A tool for tensioning safety cable to a predetermined tension limit includes a reciprocally rotatable wheel mounted for rotation about a point on the tool for incrementally advancing the cable. A gear assembly is coupled to the rotatable wheel and has at least one driven gear connected to affect rotation of the wheel. A power actuator is coupled to the gear assembly and adapted for affecting reciprocal rotation of the at least one driven gear to thereby affect rotation of the wheel. The cable is attached to the wheel after being drawn through bolts to be restrained by the cable. The tool includes apparatus for terminating the cable to restrain it with the desired tension.

Power operated safety cable tool

A tool for tensioning safety cable to a predetermined tension limit and for automatically terminating the cable when the predetermined limit is reached. The tool comprises a rotatable wheel mounted for reciprocating rotation about a point on the tool for incrementally advancing the cable during a drive stroke and a toggle assembly operatively connected to the rotatable wheel for affecting its reciprocal rotating motion. A tension setting mechanism operatively coupled to the toggle assembly for inhibiting rotation of the rotatable wheel when tension on the cable is greater than a preselected value. A clamp is operative in response to inhibited rotation of the rotatable wheel for terminating the cable by crimping a ferrule to the cable while simultaneously severing a free end of the cable.

A clamp is operative in response to inhibited rotation of the rotatable wheel for terminating the cable by crimping a ferrule to the cable while simultaneously severing a free end of the cable. The tool includes an elongated nosepiece having an aperture for receiving the ferrule and passing the cable therethrough. The nosepiece includes an inner flange which fits within a formed recess in the tool and is spring-loaded into the recess. The nosepiece can be depressed out of the recess enabling rotation of the nosepiece about its elongate axis so as to position the aperture at selected angular positions.

A tool for tensioning safety cable to a predetermined tension limit and for automatically terminating the cable when the cable has been tensioned to the predetermined limit. The tool includes apparatus for grasping and pulling the cable to the predetermined tension limit and apparatus for automatically crimping a ferrule onto the cable when the predetermined tension limit is reached. The crimping apparatus is operative to sever a free end of the cable concurrently with crimping of the ferrule.

A calibration tool comprises two relatively movable elements. A compression spring is operatively positoned between the first and second elements for resisting closure of the elements with respect to each other. Displacement of the first element is determined with respect to the second element when the spring is compressed by a predetermined pressure. A connecting element, such as a band, is coupled to the calibration tool and to the tensioning apparatus such that actuation of the tensioning apparatus causes the band to effect relative movement of the first and second elements whereby the force exerted by the tensioning apparatus is determined.

Method and apparatus for calibrating a tension tool

A crimping or rollover tool for an end of a metal band used to secure a metal braid to an electrical conductor is formed in a plier-like tool having a guide for accurately locating the tool and a pivotable crimping element operable to effect crimping of the band end without loosening of the band. The guide is slidingly coupled to a jaw of the tool with the crimping element pinned to the guide. Closing of the tool jaws causes rotation of the crimping element to bend the band end over a band buckle without pushing the band end backwards through the buckle.

Rollover tool for ends of metal bands

A banding tool for tightening a band about a woven metal braid portion of an electrical cable about a tubular termination sleeve portion of an electrical connector. The tool comprises a band tension limit which can be adjusted while the tool is coupled to a test device, such as a strain gauge. The tool includes a shuttle mechanism for incrementally advancing the band through the tool during a forward stroke. The shuttle mechanism is mechanically coupled to a pivotally mounted handle by way of an overcenter toggle mechanism. The overcenter toggle mechanism is coupled to a spring tensioning assembly, which includes a plurality of spring members, such as Belleville washers, disposed near the rear of the tool. An adjustment screw on the rear cover portion of the tool allows the spring tension of the spring members to be adjusted. Once the band tension limit is reached, the overcenter toggle mechanism locks the handle in its closed position, thereby preventing further movement of the shuttle mechanism. A lever mechanism on the tool is actuated to bend the band at approximately a 90.degree. angle with respect to the buckle to maintain the tension in the band. The lever is operated in a reverse direction to shear the extra band at the termination.
