Abstract
Abstract A cable bender comprising a pair of cable holding cradles pivotally connected together at adjacently positioned inner ends and wherein no restraint is applied to the cable in the region of the cable where it is bent. Wrench members are adapted to be connected to the cradles at opposite ends of the bender and bending is achieved by applying a torque and counter torque, respectively, to the cradles by the wrench members.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A cable bender comprising: first and second cradles, each having a bottom tubular shaped interior and a tubular surface extending upward and forming a top interior surface at one end; coupling means extending from and under the opposite end of each said cradle for rotably interconnecting said cradles whereby said cradles may be relatively rotated about a common axis adjacent said opposite ends of each said cradle; and torque means extending from said one end of each said cradle and including means for applying a torque and counter torque to said cradles about an axis parallel to said common axis whereby a cable positioned in and held by said cradles is bent about said common axis.
Claim 2
Dependent Claim
116 words
A cable bender comprising: first and second cradles, each having a bottom tubular shaped interior and a tubular surface extending upward and forming a top interior surface at one end; coupling means extending from and under the opposite end of each said cradle for rotably interconnecting said cradles whereby said cradles may be relatively rotated about a common axis adjacent said opposite ends of each said cradle; and torque means extending from said one end of each said cradle and including means for applying a torque and counter torque to said cradles about an axis parallel to said common axis whereby a cable positioned in and held by said cradles is bent about said common axis.
Claim 3
Dependent Claim
24 words
A cable bender as set forth in claim 1 wherein the upper region of said opposite end of each of said cradles is open.
Claim 4
Dependent Claim
23 words
A cable bender as set forth in claim 2 wherein at least the interior edges of said opposite end region edges are tapered.
Claim 5
Dependent Claim
35 words
A cable bender as set forth in claim 3 wherein the axis of said coupling means is in the range of one to three inches from the axis of the tubular interior of said cradles.
Claim 6
Dependent Claim
36 words
A cable bender as set forth in claim 3 wherein the tubular surface in the end region of said opposite end of a said cradle extends upward to partially close one side of a said cradle.
Claim 7
Dependent Claim
23 words
A cable bender as set forth in claim 3 where each said torque means is engageable from either side of said cable bender.
Claim 8
Dependent Claim
40 words
A cable bender as set forth in claim 6 wherein at least one of said torque means comprises a receptacle extending from side to side, parallel to said common axis, and is adapted to be engaged by a removable handle.
Claim 9
Dependent Claim
48 words
A cable bender as set forth in claim 7 further comprising a said handle and wherein said handle includes ratchet means for applying a bending torque to the torque means of one of said cradles when a counter-torque is applied to the torque means of the other cradle.
Claim 10
Dependent Claim
38 words
A cable bender as set forth in claim 6 wherein said coupling means comprises a collar connected to each of said cradles and a pin extending through said collars and supporting said collars in side by side relationship.
