Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
97 words
A device of the class described, comprising a rotatable shaft member, a plurality of supporting members spaced from said shaft member and from each other, a plurality of conjointly movable rocker members, one of which is interposed between each of said supporting members and said shaft member, and flexible motiontransmitting band means secured under tension to and extending between a pair of supporting members, said band means being arranged to partially encompass said shaft member and the rocker members interposed between each of said pair of supporting members and said shaft member in a generally sinuous fashion.
Claim 2
Independent Claim
97 words
A device of the class described, comprising a rotatable shaft member, a plurality of supporting members spaced from said shaft member and from each other, a plurality of conjointly movable rocker members, one of which is interposed between each of said supporting members and said shaft member, and flexible motiontransmitting band means secured under tension to and extending between a pair of supporting members, said band means being arranged to partially encompass said shaft member and the rocker members interposed between each of said pair of supporting members and said shaft member in a generally sinuous fashion.
Claim 3
Dependent Claim
27 words
The structure, as defined in claim 1, wherein Each of said rocker members includes a surface which mates with a surface on the supporting member associated therewith.
Claim 4
Dependent Claim

The structure, as defined in claim 2, wherein one of the mating surfaces of said rocker and supporting members is convex.
Claim 5
Dependent Claim
22 words
The structure, as defined in claim 3, wherein the other of the mating surfaces of said rocker and supporting members is flat.
Claim 6
Dependent Claim
43 words
The structure, as defined in claim 1, wherein each of said rocker members includes two surfaces, one of which mates with a surface on said shaft member and and the other of which mates with a surface on the supporting member associated therewith.
Claim 7
Dependent Claim
19 words
The structure, as defined in claim 5, wherein both of the mating surfaces of each rocker member are convex.
Claim 8
Dependent Claim
21 words
The structure, as defined in claim 1, wherein said supporting members are spaced from said shaft member and from each other.
Claim 9
Dependent Claim
23 words
The structure, as defined in claim 7, wherein said band means is secured to and extends between each pair of adjacent supporting members.
Claim 10
Dependent Claim
22 words
The structure, as defined in claim 8, which includes first, second, and third supporting members and first, second, and third rocker members.
Claim 11
Dependent Claim
121 words
The structure, as defined in claim 9, wherein said band means comprises fist, second, and third band sections, the first of which is secured to said first and second supporting members and is arranged to partially encompass said shaft member and said first and second rocker members in a generally sinuous fashion, the second of which is secured to said second and third supporting members and is arranged to partially encompass said shaft member and said second and third rocker members in a generally sinuous fashion, and the third of which is secured to said third and first supporting members and is arranged to partially encompass said shaft member and said third and first rocker members in a generally sinuous fashion.
Claim 12
Dependent Claim
22 words
The structure, as defined in claim 10, wherein said band means is a continuous single piece construction which includes said three sections.
Claim 13
Dependent Claim
97 words
The structure, as defined in claim 11, wherein said first band section comprises a first strip for aligning and constraining the motion of said first and second rocker members, said second band section comprises second and third strips which are symmetrically spaced from said first strip for aligning and constraining the motion of said second and third rocker members, and said third band section comprises fourth and fifth strips which are symmetrically spaced from said first strip and from said second and third strips for aligning and constraining the motion of said third and first rocker members.
Claim 14
Dependent Claim
32 words
The structure, as defined in claim 12, which includes resilient means operatively connected to each of said supporting members and the band section secured thereto for maintaining said band section under tension.
Claim 15
Dependent Claim
44 words
The structure, as defined in claim 13, which includes input means operatively connected to one of said rocker members for causing conjoint rolling of all of said rocker members on said support members and consequent rotation of said shaft member about a fixed axis.
