Abstract

10,173. Dittmar, W. O. May 1. Thermometers.-The spiral metal strip a of a bimetallic thermometer is insulated to minimize lag. One end of the strip a is secured to a pillar c, the other end being secured to the pivot b carrying a pointer g. T h e plates e, d and pillars c, f are formed of heat-insulating material such as vulcanite, fibre, &c. The enclosing casing consists of a bezel i attached to the backing hand fitted with a glass front. The capsule j to which the plate d is secured is preferably constructed of heat-insulating material perforated to allow free excess of air, but it may also be made of metal with its inner surface whitened br polished. The backing or scale part h and the bezel i may a so be perforated. In a modified form of apparatus, the plate e is secured to the scale plate. In the Provisional Specification, it is stated that a ring concentric with the final strip and supported on the insulated backing is used, the ring carrying a suitable support from its circumfererence for the axis of the indicating-pointer.
