Fig. 101 is athree-way cock for attach-ing the indicator to thecylinder. Reducing the only practi-cally universal mechanismfor reducingthe motion of the crosshead is the reducing wheel, 2>device in which, by the employment ofgears and pulleys of different diameters,the motion is reduced to within the com-pass of the drum, and the device isapplicable to almost any make of engine,whether of high or low speed. Somemakers of indicators attach the reducingwheel directly to the indicator, thus pro-ducing a neat and very convenient ar-rangement.
