Abstract: A pair of pliers for gripping, twisting, and cutting wires having undulating wire gripping surfaces, a wire cutting cavity, and a resilient wire gripping material. The undulating wire gripping surfaces have high and low portions that unequally traverse the gripping surfaces and extend unequally beyond the centerline of the pliers. Such a configuration provides an equally distributed gripping force for an entire range of wires without causing any nicks and scrapes on the wire. The cutting cavity has a plurality of surfaces that form tiger tooth-like members. The geometry formed by the cavity's surfaces and tooth-like members provides a large surface area for the resilient gripping material to adhere to.

Abstract: A reversible wire twisting plier tool is provided, which includes a pair of plier arms each having a jaw portion and a handle portion and which are pivotally interconnected and movable between an open position and a closed position. A plier rotating mechanism is mounted on one of the handles. The rotating mechanism includes a tubular member and a double spiral shank having a left hand groove and a right hand groove, axially slidably mounted within the tubular member. First and second gears are disposed within the tubular member, one gear being slidably engaged in one of said grooves and the other being slidably engaged in the other groove. A gear actuator is provided which is movable between a first actuated position wherein the actuator engages the first gear and a second actuated position wherein the actuator engages the second gear to selectively impart a clockwise or counterclockwise motion to the shaft depending upon which gear means is engaged.

Abstract: An electrically heated thermal wire stripping hand tool device is provided which uses electrically heated ceramic blades or jaws having severing edges to remove insulation from electrical wire. The tool includes a pair of arms hingedly connected which removably mount stripping jaws thereon at their distal ends. Each jaw has an insulation severing edge which when heated will melt or otherwise degrade the insulation on the wire when it coacts with the severing edge on the mating jaw. Electrically heated wires and circuitry are provided which heat the severing edges of the jaw. Contacts are provided which removably secure each jaw to one of the arms to provide electrical power thereto. The jaws and contacts are also provided with alignment devices which coact with each other when the jaws are mounted on the arms to provide alignment in both the x and y axes of the plane on which the jaws mate for severing insulation.

Abstract: A dispensing device includes a frame designed to receive and support a cartridge containing a viscous product.

Abstract: A fluid actuated dispensing device having a valve assembly and an actuating piston provides incremental movement of a drive piston within a tube holder. The valve assembly includes a trigger piston and a valve ball biased into engagement with a valve seat. A trigger is adapted to engage the trigger piston and urge the valve ball away from its seat to allow fluid to enter an actuating chamber. The increase in fluid pressure within the chamber drives an actuating piston from an initial position to an extended position in the chamber. The actuating piston is adapted to drive a washer off-center against a push rod during the stroke of the actuating piston. The washer cocks and grabs the push rod and urges the rod forwardly within the tube holder. A drive piston connected to the push rod is thereby driven forward within the tube holder for the full stroke of the actuating piston.

The lever sections are pivotally interconnected together along the boss portions for manipulation between internal and external tool operating positions. Movement between the internal and external positions is provided by a rotatable eccentric knob. The knob carries a spring biased lock for securing the levers in a selected one of its operating positions.

Abstract: A tool for removing a split washer, such as a brake lever "C" clamp, from a groove in a projection, such as would be found on a brake lever pivot is provided. The tool includes a first lever member; a second lever member pivotally interconnected to the first lever member at a pivotal axis; a gripping component manipulatable by the first lever member; and a cooperating component manipulatable by the second lever member. The distal end of the gripping component and the distal end of the cooperating component are located an equal distance from the pivotal axis to facilitate the gripping component to grip a portion of the washer. The cooperating component may be viewed as a wedge component as it is shaped to progressively increase the distance between the washer legs in correlation to the position of the first lever member relative to the second lever member until the inner geometery of the washer is sufficient to remove the washer from the projection.

Abstract: A hand tool including a pair of levers each including a handle portion, a jaw portion and a boss portion interconnecting the handle and jaw portions, with the levers being pivotally interconnected for normally permanently intended but relatively movable relationship.

Abstract: A wire twisting tool that includes a pair of jaws for clamping wire ends to be twisted and a removable spin drive unit for imparting rotation to the jaws to effect twisting of the wire ends. The spin drive unit is threadedly attached to a housing that encloses a spiral drive shaft. A pair of shaft engaging elements is mounted in a spaced apart relationship within a tubular carrier that forms part of the spin drive unit. The one end of the carrier is threaded and threadedly engages the housing. One of the shaft engaging elements is fixed to the carrier so that as the shaft is pulled through the drive element, rotation is imparted to the carrier. The other element slidably supports the drive shaft in order to maintain it in a predetermined alignment with respect to the carrier. In one embodiment, the support element is fixed to the carrier whereas in another embodiment it is free to move within the carrier to accommodate a change in pitch in the spiral shaft.

In one position of the latch members one handle member is coupled to one jaw member and the other handle is coupled to the other jaw member. When the latch members are switched, the one handle is coupled to the other jaw member and the other handle is coupled to the one jaw member. Removable tips are secured to each jaw member by an associated clamping plate that includes a corner that diverges from the overall plane of the clamping plate towards the associated jaw member. The fastener for securing the clamping plate is critically so that a positive clamping force is exerted on the tip in a region where it enters the jaw.
