vention to provide a painting shield or mask inv which provision is Lmade to cause intimate contact between the edges of the opening-cuts through the shield and the surface to. be

`1 5 painted'A so that` no paint will run or beV sprayed under thesefedges `to fog or disgure the pattern applied tothe painted surface', A

Another object of the inventionconsists y in the provisionvof means for accuratelypoi. sitioning and holding the shield in position whereby thepattern applied `through the shield is definitely located VAin respect to the boundaries of the surface on which` it is to be applied. m-

An important feature of the invention consists in the arrangementof a painting shield in ldished formation with a re-entrant bottoir'i portion'curved substantially on the sur facepofa cylinder and having a patternper-V 3o forated therein wherebyv flexing of the whole shield will tendto increase the radius ofV cuvvatureof the bottom portionto applypres-V sure to the edgesof thepattern openings and insure a tight fit of theshield against the raised surface on'whicha design is Vto be applied.

Another feature ofhtheinvention consists]V in providing a painting shield `or Vmask with *Other and further' features and objects of the invention will be more apparentto those accompanying drawingsand following speciiicatiOn, wherein is disclosed a single eXem'- plary ver'nbvodiment'of the invention with vthe r understanding, j'however, that suchf changes i lo may be made therein as fall within the scope provide a novel and improved paint- Y v v y c 1 z -l l showing the devioegapplied to a moulding- More particularly it isanV object of the in- `onthe, pyroxylin lwears it: off: "There vhasV already been ,developed` a suitable striping y for finishin'gfthe ends'of the stripes or for apof pyroxylinpaint bygpmyng skilled in the art upon the .consideration of the `lowtlie wiiidowsf'butfwith vslight variations, `it "is susceptible -cto numerous iother uses and' fi'oin the spirit of the invention,

` VReferring particularlyto Figures 1 and `3, Y,

Y there is shown at lOthe side of avehicle body 5 having either formed integral therewith'or Y surface ofthe moulding'which has-already received its maincoat of iinish.` The pattern here shownv is intended to form the finish i iY at the end of the moulding, fortwo parallelv 'stripes and so Vthe cutout includesportions 15 forming the beginning of'suchstripes..

' zo #The masker stencil is Vformedfrom thin,V

- springy sheetv metal such as shlimstock, as,

"for'instance, steel about .O08 inch thick.. AQ

lsheet 16 of this metal is `cut to the-proper f size,- lpreferably rectangularfand the corners have .triangles removed therefrom so tha-t'th'e l Y yperipheral portions ofthe rectangularsheet maybe bent upward untilthes'idelof the cut- Vouts meet as Vat l'fwh'ere they are secured tox Y l gether'by solderingV or weldingfto form the",

V mask into a dish-shaped device as clearlyjseen in'fFigureQ. T -hisdishing has two functions.

First, it Vmaterially strengthens'the shield and f gives YitV added rigidity, and second, [it pro- Y lvidesa loweredgewhich is substantially re-iv Simoved from thesurfaceoflthebody so that a and .dripping paint will r'not Afall onthis finished surface. Y Here it should be remarked Y that the stencil is customarily used on a sub-V l n stantially vertical surface asyshownzinFig;3.` 40@` The surface' of the bead 11 on which the pattern isto be applied; is substantially'cylindrical andin order that'the stencil'v may be i accommodated to this 'surface7 its bottom, in`

' the area indicated by the reference charq /facter118isformed witha re-entrant portion bestl kseen in Figs. 2 and 3, which has vthe-v contour of a'sector of a cylinderlof` a radius .substantially the same asthat of the outer surfaceofthe bead.

that of fillister screws. Th'efstemsof the rivets pass through-holes in the shield and the inner ends. are peened over, vas at 21to" retain them in position. Tol'ocate the shield Y 7V 0 i in respect to the end of the bead a large loeating button 22-'is provided, secured in position inthe same mannerfas the buttons 2O and having in its side the notch 23 which receives the end ,of the 4bead andlimits the movement of the shiel'dflongitudinally of the bead.

In use kthe operator grasps the upper'vand lower edges of the shieldbetween the thumb and ngers ofY one Vhand and pressesr the turned-up edges 24 slightly together iaslseen inthe dotted line Vpositionof Fig. 3.
