Spirometer, Long Life, Spirometer Company of California, 1921

From “Youth obtaind and retaind” by George Starr White, Phillips Printing Company, 1921, Page 34.  The spirometer was developed by Charles E. Ramage

“This littl instrument is “a western product” devized by a westerner seeking for helth, which he found, and is manufactured by the Spiro-Meter Co. (Inc.) of Pomona, California.  These peopl ar wel named “helth promoters.”  Probably their littl “lung watcher” is doing more to interest peopl in the development of their breathing than any other instrument.  This littl instrument is only the size of a watch and can be carrid like a watch attacht to a chain or cord like a watch. One can set the hand bu the stem setter, and many times a day watch just how much air he can expel from his lungs. Then as I hav said before, the reflex causes a greater amount of air to be drawn back into the lungs.”

{FYI, the misspellings appear to be deliberate as this is how the author spelled words throughout the book.}

Spirometer, Stoelting, circa 1920


A Hutchinson-style spirometer from Stoelting, a manufacturer and distributor of school supplies.  Identical, except for the nameplate, to spirometers manufactured by the Naragansett Machine Company of RI between 1900 and 1920, Stoelting sold these spirometers from around 1920 to 1940.  At guess, this one is from around 1920. Found on the Dr. Nicholas and Dorothy Cummings Center for the History of Psychology website.
