Category:Packard motor thermometers

From 1912 until 1928, Packard offered its cars with a plain or decorated radiator filler cap. As there was no gauge to inform the driver about the engine temperature, the motor thermometer became a very popular option, either dealer installed or aftermarket. This device consists of a new cap and a small casing that displays a thermometer behind a glass lens. The casing's base is a screw socket that fits on the cap. There are many different designs, and detail solutions. Most popular was the Boyce MotoMeter, which was also available at the Packard dealership. All radiator-fiited thermometers are readable from the driver's seat, and some also from outside, standing in front of the car. A metal plaque shows the car or truck manufacturer's logo. Further, a handle could be added, and there were decorative items like wings or ornaments. In Packard's case it was often the "goddess of speed" winged lady. These items fit neatly between the cap and the thermometer when the ladder is screwed on.
