ORNAMENTALLY-ENGRAVED METAL Application filed June 2,

To all whom it may concern:

Be it known that I, EDWARD J. GULIOK, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Ornamentally-Engraved Metals and Methods of Producing Same, of which the following is a specification.

This invention relates to the ornamentation of metal surfaces by the art of engraving. While primarily intended for use in the ornamentation of metallic wind musical instruments, such, for instance, as saxophones, and the like, it is capable of more general application.

The invention proceeds upon the principle of applying to the surface of the metal object to be ornamented, one or more platings, layers, coatings, or films of material having a color or appearance in such contrast with that of the metal of which the body of the object is constructed, that designs composed of dots, lines, or surfaces of contrasting color or appearance may be produced by cutting through one or more exterior strata and exposing the metal of the body or the material of an inner stratum.

pon completion of the design, the entire surface, including the definition of the design as well as the ground surrounding the same, is surfaced with a transparent sizing or finish so as to maintain the natural colors unimpaired; and prior to the application of this finishing surface any desired portions of the design or of the ground work may be treated with pigment or coloring to further develop contrast.

In order that th invention may be fully understood, one method of realizing same is disclosed in the accompanying drawings, in which- Figure 1 is a front elevation of a portion of a metal wind musical instrument treated in accordance with the invention to develop a design thereon; and

Figure 2 is a section through the metal wall of the object shown in Figure 1 taken on the line 2" x of Figure 1, and drawn on a greatly magnified scale.

1 represents a thin metal wall to be ornamented, for instance, sheet brass, 2 is a metallic plating, for instance, silver and AND IvIETEGD Q1" PR-QDUGING 311MB.

therefore contrasting in color with the metal 1, the same being applied to said wall by any approved method such, for instance, as electroplating. 3 represents a stratum or layer or lacquer applied to the plating 2 and embodying in its composition pigment or coloring matter that contrasts in appearance with both the metal of the wall 1 and the plating 2. 4: represents a transparent sizing or finish that is applied over the surface after the engraving is completed; and 5 represents pigment or coloring matter of still another contrasting color or appearance that may be applied to any of the elements of the design, for instance, flower elements, to lend further character to the design. lhe pigment 5 will be applied preferably before the transparent sizing or finish 4.

As will be seen upon reference to Figure 2, the design can be made up of a ground work having the color characteristic af-. forded by the surface of the lacquer 3, the channels, such as shown at 6, which are characterized by the combined effect of the color of the lacquer 8 along the sides of the channels, and by the color of the metal plating 2 which has been uncovered at the bottoms of the channels; also channels such as 7, the appearance of which is characterized along the sides of the channels by the color of the lacquer 3 and that of the metal plating 2, and at the bottoms of the channels by the color of the metal 1. Similarly, the more extensive recess 8 will be characterized by the color of the body metal 1 merging into that of the plating 2 and that of the lacquer 3.

The design may be further variegated by applying pigment, such as 5, over some of the petals of the flower form 5.

From the foregoing it will be seen that a metal plate prepared as described can be very highly ornamented by simply cutting through, by any of the processes of etching, engraving, sand-blasting, etc., until dots, lines, grooves, channels, or other recesses are developed with the desired coloring efi'ect.

As a suitable lacquer'to develop the coating over the electrically deposited metal plating, I prefer to use known commercial lacquers, consisting of hard drying resinous body with fusel oil, alcohol, etc. as a vehicle.

For the outer transparent finishing coat I prefer to use the finishing material commercially known as izen.

I claim:

The method of ornamenting metal, which consists in applying to the surface of the metal, platings, coatings, filins or the like, to produce a composite material having strata of contrasting appearance, and then cutting through one or more strata of the resuitant piece to disclose under strata of the composite material on lines conforming to the ornamentation to he produced; the resultant surfaces and cuts being finished with a transparent sizing; and pigment being 16 applied to some of the surfaces of the design, beneath said sizing.

Signed at Elkhart, Indiana, this 26th day of May, 1922.

EDWARD J. GULICK.
