  "title": "Crop gathering belt",
  "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": [
    "1. 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.",
    "2. A crop gathering belt as set forth in claim 1 wherein the longitudinal spacing between lugs is greater than the longitudinal base portion of the lugs.",
    "3. A crop gathering belt as set forth in claim 1 wherein the longitudinally spaced lugs includes two laterally spaced rows of lugs.",
    "4. A crop gathering belt as set forth in claim 3 wherein the lugs of first row are in lateral alignment with the lugs of second row.",
    "5. A crop gathering belt as set forth in claim 3 wherein each row of lugs is arranged near a circumferential edge portion of the belt.",
    "6. A crop gathering belt as set forth in claim 3 wherein the lateral spacing between the rows of lugs is greater than the lateral base portion of the lugs.",
    "7. A crop gathering belt as set forth in claim 1 and further including at least one ply of a generally laterally extending reinforcement of high modulus material disposed between said first and second layer.",
    "8. A crop gathering belt as set forth in claim 1 and further including a third layer of flexible material including a plurality of oriented fibers, said third layer arranged so that the fibers extend generally laterally of the belt, and said third layer disposed between said first and second layers.",
    "9. A crop gathering belt as set forth in claim 1 wherein said second layer is integrally molded with said first layer.",
    "10. A crop gathering belt as set forth in claim 1 wherein said crop engaging portion includes a plurality of longitudinally spaced ribs extending generally laterally of the belt, said ribs having a base width.",
    "11. A crop gathering belt as set forth in claim 10 wherein the longitudinal spacing between ribs is greater than the base width of the ribs.",
    "12. A crop gathering belt as set forth in claim 1 wherein said crop engaging portion includes a plurality of longitudinally spaced ribs extending obliquely of the belt.",
    "13. A crop gathering belt as set forth in claim 1 wherein said crop engaging portion includes a plurality of integrally molded and longitudinally spaced loops extending generally laterally of the belt.",
    "14. A flexible crop gathering belt used in conjunction with at least one toothed pulley, said belt comprising: an intEgrally molded and generally flat body of flexible polymeric material, said body having radially inner and outer surfaces; a tensile section of high modulus material disposed within said flat body; a plurality of integrally molded, longitudinally spaced lugs extending from the radially inner surface, said lugs adapted to mesh with teeth of the pulley; and means projecting from the outer surface for engaging crop to convey crop in association with belt movement.",
    "15. A crop gathering belt as set forth in claim 14 wherein the longitudinally spaced lugs include at least two laterally spaced lug rows, the lugs of one row substantially laterally aligned with the lugs of the second row.",
    "16. A crop gathering belt as set forth in claim 14 wherein said crop gathering means includes a plurality of longitudinally spaced ribs extending generally laterally of the belt.",
    "17. A crop gathering belt as set forth in claim 14 wherein said crop gathering means includes a plurality of integrally molded and longitudinally spaced loops extending generally laterally of the belt.",
    "18. A crop gathering belt as set forth in claim 14 wherein said crop gathering means includes: a generally flat strip of flexible material arranged to define a plurality of longitudinally spaced loops extending generally laterally of the belt; and means for attaching said strip to the radially outer surface.",
    "19. A crop gathering belt as set forth in claim 14 and further including at least one ply of generally laterally aligned reinforcement of high modulus material disposed within said generally flat body."
