Abstract
Abstract Endless means for conveying employing juxtaposed facing belts, each belt including two generally parallel layers of flexible material sandwiched tensile section. The belt is adapted for use with toothed pulleys. A plurality of longitudinally spaced lugs extend from one layer to be meshable with teeth of a pulley and a plurality of longitudinally spaced crop engaging members extend from the second layer.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
113 words
A flexible crop gathering belt used in conjunction with at least one toothed pulley, said belt capable of cooperating with an oppositely facing endless belt to engage and gather crop including that of the cornstalk type, said belt comprising: a first layer of flexible material extending longitudinally of the belt to define a driving portion thereof including a plurality of longitudinally spaced lugs adapted to mesh with teeth of the pulley, said lugs having a base portion; a second layer of flexible material spaced from and generally parallel to said first layer to define a crop engaging portion, and; a tensile section of high modulus material disposed between said first and second layers.
Claim 2
Dependent Claim
113 words
A flexible crop gathering belt used in conjunction with at least one toothed pulley, said belt capable of cooperating with an oppositely facing endless belt to engage and gather crop including that of the cornstalk type, said belt comprising: a first layer of flexible material extending longitudinally of the belt to define a driving portion thereof including a plurality of longitudinally spaced lugs adapted to mesh with teeth of the pulley, said lugs having a base portion; a second layer of flexible material spaced from and generally parallel to said first layer to define a crop engaging portion, and; a tensile section of high modulus material disposed between said first and second layers.
