A wire-tethered dart cartridge for electrical discharge weapons wherein the sudden force needed to propel the darts toward a remote target is derived from a source of energy other than expanding gas. The propulsive force is derived from potential energy stored in at least one coiled spring having an arm which impacts the dart with sufficient force to propel the dart a desired distance toward a remote target. In a preferred embodiment disclosed herein, the spring is formed on two interconnected coils, each end of the spring wire extending from a respective coil and forming an impact arm for striking the back of a dart. The arms are maintained in a tensioned configuration by a retention bracket which is connected to a piston pyrotechnic device. When an electrical voltage is applied to the pyrotechnic device, the ignition forces the piston to move the retention bracket to suddenly release the arms. The potential energy in the springs then forces the arms to rotate around their respective coils at high speed and impact the respective darts.

1. In combination with an electrical discharge weapon a dart propulsion apparatus having a pair of wire-tethered darts to be propelled toward a remote target from the electrical discharge weapon; the apparatus comprising:a pair of coiled springs, each having a free end configured as an impact arm for striking a respective one of said wire-tethered darts; a retention device securing said arms in a tensioned state; and a translation device attached to said retention device and responsive to activation of said weapon to translate said retention device away from said impact arms to permit said arms to strike said darts and propel said darts from said weapon.
