Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
A torque transmitting device for operably coupling end-to-end two rotatable members having generally parallel axes of rotation shiftable relative to one another, said device including: a plurality of linkages disposed between and interconnecting the adjacent ends of said members, each of said linkages comprising a central link and a first and second connecting link respectively, pivotally mounted on opposite ends of said central link; first means pivotally securing said first connecting links to one of said members; second means pivotally securing said second connecting links to the other of said members; and means coupling said central links intermediate the ends thereof for relative swinging movement of the central links about an axis extending substantially parallel to said axes of rotation.
Claim 2
Dependent Claim
120 words
A torque transmitting device for operably coupling end-to-end two rotatable members having generally parallel axes of rotation shiftable relative to one another, said device including: a plurality of linkages disposed between and interconnecting the adjacent ends of said members, each of said linkages comprising a central link and a first and second connecting link respectively, pivotally mounted on opposite ends of said central link; first means pivotally securing said first connecting links to one of said members; second means pivotally securing said second connecting links to the other of said members; and means coupling said central links intermediate the ends thereof for relative swinging movement of the central links about an axis extending substantially parallel to said axes of rotation.
Claim 3
Dependent Claim
16 words
A torque transmitting device as claimed in claim 1, there being three linkages interconnecting said members.
Claim 4
Dependent Claim
18 words
A torque transmitting device as claimed in claim 2, wherein said central links are substantially equal in length.
Claim 5
Dependent Claim
18 words
A torque transmitting device as claimed in claim 3, wherein said connecting links are substantially equal in length.
Claim 6
Dependent Claim
43 words
A torque transmitting device as claimed in claim 4, wherein said first and second securing means each include three pivots angularly spaced on a respective member about the axis of rotation thereof, each of said pivots being associated with a respective connecting link.
Claim 7
Dependent Claim
19 words
A torque transmitting device as claimed in claim 5, wherein said pivots are equidistant from respective axes of rotation.
Claim 8
Dependent Claim
26 words
A torque transmitting device as claimed in claim 6, wherein the angular spacing between two of said pivots in each of said securing means is 90°.
Claim 9
Dependent Claim
26 words
A torque transmitting device as claimed in claim 7, wherein the third pivot in each of said securing means is spaced 135° from said two pivots.
Claim 10
Dependent Claim
20 words
A torque transmitting device as claimed in claim 1, wherein said coupling means interconnects the midpoints of said central links.
Claim 11
Dependent Claim
31 words
A torque transmitting device as claimed in claim 9, wherein the spacing between said pivots and respective said axes of rotation is equal to one-half the length of said central links.
