Heat-resistant protective cover for a drive axle joint seal

Claim 2

A heat-resistant sock for enclosing a mechanical joint connecting first and second elongated members, wherein said first and second members are moveable relative to one another and said joint is enclosed within an elongated boot connected at one end to the first member and connected at another end to the second member, the sock comprising: an elongated enclosure generally complementary to a shape of the boot and enclosing the boot, the enclosure having first and second surfaces defining apertures at first and second ends respectively engaging the first and second members, the enclosure having an outer insulating layer, a central fiber layer capable of withstanding exposure to temperatures up to 500° F. and an inner lubricating layer facing the boot; and releasable attaching means for clamping the first and second ends of the enclosure to the first and second members respectively.

Claim 3

The sock of claim 1 further comprising: the elongated enclosure formed of flexible fabric material loosely draped about the boot allowing unfettered normal movement of the first and second members relative to one another.

Claim 4

The sock of claim 1 further comprising: means defining an opening extending from the first end of the elongated enclosure longitudinally to the second end of the elongated enclosure allowing installation of the elongated enclosure over the boot in a radial direction with respect to the first and second members.

Claim 5

The sock of claim 1 further comprising: the releasable attaching means for clamping the first and second ends of the enclosure to the first and second members respectively spaced longitudinally from corresponding ends of the boot.

Claim 6

The sock of claim 1 further comprising: the elongated enclosure generally conforming to an exterior contour of the boot.

Claim 7

The sock of claim 1 further comprising: the outer insulating layer capable of reflecting heat away from the elongated enclosure.

Claim 8

A heat-resistant sock for enclosing a mechanical joint connecting first and second elongated members, wherein said first and second members are moveable relative to one another and said joint is enclosed within an elongated boot connected at one end to the first member and connected at another end to the second member, the sock comprising: an elongated enclosure formed of a flexible fabric material loosely draped about the boot allowing unfettered normal movement of the first and second members relative to one another, the elongated enclosure generally conforming to an exterior contour of the boot and generally complementary to a shape of the boot, the elongated enclosure enclosing the boot and having first and second surfaces defining apertures at first and second ends respectively engaging the first and second members, the elongated enclosure including means defining an opening extending from the first end of the elongated enclosure longitudinally to the second end of the elongated enclosure allowing installation of the elongated enclosure over the boot in a radial direction with respect to the first and second members, the elongated enclosure having an outer insulating layer capable of reflecting heat away from the elongated enclosure, a central fiber layer capable of withstanding exposure to temperatures up to 500° F. and an inner lubricating layer facing the boot; and releasable attaching means for clamping the first and second ends of the elongated enclosure to the first and second members respectively spaced longitudinally from corresponding ends of the boot.

Claim 9

A heat-resistant sock for enclosing a mechanical joint connecting first and second elongated members, wherein said first and second members are moveable relative to one another and said joint is enclosed within an elongated boot connected at one end to the first member and connected at another end to the second member, the sock comprising: an elongated enclosure formed of a flexible fabric material loosely draped about the boot allowing unfettered normal movement of the first and second members relative to one another, the elongated enclosure generally conforming to an exterior contour of the boot and generally complementary to a shape of the boot, the elongated enclosure enclosing the boot and having first and second surfaces defining apertures at first and second ends respectively engaging the first and second members, the elongated enclosure including means defining an opening extending from the first end of the elongated enclosure longitudinally to the second end of the elongated enclosure allowing installation of the elongated enclosure over the boot in a radial direction with respect to the first and second members, the elongated enclosure having an outer insulating layer capable of reflecting heat away from the elongated enclosure, a central fiber layer capable of withstanding exposure to temperatures up to 500° F. and an inner lubricating layer facing the boot; and releasable attaching means for clamping the first and second ends of the elongated enclosure to the first and second members respectively spaced longitudinally from corresponding ends of the boot.
