Abstract

A cartridge for propelling a pair of wire-tethered contact darts for disabling a remote target with an electrical discharge. The cartridge comprises two bores each having one wire-tethered dart in front of an electrically activated pyrotechnic. A cartridge contains two separated straight bores, which each launch a single dart assemblage with a single primer of standard manufacture. A single 200 large rifle primer can launch a single dart assemblage reasonably accurately to 30 feet from the cartridge. Each assemblage is deflected to a predicted angle of flight when it collides with a center hinged cover as it exits the cartridge. This arrangement allows for longer flight distances and tighter, but still effective, dart spreads throughout the travel.

Claims (6)

1. A cartridge for use in a stun gun, the cartridge having a pair of wire-tethered contact darts adjacent respective electrically activated pyrotechnics for propelling the darts toward a remote target for disabling the target; the cartridge comprising:

a pair of elongated bores that are space apart from one another,

one of said contact darts positioned in each of said bores,

said elongated bores being substantially; parallel to one another; and

a hinged cover affixed to an exterior surface of said cartridge between said bores, unaffixed portions of said cover extending over said bores for being deflected therefrom by said contact darts upon their exiting from said bores.

2. The cartridge as recited in claim 1 wherein said exiting darts are deflected apart by said unaffixed portions of said cover.
