~,METHOD AND APPARA~US FOR ENGRAVING A MARK ON PLANE OR
CURV~D SURFACES
~, , ~Back~round-Field of Invention:
¦The present invention relates to a method and apparatus for engraving in an indelible way a mark formed of numbers and/or letters and/or symbols on a plane or curved surface in order to mark personal belongings such as motor vehicles and the like for anti/theft or identification purposes.
Background-Description of Prior Art:
;J
Marking systems which engrave identification indicia into vehicle windows are coming into widespread us`e. Code systems are utilized with central registries so that if an owner of a marked car needs to be identified, such as when a stolen vehicle is recovered, one can check the code engraved in the windows with such a central register to locate the owner of that vehicle. This coding system can also be used for marking other belongings such as computers, cameras, antiques etc.
, 2 ~ 4 ~3ll The advantage of engraving personal belongings with identification indicia is that it takes a large expenditure of time, effort and money to obliterate or remove such indicia. For example when all the vehicle windows are engraved car thieves usually do not wish to go through such expense and effort of replacing all the windows. Furthermore other parts like the motor, transmission, alternator etc. can also be engraved as a further theft deterrent.
;
The engraving apparatuses described in US patents 3,624,966 to Palmer (1971), 4,048,918 to Peck (1977) and 4,164,183 to Peck (1979) describe sand blasting type marking apparatuses wherein a strong jet of a mixture of compressed air and abrasive granules is directed through stencils against the surface to be marked such as the vehicle's windows thereby , permanently marking the glass.
;`:
~hese apparatuses suffer from the following disadvantages: -J (a) Require long and laborious operations for preparing and '~ assembling the stencils.
,~
(b) Pollute the environment of operation with abrasive dust unavoidably escaping from the apparatus and to dirty ;~ surrounding parts, things or persons presenting a health~!, risk.
,. ~
(c) Escaping abra~ive granules often fall inside the window well of the vehicle and result in the glass being scratched when the window is opened and closed. -, . .
;1, (d) These apparatuses are expensive requiring a large air compressor and special respiratory and eye protection for the `' user.
:., j (e) Can only be operated by specially trained personal.
' ., ~ - :: . : . . :. , :. . : :
r 3 ~ 0 3 ~ ~
(f) Can only mark curved surfaces with very slight curvatures due to rigid stencil construction.
~.~
(g) Are not readily portable since heavy equipment and electricity are required for operation.
. .' .
(h) Due to their high cost and need for special training, they cannot be offered as a do-it-yourself kit.
. ~
Another type of engraving apparatus is described in PCT
.~i patent W0 86/07015 to Cacciotti (1986) and US patents 4,089,262 to Sopora (1978) and 4,834,595 to Cacciotti (1989).
These apparatuses use computer controlled engraving heads to -~ engrave identification indicia onto vehicle surfaces.
Disadvantages of these apparatuses are: -.~. .
(a) The high cost of the special computer and control equipment.
(b) They can only ~e operated by specially trained personnel.
(c) Can only mark surfaces with very slight curvatures due to rigid construction.
(d) Are not readily portable since special equipment and electricity are required for operation.
~` .
(e) Due to high cost and other factors such as the need for special training they cannot be offered as a do-it-yourself kit. ~ -Another type of marking apparatus uses chemical etching toaccompIish the marking of glass surfaces. Among companies that sell such kits is the J.C. Whitney & Company, PØ Box 8410, Chicago, IL 60680. These kiks are comprised of a stencil and etching cream usually containing hydrofluoric :,.j , ' .; . .

acid. This type of marking apparatus suffers from the following disadvantages:
(a) Involves the use of a highly toxic etching cream containing hydrofluoric acid which can cause extensive burns if skin contact occurs.
(b) The etching process releases harmful fluorine and hydrogen fluoride gases.
- (c) The resulting marks are often unclear or not well defined since the acid tends to leach under the stencil.
(d) The resulting engraving marks are often not very deep in the glass and therefore easier to obliterate or remove.
(e) Only glass surfaces can be marked and not surfaces made of other materials such as metal or plastic.
`

O~jects and Advantages Accordingly, several objects and advantages of the present invention are:
.~
(a) to provide an apparatus for engraving identification $ which is quite simple in construction and use, efficient, ~ time-saving, accurate and generally inexpensive to r manufacture and use.
~,,. , (b) to provide an engraving apparatus which requires no special training to operate and can be sold as a do-it-yourself kit so that consumers can engrave their own vehicle against theft and do not have to go to a garage to have it done.

Description-Figs. 1 to 4 A typical embodiment of the present invention is illustrated in Figures 1, 2, 3 and 4. In the preferred embodiment a stencil 9 (Figs 1 to 3) is comprised of a stencil body 10 made of one piece of flexible, durable plastic such as ~ -polyester. Stencil body 10 can also consist of any other material that can be repeatedly bent without fracturing and be able to withstand the mechanical friction of an engraving scribe 16 such as polyethylene, polypropylene, vinyl, nylon, various impregnated or laminated fibrous materials, various plasticized materials, etc. Stencil body 10 may also consist ~-~
,~,. ,,~ .
,~.~ .. .
~ . .
7 ,,1,~03`~
of metal sheeting made of, for example, brass, aluminum or other metals. Stencil body 10 must be flexible so that curved surfaces such as curved window surfaces on vehicles may also be engraved and is typically .3 to 4 mm in thickness.
Figures 1 to 3 show indicia apertures 12 in stencil body 10.
Indicia apertures 12 can be machined in stencil body 10 using for example a pantograph type engraving machine. Indicia apertures 12 correspond to the numbers and/or letters and/or symbols that make up the identification code for the vehicle or belonging.
Two pieces of self adhesive tape 14 (Fig 2) where both sides are coated with an adhesive mixture are affixed to the back of stencil body 10 above and below indicia apertures 12 and are folded over to the opposite or front side of the stencil shown in Fig 1. Folding the adhesive tape 14 in this fashion prevents the adhesive tape from easily separating from stencil body 10. Figure 3 shows an exploded view of stencil 9 showing adhesive tapes 14.
.
In some cases it has been found to be advantageous not to fold one or more of the extending portions of tape 14 over to ~`~ the opposite side of the stencil; but to leave it extended, -~ thereby forming a tab that is useful for removing and <-~ positioning stencil 9. This tab can also be covered with a ~, piece of tape or plastic foil so that the tab is not sticky ~ lo touch.
f~ i The adhesive mixture on adhesive tapes 14 is of a pressure sensitive type so that stencil 9 can be mounted and removed repeatedly such as when engraving numerous parts of a vehicle ` such as all the glass panes and perhaps other parts such as . the tire rims, motor etc.
.
~i, The engraving scribe 16 shown in Figs. 1 ~ 4 is of such a construction that the tip fits through indicia apertures 12 ;
.~ .
, ` 8 .~4~3~
, .
and makes physical contact with a surface to be engraved 18.
The tip of engraving scribe 16 typically consists of a solitary mounted diamond 20 (Fig. 4). However other hard materials such as tungsten carbide or corundum may also be used.
Operation-Fig 1 The manner of using this engraving apparatus is to first of all affix stencil 9 (Fig l) to surface to be engraved 18 and then insert the tip of engraving scribe 16 into indicia apertures 12 until it makes physical contact with the surface to be engraved 18 and with a light stroking action remove material from surface to be engraved 18. As a result surface to be engraved 18 will be engraved with the characters, numbers or symbols that correspond to indicia apertures 12.
Upon finishing, stencil 9 can be pulled off and reused to engrave numerous parts of the vehicle. It is envisioned that this apparatus can mark the same identification indicia upon each pane of glass of a vehicle in an unobtrusive spot. For example, on a four-door sedan there could be six identification marks, one being on the windshield, another on the rear window, and one on each of the panes of glass of the four doors. This identification code is typically filed along with information about the owner, such as his name, address and other pertinent information in a central registry so that if necessary the owner of that vehicle can be located such as when a stolen vehicle is recovered. Stencil 9 can either be included in the kit with a random code or made to ~-specifications supplied by the purchaser of the kit. For example the code can consist of the vehicle chassis number.
My engraving apparatus can also be used to mark other belongings such as cameras, computers and the like.

Figures 1 to 3 show indicia apertures 12 in stencil body 10.
Indicia apertures 12 can be machined in stencil body 10 using for example a pantograph type engraving machine. Indicia apertures 12 correspond to the numbers and/or letters and/or symbols that make up the identification code for the vehicle or belonging.
Two pieces of self adhesive tape 14 (Fig 2) where both sides are coated with an adhesive mixture are affixed to the back of stencil body 10 above and below indicia apertures 12 and are folded over to the opposite or front side of the stencil shown in Fig 1.
