Abstract
Abstract A hand gun and cartridges therefor, each cartridge being provided with a charge of tear gas or other toxic substance. The gun is generally of elongate compact configuration and is provided with a breech section defining a chamber for receiving tear gas cartridges. The gun includes an elongate stock portion of a size adapted for gripping in the palm of the hand of a user and thumb operative plunger means for selectively discharging a cartridge chambered in the breech section of the gun, and includes a sliding shield member translationally adjustable between positions covering and uncovering the breech chamber.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
235 words
Tear gas disseminating fire arm means for self-defense use comprising a tear gas cartridge including a casing, a loading of toxic substance contained in the casing, a chArge of explosive propellent material, and percussion primer and propellant means for discharging the toxic substance from the cartridge casing; a hand gun for selectively discharging the cartridge and directionally projecting a discharge blast of the toxic substance, said gun being of elongate form and having forward and rearward ends and front and back sides, and including a body having breech, muzzle and stock sections arranged generally coaxially, with said breech section defining an elongate chamber transversely U-shaped, opening to the front side of said gun body and adapted for receiving a cartridge in movement laterally of the axis of the breech chamber, said fire arm means including nozzle defining a blast opening communicating with the breech chamber for projecting the toxic substance, a shield member, finger-manipulative and operative selectively for covering and uncovering the breech chamber, a plunger having a tip portion, means guidingly constraining said plunger in the stock section of said gun body in a disposition permitting axial movement between a retracted disposition with the plunger tip distant from the cartridge primer, to an extended disposition engaging the tip with the primer, spring means forcibly urging said plunger to an extended position, and knob means connected with said plunger for retracting and releasing the plunger.
Claim 2
Dependent Claim
235 words
Tear gas disseminating fire arm means for self-defense use comprising a tear gas cartridge including a casing, a loading of toxic substance contained in the casing, a chArge of explosive propellent material, and percussion primer and propellant means for discharging the toxic substance from the cartridge casing; a hand gun for selectively discharging the cartridge and directionally projecting a discharge blast of the toxic substance, said gun being of elongate form and having forward and rearward ends and front and back sides, and including a body having breech, muzzle and stock sections arranged generally coaxially, with said breech section defining an elongate chamber transversely U-shaped, opening to the front side of said gun body and adapted for receiving a cartridge in movement laterally of the axis of the breech chamber, said fire arm means including nozzle defining a blast opening communicating with the breech chamber for projecting the toxic substance, a shield member, finger-manipulative and operative selectively for covering and uncovering the breech chamber, a plunger having a tip portion, means guidingly constraining said plunger in the stock section of said gun body in a disposition permitting axial movement between a retracted disposition with the plunger tip distant from the cartridge primer, to an extended disposition engaging the tip with the primer, spring means forcibly urging said plunger to an extended position, and knob means connected with said plunger for retracting and releasing the plunger.
Claim 3
Dependent Claim
28 words
Tear gas fire arm means as set forth in claim 1 which includes plunger lock means selectively operative for releasably fixing said plunger in a partially retracted configuration.
Claim 4
Dependent Claim
105 words
Tear gas fire arm means as set forth in claim 2 wherein said knob means includes a knob portion and a shank portion connecting the knob portion with said plunger, wherein the front side of the gun body stock section is provided with slot structure guidingly receiving the shank portion of said knob means, including a main longitudinal slot guidingly constraining the knob means during retracting and releasing the plunger, and wherein said plunger lock means includes a lock notch laterally intersecting said main slot for removably receiving the shank portion of said knob means in releasably fixing said plunger in the partially retracted configuration.
Claim 5
Dependent Claim
29 words
Tear gas fire arm means as set forth in claim 3 including a lug protruding slightly from the interspacial lateral boundary of the blast opening of said muzzle section.
Claim 6
Dependent Claim
71 words
Tear gas fire arm means as set forth in claim 1 wherein said blast opening is transversely U-shaped and arranged in corresponding alignment with the U-shaped breech chamber, wherein said shield member is sleeve-like and configured for sliding shifting fit on the muzzle section of said gun body, and adapted to be axially manipulated between retracted active configuration covering the breech chamber, and an extended inactive configuration uncovering the breech chamber.
Claim 7
Dependent Claim
36 words
Tear gas fire arm means as set forth in claim 5 including detent means operative between said shield member and muzzle section for releasably holding said shield member in an active configuration covering the breech chamber.
Claim 8
Dependent Claim
83 words
Tear gas fire arm means as set forth in claim 6 wherein said shield member includes an annular main portion circumferentially arranged about said body muzzle section and wherein said detent means includes a resilient tongue portion extending rearwardly from said main portion of said shield member, and includes mating tit and dimple surfaces formed respectively on said tongue and breech portions, adapted for detent-mating engagement when said shield member is in a retracted active configuration covering the chamber of said breech section.
Claim 9
Dependent Claim
60 words
Tear gas fire arm means as set forth in claim 7 wherein said shield member is provided with a pair of slot openings intersecting the rearward edge of the shield member and with the parent material of the shield member, between the pair of slots, being of resilient plastic character and forming the resilient tongue means of said detent means.
Claim 10
Dependent Claim
70 words
Tear gas fire arm means as set fOrth in claim 8 wherein said pair of slot openings formed in said shield member, in addition to providing spring tongue means for said detent means, also provide weakened areas in the circumferential structure of said shield member, permitting disuniting of the shield member at the weakened areas upon the discharge of an explosive force in said breech chamber exceeding a certain magnitude.
Claim 11
Dependent Claim
75 words
Tear gas fire arm means as set forth in claim 1 wherein said gun is configured for simultaneously chambering two tear gas cartridges, and includes means independently operative for selectively discharging the cartridges, wherein said gun includes dual breech chambers, nozzle openings, plungers and knob means, and wherein said shield member is configured for simultaneously covering or uncovering the dual breech chambers upon selective axial manipulation of the shield member between active and inactive configuration.
