To all whom it may concern:
Be it known that I, AnoLrH G. CARLsoN, a citizen of the United States residing at Chicago, in the county of Cook and State of Illinois, have invented. a certain new and useful Improvement in Rotary Gas-Engines, of which the following is a specification.
This invention relates to rotary gas engines and has for its object to provide a new and improved engine of this description. a
The invention isillustrated in the accompanying drawings wherein Figure 1 is a side elevation of one form of engine embodying the invention; Fig. 2 is an end elevation 'of the device shown in Fig. 1;
, Fig. 3 is a sectional view taken on line 33 7 device.

12 is a sectional view taken on line 1212 of Fig. 4'; Fig. 13 is a sectional view taken on line 13-13 of Fig. 6.
Like numerals refer to'like parts throughout the several figures.
Referring now to Figs. 1 and 2 wherein I have shown one form of engine embodying the invention, said engine is provided with a suitable casing made up of a section 1 containing a turbine wheel, and a section 2 containing the explosionchambers. The engine is provided with a driving shaft 3 by means of which the power is applied to the driven The carbureter 4 is connected to the fuel supply by a pipe 5. The fuel supply enters the carbureter andis mixed with air and passes to the explosion chamber by way of pipe 6. Air for the carbureter is supplied from the turbine wheel by means of Referring now to Fig. 3, the turbine wheels 8 are-connected with the shaft 9 so as to drive the same. Connected at the periphery of the turbine wheels 8 are the turbine blades 10. The wheels 8 are also built as fan impellers any desired arrangement bethereby kept cool at all times. The air enters the casing 1 through the openings 12. The air passes up through passage 13 into the hollow part 14: of the first turbine wheel. It then passes through the hollow turbine blade 10 into an air passage way 15 in the casing. It travels from this passage way 15 through the stationary blade 11 and then through the passage way 16. From the passage way 16, it enters the hollow part 1 1 of.
the next turbine wheel and is passed up through this blade and through the next air passage 15 and through the next stationary blade 11 and into the hollow stationary part 16 and thence through the next turbine wheel. The air passes out through openings 17, of which in the particular construction shown there are three in number. One is connected with the earbureter 4 as shown in Figs. 1 and 2, and another is connected with the port 26 leading to the explosion chamber, and the other leads to nozzles on each side of the nozzle through which the exploded gases pass to the turbine Wheels so that air may be mixed therewith to prevent the turbine wheels from getting too hot.
Associated with the turbine wheels is the explosion chamber 1'8. In this explosion chamber are a series of valves 19 which are connected by means of a disk 20 with a vents its escape. The valves and explosion chamber are made in halves to facilitate the machine work and are assembled into the complete structure. The explosion chamber may be Water or air cooled by means of the chambers 24. The gas from the carburetor passes through pipe 6 into the explosion chamber 18 through the port 25. In order to discharge the burnt gases from the section of the chamber in which the explosion has occurred and after the valves have moved so as to disconnect this section from the chamber containing the turbine blades, air from one of the. openings 17 is directed through port 26 into such section of the explosion chamber and drives the burnt gas out of the port 26*. The ports 25, 26 26 and 27 are controlled by the valves 19. When the explosive mixture enters the port 25, the port 27 will be open so that the air in the section of the explosion chamber into which the explosive mixture is entering will be driven out through said port 27. The outlet port 26 is connected with a pipe 28 (see Fig. 2) controlled by a. valve 29. As the valves 19 move forward, the port 27 is closed and the section between the two valves is filled with. explosive mixture through the port 25. As the valves move forward this section of explosive mixture is carried forward and just as the port 30 is opened, the
gas is exploded by means of the spark plug 31, and passes through the port 30 and the nozzle 32 (see Fig. 3) into the chamber containing the turbine blades. The gas striking the turbine blades causes a rotation thereof,
and then passes out into the exhaust chamber 33. After this mixture is exploded and explosive gas is then received and the operation repeated.
It will be seen that in the construction shown that there are three explosive spaces between the three valves, each one being charged with the gas, the gas then exploded and discharged and then re-charged, making a continuous cycle of operation, the exploded gasunder pressure being discharged against the air-cooled blades of the turbine wheel so as to drive the shaft 9. In larger turbines, I may use six, nine, twelve, or any other number of these valves that may be desired. The shaft 9 is mounted upon suitable hearings in the casing and is connected with the driving shaft 3 by reducing gear"- ing. In the particular construction shown, the shaft 9 is provided with a pinion 34 which meshes with a plurality of gears 35. In the particular construction shown, there are two of these gears 35, but any other number desired may be used. The gears 35 engage the internal gear 36 on the frame and are mounted upon a rotating frame 37 which is connected to the shaft 3 so as to rotate it.
Disk 20 which is connected to valve 19 in p sage 42 and passes through the nozzles 40 and 41 located on opposite sides of the nozzle 32 through which the hot gases pass to the turbine blades (see Fig. 7). This air becomes mixed with the hot gas which propel the turbine blades and prevent the turbine blades from becoming too hot. The turbine wheel casing is also provided with another nozzle 43 (see Fig. 13) through which is dischargedthe air and foul gasdriven out of the explosion chamber through the port 26*. This gas strikes the turbine blades and exerts its force thereon so as to create a certain amount of power. At the end of the shaft 9 I prefer to'provide a generator 44 of the magneto type for ignitionpurposes. This generator may be of any suitable type and I therefore have not described it in detail. The conductors 45 from this generator lead to the spark coil 46 and from this spark coil to the spark plugs .31 and 47 the latter plug being inserted in the passage way leading from the explosion chamber to theturbine wheel chamber (see Fig. 3).
It will be noted that when the engine is in operation, the air set in motion by the turbine wheel passes through the movable turbine blades and stationary hollow blades so as to cool them and that it is this heated air which enters the.explosion chamber to scavenge it and enters the carburetor to supply air thereto as hereinbefore described.
