lVithin the electrical circuit are suitable switches, which latter are situated within ready access to the cashier or teller so that when said switch is closed, the resistance element being energized will ignite the combustible mixture and cause the temporary incapacitating agent to be projected under pressure in a plane immediately in advance of the window as will be readily understood from Fig. 2 of the drawings.

In the modifications shown in Figs. 4: to 7 of the drawings there is disclosed a gas generator and dispersing means wherein the outlet passages (A) extend radially from the cartridge chamber (2). This chamber is closed by a threaded plug (11) suitably threaded in the open end (12-) of the generator as clearly shown in Fig. 4. Plug (11) is centrally bored for passage of the conductors (13) connected to resistance (14) located in the combustible mixture of the cartridge.

The preceding structure, while quite analagous to that originally described has been found to be more advantageous under certain circumstances in efiecting dispersion of the as. i a In conclusion it is manifest this invention provides a simple, easily charged generator which may be mounted above the window so that when set into operation, the gas discharging through the outlets will completely envelope the bandit standing in front of the window to render him helpless and permit of his ready capture.

Having thus described my invention, what I desire protected by Letters Patent is as set forth in the following claims j 1. A gas protective apparatus comprising a gas generator and means in connection therewith for producing a vertical sheet of gas immediately beneath the generator said means including a body portion having a cartridge chamber, a gas producing cartridge disposed within the chamber, means for igniting the cartridge and a plurality of outwardly and downwardly directed gas conduits extending from the cartridge chamber to the exterior of the generator through the bottom of the body portion, the outlets of the conduits being so arranged as to merge the gaseous discharge into a solid sheet.

2. A gas protective apparatus comprising a gas generator and means in connection therewith for producing a vertically disposed sheet of gas immediately beneath the generator, said means including a body portion having therein a longitudinally disposed cartridge chamber, a gas producing cartridge fitted within the chamber, means for igniting the cartridge and a plurality of outwardly and downwardly directed gas conduits communicating with the cartridge chamber along the length thereof and extending to the exterior of the generator through the bottom of the body portion, the outlets of the conduits being arranged so as to merge their gaseous dischargesinto a solid sheet.

.3. A gas protective apparatus comprising a gas generator and means in connection therewith for producing a Vertical sheet of gas immediately beneath the generator, said means including a body portion having a cartridge chamber, a gas producing cartridge disposed within the chamber, electric means in connection with the cartridge for eliiecting its ignition and a plurality of outwardly and downwardly directed gas conduits extend. ing from the cartridge chamber to the ex terior of the generator through the bottom of the body portion, the outlets of the conduits being so arranged to merge the gaseous discharge into a solid sheet.

4. A gas protective apparatus comprising a gas generator and means in connection therewith for producing a vertcal sheet of gas immediately beneath the generator, said means including a body portion having a discharge outlet in its bottom, a gas source located interior of the body portion and means for conducting the gas from said source in an outwardly and downwardly curved path to the discharge outlet, whereby the gaseous particles issuing from the outlet will tend to remain in a vertical plane.

5. A gas protective apparatus comprising a gas generator and means in connection therewith for producing a vertical sheet of gas immediately beneath the generator, said means including a body portion having a discharge outlet in the bottom thereof, a source of gas located interior of the body portion and an outwardly and downwardly curved conduitinterconnecting the gas source with said outlet, whereby the motion imparted by the curved conduit to the gaseous particles traversing it will cause said particles, after leaving the outlet, to remain in a vertical plane.

6. A gas protective apparatus comprising a gas generator and means in connection therewith for producing a vertical sheet of gas immediately beneath the generator, said means including a body portion having a series of discharge outlets formed in the bottom thereof, a source of gas supply interior of said body portion and a plurality of outwardly and downwardlycurvecl conduits interconnecting the source of gas supply with said discharge outlets, whereby the motiontransmitted to the gaseousparticles traversing the conduit will tend to restrict said particles, afterleaving the outlets to a vertical plane.

7. A gas protective apparatus shaped to conform to the general configuration and constitute a portion of the supporting fixture upon which it is adapted to be mounted and comprising a gas generator and means in connection therewith for producing a vertical 5 sheet of gas immediately beneath the generator, said means including a body portion having a plurality of aligned discharged outlets in its bottom, a gas source located interior the body portion and means for conducting the gas from said source in an outwardly and downwardly curved path to the discharged outlets whereby the gaseous particles issulng from the outlets will tend to remain in a vertical plane.

8. A gas protective apparatus shaped to conform to the general'configuration of and harmonize with the supporting fixture upon which it is adapted to be mounted, said means including a body portion having a series of aligned outlets extending longitudinally thereof, a gas source located interior the body portion, means for conducting the gas from said source to said outlets and means in connection with the last-mentioned means to impart a downward movement of the particles as they issue from the outlets whereby said gaseous particles will tend to remain in a vertical plane.
