James Watt and copy press

1. James Watt and copy press

2. Biography

James Watt was a brilliant Scottish engineer, mechanic, and inventor
The future inventor was born in Greenock, in 1736, on January 19 .
1755 was the most difficult year of the scholar's adolescent life. His
mother died, and his father's health was rapidly deteriorating. By
chance, the family was left without a ship's trade - the main source of
income. The role of primary breadwinner fell on James' shoulders. For
inspiration and a profession he went to London, the heart of Great
Britain. He managed to learn the locksmith's trade program, designed
for 7 years, in one year. The scientist then moved to Glasgow,
Scotland's largest city, intending to devote himself to the invention of
mathematical instruments.

3. the invention of the copy press

• In 1780 Watt invented and patented the portable copy press, which
consisted of a box that had compartments for pencils, pen, ruler, and
paper, as well as a special compartment for copy paper. The metallized box
had a supply of ink and water for 24 sheets of copy paper. A metal cover
was used to clamp the original sheet. The copy sheets were held in a
special compound for 12 hours before starting work. The actual copying
was done by turning the handle of the machine, which rotated two brass
rollers located in the bottom of the case. The original document was placed
on the copying plate between the lifting covers. It was pressed against the
wet copy paper to make an imprint and thus a mirror copy of the
document was obtained on the copying plates, which after 24 hours of
drying was ready for use.

• The company founded by Watt produced such machines until the end
of the 19th century, and such famous people as Benjamin Franklin,
George Washington, and Thomas Jefferson used them in their work.
• In his elderly years the inventor also worked on a machine for copying
sculptural works, the eidograph, a mechanical device that allowed
high-precision copying of bas-reliefs, medallions, statues, and other
things of the most complex shape.
