coating. The soluble portions of the coating To all whom it may concern:

Be it known that I, J OHN BAYNES, a subject of the Queen of. Great Britain, residing at Westchester, in the county of Westchester f and State of New York, haveinvented certain new and useful Improvements in theManufacture of Articles Having Faces Ornamented by Metallic Patterns, 6f which the following is a -specifioation. I9.

. My invention relates to the process of ornamentingvases or similararticles, substan-- tially as hereinafter set forth.- 4 In the drawings, Figure 1' is an elevation of a vase in part section and perspective view of the patternrplate, illustrating my improvemcnt. Fig. 2 is a side view of a vase ornamented in accordance .with my invention.

Figs. 3 an d 4 illustrate modifications of myprocess, and Fig. 5 illustrates an article composed entirely of metal produced by my process.

For the purpose of describing myinvention I shall refer to the manufacture of ornamen. tal vases; but it will be understood that the invention may be employed in the manufacture of various articles or parts of articles Where a metal or alloy capable of being deposited electrically may be employed either desired extent.

for the purpose of forming the body of the article or part thereof or of forming an ornamental facing or partial facing thereto.v

If it is desired to use. the deposited metal as .an ovtrlayer uponavase of pottery or similar material, I first properly prepare the surface of the vase A, so.that -it will receive a deposit of metal by electricity from a suitable solution by coating it with a base or foundation film of composition, such as wax and plumbago, and I'then place it in such solution and apply the deposit in a manner too well known to need description, the said deposit constitntin g a continuous overlying film 2 of athickness which may be "aried to any Upon the surface of film 2 is then applied a coating of any suitable resist sensitive to light, the said coating being indicatedbydotted lines 3, Fig. 1 of the draw- Se'riaPNo. 223,783- (No model.)

are now dissolved, leaving thepattern traced by the insoluble portions,-and' the article is then immersed in an acid bath, whlch will" etch into or through the electro-deposit film wherever the same may be exposed, after which the article is removed and the resist '15 scraped or otherwise removed, leaving 'npon ,the surface of the article ansornamental pata stencil 5, applied thereto, the exposed portions of the resist being removed by abrasionby means of a brush or by the action of a solvent, as turpentine or naphtha, carried by a A second coating of a difk brush or sponge.

ferent metal may be applied upon or in any desired position in relation to the pattern formed by the first coating to secure a more elaborate ornamentation of'the article. This second pattern isdeposited by first coating,

the articlehavingthe firsns pattern thereon with a film of wax and plumbago, electro-de-' positing. asecond base or" foundation film of another metal over the entire surface, .and then etching through thesecon'd film of metal in the same manner as before. If, for instance, the vase A, Fig. 2, be a porous vase, upon which the flower pattern has been deposited of one metal-say silver-the second pattern or ornamentation, representing fiylng birds or insects,'is deposited in like manner in gold or nickel. v

. ,VVhile I may use any of the resists and solvents known to those skilled in the art, Ihave found a resist-such as is described in my consistingof, say, nin ety parts of asphaltum,

eighty parts of oil of turpentine, andten parts -gum-copal, and the parts unaffected by light maybe removed by applying a solvent, as turpentine, in any usual manner; The time of exposure to light, of course, will depend upon the composition used, the condition of the light, and the character of thework to be done, and may vary from two hours, more or less. The body of the article may be made entirely of the electro-deposited metal by first forming a pattern of soluble or friable mate- I rial'as, for instance, plaster-of-paris 6co.at-

ing it with plumbago, depositing aheavy film of metal 7-say copper-thereon, then coating the latter with a resist 8, forming thepattern on the resist, and etching through. the same and completely through the body metal (see Fig. 5) in the same manner as hereinbefore described, the model being then broken or re moved by a suitable solvent, leaving a hollow perforated shell. The first base or foundationcoating or film of wax and plumbagois also removed by dissolving it in a suitable solution or otherwise, leaving the electro-deposited coating surrounding the body of the vase or other vessel, but independent of it.-

It wilHoe evident that my improved methed of ornamenting articles vmay be applied in connection with various metals capable of electro-deposit inthe manufacture of various different articles or, parts of articles, like tiles and similar articles. N

- Without limiting myself to the precise manipu-lations herein set forth or to the use of the special materials specified. I claim 1.- The process of ,orname'nting vases or similar articles having ornamental metal patterns upon their faces, which consists in first j coating the; articles with'a film of wax. and plumbago, then coating the entire face of the body' portion of the article with a film of the ornamentin g metal by electro-deposition,then applying a coating of resist susceptible tothe action-of the light, then acting upon the resis't by rays of light through a pattern-plate,

- then removing the soluble portions of the resist and etching through the orn amenting metal at the exposed parts, then removing the coating of resist, subjecting it to the rays of light through a pattern-plate and. removing the soluble portions thereof, then etching through the ornamenting metal at the exposed parts then applying a second foundation-coating of wax or plpmbago, then appplying a second metallic coating of a different metal upon said face, and repeating the operations to complete the ornamentation, and finally removing the base-coatings, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
