To all whom t nfl/wy concern: l

Be it known that I, AMARIAH W. JACKSON, a citizen of the United States, residing at 315 East Sixty-third street, in the city of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Steam Turbine-Engines, of which the following is a specification.

My invention relates to that class of engines known as steam-turbines.

The object of my invention is to produce a simple and cheaply-constructed engine in which by the fullest application of the principle of deflection to secure the largest percentage of the initial and expansive force of the steam entering the engine and convert it into motion ;A that While constructed of but two parts will be automatic in action.

The manner in which I accomplish my object is set forth in the following specification and illustrated in the accompanying drawings, in which-- Figure 1 is a central vertical section on the line 1 1, Fig. 9. y Fig. 2 is a central vertical section on line 1 1, Fig. 9, showing the construction of the main supporting fixed half of the engine. Fig. 3 is a vertical sectional view on the line 1 1, Fig. 9, showing the construction of the supportedrotatableart of the engine. Fig. 4 is a vertical centraIcrosssectional view on the line 6 6, Fig. 8, showing the construction of the main supporting fixed half of engine. Fig. 5 is a vertical central cross-sectional view on the line 6 6, Fig. 8, showing the construction of the supported rotatable half of the engine. Fig. 6 is a central vertical cross-sectional view on the line 6 6, Fig. 8, showingboth halves of the engine in the operating position.

etail sec-tional view of one of the steamorts, showing the corrugated faces therein. ig. 8 is a sideview of the engine, and Fig. 9 is a front view of the engine.

` In the drawings, A indicates the main stationary half of the engine, cylindrical `in form, rovided with a base A. One side A2 of t is forms an integral part of this half i and has a central aperture A3, into which a steam-supply pipe A4 is attached. This aperture opens into a steam-chamber A5. Extending through the wall of this chamber is a series of steam-ports B. The direction of these ports is tangential to the axis of the chamber and engine. The external face A of the wall of this steam-chambery forms a central finished circular tapered bearing A7.

Fig. 7'lis agthese ports is in the same tangential'direcsteam-ports B, corresponding in number.

with ports B in the bearing A7. These ports in cross-section are V-shaped, the apex of the angle of each port being on an imaginary concentric circle through the longitudinal center of the bearingAS. i

The tangential direction of the inner half B2 ofthe ports B in the. bearing A8 is opposite to the tangential direction of the ports B in the bearing A7, the tangential direction of the outer half B3 of the ports B2 being the same as that of the portsB. Spaced from the bearing A8 is the outercylindrical part A9 `of they stationary half A. The interior periphery A10 of this partis finished to a taper bearingsurface. Extending through this cylindrical part is a series of steam-ports B4, the same in number, shape, and direction as the ports in the bearing A8. These ports open into anI exhaust-chamber B5, which encircles this series of ports and permits the steam therefrom to escape through an exhaust-pipe B". At the bottom of the V-shaped spaces C are' annular channels C.

` The rotatable half D `of the engine is adapted to fit the concentric bearingsin the stag y* tionary half A. The central part forms a taper cylinder D', adapted to fit on the bearing A7. The wall D2 of this cylinder is taered externally to fit the inside face of the caring A8. Extending through this Wall is a series of steam-ports E,corresponding in number with the ports B in the bearing A7,.

In cross-section these ports are V-shaped,

the apex E of the angle being on an imaginery concentric circle through the longitudiy nal center of the wall D2 of the cylinderl D.v The direction of the inner half E2 of eachof tion as that of the ports B in the bearing A7, the outer half E3 of each port extending at an angle thereto in the opposite direction. The inner openings E2v of` these ports correspond in size and register with the ports Bin the bearing A7, and the outer openings vE3 registerwith the inner openings B of the bearing A8. Spaced from and concentric with the wall D2 of the cylinder D and forming an integral part of the half D is a cylindrical ring D3. This ring is tapered and adapted to fit in the annular space C formed, 'by the bearing A8 and bearing-surface A10' of IIO the outer cylindrical part AD of the main part A. Extending through this ring is a series of ports E4, corresponding in number with and 'in the same angular shape and direction as ports E in the part D2. These ports are adapted to register with the ports B and B3 in the bearings A8 and A9. At the bottom of the spaces F are channels F. The channels C and F at the bottom of the spaces C and F are adapted to allow a clearance for the ends of the bearing-surfaces, and thereby prevent the wearing of shoulders therein.

When the two halves of the engine are constructed and finished as described and shown and the part D is placed into the part A and adjusted therein by any suitable means adapted to hold the parts in adjustment, the operation of the engine is as follows: A steam-supply is turned into the chamber A5 through the supply-pipe A4. The steam passes from this chamber through the ports B and is deflected so that it strikes the inner half E2 of the ports E in the rotatable part D of the engine and is again deflected by the outer half Esof the ports E and then enters the ports B in the part A. The action of the steam against the angular faces of the ports E forces the part D to rotate in the direction of the arrows. The steam is deflected again in the ports B in the direction of the rotation of the part D. The steam then enters the ports E4L in the part D, im-

'pelling the part D in its rotary motion, and

escapes through the ports Blinto the exhaustchambers B5, from whence it passes out of the engine through the exhaust-pipe B". The rotary movement of the part D can be transmitted from the shaft G or by other means affixed or attached to any part of the outer surface of the part D.

Itis obvious that when the steam is turned into the engine if the ports E in the cylindrical part D2 do not register with the ports B of the steam-chamber A5 a slight rotary movement of the part D will bring the ports into line and the engine will rotate at once. It is also apparent that the number of concentric cylindrical bearing-surfaces and series of ports in the fixed and rotatable parts of the engine can be increased 'with the size of the engine and the engine be thereby adapted to utilize the full expansive force of the steam as it passes through the ports from the center to the circumference. For the purpose of retarding the passage of the steam through the ports of the rotating part of the engine and to thereby increase its propelling force l construct the forward wall of each of said ports 'with corrugations H, as shown in the fractional detail sectional view in Fig. 7. It is also obvious that the stationary body may be made of a back plate and supportingbase and that the steam-chamber and concentric cylindrical bearings can be finished in separate parts and attached to said back plate, and so with the rotatable part. The main body forming the back of that part can be prepared and finished and the concentric cylinders attached thereto.

The engine can also be adapted so that the number of ports may vary in both the stationary and rotatable parts and the steam be admitted through the periphery of the engine and exhaust throughout its central part, and any fluid under pressure can be used as the propelling or impelling force.
