ABSTRACT:
An adjustable tensioning device for stays, rigging, guides and the like, includes an anti-separation member intermediate two adjusting members which are threadably engaged with two threaded members which are themselves threadably engaged with the anti-separation member on opposite sides thereof. A moveable member is associated with each adjusting member and moves correspondingly because of its location between the adjusting member and a restricting member. Each moveable member is connected to an associated attachment receiving element by a number of connecting members moveably engaged with the anti-separation member such that the anti-separation member is intermediate the adjusting member and the attachment receiving element. The anti-separation member may incorporate a yieldable compensator such as a spring or hydraulic cylinder in which case the anti-separation member. In either event a locking device may be included to hold a desired tension adjustment.
