The Wonder Book of Knowledge: The Marvels of Modern Industry and Invention, the Interesting Stories of Common Things, the Mysterious Processes of Nature Simply Explained
Industrial arts -- History
Among the marvels of machinery of the present day there are none more
complicated and bewildering in appearance than that by which the news of
the world is sent adrift within the daily newspaper and none more
marvelously effective in its operation. If we go back to the days when
the seeds of the modern press were planted, we find them in the
hand-printing done by the Chinese with their engraved blocks, and with
the simple press used by Gutenberg about 1450, when he printed the first
book from movable types.
His press consisted of two upright timbers held together by cross pieces
at top and bottom. The flat bed on which the types rested was held up by
other cross timbers, while through another passed a wooden screw, by the
aid of which the wooden “platen” was forced down upon the types. The
“form” of type was inked by a ball of leather stuffed with wool, the
printer then spread the paper over it, laying a piece of blanket upon
the paper to soften the impression, after which the screw forced the
platen down on the paper and this on the type. This press was not
original, since similar cheese and linen presses were then in use.

For 150 years this crude method of printing continued in operation, the
first known improvement being made by an Amsterdam printer about 1620,
he adding a few parts to render the work more effective. Such was the
simple press still employed when Benjamin Franklin began his work as a
printer a century later. In 1798 the Earl of Stanhope had a cast-iron
frame made to replace the wooden one and added levers to give more power
to the pressman. Woodcuts were then being printed and needed a stronger
press.
We must go on with the old Gutenberg method and its tardy improvements,
for another century, or until about 1816, when George Clymer, a printer
of Philadelphia, did away with the screw and employed a long and heavy
cast-iron lever, by the aid of which the platen was forced down upon the
type, the operation being assisted by accompanying devices.
As will be seen, the growth of improvements had until then been very
slow. From this time forward it became far more rapid, some useful
addition to the press being made at frequent intervals. The “Washington”
press, used at this time by R. H. Hoe & Co., of New York, embodied these
improvements, and became one of the best hand-printing presses so far
made. The first steam-power press was introduced by Daniel Treadwell, of
Boston, in 1822, the bed and platen, or its successor, the cylinder,
being used in these and in the improved forms that followed until after
the middle of the century.
