The Singer cabinet works: an invention record of manufacture, not of patents

1868–1955 · NO SOUTH BEND SINGER PATENT; THE INNOVATION WAS THE MAKING

The honest entry: The Singer cabinet works — from 1901 until the mid-1950s the largest plant in the Singer world, turning out roughly three-quarters of the world's sewing-machine cabinets at its peak, as the Businesses section carries — would seem an obvious place to look for South Bend patents. This section looked, and states the result plainly: no letters patent in the name of a South Bend Singer man was located in the record reached, and the cabinet patents that exist inside the Singer system belong to men of other cities and earlier decades — the patent lists of the sewing-machine art carry, for instance, No. 13,499 of 28 August 1855 to W. H. Marshall and F. A. Ross for a sewing-machine cabinet, and No. 22,464 of 28 December 1858 to W. P. Uhlinger for the drop cabinet, neither with any South Bend connection.

The works' superintendent, Leighton Pine — the man who ran the plant for half a century and gave the city its art museum's building — appears in this record as a manager and a patron, not as a patentee, and the entry refuses to promote him into one. What the South Bend works actually contributed to the art was process at scale, and one material innovation of the Singer system ran through its product line in these years: the moulded three-ply plywood covers and cases the company made from 1884 into the 1950s. The Victoria and Albert Museum's label for a Singer plywood cover states the scale in terms no advertisement would dare: the Singer Manufacturing Company was, in the museum's judgment, "almost certainly the world's largest plywood furniture producer from the 1880s to the 1950s," using the material across its tables, cabinets, and covers.

The plywood work was a company-wide technology rather than a South Bend patent, and it is credited at exactly that level here. The rest of the works' inventive record is the plant itself — the largest woodworking operation of its kind, served by a railroad the company built for it, the New Jersey, Indiana & Illinois — the Businesses section's ground. A section on invention serves the truth best by printing this entry at its true size: the cabinet works changed how the world's sewing machines were housed, and it left almost no patent paper in its own town's name.
