ABSTRACT:
The Assembly is formed of individual, radially-fingered plates, set upon a body, in surmounting relationship, and fastened to the body by a central bolt. The Method calls for the provisioning of the body and the radially-fingered plates, setting the plates upon the body, fastening the plates thereon, and bending the fingers, angularly from their plates, into a common parallelism, with the ends of the fingers all terminating in a common plane. The kit sets forth the components for an Assembly: a plurality of radially-fingered plates, a body, and a fastener for fixing the plates onto the body. The Plate is flat, having a uniform thickness, with radially-extending fingers, and apertured in a central portion thereof.
