Be it known that I, HERBERT H.' CABLE, a citizenA of the United States, residingat Los Angeles, in the county of Los Angeles andState of California,.have invented new and useful Improvements in Engines, of which the following is a specification.

' This inventionrelates to engines of the turbine or rotary type, the broadV object of ,groups of stators 10, the groups progressively increasing in capacity toward the exthe invention Abeing to generate and utilize steam' fory driving the turbine elements or stators of thefengine vand at the same time utilize an explosive mixture which is ignited in the engine `and delivered concurrently with the steam into the casing in whichthe rotors operate,-the combined fluids beingdirectedl against and through the rotors and stators and being exhausted through a common outlet. y

,A further object of the invention is to eliminate all valves in the turbine section of the engine, and eliminate to a considerable extent end thrust on the engine shaft and the drum on which the rotors are mounted.

The result is an engine of high eiiiciency, operating under a lluid or combination of fluids producing anelastic pressurev against the working parts of the turbine section of the engine. f y

VVith'the above and other objects in view,

i the invention consists in the construction,

combination, and varrangement of parts, as herein described, illustrated and claimed. In the accompanying drawings i Figure 1 is a vertical longitudinal section through the improved engine taken in line with the engine shaft, the latter beingshown in elevation.'

tion 4 ofr a frame 5, while the other bearmgs 2 are supported in casings 6 having connection with the heads 7 of the casing 8 oftheturbine section of the engine. The inner head 7 of the casing 8 is shown as ,forming a partof the frame 5,k the cylindricalv portion of the casing 8 being flanged and bolted to the frame 5 as shown at 9.

lWithin the casing 8 there are arranged Y tors 12, all yof said rotors being secured to and encircling a hollow drum or shaft 13 which 1s of stepped formation as shown in Fig. 1, the same comprising the steps 14, 15

and 16 which are of progressively decreasing diameter as clearly shown. vBy reference to Fig. 2, it will be seen that each stator is provided with V-shaped' vanes 17 forming the V-shaped orar-cuatel passages therebe tween, each stator also comprising a peripheral rim` 18'having internal reaction shoulders-or surfaces 19.Y By reference to Fig. 3, it will also be observed that each rotor isr providedwith concentric series of V-shaped vanesy 20,-fthe vanes 2O being disposed reversely to the vanes 17 of the stators, the expansion fluidV acting directly on the vanes 20 and reacting upon the vanes 17 and sur- The fluid 0r rfluids through, and leaving the casing 8 following the direction of the arrows and dotted lines in Fig. l, wherein it will be observed that after the fluid acts upon one statory and rotor, moving outwardly from the centertoward 'the peripherythereof, such fluid isrdirected again towardV the center of the next adjacent rotor Iand .stator through an L-shaped passage 21, ,there being such a passage `between each couplet of rotors and stators as clearly The rotors are held upon is keyed or otherwise fastened to the engine rshaftl as shown at 23.

`UJon the frame 5' there is mounted an j acketed as shownat 25. The said frame or engi-ne frame or oastingl24cv which is water casting comprises a` mixing chamber 2G best shown in Fig. 5, said mixing chamber being adapted to be closed vat the top by a puppet valve 27 and also adapted to be closed at the bottom by a similar valve 28, said valves having stems 29 and 30 working in suitable guides 31 and 32 and the valves being held yieldingly to their seats and returned there# to by means of springs 33. The valves 27 and 23 are simultaneously opened by means of a cam 34 on a cam shaft 35 suitably geared to the engine shaft 1. Located above the mixing chamber 26 is a water inlet chamber 36 which. communicates with the mixing chamber 26 by means of a passage 37. Torking in the chamber 36 is a rotary Vater inlet and measuring valve 38 having a single port 39 extending diametrically therethrough. Said valve 38 is of cylindrical formation and actuated by a shaft 40 which is suitably geared to the engine shaft and driven at the proper speed. A pipe 41 leads from an overhead water tank 42 to the chamber 36, the water from said chamber 36 to the mixing chamber 21 being controlled by the valve 3S which delivers the water in the proper quantity to said mixing chamber 2G. The pipe 41 is equipped with a feed regulating valve 43. The valve 27 controls an outlet passage 44 leading off i from the mixing chamber 26 and connected by a pipe 45 to a steam pressure tank 46 from which the steam is conducted into the casing 8 as will hereinafter appear. The valve 28 controls communication between the mixing chamber 26 and an explosion or combustion chamber 47 which is elongated provided adjacent as shown in Fig. 1 and to one end thereof with a mixture inlet 43,

the inlet being controlled by an inlet valve 49 yieldingly held to its sea-t by means of a spring 50 and positively opened by means of a cam 51 on a cam shaft 52 suitably geared to the engine shaft.` Between the inlet valvev 49 andi the valve 28, there is placed an ignition element such as a spark plug 51. At the other end of the comi bustion chamber 47 there is an exhaust chamber 52 controlled by an exhaust valve 53 yieldingly held a cam shaft 56 suitably geared to and actuated by the engine shaft. From the chamber 52, a pipe 57 extends to and through the adjacent head of the casing` 8, the final portion of the pipe 57 being enlarged as shown at 58 to adapt it to receive an L-shaped steam nozzle 59 the steam from the tank 46 and delivers the same into the enlarged portion 58 of the pipe 57, the mixture being then delivered to an annular jet pipe or manifold 59 which delivers the mixture through an annular series of jet openings against the initial set of vanes within the casing 8. The expandagainst its seat by a spring f 54 and positively operated by a cam 55 on i lout departing from the principle or which receives ing mixture then travels throughout the length of the entire casing impinging against the vanes of all of the stators and rotors until it escapes through the outlet or exhaust orifice 11. v

. From the foregoing description taken in connection with the accompanying drawings, the operation of the invention will now be understood. The explosive mixture under pressure is delivered to the combustion chamber 47 when the intake valve 49 is unseated. Said valve 49 is then seated and the explosive mixture ignited by the plug 44. At this time, the valve 28 is opened and the small quantity of Water in the mixing chamber 26 is flashed into steam, and passes by the valve 27 and through the pipe 45 into the pressure 46 passing therefrom through the nozzle 59. The expanding mixture in the combustion chamber 47 passes the valve 53 which is opened at the proper moment and flows through the pipe 57, mixing with the steam beyond the nozzle 59, the combined mixture being then delivered into the casing 8, where it acts in the manner above described. As the mixture expands against the rotor and stator members, it moves outwardly in a general radial direction and thus eliminates most of the end thrust to which the rotors and their shaft are generally subjected in the ordinary con struction of turbine engines. The result is a smoother working engine, and greater power efficiency. By thus combining an ex plosive mixture with steam, a highly elastic pressure is obtained rendering the engine flexible and powerful in operation and also economical in the consumption of liquid fuel. Gasolene or any other hydrocarbon oil may be used in conjunction with air as a combustible mixture. The water may, if desired, be drawn from the water `iacket 25 so that water having a fairly high. temperature maybe used for delivery to the mixing chamber 26, thereby facilitating the generation of steam in said mixing chamber.

It will be understood that the engine as a whole is susceptible to changes in the form, proportion and minor details of construction which may accordingly be resorted to withsacrificing any of the advantages of the invention.
