QuoteThe press was named after Thomas Main, a printer who took out a patent for his Main or Tumbler machine in 1850. The peculiarity of the Main consisted of the rocking action of the cylinder which lifted slightly and rolled backwards or 'tumbled' back to the starting position after the impression stroke. It was claimed this action enabled the printed sheets to be delivered more efficiently! He joined with William Conisbee in 1854 but apparently got into financial difficulties shortly thereafter and fled to Australia. (where else!) Conisbee, undeterred, bought out the patent, improved the machine and in 10 years sold some 700 models (unsure whether he continued with the Tumbler principle on later models?).
