Tension control arrangement for a bolt

Image Number 8 for United States Patent #6715975.

A tension control arrangement including a plurality of cams disposed about an opening that accommodates a bolt to which a nut is intended to be secured. Each of the cams has a contoured outer surface, and each of the cams is rotatably supported such that the contoured outer surface operatively engages both the base and a contact member interposed between the cam and the nut. A lever assembly is operatively coupled to the cams, such that movement of the cams is substantially restricted to rotational motion from a first position in which the nut is engaged with the bolt and tightened by hand until it is seated against the contact member, to a second position in which the bolt is elongated to achieve a predetermined bolt tension.
