Abstract
A jaw assembly for a jaw chuck for holding a workpiece to the spindle of a machine, such as a lathe, includes an intermediate coupling member that engages a master jaw slot formed in a master jaw which is disposed in a radial guide formed in the body of the chuck. A retaining mechanism secures the intermediate coupling member within the master jaw slot. A top jaw is configured to be connectively engaged with the intermediate coupling member by inserting the intermediate coupling member into a top jaw slot. The top jaw is held securely to the intermediate coupling member, and, accordingly, to the master jaw, when the retaining mechanism is tightened. During top jaw change-out the retaining mechanism is released, thereby permitting the top jaw to be disengaged from the intermediate coupling member while still loosely retaining the intermediate coupling member within the master jaw slot. A new top jaw is installed by merely engaging it with the intermediate coupling member and then re-tightening the retaining mechanism.
