Longitudinal section, showing ball bear-ing, overlap of the jaws, wedges, and volutecap. 202. Shows the alternate jaws, wedges, andthe volute cap for tightening the wedges. 203. NOVEL VALVE GEAR. The crank-pin arm is pivoted to the lever R at E, and tothe link block B, and also to the valve rod asshown. The motion of the valve is controlledand reversed by rocking the link L. STEAM POWER APPLIANCES. 93. 204. REVERSING GEAR without eccen-trics. The valve stem is connected to the middleof a short link, 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 incHned link or reversing barand having suitable shoes for taking up block receives motion from a somewhatsimilar block, which slides 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
