Abstract
A small mechanical weighing scale capable of weighing relatively light, flat articles such as envelopes. The scale contains a slidable pullout flexible beam that is adapted to hold a thin flat article. The tape will break away in accordance with the weight of a held article as the tape is extended from the housing of the scale.

A weighing scale comprising:
- a housing having a first opening therein,
- a flexible beam supported within said housing and having a variable portion of its length extending through and beyond said opening,
- said portion having means for supporting an article to be weighed, wherein said flexible beam will bend upon being extending and having an article attached thereto the length of the flexible beam at the moment of bending being inversely proportional to the weight of such article.
A weighing scale comprising:
- a longitudinally extending housing having a first opening therein and a longitudinally extending channel located in the interior thereof and adjacent said first opening,
- a flexible beam slidably supported within said channel and having a variable portion of its length extending through and beyond said opening and exterior to said housing,
- said portion having means for supporting an article to be weighted, wherein said flexible beam will bend upon being extending from said housing and having an article attached thereto, the length of said flexible beam at the moment of bending being inversely proportional to the weight of such article.
