  "title": "Distributor cap adaptor for after market distributors",
  "abstract": "A distributor cap adaptor that secures an after market distributor cap adaptor to a distributor. The distributor distributes high voltages to spark plugs in an internal combustion engine. The after market distributor cap having a terminal distance diameter that is 15% greater than a conventional distributor cap. The connection of the after market distributor cap to a body of the distributor cap adaptor provides an improved insulation value that substantially eliminates ignition cross fire in the internal combustion engine.",
  "claims": [
    "1. A distributor cap adaptor to secure an after market distributor cap to a distributor that distributes voltages to spark plugs in an internal combustion engine, the after market distributor cap having an outer diameter and a terminal distance diameter, the terminal distance diameter is approximately 15% greater than a conventional distributor cap, comprising: a substantially cylindrical body providing a base and a top, the body having an outer diameter that decreases relative to an outer diameter of the base in a radial direction toward a central axis to a minimum outer diameter point and increases from the minimum outer diameter point to the top, the body being affixed to the distributor at the base; and a distributor cap register disposed above the top of the body, an outer diameter of the distributor cap adaptor being larger than the outer diameter of the after market distributor cap to receive and connect the after market distributor cap to the body, wherein the connection of the after market distributor cap to the body of the distributor cap adaptor results in an improved insulation value that substantially eliminates the cause of ignition cross fire in the internal combustion engine.",
    "2. The adaptor according to claim 1, wherein the minimum outer diameter point is located approximately midway between the base and top of the adaptor relative to a vertical height of the adaptor.",
    "3. The adaptor according to claim 1, wherein the distributor cap register further comprises a distributor cap index tang to align the after market distributor cap being connected to the adaptor.",
    "4. The adaptor according to claim 1, further comprising at least two spring clip catches disposed on an exterior and below the top of the body of the adaptor.",
    "5. The adaptor according to claim 4, wherein each of the at least two spring catches has a roll pin hole configured to receive a roll pin that securely holds spring clips of the after market distributor cap.",
    "6. The adaptor according to claim 5, wherein the roll pin has a 0.0625 inch diameter.",
    "7. The adaptor according to claim 1, wherein the base further comprises an adaptor register that affixes the adaptor to the distributor, the adaptor register having an outer diameter that is larger than a distributor outer diameter.",
    "8. The adaptor according to claim 1, further comprising at least two through holes designed to receive fasteners there through to affix the adaptor to the distributor.",
    "9. The adaptor according to claim 8, wherein the fasteners are selected from a group including screws and bolts.",
    "10. The adaptor according to claim 1, further comprising a distributor index and computer wiring conduit disposed above the base of the body, the wiring conduit connecting the adaptor to an ignition wire.",
    "11. The adaptor according to claim 1, wherein the body of the adaptor comprises an injection molded plastic.",
    "12. The adaptor according to claim 11, wherein the plastic comprises a thermal plastic having a high dielectric strength that is resistant to harsh engine compartment elements of the internal combustion engine.",
    "13. The adaptor according to claim 12, wherein the harsh engine compartment elements comprise one of the group including oil, fuel, and internal ozone formation.",
    "14. A distributor cap adaptor to secure an after market distributor cap to a distributor that distributes voltages to spark plugs in an internal combustion engine, the after market distributor cap having an outer diameter and a terminal distance diameter, the terminal distance diameter is approximately 15% greater than a conventional distributor cap, comprising: a substantially cylindrical injection molded plastic body having a dielectric strength that is resistant to at least one of oil, fuel and internal ozone formation, the body providing a base and a top, the body having an outer diameter that decreases relative to an outer diameter of the base in a radial direction toward a central axis to a minimum outer diameter point and increases from the minimum outer diameter point to the top, the body being affixed to the distributor at the base; and a distributor cap register disposed above the top of the body, an outer diameter of the distributor cap adaptor being larger than the outer diameter of the after market distributor cap to receive and connect the after market distributor cap to the body, wherein the connection of the after market distributor cap to the body of the distributor cap adaptor results in an improved insulation value that substantially eliminates the cause of ignition cross fire in the internal combustion engine.",
    "15. The adaptor according to claim 14, wherein the minimum outer diameter point is located approximately midway between the base and top of the adaptor relative to a vertical height of the adaptor.",
    "16. The adaptor according to claim 14, wherein the distributor cap register further comprises a distributor cap index tang to align the after market distributor cap being connected to the adaptor.",
    "17. The adaptor according to claim 14, further comprising at least two spring clip catches disposed on an exterior and below the top of the body of the adaptor, wherein each of the at least two spring catches has a roll pin hole configured to receive a roll pin that securely holds spring clips of the after market distributor cap.",
    "18. The adaptor according to claim 14, wherein the base further comprises an adaptor register that affixes the adaptor to the distributor, the adaptor register having an outer diameter that is larger than a distributor outer diameter.",
    "19. The adaptor according to claim 14, further comprising at least two through holes designed to receive fasteners there through to affix the adaptor to the distributor.",
    "20. The adaptor according to claim 1, further comprising a distributor index and computer wiring conduit disposed above the base of the body, the wiring conduit connecting the adaptor to an ignition wire."
