Timby’s Victorian Antique Stick Barometer pat. 1857 38 1/2″ long, 2 7/8″ wide, 1 5/8 thick. There is no mercury in the glass tube or the one intact bulb (one is missing). Front glass and printed label are intact; glass tube is intact and visible from front glass; there are two missing screws on the back; the front rosewood is in very good condition and displays very nicely. Here’s a little background I found on the web about the Timby barometer. The first of his two barometer patents, issued in 1857, described an instrument in which the expansion of mercury with increase of temperature would not burst the tube. Scientific American praised Timby for having succeeded in rendering this instrument perfectly portable, going to predict a speedy and universal adoption, especially among agriculturists, they more than any other class (save the mariners), need the counsel of this faithful monitor which leaves nothing to conjecture, but tells with promptness of the coming storm long before a threatening is visible in the sky. This example is marked TIMBYS PATENT, Nov. 3rd 1857 as well as The fall of the mercury indicates a STORM. The rise of the mercury indicates fair WEATHER. Patent 18,560 (1857).
