Abstract
A quick-change mechanism is provided between a male member and a female member which has a socket with an axis. A flange is provided on each member, and in the flange of the female member an eccentric circular cam is pivotably mounted on one side of the socket. The cam may be pivoted through an arc between a locked and an unlocked condition in a single plane. The unlocked condition moves the cam laterally outwardly beyond the cam follower surface in the male member. As the cam is rotated towards the locked condition, the cam locking surface moves in a single plane laterally inwardly and establishes an axially inward force on the cam follower surface. The quick-change mechanism is small and compact and contained entirely within the flange of the female member. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
