Patent Model of a Machine for Printing Paper Hangings
Shaw, William M. · ca 1849
This patent model demonstrates an invention for a block-printing press for wallpaper and oilcloth; the invention was granted patent number 6404. Two sets of blocks, suspended over the paper, were mounted in a frame that moved laterally so that one was re-inked by brushes while the other delivered its impression. The paper traveled along a table transverse to the block frame.
