This is even more difficult when a high fence is involved. such as when a ladder must be used to reach its top.  
 OBJECTS OF THE INVENTION It is an object of this invention to provide a fence top rail bender that may be supported on the fence and which. when used. will bend the extending free end of the top rail to the exact desired radius without the necessity of removing the top rail from the fence line post loop caps.  
  A further object of this invention is to provide a comparatively inexpensive fence rail bender that is easy to operate and easy to keep in repair. that is used in cooperation with a conventional cable jack for progressively pulling the extending free end of the top rail to just the desired radius or bend in a single continuous operation while already installed. in part. on at least two supports.  
  Yet a further object of this invention is to provide a fence rail free end bender that will bend the rail free end just the desired amount while in position and also will maintain the bent end in the desired same horizontal plane with the rail portions already supported on and between the posts.  
  A further object ofthis invention is to provide a fence rail end bender that may readily be used on high fences and easily operated from a high ladder because the bender is self-supporting on the fence rail. once it is in position.  
  Still a further object of this snvention is that it may be used in situ on a fence top rail and thus is a desired improvement over prior art pipe benders. such as shown in US. Pat. Nos. 630.848; 907.210; 1.247.728; 2.555.723.

 DETAILED DESCRIPTION OF THE INVENTION There is shown at I0 the in situ fence top rail free end bender of this invention. This bender I0 serves the purpose of bending a fence rail extending free end I2 to the exact desired radius and proper angle to the fence rail 14 already supported in position through line post loop caps 16 and 18 on line posts 20 and 22. and also maintains the bending free end in a horizontal or desired plane.  
  This bender includes a longitudinal abutment pipe member 24 having an abutment and surface 26 somewhat complementary to the surface of the fence pipe 14. Extending from the top of pipe 24 at its abutting end 26 is a supporting hook 28 to extend over rail 14 closely adjacent line post and cap I6, this hook being somewhat complementary to the circumference of the fence rail I4. At the other end of abutment pipe 24. an anchor ring 30 extends in a horizontal plane thereto for attaching a hook 54 and chain 48 thereto.  
  Extending in a substantially vertical plane below abutment pipe 24 is supporting pipe 32 hinged thereto near its non-abutting ring end 30 by a U-shaped bracket 34 and a pivot pin 36 extending through the bracket and the end of supporting pipe 32. The pin 36 may be a bolt and nut if desired. Extending from the opposite end ofsupporting pipe 32 is a Y-shaped guide 38 adjust-ably held against the fence line post 20 by an adjustable chain 40 secured to the top of supporting pipe 32 by a half ring 42 welded thereto near the Y- guide end thereof. The top end ofchain 40 is adjustably attached by a snap hook 44 secured to a half ring 46 welded to the bottom of abutment pipe 24 but spaced from its abutting end 26.  
  Secured to the ring 30 on the end of abutment pipe 24 is a chain 48 which ends in a hook 50. the hook end of chain 48 being looped about fence rail 14 and hooked over itself. The length of chain 48 is such that when hooked over rail I4 it extends a short distance as shown from line post 20 toward line post 22. This completes the description of all novel elements of this bender III.  
  This bender I0 woeks in cooperation with a conventional cable jack 52 having a hook 54. A jack cable 56 arranged to be reeled into the jack 52 extends through jack cable guide finger 58 and ends in a cable hook 60. the hook end of cable 56 being looped about the rail free end I2 and hooked over itself at a point distance from the adjacent line post 20 about two or three times the distance of chain hook on rail 14 from the same line post 20 on the opposite side thereof.  
 OPERATION OF THE INVENTION The rail free end bender I0 is placed in position with the abutting end 26 of abutment pipe 24 against rail 14 closely adjacent the line post 20 but on the side toward the other rail supporting line post 22. The rail 14 extends through the post loop caps 18 and I6 to the extending free end I2. The supporting pipe 32. hinged thereto by bracket 34 and pivot 36, has its Y-shaped guide 38 rest against line post 20. being adjustably supported in position by the adjustable chain 40. Chain 48 is looped over fence rail I4 between the abutted end of abutment pipe 24 and a short distance toward line post 20. the length of chain 48 limiting such distance. Then. the cable jack 52 is hooked on ring 30 and its cable 56 is drawn out and looped over the rail free end 12 a distance from the line post 20 about two or 3 times the distance of chain book 50 about fence rail [4 between the two line posts 22 and 20. Then. operating the cable jack 54 by its jack handle 62 will draw in the fence rail free end I2 as much as desired to provide the desired angle to the fence line post 20. meantime maintaining the bent free end 12 in a desired plane. because the abutment pipe 24 is supported in this desired plane by supporting pipe 32 and its Y-shaped guide against line post 20 and its adjusted chain 40. Then. a line post loop cap is slid over the then extending free end and secured to the next positioned line post in the conventional manner. and the process is repeated as necessary.
