Abstract
A non-lethal round of ammunition including an interior non-lethal projectile within an outer casing and a cylindrical foam liner, such as a Styrofoam® liner, surrounding non-lethal projectile. The foam liner is advantageous in that it guides and contains the round and dissipates some of the projectile energy so as not to severely injure the targeted person.
Description
- This application claims priority from provisional application Ser. No. 60/558,010 filed Mar. 30, 2004.
- The present invention relates to munitions in general and specifically to non-lethal ammunition.
- In law enforcement, penal, self-defense and military tactical situations, there is an increasing demand for non-lethal force options. An increasing emphasis has been placed on the use of non-lethal force in stopping or disabling the targeted individual. The use of non-lethal force has the additional advantage of reducing harm to non-targeted bystanders.
- In law enforcement, military and self-defense applications, a number of non-lethal force alternatives are currently in use. These include chemical sprays, such as mace or capsicum sprays which are projected in a stream at a potential attacker, and “stun guns” which disable a targeted individual at close range with electrical current. These devices, although achieving non-lethal force, require that an alternative device be used in place of the ordinary weapon. In addition these options are viable only at close range.
- Another non-lethal force alternative is the use of ammunition which does not impart lethal force. The use of this ammunition has the advantage that it may be used with conventional firearms. The psychological deterrent of the standard firearm is maintained. In addition the range of non-lethal ammunition is sometimes much greater, expanding tactical options.
- One type of non-lethal ammunition uses a dispersable load to produce a less lethal ammunition. U.S. Pat. No. 3,865,038 to Barr discloses a rifle shell comprised of a rubber housing containing a flowable power, liquid, or gas. The body of the housing has thin rupture zones and thicker reinforcement zones to promote rupture of the bullet at selected locations. The nose portion of the bullet lacks the zones of the body and forms a more rigid piston portion of the bullet. Upon impact, the nose of the housing will be elastic yet resist tearing, while the body of the housing will tear and impart force. The thicker nose of the bullet ensures that the nose will not rupture, distributing the force of the bullet. A similar piston device is used for signaling artillery shells disclosed in U.S. Pat. No. 3,983,817 to Tucker. This reference describes an artillery shell having a longitudinal internal chamber which opens to the rear of the shell but is closed to the front of the shell by side walls and the shell nose. Positioned within this chamber is an amount of spotting powder. Upon firing, the spotting powder is accelerated to the nose section of the shell. Upon impact, the powder is ejected by the compressed gas in the shell, allowing the location of the shell to be spotted. U.S. Pat. No. 3,650,213 describes ammunition which fires a hollow projectile from a casing. The hollow projectile is assembled of a body having tail fins added for flight stability and a cap. The hollow projectile may be filled with a dispersable substance. The ammunition has a primer and powder charge positioned behind the hollow projectile. The projectile is propelled by the ignited powder charge. When the projectile strikes an object, the hollow projectile will rupture transferring the contents of the hollow projectile onto the object. The cap has rupture zones to aid in the dispersal of the contents of the projectile.
- In addition to these piston based ammunition, there are also non-lethal projectiles which may be used. For example, U.S. Pat. No. 5,652,407 to Carbone discloses an ammunition round in which a number of cylindrical projectiles are fired from the round. The projectiles fly in various orientations, striking the target at different locations. The projectiles may be used with an associated dye which marks the target for subsequent identification.
- U.S. Pat. No. 6,283,037 to P. J. Sclafani discloses a shot round that features an elastomeric sack, such as a latex sack, filled with a packed particulate load, such as sand, sawdust, soil or grease. The round is constructed with a cylindrical base into which a plastic hull is inserted. The plastic hull extends from the bottom of the base to a closed top end of the hull. Within the round, a wad separates the powder propellent within the base and the chamber above the base encased by the hull. The elastomeric sack is located within this chamber. Additionally the elastomeric sack may contain a dye which would leave a mark on the location of impact. The dye may be separated from the particulate load by a membrane.
- When the round is fired, a primer within the base ignites the powder with the base. The power explosion causes the wad to project the particle packed elastomeric sack from the hull. The elastomeric sack is sufficiently packed to allow for a relatively long distance, i.e. a few hundred yards, with good accuracy. As the elastomeric bag travels it expands slightly. If a dye is included in the elastomeric bag, the different densities of the dye and the packed particle load cause the two elements to mix within the elastomeric bag. Upon impact, the elastomeric bag disintegrates, spreading the force of the impact over an area of the target. As the elastomeric bag ruptures the packed powder disperses. If a dye is included, the target will be marked with the dye. The round provides a cost effective non-lethal projectile alternative which may be used with conventional shotguns.
- Although several different non-lethal projectiles are known, there is still a need for a non-lethal projectile which is simple to manufacture, has adequate range and accuracy, may be made from conventional materials, and may be fired from conventional weapons.
- It is an object of the invention to provide a cost effective shotgun round which may disable a targeted individual without using lethal force. This round should have adequate accuracy, range and stopping power to be used in tactical situations.
- It is an additional object of the invention to provide a round of ammunition which may be manufactured with inexpensive, conventionally available materials.
- It is an additional object of the invention to provide a shotgun round which leaves a mark on the target for subsequent identification, if desired.
- The above objects have been met with a shot round similar to the prior ’037 patent, described above, except that instead of using the outer plastic hull as the container for the elastomeric sack, now a styrofoam cylinder is used as an inner container coaxial with the outer plastic hull, i.e. a cylindrical foam liner is used within an outer cylindrical casing to contain the elastomeric sack with a load or projectile. Dye may be contained in the elastomeric sack with the load, separated from the dye by a membrane. Propellant is separated from the sack by a wad. A cap is used to close the casing and inner liner. Use of foam liners provides energy dissipation as well as trajectory guidance for the elastomeric sack.

FIG. 1 is a cutaway view of a non-lethal round of ammunition including a projectile surrounded by a foam liner. -
FIG. 2 is an exploded view of the non-lethal round ofFIG. 1 . -
FIG. 3 is a perspective view of a barrel of a gun discharging the non-lethal round ofFIG. 1 . - With reference to
FIGS. 1 and 2 , there is seen a non-lethal round ofammunition round 8 comprised of abase 10 and an outercylindrical casing 18, for exampleplastic hull 18, inserted within the base. The top of theplastic casing 18 is shut with, for example acap 13. Inserted into the bottom of thebase 10 is a propellant for propelling the round, including, for example,primer 12.Primer 12 may be electronic, for example, a spark plug-like structure, or chemical, for example a laquer seal. Contained with theouter casing 18 is an innercylindrical foam liner 23, such as a Styrofoam® liner, containing a non-lethal projectile. In one example, the non-lethal projectile is anelastomeric bag 24 including particles having sand or dye (such as the non-lethal round described in the '037 patent described above). Theelastomeric bag 24 is surrounded by thefoam liner 23. An innercylindrical casing 21 may be disposed within theouter casing 18 and thefoam liner 23 may be disposed within the inner cylindrical casing. Thefoam liner 23 guides and contains the non-lethal projectile. - With reference to
FIGS. 1 and 3 , upon firing theshotgun round 8 from theshotgun barrel 25, theprimer 12 ignites thepropellant powder 14 exerting a force on barrier/wad 16 and expelling theelastomeric bag 24 andStyrofoam® liner 23 from thehull 18. Styrofoam is a registered trademark for expanded plastic made of polystyrene. Upon firing, theStyrofoam® liner 23 and non-lethal projectile 24 leave the shotgun barrel. Thefoam liner 23 guides the projectile 24 and dissipates some of the projectile energy so as to prevent the projectile from severely injuring a person. For example, without theStyrofoam® liner 23, the projectile 24 could penetrate the skin of the targeted person. Thefoam liner 23 breaks apart intofoam particles 29, as seen inFIG. 3 , while the projectile 24 hits itstarget 27. Upon impact, theelastomeric bag 24 will deform from an elongate projectile to a wider impact surface, as shown inFIG. 3 . Upon impact, the elastomeric bag may rupture. A high density particle load, such as sand or materials described in the '037 patent may be used.
