To all whom it may concern.-

Be it known that I, JOHN BAYNES, a subject of the Queen of Great Britain, residing at Westchester, Westchester county, New York, have invented certain new and useful Improvements in the Method of Producing Ornamental Articles, of which the following is a specification.

My invention has for its object to facilitate the ornamentation of articles of irregular or unequal forms, upon the surfaces of which it is desired to duplicate any pattern; and my invention consists in coating such article with a resist and removing portions of the latter through the openings of a flexible stencil conforming in outline to a definite section of the article to be ornamented, and adapted to be successively applied in different positions and to fit closely against the irregular surface while the portions exposed through the stencil are being operated upon.

In the accompanying drawings, Figure 1 is a perspective view, and Fig. 2 is a plan view, illustrating a vase with an improved stencil applied thereto in carrying out my improved method of ornamentation. Fig. 3 is a plan view showing the mode in which the stencil is applied in ornamenting the surface of a plaque.

In the manufacture or ornamentation of articles of substantially circular cross section butof varying diameter, as spheres, globes, vases of different shapes, goblets, drinkingcups, &c., I have heretofore covered the face of the article with an acid resisting film, have then applied a flexible stencil to cover the parts not to be acted upon by the acid, and have removed the resist by means of a brush operating through the stencil, after which the article is etched or subjected to a sand-blast, or the exposed surface otherwise operated upon to produce the desired effect. This mode of operation involves the necess1ty,w1th such irregular-shaped articles, of using a special stencil for each article, corresponding in shape to the form of such article, and therefore involves considerable expense in the manufacture. To overcome these objections I construct the stencil in such shape as to correspond to a definite longitudinal section or division of the surface of the article, so that the stencil may be applied to operate upon one division and then shifted to another and then to another, and so on until the entire surface has been operated upon. Thus for the purpose of ornamenting a metallic vase A of the form show in the drawings, I construct a stencil-plate B, preferably of thin metal, as heavy tin-foil, corresponding in form to a definite division of the surface of the vase, for instance, to the exact form of onesixth or one-eighth of said surface, so that by applying the said plate six or eight times in different positions upon the vase it will be applied to the complete surface.

The vase to be ornamented is covered with a suitable resist, according to the character of the agent to be employed for operating upon the surface. If acid is to be used, I employ an acid resistas, for instance, a coating of asphaltand after the latter has dried upon the surface I coat the surface of the resist with a coating of soap or any suitable gum solution or other matter which will insure a temporary adhesion of the flexible metal stencil to the surface to which it is applied. The stencil-plate is cut in any suitable manner, according to the pattern to be produced, and is applied to the soaped surface and pressed down closely thereon, so as to adhere thereto. A brush charged with turpentine or other suitable solvent is then used to wash away such part of the resist as may be exposed through the openings in the stencil. After one section of the article has been operated upon in this way the stencil is removed and placed in another position upon the article, and the resist is then removed from this section, and soon until the entire surface has been operated upon. The vase is then subjected to the acid or other agent which operates upon the exposed surfaces, after which the remaining portions of the resist are removed to expose the surfaces which have not been operated upon. As a stencil made of rigid material would seldom fit close at the edges of its openings to the surface of the resist, and would, therefore, permit the solvent to flowbeneath the stencil, destroying the pattern, I use a plate of pliable, non-elastic, flexible material-such as tin-foil-which can be pressed down tight-1y against the surface, notwithstanding it is irregular, so as to afford no space for the entrace of the solvent beneath the metal. I do not, however, limit myself to the use of tin or metal, as in some instances paper stencils may be made of paper coated with shellac or otherwise stiffened and Water-proofed, or fine linen or other fabric properly coated may be employed. Neither is it always essential to use a solvent for removing the resist, as in some cases the material may be mechanically removed by the action of the brush or other tool.

I have referred to my improvement in'connection with a vase the outside of which is to be ornamented; but it will be evident that itmay be employed in connection with the ornamentation of articles of different forms and applied either to the external or internal surfaces, and also in the ornamentation of the production of ornamented articles, which consists in coating such articles with a resist and applying a pliable non-elastic stencilplate coinciding in outline with a definite section of the article successively to different portions thereof until it has been applied to the Whole surface then removing the portions of the resist from the articles through the stencil-plate, and then acting on the exposed parts by a suitable agent, and, finally, removing the resist, substantially as set forth.

2. The within-described process of ornamentin g articles of varying diameter, consisting in coating the article with a resist, applying thereto a pliable stencil corresponding in outline with a definite longitudinal section of the surface of the article, the Width of the stencil at any point being equal to the divis- In testimony whereof I- have signed. myname to this specification in the presence of two subscribing witnesses.
