Abstract

An apparatus for testing a tire is disclosed. The apparatus includes an improved test probe. The apparatus comprising a support frame, first and second rollers connected to the support frame and arranged to support to support a crown portion of the tire, a probe having a support bracket for receiving a section of chains. The section of chains is comprised of a plurality of first chain members, wherein the first chain members extend in a first direction. Preferably, the first chain members are oriented in parallel relation with respect to each other. The first direction is preferably in the vertical direction. The section of chains further includes at least one cross chain member which contacts or interlinks or joins with each first chain member. The section of chains may also comprise chainmail. The section of chains or chainmail is positioned in the tire and is in electrical communication with a first electrode, wherein one of said rollers is a second electrode, and a power supply in electrical communication with the first and second electrode in order to created a electric potential between the first and second electrode.

Claims

1. An apparatus for testing a tire, the tire having opposed sidewalls joined together by a crown section, the crown section having an inner surface and an outer surface, the apparatus comprising a support frame, first and second rollers connected to the support frame and arranged to support to support a crown portion of the tire, a probe having a support bracket for receiving a section of chainmail therein, wherein the chainmail is positioned in the tire, wherein the chainmail section is in electrical communication with a first electrode, wherein one of said rollers is a second electrode, and a power supply in electrical communication with the first and second electrode in order to create an electric potential between the first and second electrode.

2. The apparatus of claim 1 wherein the chainmail section has a length in the range of 3 to 15 inches.

3. The apparatus of claim 1 wherein the chainmail section has a width in the range of 2 to 15 inches.

4. The apparatus of claim 1 wherein the chainmail section is formed from a plurality of interlinking circles.

5. The apparatus of claim 1 wherein the chainmail section has a density in the range of 3 to 200 circles per inch.

6. An apparatus for testing a tire, the tire having opposed sidewalls joined together by a crown section, the crown section having an inner surface and an outer surface, the apparatus comprising a support frame, first and second rollers connected to the support frame and arranged to support to support a crown portion of the tire, a probe having a support bracket for receiving a section of chains therein, wherein the section of chains is comprised of a plurality of a first chain member extending in a first direction, wherein each first chain member is in contact with at least one cross chain member, wherein the section of chains is positioned in the tire and in electrical communication with a first electrode, wherein one of said rollers is a second electrode, and a power supply in electrical communication with the first and second electrode in order to create an electric potential between the first and second electrode.

7. The apparatus of claim 6 wherein the first chain members are oriented in parallel relation with respect to each other.

8. The apparatus of claim 6 wherein the first chain members are oriented in the vertical direction.

9. The apparatus of claim 6 wherein the at least one cross member is joined to each first chain member.

10. The apparatus of claim 6 wherein there are at least two cross-chain members.

11. The apparatus of claim 6 wherein the cross-chain members are oriented in a ninety degree direction transverse to the direction of the first chain members.

12. An electrode probe useful for testing a tire, the tire having opposed sidewalls joined together by a crown section, the crown section having an inner surface and an outer surface, the apparatus comprising a support frame, first and second rollers connected to the support frame and arranged to support to support a crown portion of the tire, a probe having a support bracket for receiving a section of chainmail therein, wherein the chainmail is positioned in the tire, wherein the chainmail section is in electrical communication with a first electrode, wherein one of said rollers is a second electrode, and a power supply in electrical communication with the first and second electrode in order to create an electric potential between the first and second electrode.

13. An electrode probe useful for testing a tire, the tire having opposed sidewalls joined together by a crown section, the crown section having an inner surface and an outer surface, the apparatus comprising a support frame, first and second rollers connected to the support frame and arranged to support to support a crown portion of the tire, a probe having a support bracket for receiving a section of chains therein, wherein the section of chains is positioned in the tire and is in electrical communication with a first electrode, wherein the section of chains is comprised of a plurality of a first chain member extending in a first direction, wherein each first chain member is in contact with at least one cross chain member, wherein one of said rollers is a second electrode, and a power supply in electrical communication with the first and second electrode in order to create an electric potential between the first and second electrode.
