Maximum and Minimum Thermometers

Description:

Sset of two glass thermometers, each with a grooved aluminum plate marked "H. J. GREEN B'KLYN. N.Y." and "SIGNAL CORPS, U.S. ARMY." One is also marked "No. 41500" and "MAXIMUM" and the other is marked "No. 44505" and "MINIMUM." Each stem has a milk white back. The clear front of the maximum stem is graduated every degree F. from -34 to +128. The clear front of the minimum stem is graduated every degree Fahrenheit from -34 to +112.

The thermometers are held in a Townsend support marked "Julien P. Friez & Sons." This support, which was introduced around 1905, enables the maximum thermometer to be released from its normal horizontal position and whirled rapidly around, and the minimum thermometer to be tilted so that the index can slide down to the end of the spirit column.
