Abstract: Wrenches commonly known as “pipe wrenches” which include sidewall surface configurations within a channel extending through a housing component of the wrench are described. Also described are wrenches that include one or more shim components that can be positioned in the housing channel. In addition, methods for reducing failure or fracturing of the wrench due to application of high side or lateral loads are described.

Abstract: Tools having provisions associated with a wrench and a vise are described. The tools can include lateral support members extending from the handle that increase stability during use as a vise. The support members can be removed and/or placed in a non-use position when the tool is used as a wrench. The tool can also include support plates that provide a clearance space between a workpiece and a movable jaw of the tool. Various other features of the tools are described.

Abstract: An automatically-configurable screwdriver assembly includes a shaft with a hollow interior portion, a proximal end, and a distal end. A first blade is fixedly coupled to the distal end of the shaft to prevent motion in a proximal direction and a plunger is at least partially located within the hollow interior portion of the shaft and slidable therein between an extended position and a retracted position. A compression member exerts force on the plunger in a distal direction and a second blade is mechanically coupled to the plunger so that, when the plunger is in the extended position, the first blade and second blade extend approximately equidistant from the distal end of the shaft and form a substantially perpendicular configuration with one another and when the plunger is in the retracted position, the first blade extends a greater distance from the distal end of the shaft than does the second blade.

Abstract: Disclosed is a spanner which is generally used as a typical tool for tightening or releasing a bolt. The spanner is capable of tightening or releasing a bolt continually in one direction by the effect of a toggle bar (400) pivotally mounted on a jaw of two jaws (200, 300) of the spanner head in a state that the toggle bar is urged to pivot toward one direction. A protrusion (30, 32) is formed on a distal end of the other jaw of the spanner head for gripping an angular portion of the bolt head so that it is possible to prevent the spanner head being readily disengaged from the bold head.

Abstract: A self-locking wrench includes a movable jaw which can be moved by a manual actuator. Motion of the actuator is transmitted to the movable jaw by a leaf spring. When moving the movable jaw toward an open position, the leaf spring becomes deformed and stores energy so as to be able to subsequently drive the movable jaw toward a closed position when the actuator is released.

Abstract: A vise comprising a main bar; a guide holder pivotably mounted on the main bar and having a guide channel; a slide bar coextensive with the main bar and extending through the guide channel, and a holding pin secured to the guide holder and urged into engagement with the inner side face of the slide bar by a spring. A pair of jaws opposed to each other extend from the front ends of the bars respectively at right angles to the bars. When the guide holder is depressed against the action of the spring, the holding pin is disengaged from the inner side face of the slide bar, rendering the slide bar freely slidable forward or rearward.

Abstract: A pipe wrench which is locked in adjustment by engagement of rack-like teeth on the stem portion of the movable jaw with similar teeth on a slidable member carried in a wide groove in a rocking sleeve. The wrench is adjustable with one hand by squeezing the sleeve and slider to disengage the teeth, then moving the jaw stem via a spur engageable with the finger. The major parts of the sleeve and slider may be made of welded steel stampings.
