idea soon suggested itself of moving the press by machinery; or
to reduce the several operations to one rotary motion; to which
the first mover might be applied。 Whilst Koenig was in the
throes of his invention; he was joined by his friend Andrew F。
Bauer; a native of Stuttgart; who possessed considerable
mechanical power; in which the inventor himself was probably
somewhat deficient。 At all events; these two together proceeded
to work out the idea; and to construct the first actual working
printing machine。
A patent was taken out; dated the 29th of March; 1810; which
describes the details of the invention。 The arrangement was
somewhat similar to that known as the platen machine; the
printing being produced by two flat plates; as in the common
hand…press。 It also embodied an ingenious arrangement for inking
the type。 Instead of the old…fashioned inking balls; which were
beaten on the type by hand labour; several cylinders covered with
felt and leather were used; and formed part of the machine
itself。 Two of the cylinders revolved in opposite directions; so
as to spread the ink; which was then transferred by two other
inking cylinders alternately applied to the 〃forme〃 by the action
of spiral springs。 The movement of all the parts of the machine
were to be derived from a steam…engine; or other first mover。
〃After many obstructions and delays;〃 says Koenig himself; in
describing the history of his invention; 〃the first printing
machine was completed exactly upon the plan which I have
described in the specification of my first patent。 It was set to
Work in April; 1811。 The sheet (H) of the new Annual Register
for 1810; 'Principal Occurrences;' 3000 copies; was printed with
it; and is; I have no doubt; the first part of a book ever
printed with a machine。 The actual use of it; however; soon
suggested new ideas; and led to the rendering it less complicated
and more powerful〃'2'
Of course! No great invention was ever completed at one effort。
It would have been strange if Koenig had been satisfied with his
first attempt。 It was only a beginning; and he naturally
proceeded with the improvement of his machine。 It took Watt more
than twenty years to elaborate his condensing steam…engine; and
since his day; owing to the perfection of self…acting tools; it
has been greatly improved。 The power of the Steamboat and the
Locomotive also; as well as of all other inventions; have been
developed by the constantly succeeding improvements of a nation
of mechanical engineers。
Koenig's experiment was only a beginning; and he naturally
proceeded with the improvement of his machine。 Although the
platen machine of Koenig's has since been taken up a new; and
perfected; it was not considered by him sufficiently simple in
its arrangements as to be adapted for common use; and he had
scarcely completed it; when he was already revolving in his mind
a plan of a second machine on a new principle; with the object of
ensuring greater speed; economy; and simplicity。
By this time; other well…known London printers; Messrs。 Taylor
and Woodfall; had joined Koenig and Bensley in their partnership
for the manufacture and sale of printing machines。 The idea
which now occurred to Koenig was; to employ a cylinder instead of
a flat Platen machine; for taking the impressions off the type;
and to place the sheet round the cylinder; thereby making it; as
it were; part of the periphery。 As early as the year 1790; one
William Nicholson had taken out a patent for a machine for
printing 〃on paper; linen; cotton; woollen; and other articles;〃
by means of 〃blocks; forms; types; plates; and originals;〃 which
were to be 〃firmly imposed upon a cylindrical surface in the same
manner as common letter is imposed upon a flat stone。〃'3' From
the mention of 〃colouring cylinder;〃 and 〃paper…hangings;
floor…cloths; cottons; linens; woollens; leather; skin; and every
other flexible material;〃 mentioned in the specification; it
would appear as if Nicholson's invention were adapted for
calico…printing and paper…hangings; as well as for the printing
of books。 But it was never used for any of these purposes。 It
contained merely the register of an idea; and that was all。 It
was left for Adam Parkinson; of Manchester; to invent and make
practical use of the cylinder printing machine for calico in the
year 1805; and this was still further advanced by the invention
of James Thompson; of Clitheroe; in 1813; while it was left for
Frederick Koenig to invent and carry into practical operation the
cylinder printing press for newspapers。
After some promising experiments; the plans for a new machine on
the cylindrical principle were proceeded with。 Koenig admitted
throughout the great benefit he derived from the assistance of
his friend Bauer。 〃By the judgment and precision;〃 he said;
〃with which he executed my plans; he greatly contributed to my
success。〃 A patent was taken out on October 30th; 1811; and the
new machine was completed in December; 1812。 The first sheets
ever printed with an entirely cylindrical press; were sheets G
and X of Clarkson's 'Life of Penn。' The papers of the Protestant
Union were also printed with it in February and March; 1813。 Mr。
Koenig; in his account of the invention; says that 〃sheet M of
Acton's 'Hortus Kewensis;' vol。 v。; will show the progress of
improvement in the use of the invention。 Altogether; there are
about 160;000 sheets now in the hands of the public; printed with
this machine; which; with the aid of two hands; takes off 800
impressions in the hour〃'4'
Koenig took out a further patent on July 23rd; 1813; and a fourth
(the last) on the 14th of March; 1814。 The contrivance of these
various arrangements cost the inventor many anxious days and
nights of study and labour。 But he saw before him only the end
he wished to compass; and thought but little of himself and his
toils。 It may be mentioned that the principal feature of the
invention was the printing cylinder in the centre of the machine;
by which the impression was taken from the types; instead of by
flat plates as in the first arrangement。 The forme was fixed in
a cast…iron plate which was carried to and fro on a table; being
received at either end by strong spiral springs。 A double
machine; on the same principle;the forme alternately passing
under and giving an impression at one of two cylinders at either
end of the press;was also included in the patent of 1811。
How diligently Koenig continued to elaborate the details of his
invention will be obvious from the two last patents which he took
out; in 1813 and 1814。 In the first he introduced an important
improvement in the inking arrangement; and a contrivance for
holding and carrying on the sheet; keeping it close to the
printing cylinder by means of endless tapes; while in the second;
he added the following new expedients: a feeder; consisting of an
endless web;an improved arrangement of the endless tapes by
inner as well as outer friskets;an improvement of the register
(that is; one page falling exactly on the back of another); by
which greater accuracy of impression was also secured; and
finally; an arrangement by which the sheet was thrown out of the
machine; printed by the revolving cylinder on both sides。
The partners in Koenig's Patents had established a manufactory in
Whitecross Street for the production of the new machines。 The
workmen employed were sworn to secrecy。 They entered into an
agreement by which they were liable to forfeit 100L。 if they
communicated to others the secret of the machines; either by
drawings or description; or if they told by whom or for whom they
were constructed。 This was to avoid the hostility of the
pressmen; who; having heard of the new invention; were up in arms
against it; as likely to deprive them of their employment。 And
yet; as stated by Johnson in his 'Typographia;' the manual labour
of the men who worked at the hand press; was so severe and
exhausting; 〃that the stoutest constitutions fell a sacrifice to
it in a few years。〃 The number of sheets that could be thrown off
was also extremely limited。
With the improved press; perfected by Earl Stanhope; about 250
impressions could be taken; or l25 sheets printed on both sides
in an hour。 Although a greater number was produced in newspaper
printing offices by excessive labour; yet it was necessary to
have duplicate presses; and to set up duplicate forms of type; to
carry on such extra work; and still the production of copies was
quite inadequate to satisfy the rapidly increasing demand for
newspapers。 The time was therefore evidently ripe for the
adoption of such a machine as that of Koenig。 Attempts had been
made by many inventors; but every one of them had failed。
Printers generally regarded the steam…press as altogether
chimerical。
Such was the condition of affairs when Ko
