Filed Jan. 26, 1965, Ser. No. 428,096 11 Claims. (Cl. 89-1) ABSTRACT OF THE DISCLOSURE An electrical anti-personnel method and apparatus. The method comprises electrically energizing a stream of conductive liquid and directing the stream at a person. The apparatus comprises a pair of conductive liquid sources, a pair of conduits, a pair of nozzles, and a pair of conductive means contacting the liquid, each pair of elements separate from the other, whereby a pair of oppositely charged streams of liquid may be directed against a person.
This invention relates to a method and to a weapon for the deterrence of hostile persons by electrical means. More particularly this invention relates to a method and to a weapon for transmitting electricity via unconfined streams of electrically charged liquids to persons in remote positions from the operator of such apparatus.
Generally speaking, the method comprises directing at least one unbroken and unconfined, ballistic stream of electrically energized conductive liquid at a remote person for deterring hostile activities and advances by such a person. The apparatus for practicing this method, in general, comprises at least one source of pressurized conductive liquid connected to means for directing said liquid to a remote object in an unbroken stream. Also provided are means adapted for energizing the liquid, such means being adapted for conveying tn electrical current from a power source to said liquid.
Other objects, advantages and features will appear from the following detailed description of the invention taken together with the accompanying drawings, in which. FIG. 1 is a side elevation of apparatus embodying the invention;
FIG. 2 is a rear view of the apparatus shown in FIG. 1;
FIG. 3 is a plan view of the apparatus;
FIG. 4 is an enlarged, fragmentary, side elevation of the apparatus in section;
FIGS. 5, 6, 8 and 9 are circuit diagrams for use in preferred embodiments of the invention; and
FIG. 7 is a fragmetary circuit diagram showing the induction coil of FIGS. and 6 in a circuit broken condition.
Referring now to the drawings, and more particularly to FIGS. 14 thereof, it will be seen that in the preferred embodiment of the apparatus two sources 14, 16 of conductive liquid are provided. In the preferred embodiment the liquid is provided in pressurized containers having electrical insulating, non-corrosive properties, but it is contemplated that the sources may be from any pressure source, such as a pump, provided only that each source be separate and insulated lest there be a short circuit making the apparatus inoperative. The liquid is conductive and may be water containing an electrolyte, such as ordinary sea water or water mixed with sulphuric acid, which has been used successfully. The liquid may also contain thickening or other agents such as methyl cellulose or cellulose gum to prevent too early a break in streams of the liquid.
The liquid sources 14, 16 are connected in pressure sealed relationship to either side of the cross bracket 12 of a preferably pistol shaped device generally designated 10. The bracket 12 includes sealed pressure chambers 33 above each of the liquid sources into which the liquid flows. The chambers 33 each include a seal element at the rear thereof and a valve 31, 32 at the front thereof, the valves each normally being urged by spring means 28 to a closed position. Actuating linkage means for selectively opening the valves 31, 32 are also provided including rods 25, 26 connected at one end to the valves 31, 32 and at their other ends extending through the seal elements 30 for connection to cross rod 27. The actuating linkage means also includes link 24 pivotally connected at one end to the rod 27 and at the other end to a trigger mechanism 22 at a point remote from the upper end of the trigger 22. The trigger 22 is pivotally connected at the upper end thereof to the internal structure of the pistol 10 and at its lower end protrudes from the pistol for digital actuation. On actuation of the trigger the valves 31, 32 are thus opened to permit the flow of liquid from the sources 14, 16.
Leading from the valves 31, 32 at the front of the chambers are conduits 34, 35 leading to simple nozzles 18, 20 adapted for directing the pressurized liquids from the pistol 10 is unbroken, unconfined, ballistic streams. The nozzles are laterally spaced from each other on the bracket 12 and are arranged to provide streams which do not converge within their effective range, i.e. the range at which the streams remain unbroken. Likewise, the nozzles are arranged so that the streams are sufficiently close together as to be capable of simultaneously striking the hostile person against which they are directed. Preferably the nozzles will be arranged to provide parallel streams embodying these limitations but in this specification the word parallel when used to describe such arrangements will be understood to include non-parallel nozzles and streams which embody the foregoing limitations.
Preferably the conduits and nozzles are of materials having electrical insulating properties. Interposed between the conduits and nozzles and disposed for contacting the liquid flowing through the pistol are conductive elements such as tubes 19, 21 adapted to convey an electric charge to the liquid as it flows thereby.
Except for elements 19, 21 and the electrical connections to be described and possibly the trigger 22 and the springs 28, all of the elements of the pistol 10 per se are preferably of non-conductive, non-corrosive materials, for reasons of safety and for the prevention of short circuits. In any event, the liquid sources and elements 19, 21 are insulated from each other and from the external portions of the pistol 10.
Connected to tube elements 19, 21 and extending therefrom through the body of the pistol are wires 42, 44 adapted for conveying electricity to the tubes 19, 21 and hence for energizing the liquids flowing therethrough. Wires 42, 44 extend throughthe handle 56 of the pistol together with wires in the form of a cable 39 and are adapted for connection to a power source generally designated 46.
The power source 46 is preferably portable and adapted to be carried by the operator of the apparatus (not shown). The power source 46 includes wires 40, 41 adapted for connection to a source of either an AC or DC current, preferably the latter and preferably a battery 48. The circuit diagram for the preferred embodiment of the invention is shown in FIG. 5 and includes induction coil 50 for stepping upthe voltage in the secondary circuit, represented by the wires 42, 44, from that in the primary circuit, represented by the wires 40, 41. To permit operation of the coil in the DC current provided in the FIG. 5 embodiment, an iron core 51 is provided in the coil 50 to periodically interrupt the primary circuit, which is normally completed through the armature 52, by attracting the armature 52 as in FIG. 7 away from its contact. Condenser means 54 are provided in the primary circuit between the armature 52 and wire 40 to prevent sparking and undue wear as the armature is actuated. A switch 38 is also provided in the primary circuit for completing and disconnecting the circuit. Preferably this switch 38 is located in the handle 56 of the apparatus 10, wires 40 extending from the power source 46 in cable 39 to the switch 38, and is adapted for completing the primary circuit as the trigger 22 is actuated to open the valves 31-, 32. Preferably the coil 50 may be adjusted, via selector 49 on an accessible portion of the power source 46, to vary the voltage in the secondary circuit.
Alternative arrangements of the circuits are shown in FIGS. 6, 8 and 9 in which the circuits are essentially the same as that in FIG. except that in FIG. 8 an AC current is used permitting elimination of the core, armature and condenser. FIGS. 6 and 9 disclose embodiments in which but a single stream of liquid is energized in which case one end of the secondary circuits is grounded at 45 via wire 44. FIG. 6 otherwise is identical to the circuit in FIG. 8.
To convey an electric charge to a hostile individual, the trigger 22 is actuated to open valves 31, 32 and to close the switch 38 completing the primary electrical circuit. High voltage electricity, which may be varied by means of selector 49, is then transmitted via tubes 19, 21 to the streams of liquid flowing therethrough, preferably each stream having simultaneously an opposite electrical charge. The streams are then directed at the hostile individual whom it is desired to deter provided only that the person be sufficiently close to the apparatus 10, that the liquid streams remain unbroken until contact with the person. Upon contact of the oppositely charged streams with the individual, the secondary circuit is completed through the individual via the oppositely charged streams extending from elements 19, 21 causing at least some discomfort. If but a single stream is energized, proper grounding of the hostile person may be assured to complete the circuit extending from element 19 via the stream to the person by directing sufficient liquid to assure good contact between the person and ground the other end of the circuit being to ground 45 as shown in FIG. 6.
By means of this method and apparatus, therefore, it is possible to provide for deterrence of hostile persons electrically without the necessity of dangerous physical proximity.
