Abstract
In a cable and wire-cutter comprising first and second handles pivoted on one another, a first cutting jaw formed on the first handle and a second cutting jaw pivoted on the first handle; two toothed drive connections are provided between the second cutting jaw and the second handle and work consecutively and with differing multiplying ratios according to the power requirements needed until a cable or wire rope is enclosed on all side by the jaws and thereafter to cut the cable or wire rope.
Claims4
A cable and wire-rope cutter comprising first and second handles pivoted on one another, a first cutting jaw formed rigidly on said first handle, a second cutting jaw pivoted on said first handle, and tooth means operatively connecting said second handle with said second jaw, wherein said tooth means comprise two tooth elements disposed on said second handle one of which is attached to the second handle and the other being formed integral therewith, one of said tooth elements engaging said second jaw for moving it from a position in which it is spaced to a maximum extent from said first jaw into a position in which said second jaw is enabled to cooperate with said first jaw for enclosing a cable or wire rope on all sides, and the other of said tooth elements thereafter engaging said second jaw for moving it past said first jaw, whereby said first and second jaws are enabled to cooperate with cutting said cable or wire rope, said tooth elements having differing multiplying ratios respectively corresponding to the differing power requirements for enclosing and for cutting said cable or wire rope.
A cable and wire-rope cutter comprising first and second handles pivoted on one another for rotation towards and away from one another over a total path of rotation of more than 100.degree., a first cutting jaw formed rigidly on said first handle, a second cutting jaw pivoted on said first handle, the axes of rotation of said handles and of said jaws being parallel, tooth means operatively connecting said second handle with said second jaw, said tooth means including first and second driving tooth elements disposed adjacent to one another in the direction of said axes of rotation on said second handle with said first driving tooth element being attached to said second handle and the second driving tooth element being formed integral with said second handle, said tooth means further including first and second driven tooth elements disposed adjacent to one another in the direction of said axes of rotation and said second jaw with said first driven tooth element being attached to said second jaw and the second driven tooth element being formed integral with said second jaw, said first driving tooth element first cooperating with said first driven tooth element for moving said second jaw through an angle of about 12.degree. to 36.degree. when said handles are moved towards one another over about 8.degree. to 16.degree. of their said path of rotation, from a position in which said second jaw is spaced to a maximum extent from said first jaw into a position in which said second jaw enabled to cooperate with said first jaw for enclosing a said cable or wire rope on all sides, thereby deforming the cross-section of said cable or wire rope, and said second driving tooth element then cooperating with said second driven tooth element for moving said second jaw past said first jaw through an angle of at least 40.degree. more when said handles are moved towards one another over the remainder of their said path of rotation, whereby said first and second jaws are enabled to cooperate for cutting said cable or wire rope.
