An improved band seal clamp for clamping cylindrical members, for example, automotive or truck exhaust systems, is disclosed which features clamping bars at each end of the band. Upon tightening of bolts, at least one end of the band is wrapped up about an axis outside of and parallel to the axis of the tube, so as to tighten the band clamp.

A band seal clamp for exerting a compressional force upon a cylindrical member when tightened, said clamp comprising: a relatively wide, flat, elongated band of metal, said band having first and second ends, each of said ends being adapted to be assembled to and mate with a force bar member, the ends of said bands and the respective force bars having corresponding holes formed therein for passage therethrough of headed bolt means, at least one of said force bars having a reaction surface disposed at an angle other than the perpendicular to the axis of said bolt means, and said bars being shaped such that the outer portions of the assemblies of said force bars and the ends of said bands disposed away from said cylindrical member contact one another at initial assembly thereof, such that upon further tightening of said bolt means, an unbalanced force is exerted upon said at least one force bar by the head of said bolt causing it to rotate about an axis external to said cylindrical member to be clamped, wherein the shapes of the holes in said force bar which is rotated vary from a generally circular cross-section sized to fit said bolt means at an end for entry of said bolt means to a substantially oval cross-section at the end from which said bolt means exits, so that upon tightening of said bolt means said force bar is substantially rotated generally about an axis passing through the point at which said bolt means contacts said hole at a point on the generally circular portion of its cross-section.
