A vise for securing a chainsaw in a fixed position for field repairs and resharpening the cutting elements on the chain of a chainsaw. The vise is one piece body of generally rectangular shape with two upwardly projecting legs spaced wide enough to accept a chainsaw bar with one leg having a threaded hole and the opposing leg has a raised area. Protruding from the body downward is a tapered tang with serrated/ridges in the tapered side tang, the vise is then pushed into a piece of wood that has a slot cut into it with a chainsaw. the push vise provides a versatile device not limiting the user to just one surface, is safe to carry on your person and is easily and quickly anchored and removed.

A clamp includes a housing, a fixed gripper, a moveable gripper, a driven member, and an actuator. The housing includes first and second tracks. The fixed gripper is coupled to the housing. The driven member is configured to slide within the first and second tracks of the housing. The moveable gripper is operatively coupled to the driven member. The actuator is configured to move the driven member towards a first position to thereby move the moveable gripper towards the fixed gripper. The actuator is further configured to move the driven member towards a second position to thereby move the moveable gripper away from the fixed gripper.

A mobile pipe rack workstation for inspecting and repairing pipe materials, a “Pipe Station.” By folding the pipe station's load/unload arms, removing any tool's from the tool mount and lowering the gantry by retracting the risers; the pipe station is transportable on public roadways without permitting, escorting, or special signage required for oversized loads.

A wire clamp includes a base and first and second jaws. The first jaw is pivotally mounted to a first upright portion of the base via a first pivot axle, and the second jaw is pivotally mounted to a second upright portion of the base via a second pivot axle. The first and second jaws crisscross each other at an overlap area, and are spring-biased to pivot relative to the base towards a closed position. Respective hook members of the first and second jaws define a mouth above the overlap area that is configured to receive a wire. A size of the mouth adjusts automatically to a size of the wire within the mouth as the first and second jaws pivot towards the closed position. The wire may be held within the mouth in an in-line orientation with a corresponding terminal to which the wire will be crimped.

A twin clamp, comprising two receptacles (61, 62), each of which has two movable clamping jaws (611, 612, 621, 622) and by means of each of which an elongate profile segment (71, 72) having a circular cross-section can be clamped in the contact section, each elongate profile segment having a centre axis (D71, D72) and an outside diameter, wherein two clamping jaws (611, 612, 621, 622) of different receptacles (61, 62) are coupled to one another via a respective differential gearing (41, 42) and two clamping jaws (611, 612, 621, 622) of the same receptacle (61, 62) are coupled to one another via a synchronous gearing (51, 52) and the position of the centre axes (D71, D72) of the clamped elongate profile segments (71, 72) is independent of the size of the outside diameters of the elongate profile segments (71, 72).

An embossing device that serves for preparation of a combined form-fit and friction-fit clamping of a workpiece in a respective clamping chuck. The embossing device includes jaws having embossing teeth that are formed on insertion bodies. The insertion bodies include a penetration edge respectively with which they penetrate into the workpiece surface in order to create a depression with defined dimensions. For this a workpiece contact surface is formed on the insertion body, preferably in the proximity to the bar-like projection that stops the penetration process of the bar-like projection as soon as the workpiece contact surface gets in contact with the workpiece surface during the execution of the embossing process. Then the force required for movement of the jaw increases considerably from which a control device generates a switch-off signal for the operation device.

The invention relates to vise pivotal jaws for holding irregular shaped objects and that are modular to work on various sized prior art vises. Also relates to pivotal jaws having aid to return back to a neutral center position. The design allows ease of disassembly for cleaning and reassembly.
