FINISH METAL ARTICLES AND METHOD OF PRODUCING THE SAME.

Application filed February 10,1923. Serial No. 618,378.

To all whom it may concern:

Be it known that I, IVI'LLIAM L. KRAY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement inFinish for Metal Articles and Methods of Producing the Same, of which the following is a specification.

This invention relates to the decoration or surface finishing of articles, such for example, as bedsteads and other articles of fur niture made of polished brass or analogous metal.

One object of the invention is to produce brass or analogous polished metal articles, particularly articles of furniture which are decorated or finished so as to match or harmonize with Wooden furniture or articles of a particular style or finish. For instance, by my invention an article of furniture, such as a brass bedstead, can be finished in part or in Whole in imitation of Oircassian walnut or other wood to match other articles of furniture made of such wood. Another object of the invention is to finish or decorate brass or analogous metal articles so that they will have the same appearance as if made in part of polished metal and in part of wood.

In the accompanying drawings:

Fig. 1 is an elevation of a bedstead end frame finished or decorated in accordance with my invention.

Fig. 2 is a fragmentary elevation on an enlarged scale of a metal tube decorated or finished in accordance with my invention.

The tube represented in Fig. 2 is a cylindrical, polished brass tube such as used in brass bedsteads and other articles of furniture. Ordinarily such tubes are polished or rubbed lengthwise thereof so as to produce a polished surface, indicated at 10 in the drawings, in which the fine abrasions that produce the polished surface run in a generally lengthwise direction. A coating of paint or pigment contrasting in color tothe polished metal surface is then applied thereto as indicated at 11, and this coating is wiped off or partially removed in places before it sets or hardens so that the underlying polished metal surface, which is of a lighter or contrasting color, will show through more or less in the wiped places, thereby producing a design of contrasting portions, which design is preferably such as to represent the ornamental grain of hard wood. For instance, by using a coating hav- .ing the proper brown shade, the polished duce a very close imitation of a polished piece of this wood. The lengthwise polishing abrasions of the underlying metal surface augments the imitation. Other woods can be imitated in a similar manner by the use of paints or coatings of appropriate colors. Metal articles of furniture, or other metal articles, can, therefore, be finished to match furniture or other articles made of one or another kind of wood. The component tubes or frame members of the metal article can be thus finished throughout their length, as in the case of the curved top rail 12 of the bedstead end frame shown in Fig. 1, or if desired, portions only of the tubes are finished in this way, as in the case of the corner posts and filler tubes shown in Fig. 1 and the tube shown in Fig. 2.

When this imitation wood finish is used for only a portion of the length of the tube, the ends of the coating can be readily made straight by wiping off the end portions of the coating while turning the tube in a suitable lathe or machine.

13 represents circumferential, ornamental polished bands produced by polishing the metal surface of the tube circumferentially while turning it in the lathe. These polished bands are preferably used at the ends of the imitation wood finish, where this extends for only a portion of the length of the tube, but they can be omitted if preferred.

The ornamental surface or finish, pro duced as described, is preferably protected and preserved by a coating of lacquer such as commonly used on polished metal articles.

I claim as my invention:

1. A finish for metal articles which consists of a polished surface produced on the metal, and a coating on said polished surface which contrasts in color therewith, said polished metal surface showing through said coating in places and producing a wood grain effect.

2. A finish for metal articles which consists of a polished surface produced on the metal, and a coating on said polished metal surface, said coating being more or less removed in places and permitting said metal surface to show through at such places to produce a design.

3. A finish for metal articles which consists of a polished surface produced on the metal, and a coating of contrasting color with said surface Which covers a portion only of the area of said polished surface,

in color with said polished metal surface, and removing more or less portions of said coating, thereby permitting said polished metal surface to show through said coating in places and produce a design.

5. The hereindescribed method of finishing metal articles, consisting in polishing the surface of the article, applying to a portion only of the area of said polished surface a. coating which contrasts in color with said polished surface, and removing more or less port-ions of said coating to permit said polished metal surface to show through said coating in places so as to produce a woodgrain eifect,thereby giving said article the appearance of being composed in part of wood and in part of metal.

WILLIAM L. KRAY.
