The South Bend Watch "freezing process": a claim tested

1903–1929 · ADVERTISING, ADJUSTMENT, AND NO PATENT FOUND

The claim: The watch company the Businesses section carries — the South Bend Watch Company, some 1.2 million movements, 1903 to the 1929 crash — passes through local telling with one invention to its name: its balance staffs and hairsprings, the story runs, were hardened and tempered in a patented ice-box process the company called the freezing process, so that its watches kept time from the Klondike to the equator. This section tests the claim against the record, and reports what the record holds. What is documented, richly, is adjustment and showmanship. The company's own advertising demanded that every adjusted South Bend watch "must run alternately in an electric furnace and an ice box with barely a second's variation," through 700 hours of timing and 411 inspections; and from December 1905 the firm ran the most famous watch promotion in America, a South Bend watch frozen in a block of ice in a jeweler's window — begun outside Frank C. Toepp's store on Michigan Street, repeated by jewelers across the country, and followed by a North Pole expedition tie-in and an advertisement of a watch boiled in hot water.

What was not located, in the patent indexes and collector literature searched for this section, is any patent for a freezing or tempering process held by the company or its men: no letters patent for the ice-box hardening appears. The collector record of the National Association of Watch and Clock Collectors adds the working watchmaker's verdict, that South Bend watches were no better at operating in extreme temperatures than those of the other major American makers of the era. The company's genuine distinction in this record is the one the Businesses section already carries — a high-grade railroad-grade movement, sold with showmanship of genius, finished after the 1929 closing by its production chief, W. C. Shelton Sr., who with a small crew completed the movements in process for the creditors (38,000 finished by 1933 in the association's thumbnail history; some 35,000 in the liquidation account of the firm's end, both figures carried as their sources give them).

The freezing process is therefore printed here at the strength it earns: an adjustment regimen and an advertising legend, not a patented invention. The company's design lineage, for completeness, was also not homegrown — its chief designer, Clement Beesley, came from the Columbus Watch Company, and its mechanical superintendent, George H. Hazen, from the Appleton watch works — the South Bend watch was a South Bend manufacture built on other towns' watchmaking, and its inventions belong to the promotion department.
