  • Patent number: 9574842
    Abstract: An archery bow/crossbow press and method provides operation to various bow designs including bows with past parallel limbs or having limbs with sharp curvatures using collectively connected bow limb supports to engage the outer face of a bow limb for compression; each bow limb support configured with at least one upper and at least one lower support arm wherein each support arm comprises bow limb contact areas that may include various shapes adaptable to engage a bow limb or limb components; each support arm may be positioned against a bow limb independently or collectively with each other; and, when the bow limb supports are positioned collectively on the bow they may be the sole contact of the bow press during the pressing operation.
    Type: Grant

  • Patent number: 9255760
    Abstract: A dynamic archery bow press with a bow limb securing system, in which each of a pair of slaved pivot arms in a V configuration is provided with a lower gear assembly and an upper drive system that move collectively connected bow limb supports at the upper ends of the pivot arms, the bow limb supports comprising spaced limb contacts set at an acute angle relative to one another along an arc corresponding to a radius of curvature of a flexible portion of the limb of a bow to be pressed, and configured to engage the outer face of a bow limb. In a preferred form, the bow limb supports are generally V-shaped supports with spaced arms including curved limb contact surfaces. The bow limb supports are preferably rotationally adjustable using a spline pin adjustment mechanism that also allows a pair of spaced supports to be mounted on each pivot arm to engage a bow limb or components on a bow.

  • Patent number: 8402955
    Abstract: A bow press for pressing the limbs of compound bows. The press has a pair of coplanar lever arms mounted on a frame. The lever arms are spaced inwardly from their fixed fulcrum points on the frame toward a bow-pressing location defined between their upper ends, such that their path of travel from a starting position is primarily on the downward arcuate path of their range of motion. The starting contact point with the bow's limbs can thus be closer to the bow's cams, reducing the adjustment skill needed to position the bow, and reducing stress on the limbs. In a preferred form, the lever arms are simultaneously operated by a central telescopic screw jack mounted on the frame to reciprocate on an axis perpendicular to the bow held between the lever arms.
