The Turtle Back

The first Singer machine specially designed for family sewing was commonly known as "the Turtle Back" and was produced from 1856 to 1859. It had a vibrating overhanging shaft, for actuating the needle-bar, and a reciprocating shuttle. Motion was given to the mechanism from the rocking treadle through a driving wheel carrying a broad leather belt capable of carrying much greater power than was required for its purpose.
