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]
