US Patent 5325786: Flechette for a shotgun
US 5325786 · granted 1994-07-05
Abstract
Disclosed is an improved design for individual flechettes, a multiplicity of which are arrayed in an ammunition cartridge for a gun. The flechettes have elongate solid bodies centered about a longitudinal axis, the bodies tapering from a waist to both forward end and rearward end. The waists of the flechettes are closer to the forward end than to the rearward end so that the flechettes' centers of gravity are closer to the forward ends than the rearward ends. The flechettes may have regular polygonal cross sections or essentially regular polygonal cross sections wherein the flechettes define fins along their bodies. Packing arrangements of the flechettes within ammunition cartridges are also shown.

Claim 1
An arrangement of flechettes in a cylinder, comprising: individual flechettes each having a solid elongate body; a front end of the solid body; a rear end of the solid body; a waist on the solid body closer to the front end than the rear end, the solid body tapering from the waist to the ends; a center of gravity in the solid body closer to the front end than the rear end other flechettes each having a generally pyramidally shaped body having an apex and a base; a solid portion of the pyramidally shaped body extending from the apex toward the base; a hollow portion of the pyramidally shaped body between the solid portion and the base; a center of gravity of the pyramidally shaped body closer to the apex than the base said other flechettes interdigitated with the individual flechettes.
