late 19th century German lockstitch machine has its name "Simplex"
embossed in the castings. The machine is also known by the name
of "Volksnaehmaschine". Although of compact dimensions,
it should be regarded as a small portable rather than a true
miniature. The cloth plate is, however, of diminutive proportions
and its shuttle capacity is very limited - being akin to that
of the Pocket Moldacot. The machine's main motion is obtained
through the use of two large lever arms, powered by a forward-facing
crank. Other features include a spring-pressed take-up lever,
which is pivoted on the overhanging arm.
The design was patented in 1891 by Max Harff and Ewald Bruecker,
the latter being an engineer and inventor from Cologne. It was
he who convinced Harff, a local entrepreneur and factory owner,
to produce the machines at his Works.
With known extant examples in single figures, this slightly
odd looking machine is highly sought after by today's dedicated
