Patent number: 8413970Abstract: A pin clamp assembly having a body, a locating pin, an actuator, a drive rod, a cam, and a finger is provided. The locating pin is coupled to the body and movable between extended and retracted positions. The drive rod is movable relative to the locating pin. The cam is movable relative to the locating pin and the drive rod. The finger is coupled to the drive rod and movable between extended and retracted positions. Actuation of the actuator causes the drive rod to move which extends the finger without moving the locating pin. Also, continued retraction of the drive rod after the finger has extended causes the cam to move out from the slot in the body to allow the locating pin to retract.Type: GrantFiled: June 19, 2008Date of Patent: April 9, 2013Assignee: PHD, Inc.Inventor: Bruce D. McIntosh
