METHOD OF IMITATING STAlNED GLASS.

SPECIFICATION forming part of Letters Patent No. 340,485, dated April 2.0, 1886.

Application filed March 10, 1885. Serin-1 No. 152354'. (Specimens.) Patented in England October 11, 1884, No. 13,44'2.

To all whom, it may concern.-

Be it known that I, ALBERTA HARY FRAN- CES GASPAR, of London, England, a subject of the Queen of Great Britain, have invented certain new and useful Improvements in Imitation Stained Glass, of which the following is a specification, (for which I have obtained a patent in Great Britain, N o. 13,442, dated October 111884.)

My invention consists in applying to one or both surfaces of a continuous sheet of glass imitation leads, Whichare caused toadhere to the surface of the glass by the use of a suit- A able adhesive material, and in filling the spaces defined. by the imitation leads with adhesive 4coloring-matter, which closely and permanently adheres to the glass. The imitation-lead lilies are made in such shape as may be desired,and are applied to the glass in the shape in which they are originally made, or can be sprung or bent somewhat fromv their .original shape a't the time -of application to the glass.

lily invention further consists in the employment of a specially-prepared compound for application to the joints where the imitation leads meet one another to simulate the solder employed in genuine stained glass for strips.v

The imitationstained glass made by the. practice of my invention is applicable, so far as I am aware, to all the purposes to which genuine stained glass can be put, and will be i'ounddurable in use, and the brilliancy andv tone of the colors are lastinO- and if desired, sheets of glass decorated by my process may be employed for decorative purposes in Windowsashes in which ordinary glass has already been placed by cutting the sheet of decorated glass of such size as to tit snugly Within the sash against the ordinary glass, and the decorated sheet of glass may be fastened in the sash by small nails, little strips of wood, or in any other suitable manner.

To carry out my invention I- proceed as follows: I first select the desired design which I intend to reproduce upon the glass, or, having drawn a design on a piece of paper, I lay.

5o the` glass cut to the proper size upon the paper These imitation leads are made from card or paste board or other like material, and are cut out and pressed by any suitable device or ma chine in such manner as to make them slightly convex on their upper surface and slightly concave on their under surface; and the con- 6o Vex surface .is coated with metallic paper, or other metallic coa-ting` the better to simulate the genuine leads. It is obvious that if economy is not specially desired the imitation leads may be made from solid metal, either lead or any other suitable metal or composition of metal, and may bc cast therefrom, or cut, stamped, pressed, or otherwise formed to the desired shape and slze. Sheetdead 1s very suitable for this purpose, and the cementing material used to attach these metallic imitation leads to the glass may he any substance suitable for that purpose. As stated, these leads may be cut out by dies in predetermined shapes, or may be made in straight, 7 5

zigzag, irregular, or curved strips, which may be sprung or bent somewhat from their original shape when applied to the glass, so as to :follow the desired design exactly.

Moreover, pressure may be employed in at- 8o taehing them to the surface of the glass to produce close attachment by means ofthe adhesive material, if desired; and, if desired, the leads may be produced in the exact conliguration or outline of the design by cutting the same out from a sheet of card-board or paste-v board which is -coated with metallic paper or, otherwise coated. If produced as last stated, however, the leads lack the convex outer surface and concave under surface, which greatly 9o add to their efficiency. I do not limit myself, however, to the concave-convex shape. rIlhey may be dat, if preferred.

The metallic-like outer surface may be given to the leads in any known manner, and thus they will simulate any desired metal. Lead and brass are most preferred by me, because they are most frequently employed in genuine stained glass; but other metals may be simulated in like manner.

Any suitable adhesive roc or cementing material may be used to adhere the leads to the surface of the glass; but I prefer for this purpose thick white lead mixed with strong driers, and preferably colored to resemble the color of the metallic surface of the leads. For outside use it is especially de sirablc that the adhesive substance should be such as will not be affected by wet or. cold and heat. The white lead and driersare very suitable for this purpose.

"When the leads forming the whole of the pattern or design have been applied to the glass and dried thereon, (care having been taken to make all the joints in the leading fit closely and well,) I next proceed to imitate the metallic solder-ings. To do this I mix a small quantity of metallic powder of the requisite color to a thick creamy consistency with spirit varnish. (usually copal gum dissolved in alcohnl,) and drop sufficient of this paste from a small brush on all the joints in the work to entirely hide them. This substance settles and hardens very quickly, but while it is still damp Il filled with bright bronze-powder of the rcqui site hue, sufficient of this adhering'tc give am exact resemblance of the appearance appertaining to'real Ametal soldcrings. XVhcufthis part of the work is finished, itis advisable to leave the glass for some hours tcldry thoroughl y before the application of thejeolors.

The liquid colors I usually empley are those generally used for lacquer work on tim-being anilines and varnish colors, which are translucent and in some instances transparent nd rapid to dry being mixed with alcohol. Any kind of adhesive coloring-matter would', howi. ever, answer for the purpose, and where subjected to strong lights Iprefer the vegetable colors as being most permanent. To apply them to the glass on the reverse side to which4 the leads arc iixedor on the. saine. side as preferred, I either pouror drop from brush or stick a few drops of color on the upper part of the space I desire to cover, (the plate of glass being somewhat inclined.) which space is of course denoted by the outlines of the metallic pattern on the glass,and allowing the color to spread over the space smoothly,as sisting its ilow with the brush or sticleif necessary. In this way I get a perfectly smooth even surface without any brush-marks or other imperfection. In fact, if properly executed, the color appears to be on the glass itself. The color dries rapidly, generally becoming cloudy for a few moments before resuming its permanentbrilliant appearance, and until this clouding or partial fixing of the color has taken place I am careful not to disturb the glass. The glass should preferably be in a horizontal position while the colors are drying.

When all the colors have been applied and are dry, I generally apply to them acoating of thin mastic turpentine varnish to more thoroughly protect them from the atmosphere;

- but this is not a necessity, however, and not ightl y pass over it a dry brush,r

advisable where very transparent white glass is used, although it can be advantageously adopted Where cathedral, roughened, opaque, owered, embossed, muffled, or crackled varieties of glass are employed.

The imitation leads may be placed onjboth sides ofthe glass,ifdesired,ofconrse coinciding in location on both sides, and this will be desirable where both sides of the glass will be exposed to view. The color mayA also' be applied to both sides, but this is unnecessary. If

the color be applied Ato the side on which the leads have been attached,they will greatly aid in such applicatiomsince they will act as little dams and prevent the spreading or running of the colors together. Care must be observed,' however, not to employ too much color. The best results are attained by a. simple coating therepf, such as will result by flowing the colorfover the glass, as above described.

"llhe leads may be applied either before or after the colors have beeu'applied; but I pr'efdr to apply them before. When thus applied,

,fliey will appear as seen on the upper sidey of the plate shown in Figure 1, Aand when applied after the color has` been applied they will cover the line between the colors, as seen on. the under side of the plate shown in Fig. 1.

Any excess of soldering material or adhesive:

materiall (provided the white lead and driers have been employed as the adhesive material) may be readily removed by scraping with a knife, or if not too much solidified with turpentine; and any excess of coloring-matter may be removed with meth ylated spirits of wine.

To still further vary my designs and give the .effect of mosaics of frosted glass beinginserted,

sometimes grind portions of the pattern into 6; acity by rubbing them well with a glass mulleislipped in damp sand until the appearance of rpsted or unpolished glass is obtained. A scond sheet of glass may, if desired, in very xposed positions be placed upon thel sheet doorated, as stated, the edges being united with any suitable cement or metallic, wooden, orother binder for the edges, preferably employing some sort of cement, however, between the edges of the glasses to prevent dust and moisture from getting in between them, which would dull or obscure the brilliancy of the colors A coating of transparent weather-proof varnish may be applied over the entire decorated surface of the glass, including the leads, il' desired. This will still further protect the sann,l and add to its durability.

In the accompanying drawings the glass, leads, Ste., are enlarged the better to illustrate the invention. l y

The coating of varnish is not illustrated, since -it would simply be a very fine line over all the u ent, sealing-wax, beeswax, Burgundy pitch,

and the like materials, which are applied in a plastic state and allowed to dry and harden on the glass, and the spaces between these imitation-lead lines thuslformed being then filled with coloring materials, and I do not lay claim thereto, my invention, so far as the leads are concerned, consisting in first making the leadsas separate and completed structures and then adhering them, as such, to the glass by the employment of adhesive substance between them and the glass. By this means my glass can be made by any one by simply purchasing the leads, the cement, and the coloring materials, and without any apparatus or special skillwhich is requisite for the manu'- facture of the leading material and its application to the glass by the otherprocesses stated.

Having described my invention, I claim- 1. As a new article of manufacture,imitation stained glass consisting of a sheetof glass upon the surface whereof are adhered cardboard or pasteboard imitation leads, the spaces between the leads on either side of the glass being lled with adhesive coloring-matter, substantially as and for the purposes set forth.

2. As a new manufacture, imitation stained glass consisting of a sheet of glass upon the surface whereof are adhered card-board or pasteboard imitation leads and adhesive co1- oring-matter applied to the glass coinciding with the leads, and a protecting coat of weatherproof Varnish applied to the surface of the coloring-matter, substantially as and for the purposes set forth.

3. The herein described concavo convex imitation lead for use in the manufacture of imitation ystained glass.
