Description (Brief)
This patent model demonstrates an invention for a sheet-feed apparatus which was granted patent number 21591. The patent details a sheet-feeding apparatus, operating independent of the printing machine, with improved registration.
William Bullock (1813-1867) made himself a name in 1852 with a hand-cranked wooden press to which a self-feeder was attached. He followed this with other fast presses, focusing on the problems of feeding. This led him to his most famous press, the web perfecting press (Patent 38200). In 1867 Bullock was caught in a press he was installing for the Philadelphia Public Ledger, and died from the injuries.
