Claim:
A cam assembly for adjusting a pair of locking pliers, said locking pliers having a first assembly having an elongated first handle member and a first jaw member, a second jaw member, an elongated second handle assembly, and a link assembly having at least one link, said second jaw member pivotally coupled to said first jaw member so that the jaw members may move between an open position and a closed position, said second handle assembly pivotally coupled to said second jaw member, said at least one link coupled to said first handle member and said second jaw member, wherein the proximity of said at least one link to the distal end of said first handle member affects the spacing of said jaw members, said cam assembly comprising: a trolley structured to be slidably coupled to said first handle member, said trolley having a cam follower and structured to be coupled to said at least one link; a cam having a disk-like body with a radially extending handle; said cam rotatably coupled to said first assembly first handle member and structured to engage said trolley cam follower; wherein, when in said jaw members are in said open position and when said at least one link is coupled to said trolley, rotation of said cam causes the position of said jaw members to change; wherein said cam has a radial surface with a plurality of flats, each flat disposed at a different radial distance from the axis of said cam body; wherein the radii of the flats increases/decreases in series; said plurality of flats includes a first flat, a second flat, a third flat, and a fourth flat; said first flat having a radius of between about 0.18 and 0.22 inch; and wherein each successive flat has a radius that is about 0.02 inches further from the axis than the prior flat.
