Recording thermometer, self-registering thermometer, metal / glass / paper, made by Seth Thomas / The Draper Manufacturing Company, New York, United States of America, 1887-1907
A recording thermometer consisting of a clock mechanism (made by Seth Thomas) and a thermometer held inside a metal encasing. A recording chart is placed on the circular dial at the top of the encasing. The dial rotates once a week. A pen mechanism attached to the thermometer records the temperature on the chart. With the recording thermometer is a glass plate sign bearing descriptive text. This sign was originally fixed to the front of the encasing below the dial. However the sign has broken and it is currently stored between two sheets of perspex. Also accompanying the recording thermometer is a circular glass cover that fits over the dial in the metal encasing.
