The Blaew Press, 1620
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.

The idea of replacing the platen by a cylinder was not a new one. It was employed in printing copper-plate engravings in the fifteenth century, a stationary wooden roller being employed, beneath which the bed, with its form and paper, was moved backward and forward, a sheet being printed at each movement. With this idea began a new era in the evolution of the printing press. A vast number of patents have since been issued for printing machines in which the cylinder is connected with the bed and later for the operation of two cylinders together, one holding the form of type and the other making the impression. But all these were for improvements, the underlying principle remaining the same. The conception of a press of this character in which the paper was to be fed into the press in an endless roll or “web” goes back to the beginning of the nineteenth century, though it was not made available until a later date.
Meanwhile, however, patent after patent for the improvement of the cylinder press were taken out and the art of printing improved rapidly, the firm of Hoe & Co. being one of the most active engaged in this business, the United States continuing in advance of Europe in the development of the art. The single small cylinder and double small cylinder introduced by this firm proved highly efficient, the output of the former reaching 2,000 impressions per hour, while the double type, used where more rapid work was needed, yielded 4,000 per hour.

But the demands of the newspaper world steadily grew and in 1846 a press known as the Hoe Type Revolving Machine was completed and placed in the office of the Public Ledger, of Philadelphia. By increasing the number of cylinders the product was rapidly added to, each cylinder printing on one side 2,000 sheets per hour.
