Antique Boyce Motometer radiator cap hood ornament on display during Classic Auto Show at Fenders` on Front Street annual Father`s Day event in Issaquah, WA near Seattle, WA. The Boyce MotoMeter was patented in 1912, and was used in automobiles to read the temperature of the radiator. From then through the late 1920s, the Boyce MotoMeter Company in Long Island City, New York, manufactured a variety of different models which varied in size and design. The non-pressurized Thermosiphon cooling systems that were widely used until the 1920s led to a low boiling point. The Boyce MotoMeter was a simple device. Although it not always warned about engine overheating in time to prevent damage, it offered for the first time information about the engine temperature from the driver`s seat.
