Period

1930's

Canada

The 3 cup anemometer was designed by Canadian meteorologist John Patterson of the Canadian meteorological service in the 1920's; this example & successive versions were used by the Canadian service for decades.

Function

An instrument that measures wind speed & direction by means of a cupwheel & wind vane respectively, with the readings recorded by a separate anemograph.

Technical

Patterson showed that the 3 cup wheel was superior to the Robinson 4 cup wheel used previously which it supplanted. His anemovane combined a 3 cup wheel & a wind vane on a concentric double shaft. This is an example of the earliest version, used with an anemograph only (e.g. 870866, 870867).
