Abstract
A versatile, dearmer using small arms cartridges that is low cost, may be usable, and can employ various types of destructive projectiles including water, clay, shot and steel slugs. A novel feature is a shock tube firing circuit which, when combined in a multiple barrel embodiment, produces multiple projectiles with a high degree of firing simultaniety.
Claims19
A versatile dearmer using small arms cartridges comprising:
- a barrel having a receiver sized to receive a small arms cartridge and a muzzle end;
- and
- a housing to stabilize and hold said barrel in stable firing position;
- and
- a mechanical firing circuit comprised of a piston shaped on one end as a firing pin slidably mounted in a tubular guide operatively positioned to fire a small arms cartridge loaded in the receiving end of said barrel;
- and
- an unspecified length of shock tube to initiate movement of the piston in said mechanical firing circuit;
- and
- an initiator to initiate energy transfer in said unspecified length of shock tube.

A versatile dearmer using small arms cartridges comprising:
- a plurality of barrels having receiver ends operatively sized to receive a particular caliber or gauge of small arms cartridge and firing ends;
- and
- a housing for each of said barrels to stabilize and hold the firing ends of said barrels in firing position toward an improvised explosive device to be dearmer, and
- a shock tube initiated firing circuit operatively mounted in firing proximity to the receiver ends of each of said barrels;
- and
- a shock tube connector capable of connecting said plurality of barrels to a single section of shock tube;
- and
- a shock tube initiator to initiate energy transfer in said single section of shock tube.

A versatile dearmer comprising:
- a rectangular wooden housing having a breach and receiving end, each containing a barrel support hole in axial alignment with the opposing hole;
- and
- a barrel operatively sized to receive a 12-gauge shotgun shell having a breach end and a firing muzzle end operatively mounted within said wooded housing;
- and
- a shotgun shell disposed within the breach end of said barrel;
- and
- a breech cap containing a center hole threadably attached to the breech end of said barrel to urgingly retain the 12-gauge shotgun shell in firing position within said barrel;
- and
- a shock tube initiated mechanically operated firing device threadably attached to the hole in said breech cap;
- and
- a length of shock tube having an initiation end, and a firing end attached to said firing device;
- and
- a shock tube initiator attached to the initiator end of said shock tube to initiate energy transfer in said length of shock tube.
