Abstract: A wire gripping apparatus for use with a tensioning device to stretch wire in preparation for mounting to fence posts. An elongated rod has a slotted wire locating plate mounted at its forward end, a support plate extending along the rod and a clamping member movable axially along the rod from its rearward end toward the rear end of the support plate. The support plate has a rearward edge provided with a slot which faces the clamping member. The wire is placed within the slot in the wire locating plate, bent or crimped into the slot in the support plate, and the clamping member is axially moved along the rod and into contact with the rearward edge of the support plate to capture the wire. The wire clamping apparatus is connected by an eyelet at the rear end of the rod to a suitable tensioning device, such as a come-along or winch for stretching the wire. Slot openings in the locating and support plates are radially spaced at 90.degree.

Abstract: A push-in electrical wire connector for interconnecting at least two electrical wires includes a housing and a wire-clamping member mounted therein. The clamping member has apertures through each of which a respective conductor is insertable, and a resilient clamping portion extending lengthwise of the housing in an overlying relationship with an interior support wall. Due to its resilience, the clamping portion deflects from an initial position to a deflected position in which the clamping portion electromechanically engages and constantly urges the inserted conductor against the support wall.

Abstract: Cable ends of a compound bow are adjustably and securely anchored by an attachment member pivotally mounted adjacent the bow eccentric wheels. The attachment member body is of substantially constant thickness and includes a plurality of openings therethrough parallel to the opposite planar faces of the body and angularly offset relative to one another to define a circuitous cable pathway. An end section of the cable is secured by insertion of a threaded lock device through an edge wall of the body into an enlarged transverse anchor bore allowing radial distortion of crimping of the cable end section.
