Bow sights and methods of making and using the same

In a bow sight for an archery bow having an elongated support member mounted on said bow and extending in the general direction of the target, and a sight assembly carried by said elongated support member, said sight assembly including a housing disposed generally vertically, a lead screw mounted at its ends on the housing and spaced therefrom between said ends, a sight block mounted for translation along and with respect to said lead screw, and a yardage guide mounted on said sight assembly housing substantially parallel to said lead screw, the improvement comprising a marker, mounted on said sight block for selective adjustment relative to said sight block in a direction substantially parallel to said lead screw and having an indicator in correlative position with said yardage guide, said marker being in the form of an L-shaped rod, said sight block having a shallow groove in it parallel to the lead screw axis, one of the legs of the L-shaped rod being seated in said groove and the other extending to a point adjacent said yardage guide, and means carried by said sight block for holding said marker in chosen position, said housing having an elongated recess forming a yardage guide seat parallel to the lead screw, said yardage guide being in the form of an elongated self-supporting strip of a shape complementary to that of the said seat and selectively removably seated therein, and means, carried by said housing, for locking said strip in said recess.

In a bow sight for an archery bow having an elongated support member mounted on said bow and extending in the general direction of the target, and a sight assembly carried by said elongated support member, said sight assembly including a housing disposed generally vertically, a lead screw mounted at its ends on the housing and spaced therefrom between said ends, and a sight block mounted for translation with respect to said lead screw, the improvement comprising a sighting rod assembly mounted in said sighting block at right angles to the axis of said lead screw, said sighting rod assembly comprising a tubular, open-ended sight rod housing non-rotatably mounted in a passage in said sight block transverse to the axis of said lead screw and means for selectively releasably locking said housing against translation therefrom;

• a bushing mounted in said housing against rotation but for translation with respect thereto;
• a sighting rod extending through said bushing and locked against movement with respect thereto, said sighting rod having a sight marker end projecting from one end of said housing and a threaded shank portion projecting from the opposite end of said housing;
• a spring, caged between said bushing and a shoulder in said housing, biasing the said bushing, hence the said sighting rod in a direction toward the sight marker end of the housing, and an internally threaded knob threadedly engaging the projecting threaded shank of said sighting rod and bearing against an end of said sight rod housing whereby rotation of the said knob produces translation of said sighting rod and bushing with respect to said sight rod housing.
