Compound bow cable tension adjuster

摘要

Apparatus for adjusting the angular position of the pulleys in a compound bow is mounted on each of the pulleys, not between the pulleys. The apparatus consists of either rotatable or slidable elements which are mounted on the pulleys. The tension cables contact these elements. The elements are designed such that movement of the elements moves the tension cables and causes changes in tension in the tension cables. This causes rotation of the pulleys, thus changing the angular position of the pulleys. The rotatable elements consist of either eccentrically mounted or shaped cams. The tension cables extend around the cams and are anchored to the pulleys. The rotation of the cams causes changes in tension in the tension cables, thus changing the angular position of the pulleys. The slidable elements consist of either a set screw or a sliding plate. In the case of a set screw, one end of the set screw contacts the tension cable and the tension cable is anchored to the pulley. Movement of the set screw changes tension in the tension cable, thus changing the angular position of the pulley. Alternatively, a tension plate is slidably attached to each pulley and is moved toward or away from a fixed plate by rotation of a thumb screw. The tension cables extend around the tension plates and are anchored to the pulleys. Movement of the tension plates changes the angular positions of the pulleys.
