The launcher may have internal rifling grooves within the barrel to effect rotation of the projectile and radial expansion thereof due to centrifugal force.

11 Claims, 6 Drawing Figures HIGH ENERGY MINIMUM LETHALITY WEAPON SYSTEM BACKGROUND OF THE INVENTION Weapons presently employed in law enforcement work have several disadvantages. The primary drawback of conventional arms is the possibility of inflicting mortal injury to an alleged suspect. Another drawback is that an innocent bystander may be injured. Another is that a lethal weapon may also be a threat to the police officer if the weapon is recovered by a suspect during an altercation. A third disadvantage is the requirement that all weapons inflict minimal injury to a suspect imposed by our legal system which reserves to the courts the responsibility for determining guilt and sentence of suspected offenders.
The basic requirement of a weapons system for most law enforcement work is the ability to incapacitate as opposed to inflict injury. The requirement for incapacitation is imposed in order to prevent suspect targets from fleeing, engaging in further combat, or committing other acts an officer properly wishes to stop.
No heretofore known weapon fulfills all of the above requirements. For example, usefulness of the billy club or the baton is limited by the reach of the individual employing the device. The desirable quality of a billy club is that it has the capability of delivering an incapacitating blow without penetrating the body of the offender. If this concept is extrapolated then, that what is needed is a long-range device that inflicts a blow as that of a billy club or incapacitates in some other manner.
SUMMARY OF THE INVENTION This invention relates generally to minimum lethality weaponry area, but more particularly to a deformable projectile adapted to be fired by an appropriate launcher. The projectile radially expands during its trajectory by centrifugal force thereby delivering an impact of relatively high total energy but of relatively low unit area energy so as to incapacitate while minimizing body penetration.
It is the primary object then of this invention to provide a minimum lethality projectile capable of incapacitating a human target without body penetration or imparting mortal injury.
It is a further object of this invention to provide a projectile having an initial relatively small cross-sectional area adaptable for reception into a launcher and that is radially expandable while in trajectory so that the launching device does not have to be unduly large and unwieldy.
Another object of this invention is to provide a minimum lethality projectile having the ability to conform to the shape of a target thereby allowing a uniform energy distribution over a relatively large area ofthe target.
Other objects and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a prospective view of the cartridge with a quarter section broken away to disclose the interior construction;
FIG. 2 is a partial elevation of an appropriate launcher with one half of the barrel portion broken away to show the orientation of the cartridge;
FIG. 3 is the same partial elevation as in FIG. 2 wherein the projectile is shown immediately after fir- FIG. 4 is again the same partial elevation indicating the relative positions of the various elements after exit of the launcher barrel;
FIG. 5 is a further elevation of a fully radially expanded minimum lethality projectile in trajectory toward its target; and
FIG. 6 is a second embodiment of the minimum lethality projectile in the form of an incapacitating net fully radially expanded and in trajectory moving towards a target.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Turning now to the drawings, FIG. 1 indicates a cartridge' 10 comprising a case 12 closed on one end by an end seal M, and on the opposite end by a primer case 16. The primer case 16 has a radially extending flange 18 for positioning purposes. The primer case 16 is provided with a counterbored aperture 20 for the acceptance ofa primer 22.
A spacer 24 has a further enlarged longitudinal counterbore portion 26 for the acceptance of a charge 28. The purpose of the spacer 24 is to provide volume control of the charge cavity and thereby control the kinetic energy imparted to a projectile.
A piston 30 adapted to circumferentially engage the inner periphery of the cartridge case 12, communicates with the inward face of spacer 24. Its opposing face is in contact with a gas check 32. In the embodiment indicated in FIG. 1, the piston 30 is constructed of polyethylene and the gas check 32 of felt but comparable materials could be substituted without detracting from the effectiveness of the cartridge 10.
Disposed between the gas check. 32 and the end seal 14 is a non-lethal projectile 34 adapted to snugly conform to the geometric volume between said end seal member 14, said gas check 32, and the inner periphery of said cartridge case 12.
FIG. 2 illustrates an exemplary launcher 36 having a barrel 38 with internal rifling, for example a United States Military 40MM Grenade Launcher (M79 or XM-l48) wherein the cartridge 10* is indicated in firing position in the receiver portion of said launcher 36. It will be appreciated that the firing pin of launcher 36 is on the centerline of the primer 22. Firing is accomplished by a rearward pull of trigger 40 causing the firing pin to strike the primer 22 in a manner well known in the art thereby detonating the charge 28. The cartridge casing 12 is restrained by the radially extending flange 18 thereof communicating with an opposing surface within the receiver portion of the launcher 36 as is common in the art. The detonation force of the charge drives piston 30 toward the muzzle end of barrel 38 driving with it the projectile 34, and end seal member 14. Due to the internal rifling within barrel 38, it will be appreciated that rotation is imparted to the projectile 34 as well as longitudinal thrust.
FIG. 4-indicates the relation of the elements of the cartridge 10 upon exit from the barrel 38 of the launcher 10. The end seal 14, and. piston 30 have appreciably less mass than the projectile 34 and therefore separate from the trajectory of the projectile 34. Due to rotation accomplished by the rifling of the launcher, centrifugal force causes the projectile 34 to expand radially thereby assuming a somewhat pancake shape.
FIG. 5 indicates the projectile 34 in its fullest radially expanded form proceeding in its trajectory in a manner calculated to provide a minimum lethality but incapacitating impact to its target.
In the preferred embodiment of the invention, the projectile 34 is constructed of a heavy woven fabric loaded with steel shot and resembling a bean bag. A projectile adapted to be fired by a cartridge designed for the U. S. Military 4OMM Grenade Launcher M79 will weigh approximately one half pound.
FIG. 6 disclosed another embodiment of the projectile 34 comprising a net that radially expands to assume a shape many times its compacted diameter. The net 34 has weights 36 secured to its periphery to enhance rotation due to centrifugal force and to stabilize its trajectory. This embodiment of the projectile is calculated to encircle or wrap around a target thereby to incapacitate the target.
While it will be apparent that the embodiments illustrated herein are calculated to fulfill the objects above stated, it will be appreciated that the present invention is susceptible to modification, variation and change without departing from the scope of the invention.
