20080282851 | LOCKING PLIERS - The locking pliers comprises a first handle connected to a first jaw. A second handle and second jaw are pivotably connected to the first handle and first jaw such that movement of the first handle relative to the second handle causes the jaws to open and close. A mechanism is provided to lock the jaws relative to one another and apply a clamping or gripping force on a workpiece positioned between the jaws. A release mechanism is provided to unlock the pliers that is independent of the locking operation. | 11-20-2008 |
20100018361 | LOCKING PLIERS - The pliers comprise a fixed assembly and a second jaw movable relative to the first jaw between an open position and a closed, locked position. A movable pivot connects the second jaw to the fixed assembly such that the movable pivot can move relative to the fixed assembly when the second jaw is in the closed, locked position and a torque is applied to the pliers. The second jaw is configured such that a resultant force on the second jaw is inside of the fixed pivot, between the fixed pivot and the movable pivot. | 01-28-2010 |
20100018362 | LOCKING PLIERS - A lockable pliers comprises a fixed assembly comprising a first handle supporting a first jaw. A second jaw is movable relative to the first jaw between an open position and a closed, locked position. A second handle is movable relative to the first handle and is connected to the second jaw at a fixed pivot. A locking mechanism locks the jaws in the closed, locked position. A movable gripping member can move relative to the jaws when the jaws are in the closed, locked position and a torque is applied to the pliers. | 01-28-2010 |
20100018363 | LOCKING PLIERS - A lockable pliers comprises a fixed assembly comprising a first handle supporting a first jaw. A second jaw is movable relative to the first jaw between an open position and a closed, locked position. A second handle is movable relative to the first handle and is connected to the second jaw at a fixed pivot. A toggle-link locking mechanism locks the second jaw in the closed, locked position. A movable pivot connects the second jaw to the fixed assembly such that the second jaw can move relative to the fixed assembly when the second jaw is in the closed, locked position and a torque is applied to the pliers. | 01-28-2010 |
20100018364 | QUICK ADJUSTING MULTI-POSITION PLIERS - A first member defines an aperture between the jaw and the handle that is defined by a first side wall and a second side wall where the first side wall, second side wall and handle may be integrally formed as a unitary piece. The jaws may also be formed integrally with the handle and side walls. The second member includes an elongated slot and a row of teeth. A pivot member extends along the axis of rotation and includes a tooth engageable with the row of teeth. The pivot member moves between a first position where the teeth are engaged and movement of the first jaw away from the second jaw is prevented and a second position where the teeth are disengaged and movement of the first jaw away from the second jaw is permitted. | 01-28-2010 |

20100218648 | LOCKING PLIERS WITH ONE-HAND ADJUSTMENT - A locking pliers comprises a fixed assembly comprising a first handle and a first jaw. A second jaw is movable relative to the first jaw. A second handle moves relative to the first handle to move the second jaw. A toggle-link locking mechanism locks the second jaw in the closed, locked position. An adjusting screw is provided for adjusting the geometry of the locking mechanism to thereby adjust the jaw spacing and the force exerted by the jaws is provided. The adjusting screw includes a wheel that can be rotated by running the wheel along an object. In another embodiment the adjusting screw includes a sleeve that extends partially over the fixed assembly such that it can be manipulated by the same hand that holds the locking pliers. | 09-02-2010 |
20110203421 | LOCKING PLIERS - A locking tool is provided that comprises an adjustment mechanism that can adjust the distance between the jaws, and the clamping force exerted by the jaws on a workpiece, using the same hand that grips the handles of the tool. A locking tool is also provided where the tool can be locked by moving the handles toward one another. Once locked, the pliers can be unlocked and the jaws opened by squeezing the handles toward one another in the same manner, in the same direction and using the same hand as was done to lock the pliers. As a result the pliers can be locked and unlocked using one-hand and using the same hand movement to both lock and unlock the pliers. | 08-25-2011 |
20110258860 | OPTIMIZED MECHANICAL ADVANTAGE CUTTING TOOL - A cutting tool and method comprises a first lever having a first jaw at one end. A second lever is connected to the first lever at a first pivot where the second lever has a second jaw that is opposed to the first jaw. A third lever is connected to the first lever at a second pivot and connected to the second lever at a third pivot such that relative movement of the third lever relative to the first lever between an open position and a closed position defines a stroke of the tool that corresponds to movement of the hand contact points on the levers toward one another. The third pivot comprises a pin engaging a cam surface where the cam surface has a shape such that the mechanical advantage may increase and decrease through the stroke of the tool and may be variable through the stroke of the jaws. | 10-27-2011 |
20110259149 | METHOD AND APPARATUS FOR A CUTTING TOOL - A method of making a cutting tool comprises providing a lever with a jaw having a cutting edge and a body arranged such that the cutting edge is offset from the body; providing a rotary cutting tool with an edge profile that may be complex and/or non-planar to form a complementary edge profile geometry on the cutting edge by moving the edge profile geometry of the rotary cutting tool along the length of the cutting edge. | 10-27-2011 |
