Abstract: A lockable pipe support holding device of the plier type is provided, having large flat jaws for gripping pipe straps, shoes, hangers and materials. The jaws have a textured inner surface and notched grooves along the lateral edges to promote firm grip on metal and bending of the same. A āUā shaped recess along the front edge of the jaws allows fasteners to be inserted into a strap or similar object being securely held by the tool. A user may adjust the gap between jaws by means of an adjustment screw in a handle. In addition the jaws may be locked in place and then unlocked by means of a lever housed in a handle. Consequently, a user may insert fasteners into a working area of an object without having to hold onto the tool while doing so.
Abstract: A tool for removing hose from objects includes a handle having a first jaw fixed to the handle and a second jaw which is movably connected to the first jaw in a scissors-like way. The first and second jaws have two respective clamp portions so as to clamp the hose. An adjustment unit includes a first member pivotably connected to the first jaw and a second member pivotably connected to the second jaw. A bolt threadedly extends through the first and second members such that when rotating the bolt, the two clamp portions are moved toward each other. An operation unit includes a cable and a bar connected to the cable. The tool is pulled along the object on which the hose is connected by pulling the cable.

Abstract: The present invention is directed to an improved hand tool for using one hand to grasp a workpiece between a first and a second jaw of the hand tool and adjust the force applied to the workpiece. The hand tool includes a first arm and a second arm, the second arm operably linked to the first arm so as to cause relative motion of the first and second jaws upon motion of the arms. The hand tool further includes a control arm having a first end pivotably linked to the first arm and a second end pivotably linked to the second arm at a moveable pivot location. Movement of a force adjustor located on the second arm in a first direction moves the moveable pivot location so as to increase the level of force required on the second arm to move the control arm into an overcenter lock position.
Abstract: A plier-like tool having links added between the jaws and the body of the pliers. The links not only extend the length of the jaw side of the pliers, but also pivot relative to each other and perpendicular to the opening and closing direction of the pliers. The screws in these links can be left untightened to permit the links to pivot allowing the jaws to gain access into restricted areas otherwise inaccessible. Even with the link-screws loose the gripping force is transferred through the links to the jaws enabling the user to still grip objects or even retrieve them by simply pulling the pliers back out and letting the links follow. An additional aspect to the flex-link pliers is that the link-screws can be tightened so the links maintain their position relative to each other so the user can create any shape pliers desired.
Abstract: An adjustable jaw pliers wherein the adjustable jaw pliers have a quick release threaded rod positioning portion which engages the threaded rod which has a pliers jaw attached to one end of the threaded rod. The pliers jaw which is attached to the threaded rod can be positioned at any distance from the other pliers jaw of the pliers by disengaging the threaded rod laterally from the quick release threaded rod positioning portion of the pliers. The pliers handle containing the quick release threaded rod positioning portion has a locking device attached to the pivot pin of the pliers. The locking device locks the threaded rod into the quick release threaded rod positioning portion of the pliers. Another aspect of the adjustable jaw pliers has the threaded rod attached to one of the pliers handle portions and a quick release adjustable position pliers jaw is positioned laterally to the threaded rod to and locked into place by a locking device.
Abstract: The chip cracking device is for engaging the lateral surfaces of a mounted computer chip. The device body has a pair of curved leg members having upper and lower portions with inwardly extending centrally disposed structures. A pivot member is operative on the inwardly disposed structures and an adjustable and hand operable knob is operative on the upper portions of the leg members. The chip cracking device further has opposing jaw members with lateral cutting edges of a predetermined slope so that the adjustable movement of the knob causes the cutting edges to crack and separate the chip body for subsequent removal from its mounting structure.

Abstract: A pair of pliers is equipped with an expander unit that spreads the handles so that the jaws will forcibly grip objects from the inside. External teeth on the jaws aid in gripping.
Abstract: An electrode holder to be connected to a welding current cable and having a pair of jaw support members pivoted to a tubular member therebetween which has a bore receiving said cable, the cable being connected by separate conductors to electrode gripping jaw pieces in said support members, and a pair of springs separately urging the respective jaw support members about said pivot to bring the jaw pieces together and clamp an electrode therebetween, the ends of the springs being supported in a collar which surrounds the tubular member and is adjustable longitudinally thereof to adjust the spring pressure closing said jaw pieces.
