Abstract: A high speed gill box having an upper head and lower head each of which contains a compliment of individual unconnected faller bars constrained to move in a smooth closed loop path. Each head is constructed to engage the associated faller bars outside of the pinned area to guide the faller bars through the closed loop path. Cam tracks are provided outside of the faller bar guide paths for engaging a crank arm extending away from the main pinned portion of each faller bar to provide proper orientation as the faller bar moves along its fixed path. Sprocket drives are provided in each head for engaging some of the faller bars and pushing them along the closed loop path. The pushed faller bars, as they exit the drive sprockets, push the faller bars ahead of them through the closed loop path. The drive sprockets are mounted at one end of the drafting zone while idler sprockets are mounted at the other end of the drafting zone to facilitate movement of the faller bars from the drafting zone.
