Abstract: A tool is comprised of a combination of a vice grip brand adjustable clamping pliers and a parallel jaw adjustable wrench such that the parallel jaws have been mounted on the end of the adjustable clamping pliers and the handle of the parallel jaw adjustable wrench has been discarded and the jaws of the clamping pliers has been discarded resulting in a new and novel tool with some capabilities of both tools and in addition many new uses.
Abstract: The invention relates to a wiring tool for wiring electric, multipin plug connectors, connector strips or the like, using clamping cutter techniques, comprising a support for the binder receiving the lines to be connected and an opposed support for the binder, the support being adapted to be displaced with respect to the opposed support parallel to itself and towards the opposed support, the support being supported in its mounting, in accordance with the invention, on at least one wedge adapted to be linearly displaced by means of a pushrod.
Abstract: The pliers include a frame having a hand grip portion and two, spaced, laterally projecting leg sections. At least one of the leg sections is fixed to the hand grip portion of the frame and has formed thereon a stationary jaw, which confronts a movable jaw that is carried by a support member that is mounted on the frame to extend transversely between its leg sections, and for reciprocation generally parallel to its hand grip portion. The support member is connected to a handle, which is pivotally mounted on the frame to reciprocate the movable member and its jaw in opposite directions, thereby to shift the movable jaw toward and away from the stationary jaw. The movable jaw is mounted on its support member for adjustment thereon into any one of a number of different positions, thereby to adjust the span between the jaws.
Abstract: A diminishing arm toggle linkage has the work site within the toggle geometry and thereby provides exponential force enhancement. In preferred embodiments the mode of operation shifts on demand from a light-load-pivoting mode to a heavy-load-rolling element mode thereby easing operation and reducing friction and wear so as to provide prolonged durability and continuing dimensional accuracy. When the toggle linkage is embodied in a crimping tool an optional anti-reversing ratchet assembly prevents the tool from opening during use until a crimp is completed.
Abstract: A wrench is formed of two jaws which are shaped to conform to standard fasteners, such as hex nuts, and are supported within a housing for translation relative to each other for gripping the fastener. Closing force on the jaws is exerted by a pivoting handle acting through an overcenter linkage. A crank-shaped lever is positioned contiguous to the overcenter linkage permits operation of the wrench with the jaws being either tightly clenched or slightly withdrawn from the fastener. One end of the overcenter linkage is connected to the housing by a screw which is rotated to set a spacing between the jaws.
Abstract: A wrench includes two mutually movable jaws that are mounted by means of parallel linkages to a housing forming the handle. A rod is axially movable in the handle by means of an internally threaded sleeve extending into the bottom of the handle. The rod is connected at its top, by a pivotal link, to the top of the outer member of the parallel linkage. A locking member is pivotally attached to the housing and there is pivotally connected thereto, a wedge-shaped member that is adapted to engage a locking sleeve loosely mounted on the rod. The rotation of the threaded sleeve adjusts the distance between the jaws, while the engagement of the stop member with the locking sleeve prevents the movement of the jaws when they are in a working position.
Abstract: Crimping tongs in particular for crimping a sleeve on a cable, said tongs having jaws coupled to each other so that one moves relatively to the other, a cam (15) driven by a ratchet wheel (16) which actuates a toggle joint device (20,21,22) a catch being installed on the moving handle (13) so as to drive the ratchet wheel step by step by moving the moving handle, the toggle joint device making the moving jaw (12) rotate in the closing direction. With a view to axial crimping, the moving jaw (12) has a moving die (14) which moves rectilinearly. A spring (25) biases the toggle joint to move the one jaw toward the other, and a trigger (19) is pressed to open the jaws sufficiently for insertion of a sleeve to be crimped. Releasing the trigger causes the jaws to hold the sleeve under the action of spring (25); so that the crimping action can be performed with one hand.
Abstract: A portable manually operated tool for applying multicontact connectors to flexible flat cable includes a pair of pivoted jaws which include respective connector body and cover holding members. The jaws are opened and closed by manually actuated handles including a locking toggle mechanism. The connector holding members include cooperating alignment guides and position stops. One of the connector holding members is mounted for limited movement on one of the jaws to provide for engagement of the alignment guides and to provide even distribution of the clamping force on the connector. The tool also includes a retractable cable cutter and positioning stop as well as a cable alignment and support tray.
Abstract: In a locking wrench designed to grip an object between a stationary and a movable jaw firmly under the action of a toggle link associated at one end with the movable jaw and at the other end with a threaded bolt, the movable jaw is divided into two separate parts, that is, a body member pivotally secured to the stationary jaw and a grip member supported on the body member for sliding movement relative thereto so that the distance between the grip faces of the grip member and the stationary jaw may be adjusted as desired. With this structure, an optimum force of grip is readily obtainable at all times for thickness of the object to be gripped without the need of adjusting the threaded bolt therefor.

The first and second jaws are connected to the first and second levers by a mechanism for maintaining the jaws always parallel. It further comprises a rapidly actuated device for opening the jaws when the first and second levers are moved toward each other.
Abstract: A hand tool for assembling two or more articles along an extended plane. Arcuate motion of a movable handle is converted to axial movement of a presser plate to assemble the articles placed on an aligned platen. The movable handle controls a drive bar which is coupled to the tool frame by pivotally movable links which move the drive bar in two orthogonal directions and to the presser plate to move it in two orthogonal directions by means of pivotally movable links coupled to the drive bar. The movements along one orthogonal axis cancel one another and the movements along the other orthogonal axis are cumulative whereby the presser plate is moved only in the direction of the platen.
Abstract: Plier-type hand tool comprises a frame having spaced-apart jaws and a fixed handle extending therefrom. One of the fixed jaws has a ram therein which is reciprocable towards and away from the other jaw. The actuating means for moving the ram comprises a movable handle which is pivoted to the frame. Closing of the handles causes two toggle mechanisms to be straightened which are concatenated with the ram. The arrangement of the toggle mechanisms is such that a relatively deep throat is provided between the jaws for the acceptance of a wide workpiece such as a flat electrical cable. A removable tension member may be provided on the ends of the jaws to prevent excessive flexure of the jaws during use of the tool.
