Abstract
An automatic arrow positioning device for attachment to an archery bow. The device includes a V-shaped bale which is mounted rotatably within a generally semi-circular shaped housing. The housing is attached to a bracket which, in turn, is attached to the bow at, for example, the riser of the bow. One arm of the bale is attached to one end of an actuator. The other end of the actuator is attached to the inner end of a cable which extends to and is connected to the timing cables of the bow. Drawing of the bowstring causes the timing cables and actuator to pull the bale into correct position for the arrow to be shot.
Claims2
An automatic arrow positioning device for attachment to an archery bow having a riser, a bow string, timing cables, and a cable guard bar, said bowstring and riser defining a bow plane along which an arrow is expelled, said arrow positioning device for automatically supporting said arrow in a shooting path in said bow plane when the bow is drawn, comprising:
- a housing member, said housing member including two upwardly extending sections, one on each side of said bow plane;
- a bearing means at the upper end of each upwardly extending section, said bearing means located at approximately the height of said shooting path, and in a plane perpendicular to said bow plane;
- a bracket means for attaching said housing member to the bow, said bracket means including a generally vertical plate for attachment to a side of said bow riser, said bracket means including an aperture in line with said bearing means;
- an arrow supporting bale means, having a central generally V-shaped section for receiving an arrow, and first and second generally horizontal sections, one on each side of the central section, each horizontal section pivotally supported in a respective bearing means, and said second horizontal section additionally passing through said aperture in said plate;
- an activating member having first and second ends, said second horizontal section of said bale means, after passing through said aperture in said plate, anchored to a first end of said activating member;
- an actuating cable having first and second ends, a first end of said actuating cable being connected to the second end of said activating means, and a second end of said actuating cable being connected to the timing cables;
- whereby, as the bowstring is drawn, the timing cables will move, and such movement will be transmitted through the actuating cable to the bale, causing the V-shaped section to rotate upward to support an arrow in the shooting path, and when the bowstring is released, the V-shaped section will rotate downward to avoid contact with the arrow as it is released.
