Definitions

  • Valuable paper such as paper currency is maintained secure by pressing bundles of paper in edgewise abutting relation against at least one pyrogenic chemical element which is disposed in the bottom of a receptacle and which is adapted when burning to heat paper above its charring temperature, providing an igniting electric element that will ignite the pyrogen upon a change in position of at least a portion of the receptacle, and thereafter maintaining that position unchanged.
  • the bundles are 20 spaced from each other and are pressed independently in a plurality of packs against the pyrogen.
  • the present invention relates to a method and apparatus for maintaining the security of valuable paper such as paper currency, and more particularly for ensuring that valuable paper such as paper currency which is attemptedly stolen will be destroyed in the theft to the extent that it cannot be spent.
  • FIGURE 1 is a perspective view of a device according to the present invention.
  • FIGURE 2 is an enlarged fragmentary side cross-sectional view of a portion of the apparatus of the present invention, showing one form of actuator structure therefor;
  • FIGURE 3 is a view similar to FIG. 2 but showing another embodiment of actuator structure
  • FIGURE 4 is a view similar to FIGS. 2 and 3 but showing still another form of actuator structure.
  • FIGURE 5 is a somewhat diagrammatic perspective view of a modied form of marking element according to the invention.
  • the present invention comprises the discovery that valuable paper such as paper currency can be indelibly and unmistakably marked at the time of theft, if it is stacked in edgewise abutting relationship against a heating element which is actuated by the act of theft.
  • the heating element burns or chars the edges of all the sheets in the stack, to an extent that cannot be concealed upon subsequent efforts to pass the paper.
  • the heating element is disposed in a receptacle, and preferably a portable receptacle, provided with means maintaining the heating element inactive during intended handling of the receptacle but having means for actuating the heating element upon a handling of the receptacle that is characteristic of theft.
  • a receptacle comprising a small trunk or carrying case having a lid 1 lined with an asbestos sheet 2.
  • the carrying case has a body 3 whose lateral walls and bottom are also lined with asbestos sheets 4 and 5, respectively.
  • a number of ignition rods 6 are disposed parallel to each other and are spaced apart and extend along the base or bottom or body 3 of the carrying case.
  • These rods are comprised of any pyrotechnic mixture adapted to burn quickly with a high combustion temperature. Preferably, they release abundant fumes upon burning, which may or may not be colored as desired, or of penetrating odor or suifocating, so as to call attention to or identify the fumes.
  • These pyrotechnic mixtures are of known composition and burn in the absence of atmospheric oxygen. They can be of sulfur or other known pyrogens. They can be standard pyrotechnic igniters used for decoy mines.
  • the carrying case is provided with small perforations for the escape of fumes without sundering the case.
  • Ignition devices for the rods are provided in the form of electrical resistance igniters 7 having electrical conductors 8 by which the rods are electrically conducted to a current source (not shown) that provides electrical resistance heating of igniters 7 to at least the ignition temperature lof the rods 6.
  • Paper currency 9 or other valuable paper is placed in bundles resting on their edges on rods 6, as seen in FIG. 1.
  • the edges of the sheets extend transversely of the rods.
  • the bundles are rmly pressed against the rods by bands 10 of rubber or other elastic material, carried by the case and encompassing the sheets.
  • a control compartment 11 is provided, insulated by asbestos sheets 12 so that the contents of the control compartment will not be damaged upon ignition.
  • a push button 13 is carried by compartment 11, which is continuously yieldably urged upwardly but which is pressed down by the cover of the carrying case when the case is closed.
  • the push button 13 is connected to an electrical contact (not shown) which is in series with igniters 7, so that when the cover is opened and push button 13 is raised, the circuit to igniters 7 is opened and ignition cannot take place.
  • the person storing paper in the case or removing it from the case can operate in complete safety. It is only when the cover is lowered and the case is closed that ignition can be effected by means to be described hereinafter.
  • the compartment 11 also carries a signal lamp 14 which is ignited when the cover is opened and the corresponding batteries 14a shown in FIG. 2 are well charged.
  • Signal lamp 14 is also in circuit with the contact of push button 13 so that lamp 14 is on when push button 13 is raised in the position of FIG. l but is turned olf when the cover is closed and bush button 13 is depressed.
  • the ignition circuit for igniting the igniters 7 may be energized in any of a variety of ways.
  • Electronic means (not shown) may be used to initiate the powering of the circuit that includes batteries 14a.
  • Wave signals such as Hertzian or ultrasonic may be used to effect ignition through appropriate relay means (not shown).
  • An emitter and a receiver (not shown) can be used, one on the carrying case and the other at some point such as on the bearer of the carrying case or in the vehicle for transporting the carrying case, such that an increase in distance between the receiver and the emitter above a predetermined maximum will trigger ignition.
  • an emitter of ultrasonic or other waves can be ⁇ mounted at a reference point and a tuned receiver can be disposed in the carrying ease, the signal emitted by the emitter exciting the receiver and thus keeping open the contact of a relay when the distance between the emitter and the receiver does not exceed a predetermined maximum.
  • FIG. 2 the compartment 11 is shown as enclosing not only the batteries 14a which power the ignition circuit, but also a cylinder 15 in which is slidably mounted a striker 16 urged downwardly by a spring 17 and secured at one end to a flexible wire 1S which passes through the wall of the body 3 of the carrying case and is fixed to the pivot 19 of the handle 2t) of the carrying case.
  • a rupture plate 21 is disposed below the striker 16.
  • Two electrical switch contacts 22 are normally spaced apart but are movably mounted to be pressed together by striker 16 upon the destruction of rupture plate 21.
  • a glass tube 23 containing mercury 24 and two spaced contacts in series in the circuit of the igniters there are provided a glass tube 23 containing mercury 24 and two spaced contacts in series in the circuit of the igniters.
  • the circuit to the igniter is open. But when the case is tilted or laid fiat, with the lid closed, the mercury establishes electrical contact between the two contacts 25 so that ignition is effected.
  • a contact body 26 is slidably mounted in an insulated tube 27.
  • Body 26 carries a guide collar 28 at its one end and a collar 29 at its other end.
  • Collar 29 is of an electrically conductive metal such as brass.
  • Body 26 is urged by a spring 30 downwardly as seen in FIG. 4 but is connected by a rod 31 to a flexible wire 32 which is xed at its other end to an external point, such as a ring or a bracelet on the person carrying the case.
  • Two contacts 33 connected in the electric circuit of the igniters, are fixed in the tube 27 and project from the interior wall thereof.
  • Ignition can of course be effected in other ways, For example, an electric wire (not shown) in a holding or control circuit can be ruptured. Moreover, if desired, a sound warning system may also be initiated by theft at the same time that ignition is effected
  • FIG. 5 there is shown a modified form of igniter rod, in which the rod has sloped edges along which is disposed a series of holes 33a.
  • the spacing between the holes in each row is about the same as the thickness of a bundle or paper it is desired to transport.
  • a metal wire 34 is disposed at each of its ends in a hole 33a, and the bundles are individually disposed between adjacent pairs of wires 34. With the bundles thus slightly spaced from each other, the edgewise abutting contact of the bundles on the ignition rods is made more certain and the chances are reduced that a bundle can become wedged between two other bundles out of contact with the ignition rods.
  • the device of the present invention is reusable. All that needs to be done is to replace and reconnect the spent ignition rods.
  • a method for maintaining the security of valuable paper comprising pressing bundles of valuable paper in edgewise abutting relation against at least one pyrogenic element disposed in the bottom of a receptacle and adapted when burning to heat paper above its charring temperature, establishing an open electric circuit which when closed ignites said pyrogenic element and which closes upon a change in position of at least a portion of the receptacle, and thereafter maintaining said position unchanged.
