Fig. 6 valve gear was as elevation draftsman in the building ofthis locomotive and as he has since been closely connectedwith the designing and application of this gear an outline of Company is shown in Fig. 1. This is arranged for insideadmission with the eccentric crank leading the main crankpin and the radius bar in the top of the link in the forwardmotion. With this arrangement the irregular movements dueto angularity of the main rod are compensated by the angu- 744 December, 1921 RAILWAY MECHANICAL ENGINEER 745 larity of the eccentric rod, consequently it will produce thenearest to perfect results as to cutoffs, etc., at all positionsof the reverse lever. The arrangement shown in Fig. 2 is similar to Fig. 1, butthe eccentric follows the main crank, which places the radiusbar in the bottom of the link in forward motion. An arrangement for outside admission, with the eccentricleading and the radius bar in the bottom of the link in for-ward motion is shown in Fig. 3. This, on accoun
