Abstract: The present invention is a limb bolt assembly for a recurve bow. The recurve bow has an upper limb, a lower limb, and a center riser with an upper end and a lower end each having a U-shaped slot for receiving a proximal end of a respective one of the upper and lower limbs. The limb bolt assembly includes an elongated threaded bolt mounted across the U-shaped slot, an index plate for indexing a rotational position of the bolt, a sleeve located inside the U-shaped slot and threadedly engageable with the elongated bolt and further engaging with the proximal end of the respective one of the upper and lower limbs, an end attached to the end of the bolt, and a plug mounted at a bottom opening of the U-shaped slot. The sleeve has an enlarged flange with straight rim portions for engagement with the inside sidewalls of the U-shaped slot from rotating inside the U-shaped slot, so that the sleeve can be driven along the bolt by rotating the bolt to adjust the poundage and tiller of the recurve bow.

Abstract: The present invention apparatus is a novel and unique combination of a damping member adapted to an indexed scale fastener for use with an archery bow. The indexed scale fastener and the damping member can be used together or separately. The damping member can be used at locations on the archery bow which are remote from the indexed scale fastener. The concept is to have the indexed scale fastener adapted to the conventional threaded openings where the prior art hex screws are located. A user can screw the indexed scale fastener to the archery bow and measure the poundage applied to the archery bow by simply reading the scale provided on the indexed scale fastener. The damping member can be threadedly mounted to the indexed scale fastener or to the archery bow, where the damping member absorbs the vibrations and shock in both the longitudinal and lateral directions caused by releasing of the arrow from the archery bow.

Abstract: The present invention is a novel and unique adjustable plunger for an archery bow riser. The present invention utilizes the archery bow riser threaded aperture common to nearly all modern conventional archery bows. It provides a considerably improved method for tuning a plunger for balancing the side pressure from an arrow, so that the tuning process can take a matter of minutes instead of hours. The present invention includes an index micro adjustment which is a linear tension indicator scale for tightening or loosening the tension on the biasing spring. The present invention is fully adjustable in a longitudinal direction.
