When the gauge shows 100 lbs., it means there is a pressure of 100 lbs. against every square inch of the boiler surface. (Fig. 4.) How Gauge Works The pressure of steam has a tendency to force the spring out of a coil shape to straight. This works the little V-shaped part with fine cogs on the hand, mov- ing the hand to register num- ber of pounds pressure to the square inch of space co

This works the little V-shaped part with fine cogs on the hand, mov- ing the hand to register num- ber of pounds pressure to the square inch of space con- tained in the boiler. As the steam increases in pressure it straightens the spring and drives the hand around to register according to the figures the hand points to on steam Fig. 4. Steam Gauge. How to Test Steam Gauge Use pump, screw up, forcing oil into gauge spring and have a tested gauge in connection so the pounds of pressure indicated on gauges can be compared. To Set Spring When spring becomes weak it can be set by bending down a little.
