Directions for adjusting these patent delay dash-pots should be secured, if necessary, from the buildersof each particular engine. Operators often request information of the buildersin reference to their left-hand or right-hand builders need some information from the opera-tors before giving full instructions, and Figs. 21 and 22show a cut of the data sheets they desire to have filledout. A study of these will enable the operator togive the data desired without first sending to the shopsfor such sheets. 90 SHAFT GOVERNORS. FIG. 21 Speed. . .Revs, with no Weight-Arm.
