Draper Recording Thermometer

<< >>
Daniel Draper, director of the meteorological observatory in Central Park, established the Draper Manufacturing Co. in the mid-1880s and began producing self-recording meteorological instruments. This example is marked "DRAPER'S SELF-RECORDING THERMOMETER 152 FRONT ST. N.Y. CITY PATENTED 1887." It is a bimetallic instrument with a flat chart (missing) that revolves once a week. The Lick Observatory donated it to the Smithsonian in 1960.
