Context

Country: Canada
State/Province: Unknown
Period: mid 1940s to early 1950s
Canada: This hub represents a stage in the development of anemometers designed and used by the Meteorological Service of Canada. A piece of meteorological equipment from a large collection of meteorological instruments used by the Meteorological Service of Canada (previously Atmospheric Environment Service) and acquired by the CSTM since 1967. MSC is the government agency responsible for collecting and disseminating meteorological data and forecasts in Canada. It was founded in 1871 in Toronto where it is still headquartered. The MSC was originally on the University of Toronto downtown campus but moved to Downsview in 1971 on land owned by UofT. The headquarters houses laboratories, research facilities and calibration and instrument maintenance facilities (now largely contracted out).
Function: A prototype for an anemometer hub, the central point to which the anemometer cupwheel arms are attached. An anemometer is an instrument used to measure wind speed.
Technical: Between 1946 and 1951, the Meteorological Service of Canada changed from machined hubs and tubular supports for anemometer cupwheels to single hub and support casting. This hub is a prototype from the later stage of this development. Three identical cast arms are attached to the hub. The anemometer cups attached to the arms.
