Description
This is a brass instrument, 5¼ inches diameter and 2½ inches deep. The inscriptions on the metal face read “Stormoguide” and “COMPENSATED FOR TEMPERATURE” and “Tycos” and “UNITED STATES COPYRIGHT 1922 TAYLOR INSTRUMENT COMPANIES, ROCHESTER, N.Y.” The pressure scale around the circumference reads from 27.5 to 31.5 inches of mercury, in fifths of an inch. Letters around the scale, running from A to K, correlate with various weather conditions.
An altitude scale on the back of the instrument extends from 0 to 3500 feet, and reads: “ROTATE THIS PLATE UNTIL THE ARROW ON THE CASE POINTS TO THE ALTITUDE OF YOUR LOCALITY PATENTED AUGUST 18-1914”
The Stormoguide was based on a design developed by Francis E. Collinson of London, England. It was widely promoted for domestic and amateur use.
The Taylor Instrument Companies began operating, as such, 1904, and introduced the Tycos trade mark in 1908. It obtained a copyright on the term Stormoguide in 1922, and advertised it as a simplified barometer that indicated weather probabilities for 12 to 24 hours in advance. It gave this example to the Smithsonian in 1923.

Comments

Using the rotating plate, you can adjust for the altitude for your locality... but how do you reset the correct air pressure at the time you adjust for altitude? You can't recalibrate one without adjusting the other.

" I have the Taylor corporate seal (1907) and the meeting minutes of the day of incorporation in a leather bound book. My grandmother, Millicent Taylor was at one time the largest stockholder on record, as listed in the book. I have various Taylor items in my home, none of which are of great value. It's nice to see the Taylor name once in a while. Good luck."
