did so, because his drawings are complete, and his
specification is also comprehensive.
Whether Saint did or did not build a machine
is a minor matter, because it does not affect the fact
that he is entitled to all the credit of being the father
of this product of ingenuity. His drawings include
many of the fundamental features embodied in the
modern machine without which, so far as knowledge
has carried us, it would be impossible to execute the
work which is accomplished thereby. That Saint’s
machine was perfectly practicable was proved many
years ago by Mr. Newton Willows, who built a machine
strictly in accord with Saint’s conception and from
his actual drawings. This interesting model is still
to be seen in the South Kensington Museum. As a
matter of fact, the London cabinet-maker, in his
patent, described and illustrated three machines capable
of being operated either by hand or power, one of
which, be it noted, was intended essentially for the
making of boots and shoes.
The similarity of the present-day sewing machine
to that evolved by Saint is very striking in many
particulars. There is the horizontal cloth-plate, the
overhanging arm with a vertically working needle
at its extremity, the “ feed,” working automatically
between the stitches, and the cotton or thread wound
on a reel carried on the arm. The most curious
feature, however, is what may be described as the
double needle—or, rather, two needles. Saint did not
contemplate that the needle might be able to drive
its own way through the material to be sewn, because
he introduced a sharp-pointed tool, similar to an
awl, which was moved mechanically, and made the
