PRESSURE RECORDING GAUGE.
This device is an ingenious mechanism actuated by clock work and the varying pressures of steam formed within the boiler; it records the time and the pressure upon a revolving roll of paper and preserves an accurate account of the varying conditions which have existed within the boiler.

The advantages derived from its use may be thus summarized: 1, It is a monitor constantly teaching the fireman to be careful to maintain an equal pressure of steam. 2, This uniform steam made possible by the use of the gauge is productive of the greatest possible economy. 3, The even strain maintained insures a long life to the boiler and a minimum of repairs. 4, It is the vindication of an attentive and careful fireman and allows him due credit for his skill and faithfulness, which is too often ill appreciated for lack of a reliable record.
Although described as a boiler room fixture, where it is frequently found in position, the proper place for this admirable device is in the steam user’s office, thus establishing a nerve connection, between engineer and owner, relating to the safety and economy of the power-plant to their mutual great advantage.
