Abstract: A bow stabilizer having a hollow body with at least one opening and forming a chamber. A plug is removeably mounted within each opening. At least a portion of the plug is positioned between two contact surfaces of a sealing device. The sealing device further has a threaded member rotatably mounted with respect to the plug and mateably engageable with an internally threaded bore formed by a first plate of the sealing device. As the threaded member is rotated, the two plates of the sealing device move towards each other which compresses and deforms at least a portion of the plug. An outer surface of a portion of the plug is enlarged and compressed against an inner surface of the hollow body to form a tight seal that contains a fill within the chamber.

Abstract: An arrowhead having at least one blade, preferably between two to six blades, which are interchangeably mounted in a pivotal or a fixed position with respect to a blade carrying body. A pin is used to retain a corresponding blade in a pivotal or a fixed position with respect to a blade carrying body. When the blade is pivotally mounted a bias force of a retaining member is preferably selected so that each blade remains in a normally closed position during flight or during handling of the arrowhead, but yet responsively and quickly moves to a fully open position upon impact or when a sufficient opening force is applied to the blade. A blunt leading surface of the pivotal blade in its normally closed position presents a convex curve to the target surface thereby insuring good transfer of opening force to the blade when striking the target.

Abstract: An archery vane having a first side with a first surface and an opposing second side with a second surface, the second surface having a roughness greater than the roughness of the first surface. A projection is attached to the first surface. The archery vanes generate rotation of the arrow shaft about its spin axis to provide increased stability of the arrow shaft and improved flight accuracy of the arrow. Arrows having such archery vanes are easily and efficiently manufactured due to the position of the archery vanes on the arrow shaft generally parallel to the spin axis.

Abstract: An improved arrowrest is provided having a rate of motion from a first normal position to a second actuated position is greater than the rate of return motion from the second to the first position. An arrowrest is attachable to a support shaft for the arrowrest. The support shaft is moveable between the first position and the second position. As an arrow shaft discharges over the arrowrest, the support shaft moves in one direction with less frictional resistance than in a return direction.

Abstract: An arrow rest for an archery broadhead having a support shaft extending from a bracket. A first support arm having a first arcuate end is wrapped around the support shaft and is adjustable in a vertical and/or a horizontal direction. A post having a second support arm with a second arcuate end wrapped around the post may extend at an angle from the support shaft. The arrow rest may additionally include a means for positioning the first support arm along an angular path with respect to the bracket.

Abstract: An arrowhead having at least one blade, preferably between two to six blades, which are interchangeably mounted in a pivotal or a fixed position with respect to a blade carrying body. A pin is used to retain a corresponding blade in a pivotal or a fixed position with respect to a blade carrying body. When the blade is pivotally mounted a bias force of a retaining member is preferably selected so that each blade remains in a normally closed position during flight or during handling of the arrowhead, but yet responsively and quickly moves to a fully open position upon impact or when a sufficient opening force is applied to the blade.

Abstract: An archery broadhead having a ferrule body with longitudinal grooves that accept a plurality of fixed and/or pivotal blades. At least a port ion of the ferrule body has a multiplicity of irregularities that form an irregular skin surface having a surface roughness. The irregularities enhance aerodynamic flight characteristics of the broadhead and also reduce frictional drag as the broadhead penetrates a target. The irregularities can be formed by a directional, non-directional or multi-directional set of repeating dimples, grooves, lands, stippling and/or any other suitable structure that forms a pattern, uniform or non-uniform.

Abstract: An arrow rest preferably having three or more flanges that extend outward in a generally radial direction. The flanges are peripherally spaced with respect to each other and form a clearance cutout between flange surfaces that face or oppose each other. The flanges or another suitably shaped body form two or more clearance cutouts that each accommodate a different diameter of a differently sized arrow shaft.

Abstract: An apparatus for adjustably mounting an arrow rest wherein a pivot shaft is mounted within a through bore of a sleeve, so that the pivot shaft can pivot or rotate between a normal rest position and a maximum forward position. The sleeve is mounted with respect to a bracket that is fixed with respect to an archery bow riser. Opposing end portions of the pivot shaft extend beyond corresponding end surfaces of the sleeve. One of the end portions of the pivot shaft is housed within an end cap bore. A spring has one end foot attached or mounted with respect to the end cap and an opposing end foot attached or mounted with respect to the one end portion of the pivot shaft housed within the end cap bore. A pair of keeper elements and a wave washer or other spring element are attached to or mounted with respect to the pivot shaft to significantly reduce horizontal movement or longitudinal play of the pivot shaft with respect to the sleeve and thus of the arrow rest within a corresponding shooting window.

Abstract: A blade-opening arrowhead wherein at least one blade, preferably two blades, are pivotally mounted with respect to a blade carrying body. A bias force is used to urge an engagement member against a corresponding blade. The bias force is preferably selected so that each blade remains in a normally closed position during flight or during handling of the arrowhead, but yet responsively and quickly moves to a fully open position upon impact or when a sufficient opening force is applied to the blade.

Abstract: A bowsight for attachment to a bow. The bowsight has a crosswire frame which is supported by a bracket held to the bow. A pin slide is formed in an inner frame member and has a cylindrical opening. The pins can emit light and are mounted in transparent discs which slide into the cylindrical opening and which are tightened by an Allen screw against a slot in the disc, thereby expanding the disc against the side of the pin slot. The transparent disc gathers surrounding light and transmits or directs the light to the light-emitting pin. A lens or a light-emitting source can be positioned in the cylindrical opening to surround the transparent disc with light. The crosswire frame may be incrementally moved up and down with respect to the bracket by locking a spring-loaded ball bearing in any one of a plurality of detents in the frame. The spring-loaded ball bearing may be forcibly engaged so that the spring is completely compressed thereby locking the ball bearing in a chosen detent.

Abstract: A mounting apparatus having a rod slidably mounted within a longitudinal bore of a housing. The rod has returnable pivoting action and adjustable, returnable plunger action, with respect to the housing.
