    Patent number: 4964193
    Abstract: The hinge has two leaves with interengaging knuckles. A plastic coated metal hinge pin extends through the knuckles and the knuckles are crimped onto the plastic coated hinge pin. The tighter the knuckles grip the pin the more the plastic is deformed and the greater will be the torque required to operate the hinge. The plastic is extruded onto the pin to bond the plastic to the pin.
