension formed upon said housing having an internal access opening providing access to the interior of the housing; a first electrically conductive member tightly mounted upon said tubular section, said first electrically conductive member being tubular and having an elongated chamber therein; said housing having an annular extension surrounding said tubular section and being spaced therefrom forming an annular internal chamber; a plug member surrounding a portion of said first electrically conductive member with a portion of said plug member to tightly interfit within said internal chamber; an insulator located within the outer end of said first electrically conductive member; and a second electrically conductive member being tightly mounted within said insulator.
Claim 2
Dependent Claim
134 words
A moisture meter construction wherein a probe assembly is attached to a housing for the moisture meter, the improvement comprising: a tubular extension formed upon said housing having an internal access opening providing access to the interior of the housing; a first electrically conductive member tightly mounted upon said tubular section, said first electrically conductive member being tubular and having an elongated chamber therein; said housing having an annular extension surrounding said tubular section and being spaced therefrom forming an annular internal chamber; a plug member surrounding a portion of said first electrically conductive member with a portion of said plug member to tightly interfit within said internal chamber; an insulator located within the outer end of said first electrically conductive member; and a second electrically conductive member being tightly mounted within said insulator.
Claim 3
Dependent Claim
82 words
The moisture meter apparatus as defined in claim 1 wherein: a portion of said plug member located within said internal chamber being tapered so that the cross-sectional diameter of the outermost portion of said portion being of smaller diameter than the innermost section of said portion, whereby as said portion is inserted within said internal chamber there is achieved a progressively tighter interconnection between said portion and said annular extension of said housing and said first metallic member about said tubular extension.
Claim 4
Dependent Claim
47 words
The moisture meter apparatus as defined in claim 2 wherein: said annular extension having on its outer end thereof an annular raised member, an annular recess formed within said plug member, said annular raised member to interlockingly cooperate within said annular recess forming a tight interconnection therebetween.
