Abstract: The main fixed handle optionally incorporates two swivel out arms, which can form part of a three-legged base. When operated thus, the jaws and moving handle point generally upwards from the formed base, the moving handle can now be operated by one hand leaving the other free to position the workpiece. The moving handle can incorporate a further locking switch that can be utilised in both a switchable locking position or non-locking position upon a sprung toothed strut between the handles, at least one of which further incorporates a curved resilient portion in order to provide useful sprung closure of the parallel moving jaws upon the workpiece in the locking method. A lanyard can be optimally attached to the swivel out arm ends to provide the user with a chest mounted portable vice.

Abstract: Pliers with adjustable jaw span have a first member (1) and a second member (2) which cooperate with each other. A long slot (13) is formed in the first member (1). The second member (2) is connected with the first member (1) by means of a pivot (3) passing through the long slot (13), and rotatable around the pivot (3) relative to the first member (1), while adjusting the span of the jaws by varying the position of the pivot (3) within the long slot (13). The edge of the long slot (13) is provided with ratchet teeth (14). The pivot (3) is engaged with the ratchet teeth (14) by a pawl (31), thus the pivot is movable within the long slot (13) in a first direction and immovable in a second direction which is opposite to the first direction. The pliers are convenient to operate because when the position of the pivot (3) is moved within the long slot (13), the user's operation is required only for the movement in one direction.

Abstract: Pliers, with two arms that are joined together via an articulation pin. One of the arms has a protuberance with a lateral channel that extends via one of the orifices, a pusher being located in the channel and having an inner channel that accommodates a spring that acts between the pusher and the arm. The articulation pin is joined by means of screwing to the pusher in the region of the lateral channel, a toothed claw being arranged coaxially therebetween with mechanical continuity. The pusher is continued as an extension located on the walls of the other orifice in the work position. Applicable to hand tools.

Abstract: A first member defines an aperture between the jaw and the handle that is defined by a first side wall and a second side wall where the first side wall, second side wall and handle may be integrally formed as a unitary piece. The jaws may also be formed integrally with the handle and side walls. The second member includes an elongated slot and a row of teeth. A pivot member extends along the axis of rotation and includes a tooth engageable with the row of teeth. The pivot member moves between a first position where the teeth are engaged and movement of the first jaw away from the second jaw is prevented and a second position where the teeth are disengaged and movement of the first jaw away from the second jaw is permitted.

Abstract: A method and device is disclosed for clamping an object with quick adjusting pliers. A top jaw has a bottom handle, a slot, and a series of ridges located around the slot. A pin extends through the slot and includes an engagement element. A bottom jaw has a top handle and another opening for receiving the pin. The engagement element engages at least one of the series of ridges in a first position, wherein the top jaw and bottom jaw pivot about a first axis that extends through a longitudinal axis of the pin, and wherein the engagement element is moveable along the first axis from the first position to a second position wherein the engagement element does not engage any of the series of ridges.

Abstract: A method and device is disclosed for clamping an object with quick adjusting pliers. A top jaw has a bottom handle, a slot, and a series of ridges located around the slot. A pin extends through the slot. A tongue element has a first opening for receiving the pin. A bottom jaw has a top handle and another opening for receiving the pin, wherein the tongue element engages one of the series of ridges, and wherein the top jaw and bottom jaw pivot about a first axis that extends though a longitudinal axis of the pin, and wherein the tongue element is moveable relative to the ridges to allow for engagement or disengagement with said ridges.

Abstract: A clip is constructed to include two pivoted clip elements, a torsional spring provided between the clip elements and adapted to hold the clip elements in the open position, a toothed rod member and a pres control structure provided inside the clip elements and adapted to lock the clip elements in the close position to hold down the workpiece.

Abstract: In a heat sealing operation for environmentally isolating joints and connections, a spring actuated clamp is utilized to provide positive engagement of the heat shrinkable material in the area between the members being connected. The clamp has two juxtaposed clamp arms with opposed convex clamping jaws. The clamp arms are resiliently loaded by a coil spring so the convex surfaces on the clamping jaws are placed into a clamping relationship on the heat shrinkable material.

Abstract: Utility pliers for single-handed manipulation, capable of automatically adjusting the distance between gripping jaws in relation to the size of the workpiece to be gripped, and utilizing one or more hidden springs to cause the automatic adjustment function. Alternative embodiments enable reduction of manufacturing costs, improved location of certain operative components, and the selective inclusion of additional features which enhance the use and operation.

Abstract: A multi-functional adjustable hand tool useful in attaching shoes to the hooves of horses is comprised of two lever members pivotably interengaged in the general manner of pliers and having opposed fixed and adjustable jaws. The adjustable jaw is capable of being disposed in several positions relative to the fixed jaw to provide the various jaw separations of clinching tools used by farriers. A nail cutter associated with the jaws provides even further versatility of the tool, causing it to be a replacement for several standard farrier's tools.
