Hand printing press
Ruggles, Stephen P. · ca 1859
This patent model demonstrates an invention for a lever press using a combination of course and fine screws, the first to lower the platen fast, and the second to produce greater power at the end of the pull. It also included inclined ways or tracks, so the bed was raised as it was drawn under the platen. The invention was granted patent number 23951.
