Description

FIELD OF THE INVENTION

The present invention generally relates to projectiles, particularly shotshell pellets, for use in a shotgun.

BACKGROUND OF THE INVENTION

Exemplary embodiments disclosed herein relate to shotshell pellets (also referred to as “shot”) for a shotgun ammunition system (“cartridges” or “shotshells”). Shotshells are typically filled with shotshell pellet of a uniform size, classified according to the nominal diameter of the pellet along with the material (e.g., lead, steel, non-toxic alloys, and the like) and the intended target. Standard sizes have developed for different intended targets, for example ranging from 000 buckshot (0.36 inch (in.) diameter) to 5 (0.12 in. dia.) or 6 (0.11 in. dia.) to 9 (0.08 in. dia.) and smaller shots. Typically, a plurality of such shotshell pellets are loaded in a shotshell comprising a casing defining an internal chamber that also includes propellant and a primer.

DETAILED DESCRIPTION

FIGS. 1-2 show a projectile 20 constructed in accordance with embodiments of the invention. In some embodiments, the projectile 20 comprises a top pole 22 and a bottom pole 24 that are generally or substantially flat disc-like sections. The top pole 22 and the bottom pole 24 are substantially equidistant from a vertical center 26 and that define a vertical axis 28 through the top and bottom poles 22, 24. In other embodiments, the projectile 20 also includes a body 30 defining an exterior surface 32 and having a ring 34, one or more upper sections 40, and one or more lower sections 60. The ring 34 protrudes from an equator 36 about which the body 30 may be substantially symmetric, i.e., divided into upper and lower hemispheres. The ring 34 also defines a vertical ring height 38.

The one or more upper sections 40 extend between the equator 36 and the top pole 22. In certain embodiments, a plurality of upper sections 40 are provided that, when viewed in cross-section (FIGS. 3A and 3B), are defined by first and second walls 42, 44 that are substantially flat and are disposed at different angles relative to the vertical axis 28. Any number of walls is contemplated, including embodiments with one, two, three, four, or more walls defining the one or more upper sections 40. The body 30 of the projectile 20 defines a plurality of corners between sections, the plurality of corners being angular and including a first corner 46 between the top pole 22 and the first wall 42, a second corner 48 between the first wall 42 and the second wall 44, and a third corner 50 between the second wall 44 and the ring 34. Each of the one or more upper sections 40 defines a substantially frustoconical shape. In certain embodiments shown in FIG. 4, each of the first corner 46, second corner 48, and third corner 50 defines a substantially circular shape about the vertical axis 28. In a general sense, the plurality of upper sections 40 and the plurality of lower sections 60 constitute sides forming interrupted surfaces between the ring 34 and the respective the top pole 22 and bottom pole 24. The body 30 is interrupted in the upper sections 40 by the first wall 42 and the second wall 44 extending at different angles relative to the vertical axis 28, forming angular steps that define the first corner 46, second corner 48, and third corner 50. Likewise the body 30 is interrupted in the lower sections 60 by the first wall 62 and the second wall 64 extending at different angles relative to the vertical axis 28, forming angular steps that define the first corner 66, second corner 58, and third corner 70.

The one or more lower sections 60 extend between the equator 36 and the bottom pole 24. In some embodiments, a plurality of lower sections 60 are provided that, when viewed in cross-section (FIGS. 3A and 3B), are defined by first and second walls 62, 64 that are substantially flat and are disposed at different angles relative to the vertical axis 28. Any number of walls is contemplated, including embodiments with one, two, three, four, or more walls defining the one or more lower sections 60. The body 30 of the projectile defines a plurality of corners or inflection points between walls and poles, including a first corner 66 between the bottom pole 24 and the first wall 62, a second corner 68 between the first wall 62 and the second wall 64, and a third corner 70 between the second wall 64 and the ring 34. In certain embodiments similar to the upper section 40 shown in FIG. 4, each of the first corner 66, second corner 68, and third corner 70 defines a substantially circular shape about the vertical axis 28.

FIGS. 3A and 3B illustrate how embodiments of the present disclosure provide a multi-faceted shot that is not spherical. The projectile 20 has several stepped surfaces including the frustoconical walls 42, 44, 62, 64, such surfaces together providing angular steps between the ring 34 and the poles 22, 24. Likewise the top and bottom poles 22, 24 are flat sections. The embodiment of FIGS. 1-4 provides a multi-faceted exterior surface 32 and does not include any three-dimensionally curved surfaces that could define a portion of a sphere, let alone any such curved surfaces across a majority of the exterior surface 32 of the projectile 20.

FIG. 3A shows particular dimensions for the projectile 20 applicable to embodiments of the present disclosure. The illustrated projectile 20 is in the class of a #5 birdshot (0.12 in. diameter). It will be appreciated that various other sizes are contemplated while maintaining similar relative dimensions of the constituent parts of the projectile 20. These dimensions include the ring height 38, a vertical diameter 80, a second corner height 82, a horizontal diameter 84 for the ring 34 at the equator 36, a pole diameter 86 (also considered a first circle diameter 86), a second circle diameter 88, and a third circle diameter 90. The ring 34 also defines a ring angle 92 measured between an upper wall 94 and a lower wall 96 of the ring 34. The ring angle may be about 83 degrees, about 80-90 degrees, or about 75-95 degrees.

In the embodiment of FIG. 3A, the vertical diameter 80 and third circle diameter 90 are 101% and 102%, respectively, of the standard 0.12 in. diameter for a #5 shot. Although the projectile 20 is not spherical, these dimensions define the closest analogue in standard spherical shots, allowing for similar uses (e.g., hunting similar game as with the corresponding standard). In embodiments, the horizontal diameter 84 is appreciably larger and constitutes 130% of the standard diameter, which produces the ring 34, that projects out from the more “standard” dimension of a #5 shot (or another size shot). In other words, the ring 34 projects out substantially further than the dimensions 80, 90 that more closely correspond to a standard sized shot. More generally, embodiments applicable to the present disclosure may have vertical and third circle diameters 80, 90 within about 95%-105% of the standard diameter of a given shot size, or within about 90%-110% of such standard diameter. Table 1 below provides a partial list of standard shot dimensions applicable to the present invention. It will be appreciated that the sizes noted below are representative standards; however, other organizations or individual manufacturers may use different sizes. The present invention is applicable to any such size even if not explicitly listed in Table 1.

The other dimensions shown in FIG. 3A may be derived and implemented as a function of the vertical diameter 80 and/or the third circle diameter 90. Notably, in embodiments the vertical ring height 38 measured relative to either the vertical diameter 80 or the third circle diameter 90 may be more than 20%, 26-50%, 30-40%, about 29-31%, or about 33-36%. As such, Table 1 below shows dimensions expressed as a function of another determined dimension. Additionally, the last column in Table 2 lists measured dimensions for manufactured prototypes of the #5 shot of FIG. 3A.

The variability in dimensions shown above in the last column of Table 1 is due to various manufacturing tolerances, tooling precision, material variability (e.g. degree of compaction of powdered material before pressing), and the like. Accordingly, in these manufactured embodiments the ratio of the vertical ring height 38 to the vertical diameter 80 ranges from 35-36% and the ratio of the vertical ring height 38 to the horizontal diameter 84 ranges from 33-35%. Additionally, the ring angle 92 in these manufactured embodiments can range from about 85-93 degrees.

FIG. 3B shows particular dimensions for the projectile 20 applicable to certain embodiments of the present disclosure in the class of a #6 birdshot (0.11 in. diameter). It will be appreciated that the relative dimensions in this embodiment correspond to the ranges of values in Table 1 above. For example, the illustrated vertical diameter 80 and third circle diameter 90 are 94% and 95%, respectively, of the standard 0.11 in. diameter for a #6 shot.

In certain embodiments, shot as described above can be formed from various selected materials including lead, steel, tungsten, alloys thereof, green materials, or the like.

In certain embodiments, shot 20 as described herein can be made from powder components and be formed using a powder press. The powder press comprises a lower hemispherical cavity, an upper hemispherical cavity and a plate in between the two cavities comprising a central ring-shaped opening. The ring-shaped opening may be cylindrical or may have other desired shapes to form the equatorial ring 34 on the projectile 20 having a shape described above. Powder components placed in the cavities within the ring may be combined with lubricants and/or binders and are pressed to the desired shape.

In embodiments, the shot 20 described above may be sintered. For a sintered shot, the equatorial ring 34 may be made larger for ease of manufacture. For example, for a 3 to 5 mm diameter high density shot, the ring height 38 may be between about 40-45% of the vertical height 80. For a 5 mm sintered shot, the band can be made between about 2.0 mm and 2.25 mm in its width. For a sintered shot larger than about 5 mm, the ring height 38 in some embodiments can be reduced to about 25-30% of the vertical height 80.

In other embodiments, shot as disclosed may be manufactured using a ball header process. Ball header machines are particularly suitable for forming steel shot. For example, a steel wire may be fed into the header, the wire having a diameter smaller than the desired diameter of the final shot. The header will cut the wire, and two heading cavities will be pressed toward the ends of the wire. By adjusting the pressure applied by the header, shot having the shapes described above may be formed, particularly with the desired shape and size of the ring 34. The ring 34 is desirably formed between the two heading cavities beyond the edges of the two cavities.

Embodiments of the shot described above advantageously improve the manufacturing, aerodynamics, ballistics, and terminal performance of the shot. The disclosed embodiments are readily adaptable to high-volume and low-cost manufacturing processes, such as those discussed above. For an example of ballistic improvement, in a method of using the shot, a user may fire a shotgun shell including the shots (projectiles) as described above. When the shot impacts the desired target, the equatorial ring 34 and/or the corners 46, 48, 50, 66, 68, 70 provide cutting surfaces for increased penetration. Aerodynamically, the ring 34 and overall shape may affect the trajectory of the shots, which can desirably improve the spray size and/or consistency, velocity, and/or distance of the shot traveling to the target.

In certain embodiments shown in FIG. 5, a projectile 520 includes top pole 522 and a bottom pole (not shown) that are arranged with a depressed circular surface 523 inside an outer ring 525. The outer ring may be a flat frustoconical surface, a concave surface, or a convex surface. The depressed circular surface 523 may be substantially flat, convex, or concave.

FIGS. 6-9 show a variety of alternative embodiments applicable to the present disclosure. One or more of the illustrated features may be applicable to any other disclosed embodiment in part or in whole, including the embodiments of FIGS. 1-3 and 5. It will be appreciated that these features may affect certain dimensions listed in Table 2 without significantly affecting the ring height 38, vertical height 80, second corner height 82, first circle diameter 86, and the horizontal diameter 84. FIG. 6 shows an embodiment of a projectile 620 comprising a top pole 602 and a single upper section 640 extending to a ring 634. A ring 635 has an angular waist 635 at an equator 636. In other embodiments, a lower section 660 has a plurality of dimples 661 for improving aerodynamics.

FIG. 7 shows an embodiment of a projectile 720 comprising poles and walls that are curved concave or convex, such as a concave top pole 702 and a concave wall 764 of a plurality of lower sections 760. The shot may include a convex bottom pole 704 or a convex wall 744 of a plurality of upper sections 740. A ring 734 may likewise have a convex portion 735 or a concave portion 737 formed therein. These various curved surfaces may be defined by different radii of curvature or substantially equal radii of curvature. Likewise it will be appreciate that curved inflection points may be provided between the poles and walls or between the walls and ring may be provided in lieu of the corners shown in other embodiments.

FIG. 8 shows an embodiment of a projectile 820 with a ring 834 defined by a substantially vertical wall 835 extending between a plurality of upper sections 840 and a plurality of lower sections 860, resulting in a substantially 12-sided cross-sectional form.

FIG. 9 shows an embodiment of a projectile 920 comprising a ring 934 formed of substantially flat walls 935, 937, and 939.

FIG. 10 shows an embodiment of a projectile 1020 comprising a ring 1034 that is substantially similar to the ring 34 of FIGS. 1-4. In this embodiment, a substantially spherical upper hemisphere 1021 and a substantially spherical lower hemisphere 1023 extend from the ring 1034, providing a rounded shape without the corners or substantially flat walls and poles of other embodiments.

FIG. 11 shows an embodiment of a projectile 1120 shown in an exploded view that is similar to the projectile 20 of FIGS. 1-4. However, in this embodiment, the illustrated brackets indicate areas of selectably variable or indeterminate length formed of the same material as the rest of the projectile and otherwise having substantially the same profile. In this manner, the projectile may be longer or shorter in horizontal and/or vertical directions as indicated by the brackets. Such variations in length may result in the projectile 1120 being oblong in either the vertical or horizontal direction.
