This invention relates to certain improvements in gages used on machines for indicating either the pressure or vacuum. One object of my invention is to construct the gage so that the predetermined pressure, which the machine is supposed to carry under normal conditions, will be indicated at the top of the gage and when the machine is working under correct conditions the pointer, or hand, will be in the vertical position. By this construction an operator can ascertain at a glance whether or not the machine is running under proper pressure without having to read the numerals on the gage. Where there are a number of machines running under different pressures an operator, or overseer, can readily discern, when at a distance, whether the machines are carrying the proper pressure. A further object of the invention is to illuminate the pointer and, in some instances, the marks on the dial, by using a luminous coating so that the pointer can be seen in the dark, as, in a number of cases, the pressure gages are located in places inaccessible to the daylight.
