Field of Invention The present invention relates to prime movers and particularly to a turbine machine used for converting a natural source of energy into mechanical energy.

2. Description of Prior Art Heretofore, in the art of turbines, particularly when used in an engine, it has been known to apply a force in the form of a fluid under pressure to vanes at the periphery of a turbine wheel. The turbine wheel is normally fixed to a shaft and as the turbine wheel turns, the shaft turns in order to do work. For instance, in a water turbine, water under pressure is directed to the vanes at the periphery of a turbine wheel which is directly coupled to the rotor in an electrical generator through a shaft. Such equipment requires considerable space, i.e. the turbine must be separate from the generator.

SUMMARY OF INVENTION It is an aim of the present invention to provide a novel turbine arrangement which can be compact and can be adapted to uses not before possible with conventional turbines.

In accordance with the present invention, there is provided a turbine wheel suitably adapted to transmit mechanical energy, the turbine wheel comprising a plurality of vanes, the vanes each including a leading edge spaced from the center of the wheel and a trailing edge towards the periphery of the wheel, a source of fluid under pressure, means for directing said fluid under pressure radially outwardly towards the leading edge of the turbine wheel whereby saidfluid impinges on said vanes.

BRIEF DESCRIPTION OF THE DRAWINGS Having thus generally described the nature of the invention, particular reference will be made to the accompanying drawings showing by way of illustration, preferred embodiments thereof, and in which:

FIG. I is a top plan view partly in section of one embodiment of the invention;

FIG. 2 is a vertical diametrical cross section taken through the embodiment shown in FIG. 1;

FIG. 3 is a vertical cross section taken along line 3-3;

FIG. 4 is a schematic top plan view of a further embodiment of the present invention;

FIG. 5 is a side elevation of the embodiment shown in FIG. 4.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring first to FIGS. I to 3, the embodiments shown therein are directed to a generator. The generator is indicated generally by the numeral 10. The generator includes a frame 12, and a housing 14. The housing 14 is mounted to the frame 12.

A support block I6 is located centrally and below the housing and supports bearings 18. A stator having a shaft 28 is fixedly mounted to the support block 16. Surrounding the stator 20 is the rotor casing 22 having a rotor winding 24 of cylindrical configuration.

Mounted to the free end of the stator shaft 28- are ball bearings 30 about which are mounted bearing frame members 26. Frame 26 is connected to the rotor casing 22 and mounts fixed bearing shaft 32.

The parts which are duplicated in the drawings will be described with reference to only one of the turbine wheel assemblies, although similar parts in the other turbine wheel assembly will be raised by the subscript 4.

Wheel 34 is journaled to the bearing shaft 32. Turbine wheel 34 includes curved vanes 36 as best seen in FIG. 3.

About the periphery of the turbine wheel 34 are gear teeth 38 which are adapted to travel in a circular path defined by the gear track 40.

An inverted Y-shaped conduit 42 is provided in the housing and is fixed at each end to the bearing frame 26. Discharge opening 43 of the conduit 42 is directed in a vertically downward direction towards the leading edges of the vanes 36 as shown in FIG. 3. The conduit 42 is coupled to a main delivery conduit 48 by means of a bearing coupling allowing the inverted Y-shaped delivery conduit 42 to rotate about he axis of the main conduit 48.

It has also been contemplated to use two pairs of wheels 34, rather than one pair. This could double the output in a generator of substantially the same dimensions. 7

In operation, water under pressure is forced down the main conduit 48 into the conduit 42 at which point it is diverted to either the

turbine wheel

34 or 34a. As the water rushes out the discharge nozzle 43 of the conduit 42, it, impinges upon the curved vanes 36, forcing the wheel to rotate in a counterclockwise direction'as shown in FIG. 3. Of course, wheel 34a is reversed and as the water comes out of the discharge 43a, the wheel rotates in a clockwise direction. This forces the wheel to travel on the track 40 by means of the gear teeth 38 on the wheel 36. Since the rotor casings 22 are fixed to the bearing frame 26 which also rotates with the

wheels

34 and 34a, a generator relationship between the rotor windings and the stator windings isr'produced, therefore providing electricity.

In the second embodiment shown in FIGS. 4 and 5, a turbine wheel is shown in an embodiment on a boat 60. There is provided a water conduit 62 from a pumped water source which is directed to the center of the turbine wheel 64. Water discharging from the conduit 62 of the inner lead-ing edges of the vanes on the turbine wheel 64 causes the turbine wheel 64 to. rotate, thus directly turning coupled shaft 66 which turns the propeller 72 through the intermediary of gears 68 and 70.

Many other embodiments can be devised using the type of turbine wheel described above in which the fluid under pressure is fed radially outwards to the leading edges of the vanes in which the periphery of the turbine wheel can either have ground engaging surfaces for use in a land vehicle, for instance, where the turbine wheel can remain fixed with the turbine wheel mounted fixedly and eccentrically to a shaft. The force of the water on the fixed vanes of the fixed turbine wheel will cause the shaft on which it is mounted to rotate.
