Description: Monroe Calculating Machine Co. Fraction Conversion Ruler (Post-1934) This Monroe Calculating Machine Company ruler, dated after 1934, offers a fascinating glimpse into mid-20th-century calculating history. This dual-purpose ruler features both fraction-to-decimal conversion on one side and an EZ-Reed rule with measurements on the other. It was produced by Monroe, a renowned company known for its pioneering work in mechanical calculators and bookkeeping aids, prominently serving business needs throughout much of the 20th century. The ruler, marked with "Tacoma District Office" and managed by F.M. Zelinski, adds an appealing regional connection to collectors in the Northwest. The ruler's compact and practical design suggests it was intended for use in bookkeeping, accounting, or general office environments, making calculations and measurements quick and efficient. In terms of condition, the ruler appears to retain its print clarity and structural integrity. There are some visible marks, possibly from use, which only adds to its authenticity as a genuine office tool from the past. This piece would be a fantastic addition to a collection of historical office equipment or to enhance a display of early-to-mid-20th-century American manufacturing excellence. Monroe Calculating Machine Company was founded in 1912 by Jay Randolph Monroe and contributed significantly to the development of early mechanical calculators. Monroe’s machines were instrumental in transforming bookkeeping and accounting processes in various sectors, from banking to government offices. The company later expanded into producing other office tools like check signers and bookkeeping aids. This ruler stands as a small yet meaningful example of Monroe’s broad influence on the office equipment industry, reflecting its commitment to precision and practical utility. The inclusion of the Tacoma office contact information highlights Monroe's expansive reach across the United States, reflecting its robust network of distributors and service centers.
