IMPROVEMENT IN GLASS PANELS.

Specification forming part of Letters Patent No. 178,904, dated J line 20, 1876; application filed April 1,1876.

To all whom it may concern Be it known that I, JAMES BUDD, of the city, county, and State of New York, have invented certain new and useful Improvements in Panels for Railroad-Cars, of which the following is a specification:

This invention relates to the construction of the exterior panels of railroadcars, and it is particularly designed for that class known as palace, parlor, and sleeping cars. It consists in dispensing with the usual varnished hard-wood panels, and substituting therefor glass panels suitably ornamented on the interior surface, in the manner as will be hereinafter fully pointed out and claimed.

In the drawings, Figure 1 represents a side elevation of an ordinary passenger car in which is fully embodied my invention and Fig. 2 represents an enlarged cross-section of a glass car-panel, showing the application of the ornamenting material.

The present method of finishing the exterior panels of the expensive classes of railroadcars known as palace, parlor, and sleep;

ing cars, by means of hard-wood panels which are highly polished and varnished, has many difficulties, the obviating of which is a great desideratum. It is desirable to A have them always present a new and bright appearance, and in the process of cleaning the exterior coating of varnish is quickly dulled and worn off, exposing the wood, which quickly deteriorates by the action of the elements, thus necessitating the frequent withdrawal of the car from duty for the purpose of revarnishin g and repairs.

In carrying out my invention I dispense with the exterior wood paneling of the car, and insert in the frames or moldings glass panels, which are ornamented on their rear surface with such stripes, figures, designs, or imitations of wood as may be desired.

In the process of ornamentation, the panel of glass is first thoroughly cleaned. It is then coated with white shellac varnish, which is flowed on the-surface, so as to insure an even coating. When dry, the ornamental stripes or colored figures or designs are painted upon the shellaced surface in oil-colors, as fancy or taste may call for. These stripes and figures, when dry, are then covered with shellac the glass with a brush, in the ordinary man-" When dry, this final coat of color is V ner. entirely covered with a coating of thick shellac varnish, the alcohol being evaporated therefrom, so as to leave it in a thick pasty condition, which is immediately coated with plaster-of-paris. This maybe applied or sifted on by any means desired, so that it is evenly deposited. The shellac at once absorbs the 'plaster-ofparis, the combination of the two drying quickly and forming an impervious coating.

In Fig. 2 of the drawings the applications of these various coatings to the glass are shown, thesame being drawn on an enlarged scale, for the purpose of plainly indicating each stage of the process and application. A

represents the glass; B, the first coating of 1 shellac varnish; a, the ornamental striping figures, or designs; b, the coating of shellac varnish applied over them for the purpose of making their rear surface identical with the previously-coated surface of the glass. D represents the final or body coating of plain color, and F the final or finishing coating of impervious matter.

The object of first coating the glass with shellac varnish is to provide a suitable base upon which to lay the oil-colors, which shall prevent the paint from blistering or peeling off by the action of the sun, or from other exposure, which would occur were the oil-colors laid directly upon the glass surface. The stripes and ornamental designs in oil-colors, after being laid, are also covered with shellac, so as to make the entire surface alike for the application of the final coat of coloring. The

finishing coating of shellac and plaster-ofparis is for the purpose of preventing any dampness from reaching the colors in case any water should get in between the glass panel and the wood backing forming the interior of the car. v

I make no changes in the general construction of the car, merely omitting the exterior wood panels.

The glass panels'may be set into a bed of any elastic material attached to the moldings which will give tight but elastic joints, and

also provide for any variations caused by ex pansion and contraction.

It is plainly apparent that a car provided with these glass panels, ornamented as deapplying the design thereon in oil -colors third, again coating the whole with shellac; fourth, applying a'coat of coloring, and, finally, backing the whole with thick shellac val"- nish and plaster-of-paris, substantially as and for the purposes set forth,

shellac varnish, a design in oil-color, asecond coat of shellac, acoat of coloring, and a backing of thick shellac varnishpand plaster-ofparis, substantially as and for the purposes set forth. 7
