"textContent": "A gearless binder has a main tube with internal threads at opposed open ends. The gearless binder has a pair of semicircular threaded shafts threadably received in the opposed open ends such that, when the shafts are connected by hooks to a chain and prevented from rotation, the rotation of the tube by a gearless mechanism causes the shafts to simultaneously move inward relative to the tube increasing tension on the opposed hooks to secure a load. A spring disposed around the tube provides a gripping force on the tube to allow for rotation of the tube in a first direction to cause the threaded members to enter the tube to secure a load.",
