Abstract

Abstract The invention is an improved chemical firearm device that is operated and fired by an electro-mechanical system. The firearm device is of a pistol configuration, having a tank-like handle or hand-grip for containing the chemical to be discharged. A dual-action mechanical trigger mechanism is provided for first discharging the chemical through a nozzle in the barrel portion of the pistol-like device, which can be aimed like a pistol toward an assailant or target, and second to ignite the chemical during discharge if desired. An optional action is available whereby the ignition of the already discharged chemical on the assailant, or on the target, may be delayed until desired or needed in a point of close combat with the assailant or at the target. Another optional action is the availability of a high-voltage charge to stun and disable an assailant during close combat without the use of the chemical. Other uses include destruction of pest nests, and similar situations.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 245 words
An electro-mechanical chemical firearm device, comprising: a hollow handle means, said hollow handle means being fully enclosed and capable of containing a fuel under pressure, and a fuel in said hollow handle means under pressure; a hollow barrel means, said hollow barrel means being surmounted on and attached to one end of said hollow handle means, said hollow barrel means having an open muzzle end; a fuel piping system, said fuel piping system being within said hollow handle means and said hollow barrel means, said fuel piping system connecting the interior of said hollow handle means to said open muzzle end of said hollow barrel means and communicating therewith, said fuel piping system transporting said fuel from said hollow handle means to said open muzzle end of said hollow barrel means; an electrical power system within said hollow handle means and said hollow barrel means, said electrical power system being capable of producing a high-voltage spark at said open muzzle end of said hollow barrel means, said high-voltage spark being capable of igniting fuel from said fuel piping system; a dual trigger mechanism consisting of a first trigger member to release said fuel under pressure in said hollow handle, and a second trigger member to activate said electrical power system to produce said high-voltage spark, said first and second trigger members being capable of concurrent operation and of independent operation, said first trigger member being capable of lateral movement to clear said second trigger member.
Claim 2
Dependent Claim 245 words
An electro-mechanical chemical firearm device, comprising: a hollow handle means, said hollow handle means being fully enclosed and capable of containing a fuel under pressure, and a fuel in said hollow handle means under pressure; a hollow barrel means, said hollow barrel means being surmounted on and attached to one end of said hollow handle means, said hollow barrel means having an open muzzle end; a fuel piping system, said fuel piping system being within said hollow handle means and said hollow barrel means, said fuel piping system connecting the interior of said hollow handle means to said open muzzle end of said hollow barrel means and communicating therewith, said fuel piping system transporting said fuel from said hollow handle means to said open muzzle end of said hollow barrel means; an electrical power system within said hollow handle means and said hollow barrel means, said electrical power system being capable of producing a high-voltage spark at said open muzzle end of said hollow barrel means, said high-voltage spark being capable of igniting fuel from said fuel piping system; a dual trigger mechanism consisting of a first trigger member to release said fuel under pressure in said hollow handle, and a second trigger member to activate said electrical power system to produce said high-voltage spark, said first and second trigger members being capable of concurrent operation and of independent operation, said first trigger member being capable of lateral movement to clear said second trigger member.
Claim 3
Dependent Claim 40 words
The electroc-mechanical chemical firearm device as recited in claim 1, wherein said hollow handle means has a check-valve inlet therein for injecting fuel into the interior of said hollow handle means, said hollow handle means serving as a fuel tank.
Claim 4
Dependent Claim 127 words
The electro-mechanical chemical firearm device as recited in claim 2, wherein said fuel piping system consists of: a fuel line, said fuel line having an inlet means at the lower most point of said fuel line in said fuel tank, said fuel line then extending into said hollow barrel means and thence to said open muzzle end thereof, a nozzle at said open muzzle end, said fuel line terminating in said nozzle at said open muzzle end; a valve in said fuel line, said valve being within said fuel tank, said valve extending through a face of said hollow handle means to connect to said first trigger member for operating said valve, said valve being spring loaded to return to closed position when said trigger is released.
Claim 5
Dependent Claim 90 words
The electro-mechanical chemical firearm device as recited in claim 3, wherein said electrical power system is battery powered, said electrical power system having a receptacle for recharging said battery, said electrical power system having two electrodes at said nozzle, said two electrodes having a gap therebetween, said gap being directly across the open end of said nozzle, said high voltage spark occurring across said gap, said high-voltage being established by the operation of second trigger member, said second trigger member being directly under distal end of said first trigger member.
Claim 6
Dependent Claim 17 words
The electro-mechanical chemical firearm device as recited in claim 3, wherein said fuel is an ether compound.
Claim 7
Dependent Claim 45 words
The electro-mechanical chemical firearm device as recited in claim 1, and additionally, one end of said hollow handle means being removably attached for installation of other mechnaisms therein, and one end of said hollow barrel means being removably attached for installation of other mechanisms therein.
Claim 8
Dependent Claim 28 words
The electro-mechanical chemical firearm device as recited in claim 1, and additionally, said hollow handle means surmounted on said hollow barrel means has an approximate automatic pistal configuration.
