Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
145 words
A flexible coupling including a pair of coupling members having interpenetrating jaws positioned to provide circumferentially spaced areas between adjacent pairs of interpenetrating jaws, each pair of jaws having opposed, flat, straight, parallel sides defining the circumferential extension of one of said areas, individual load cushions positioned one in each said area, each of said load cushions having a body portion positioned between a pair of said opposed, flat sides of adjacent jaws, the sides of said cushion body portions opposed to said jaw sides being convex whereby a progressively greater area of said body portion is contacted by its opposed jaw side as said area is reduced, each of said load cushions having oppositely directed, circumferentially disposed shoulder elements at its outer end, the shoulder elements of each of said cushions engaging the outer edge surfaces only of a set of adjacent, opposed jaws.
Claim 2
Dependent Claim
145 words

Claim 3
Dependent Claim
84 words
The structure of claim 1 characterized by and including an outwardly open, circumferentially directed groove disposed laterally on and bisecting the outer surface of each of said cushions and the shoulders thereof, a flat clamping band encircling said cushions, said band enGaging the outer surfaces of said cushions and the shoulders thereof and urging said shoulder portions against said outer jaw edge surfaces and an annular, inwardly extending rib on said band, said rib being received within and occupying the entirety of said grooves.
