20080276766 | Locking Pliers with CAM - A pair of locking pliers having an adjusting device that utilizes a cam assembly. The pliers, preferably, include a trolley disposed in a first handle member that defines a channel. The trolley is structured to be coupled to a link assembly wherein the position of the link assembly relative to the distal end of the first handle member affects the spacing of the pliers' jaws. The cam assembly is, preferably, a planar disk-like body having a radially extending handle and, preferably, a plurality of flats about the circumference. The cam assembly is disposed, preferably, in the plane defined by the first handle member and the second handle assembly. The cam is coupled to the first handle member at the distal end of the handle portion and its' axis extends generally perpendicular to the plane defined by the first handle member and the second handle assembly. At this location, the cam plurality of flats are structured to engage the trolley/cam follower as the cam handle extends beyond the first handle member distal end. Rotation of the cam causes the trolley, and therefore link assembly, to move relative to the distal end of the first handle member. | 11-13-2008 |

20080223184 | Locking pliers with offset jaws - A hand tools similar in design to the commonly known locking pliers. The present invention includes an offset in the jaw, placing them in a separate but parallel plane to the plane of both the handles.
