of the casing of the engine, so as to overcome the friction which would otherwise be caused., and also to permit ready escape of steam from the spaces between the teeth soon as the latter pass beyond the limits of the port rings 14 or 15 which may be in action, the er;- haust steam finally escaping from the casing through an exhaust port or passage 26, (see Figs. 1 and 2.)
By reason. oi the use of a pair of internally toothed rings 6, one on each side of the oentral disk 5, in co'" @rations/ith a or' similarly disposed "1rd inter-meshing toothed wheels 7, the pressure upon the shaft 4' is equalized and uneven Wear oi' said shaft prevented, the pressure oi' the opposite port rings 14 or '15, being also halanced, and having no tendency tocause uneven side pressure upon the dish 5. By utilizing the rings 6 as the power-transmitting memhers the engine, the speed of rotation oi" the shaft is reduced as compared with an engine in which the wheel 7 is the transmitting member, this being an element of advantage in an engine ,of this type, as it reduces the speed oi the rotating power shaft 4 While correspondingly increasing the power of the same.
In that form of my improved engine, shown in Fig. 6, a plurality oi toothed Wheels 7'L are employed in connection with the internally toothed ring 6, and port rings 14 and 15 are i. employed at the points Where each oi' the Wheels '7a is in mesh With said ring 6, the steam supply pipes and reversing valves being likewise multiplied in order to provide for the application of power to the ring 6 at ditferent points throughout the toothed portion of the same. In this engine the reversing racks 173 are carried by segments 2()a adapted to bearings in radial brackets 2E? on the engine casing, and said reeks are operated by means of a lever 22a hung to one rci said brackets and connected to oneof the segmental rods 20 by means ot lint; I claim:-
1. A rotary engine in which are combined. al casing, a poivrer-'shaft having a dish with internally toothed ring thereon, a. toothed Wheel meshing with said ring and mounted eccentrically in respect to the axis of the same, and means for introdufine t c i "v iluid between tiy ,Y While said teeth are in mesh. v
2. A rotary engine in if'fhich are combined a casing, a power shaft having a dish with internally toothed rings disposed one on each side of the same, toothed Wheels meshing Withsaid internally toothed rings and mounted eccentrica-ily in respect to the axisoi the same, and means for nltrcdueing the motive l'luid between said toothed members Where internally toothed ring thereon toothed Wheel meshing with said internally toothed ring and mounted eccentrically in respect to the axis of the same, two motive fluid inlets, one on each side of aline drawn from the axis of the toothed ring midway throng-inthe int rmeshing portions of the ring and Wheel, and a reversing valve for directing the niotive liuid to either of said inlets.
' 4. 'The combination, in a rota'ryengine, of a sing having a valve chest thereon, a poe r shatt having a disk with internally toothed ring, toothed Wheel meshing with said ring and mounted eccentrically in reto the asis oi the saine, said ring and Wheel being free from side contact With the easing, and a port ring having side contact with s id wheel. and ring Where their teeth are in mesh with 'one another.
lhe combination, in a rotary engine, oi a casing having a valve chest thereon, a snait having a disk with internally toothed ring, a toothed wheel m-shing with said ring and mounted eccentrically in respect to the axis ci the same, said Wheel and ring being tree from side contact with the casing, a port ring having side Contact with said Wheel and ring Where the teeth of the same are in mesh with one another, a bridge on said port ring, and a set screw bearing upon said bridge and serving to maintain the port ring in contact with the rotating 'toothed members oi the engine.
