For Stabilization Thereof Patents (Class 124/89)
  • Patent number: 4660538
    Abstract: The stabilizer has the threaded end of a mounting bolt projecting from a tube. The bolt head is inside the tube. A spring is compressed between the bolt head and a seat bearing against a shoulder surrounding the opening through which the bolt projects. An adjusting nut on the bolt bears against a bumper bearing on the other side of the shoulder. Adjusting the nut adjusts the spring force to vary the effect generally to match the draw weight of the bow. A lead weight is press-fit in the open end of the tube which is closed by a plastic plug or, in the alternative, by an adapter into which a supplemental weight is screwed or a "tracker" is screwed.

  • Patent number: 4607606
    Abstract: A bow mounted quiver includes a storage apparatus for releasably housing a plurality of arrows on one side of the bow and a counterweight mounted on an opposite side of the bow to compensate for the twisting torque produced by the weight of the storage apparatus and the arrows contained therein. Both the counterweight and the storage apparatus are secured to the bow by means of externally threaded shaft members. In a preferred embodiment, one counterweight threadably engages the external threads on the shaft member and is rotatable thereon so as to vary the torque produced thereby. That is, as arrows are removed from the quiver, the counterweight may be rotated clockwise so as to cause its movement toward the bow. As arrows are added to the quiver, the counterweight is rotated counter-clockwise increasing its distance from the bow and thereby increasing the torque produced thereby.

  • Patent number: 4478204
    Abstract: A bow-and-arrow accessory of the type stabilizing a bow when attached thereto has a detachable portion for removal of embedded arrow points, that includes a straight rod with a set-screw equipped weight. The weight is slidable on the straight rod for adjustably varying the moment arm of the weight when the rod is attached to a bow. The weight is also slidable as a hammer against an anvil on a first end of the rod for axially with-drawing an embedded arrow point when the second end of the rod is attached to an embedded arrow point. The hammer action results in axial withdrawal and so eliminates dangers of damaging arrow points by wrenching, rocking or prying, and lowers risk of slipping and straining injury to the person removing an embedded arrow point.
