Abstract
Abstract A tensioning device for flexible wires, straps, and the like utilizes a U-shape yoke having parallel legs through which passes a straight portion of a cylindrical rod about which the flexible wire or strap is wound by rotation of the rod to provide the desired tension. One end of the rod is threaded and provided with a securing nut on the outside of the associated yoke leg and a lock nut on the inside of the same leg for controlling the endwise movement of the straight portion of the rod relative to the yoke. The other end of the rod is provided with a bent portion which aids in the rotation of the rod to wind up the flexible member thereon and which is interengaged with a part of the associated yoke leg to hold the rod against unwinding action after the desired tension has been attained. The nuts at the other end of the rod hold this locking position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
213 words
A tensioning device for flexible members such as wires, straps and the like to be tensioned, comprising a generally Ushape yoke adapted to be fastened to a support, said yoke having two spaced parallel legs, there being registering circular openings in said legs, a generally cylindrical rod having a straight portion passing through said opening and rotatable therein and extending outside of said legs, one end of said rod being threaded, a securing nut threaded on said one end of said rod outside of the associated leg, a lock nut threaded on said one end of said rod inside of the associated leg, said nuts being adjustable on said rod to control its position endwise relative to said yoke, means for securing one end of a flexible member to said rod between said legs, there being a bent portion in the other end of said rod at its distal end, said bent portion aiding in the rotation of said rod to wind said flexible member thereon, and said bent portion and the associated leg of said yoke having interengaging parts movable by endwise movement of said rod into locking engagement after said flexible member has been tensioned by winding the same on said rod, which engagement is maintained by adjustment of said nuts.
Claim 2
Dependent Claim
213 words
A tensioning device for flexible members such as wires, straps and the like to be tensioned, comprising a generally Ushape yoke adapted to be fastened to a support, said yoke having two spaced parallel legs, there being registering circular openings in said legs, a generally cylindrical rod having a straight portion passing through said opening and rotatable therein and extending outside of said legs, one end of said rod being threaded, a securing nut threaded on said one end of said rod outside of the associated leg, a lock nut threaded on said one end of said rod inside of the associated leg, said nuts being adjustable on said rod to control its position endwise relative to said yoke, means for securing one end of a flexible member to said rod between said legs, there being a bent portion in the other end of said rod at its distal end, said bent portion aiding in the rotation of said rod to wind said flexible member thereon, and said bent portion and the associated leg of said yoke having interengaging parts movable by endwise movement of said rod into locking engagement after said flexible member has been tensioned by winding the same on said rod, which engagement is maintained by adjustment of said nuts.
Claim 3
Dependent Claim
64 words
A tensioning device as defined in claim 1, wherein said bent portion of said rod makes a U-turn back toward said yoke capable of embracing that portion of the associated yoke leg between the straight portion of said rod and one edge of said associated yoke leg, said bent portion of said rod and said embraced portion of said leg providing said interengaging parts.
Claim 4
Dependent Claim
85 words
A tensioning device as defined in claim 1, wherein said bent portion of said rod makes substantially a right angle bend away from the straight portion of said rod, there being a recess in the outer face of the associated yoke leg extending radially from said opening in said associated leg through which said rod extends, and said recess receiving said right angle bend upon endwise movement of said rod relative to said yoke and providing said interengaging parts for locking said rod against turning.
