Abstract: An increased torque applying pliers which utilizes two separate sets of jaws with each set of jaws having their own pivot axis. Each set of jaws are reversely oriented relative to each other. The sets of jaws are pivotally connected together with this pivot connection also being connected to a handle assembly. The handle assembly comprises two handles which are also pivotally connected together with the pivot axis for the handle being confined within a central cavity that is formed by the jaw members. The utilizing of a separate pivot axis for the handle members which is spaced from the connecting axes that interconnect the jaw members and the handles provides for the application of an increased amount of torque when clamping of the pliers onto an exterior structure.

Abstract: A versatile use pliers which has a first pair of jaws reversely positioned relative to a second pair of jaws. Both pairs of jaws are to be simultaneously movable between an open and a closed position. Movement of the jaws between the open and closed position is accomplished by a handle assembly upon which both sets of jaws are mounted. The handles are pivotable about one-hundred and forty degrees which will remove one set of jaws from an operating position and substitute the other set of jaws in the operating position. The pair of jaws are connected together about a connecting axis arrangement which is separate from and spaced from the pivot axis arrangement for each pair of jaws.

Abstract: The invention presents a soundboard for acoustic musical instruments. Its use is possible for all acoustic musical instruments in which the sound radiation takes place by means of soundboards or resonant bodies composed of soundboards (or resonant back plates), preferably for bowed stringed instruments. The soundboard according to the invention is produced as a composite fiber sandwich. The core plate of the sandwich construction is provided with at least one recess. The soundboard according to the invention makes possible an increased sound radiation by comparison with the conventional soundboards made from solid wood or composite.

Abstract: This invention relates to an ancillary for a spinal osteosynthesis system comprising at least one implant that will be implanted in a spine. The implant comprises accommodation means located approximately along a centerline and that will accommodate at least one rod type connecting element. The ancillary comprises holding means that will cooperate with the said implant, and a manipulation means free to move with respect to the said holding means that will be used to manipulate the said connecting element. The said holding means will be arranged on one side of the accommodation means, and the said manipulation means comprises attachment means that will cooperate with the said implant on the side of the centerline of the accommodation means opposite the accommodation means. This invention also relates to a process for implantation of a spinal osteosynthesis system comprising at least one implant, using an ancillary.

Abstract: A Tool structure including a tool assembly and two grips. The tool assembly is formed by a first, a second, a third and a fourth arms which are pivotally connected with each other to form a mechanism as a four-link mechanism. The first and second arms and the third and fourth arms respectively form two kinds of tools. Two ends of the grips are respectively pivotally connected with the pivot sections of the first and third connecting sections and the pivot sections of the second and fourth connecting sections. Therefore, when the grips are held and closed to make the tools formed by the first and second arms and the third and fourth arms get close to each other and close, the two grips are not coaxially pivotally rotatable with the first and second arms and the third and fourth arms. Accordingly, the maximum opening extent of the two grips can be reduced for easy holding.

Abstract: The present invention is a multi-purpose device for use by fishermen. A first lever arm includes a handle, a primary jaw element and a secondary jaw element. A second lever arm includes a handle and a primary jaw element. The second lever arm is pivotally connected to the first lever arm so that the primary jaw elements form a pair of primary jaws for gripping, crimping or cutting. A jaw member includes a flange and a secondary jaw element. The jaw member is pivotally connected to the first lever arm in proximity to the secondary jaw element so that the secondary jaw elements form a pair of secondary jaws for gripping hooks embedded in the gullet of a fish. A connecting link is pivotally connected between the second lever arm and the jaw member, so that the primary and secondary jaws simultaneously open and close in response to pivotal movement of the handles relative to each other.

Abstract: A multi use tool having a pair of links pivoted to one another by a pivot intermediate the ends, cooperating inwardly facing jaws adjacent one end of the links, the jaws operable toward one another to grip an object, separation jaws adjacent the opposite end of the links, a handle formation defined on each link between the jaws and the pivot and a spring for biasing the jaws apart and the separation jaws together, whereby squeezing the handle formation will move the jaw toward one another and the separation jaws away from one another.

Abstract: An expansion tool for spreading the side walls of a partitioning track comprises first and second members each having a handle portion and a jaw portion. These members are coupled together so as to cause the jaw portions to compress when the handles are compressed. Coupled to each jaw portion is a spreading member each of which includes a contact or spreading surface. As the jaws are compressed, the contact surfaces move apart.

Abstract: A chain link tool including a pair of jaws on one side of the tool adapted to close the respective eyes of a cross chain connecting link, said jaws moving together as the handles are moved together and conversely, and such that a groove and a projection on the other side of the tool are adapted to receive the transverse portion of the side chain and to grasp the curved end of the cross-chain connecting link respectively when the handles are apart and to disengage the cross-chain connecting link as the handles are moved together.

Abstract: A lineman's pliers which is designed to push or pull a snake through a conduit or tubing with less effort and time due to the provision of special gripping and alignment means that do not crimp the snake and apply more effective gripping action. The pliers include a pair of crossed levers provided with a head at one end having front and rear pairs of opposing jaws and opposing elongated handles at the other end whereby said jaws may be operated to effectively grip a snake.

Abstract: A pair of pliers are provided for fastening a split annular hose clamp whose opposite ends are provided with ratchet teeth adapted for interlocking engagement. The pair of pliers has a pair of primary jaw members used in fastening the hose clamp and a pair of secondary jaw members used for removing the hose clamp by applying force in opposed lateral directions to the interlocked members. The primary jaw members and the secondary jaw members are located on the same side of the pivot stud remote from the plier's handles.

Abstract: A pull tab attachment tool comprises a pair of first and second levers connected together for pivotal movement and having respectively first and second handle portions and opposed jaw portions extending from their one ends. The second lever has a roller. A third lever is pivotally connected to the first lever. An urging means acts between the first and third levers to normally urge them apart so that the third lever is held in rolling engagement with the roller. When the first and second handle portions are manually actuated to move toward each other, the opposed jaw portions are brought into engagement with each other to provide a first pressing structure, and one end of the third lever is brought into engagement with the one end of the first lever through the rolling action of the roller along the third lever to provide a second pressing structure.
