In the present instance, however, these 50 such device of compact form and of light weight shells 3 are provided with electrically operated which may be readily and easily concealed within ignition or discharge means in lieu of the usual a dummy packet simulating a package of curpercussion cap. Also located within the case or rency, or within a jewelry display tray or other housing 2 and hence concealed with the packet easily movable article. is a dry cell battery 5 and a gravity operated elec- 55` tric control switch. In the present instance this control switch is shown as comprising a substantially V shaped tube B disposed in substantial perpendicular position and containing a body of mercury 1 normally positioned at the bend of the tube. This body of mercury is free to flow into either of the upturned arms of the bent tube B when the packet is tilted in either direction. Electric terminals 8 extend within the arms of the tube 6 and are electrically interconnected by the body of mercury 'I when it flows into such arms upon tilting the packet. These terminals 8 are electrically connected with the battery 5 and with the ignition devices of the explosive gas shells 3-3 as illustrated in the diagrammatic view Fig. 3. A switch 9 is preferably though not necessarily included in the circuit whereby thecircuit may be opened and the device rendered safe for handling. The same switch is utilized to connect a signalA lamp IIl in a shunt circuit I I with the batltery and through the terminals of the mercury switch'so that the device vmay be safely tested from time to time to ascertain the condition of the battery. n
The explosive gas shel1`3 and the battery andV control switch with the electrical connection are concealed within the packet by vone or more overlying sheets, the top sheet of winch is preferably a genuine piece of paper currency of any desired denomination. To further disguise the packet andincrease its resemblance to a package of genuine currency, the usual strap I3 bearing indicia commonly employed by banks and nancial institutions is employed about the dummy packet.
The dummy packet thus prepared with the swtch49 adjusted to connect the electrical circuit with the ignition devices of the gas shell 3 K is laid with the packages of genuine currency 'Y on the cashiers desk or inside the tellers cage or it may be placed in the cash drawer or in the safe. Such packet would ordinarily be placed in a position most convenient to the robber in the g event of an attempted robbery. f In grabbing the cuit and discharge the gas shells 3. 5o
packet from the desk or from -thegtellers cage, any decided movement of the packet causes the mercury to flow into one arm or the other of the switch tube 6 and thereby close the electric cir- The robber having the package in his hands at such time receives the full eifect of the discharged gas. Y The V type mercury switch is such that the packet maybe slidingly moved aboutrupon the desk or A, counter and a cash drawer may be pushed to and 55` fro without disturbing the mercury body or causing it to flow into the arms and thereby discharge the gas bombs or shells. The packet may even be tilted to a limited extent in a direction transversely to the planerof the V shaped tube without effecting the discharge of the shell, but any tilting movement such as would occur by the removal of the packet from the desk or counter by a robber and its placement in a pocket or in a Satchel would cause an instant gaseous discharge.
While primarily designed for protection of nancial institutions and for the protection of the cashier rof stores, factories or mercantile establishments and hence preferably embodied in the dummy simulating a package of currency, the invention is not limited to such embodiment. In Fig. V5 there is shown a display tray for jewelry or the like in whichVV the gas shells 3-3 together with the energizing battery Sand switch, may be enclosed and concealed. It is not infrequent that jewelry and diamond robberies are attempted by pseudo customers who may grab a tray of gems or jewelry being displayed and make away with it. By enclosing and concealing within such tray Iii, as illustrated in Fig. 5, one or more gas bombs or shells 3 with the necessary discharge system, such type of robbery can be eifectually prevented and the robber be made to gas himself.
While the mercury type of switch is to be preferred, whether it be of the particular V type as illustrated or of other form, mechanically operated ignition devices may be employed in lieu thereo-f. In Fig. 4 there is shown a gas bomb or shell 3 provided with the usual percussion type of ignitor and a spring actuated iiring pin I5 which is normally held retracted against the tension of its actuating spring I6 by a pivoted detent I'I. This detent I1 is held in operative position by a reciprocatory slide element I 8. A pendulum or Yvibratory weighted arm I9 extends in proximate relation with the reciprocatory member I8 and when moved in one'direction is adapted to engage an arm 20 upon the reciprocatory slide I8 to withdraw such slide out of the path of the de` tent I1. Upon movement of the weighted arm in the opposite direction, such arm has engagement with a lever 2|, which in turn engages a second arm or projection 22 upon the reciprocatory slide to shift such slide I8 out of engagement with the detent II and thereby release the firing pin. Thus the firing pin is released by the movement of the pendulum or the vibratory weighted arm in eitherA direction. This mechanical construction has been shown merely for illustrative purposes and as an indication that the invention is not necessarily limited to the specific mercury control switch in an electrical circuit controlling the gas shells or bombs. The safety switch 9 is easily accessible by removing or turning up thetopmost leaves of the packet. While tear gas or chloracetophenone is the preferred material for loading the shells or bombs and to be discharged by disturbance of the packet, other repellant gaseous or liquid materialmay be employed in lieu thereof.
From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modication in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect and the invention is there-l fore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
