Abstract
Abstract A compound rod-reinforced belt in which spirals of one twist are interwoven and rods are inserted at least through each interlocked juncture of helix vertices, there being at least three rods passing transversely through each spiral with the spacing between two adjacent rods being approximately one-half the spacing between all other adjacent rods.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
134 words
A compound rod-reinforced belt comprising: a plurality of elongated spirals of the same twist, the vertices of each spiral interlocking with the vertices of an adjacent spiral so that adjacent, interlocking, facing vertices define transversely aligned pockets through which A rod is adapted to be inserted; and a plurality of rods interfitted with the spirals, one rod being inserted through each group of transversely aligned pockets and at least three rods passing through each spiral, the two rods passing through and engaging the vertices of each spiral being the bearing rods of said spiral and all other rods passing through said spiral being the nonbearing rods of said spiral, the spacing between two of the rods passing through each spiral being approximately one-half the spacing between all other adjacent rods passing through each spiral.
Claim 2
Dependent Claim
134 words
A compound rod-reinforced belt comprising: a plurality of elongated spirals of the same twist, the vertices of each spiral interlocking with the vertices of an adjacent spiral so that adjacent, interlocking, facing vertices define transversely aligned pockets through which A rod is adapted to be inserted; and a plurality of rods interfitted with the spirals, one rod being inserted through each group of transversely aligned pockets and at least three rods passing through each spiral, the two rods passing through and engaging the vertices of each spiral being the bearing rods of said spiral and all other rods passing through said spiral being the nonbearing rods of said spiral, the spacing between two of the rods passing through each spiral being approximately one-half the spacing between all other adjacent rods passing through each spiral.
Claim 3
Dependent Claim
32 words
The compound rod-reinforced belt as defined in claim 1 wherein the smaller spacing is equal to or greater than the spiral diameter and the larger spacing is approximately double the smaller spacing.
Claim 4
Dependent Claim
114 words

Claim 7
Dependent Claim
49 words
The compound rod-reinforced belt as defined in claim 1 wherein each spiral is transversely contiguous with at least one additional spiral and longitudinally displaced with respect to the transversely contiguous spiral by a distance at least as great as the sum of two spiral diameters plus one rod diameter.
Claim 8
Dependent Claim
47 words
The compound rod-reinforced belt as defined in claim 1 wherein each spiral is transversely contiguous with at least one additional spiral and longitudinally displaced with respect to the transversely contiguous spiral by a distance approximately equal to the sum of two spiral diameters plus one rod diameter.
Claim 9
Dependent Claim
49 words
The compound rod-reinforced belt as defined in claim 1 wherein each spiral is transversely contiguous with at least one additional spiral and longitudinally displaced with respect to the transversely contiguous spiral by a distance at least as great as the sum of two spiral diameters plus one rod diameter.
Claim 10
Dependent Claim
115 words
The compound rod-reinforced belt as defined in claim 1 wherein each spiral has a minimum projected helix angle theta defined by the centerline of the belt and the centerline of the substantially straight centerline leg of the spiral, the sine of which is at least as great as one given by the equation and wherein each spiral has a minimum pitch from bearing rod center to bearing rod center at least as great as one given by the equation y a + b, where 4 minimum pitch a (total number of rods passing through each spiral - 1) multiplied by (rod diameter) b (number of nonbearing rods X 2 plus 1) multiplied by (spiral diameter).
Claim 11
Dependent Claim
33 words
The compound rod-reinforced belt as defined in claim 9 wherein each spiral has a pitch at least as great as one given by the equation y 2 rod diameters plus 3 spiral diameters
Claim 12
Dependent Claim
33 words
The compound rod-reinforced belt as defined in claim 9 wherein each spiral has a pitch at least as great as one givEn by the equation y 3 rod diameters plus 5 spiral diameters
Claim 13
Dependent Claim
49 words
The compound rod-reinforced belt as defined in claim 9 wherein each spiral is transversely contiguous with at least one additional spiral and longitudinally displaced with respect to the transversely contiguous spiral by a distance at least as great as the sum of two spiral diameters plus one rod diameter.
