In my copending application 464,992, above.

tempting a hold-up robbery in a bank, store, i The sys-:

money-exchanging windows, etc. tem described therein. contemplates discharging a group of gas shells or shells which will deliver mixed gas and smoke, or individual gas shells and smoke shells, simultaneously by the closing of an electric contact'by the bank clerk, the discharged gas, or gas'and smoke, either separately or mixed,'being of considerable volume sufiicient to overcome and incapacitate a number of people who may i be in the bankcorridor at the time. The p0-- lice are then notified and the bandits captured; after a short time, the disabling ef-. fects of the gas will pass off and the incapacitated persons are not injured,

In Fig. 1, anelectric gas shell is shown,

the outer tube 1, ofwhich contains asealed fragile holder 2 filled with asuitable irritating gas charge 3, a diaphragm 4, a charge or explosive 5, a ferrule 6, a base 7, terminal posts 8, an electric .fuse 9, and a shunt 10. In this modification, the shunt 10 is shown as imbedded in the explosive 5. Details of the base 7 fuse 9, and shunt 10 are shown on an enlarged scale in Fig. 2. TheshuntlOis also used in Figs. 16 and 17.

In the modification shown in Fig. 3, the shunt 11 is placed in a recess in base 17 in order to protect it from the heat generated by the firing of the explosive 5; the ends of.

the shunt are connected to :posts 8/ The shunt 11 is for the purpose of maintaining an uninterrupted circuit through a group of gasshells connected in series, as above noted. The shunt 11 may also be used with Figs. 16 and 17. r t

In the modification shown in Fig. 4, the socket 15 is provided with a-shunt 16, having its terminals connected to the socket contacts 1818. In Fig. 5 is shown a group of sockets 19 connected to theelectric wires 20 which supv ply electric current thereto.

In Figs. 6, 7, 8, 9, 10, and 11, are shown systems of omnibus gas distributing parts with the'gas shells 35, 36, attached thereto, the gas to be discharged from the shell into the distributing -pipes 21 from which it passes through suitable orifices, jets, sprays, etc., 28 and is directed thereby where desired. In Fig. 6, an expansion chamber or omnibus pipe 21 is provided with a suitable connec tion to receive a gas'shell 35, for example, a

bayonet connection 22 may be-used, and a gas cartridge 35 inserted therein,-withthe closed at the other end; insteadof the bayonet slot 22 any other type of joint may be used as for example a screw threaded joint. The pipe 21 is provided with outlets which may be holes 23, or nozzles 24, which nozzles may have special types of jets 25, 26, such as shown in Figs. 10 and 9, to discharge the as blast into a spray, sheet, or curtain" 40, or other form of discharge. An eflicient type of nozzle is shown in Figs. 22 and 23, Fig. 22 illustrating the front View of a plate or rosette which may be secured direct to the omnibus pipe 21, over holes 23; or may be attached to the discharge end of the nozzle 26. The plate 71 is provided with a multiplicity of angularly drilled holes 72, Fig. 23, and a central hole 73; the angularly drilled holes 72 spray the gas as a diverging cone, and produce an effective gas and smoke cloud. The nozzles 24 are placed sufficiently close together so that the discharging gas blasts are preferably mixed with each other to form a cloud or curtain of gas, and when the pipes 21 are located in an elevated position the nozzles may be directed downwards, as in Figs. 12 and 14. The pipe 21 may be suitably curved as in Fig. 8, to fit on various types of moldings, ornamental fittings, grill work, etc., 30, 31, and 32 as shown in Figs. 12, 13, and 14, and may also be constructed with pipe fittings 28 as in Fig. 11, to form suitable angles to fit around corners, etc. In relatively short omnibus gas pipes one gas cartridge 35 may be attached to the pipe at a suitable place, for example at one end, as in Figs. 6, 8, and 21; or with longer pipes, two or more gas cart-ridges 36, 36, may be secured thereto where desired as in Figs. 7 and 11. The gas cartridges 35, 36 are provided with pins 37 as shown in Fig. 15, to connect with the pipes 21, and after firing, the exhausted gas shells are replaced by new ones. The several gas shells 35, 36, in an installation are electrically connected in series by attaching a group of series connected sockets 19, such as is shown in Fig. 5, and are discharged by closing a contact (not shown) when the necessity arises. The shunts 10, 11, 16, serve to maintain a permanently unbroken circuit through all of the series connected gas shells.

In Fig. 16, the explosive charge 45 is mixed with a chemical smoke producing charge 46; in Fig. 17 the chemical smoke producing charge 47 is in a separate compartment 48, the shells in Figures 16 and 17 are otherwise like that shown in Figs. 1 and 15, including the shunt 10 or 11, of Figs. 1 or 3. and may be used in place of the shell shown in Fig. 1, in the omnibus pipe systems shown in Figs. 6 to 11, and in Fig. 21.

In Figs. 18 and 19 are shown omnibus pipes 50 and 51, to which are attached Y couplings 52, or equivalent connections to receive two shells 53, 54; the shell 53 may be a gas shell such as that shown in Fig. 1, and the shell 54 may be a well-known standard type of chemical smokeproducing shell; both shells being discharged into the omnibus pipes, and the mixed gas and smoke issuing from the outlet jets 55 into the bank room or jewelry store, etc. The mixed gas and smoke cloud will both incapacitate and obscure'the vision of the bandits, and prevent them from executing the robbery should they be wearing gas masks as a protection against the irritating gas. The cartridges 53 and 54 may be replaced after they have been discharged, as described above.

In Fig. 20, is illustrated diagrammatically a bank room 61, or jewelry store, or other place where money or valuable property is handled, with the usual bank cages, money-changing windows, jewelry cases, etc. 62. Suitably located upon the partition 63 of the bank cages 62 are placed pairs of shells, 64, 65, one of which 64, is an individual gas shell, and the other 65, an individual chemical smoke shell; the shells to be electrically connected as shown in Fig. 5, both actuated by a single contact, and operated preferably by the system described in my earlier application, Serial No. 464,992, above noted; and when discharged, filling the bank room or jewelry store, or other place where money or valuables are handled, 61, with a mixed gasand smoke cloud.

Instead of using individual shells as shown in Fig. 20, the several bank cages, or jewelry counters, or pay windows, 62, may be supplied with an omnibus pipe, with an outlet at each cage or jewelry counter as shown in Fig. 21. The omnibus pipe 21 shown in Figs. 6 and 8, and at 67 shown in Fig. 21, may be located upon the several bank cages, etc., in the bank room or store 66, with outlets 23, 24, and 69, at each bank window, or jewelry counter, etc., thereby protecting several bank cages, or similar money or valuable property displaying places, with a discharge of one gas shell 68 through the omnibus pipe 67 this arrangement reduces the cost of installation and operation, and also reduces the possibility of the protection system getting out of order.

In the protection system described herein, either gas shells, or shells which deliver gas and smoke, or separate gas shells and smoke shells, may be used; and by the terms disabling gas or disabling gas and smoke is meant an irritating, asphyxiating, and disabling gas such, for example, as tear gas etc., also chemical smokes such as are used to produce opaque atmospheres, etc., the function of which latter is to obscure the vision of the bandits and to enable the bank clerks or others to sound the alarms and call the police, and also to delay the escape of the bandit-s.

I claim:

1. In a system of gas protection against robbery, the combination of a plurality of expansion chambers into which an irritating gas is discharged, a multiplicity of distributing outlets from each of said expansion chambers, said expansion chambers having a rela- 'ively large diameter compared With the outlets, gas shells detachably connected to the inlet ends of said expansion chambers, said gas shells electrically connected in series, and a shunt cooperating with each of said gas shells to maintain an unbroken circuit through all of the said gas shells.
