2 Sheets-Sheet 2 86 I INVENTOR 92 1 96 WILLARD L. PETERS I v BY OLDHAM a OLDHAM FIG. 8 ATTORNEYS MONEY SPRAY APPARATUS FOR THEFT IDENTIFICATION The present invention relates to a device for spraying an indelible dye or other marking fluid on the contents of a cash register drawer in the event of an attempted theft of the contents. The markings provide means for identifying the stolen currency and thus aid both in the recovery of the currency and in the apprehension of the thief.

It is the primary object of the present invention to provide a device for spraying a marking material on the contents of a cash register drawer upon unauthorized removal of such contents.

It is also an object of the invention to provide such a marking device which is inconspicuous when installed in the cash register drawer so that the thief is unaware of the presence of the device and does not attempt to deactivate the device.

Another object of the invention is the provision of a marking device for a cash register drawer which is fast acting.

A further object of the invention is the provision ofa device for marking for identification of the contents of a cash register drawer which may easily be installed in existing equipment.

Yet another object of the invention is the provision of a marking device for a cash register drawer which is of simple construction and reliable operation.

The above and other objects of the invention which will become apparent in the following detailed description are achieved by providing a contents marking device for a cash register drawer which consists, essentially, of an aerosol container of a dye or other marking fluid housed in an inconspicuous location in a cash register drawer, a distribution manifold for receiving the fluid from the aerosol container and distributing the fluid to individual nozzles in separate compartments of the container, and an actuating mechanism for the aerosol container which consists of an actuating lever for contacting the nozzle of the container, a rod connected to one end of the lever and biased by a compression spring to move the lever to its actuating position, a spring clip on the rod to normally hold the spring in its compressed position, and a connection to the currency holding fingers of one of the compartments of the cash register drawer for releasing the spring clip when the fingers are raised.

For a more complete understanding of the invention and the objects and advantages thereof reference should be had to the following detailed description and the accompanying drawings wherein there is shown a preferred embodiment of the invention.

In the drawing:

FIG. 1 is a perspective view of a cash register showing the drawer thereof in its open position;

FIG. 2 is a perspective view of the tray of the cash register drawer of FIG. 1, showing the contents marking device of the present invention installed in the tray;

FIG. 3 is a perspective view of the spray container and actuating mechanism housing of the assembly of the present invention;

FIG. 4 is a transverse sectional view taken along the line 4-4 of FIG. 3;

FIG. 5 is a plan view of the spring clip and flexible connection to the currency holding fingers of the cash register drawer tray;

FIG. 6 is a fragmentary sectional view taken along the line 6-6 of FIG. 4;

FIG. 7 is a transverse sectional view similar to that of FIG. 4, but showing a second embodiment of the invention; and

FIG. 8 is a schematic showing of the control circuit employed with the embodiment of FIG. 7.

The cash register 10 of FIG. 1 may be a conventional cash register which has a cash drawer l2 fitted with a compartment tray 14. The tray 14 is divided into a first series of small compartments 16-1611 for receiving various denominations of coins and to a second series of larger compartments 18-1811 for receiving various denominations of paper currency. Each of the large compartments 18-1811 is equipped with currency holding fingers 2020d, respectively. As is shown in FIG. 2, these fingers 2020d may be substantially M-shaped having side legs 22 which are received in brackets 24 on the side walls of the compartments and a center section 26. A spring 28 is connected to the mid-point of the center section 26 of each of the fingers 20 and to the rear wall 30 of the tray to bias the fingers downwardly against the floor of the tray 46 thus clamping the paper currency in the compartment. The tray thus far described is of conventional construction.

Housed within the rear portion of one of the compartments 18 is an enclosure 32 which, as will be described in more detail below, contains an aerosol container and an actuating mechanism therefor. A distribution manifold 34 extends along the back of the tray 14 and has a lateral conduit 36 in each of the compartments 18a-18d. The lateral conduit 36 extends along the bottom wall of the compartment, closely adjacent one of the side walls thereof, and terminates in an upwardly extending nozzle or discharge member 38, with spray openings in its side.

The enclosure 32 is shown in greater detail in FIGS. 3 and 4 and consists of a main portion 40 and a cover plate 42 which is bolted to the main portion 40 by the screws 43 and which includes a flange 44 having holes 45 to receive screws connecting the enclosure 32 to the floor 46 of the cash drawer tray 14. The aerosol container 48 is received within the main portion 40 of the enclosure 32 and has a nozzle 50 at one end which is connected by a flexible tube 52 to the end of the distribution manifold 34. The aerosol container 48 is of conventional construction and of the type which is activated by pressing the nozzle 50 toward the body portion of the container 48. The container 48 is filled with an indelible dye of any other suitable marking fluid. The dye provides a means for subsequently identifying the stolen currency. A dye which is invisible under normal light but visible under ultra-violet light may be em ployed to prevent detection by the thief.

Adjacent the end wall 53 at the valve end of the aerosol container 48 there is provided an actuating lever 54 which is hinged by a pin 56 carried on lugs 58 bent from the wall 53. The actuating lever 54 contacts the end of the valve 50. The end of the actuating lever 54 opposite the hinge connection 56 has a hole at 60 to receive the end of a rod 62 loosely. The rod has a peened over end 64 to retain it in engagement with the hole 60 in the actuating rod 54. The rod 62 extends generally at right angles to the actuating lever 54 and has its opposite end slidably received in a tube 66. The

end of the rod within the tube 66 is provided with an enlarged annular portion 68 and a compression type coil spring 70 surrounds the portion of the rod 62 within the sleeve, the spring being retained between the annular portions 68 of the rod 62 and the end portion 72 of the sleeve 66. The opposite end of the sleeve 66 is flanged so that it is retained against the opposite end wall of the main portion 40 of the enclosure 32. The rod 62 has an annular groove 75 on which is received a spring clip 76. The groove 75 is located so that when the clip is in place, the spring 70 is compressed and the actuating rod 54 is held away from the aerosol valve 50. When the spring clip 76 is released, in a manner to be described below, the spring 70 expands moving the rod 62 into the sleeve 66 thus pulling the actuating rod against the valve 50 and releasing the fluid from the container 48. A wire or other flexible member 78 is attached to the spring clip 76 and extends through a hole 80 in the cover plate 42 of the enclosure 32. The opposite end of the wire or flexible member 78 is connected to a hook 82 which is received at the mid-point of the center section 26 of the paper holding finger of the compartment 18. The length of the wire or flexible member 78 is such that when the paper holding finger 20 is raised the wire 78 is pulled taught, pulling the clip 76 off of the rod 62. Thus it can be seen that when the device is installed in the cash drawer tray 14, lifting of the paper fingers 20 will actuate the spray mechanism, marking the currency in each of the compartments ofthe tray 14.

A second embodiment of my invention which employs a solenoid release for the aerosol container in place of the compression spring arrangement described above is illustrated in FIGS. 7 and 8. Components of the second embodiment which correspond to those of the first embodiment are identified by the same reference numeral with the suffix 11" added.

A solenoid 86 is housed within the enclosure 40a adjacent to the aerosol container 48b. The movable rod 88 of the solenoid 86 is connected to the free-end of the nozzle actuating lever 54a. When, as is shown in FIG. 7, the solenoid 86 is deenergized, the rod 88 is fully extended and the actuating lever 54a does not contact the nozzle 50a of the aerosol container 48a. Energization of the solenoid causes the rod 88 to move into the solenoid, moving the lever arm 54a so as to depress the aerosol nozzle 50a and release the dye fluid into the manifold 34a which, as in the previously described embodiment, leads to individual spray nozzles in the compartments of the cash drawer tray.

One possible actuating circuit for the solenoid 86 is shown schematically in FIG. 7. It will be understood that other circuit arrangements well known to those skilled in the art may be used to achieve the desired result. The circuit includes a current source 92 which is in series connection with the solenoid 86, a normally closed switch 94, and a normally open switch 96. The switch 94 is a manually controlled switch which is preferably located at an inconspicuous place on the cash register. This location should be known only to the authorized users of the register. The switch 94 permits the actuating circuit to be de-energized allowing normal use of the cash drawer. The second switch 96 is adapted to close upon the occurrence of an action of unauthorized entry to the cash drawer or unauthorized removal of the contents of the drawer. For example, the switch 96 may be connected to one of the currency holding fingers 20 so that lifting of the finger closes the switch 96. Alternatively, the switch 96 may be housed in the cash register in such a manner that opening of the drawer l2 closes the switch 96.

All of the components shown in FIG. 8 could be located in the cash drawer.

Preferably, the compartment 18 which houses the enclosure 32 is baited, for example by placing one large denomination bill on the top of a stack of paper, so that the thief is encouraged to raise the paper fingers 20 of the first compartment 18 before he attempts to remove the currency from the other compartments. A suitable cover plate 84 may be provided across the top of the back portions of each of the compartments 18-18d so that the enclosure 32 is not readily visible. The device is thus substantially completely concealed.

Slide contacts could be used between the cash register and the cash drawer to transmit power to the cash drawer from an external power source.

Since only a minimum amount of modification of the structure of the drawer is required to install the marking device of the present invention, the device may be easily installed in existing equipment. To do so, it is merely necessary to provide two holes in the floor 46 of the tray 14 to receive the screws which mount the enclosure 32 and a hole through each partition to receive the distribution manifold 34.
