Herman Hollerith's "Keyboard punch" used for the 1890 U.S. Census was a pantograph design and sometimes referred to as "The Pantograph Punch".
It was designed during the late 1970s / early 1980s by Brecknell Willis and British Rail Research Division as part of ongoing research into developing a pantograph capable of speeds over the 100 mph (160 km/h) limit of the Stone Faiveley AMBR pantograph, which was the standard type fitted at the time.
In 1960, four Ae 4/7 (10948–10951) got a wider pantograph compatible to ÖBB standards, so that they could run international trains from St. Margrethen via Bregenz to Lindau.
