Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
78 words
A tire bead core ring for being embedded within the bead of a tire to extend around the circumference of the bead, comprising, in combination: a. a plurality of cable rings, said rings being of relatively differing annular diameters in the direction of the bead circumference; and b. at least one layer of helically wound endless wire encasing said plurality of cable rings and maintaining said plurality of cable rings in supporting and force-transmitting relationship with each other.
Claim 2
Dependent Claim
78 words
A tire bead core ring for being embedded within the bead of a tire to extend around the circumference of the bead, comprising, in combination: a. a plurality of cable rings, said rings being of relatively differing annular diameters in the direction of the bead circumference; and b. at least one layer of helically wound endless wire encasing said plurality of cable rings and maintaining said plurality of cable rings in supporting and force-transmitting relationship with each other.
Claim 3
Dependent Claim
32 words
The bead core ring of claim 1, wherein said plurality of cable rings comprise an endless wire ring stem and at least one layer of a helically wound endless wire concentric therewith.
Claim 4
Dependent Claim
19 words
The bead core ring of claim 1, wherein said plurality of cable rings are of equal ring cross-sectional diameter.
Claim 5
Dependent Claim

Claim 7
Dependent Claim
108 words
A tire bead core ring for being embedded within the bead of a tire to extend around the circumference of the bead, comprising in combination: a. a spacer ring having an approximately rectangular cross-section; b. at least two endless cable rings concentrically disposed with respect to the axis of rotation of a tire, said rings being of different annular diameters in the direction of the bead circumference; and c. at least one layer of helically wound endless wire encasing said at least two endless cable rings and said spacer ring and maintaining said at least two endless cable rings in supporting and force-transmitting relationship wiTh said spacer ring.
Claim 8
Dependent Claim
108 words
A tire bead core ring for being embedded within the bead of a tire to extend around the circumference of the bead, comprising in combination: a. a spacer ring having an approximately rectangular cross-section; b. at least two endless cable rings concentrically disposed with respect to the axis of rotation of a tire, said rings being of different annular diameters in the direction of the bead circumference; and c. at least one layer of helically wound endless wire encasing said at least two endless cable rings and said spacer ring and maintaining said at least two endless cable rings in supporting and force-transmitting relationship wiTh said spacer ring.
Claim 9
Dependent Claim
17 words
The bead core ring of claim 6, wherein said cable rings are of equal ring cross-sectional diameter.
Claim 10
Dependent Claim
18 words
The bead core ring of claim 6, wherein said cable rings are of relatively differing ring cross-sectional diameter.
Claim 11
Dependent Claim
33 words
The tire bead core ring of claim 6, wherein the spacer ring has an approximately rectangular longitudinal cross-section and wherein said cable rings are supported along the longitudinal sides of the spacer ring.
Claim 12
Dependent Claim
25 words

Claim 14
Dependent Claim
37 words
The tire bead core ring of claim 6, wherein the radius of curvature of the longitudinal sides of the spacer ring is equal to or greater than one-half the diameter of a wire of a cable ring.
Claim 15
Dependent Claim
30 words
The tire bead core ring of claim 6, wherein the sides of the spacer ring which face the cable rings are concave and the cable rings engage said concave sides.
Claim 16
Dependent Claim
170 words
The tire bead core ring of claim 6, wherein said cable rings each comprise an endless wire ring stem and a plurality of layers of helically wound endless wires concentric therewith, the wire cross-sectional diameter of said endless wire ring stem is preferably about twice as large as the wire cross-sectional diameter of said wires comprising said helically wound endless wires concentric therewith, and wherein the thickness of said spacer ring approximately corresponds to the cross-sectional diameter of said helically wound endless wires concentric therewith, and wherein there are two layers of helically wound endless wires which firmly encase the spacer ring and said at least two endless cable rings, the cross-sectional diameter of the wire of said layers of helically wound endless wires encasing the spacer ring and said at least two endless cable rings approximately corresponds to the cross-sectional diameter of the helically wound endless wires which are concentric with said endless wire ring stem, said wire layers being wound with oppositely directed pitch from layer to layer.
