SPECIFICATION formingpart of Letters Patent N 0. 625,463, dated May 23,

Application filed June 1, 1898. Serial No. 882,254. (No model.)

To all whmrt it may concern:

,Belif known that we, THEOPHIL PFISTER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, and EMIL BARTHELS, a subject of the/ Emperor of Germany, residing at London, England, have invented an Improvement in Ornamental Panels for Windows, 550., of which the following is a specification.

i'Vindow-glass and transparent panels have heretofore been made in which strips of metal have been affixed to the surface of glass and loose materials, such as glass in a broken con dition or other granular materials, have been introduced between the strips of metal and caused to adhere by fish-glue and bichromate of potash, as set forth in Letters Patent No. 587,225, granted July27, 1898, to A. Navarein. Ornamental work of this character has nec essarily been covered by a sheet of glass in order to prevent the deleterious effects of moisture and to prevent. the surface of the v glass and ornamental work becoming soiled,

because such surface was not adapted to be ing washed or-cleaned, and if this ornamen tal work is at the back of a glass the beauty of the design is often interfered with by the light'that is reflected from the surface of the glass.

The present invention, as distinguished from ornamental transparent or translucent panels that have heretofore been made, consists in so forming the ornamental work upon the plate of glass or other material as to render it unnecessary to use a second plate of glass for inclosing the same, because by the present improvement the ornamental work is rendered waterproof and adapted to being washed or otherwise cleaned to maintain the brilliahcy of the panel without any injury to the ornamental work.

vIn carrying out the present invention we take a plate of glass or other material and lay the same upon paper or other material having upon it the pattern or design to be produced, or we mark out the pattern in any desired manner, and we afiix to the surface of the plate narrow strips of metal cut out or bent to conform to the outline of the ornamental work, and these strips or pieces of I metal are caused to adhere directly to the surface by a suitable cement, and we preferably use a Waterproof varnish, such as a quickdrying furniture-varnish, although glueor other adhesive material might be employed forthis purpose, as the after preparation preventsthe strips or pieces of metal becoming loose should the glue, be moistened or absorbed. tations have been applied and afiixed to the surface of the glass we place into the spaces thus formed short sections of prismatic glass or pieces similar to beads without perforations or suitable pieces of other material, and We arrange these with reference to the desired colors and to the artistic effects to be prod need and fill in the spaces between the strips of metal forming the outlines of the pattern more or less closely with such small transparent, translucent, or otherpieces. After the patterns or the desired portions of the patterns have been thus produced upon the glass we pour upon the pieces of glass or other matcrials-a strongly-adhesiveand transparent or nearly-transparent waterproof varnish of any suitable character, and we find for this purpose that French varnish slightly diluted with alcohol is generally preferable, and the partitions or strips of metal form dams to retain the liquid varnish thus poured upon the pieces of material, so that such varnish does not necessarily spread u ponany of the plain portions of the glass, and this varnish is allowed to set or dry, so as to hold the pieces of mineral material firmly together and to the glass and also to hold the strips or divisions to the smallpieces of mineral material and at the same time to firmly aliix these strips to the surface of the glass. By this manner the pieces of transparent or translucent materials are firmly affixed to the glass and a highly-artistic effect is produced by transmitted light, especially so where the varnish that is made use of is sub stantially colorless; but, if desired, transpar+ ent coloring material may be added to the var nish, as may be required for the artistic effeet that is to be produced.-

In some instances glue or other adhesive material'may be poured over the pieces of glass or other material as a primary fasten- After the outlines of the ornai'nening of such pieces to the plate of glass or other materiaL-and then the adhesive waterproof varnisl is added to form the finished surface that is adapted to resist the action of mois- 5 ture, especially in Washing and cleaning such surface.

The varnish in most cases increases the brilliancy of the transparent pieces of matei rial. The ornaments being in relief and covered by a waterproof varnish are clearly visible and aregnotobscured by reflected light,

as they are Wliol a plate of glass intervenes.

While this improvement is especially intended for windows and transparent panels, the same may be applied on wall or ceiling decorations, and where the ornamentation is to be in relief the outlining and preparation heretofore described will be followed, it be ing immaterialwhether the foundation plate or surface upon which the strips and the intermediate ornamentations are applied is of glass or'other material; but where the surface of the wall, ceiling, or panel is to be smooth the fiat surface of the glass is to be outward and the ornaments upon the surface will be at the back and embedded in plaster of diiferent color where desired; but the ornamentation prepared as aforesaid may be so fully filled in with a waterproof adhesive varnish as to present a smooth polished surface that can be part of the surface of the wall or ceiling, and especially where the plate prepared as aforesaid is not to transmit light. through it the small pieces of material upon the surface may be more or less opaque and of any desired color or gilded, having special reference to the artistic elfect to be produced.

In "the drawings, Figure 1 illustrates a dea section, of the panel in sign, and Fig. 2 larger size.

A represents a plate of glass or other material, to which the metal strips 13 are attached to form the pattern, and'the pieces of glass or other materials are shown as attached at C, with the waterproof adhesive varnish forming the surface to the ornamental work.

WVe claim as our invention- The ornamental work upon a plate of glass or similar material composed of strips forming the outlines of the design or ornamentation, and small intermediate pieces of glass or similar material, and a waterproof adhesive varnish for holding the pieces of material to the backing of sion-strips, substantially as set forth.

Signed by us this 16th day of May, 1898.
