DEFINITION

Classification: 187/368

With eccentric camming face:

(under subclass 367) Retaining, halting, or retarding means wherein the engaging part is provided with a curved engaging periphery and the axis about which the engaging part swings is positioned in such a manner that it is not geometrically centered relative to the engaging periphery of the part which arrangement causes the periphery to apply ever increasing pressure to the fixed structure it engages as the part swings toward its final position.
