This patent model demonstrates an invention for a rotary printing press; it was granted patent number 9987. The press had several impression cylinders and inking stations arranged around a large type cylinder. A web of paper was moistened and folded concertina-fashion for feeding. It was printed at the first series of impression cylinders and refolded. Then it was turned, and printed on the other side at the next series. Finally, it was cut into sheets. According to Stephen D. Tucker’s <I>History of R. Hoe & Company</I>, this patent was bought by R. Hoe & Co., probably more to keep it out of the market than with a mind to its development.
