lishing the
history of the manufactured machine than for the minor patented changes.

During the period of the "Sewing Machine Combination," many patentees
attempted to invent and patent "the different machine." This was either
a radical change in style or an attempt to produce a far less-expensive
type of machine. These machines were not always put into commercial
production, but the patent models give an indication of the extent to
which some inventors went to simplify or vary the mechanics of machine
sewing.

The following is a list of those sewing-machine patent models in the
Smithsonian Institution collections:
