STEAM POWER APPLIANCES. 93. 204. REVERSING GEAR without eccen-trics. The valve stem is connected to the middleof a short Hnk, one end of which is pivoted to thecrosshead bar, and the opposite end to the radialbar, which in turn is pivoted to the link latter member consists of a block of irongrooved to fit the inclined link or reversing barand having suitable shoes for taking up block receives motion from a somewhatsimilar block, which shdes on the connecting rod;the block being held in the proper horizontalposition by means of a radial rod pivoted to itand to the cylinder. The crosshead bar passesthrough a sleeve block carried by the crosshead,which is fitted with shoes to take up wear. Itwill be seen that the crosshead bar imparts a hori-zontal movement to the valve stem, which move-ment is equal to the lap and lead of the valve. 205. FLOATING VALVE GEAR or reversing ram for marineengines. The floating lever g is here connected to the crosshead at k. The rod / is hinged at /i tothe floating
