Abstract
The present invention concerns an improvement in force directing apparatus for transmitting force in respective longitudinal directions from a first shaft to a second shaft where the longitudinal axis of such shafts may be misaligned. The shaft coupling apparatus hereof comprises a compound collar means, and a compound force-directing washer means disposed within the collar means. The collar means preferably comprises two portions which are threadably secured to each other, and which contain a central bore portion therein. A compound force-transmitting washer means is disposed therein and includes washer means formed from the group consisting of materials which differ in chemical composition and materials which differ in hardness. Such compound force-transmitting washer means functions to minimize cold flow and self-adhesion which would otherwise over time and use bind the washer layers together.
