(4.) In rotary engines of the class set forth, a detachable outer casing, divided centrally, and a disc whose side-surfaces are in contact with the grooved edges of jointing-rings, the whole combined to form an annular piston-chamber, as described and shown, and for the purposes set forth. (5.) In rotary engines of the class set forth, the combination with an annular chamber as claimed in Claim 4 of one or more steam-admission chambers having a central slide-passage and associated steam-passages communicating with a valve-chamber having inlet-ports arranged for the simultaneous inflow and exit of the steam into the said annular chamber, as described and shown, and for the purposes set forth. (6.) In rotary engines of the class set forth, the combination with an annular chamber of the kind described of a radial slide, with steam-cavities formed therein, and a central slide-block made adjustable and operated in the manner described, as described and shown, and for the purposes set forth.
