  • Patent number: 5615711
    Abstract: An exhaust hose for an internal combustion engine is encase in a screen sleeve. The hose has a metal tube on the inside which can withstand the temperatures of the internal combustion exhaust fumes. The metal tube has ribs which enable it to be bent without kinking, but also provides significant strength to the hose. A thermal insulation layer is placed around the metal tube. The thermal insulation layer may include a gauze wrapping, allowing the inner portion of the thermal insulation layer to breath. The screen sleeve provides an outer layer for the exhaust hose. Preferably the screen sleeve is slightly larger in diameter than the thermally insulated metal tube, such that the screen sleeve fits loosely.

  • Patent number: 5096230
    Abstract: A quick-release adapter for connecting the inlet of an exhaust removal hose to the outlet of a tail pipe of a vehicle with an internal combustion engine while minimizing exhaust leakage. The adapter includes three disk-like permanent magnets pivotably mounted on the inlet of exhaust removal hose and three receptacle-shaped magnetic connectors secured to the outlet of the tail pipe for engaging the magnets and mating the exhaust removal hose to the tail pipe. The exhaust removal hose is thus readily connectable to and disconnectable from the tail pipe.
