Abstract

In a traverse rod assembly, a draw cord is trained around rollers at opposite ends of the rod with an intermediate portion of the cord also being trained around a tensioning device. The two opposite end portions of the cord are secured to a master carrier which is slidable back and forth on the rod from one end thereof to the middle of the rod. Each end portion of the cord is fastened to the carrier in essentially the same manner with a bight being formed in the end portion of the cord and around a finger projecting rearwardly from the backside of the carrier so that, upon progressing from the end of the cord, the leading end of the bight overlaps the trailing end of the bight thereby holding the trailing end of the cord against the backside of the carrier. From the bight, the cord is trained reversely through a wedge slot formed through the center portion of the carrier adjacent the finger and extends toward the roller at the adjacent end of the rod. The slot is tapered, narrowing upon progressing toward the finger, so that the cord wedges in the slot when tension is applied to the cord thereby anchoring the cord to the carrier.
