•
This Invention relates to an improvement in the manufacture of boots,
shoes, harness bands, and other articles of leather in which stitching is
employed, the improvement having for object to impart additional

or be sunk in grooves or channels as when waxed or other thread is
employed.

NOW KNOW YE, that I, the said Alexander Melville Clark, do hereby

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement, that is to say :-
This Invention relates to an improvement in the manufacture of boots,
shoes, harness straps, and other articles of leather in which sewing is
employed, the object of the improvement being to impart additional
strength to the stitches.
The Invention consists in the employment of copper, brass, galvanized
iron, or other metallic wire instead of using threads of hemp or other
filaments.
I may either employ a single wire or a cord composed of several wires
twisted together.
The metallic stitching may either project on the surface of the leather
or be sunk in grooves or channels therein, as when waxed or other thread
is employed.
The stitching may be done by hand or with the aid of a machine.
Having described the nature of the Invention and the manner of
performing the same, I declare that what I claim as the Invention to be
protected by the herein-before in part recited Letters Patent is, the
manufacture of boots, shoes, harness straps, and other articles usually.
made of sewn leather by sewing with metallic wire or wire cord as a
substitute for thread hitherto used for the purpose, as herein-before
described.
In witness whereof, I, the said Alexander Melville Clark, havo
hereunto set my hand and seal, this Twenty-fourth day of
September, in the year of our Lord One thousand eight hundred
and seventy-four.
Witness,
HARRY SWALES,
