Chart #5; Old Regulation - White Motor Company White Steamer M Service Manual

From the time of building the first cars up to year of Naught Seven the regulation remained exactly the same
in principle. This principle was entirely different from the one in use at the present time. The thermostat regulated the
amount of fuel fed to the burner by closing off the supply when the temperature reached a predetermined degree. The
water regulator controlled the amount of water fed to the generator by opening and closing at a predetermined
pressure. Suppose a case, where the fuel is turned on to the burner and the fire is burning. There is enough excess fuel
to cause the temperature in the generator to rise. When the temperature reaches three hundred and ninety degrees the
thermostat closes shutting off the supply of fuel. Without any fire below the coils in the generator the steam pressure
immediately begins to drop back, As soon as it drops to the point where the water regulator closes the water starts to
the generator, causing that already contained therein to begin to move downward through the coils, being forced to do
so by the action of the pumps. This movement of the water causes the temperature of the steam to drop a slight
amount, just enough, however, to cause the element in the thermostat to contract sufficiently to turn on the fuel again.
