  "title": "Attachment for exhaust pipe",
  "abstract": "An attachment for an exhaust pipe. A rolled bead of the exhaust pipe is formed on its outer periphery providing a seal with a turbo-charger outlet flange and a clamp ring bolted around the bead. The exhaust pipe is adapted for supporting the muffler.",
  "claims": [
    "1. An exhaust system for an internal combustion engine comprising, a supporting conduit member including a peripheral flange defining an edge having essentially a cross-sectional configuration of 90°, an exhaust pipe received in said conduit member and including a deformable peripheral bead, an adjoining portion of said exhaust pipe joining said bead to the cylindrical portion of said exhaust pipe defining a curvature forming a radius, an aligning external peripheral surface on said exhaust pipe bearing against the inner peripheral surface of said conduit member, a clamping ring embracing said exhaust pipe engaging said peripheral bead, fastening means clamping said peripheral flange and said clamping ring against opposing sides of said peripheral bead and pressing said edge of said flange firmly against said adjoining portion to form a sealed coupling between said support member and said exhaust pipe.",
    "2. An exhaust system for an internal combustion engine as set forth in claim 1 wherein said exhaust pipe includes a steel pipe forming a hollow bead.",
    "3. An exhaust system for an internal combustion engine as set forth in claim 1 wherein said peripheral bead on said exhaust pipe comprises a rolled bead rolled externally from the inside of said pipe to form a peripheral bead of larger diameter on the external diameter of said exhaust pipe.",
    "4. An exhaust system for an internal combustion engine as set forth in claim 1 wherein said supporting conduit member includes a discharge conduit on a supercharger.",
    "5. An exhaust system for an internal combustion engine as set forth in claim 1 including a muffler mounted on said exhaust pipe.",
    "6. An exhaust system for an internal combustion engine as set forth in claim 1 wherein said fastening means includes clamping bolts.",
    "7. An exhaust system for an internal combustion engine as set forth in claim 1 wherein said exhaust pipe defines an elbow.",
    "8. An exhaust system for an external combustion engine as set forth in claim 1 wherein said flange defines a radial flange, said clamping ring defines a radial facing, said fastening means thereby presses said radial flange and said radial facing of said clamping ring against the peripheral bead of said exhaust pipe to partially deform said bead and form seal integrity.",
    "9. An exhaust system for an internal combustion engine as set forth in claim 1 wherein said conduit member includes a supercharger discharge conduit, said exhaust pipe defines a steel pipe forming a hollow peripheral raised bead on its external periphery, said clamping ring defines a radial facing for pressing against the side of said peripheral bead, fastening means defines a plurality of bolts for pressing said flange and said clamping ring firmly against said bead to slightly deform said bead and form seal integrity."
