The Bates Numbering Machine

In the late 19th century, the increasing volume of paperwork in business and legal environments made manual page numbering increasingly impractical. Bates’ machine was developed to address this challenge by providing a more efficient method for applying sequential identifiers to documents. ^[1]

His device introduced a self-inking mechanism with an automatically advancing number wheel, which eliminated the need to advance the numbering manually after each impression. ^[2]

Contemporary accounts and trade records indicate that Bates’ numbering machines became widely used in legal and business environments in the early 20th century. By automating the numbering process, it reduced clerical errors and increased efficiency in document management. The Bates Manufacturing Company produced the device in large quantities for widespread commercial use. ^[3]

Later years and legacy

In the mid-1890s, Edwin G. Bates left Bates Manufacturing Company and later organized a competing firm, originally known as the Bates Machine Company. In 1909, that company adopted the name “Bates Numbering Machine Company,” prompting litigation. A federal court held that the name caused public confusion because “Bates Numbering Machine” had become associated exclusively with the earlier company’s product, and enjoined its use under unfair-competition principles. ^[4]

The Bates Numbering Machine Company was later sold to William C. Roberts and renamed the Roberts Numbering Machine Company. ^[5]

The Bates Manufacturing Company was sold in 1921 to Clarence S. A. Williams, who served as its president until 1958. The company stayed in the Williams family until Thomas M. Williams sold it to the General Binding Corporation (GBC) in 1993. ^[6]

Bates died in 1907.^{[ citation needed ]} His numbering system continued to be used after his death, and its principles were later integrated into digital tools for PDF and electronic record indexing.^{[ citation needed ]}

Recognition

In 1895, Bates received the Longstreth Award from the Franklin Institute for his contributions to office technology. ^[7]

Patents

Bates secured multiple U.S. patents for improvements to numbering machines, including early consecutive numbering (US 484,391, 1892), improved frame and cipher designs (US 587,913, 1897), and mechanisms enabling repeated numbering (US 676,082, 1901).
