II.—VALVE-GEAR. Figs. 8, 9, 10 and 11 represent the form of valve-gear used onthe locomotives built by the C. W. Hunt Company for their. HUNTS LOCOMOTIVE VALVE GEAR. narrow-gauge roads, which were described in the November,1889, number of the Journal. This valve-gear is the invention Vol. LXIV, No. 6.] ENGINEERING JOURNAL. 273 of Mr. Hunt, and has been patented by him, and is described inhis specifications as follows : I make use of a connecting-rod in the form of a bent lever,the short arm of which gives a rocking motion through a linkto a rocker pivoted upon a swinging radius-arm. and the valvereceives its motion from a swinging link and block movingwithin a slotted sector. The special feature of the improvement relates to the com-bination, with the parts before mentioned, of an eccentric pivotbetween the swinging link and the radius-arm, ivhereby the ra-dius-arm in its movement varies the position of the pivot of theswinging link sufficiently to produce the lap and lead requiredof the valve in the engine.
