ORIGINAL (Stamped) RECEIVED (Stamped) JUL 21 1920 4 X.3903 X.367 X.3678 RE FOXBOROUGH THERMOMETER. We have received from America one Foxborough Thermometer. This instrument is very similar to the Cambridge instrument which we are using as standard on our cars. The chief difference is that the scale is in fahrenheit instead of centigrade. We have had the instrument working on a car for about 5000 miles. It has given no trouble. The position of the flange on this instrument should be altered so that it comes in line with the U.S. pressure gauges. In its present form it would be a difficult instrument to fit flush into the Instrument Board. The scale on the Instrument is in silvered letters. The needle has a rather nasty finish of white paint. It has been decided that when we use the Thermostat Control for Water Temperature, the Thermometer is unnecessary. Mr. Olley in his memo. of the 1st.inst. considers that even with a Thermostat the Thermometer is necessary. We are not altogether convinced that this is so. We are certain that for the conditions in England that when the Thermostat is fitted the Thermometer is not necessary because the temperature recorded by the Thermometer remains constant under all conditions. In fact, we think fixing a Thermometer may cause customers not to take proper precautions against the radiator freezing up in Contd. | ||
