Abstract: A hoof block is provided that joins with a livestock hoof via an adhesive. The block can include a body bounded by an interior edge and a curvilinear exterior edge approximating an outer edge of the hoof and multiple shearing polygonal apertures extending through the body. Each of the shearing apertures can have a pointed end and can lay along a reference line that can be disposed at an angle, for example, 30-60 degrees inclusive relative to the interior edge. The apertures can be joined with bridges that shear through the body when the hoof block becomes removed from the hoof and encounters a pump impeller in a livestock facility. The block can break into pieces that do not substantially impair continued operation of the pump impeller, and yet can support the standing and walking loads of the livestock while on the hoof. A related method of use is provided.

Abstract: A fletching jig can include constrictor ring that, when rotated, urges a plurality of arms supporting respective vanes toward an arrow supported in the jig to fletch the arrow. The arms can extend away from a base, which can support the arrow along a central axis. The actuator ring can be disposed around the arms. The actuator ring can include a ramp that can engage multiple guide blocks adjacent the actuator ring, each guide block configured to push a respective arm toward the arrow as the ring rotates. A related method of use is provided.

Abstract: An elongated gap filler is provided including a first panel and a second panel in a V configuration joined at an apex, a first extension wall extending from the first panel, a first sealer wall extending downward and transversely to the first extension wall, and a second extension wall extending from the second panel. The first sealer wall can seal against a surface of a wall and set a depth of insertion of the first and second panels and first extension wall into a gap between building surfaces, e.g., a wall top and a ceiling or roof. The second extension wall can be arcuate and can bend against the ceiling or roof. The first sealer wall can be arcuate and can bend against a vertical wall surface. The apex can include a U-shaped groove to enhance articulation of the panels. A related method of use also is provided.

Abstract: A vane, for a projectile such as an archery arrow, including a ribbon strip having a leading ribbon edge that is twisted to induce spin of the projectile during its flight. The vane can include a base that mounts to a projectile surface. The ribbon strip can extend upward from the base and can be semi-rigid but flexible. The ribbon strip can include an intermediate portion spaced a distance from and free from attachment to the projectile surface so as to form a gap under the intermediate portion. The ribbon strip can include a second ribbon end that is attached to the base rearward of the first end. It also can include a fin that extends upward from the base within a gap between the ribbon strip and base. The ribbon strip alternatively can include a cantilevered second ribbon end that is free from attachment to the base and projectile.

Abstract: An arrow fletching device suitable for mounting Mylar fletching vanes to the surface of an arrow. The device includes a clamp for holding the fletching in a manner that leaves a surface mounting portion of the side of the fletching exposed. Then an adhesive is applied to the exposed surface and the clamp is pressed up against the arrow to securely mount the fletching to the arrow surface. One version utilize three such clamps posited at 120 degree offsets to mount three vanes around the surface of the arrow.

Abstract: A nock or an arrow with a nock suitable for being launched with a slingshot or slingbow. The nock includes a shank that is of sufficient length to fit within the pocket of a slingbow without interfering with the fletching. The nock also includes a flared element to facilitate gripping of the nock. The nock can include a connection shaft for attachment to the shaft of an arrow.

Abstract: A bowfishing reel system that can use a standard reel or a normally biased open reel each having a lever that when actuated forces the bail into the open state. A mechanical coupling, such as a string is connected between the lever of the reel and the bow cable or bow string. When the bow is drawn, the mechanical couple causes the lever to be actuated and thus forcing the reel into the open state. As such, when a user goes to shoot an arrow at a target, as soon as the bow is drawn the bail is opened thus preventing back lash and injury.

Abstract: A bowfishing reel that is biased into an open position in which the line is free to be fed from the reel. When desired, the user can actuate a mechanism that forces the bail into the closed position while the mechanism is engaged. Once the mechanism is released, the bail returns to the open position.

Abstract: A bowfishing arrow with a medium that receives a slider and allows the slider to traverse a substantial length of the arrow shaft. The slider can receive a fishing line and when being drawn, the slider allows the slider and fishing line to remain in front of the bow and, upon release, the slider traverses to the back of the arrow during flight but, the slider at all times remains in front of the bow.

Abstract: A crossbow, or an assembly for a crossbow, that allows the crossbow to be broken down for storage or transport, and then easily assembled together again for operational use. A riser may be attached to the barrel of the crossbow and that can receive the limbs. The riser is attached using pins or securing devices that can be easily removed to allow the riser to be removed from the barrel. By removing all but a foremost securing device, the riser can be rotated to a storage position. One of the securing devices may be used to attach a stirrup to the riser in a hinge-like fashion, wherein the stirrup can be rotated to one of several positions.
