Abstract
Abstract An improved rotatable mass for a flywheel characterized by a plurality of coaxially aligned, contiguous disks mounted on a spin shaft, each disk of the plurality being formed of a plurality of woven fibers disposed in a plane transversely related to an axis of rotation with the fibers of alternate disks being continuous throughout their length, while the midportion of the fibers of the remaining disks of the plurality is removed for defining annular voids concentrically related to the spin shaft.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
69 words
An improved rotatable mass for a flywheel comprising: a mass including a plurality of contiguous, coaxially related disks, each disk being formed of a plurality of woven fibers disposed in a plane transversely related to an axis of rotation extended through the mass, the fibers of alternate disks being continuous throughout their length; and a spin shaft extended through the mass in concentric relation with said axis of rotation.
Claim 2
Dependent Claim
69 words
An improved rotatable mass for a flywheel comprising: a mass including a plurality of contiguous, coaxially related disks, each disk being formed of a plurality of woven fibers disposed in a plane transversely related to an axis of rotation extended through the mass, the fibers of alternate disks being continuous throughout their length; and a spin shaft extended through the mass in concentric relation with said axis of rotation.
Claim 3
Dependent Claim
32 words
The device of claim 1 wherein the midportions of the fibers of the disks interposed between the alternate disks are removed for forming an annular void concentrically related to said spin shaft.
Claim 4
Dependent Claim
31 words
The energy storage device of claim 2 wherein said alternate disks are bonded to said spin shaft and the disks interposed between the alternate disks are bonded to said alternate disks.
