   DESCRIPTION 
   The present invention relates to a tool to aide in the bending of rebar (reinforced steel bars) on construction site. The invention is comprised of steel. There is the part that goes into a hitch which can differ based on the size of the hitch. This is made from a 14″ long piece of steel which is 2×2 inches square.
         At the end of this piece there is a welded on rectangle (4.75″×2.5″).   In the middle of this rectangle there is a cylinder welded into the middle which has tow rollers fastened to the middle of it.   Each roller is approximately 1.5″ in diameter.   The space between the roller and the hitch; and the size of a rectangle can vary based on size of tool needed.   Attached to the left side of the rectangle/hitch there is 1.5″ by 1.5″ square welded onto the frame.   Attached to top of this square is and adjustable clamp with spring and bolt tensioner.   There is then another piece which is used as the guide for the rebar. It is made out of welded steel also.   There is support frame which is 1.25″×1.25″ which is 14.15 inches in length.   It is welded onto a 7⅜″×4″ sheet of steel used to hold the rebar in place.   Finally there is a cylinder used to support the beam which is dependent on the size of the rebar the tool is being built for. This is also welded to the sheet of steel.       

   The components work together according to the following steps:
     (1) The hitch portion of the tool goes into the hitch of any vehicle that has a trailer hitch setup. This varies from Class I hitches to Class V hitches.   (2) The consumer then takes the rebar and places it between the hole in the hitch and the cylinder in the middle of the rectangle described above. The rebar then sits down into the cylinder made to aide in the bending of the bar.   (3) The guide rail is then adjusted using the spring tensioned clamp to the height that the customer wants the bend to be.   (4) The rebar is then placed against the rollers and pulled on until the correct angle of the bend is achieved that the customer wants in their rebar.   

   The invention could also be used to bend other types of metal and rods used in the construction of a house or for landscaping. This tool could also be used for bending of conduit for electrical work. 
   The item could be created with different pre-set angles on the item to allow for more precise angle creation. Also the adjustable trailer hitch could be placed in a fixed position so that the length would be set when purchasing the item.
