  • Patent number: 6634110
    Abstract: A bow sight provides horizontal, vertical and at least one rotational adjustment mechanism which provides continuous movement of the sight ring without having to release a locking mechanism and still not allow unintentional movement of the sight ring. The sight has a plurality of sight pins having illuminated tips located at spaced-apart locations along a vertical sight line which extends across the sight ring. First adjustment mechanisms allow the sight pins to be rotated in order to set the location of the tips along the sight line and second adjustment mechanisms allow the sight pins to be moved along their longitudinal axes to align them with the sight line after they have been rotated. The sight also includes particular horizontal and vertical micro adjustment mechanisms which allow very small movements of the sight ring in the horizontal and vertical directions without having to release a locking mechanism.

  • Patent number: 5809984
    Abstract: A cable adjuster for individually adjusting the cable ends of a split cable on a compound archery bow has a body with a medial slot located in it which fits over the end of the pin which journal the bow cams. The slot is configured so that the body can rotate on the pin and be slid toward and away from the center of the bow. A retainer secures the body rotatably on the pin. A button attached to the body releasably engages a loop located at the cable ends. A notch is located between the body and the button to seat the cable loop on the device. The button and notch are angled with respect to the body such that when a force which is applied to the cable, the elongate axis of the body remains normal to the axis of the pin so that the body can rotate on the pin without binding. A set screw extends through the top end of the body into the slot where it contacts the top of the pin when force is applied to the cable.
