In 1802 Bramah obtained a patent for woodworking machinery second only
in importance to that granted Bentham in 1791. Like Bentham, he aimed
to replace manual labor “for producing straight, smooth, and parallel
surfaces on wood and other materials requiring truth, in a manner
much more expeditious and perfect than can be performed by the use
of axes, saws, planes, and other cutting instruments used by hand in
the ordinary way.” His tools were carried in fixed frames and driven
by machinery. In his planing machine, one of which was running in
the Woolwich Arsenal for fifty years, the cutter-head, which carried
twenty-eight tools, was mounted on a vertical shaft and swept across
the work in a horizontal plane. He used this same method in planing
the metal parts for his locks, which corresponds, of course, to our
modern face-milling. He provided for cutting spherical and concave
surfaces and used his device for making wooden bowls.
In 1806 he devised an automatic machine which the Bank of England used
many years in numbering their banknotes, eliminating error and saving
the labor of many clerks.
Maudslay was in his employ from 1789 to 1797. He was getting as
superintendent 30s. ($7.50) a week. A growing family and “the high
cost of living” rendered this insufficient and he applied for more. He
was refused so curtly that he gave up his position and started in for
himself in a small workshop on Oxford Street in London. Later he took
Field in as partner under the firm name of Maudslay & Field.
In 1813 Bramah engaged another man who later had a great influence,
Joseph Clement. Clement soon became his chief draftsman and
superintendent. Salaries had gone up somewhat by that time and he had
an agreement for five years starting on the basis of three guineas a
week with an advance of four shillings each year. At Bramah’s death not
long after, his sons took charge of the business, and soon grew jealous
of Clement’s influence. By mutual consent the contract was terminated
and he went at once to Maudslay & Field as their chief draftsman.
Later he, too, set up for himself and had an important part in the
development of the screw-cutting lathe, the planer and standard screw
threads. Whitworth was one of his workmen and Clement’s work on taps
and dies formed the basis of the Whitworth thread.
Bramah died in 1814, at the age of sixty-six. He was a man of widely
recognized influence, a keen and independent thinker, a good talker,
and, though it might not appear from what has been said, a cheery and
always welcome companion. He left a reputation for absolute business
integrity and the quality of his workmanship was unrivaled until his
later years, when he was equaled only by those he had himself trained.
He gave the world some great and valuable devices and paved the way for
others. His influence on modern tools can probably never be accurately
judged, but Smiles’ tribute to him is as true today as when it was
written, two generations ago:
