 Having now particularly described and ascertained the nature of this said invention, and in what manner the same is to be performed, I declare that what claim is:

1. The method of imparting energy to or deriving it from a fluid, based on adhesive and viscous action, which consists in admitting the fluid to the central or peripheral portion of a rotably arranged system and causing it to flow, under the combined action of radial and tangential forces, in a spiral path towards the periphery, or the axis, of the rotating system, as set forth.

2. As an improvement in the transmission of power the method of imparting energy to or deriving it from a fluid, based on adhesive and viscous action, which consists in causing the fluid to flow, under the combined action of radial and tangential forces, in curved paths away from, or towards the axis of a rotably arranged rigid system, as set forth.

3. The method of imparting energy to or deriving it from a fluid, based on adhesive and viscous action, which consists in admitting the fluid to the central or peripheral portion of a rotably arranged system and causing it to flow, under the combined action of radial and tangential forces, in a spiral path with gradually increasing or diminishing velocity towards the periphery, or the axis, of the rotating system, as set forth.

4. The method of deriving energy from a moving fluid, based on adhesive and viscous action, whioh consists in admitting the fluid to the peripheral portion of a runner and causing it to give up its energy of movement while flowing with continuously diminishing velocity in a spiral path towards the axis of the runner, as set forth.

5. The method of imparting energy to a fluid, based on adhesive and viscous action, which consists in admitting the fluid to the central portion of a runner and causing it to flow, by the combined effect of the tangential and radial forces, in a spiral path with continuously increasing velocity towards the periphery of the runner, as set forth.

6. A fluid propelling or fluid propelled machine consisting in the combination of a shaft, a plurality of disks spaced apart and mounted on the same, and ports or passages of inlet and outlet adjacent to the center and periphery of said disks, as set forth.
