  • Patent number: 7185644
    Abstract: A bow press for use in stringing bows includes a base member and left and right inclined spacer bars adjustably positionable along the base member, each spacer bar supporting a bow limb roller thereon. An upper end portion of one spacer bar mounts a bow limb roller, a pivot connector mounts the upper end portion to the spacer bar for pivotal movement of the upper end portion toward and away from the other spacer bar and a hydraulically operated piston or turnbuckle causes the upper end portion to pivot about the pivot connector toward the other spacer bar, whereby a bow limb of the bow is caused to bend toward the other bow limb to release the tension in the bowstring.

  • Patent number: 6932070
    Abstract: A bow press for use in stringing or repairing bows includes a base member, a vertical riser bar pivotally supporting a horizontal riser beam on which are adjustably mounted two handle rollers, left and right inclined spacer bars adjustably positionable along the base member, each spacer bar supporting a limb roller thereon and a jack mechanism for moving the riser bar up and down. An upper end portion of one spacer bar mounts a limb roller, a pivot connector mounts the upper end portion to the spacer bar for pivotal movement of the upper end portion toward and away from the other spacer bar and a hydraulically operated piston causes the upper end portion to pivot about the pivot connector toward the other spacer bar, whereby a bow limb supported by the limb roller is caused to bend toward the other bow limb to release the tension in the bowstring.

  • Patent number: 6386190
    Abstract: A bow press for use in stringing or repairing bows, including compound bows, has a riser operated by a winch mechanism. The bow press includes a riser bar for supporting an inclined riser beam having spaced apertures for positioning two handle rollers thereon. Left and right inclined spacer bars each support a limb roller thereon. Each of the handle rollers and limb rollers includes an axle, and two spaced portions defining an inclined groove therebetween. The inclined groove receives a portion of a bow to support the bow during stringing or re-stringing operations. The riser bar is adjustably movable upwards and downwards by operation of a winch. The base member adjustably supports left and right spacer bars. The left and right spacer bars are adjusted along the base member, and secured in position by respective tensioning members. The base member is a table or other support surface. Alternately, the base member is attached to upstanding leg members, which support the bow press upon the floor.
