Abstract

209,290. Simmonds, S. Dec. 29, 1922. Thermometers.-A thermometer, particularly for use in incubators, is mounted on a scalemarked plate of light-transmitting material adapted to be illuminated by suitable means. The thermometer a is mounted on the translucent plate b, which may be recessed a receive the bulb, so that the stem of the thermometer lies close to the plate In rear of the plate b is a reflector c carrying a lamp d for illuminating the plate. The plate and reflector are preferably wedge-shaped as shown, and the reflector may also be tapered off so as to approach the plate at one end.
