''''''' uri UNITED STATES PATENT OFFICE.
OARL FREDERIOI, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF HIS RIGHT TO EDWARD B. GRANT, OF SAME PLACE.
IMPROVEMENT |`N ORNAMENTAL WlNDOW-GLASS.
Specification forming part of Letters Patent No. 141,782, dated August v12, 1873; application led February 21, 1873.
To all whom it may concern: a
Be it known that I, CARL FREDERIGI, of the city, county, and State of New York, have invented a new and useful Improvement in the Manufacture of Ornamental Panes of Glass 5 and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanyin g drawing forming part of this specication, in which drawing- Figure l represents a transverse section of this invention. Figs. 2 and 3 show plan views of the parts detached.
Similar letters indicate corresponding parts.
This invention consists in a pane of glass composed of two plates, which are placed one against the other, and each of which is stained or dashed on its inner surface, and also provided with ornaments produced in the same by the sand-blast process, or by etching, the ornaments in one plate being made to register to a certain degree with those in the other plate, in such a manner that, when the two plates are placed against each other, various beautiful effects can be produced, while at the same time the ornamented side of each plate is fully protected, and the pane can .be freely cleaned or washed without injuring the said ornamented sides. y
In the drawing, the letter A designates my pane of glass, which is composed of two plates, B G. Each of these plates is either stained or flashed on one side, and also provided with ornaments b or c, produced by the sand-blast process, or by etching, or in any other suitable manner. These ornaments penetrate beneath the staining color, or the colored layer of a flashed plate of glass, and the ornaments b are the reverse of the ornaments c, the former being sunk in where the latter are flush with the surface of the plate, and vice versa, or, in other words, the former being the negative of the latter, or vice versa. Some parts of the ornaments b, however, are the exact counterparts of the ornaments c.
By placing the two plates B O with their ornamented sides one against the other, a pane of glass is produced which gives an effect that cannot be obtained by a single pane. The colors of the two plates blend into each otherin such a manner that when the combined pane is held against the light many different shades are obtained, which cannot be produced by staining or flashing a single plate, and, furthermore, the ornaments of one plate form a relief for the ornaments of the other plate, and, according to the position given to the two plates in relation to each other, the effect produced will vary in many ways without changing the ornaments or the colors; and, furthermore, the ornamented surfaces of the two plates, being on the inner sides of said plates, are fully protected, and my pane can be washed and cleaned without danger of injuring said ornamental sides.
This invention is intended particularly for the purpose of multiplying the effect of flashed glass, which is manufactured only in a limited variety of colors, and by combining two plates in the manner above described this variety can be materially increased.
What I claim as new, and desire to secure by Letters Patent, is-
As a new article of manufacture, a pane of glass composed of two plates united, each of a different color, having etched or cut upon their inner sides similar designs that register with each other, the design on one plate being a cameo, c, and that on the other an intaglio, b, substantially as and for the purpose described.
