Description
9~, I
BACKGROUND OF INVENTION
. . _ (a) Field of Invention , The present invention relates to an anti-theft marking system and preferably, but not exclusively, for marking the glass panes of a vehicle.
(b) Description of Prior Art A method is presently known for marking the glass panes of a vehicle. However, such method utilizes abrading tools which act directly on the glass of a vehicle and which are guided by a thick template. Such method has been found very expensive and time consuming to use. Furthermore, these templates are used over and over again to mark the various panes of a vehicle and therefore can induce fraud by permitting the marking of several vehicles with the same code, thus defeating the ; purpose of the method which is to identify a vehicle with its proprietor to protect same.
SUMMARY OF INVENTION
It is a feature of the present invention ~o provide an anti-theft marking system which overcomes the disadvantages of the above-mentioned prior art.
Another feature of the present invention is to provide an anti-theft marking system which is less costly than that known in the prior art, easy to use, and wherein the code of the labels self-destruct when peeled off the abraded surface.
Another feature of the present inven~ion is to provide an anti-theft marking system for use in marking the window panes of a vehicle.

; According to a broad aspect of the present invention there is provided an anti-theft marking system which comprises a label formed of a sand blasting resistant material and defining a front and rear surface. An adhesive substance is impregnated in the rear surface. A code is cut through the ~
label from the front surface to the rear surface in a code receiving area of the labelO A sand bJasting element having a nozzle through which the sand dust is ejected is also provided. The nozzle is configured to encompass the code receiving area of the label. The sand blasting resistant material is a coded paper having wear resistant fibers. The code is formed by letter(s) and/or number(s) each cut out of the material and having bridge lines formed therein whereby to partly self-destruct the code from the label when it is peeled off a glass surface after use~
BRIEF DESCRIPTION OF DRAWINGS
A preferred embodiment of the present invention will now be described with reference to the accompanying drawings, in which:
FIGURE 1 is a perspective view showing a code made with the label of the present invention as applied to the window panes of a vehicle, FIGURE 2 is a perspective view showing the construction of the label, FIGURE 3 is a ~ragmented section view showing the sand blasting element in use with the label; and FIGURE 4 is a front view showlng the nozzle of the sand blasting element of Figure 3.
DESCRIPTION OF PREFERREl~) EMBODI~IENTS
Referring now to the drawings there is shown in Figure 2 a label 10 which is formed of a sand blasting . resisting material which is a paper amalgam having wear resisting fibers and impregnated with a wear resistant binding substance. The paper is a thin sheet and has delineated thereon a code receiving area 11 in which a code 12 is cut through the material from its front sur-face 13 to its rear surface 14. The code is cut through the resistant material of the label by suitable stamping machinery which does not form part of the present invention but which is obvious to a person skilled in the art. An adhesive substance is impregnated in the rear surface 14. The rear surface 14 is protected by a peel-of wax-coated paper 15.
~he wear resistant material of the label 10 has the qualities of being resistant to abrasion, capable of holding an adhesive substance on a rear surface thereof and can be cut to define clear contour lines for the intergers 12' forming the code 12. As herein shown the intergers 12' are provided with small bridge lines 1 in each of the configuration of the intergers 12' whereby when the label is peeled off some of the intergers will destruct as these small bridge lines will either not peel off at the same time as the label and thus become detached from the label and also cause a portion of the -- 4 -- .
label around the intergers to rip off the label. Thus, the code is self-destructive after a single use.
n a preferred application of the anti-the~t marking system of the present invention there is provided a plurality of these labels with the same code 12 cut therethrough and each label is affixed to a glass pane 17 of a vehicle 18 in a specific area of the pane. The labels are affixed by removing the protective sheet 15 and applying the adhesive surface 14 to the glass panes 17. The labels are then in position for a sand blasting element 19 to be positioned thereover to abrade the glass pane 17. Once the abrasion is done the labels are then removed and the glass panes are permanently coded. The code and the identity of the proprietor of the vehicle are then stored in a memory device for future use. It can be appreciated that by coding a vehicle as such it is a deterrent against theft as it is very costly to remove all of the window panes of a stolen vehicle and to replace them with new panes. Thus it is expected that this method will greatly reduce theft and hopefully also reduce the insurance premiums of vehicles.
Referring now to Figure 3 there is shown the method of abrading the code on the glass pane. A sand blasting element 19 is provided with a nozzle 20 having an orifice 21 through which sand blasting particles 22 are ejected. The orifice 21 is of a sufficient size to be placed over the code receiving area 11 of the label whereby to encompass the code 12 entirely within the nozzle orifice.
The gun 19 comprises essentially a housing 23 having a tube 24 therein having at one end an air jet 25 through which compressed air is ejected via the air line 26 whereby to project the dust particles 22 which are injected into the tube throl~gh the passage 27. A return flow of particles is provided via the conduit 28 and through a return line 29 back to a supply of dust particles (not shown). Thus the particles are projected through the tube 24 and the orifice 21 of the nozzle 20 against the front surface 13 of the label whereby to abrade the glass surface in the open coded ~rea. This spray of dust particles is maintained for a predetermined time to provide adequate abrasion.
The nozzle 20 of the sand blasting element 19 is preferably constructed of a thick rubber material whereby the orifice 21 can be placed in close sealing contact over the label, even if the label is affixed to a surface which is not flat. Also the nozzle element is protected from abrasion by the sand particles or made of a suitable abrasion resistive substance.
It is within the ambit of the present invention to cover any obvious modifications of the preferred embodiment described herein provided such modifications fall within the scope of the appended claims. Although the invention has herein been described as applying a code to the panes of a vehicle, the code could also be applied to other materials such as metal, plastlcs, etc.
