Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
182 words
A flexible coupling assembly for connecting a driving member to a driven member comprising: a. a first circular end plate for attachment to the driving member for rotation therewith, b. a second circular end plate spaced from the first end plate for attachment to the driven member for rotation therewith, said first and second end plates each having a circular flat surface and at least one lug extending beyond the flat surface, c. a one-piece flexible plastic molded body having (i) a collar portion at each end engaging the circular flat surface of the first and second end plates respectively, said collar portions each having two bosses for receiving fastening means to secure the collars to the first and second end plates respectively, (ii) a notched area to receive the respective lugs, and (iii) a plurality of spaced outwardly bowed ribs interconnecting the collar portions and spanning the space between the first and second end plates, and d. fastening means holding the two bosses of each collar portion together to thereby secure the molded body to the first and second end plates.
Claim 2
Dependent Claim
182 words
A flexible coupling assembly for connecting a driving member to a driven member comprising: a. a first circular end plate for attachment to the driving member for rotation therewith, b. a second circular end plate spaced from the first end plate for attachment to the driven member for rotation therewith, said first and second end plates each having a circular flat surface and at least one lug extending beyond the flat surface, c. a one-piece flexible plastic molded body having (i) a collar portion at each end engaging the circular flat surface of the first and second end plates respectively, said collar portions each having two bosses for receiving fastening means to secure the collars to the first and second end plates respectively, (ii) a notched area to receive the respective lugs, and (iii) a plurality of spaced outwardly bowed ribs interconnecting the collar portions and spanning the space between the first and second end plates, and d. fastening means holding the two bosses of each collar portion together to thereby secure the molded body to the first and second end plates.
Claim 3
Dependent Claim
17 words

Claim 4
Dependent Claim
24 words
The flexible coupling assembly of claim 1 wherein the middle portion of the bowed ribs are thinner than the outer portions of the ribs.
Claim 5
Dependent Claim
54 words
