    Abstract: An aerodynamic element (often referred to as a vane or fletching) that is operatively coupled to the nock end (the back) of an arrow or similar projectile at an angle to the axis of the projectile is known to stabilize flight. This angle, known as offset or helical, in combination with the airflow generates both low and high pressures on different sides of the vane. This pressure difference imparts a torque around the projectiles primary axis which is one component to stabilizing the arrow's flight. Knowing the exact angle of this offset or helical of the vane to the axis of the arrow is critical to create an arrow with optimal performance. The illustrative tool allows the user to very accurately and precisely adjust a fletching jig to exactly the desired angle, as well as being able to setup multiple jigs with exactly the same setup.

    Abstract: An arrow for a bow or crossbow whose point is fitted with a capsule that can be pushed on before shooting. When the arrow is pulled out of a solid object, the capsule remains stuck in the object so that the arrow can be reused again undamaged. A hemispherical shaped flight stabilizer as viewed from the front is mounted on the forward area of a hunting point. During flight, the influence of side winds on the arrow is eliminated and thus an accurate shot is always made possible. The flight stabilizer consists of a material that can be easily destroyed when it strikes the target and is preferably in the form of a sphere that can have indentations on its surface. The shaft of a crossbow dr bow is fitted with members easily reached by the shooter, so that the point of is the arrow can be inserted exactly into the center of the spherical flight stabilizer.

    Abstract translation: 箭头或弩的箭头，其点配有可以在拍摄之前被推开的胶囊。 当将箭头从固体物体拉出时，胶囊保持卡在物体中，使得箭头可以再次被再次使用而不被损坏。 从前方观察的半球形飞行稳定器安装在寻点的前部区域。 在飞行过程中，侧风对箭头的影响被消除，从而始终使准确的射击成为可能。 飞行稳定器由当其撞击目标时容易被破坏的材料组成，并且优选地是能够在其表面上具有凹陷的球体的形式。 弩弓弓的轴装配有由射手容易到达的构件，使得箭头的点可以准确地插入球形飞行稳定器的中心。

    Abstract: An archery arrow testing apparatus which comprises a pair of upright arrow support stands. The apparatus further includes a pair of wooden or plastic pedestals. The stands each have a pair of spaced apart thin flat upright legs. Vertically extending slots are provided in the wooden pedestals. The slots are sized to receive and support the thin flat upright legs when the legs are engaged in the slots. An adjustably mountable rod is mounted in horizontally extending holes in the pedestals with opposite ends of the rod engaged in the holes connecting the pedestals together in a supported upright position. Archery arrow testing means is provided which comprises sets of revolving thin metal discs. Means is further provided for mounting a series of the discs in pairs on each of the pedestals with the discs being rotatable relative to the pedestals enabling an archery arrow to be spun in circumferential orbit on the discs for a human eye to scrutinize to ascertain trueness of an orbiting archery arrow.

    Abstract: Arrow fletchings (42,102) disclosed have curved vanes (50,114) inclined inwardly in a rearward direction to provide pockets (54,118) for restricting air flow while allowing vane flexing in a manner that moderates drag in response to wind changes. One fletching embodiment (42) is preferably made by plastic extrusion and a subsequent heat forming process and includes a vane (50) whose inner portion projects radially from its foot (44) and whose outer portion define its curved pocket (54). Another fletching embodiment (102) made from sheet plastic includes a vane (114) that projects tangentially from the arrow shaft on which its foot (104) is mounted and is curved to define the pocket (118) that restricts air flow. A fixture (68) for heat forming the pocket of the one fletching embodiment (42) and a method for making the other fletching embodiment (102) are also disclosed.
