Wheel Barometer

Wheel Barometer

Usage conditions apply
Invented in the 1660s by Robert Hooke, the "curator of experiments" in the new Royal Society of London, the “wheel” or “banjo” barometer has a tube that is bent into a J shape; a float, sitting on the shorter end of the tube, connects with a circular scale that is large and easily read. Barometers of this sort have long been popular for domestic use. This example is marked “D. Fagioli & Son, 39 Warner St Clerkenwell” and was made in London, perhaps in the 1840s. The dial reads from 28 to 31 inches of mercury. In addition to the barometer itself, there is a twisted gut hygrometer, a spirit thermometer, and a convex mirror. The Taylor Instrument companies gave it to the Smithsonian in 1923.
