Abstract
A non-lethal spread projectile has a center pin (1) as a guide on which a weight plunger (5) is caused by impact stop of gun-fired flight momentum to slide from an aft end (3) to a front end (2) of a spread projectile (4) for spreading fill material (9) in a fill bag (10) ahead of the weight plunger over a broad surface of an impacted target (25) for preventing damaging penetration of the spread projectile into the impacted target and to mark the impacted object predeterminedly.
Claims20
A non-lethal-spread projectile comprising:
- a center pin (1) extended from proximate a front end (2) to proximate an aft end (3) of a spread projectile (4);
- a weight plunger (5) having a central orifice with plunger walls (15) slidable on an outside periphery of the center pin (1) and having a plunger circumferential perimeter (7) proximate a stabilization-fin-height distance inward from a projectile circumferential perimeter (8) of the spread projectile (4);
- the weight plunger (5) having a mass predetermined for causing the weight plunger (5) to travel forward on the center pin (1) from momentum force of projectile travel when the projectile travel is stopped from impact of the spread projectile (4) with an impacted object (25);
- predetermined fill material in a fill bag (10) intermediate a grooved head (11) and proximate the weight plunger (5);
- the center pin (1) having a pin front (12) attached to the fill bag (10);
- at least one flight-stabilization fin (13) on the spread projectile (4);
- and
- the fill bag (10) having a volumetric capacity for containing a predetermined volume of the fill material and for positioning of the fill material over a predetermined area of an impacted object (25).

A method comprising the following steps for spreading a spread projectile (4) on an object with impact momentum:
- providing a weight plunger (5) on an aft end (3) of the spread projectile (4);
- positioning a flight-stabilization fin (13) on the aft end (3) of the spread projectile (4);
- providing fill material in a fill bag (10) intermediate the weight plunger (5) and a head of the spread projectile (4);
- positioning the weight plunger (5) in slidable contact with a linear guide member intermediate the aft end (2) of the spread projectile (4) and a front section (3) of the spread projectile (4);
- and
- causing the weight plunger (5) to have a mass predetermined for gun-fired flight momentum of the weight plunger (5) to push the weight plunger (5) against the fill bag (10) for causing the fill material in the fill bag (10) to spread over an impacted object (25) intermediate the impacted object (25) and the weight plunger (5) predeterminedly.
