Described in the August 11, 1882 issue of Medical News. “New spirometer: M.G. Bellange has recently constructed an apparatus for the measurement of the capacity of the chest, the amount of air expired in a given time, and the amount of exhaled gases. It consists of a mouthpiece, a spirometer and a carbonimeter.” Taken from: http://www.webimed.net/Spiro_1889.html

“The pupil, after loosening the clothing about the chest and taking a full inspiration, filling the lungs completely, should blow steadily into the spirometer until all the air possible has been expelled from the lungs. Two or three trials may be allowed.”
A recording mercury U-tube manometer. The float in the left side of the U-tube moves up and down in response to respiratory pressures. The thin metal rod attached to the float had a recording pen at its tip.

Purported to be a Hutchinson spirometer in the text of the article, this looks a lot more like a conglomeration of several different designs instead. The manufacturer was not named but was likely German.
