Abstract:
A stabilizer for long cylindrical work pieces comprising:a) a mounting platform, b) a mover connected to the platform and the mover has a line of action that is perpendicular to the centerline of a cylindrical work piece and the mover serves to move a central pivot along the line of action towards and away from the centerline of the work piece, c) A first arm and a second arm pivotally connected to the mounting platform, and the arms are equally spaced to either side of a plane defined by the centerline of the work piece and the line of action of the mover and the arms project from the mounting platform in the direction of the work piece, and the arms have a length approximately equal to the distance between the platform and the work piece, d) A first link and a second link pivotally connected to the central pivot and the first link is pivotally connected to the mid-length of the first arm and the second link is pivotally connected to the mid-length of the second arm and the links are angled from the pivot towards the platform, e) a first roller carrier pivotally connected to the first arm near the free end of the arm and on the side of the arm nearest the centerline of the work piece and a second roller carrier pivotally secured to the second arm near the free end of the arm and on the side of the arm nearest the work piece and the first and second carriers have rotatably secured thereto at least two rollers and the rollers are positioned on the carriers so that when the outside perimeters of the rollers are in contact with the work piece the carriers will pivot so that the rollers are in contact with the work piece at equal distances from the centerline of the work piece, and f) the axes of rotation of the rollers and the pivot axes of the pivots are parallel to the longitudinal centerline of the work piece.
