Slot Machine Patents (by date)

Patents are invaluable for research and restoration, recording in detail innovative and successful designs and others which never went into production, or of which no examples survive. British patents for non-British machines and some foreign and non-coin-operated (but related) devices are included. If you know of others, please add them. Many from 1890 onwards are online at Espacenet.
