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.
