The invention relatesto improvements-in rotary engines; a V l The object of the present invention is to improve the constructionof rotary enginesdesigned fortheuseof steam or. other fluid pressure and-equipped with means for inof the-rotary piston without;the-friction; which; would ordinarily result from such a troducing, the fluid pressure into-theengine central-1y of the rotaryvpiston and of discharging the said pressure at; the per phery discharge. I a 7 With these and'oth'e'r objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in theaccompanying drawings and pointed out inthe claims hereto appended; it being understood that various changes in; the form, proportion,

The number of the outlets may be varied and they may be'arranged at the desiredpoint around the periphery of the outer casing and they can, by the fastening means employed, be set as close together or as far apart as desired,
suitable perforations being provided for the ranged sides of the outlets and isdirected by the same into the annular CllCUHlfQl811- tial space'between the outlets and the rim of the-casing so that the steam will not be deflected back against the rotary piston and interfere with the free-rotary movement of the same. The friction incident to such back action or contact of the steam with the ro-- tary piston is therebyeliminated. The sectional formation of the outer casing affords ready access to the interior of the engine and will enable the parts to be readily assembled and separated for renewing the packing or any other purpose.
vThat-is claimed is:
1; A rotary engine of the class described including a casing,- a rotary piston having a a central inletchamber and provided with a spiral passage extending fromthe inlet chamber to the peripheryof the rotary piston, said rotary piston being arranged within the casing and the latter being extended beyond the periphery of the rotary piston and having an exhaust port, and a pluralityof arcuate outlets consisting of radially arranged side and curved connecting ends'and extending across the casing beyond the rotary piston and arranged in spaced relation with the rim of the casing to provide an outer"annular space, theradially arranged sides of the-outlets being adapted to deflect the steam or other fluid pressure into the circumferential space and relieve the rotary piston of friction. I
2. A rotary engine of the class described including a casing, a rotary piston having a central inlet chamber and provided with a spiral passage extending from the inlet chamber to the periphery of the rotary pis- Gopies of this patent may be obtained for ton, said rotary piston being arranged within the casing and the latter being extended 7 beyond the periphery of the rotary piston and having an exhaust port, a plurality of arcuate outlets consisting of radially arranged side and curved connecting ends and extei'idingacross the casing beyond the rotary piston and arranged in spaced relation with the rim of the casing to provide an outer annular space, the radially arranged:
sides of the outlets being adapted to deflect the steam or other fluid pressure into the circumferential space and relieve the rotary piston of friction, and fastening de vice piercing the casing atopposite sides thereof and extending into openings in the arcuate connecting ends of the outlets and detachably secured to the same within the casing. a
3. A rotary engine of the class described" including spaced standards provided with bearings and having annular flanges thereat;
a stationary casing composed of circular sections secured together at their peripheries and provided with central tubular exten-'- sions having'annular flanges secured'tothe flanges of thestandards, a rotary piston arranged within the casing and having a cen-- tral inlet chamber and aspiral or convolute passage or channel extending from the'-central chamber to theperiphery of the piston,
said piston being also provided at opposite sides with recesses, solid and hollow shafts having heads secured inthe saidrecesses,"
said shafts being mounted inthe bearings and a hollowshaft being extended beyond" the bearing at the outer side thereof and communicating'at its inner end with the central-chamber, fastening means for securing the flanges of the casing to the flanges of the standards, a coupling member se-- cured to one of the standards and receiving the projecting end of the hollow shaft and" provided with packing, and separate outlets mounted within the casing at the outer por-' tion thereof and presenting deflecting'faces to the channel of a rotary piston,
