  "abstract": "A seal system and method for a bolted track such as a baking system conveyor track. The seal system provides a seal between a pair of track pieces being coupled end-to-end to one another. The seal system includes flanges attached near the ends of the track pieces and a gasket compressed between the flanges when the track pieces are coupled to form a seal. In example embodiments, the gasket is attached to a track plate. The track plate is coupled between the flanges and is configured to shield the gasket from heat and direct flame. The seal system optionally also includes a joint cover affixed to the bottom of the coupled flanges to form a secondary seal.",
  "claims": [
    "1. A seal system for coupling first and second track pieces of a conveyor system, the seal system comprising: a first flange attached adjacent to an end of the first track piece and extending transversely therefrom, and a second flange attached adjacent to an end of the second track piece and extending transversely therefrom, the first and second flanges configured for bolting to one another to join the first track piece to the second track piece with a seam between the first and second track pieces; and a track support plate having a cutout formed therein, and a sealing gasket positioned within the cutout of the track support plate, whereby the track support plate is configured to be engaged between the first and second flanges with the sealing gasket compressed between the first and second flanges and forming a seal around at least a portion of the seam between the first and second track pieces when the first and second flanges are bolted together with the track support plate engaged therebetween.",
    "2. The seal system of claim 1, wherein the gasket defines a generally U-shaped cross-sectional profile and comprises a raised ridge protruding outwardly from first and second ends of the gasket for sealing engagement with the first and second flanges when the first and second flanges are bolted together.",
    "3. The seal system of claim 1, wherein the first and second flanges each include one or more holes for receiving bolts to connect the first and second flanges together.",
    "4. The seal system of claim 3, wherein the one or more holes in the first flange are configured to align with the one or more holes in the second flange when the first and second flanges are bolted together.",
    "5. The seal system of claim 4, wherein the track support plate also includes one or more holes configured to align with the one or more holes in each of the first and second flanges when the first and second flanges are bolted together.",
    "6. The seal system of claim 1 further comprising a joint cover including a bottom plate and a side wall extending from at least a portion of a periphery of the bottom plate.",
    "7. The seal system of claim 6, wherein the joint cover is coupled to at least one of the first and second flanges such that the bottom plate covers a bottom of each of the flanges.",
    "8. The seal system of claim 7, wherein the joint cover further comprises an adhesive substance between a top of the bottom plate and the bottom of the flanges.",
    "9. A seal system for coupling first and second track pieces in a modular conveyor system, the seal system comprising: a track plate having a cutout formed therein, and a gasket positioned within the cutout of the track plate; and a first flange extending transversely from an end of the first track piece, and a second flange extending transversely from an end of the second track piece, the first and second flanges each comprising a plurality of bolt holes configured for alignment to receive bolts to link the first and second track pieces to one another with a seam formed between the ends of the first and second track pieces; wherein the track plate is held between the first and second flanges when the first and second track pieces are linked, and wherein the gasket forms a seal at least partially around the seam between the ends of the first and second track pieces when the bolts are engaged between the first and second flanges.",
    "10. The seal system of claim 9, wherein the gasket defines a generally U-shaped cross-sectional profile and comprises a raised ridge protruding outwardly from first and second ends of the gasket for sealing engagement with the first and second flanges when the bolts are engaged between the first and second flanges.",
    "11. The seal system of claim 9 further comprising a joint cover including a bottom plate and a side wall extending from at least a portion of a periphery of the bottom plate.",
    "12. The seal system of claim 11, wherein the joint cover is coupled to the flanges such that the bottom plate covers a bottom of each of the flanges.",
    "13. The seal system of claim 12, wherein the joint cover further comprises an adhesive substance between a top of the bottom plate and the bottom of the flanges.",
    "14. The seal system of claim 9, wherein the track plate is capable of interacting with a portion of the modular conveyor system.",
    "15. A modular conveyor and seal system comprising: a first track piece and a second track piece; a first flange extending from the first track piece, and a second flange extending from the second track piece; a track support member having a cutout; and a gasket positioned within the cutout of the track support member; wherein the first flange and the second flange are configured for coupling the first track piece to the second track piece, with the track support member engaged between the first flange and the second flange and the gasket forming a seal between the first flange and the second flange.",
    "16. The modular conveyor and seal system of claim 15, wherein the gasket defines a generally U-shaped cross-sectional profile and comprises a raised ridge protruding outwardly from first and second ends of the gasket for sealing engagement with the first and second flanges.",
    "17. The modular conveyor and seal system of claim 15, further comprising a joint cover including a bottom plate and a side wall extending from at least a portion of a periphery of the bottom plate.",
    "18. The modular conveyor and seal system of claim 17, wherein the joint cover extends beneath the first and second flanges.",
    "19. The modular conveyor and seal system of claim 17, wherein the joint cover contains a caulk material forming a secondary seal around the first and second track pieces."

  "description_excerpt": "The present invention relates generally to the field of commercial baking equipment, and more particularly to a seal system and method for a bolted track used in conveyorized backing ovens.\n\nCommercial baking systems often use a continuous conveyor track to move products through the different baking apparatuses such as proofers and ovens in a baking system. The continuous conveyor track can be constructed from a modular track system. The track is commonly constructed from a series of track pieces coupled end to end to form the desired track shape. The track pieces are typically directly coupled together, usually by welding each track piece together, end-to-end. However, this process can be time consuming and suffer from issues with quality. Further, welding the track pieces together may make it hard to change or replace track pieces after the initial construction. As a result, a bolted track system has been developed wherein the track pieces are bolted to one another, instead of welded, end-to-end.\n\nIn the bolted track system, a flange is typically attached to each end of the individual track pieces. The flanges of each track piece can be bolted or fastened to one another using a variety of attachment methods. Often, the flanges of each track piece are attached to a track support beam designed to support the track above a support surface. Caulk may be applied between the flanges and the track support to create a seal. While the bolted track system may be considered an improvement over the direct attachment track system, it can still suffer from issues including leaks.",
