| 1. An archery bow sight for use by an archer holding a bow with a first hand, fully drawing an arrow mounted in the bow to
an anchor point with a second hand to establish a draw length, and aiming with a sight eye, the bow sight comprising:
(a) a frame adapted for mounting onto a bow;
(b) a rear sight attached to the frame, the rear sight being movable vertically and being positioned a first horizontal distance
from the archer's sight eye;
(c) a front sight attached to the frame, the front sight being movable vertically, being positioned a second horizontal distance
from the archer's sight eye, and being further positioned in a line of sight from the archer's sight eye through the rear
sight;
(d) a linkage between the rear sight and the front sight for simultaneously moving the rear sight a first vertical distance
and the front sight a second vertical distance to correspond to targets of varying distance; and
(e) a means for initially adjusting the sight to conform to a draw length of a particular archer to ensure that the ratio
of the first vertical distance divided by the second vertical distance equals the first horizontal distance divided by the
second horizontal distance, the means comprising either an adjustment to the linkage to change the ratio of the first vertical
distance divided by the second vertical distance or an adjustment to the horizontal position of the rear sight or front sight
to change the ratio of the first horizontal distance divided by the second horizontal distance;
such that the rear sight and the front sight remain in a line of sight from the archer's sight eye to targets of varying distance.
