Vertical section, showing details of the parts. 253. ROTARY STEAM ENGINE. A cylindrical piston A,with wing abutments C, C, A double cam block H, made adjustable by a set screw and with exhaust ports at Kand I. A steam port through the cylindercover and a curved passage in the cover shownby the dotted lines, so that the abutment pis-tons take the full steam pressure through thesector passage, from F to G, and expandingthrough about one-quarter of a revolution of3 the 254. ROTARY ENGINE. Recesses are formed in tne pistonhaving an S-shaped partition between them, the recesses opening at opposite ends of the piston intothe steam chests, and by means ofports into an annular space be-tween the casing and piston. Thepiston has an eccentric portionwhich has a perfect contact bear-ing with the inner wall of thecasing by means of a yieldingblock in a recess on its periphery,the eccentric also acting alternatelyto press back abutment blocksadapted to slide on antifrictionball bearings in recesses in thearms of the casing. The steamsupply pipe connects with a pas-sage communicating with a circularchamber in which is a rotary valve,by means of which steam may be directed into either of the branchpipes connecting with the steam chests at the ends of the piston, thearrows showing the direction of the steam when admitted int
