UNKNOWN - "Watt's Steam
Engine "
The generally held belief
that James Watt perfected
his steam engine in Bo'ness
carries a grain of truth,
but little more than a
grain. He was encouraged by
Doctor Roebuck to come to
Bo'ness to build a steam
engine which would pump out
water from the pits and
allow miners to get the
seams of coal under Bo'ness
and district. He enjoyed
some little success and more
than enough failures.
Born in Greenock, he worked
as a struggling mathematical
instrument maker at Glasgow
University when a friend of
Dr Roebuck spoke to him of
the problems associated with
pumping water from the pits
and mines at the same time
being suffered by his
Bo'ness friend.
At this time, Dr Black spoke
to Dr Roebuck of this
brilliant young man who had
invented the steam engine.
On hearing this, Roebuck
wrote Watt. At first he was
doubtful of the principle of
the engine and induced him
to revert back to the old
concept.
Watt, much against his own
convictions tried the older
methods, but failure after
failure resulted in Watt
becoming depressed at his
lack of success.
Up to this time, Roebuck and
Watt had never met. The
doctor urged him to travel
to Bo'ness, but Watt at that
time did not keep good
health and reluctantly
refused the invitation.
Agreeing to meet at Carron
Iron Works in Falkirk where
Roebuck had more than a
passing interest, Watt sent
on a series of drawings for
a steam cylinder to be cast
there. It contained several
faults, wasn't correct in
line and twisted beyond
reasonable use.
The piston rod was cast in
Glasgow, but Watt was
reluctant to send it off as
people did not take kindly
to mechanism in those days.
It subsequently was sent off
in a box in July of 1766.
In 1776, Roebuck was so
taken by Watt's ideas that
he undertook to give Watt
£1000 to carry on with the
work. His return on that
was to be two-thirds of the
property of the invention.
In 1778, Watt produced an
engine with an eight-inch
cylinder. Unfortunately
mercury found its way into
the machine playing havoc
with the lead content.
He proceeded to patch up
this engine and one month
later, he rode into Bo'ness
with the engine to be housed
in a small "But and Ben,"
the remains of which stand
to this day.
The model was successful and
it was agreed that a patent
should be taken out which
meant a travel to
Berwick-on-Tweed to obtain
the protection papers.
Castings were made in Carron
and Glasgow which doesn't
appear to throw the local
moulders into a good light.
Watt used this period to
perfect his steam operated
pumps and his reputation
captured the interest of
Matthew Boulton of
Birmingham.
These firms had the
resources available to them
to allow Watt to progress
further in his work with the
Birmingham firm benefiting
from the experience James
Watt had gained in Bo'ness
under the patronage of Dr
Roebuck.
The firm of Watt and Boulton
was formed and James Watt as
we know him now prospered
never forgetting the
assistance given him by Dr
Roebuck and his 12-year
association with Bo'ness.
The pump stationed at
Taylor's Pit was described
as one of the fastest ever
seen and worked continually
for many years. Yet another
at the Temple Pit worked
pumping water out of this
"Damp" pit for many years.
The present cylinder at
Kinneil is one of a number
which lay at the site of the
former School Yard Brae
Pit. The Town Council in
the late 40s decided that it
represented an industrial
relic of considerable value
which was part of the
history of Bo'ness. They
moved it to stand beside the
cottage at Kinneil.
While it is quite wrong for
anyone to claim that Watt
discovered the Steam Engine
in Bo'ness, it is perfectly
right to say that Bo'ness
played a big part in the
perfection of a part of the
industrial revolution in
Britain. James Watt had
good reason to thank Bo'ness
and in Particular Dr John
Roebuck ( 1718 - 1794 ).
