Abstract: A tool for removing insulation from electrical wire is provided. The tool includes a set of intersecting arms from which extend blade support members. A pair of replaceable ceramic blades having imbedded resistance heater elements are mounted on the blade support members. The blades are movable toward and away from each other upon application of pressure on the set of intersecting arms to effectuate contact between the blades and the insulation.

Abstract: A packaging technique which have a rotatable member and a stationary member such as an adjustable nut driver of chuck. The package encloses the tool and has at least one transparent section to reveal at least a portion of the tool, and a pair of access openings spaced about 180.degree. to allow manual digital access to the tool. Means are provided to restrain the stationary member of the tool upon rotation of the moveable member to thereby permit a perspective customer to manipulate the tool as well as view it visually.

Abstract: A fluid actuated tool for pressing work pieces with a controlled force and dwell time is provided. The tool includes a fixed jaw and a movable jaw which is movable toward and away from the fixed jaw which arrangement allows a work piece to be squeezed between the jaws. A fluid actuated cylinder is provided which is connected to the movable jaw. The connection includes a coil spring and link and slot arrangement wherein force is transmitted to the work piece between the jaws by compression of the coil spring independent of the fluid force, and the link and slot arrangement allows limited movement of the piston independent of the movable jaw when the jaw meets the resistance of the work piece. The spring thus allows for a dwell time as well as a force independent of the fluid pressure.

Abstract: A hand tool for crimping a work piece by sliding jaw action is provided. The tool has a first handle which fixedly mounts a first jaw at one end thereof and slidably mounts a second jaw in a channel formed therein. A second handle is pivotally connected to the second jaw. A link is pivotally connected to both the first and second handle. A detent device, or piezo electric crystal and read out are provided in the structure to give either a release or a read out response responsive to the generation of a predetermined force load on a work piece.

Abstract: A hand operated crimping tool comprising a crimping head 10 and a pair of operating handles 12 for actuating said crimping head. At least one of said handles includes a force sensing arrangement including detent mechanism for maintaining handle portions 80, 88 in an unloaded position until a predetermined crimping force is applied by the crimping head whereupon the detent mechanism releases to allow slight, relative pivotal motion between the handle portions. The detent arrangement includes a tapered extension post 90 defining a recess 100 and a grip 80 pivotally connected to the post. The grip slidably mounts a spring biased slider 98 which defines a recess, confrontingly aligned with the recess in the tapered post when the grip and extension are in an unloaded position. A detent ball 94 is captured between the confronting recesses. The force exerted by the slider on the detent ball resists pivotal movement between the grip and the extension.
