Application led October 18, 1916. Serial No. 126,371.

To all whom t may concern.'

Be it known that I, JOSEPH II. KELLEY, a citizen of the United States, residing at Westlake, in the parish of Calcasieu and State of Louisiana, have invented a new and useful Engine, of which the following is a specification.

The device forming the subject matter of this application is a rotary engine.

One object of the invention is to improve the rotor construction, and another object of the invention is t0 improve the valve mechanism.

Another object of the invention is to provide novel means for connecting the stators together.

A further object of the invention is to pr0- vide novel means whereby the exhaust, having acted on a high pressure rotor is delivered to a low pressure rotor.

It is within the province of the disclosure to improve generallyT and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in horizontal section, a rotary engine embodying the present invention;

' Fig. 2 is a vertical section on the line 2-2 of Fig. 1, the line 1-1 in Fig. 2 vindicating the cutting plane on Fig. 1;

Fig. 3 is a vertical section on the line 3-3 of Fig. 1, Figs. 2 and 3 being turned on the sheets through a quarter circle in respect to Fig. 1.

Fig. 4 is a cross sectional view showing one of the hub rings;

Fig. 5 is a perspective view showing one of the blades of the rotor; and

Fig. 6 is an elevation showing the hub ring delineated in Fig. 4.

vIn the accompanying drawings, the numeral 1 indicates a main stator. Connected with the lower portion of the main stator 1 is a lower exhaust conduit ,3.` There is Ia port 2 in the main stator l which leads from the central chamber 6 of the main stator to the lower exhaust conduit 3. An upper exhaust conduit 5 is secured to the top of the main stator 1. There is a port 4 in the main stator 1 which forms a communication between the chamber 6 and the upper exhaust conduit 5. The main stator' 1 has inlet ports 7, 8, 9 and 10. Ihe ports 9 and 10 are located on one side of the stator, and the ports 7 and 8 are located on the other side of the stator. The ports 7 and 9 are located above the ports 8 and 10. Valve chests 12 and 14 are secured to opposite sides of the main stator 1. The ports 9 and 10 communicate with the valve chest 12, and the ports 7 and 8 communicate with the valve chest 14.

The numeral 15 denotes an auxiliary stator abutting against the main stator 1. The auxiliary stator 15 has a central chamber 34 corresponding with the chamber 6 of the main stator 1. The auxiliary stator 15 has opposed exhaust ports 16 and 17. The numeral 18 designates a casing secured at 19 to the auxiliary stator 15 and secured at 2O to the valve chest 12. In the chest 12 there is a port 21 which communicates with the casing 18. The numeral 22 designates a casing secured at 23 to the auxiliary stator 15 and secured at 24 to the valve chest 14. The valve chests 12 and 14 and the casings 22 and 18, therefore, serve to hold the stators 1 and 15 together. The chest 14 has a port 25 which communicates with the casing 22.

In the lower end of the auxiliary stator 15 there is formed a valve chamber 26. In the upper end of the auxiliary stator 15 there is formed a valve chamber 27. The ends of the chambers 26 and 27 are closed by removable heads 28. Pressure fluid is supplied to the chamber 27 through a port 29, steam being supplied to the chamber 26 through a port 29. These ports may be located as desired.

If it is considered desirable to fashion the stators 1 and 15 in separable parts, they may be held together by bolts 100.

In the stator 15 are formed ports 30 and 31 of rectangular form, the ports communi eating with the chamber 27 and discharging 1 into the chamber 34 in a tangential direc-- tion. Similar ports 32 and 33 connect the chamber 26 with the central chamber 34 of the stator 15. The port 31 is controlled by a slide valve 35 and the port 30 is controlled by a slide valve 36. The valves 35 and 36 are adjustably connected by means of nuts 37 or otherwise with a rod 38 slidable in a gland 39 carried by one of the heads 28. A link 40 forms a pivotal connection between the rod 38 and a walking beam 41 fulcrumed intermediate its ends as shown at 42 on the member 18. The port 33 is controlled by a slide valve 43, and the port 32 is controlled by a slide valve 44. The valves 43 and 44 are adjustably held by means of nuts 45 on a rod 46 slidable in a gland 39a carried by one of the heads 28. A link 47 forms a pivotal connection between the outer end of the rod 46 and the adjacent end of the walking beam 41.

The chest 12 is provided with guides 48, and the chest 14 is provided with guides 49. A valve 50 controls the port 8, and a' valve 51 controls the port 7, these valves being slidable in the guides `49. By means of nuts 52, the valves 50 and 51 are adjustably held to a rod 53 slidable in a gland 54 carried bythe chest 14. A link 55 pivotally connects the rod 53 with a Walking beam 56 fulcrumed as shown at 57 on the upper exhaust conduit 5. A valve 58 controls the port 10, and a valve 61 controls the port 9. Valves 58 and 61 are adjustably held by means of nuts 62 on a rod 60 passing through a gland 63 carried by the chest 12. A 4link 64 forms a pivotal connection between the exposed end of the rod 60 and the 'adjacent end of the walking beam 56.

Mounted in the outer end of the chamber 6 of the main stator l is a bearing plate 65. Mounted in the outer end of the chamber 34 of the stator' 15 is a bearing plate 66. Mounted in the inner ends of the chambers 6 and 34 of the respective stators is an intermediate plate 70. A shaft 67 is journaled in the plates 65, 66 and 7 0.

A high pressure rotor operates in the chamber 34 of the stator 15, and a low pressure rotor operates in the chamber 6 of the stator 1. The high pressure rotor includes a hub 68, and the low pressure stator includes a hub 69, the hubs being secured to the shaft 67 to impart rotation thereto. A plate 71 is interposed between the intermediate plate and the inner end of the hub 68 of the high pressure rotor. A plate 72 is interposed between the plate 70 and the inner end of the hub 69 of the low pressure rotor. A plate 73 is interposed between the outer end of the hub 68 of the high pressure rotor and the bearing plate 66. A plate 74 is interposed between the outer end of the hub 69 of the low pressure rotor and the bearing plate 65. The plates 71 and 72 are prevented from rotating by means of pins 75 slidably'received in recesses in the intermediate plate 7 0. Springs 76 are mounted in therecesses of the plate 70 and serve to thrust the plates 71 and 72 in opposite directions. The plate 73 is provided with-pins 77 slidably received in recesses in the bearing plate 66.

serve to thrust the plate 73 inwardly. Pins 79 are carried by the plate 74 and are slidably received in recesses in the bearing plate 65. Springs 80 are located in the recesses of the bearing plate 65 and serve to thrust the plate inwardly.

The hubs 68 and 69 of the rotors are provided with longitudinal dove tailed recesses 81.

Plates 87 are provided, and the same are equipped with ribs received in dove-tailed recesses 81 in the hubs 68 and 69 of the rotors. Rings 85 surround the ends of the hubs 68 and 69 of the rotors. The inner faces of the rings 85 are equipped with radial grooves 86. Trough-shaped blades 82 slide radially on the plates 87, the blades 82 preferably being open at one end as shown at 84. The ends of the blades slide in the grooves 86. Springs 88 are carried in the plates 87 and, coperating with the blades 82 force the same outwardly to for-m a fluidtight joint with the walls of the chambers 34 and 36. The springs 76 force the plates 71 and 72 in opposite directions, the plates 72 bearing on the innerV rings 85. springs 80 and 78 force the plates 74 and 73 inwardly, causing the same to coact with the outer rings 85. 1n this manner, fluidtight `ioints are effected between the blades 82 and the rings.

Let it be supposed that the valve 44 is open, the valve 43 being closed, the valve 35 being open, the valve 36 being closed, the valve 51 being closed, the valve 50 being open, the valve 61 being open, and the valve 58 being closed. Suppose that the rotors are turning in a clockwise manner in Figs. 2 and 3. Pressure fluid from the chamber 26 passes through the port 32 into the chamber 34 and turns the high pressure rotor of which the hub 68 constitutes a part. The fluid leaves by way of the exhaust port 16 and passes into the casing 22, the fluid thence passing by the way of the port 25 into the chest 14 and into the port 8, there- Springs 78 are seated in the recesses of the plate 76 and The by entering the chamber 6 and causing the low pressure rotor to turn. Fluid, as exhaust, traverses theport 4 and the exhaust conduit 5.

Fluid traversing the port 31 enters the chamber 34 and turns the high pressure rotor, the fluid leaving by the port 17 passing into the casing 18. Thence, the fluid passes by way of the -port 21 into the chest 12 and by way of the port 9 into the chamber 6, the low pressure rotor being turned. From the chamber 6 of the low pressure rotor, the fluid leaves as exhaust by way lof the port 2 andthe exhaust outlet- 3.

It is possible Vto reverse the engine by shifting the valves, the valve 44 being closed, the valve 43 being open, the valve 35 being closed, the valve 36 being open, the valve 51 being open, the valve 50 being closed, the valve 6l being closed and the valve 58 being open.

In view of what has been said hereinbefore, the path traversed by the fluid when the valves are reversed, will be understood readily.

It is obvious that the structure hereinafter claimed may be used on a one-way engine, instead of a reversing engine.

Having thus described the invention, what is claimed is 1. In a rotary engine, a low pressure stator having a rotor chamber and provided with oppositely disposed exhaust ports; oppositely disposed exhaust conduits mounted on the stator and communicating with the chamber through the exhaust ports; oppositely disposed chests mounted on the stator and communicating with the chamber; slide valves operating in the chests; a walking beam fulcrumed on one of the exhaust conduits and connected with the valves; a high pressure stator disposed at one end of the low pressure stator and having a rotor chamber; op-
