Abstract

A cartridge for launching from an electroshock weapon includes a housing adapted for operative connection with the electroshock weapon and having a chamber functioning as a barrel for a projectile unit. The projectile unit includes a conductive head member and an orderly packed wire assembly of electric wire connected with said head member and preferably in coil form. The head member includes a barbed needle for establishing an electrical connection with a target. The electric wire is connected at one end to the head member and at the other end to the housing whereby the wire is withdrawn from the coil as the projectile unit advances toward said target. The project unit is launched by a percussive cap at a rear end of said chamber ignited by the electroshock weapon. At the target an electrical connection is established through the wire to the weapon.

Claims

1. A cartridge for delivering a projectile unit in an electroshock weapon wherein a pair of independent projectile units contact and establish an electrical connection of differing polarity with a target, comprising:

a housing adapted for operative connection with one polarity of the electroshock weapon, said housing having no more than a single chamber forming an opening therethrough wherein said chamber has a cylindrical front section and a coaxial cylindrical rear section;

one of said projectile units located in said chamber, said projectile unit having a head member slidably supported in said front section and a rearwardly extending cylindrical sleeve in said rear section; and

an orderly packed wire assembly of electric wire in said rear section and having one end connected with said head member and another end electrically connected to said housing wherein said wire is arranged in the form of a compact self-supported coil, said head member having contact means for establishing an electrical connection with a target; and

a pyrotechnical energy source carried on said housing at a rear end of said chamber adapted to be ignited by the electroshock weapon for forwardly propelling said projectile unit whereby at said target electrical current of said one polarity is conducted through said wire from the weapon to said contact means for establishing an electrical connection with said target.

2. The cartridge as recited in claim 1 wherein said housing is made of metal or plastic.

3. The cartridge as recited in claim 1 wherein said contact means on said head of said projectile unit has a target-gripping device in the form of a conductive head having at least one barbed needle.

4. The cartridge as recited in claim 1 wherein said wire or said wire assembly is cemented by a bonding agent.

5. The cartridge as recited in claim 4 wherein bonding agent is ductile.

6. The cartridge as recited in claim 1 wherein said projectile unit includes a rear cylindrical sleeve carrying said wire assembly.

7. The cartridge as recited in claim 1 wherein said pyrotechnic charge is triggered by an electrical spark, a fusehead, or by percussive means.

8. The cartridge as recited in claim 1 wherein said projectile unit in retained in said chamber by a cover member over said open end.

9. The cartridge as recited in claim 8 wherein said cover member is an adhesive film.

10. The cartridge as recited in claim 1 wherein said wire is made insulated or non-insulated.
