Locomotive appliances . under pressure in the ordinary temperature ofthe factory, or where it takes place, will when the sameare heated in use to a high temperature lengthen byexpansion to such an extent that, when they are sub-jected to the sanre pressure, their free ends will movethrough a larger arc than When they were movement multiplied by the ordinary mechan-ism of a steam gauge for transmitting it, causes thisincreased pressure-to appear upon the dial. In such LOCOMOTIVE APPLIANCES. 97 a heated condition of the tube springs, the error pro-duced is sometimes considerable, being several percent, greater than the true pressure, thus deceivingthe user of steam into the belief that he is getting aless result, in work, from the indicated pressure thanhe ought. This error can be corrected by suitablemechanism in the steam gauge. Such an one, it isclaimed, is internally shown by Figs. 11 and 12. Inthe ordinary steam gauge, the bar which transmitsthe movement of the free ends of its tube springs is.
