  • Patent number: 4366842
    Abstract: A large diameter suction and discharge hose capable of withstanding compressive end loads is formed of reinforced elastomeric material and includes a fitting at each end comprising a flange butt connected to a cylindrical nipple. The nipple includes an area of reduced outside diameter between its flange and opposite end to aid in retention of the nipple to the hose. The inner tube and inner reinforcing plies extend through the bore of the fitting and are adhered to the end face of the flange of the fitting. Intermediate reinforcing plies extend over the cylindrical nipple and are forceably retained by anchoring means which extend over annular grooves provided in the fitting. A helically wound heavy gauge wire extends between the back faces of the flanges and is embedded in elastomeric material. At least one outer ply layer is provided over the helically wound heavy gauge wire. An outer cover layer of elastomeric material completes the hose. A method of making such hose is also described.
