Abstract
A jaw for a bar clamp having a trigger pivoted to a handle at a position on the handle that is spaced from the bar. The trigger directly contacting a drive lever at a contact point, such that the contact point between the trigger and the drive lever changes along the length of the drive lever as the trigger pivots with respect to the handle such that when the contact point is remote from the bar the trigger provides high mechanical advantage to the drive lever, and when the contact point is closer to the bar the trigger provides low mechanical advantage to the drive lever. Also, a method of using a bar clamp, including positioning first and second moving jaws on opposite sides of a member to be clamped and activating a mechanical motor to move the bar and force the first moving jaw toward the second moving jaw until both the first and second moving jaws securely clamp the first member to be clamped between the first and second moving jaws.
