Serial n'ul zadoas.

Tliis invention relates to the method of producing patterns. or designs by stencillng over irregular surfaces and more particularly to the method of producing a stripe design 011 the spokes of automobile Wheels:

Heretofore the striping of. automobile Wheels has been by hand and stencils have been'found' inipracticaldue to the irregular tofsecure'a resilient stencil under pressure withits edges in contact with an irregular surface so that the design maybe sprayed thru the stencil. '1

Theinvention will be more clearly under 2 stood by reference to the following description taken in connection with the accompany ing drawings in which:

Fig. Tie a sectional View thru an automobile-wheel and asupport therefor show i mg a method of securing the stencil thereon. Fig. 2 is a plan view ofthe stencil. Fig. 3is a sectionalview on line 3+3 of Filr. 4 is a .fragnientairyplan iew of a portion of the stencilillustra ting the movement of the edges around the opening. Fig. 5is a sectional View on line 5-5 of Fig. 4.

Referring particularly to Fig, 1 of the drawings, a pedestal 1 0 liasbeen shown havingawork supporting member 12 pivoted atits upperfl end. Extending'thru theWork supporting member 12 is a reciprocal locking member 14: and. upon Which I have shown a tapered sleeve 16. adapted to receive the hub 18 of. anjautomobile WlIGBlQD. Atone end of the member 14:Il1 ave provideda piston 22 which fits angair chamber 24 in the support 1 12. Pipes 26 communicate With the chainberQl: at oppositesides of the piston 22 so thatby positioningavalve, not shown, one is adapted to supply an'air pressure and the other receives the exhausted air at the opposits side of the piston. The'pistonmay be 60 moved in either direction by causing an air pressure be applied thru either pipe the other acting as theexhaust conduit.

The Wheel hub,18.is placed on the tapered sleeve 16 andthe stencil placedover the outer surfaceof the Wheel andcohnected to TO F E the member 14 in such a manner that its The end ofthe member 14: opposite the piston 22 is provided With a groove 28 adapted to receive apivotedhook 30 on the stencil. By applyingpressure at one side of the piston 22; the stencil may be moved away from the Wheel and by applying a pressure at the opposite side of the piston the stencil is resiliently held in contact with the'irregular Wheel surface.

The stencil comprises a hub p0rtion32 and a plate portion 34. The hub portion is adapted to fitover the member 14: and the hook 30.is pivoted on its outer and; A plu rality ofv springfingers 36and 38 are. secured to the hub member. The springs '36 are se cured to the plate portion 34:by projections 40 received in slots 42 in the springs 36. .A

head portion 4:4: holds the plate 343011 the springs 36. The slip connection has been provided to permit the saline tension on each portion ofthe plate. a

. The figure to be stenciledor the spoke stripes are cut in the plate 34: providing openings ldthru'vvhich the design is sprayed. In.

forming a stencilrfor the particular design illustrated, V shaped portions 48 are formed andthe springs 38 engage these resiliently movement to the left holds the stencil tightly againstthevvheel and holds the latter onthe tapered sleeve 16:

forcing them against the irregular surface of the spokes. The V shaped portions are bent slightly belovv the normal contacting surface so that \vhen they engage and. disengage the Wheel surface a wiping effect is obtained. The portions 50 between each of V the openings 46 are provided Withdepressed portions 52uaround the edge of the openings so that they slightly slideyvhen' making contact. It is this feature that makes stenciling irregular surfaces possible because the edges ofthestencil are slightly-drawn away from the Y paint before it p is removed from the work thus preventing blurring or running of the paint.

In order that the stencil may be as flexible as possible the plate 34 is made as a small as possible and in order to cover the entire wheel a segmental flange is secured to the outer ieriphery of the plate. This flange is made up of a plurality of flanged members 54 shown rivetedto the plate 34 as at 56.

The stencil is positioned on the wheel angularly by a pair of resilient clips 58 which engage one of the spokes.

It will be understood that various changes may be made in the construction and arrangement of parts without departing from the spirit of my invention, that the stencil may be used for applying various designs to parts other than automobile wheels, and that it is not my intention to limit its scope other than by the terms of the appended claims.

hat I claim is:

1. The method of striping spoked wheels which consists in applying a resilient stencil to the surface thereof, forcing the stencil against said surface to cause the edges of the openings in said stencil to slide on said s rface, and spraying paint thru said openin 2. The method of forming designs on 11'- regular surfaces which consists in applying a resilient stencil to said surface, pressing the stencil against said surface to cause the edges of the openings in said stencil to slide on said surface, and applying paint to said surface thru the openings in said stencil.

3. The method of stripping wheels which consists in applying a resilient stencil to the surface thereof, pressing the stencil against said surface at points on portions between the openings of said stencil whereby the edges of the opening slide on the wheel, and applying paint to said surface thru the openings in said stencil.

4. A stencil of the class described comprising a central hub member, a plate spaced from said hub member and provided with openings corresponding in shape to the design desired, resilient flanges at the ed as of the openings, and spring members secured to said hub adapted to frictionally engage portions of said plate, certain of said spring members adapted to connect said plate to said hub.

5. A stencil of the class described comprising a supporting member, a plate spaced fro n said supporting member and provided with openings, spring members secured to said supporting member adapted to engage the portions of said plate between said openings and adapted to form a connection bet-ween said plate and said support, and depressed portions in said plate around the openings in said plate.

6. A stencil of the class described comprising a supporting member, a plate resiliently connected to said supporting member and provided with openings thru which paint may be applied, and resilient depressed portions on said plate around the edge of said openings.

7. The method of striping spoke'd wheels which consists in applying a resilient stencil to the surface thereof, forcing the stencil against said surface to cause the edges of the openings in said stencil to slide on said surface, and spraying paint thru said openings, then sliding the stencil on the surface away from the opening.

8. The method of forming designs on irregular surfaccs which consists in applying a resilient stencil to said surface, pressing the stencil against said surface to cause the edges of the openings in said stencil to slide on said surface, and applying paint to said surface thru the openings in said stencil, then sliding the stencil on the surface away from the opening.

9. The method of applying a stencil marking to a surface which comprises placing a flexible stencil on the surface, pressing the flexible stencil to thereby cause the edges of the openings to slide toward the portion of the surface to be painten, and removing the pressure after painting to permit the edges to slide awayfrom the painted surface prior to removing the stencil from the work.

10. The method of applying a stencil marking to a surface which comprises sliding the edges of the openings in the stencil to ward the surfaces to be marked, applying a coloring through the openings, and sliding the edges of the openings away from the mark surface prior to removing the stencil from the work.

11. A stencil comprising a body portion having openings through which paint may be applied, the edges around the openings being movable in a plane parallel to the plane of said body portion.

12. A stencil comprising a body portion having openin through which paint may be applied, the edges around the openings being normally out of the plane of said body portion and yieldable to be moved under pressure into the plane of said body portion.

13. A stencil comprising a body portion having openings through which paint may be applied, resilient means normally forcing the edges around the openings out of the plane of said body portion and yielding to permit the edges to be moved into the plane of said body portion when the stencil is applied to the work.
