Patent Model for Bed-and-Platen Printing Press

Patent Model for Bed-and-Platen Printing Press

<< >>
Description (Brief)
This patent model demonstrates an invention for a double bed-and-platen power press with a frisket at each end and is considered an unnumbered patent. The bed was raised by toggles beneath against the fixed platen. This patent provided the basis for the single-ended Adams Power Press, a well-loved iron machine later produced by R. Hoe & Co. In the 1870s it was still considered to produce finer letterpress work than any other machine on the market. It was pre-eminently a book press. Isaac Adams (1803-1883), with no schooling but ample inventive genius, introduced his power press at the age of 25 and derived his living from its success.
