Printing 1100 Sheets per Hour (July 23, 1813 – November 29, 1814)

On November 29, 1814 The Times of London newspaper published its first issue printed on a double steam-driven Koenig cylinder press.

The output of the new machine was initially 1,100 sheets an hour—more than four times higher than the manually operated press previously used by the newspaper.

Koenig's third British patent, no. 3725, for "Certain Additional Improvements in my Method of Printing by Means of Machinery," issued on July 23, 1813

"contained improvements on that of 1811 and served as the basis of the double machine. For this a second cylinder was added by which the return movment of the bed was made productive. While the printer cylinders were divided into three parts as before, each being covered with cloth with points attached, the 'friskets' were abolished in favour of endless tapes conducted over rolls. The ink system underwent modifcation to the demands of double printing. The inking rollers were set transversely across the forme with their axles meeting on one side. In the patent the inking rollers were still described as covered in skin, but Koenig learned of the superiority of composition rollers during the year, otherwise The Times machine could not have worked as effectively as it did" (Moran, Printing Presses, History and Development [1973] 107).
