  • Patent number: 6679242
    Abstract: An archery bowstring accessory includes a unitary longitudinally elongated body having a head end portion, a tail end portion, and an intermediate section extending therebetween. The intermediate section is configured to extend longitudinally along a bowstring in an orientation which configures the head end portion more proximate a limb end of a bow which receives said bowstring than is the tail end portion. As so received, the head end portion constitutes a speed increasing mass effective to impart increased arrow speed in an arrow shot by said bowstring of said bow than would otherwise occur in an identical arrow shot in the absence of the speed increasing mass. As so received, the tail end portion constitutes a vibration dampening mass effective to impart reduced bowstring vibration in said arrow shot than would otherwise occur in said identical arrow shot in the absence of said vibration dampening mass. Methods are disclosed.

  • Patent number: 6612299
    Abstract: A connector apparatus for removably securing an archery bow accessory to an archery bow. The connector apparatus includes a base that is discrete from the archery bow. The base has a first portion configured for removably securing the archery bow accessory thereon and a second portion spaced from the first portion. The second portion defines a stem that extends axially from the second portion. The stem terminates to define at least one projection extending laterally and generally perpendicularly relative the stem axis. The projection is spaced from the second portion of the base. The invention further includes a discrete body to be removably secured to an archery bow. The discrete body defines an outer surface and bore having a peripheral wall extending from the outer surface to a lowermost elevation spaced from the outer surface. A pair of ledges extend laterally inwardly from opposite sides of the peripheral wall, and the pair of ledges are spaced from the lowermost elevation.

  • Patent number: 5427085
    Abstract: A radiation shielding apparatus for an archery bow includes reflective sheets of material adhereable to a bow limb face. The sheets are comprised of different sizes, including multiple height dimensions and different width dimensions. Each sheet has an outer glossy reflective surface and an inner surface. An adhesive is applied to the inner surface to enable the sheets to be removably adhered to the bow limb face. The glossy surface deflects light radiation away from the bow limb to minimize heating of the bow limb. An archery bow in accordance with the invention includes such sheets.

  • Patent number: 5174268
    Abstract: Eccentric wheels of a compound archery bow are mounted in respective bow limb receiving slots for pivotal movement between a rest draw angular position and a full draw angular position. Each wheel pivot axis extends transversely across the respective wheel receiving slot and is spaced an effective preset slot depth distance A from the respective slot root. Each wheel has a bowstring portion with a peripheral bowstring track formed therein for receiving a section of a bowstring. The peripheral bowstring track has a progressively increasing moment arm radius relative to the respective pivot axis from a rest draw segment to a full draw segment. The moment arm radius from the pivot axis to the full draw segment of the bowstring portion is greater than the effective slot depth distance A to extend the effective length of the respective flexible power limb at the full draw angular position by a distance greater than the slot depth.
