Abstract
The tool includes a housing and a pair of forwardly projecting tubes respectively containing slidably mounted rods, one for use in tensioning a lock wire and the other for use in crimping a ferrule onto the lock wire. Camming structure moves the rods forwardly and rearwardly. First, the tensioning rod snaps back under the control of a spring to tension the wire. Then, the ferrule is crimped by forward movement of the other rod.
Claims75
A tensioning and crimping tool comprising means for tensioning a wire, holding and crimping means for holding a ferrule and for crimping the ferrule onto the wire after the wire has been tensioned, means for operating said tensioning means and said crimping means, said holding and crimping means including a movable member positionable to hold the ferrule and then to crimp the ferrule in response to said operating means, and hand-operated means for actuating said operating means.
A tensioning and crimping tool comprising a housing, a tensioning tube projecting forwardly from said housing, a tensioning rod slidably mounted in said tensioning tube, means on the front end of said tensioning rod for gripping a wire, tensioning-rod operating means for moving said tensioning rod rearwardly to tension a wire, a crimping tube projecting forwardly from said housing and being substantially parallel to said tensioning tube, means at the front end of said crimping tube defining a ferrule chamber, a crimping rod slidably mounted in said crimping tube and extending from said chamber to said housing, crimping-rod operating means for moving the front end of said crimping rod into said chamber and thereby crimp a ferrule therein, actuating means coupled to both of said operating means, and hand-operated means for actuating said tensioning-rod operating means and said crimping-rod operating means.
A tensioning and crimping tool comprising a housing, a tensioning tube projecting forwardly from said housing, a tensioning rod slidably mounted in said tensioning tube, means on the front end of said tensioning rod for gripping a wire, tensioning-rod operating means for moving said tensioning rod rearwardly to tension a wire, a crimping tube projecting forwardly from said housing and being substantially parallel to said tensioning tube, means at the front end of said crimping tube defining a ferrule chamber, a crimping rod slidably mounted in said crimping tube and extending from said chamber to said housing, crimping-rod operating means for moving the front end of said crimping rod into said chamber and thereby crimp a ferrule therein, and actuating means mounted on said housing for rotation about an axis substantially parallel to the axes of said tensioning and crimping rods and being couple to both of said operating means.
A tensioning and crimping tool comprising a housing, a tensioning tube projecting forwardly from said housing, a tensioning rod slidably mounted in said tensioning tube, means on the front end of said tensioning rod for gripping a wire, means for rearwardly biasing said tensioning rod, tensioning-rod operating means having a first portion restraining rearward movement of said tensioning rod and having a second portion for releasing said tensioning rod to cause tensioning of said wire, a crimping tube projecting forwardly from said housing and being substantially parallel to said tensioning tube, means at the front end of said crimping tube defining a ferrule chamber, a crimping rod slidably mounted in said crimping tube and extending from said chamber to said housing, crimping-rod operating means for moving the front end of said crimping rod into said chamber and thereby crimp a ferrule therein, and actuating means mounted in said housing for rotation about an axis substantially parallel to the axes of said tensioning and crimping rods and being coupled to both of said operating means.
A tensioning and crimping tool comprising a housing, a tensioning tube projecting forwardly from said housing, a tensioning rod slidably mounted in said tensioning tube, means on the front end of said tensioning rod for gripping a wire, means for rearwardly biasing said tensioning rod, tensioning-rod operating means having a first portion restraining rearward movement of said tensioning rod and having a second portion for releasing said tensioning rod to cause tensioning of said wire, a crimping tube projecting forwardly from said housing and being substantially parallel to said tensioning tube, means at the front end of said crimping tube defining a ferrule chamber, a crimping rod slidably mounted in said crimping tube and extending from said chamber to said housing, crimping-rod operating means for moving the front end of said crimping rod into said chamber and thereby crimp a ferrule therein, and handle means pivotally mounted on said housing and coupled to said tensioning-rod operating means and to said crimping-rod operating means.
