Abstract: A strap wrench includes a strap that is a continuous loop and has notches. No portion of the strap is affixed to any portion of the wrench. The strap is placed around an object that needs to be turned such as an oil filter on an engine. A tension mechanism is then used to tighten the strap into place around the object to be turned. A ratchet mechanism engages one or more notches on the strap to prevent movement of the strap in one direction while allowing movement of the strap in the opposite direction. The combination of the notched continuous loop strap and ratchet mechanism allow the strap wrench to have a ratcheting action after the strap is tightened into place around the object to be turned.

Abstract: A fiber optic cable trough notching system with a punch and a punch aperture spaced apart by a wall receiving opening for receiving a fiber optic cable trough component wall, the punch disposed to impart a force on the trough component wall to deform it into the punch aperture, and thereby create a detent and/or projection. The detent and/or projection are then utilized to operatively attach two trough components.

Abstract: The invention is an adjustable plier wrench hand tool, combining the useful functions of standard adjustable wrenches with standard vise grip pliers. The invention has a main body, a plier handle having a plier handle head, and an upper and lower jaw. The lower jaw is slidably mounted to the main body and capable of moving towards and away from the upper jaw. A thumbscrew is threaded and mated to corresponding teeth on a rack integrally formed with the lower jaw, such that by rotating the thumbscrew, the lower jaw moves towards and away from the upper jaw. The thumbscrew has a bore through which a stub shaft, extends from which a cam, protrudes. By bringing the plier handle into a closed position, an apex of the plier handle head pushes against a cam surface of the cam, forcing the cam, the thumbscrew, and hence the lower jaw upwards, in effect causing a compression between the lower jaw and the upper jaw, so as to firmly grip an object typically a nut.

Abstract: A parallel jaw pliers apparatus is comprised of a first lever member having a handle at one end and a first jaw surface at its opposite end, a second lever member pivotally connected to the first lever member and having a handle at one end and a pair of arms at its opposite end, and a jaw member mounted to the first lever member for translatory movement relative thereto and mounted to the second lever member for pivoting movement relative thereto. The connections between the first and second lever members and the jaw member provide an unobstructed working area between opposed jaw surfaces of the pliers apparatus. The component parts of the pliers apparatus are constructed to center force distributions through the center of each of the component parts when the pliers are in use.

Abstract: A self-adjusting tool having first and second elongated members, each of which have a workend and an oppositely located handle means for applying force to the tool. The first member includes a raceway positioned intermediate of the work end and handle. A connector is provided adjacent to the work ends for slideably and pivotally connecting the first and second members together. The connector includes an elongated slot in the first member having ratchet teeth along at least a portion of one edge thereof and a pawl positioned to slide within the slot and to pivotally engage the ratchet teeth. A fastener for securing the first and second members slideably together and securing the pawl in the slot is provided as part of the connector. A torsion arm with first and second ends is operably positioned between the first and second members. The first end includes a torsion element connected to the second member and the second end is slideably positioned within the raceway.

Abstract: Disclosed herein is a patellar clamp which includes a fixed jaw having a spike centrally disposed on a part spherical surface with this spike being axially aligned with a reciprocating plunger. The plunger is operated by a second handle pivotably disposed with respect to the first handle and spring biasing means between the handles biases them in a direction of separation of the plunger and spike. The inventive patellar clamp is utilized to install a patellar button onto a resected patella.

Abstract: The invention relates to a tool for crimping, cutting, pressing or the like having a linear work path and a lever drive engaged between the gripping levers and the tool head, with two cover plates (1), each of which form an integrally enclosed frame and which are firmly connected to one another by an intermediately located, upper profile plate (2), and a lower profile plate (3) which can be moved up and down by the lever drive and is guided between the two cover plates (1) by a guide plate (16) being superimposed on the profile plate (3), which guide plate (16) extends into the frame (1), with the upper and lower profile plates (1,2), on the sides facing one another, forming or supporting tools which effect the crimping, cutting, pressing or the like.

Abstract: A hand-operated tool of the pliers type includes a body member in which a rectilinear guiding track for a jaw carrier is provided. One stationary jaw for treating a working piece is arranged at one end of the guiding track and another jaw on the jaw carrier. A handle is pivoted to the body member laterally of the guiding track and is provided with faces for engagement with co-operating faces on the jaw carrier so as to press the jaw carrier and the jaw mounted on it towards the stationary jaw when the handle is activated.

Abstract: In a pliers-type tool having a stationary first handle and a second handle pivotally movable relative to the first handle, a slidable jaw carrier is movable along a rectilinear guiding track in a body member due to the pivotal movement of the second handle. The first handle is fixed to the body member. The second handle is in engagement with a toggle mechanism including a driver arm which, in turn, is pivotally attached at a stationary location to the body member. When the second handle is pivoted, the driver arm contacts, in a gliding manner, the jaw carrier and moves it rectilinearly in the guiding track. The driver arm extends transversely of the rectilinear guiding direction of the guiding track. Forces acting through the driver arm in the direction transversely of the rectilinear direction of the guiding track are prevented from affecting the movement of the jaw carrier. The second handle can be connected to the first handle by a connecting link.
