Abstract: An improved parallel-jaws locking wrench/plier with toggle action includes a body element, a fixed jaw, and a moving jaw capable of moving rectilinearly by means of an action cam, which is pivotally connected to a locking lever coupling respectively to the upper ends of a fulcrum bar and a releasing lever thereof. A handle secured to the body element has an axially adjustable element to regulate the opening of the jaws. Close to the pivot of the releasing lever are two outstanding members disposed respectively opposite sides thereof. Gripping the locking lever towards the handle till being stopped by the two outstanding members hitting said handle will toggle continuous gripping/clamping action on a workpiece. Gripping the releasing lever towards the handle will render the two outstanding members to serve as fulcrums, providing the former with leverage to force the toggle linkage back to its relaxing condition to release the workpiece. The releasing action requires only one hand.

It is possible to preset a rest position of the second plier unit (Z2) relative to the first plier unit (Z1 ) in the operating direction (A).

Abstract: A crimping tool capable of forming a uniform series of deformations or crimps on a workpiece, such that at least a portion of the workpiece can be modified to acquire an arcuate shape with a predetermined radius. The crimping tool includes a pair of arms and an associated pair of jaws. The tool further includes an adjustment feature associated with one of the arms for adjusting and gaging the distance between the jaws when in a crimping position. As such, the degree of deformation or crimping that can be applied by the jaws is positively limited by the adjustment feature, which physically establishes the minimum gap width between the jaws during a crimping operation. The jaws include die members specially configured to promote accurately placed and uniform crimps in a workpiece.

Abstract: A bottle cap remover used to separate a cap from a bottle wherein the cap has an upper section and a lower section, and at least a portion of the upper section of the cap protrudes radially outwardly beyond the lower section of the cap.

Abstract: A mechanism for removing a cork from a champagne bottle, wherein a manual force is applied along the bottle axis, so as to avoid side thrust forces that might cause the bottle to slip out of the person's hand. A lazy tong linkage is utilized to apply a magnified force onto the undersurface of the cork, whereby the person is able to exert a smooth controlled manual force on the mechanism, as opposed to a massive abrupt force that might tend to cause the bottle to drop or tip over.

Abstract: A wrench of the type having one handle member connected to a pivotal arm member at a pivot point. The handle member, and the pivot arm member terminate in a jaw member, the jaw in the handle member being fixed. Advancing a screw member causes the pivot arm member to rotate about the pivot point so that the jaw members are brought together. A pair of slots translate the rotating motion of the pivot arm member about the pivot point into linear components. The jaw member at the end of the handle member and the pivot arm member are biased apart from one another by a spring, but the bias may be overcome by squeezing the handle and pivot arm member or by advancing the screw member. When the screw member is fully retracted, the spring separates the jaw members. When the screw member is advanced, it prevents separation of the jaw members.

Abstract: A bottle cap opener in the form of a fixed base includes a laterally directed U-shaped bottle neck embracing hollow portion for receiving a portion of the neck of the bottle below a rim. A lever is pivotally mounted to and overlies the base. The lever includes a front arm having an end abutting the U-shaped hollow portion of the base and engagable with the lower edge of the bottle cap to the side of the opener proximate to the handle. A spring mounted to the base engages the lever to bias the front arm downwardly and toward the U-shaped hollow portion. A magnetic appendix is hinged to the U-shaped hollow portion to the side thereof diametrically opposite the pivoted handle and extends in line with the handle for movement between a first position overlying and in contact with the top of the bottle cap in an upwardly oblique raised position with respect thereto, permitting manual removal of the cap from the appendix after the cap is separated from the bottle rim.

Abstract: A wrench of the type having two handle members pivotally connected to one another at a pivot point. Each handle member terminates in a jaw member. Advancing a screw member causes one of the handle members to rotate about the pivot point so that the jaw members are brought together. A pair of slots translate the rotating motion of the handle member about the pivot point into linear components. The jaw members at the end of each handle are biased apart from one another by a spring, but the bias may be overcome by squeezing the handle or by advancing the screw member. When the screw member is fully retracted, the spring separates the jaw members. When the spring member is advanced, it prevents separation of the jaw members.

The grip has an inwardly disposed circular flange, a side-facing cutout and an axial extension which passes through the closed housing end. The side-facing cutouts are sized to allow the enlarged head of a stopper to be inserted laterally into the grip. A crescent shaped cam is pivotally mounted to the extension and bears against the outer surface of the closed end. A handle is used to pivot the cam which pulls the grip axially upwardly. A spring, between the grip and the housing, biases the grip axially toward the open housing end. The extractor is mounted over the stopper with the open end against the container and the grip lip under the lower edge of the cork head. Rocking the handle pivots the cam to raise the grip.
