How lever-action voting machines really worked

Over the years I have written many articles about direct-recording electronic (DRE) voting machines, precinct-count optical-scan (PCOS) voting machines, ballot-marking devices (BMDs), and other 21st-century voting technology. But I haven’t written much about 20th-century lever machines; these machines were banned by the U.S. Congress in the Help America Vote Act and have not been used since 2012.

Recently, upon a midnight dreary, while I pondered, weak and weary, over many a quaint and curious volume of forgotten technology, I came across the excellent 1993 book, The Way Things Really Work, by Henry Beard and Rod Barrett. This book has a clear explanation of the inner workings of mechanical lever voting machines, as follows.

I think it should now be clear why Congress banned this technology.

The book also has explanations of “How candy machines eat your quarters,” “How airlines lose your luggage,” “How elevators know to close their doors when you come running,” and so on.
