Portable device for straightening out tubes

A portable device for straightening out tubes, said device comprising:

• a beam having a first end and a second end;
• a first bearing member pivotally mounted onto said first end of said beam and movable relative to said beam;
• a second bearing member mounted onto said second end of said beam and movable in a transverse direction relative to a center line axis of said beam;
• a third bearing member;
• a handle transversely movably mounted onto said beam between said first and second ends, said handle having a top portion and a base portion, said base portion of said handle carrying said third bearing member, said top portion of said handle being located on said beam opposite said first, second and third bearing members, said first, second and third bearing members being arranged so as to allow a tube to be contacted on a first side by said first and second bearing members and to be contacted on a second side opposite to said first side by said third bearing member;
• and
• a jack fastened to said beam for actuating said first bearing member to be movable with respect to said beam, said jack controlling the motion of said first bearing member in removing the curvature of the tube while said second and third bearing members retain the tube, said jack comprising a rod movable in a direction parallel to said center line axis,
• said first bearing member comprising a roller which contacts the tube, a tie-rod and a link, said link having a first end pivotally connected with said rod of said jack and a second end opposite to said first end of said link being pivotally connected to a first end of said tie-rod at a pivot point, said tie-rod being pivotally connected to said beam at a second end of said tie-rod opposite to said first end of said tie-rod and carrying said roller at the pivot point at said first end of said tie-rod.
