The spring loaded ball may be tightened so that the spring is completely compressed thereby locking the ball in a chosen detent.

Abstract: An adjustable archery sight assembly which may be secured to an archery bow for use in target shooting includes a generally horizontal bar removably and slidably secured to the bow, a generally vertical arm removably secured to the horizontal bar at a proximal end thereof, a block slidably mounted to the vertical arm; and a sight pivotally and slidably secured to the block. The vertical arm defines a generally vertical path defined by a depression formed in the vertical arm and having beveled edges. The block slides within said path and has ears which have beveled edges formed complementary to the bevelled edges of the depression. The use of the parallel bevelled edges keeps the block, and hence the sight, in alignment when the sight is moved along the path of the vertical arm.

Abstract: An improved archery sight and arrow rest combination incorporates the positioning of the sight generally vertically above the arrow rest. Positioning of the sight generally vertically above the arrow rest eliminates any undesirable effects from archer induced torque on the bow handle. Both the sight and rest are positioned rearwardly of the bow handle. Should the bow handle be twisted due to archer induced torque, both the sight and arrow rest will move to effectively the same position. Thus, when the archer sights along the sight member, the arrow will be pointing in the same direction. In the prior art, the arrow rest was often behind the bow handle with the sight in front of the bow handle. When archer induced torque occurred, the archer would be sighting along one line, while the arrow would actually be aimed along another. The present invention has addressed this problem.

Abstract: A bow hunting sight has a base defining a front, a back, sides, a top, and a bottom. At least one hole extends between the front and back of the base. The base further has at least one bore which extends generally perpendicular to, and intersecting with, the front-to-back hole. A carriage is pivotally and slidably received in the bore and is exposed through the front-to-back hole. The carriage has a threaded bore extending longitudinally therethrough through which an aiming pin is threadably received. A single set screw is used to lock the aiming pin against both pivotal and axial movement. The set screw is movable between a locking position in which the set screw urges the carriage inwardly to urge the aiming pin against a surface of the front-to-back hole to prevent both pivotal and axial movement of the pin and an unlocked position in which the carriage may move axially in the bore such that the aiming pin may be moved both pivotally and axially.

Abstract: An archery bow sight apparatus has a single front, horizontally adjustable, target sight pin and a plurality of rear, horizontally and vertically adjustable, yardage sight pins, each of the mar pins designated for a different, specific shooting distance. The sight apparatus is initially adjusted (or sighted in) by first pulling the bow string back until it touches the archer's cheek, at which point the single front pin is slid horizontally in or out to the point where it is centered on the target. The front pin is then locked into this position. The rear yardage sight pins are each individually adjusted for a different specific distance by selecting a target a specific distance away and aligning the first of the rear distance pins with the front target pin. Shooting accuracy is then increased by adjusting the position of the first rear pin to the right or left (horizontally) and up or down (vertically) by shooting arrows and then slightly sliding the rear pin appropriately based on where the arrows hit.

Abstract: A light archery sight using a spot of light reflected on a transparent window for aiming purposes.

Abstract: An archery bow sight installable within the bow string provides a relatively large sight window in order to allow an archer to acquire a target easily, and to preclude the need for angular compensation of the sight for the angle of a drawn bow string. While the sight window is relatively large and deep, the target alignment portion along the window interior periphery provides accurate target alignment without blocking any portion of the sight window, thus making the present sight useful in both normal and low light conditions. The sight may be formed as a monolithic, unitary component, or alternatively may be formed as separate upper and lower components with left and right strands of the bow string serving as the sides of the sight window. The sight also provides for alignment to preclude twisting due to the tension of the drawn bow string, as well as providing for securing the sight longitudinally within the string in order to prevent slippage and resulting elevational misalignment of aim.
