Sewing Machine

4. Sewing Machine, U. S. Patent 22,143, November 23, 1858, Hiram W. Harkness, Bristol, Connecticut.

The invention relates to moving cloth through a sewing machine using a pressure foot and vertical clamp.

The 8" x 7" x 9" model is made of black painted wood, with gold-colored ornate decorations, that are typical of old sewing machines, and a dull gold colored metal. The machine is made to sit on a table, and appears to be for commercial use. The model is in good condition except for small repairs on a corner of the base and on a part below the base.
