Abstract

491,380. Weighing-apparatus. RULKE, G. Feb. 27, 1937, No. 5952. [Class 143] A letter balance or like scale formed of strip material has a fulcrum edge a and an abutment portion b which limits the tilting to a very small angle when the balance rests on an horizontal surface. The letter is carried by a two-jawed pivoted clip c and hangs clear of the supporting surface during weighing, In a modification, the abutment portion b is replaced by a succession of fulcra-similar to a located on a curve of large radius. The long arm of the balance may be formed as a letter opener. British Specification 283,074, [Class 143], and U.S.A. Specification 1,843,934 are referred to.
