To allavhom it may concern:

Be it known that I, ANnERs W. WINBERG,

citizen of the United States, -.residing at Bedding, in the county of Shasta and Stateof. California, have invented certain new and provide a very simple form of rotary engine in which the steam reacts against a comparatively large number of blades, and in the course of its travel passes from the exterior of the rotor to the interior thereof, through a number of chambers in its passage and eventually exhausting from the central por t-ion of the rotor.

Another object is to provide an engine of this type with very simple means whereby the engine may be reversed whenever de- "sired without the necessity of using complicated valve gears for this purpose.

The invention contemplates in its general features a rotor provided with a plurality of radiating blades in conjunction with a plu-- -ra1ity of steaminlet valves actuated by the rotation of the rotor, which valves while acting to prevent the entrance of steam behind each of the outer blades of the rotor also act as abutments against which the steam reacts in forcing the rotor around.

The-invention is shown in the accompanying drawings wherein:

Figure l is a side elevation of an-engine constructed in accordance with my invention. Fig. 2 is a vertical section thereof on the line 2-2 of Fig. 3. Fig; 3 is a vertical section, transverse to Fig. 2 and taken on the line 3-3 of Fig. 1. Fig. 4 is a fragmentary section on the line 4.-4 of Fig. 3. Fig. 5. is

a fragmentary perspective view.of the rotor and one of the rings dividing the outer set of blades from the inner set of blades. Fig. 6 is a perspective view of ne of thevalves. Fig. 7 is a perspective vi w of the tubular axis on which the valve turns. Fig.8 is a diagrammatic view to show the'action of-the steam as it passes from theinlet valves and exhausts from the outer piston space into the next succeeding piston space, acts on the scribed, while the face of the rotor is blades therein and pames out through the exhaust space. Fig. 9 is a fragmentary section of a portion of the casing and the rotor as shown in Fig. 8, showing the position of the valveafter a blade has passed the same.

Referring to these drawings 2 designates a circumferential casing closed at its ends by the side plates 3 and 4, these plates being bolted to the casing 2 by means of the bolts 6. The lower portion of the casing 2 may be shaped to provide any suitable'baseifi upon which the engine may be supported. Projecting from the side plate 4: is the fixed annulus 7.

Passing through the centers of the plates 3 and 4 is the shaft 8 upon which the rotor is mounted, this rotor being designated 9.

The circumference of the rotor is provided" for one-half of the'width of-the rotor with gear teeth 10, for a purpose to be later derovided with a plurality of sets of radially extending piston blades 11, 12 and 13', as'

mostclearly shown in Fig. 8 wherein the gear. teeth 10 are omitted for the sake of clearness. VVhileI do not wish to'limit myself to any specific number of bladesaI'have shown eight outer blades 11, and double. that number of: blades 12 and 13. The inner ends of the blades 11 are spaced from the outer ends of the blades-12 sufficiently to accommodate a relatively fixed annulus or ring 14 which I shall hereinafter term the reversing ring, and the inner ends of the blades 12 and the outer ends of the blades 13 are spaced from each other a distance equal to the thickness of the fixed ring 7, previously referred to.v It will thus be seen that the blades 11, 12 and 13 project out from the face of the rotor and into the spaces between the'outer wall or casing 2 and the ring 14, andbetween the ring 14 and the fixed ring 7, and between the ring 7 and the shaft 8, upon which the rotor turns.

The central portion of the rotor is provided with an annular wall 15 which is cut away between each of the blades 13 so as to form ports 16. through which the exhaust steam passes An exhaust pipe 17 passes through. the plate 4: of the casing, as shown in Fig. 3' and registers with the annular recess or chamber formed between the wall 15. and the hub 18 of the rotor. Thus the exhaust port will always be in connection with the spaces betwen the blades 13, and

no exhaust valves are used for controlling set of blades, and from thence to the chambers or spaces between the inner set of blades, 1 form the exterior annulus 14 with a plurality of inlet ports 19 and provide the interior rlng or annulus 7 with a like number of ports 21. It will be understood that the inner ring or annulus 7 is fixed with relation to the casing, and hence that its ports have a fixed relation, but the reversingring or outer annulus 14 is shiftable through the are of a circle and hence the ports 19 are shiftable into position, as will be later claimed.

In order to provide for the inlet of steani to the outermost set of blades, I form the casing 2 and the side plates 3 and at with a plurality of cylindrical valve casings 22. These casings are shown as four in number but I wish it understood that any number of inlet valves may be used. Passing through each of the valve chambers and extending out on each side of the engine, is the valve axis 23 which is tubular and is provided with ports 24 and 25. These ports are diametrically opposite to each other but are longitudinally spaced so as to aline with certain longitudinally spaced ports in the rotatable valves, one of the valves being shown in Fig. 6. Each valve comprises a central tubular core which surrounds and rotates upon the inlet pipe or tube 23, and a cylindrical body which fits the valve chamber 22. and rotates therein. The side wall of the valve chamber opens into the interior of the casing so that the valve projects therethrough and into contact with the exterior face of the rotor. One-half of the face of the valve is provided preferably with teeth 26 which are adapted to be en gaged by and mesh with the teeth 10 on the rotor. The other portion of the valve is cylindrical and has a smooth outer face so as to engage with the face of the rotor, as

previously stated. The body of the valve is formed with the longitudinally extending, oppositely disposed V-shaped recesses 27 and 28 which are provided to permit the blades 11 to pass the valve. As seen in Fig. 4: each valve is formed with passages 29 and 30 which extend from the hollow interior of the valve to the oppositef'aces of the V shaped recesses 27 and 28. One of these passages 29 opens upon the interior of the valve at such a point that it will intermittently register with the port 25, while the other passage 30 is so arranged as to intermittently register with the port 26. -The ports 25 and 26 are separated from each other by a dividing partition 32 so that while the axle 23 of the valve is open at pass from one portion of semen opposite ends to admit steam, steam can not the valve into the other. When therefore, through one end of the valve axle it will pass out of the port 2% for instance, and will pass into the passage 29 and be delivered in one direction against the face of the blade 11. l vhemhowever, steam is cut off from the first named end of the axle and enters the other end thereof, steam will pass down through the port 25 which will intermittently register with the passage 30, and thus the steam will be delivered in the other direction and against the faces of the blades.

It will be seen that as the valves mesh with the teeth 10 the valves will be given a steam is admitted.

constant rotation, and that the valves are I so arranged that the recesses 27 will mesh with the blades 11, thus permitting the blades to pass the valves, and that as soon as a blade has passed the valve, steam will be directed against the rear face of the blade, the valve in that case acting as an abutment, or practically forming a fixed end tothe steam space, the other end of which is formed by the moving blade.

Referring to Fig. 8 it will be seen that the steam will pass out from the inlet valve into a space between the outer casing and the reversing ring 14: and will act against the blade 11, carrying the blade forward until the blade has reached and passed one of the ports 19, which port in the position of the reversing ring shown in Fig. 8, is disposed on one side of the adjacent inlet valve. When the blade has passed the port 19, the steam behind the blade which is exhaust steam will pass through said port and into the next inner steam space, until such time as the blade 12 reaches and passes-one of the ports 21 in the inner annulus 7. The steam will then escape through said port, to the chambers or spaces between the inner set of blades 13 and will from thence pass to the exhaust pipe 17, by which the steam is finally carried off. It will thus be seen 1 that I secure a turbine action in my rotor compelling the steam to impinge upon a plurality of blades in the course of its passage from the exterior of the rotor to the interior thereof.

It is for the purpose of reversing the movement of the rotor that I have provided the shiftable reversing ring 14. The direction of rotation of the rotor depends upon the position of the ports 19 with relation to the inletvalves. If the ports 19 are on one side of the inlet valves, the engine will move in one direction, whereas if the reversing ring is shifted to bring the ports to the- 37 which moves over a sector 38 and is .pro-

.vided with a, latch 39 whereby the lever may be held. in any adjusted position. It will thus be seen that by moving the lever to one side or the other that the ring 14 will be shifted to carry its ports to one side or the other of the inlet valves. There are four inlet valves as shown, each formed with two blade recesses 22, and hence the,- rotor is shown as' being formed with eight outer blades 11, and the rings 7 and 14-are shown as being provided with four ports, however,.be understood that I may increase or decrease the number of piston blades on the rotor, and change the other parts of the apparatus to correspond.

It will be noted that the engine as shown takes steam at four points, thatfthis steam is almost immediately cut off, and then acts expansively until it passes into the exhaust 1 e. p If the engine should stop on a center so that the valves would be so turned as to prevent steam being applied to one side of a blade and notto the other, and there -fore preventing. the forward movementof or 40, depending upon which way the rotor is to be moved.

The extremities of each of the valve -a-x'les 23' are connected the pipes 44 and 45 to a-source of steam supply, these pipes extending to a.common supply p1pe46 provided with a valve 47, whereby the steam may be directed into-either branch pipe 44 v or 45' for the purpose previously described,

that is, for rotating the rotor in one direction or the other as desired.
