Wheel Barometer


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.
