OBNAHEN'IAL ARTIQLES OF MANUFACTURE AND METHOD PRODUCING THE SAME.

Application filed August 2?, 1936. Serial No. 131,975.

This invention relates to improvements in ornamental articles of manufacture and to the m thod of producing the same.

The object of the invention is to ornament articles of manufacture such as furniture, radio cabinets, musical instruments, etc., by combining a part of such structures, such as a desk top, with an inlaid desi n comprised of a metal plate containing the desi it- 1 seif and a veneer of wood inlaid in t e design, the desk to in the illustration here iven forming the ass with which the metal esi n and the veneer will be incorporated. The invention further consists in the 5 method by which this article is fabricated as will be hereinafter fully stated.

In the accompanying drawings Figure l-is a plan view of say a desk top with my invention applied thereto;

Figure 2 is a sectional View; Fi ure 3 is a plan view of the metal plate showing the design.

Figure 4 is a s set of veneer; Fi ure 5 is an inverted plan view of the meta plate and the veneer;

Fi ure 6 is a top plan view of the veneer and t e design;

Figure 7 is a sheet of celluloid.

Let it be supposed that a desk top is to be ornamented with an' inlaid design. Such a top is indicated at 1 in the drawings, as best seen in Figure 1. On this top I mount a sheet of veneer, composed of one or more pieces as may be needed. This sheet is inas dicated at 2.

Before the veneer is ap lied to the desk top the design shown in igure 1 is fabricated. This design is -shown in Fi ure' 3 where a plan view is given of a'met plate 40 3 having a design wrou ht thereon either by the use of a die by which to stamp the design on the metal plate or by the well known rocess of etching the design into the plate. In either case the late is onramented with the design as clear y seen in Figure 3.

In Figure 4 we have illustrated a sheet.

of veneer of wood re resentative of the veneer that is to be in aid in the design and to be ap lied to the top of the desk in the example ere being given. In Figure 5 we have illustrated an inverted plan view of the metal plate and the veneer after they have been joined together by one of the ste s of the method. Figure 6 I have shown a top looking down on the veneer wit lan view the. de-.

will take on the appearance indicated in Figure 1 where the top of the desk is shown w th the design wrou ht in metal and in: laid with wood and t e veneer applied to the top. 7

Thus it will be seen that the article comprises as its base apart of the furniture or other structure, the wood veneer overlying the top and the metal design late occupying a place between the top and the over] 'ng veneer, with that part of the veneer w ich overlies the tracery of the desi removed to expose the design, and with t at part of the veneer which is over the de ressions surrounding the tracery inlaid own in such depressions.

will refer now to my method of roducmg this article, I assume that the (idsk top or other structure to be ornamented has been prepared and is read for the application of the veneer and the esign. The particular design having been decided u on it is wrou ht in the metal plate 3 eit er by the use 0 a die containing the design or by the use of the well-known etching process by which the design can be formed on the plate. This being done the metal plate is treated to a light deposit of. latent celluloid solvent such as camphor Sap plied either b deposit from a volatile so ution or by sub imation) and a sheet of dry celluloid is superimposed upon the treated metal. Then the'wood veneer which has also been previously treated with a solvent such as butanol, 1s laced upon the cellouloid sheet which now ies on the metal plate. The metal plate, the celluloid' and t e veneer being now together are placed in a press and subjected to heavy pressure, such as 800 to 1000 pounds per s uare inch for a period of from ten to fi teen minutes, accompanied by heat applied to the press so as to pro uce a temperature of from 115 C. to 125 C. in the plate, celluloid and veneer.

The result of these steps is depress the veneer into the design to give the appearance shown in Figure 6 where the veneer is represented as having been depressed into the recesses about the trace of the design and to overlie the raised sur ace constituted lilllh ill till

ill

by the traeery. ilnd the same time that is being attected, the solvents and the heat acting on the celluloid will have re duced the tacos thereot to a gummy or sticlr v state, whereby it constitutes a most eltective udhesive between the rectal plate and the wood veneer.

'lhcn the now composite article is with drawn them the press and the taco out the veneer ground or dressed oft to the entent necessary to remove the wood trons shove the tracerv ol' the design so us to enpose the design and lenve the wood around the design and in the depressions between the lines out tracer-y.

This condition is shown in the linished product represented in Figure l where the design is shown inlaid with the veneer and where the veneer and the metal plate have been united to the desk top Tthe method of uniting the veneer and the metal plate may be the usual one or uniting veneers to furniture such as by the use ct an adhesive and e. suitable pressure to edect the union of the veneer and the top.

ltgein, the heel; ot the metal plate, in order to prevent any undue encrescence oli' it beyond the veneer surtace, is either dressed ott' to reduce the thickness of the plate so that there will be no appreciable encrescence termed by it, or the plate is originally very thin, say ot a thickness of not exceeding or less than that of the veneer itselt, except that part oi the plate which is constituted ot the tracery oi the design which, of course, must be thiclr enough to allow the design to stand out in reliet in order that the wood 111E137 be inlaid down in the spaces shout the tracery.

lit will now be seen that-by my method l are enabled to beautitully and cheaply ornainent various articles oi manufacture with inlaid work, and that the resulting product comprises as the base of the article the structure to be ornamented, as the dosh top, the hidden metal plate with its design wrought thereon and the veneer, which in port is inlaid in the design and as to the remainder terms the finished surlace ot' the article.

it will be understood that l desire to coin prehend within my invention such noodilicetions as may be necessary to adapt it to varying conditions and uses.

Having thus tully described my invention what ll claim as new and desire to secure by letters Patent, is:

l. The herein described product, consisttoilette design, and e veneer ot wood overlying the article and the plate with the'adhesive intervening, and inlaid in the depressions about the design and removed over the tracerv to expose the design, the wood and rectal being united by a binder 0t celluloid.

3. The herein described method of ornameeting an article ot manufacture, consist ing in preparing the part ot the article to be ornamented to constitute a base; in coatin the said piece with arsolvent for celluloid; in tabricating a design on a metal plate; in coating the metal with a solvent for celluloid; in piecing a sheet of celluloid bctween the metal and veneer; in laying in the design a wood veneer by the application ot pressure; in dressing oil the portions ol' the veneer which overlie the tracery ot the design. to expose the design and leave portions of the veneer inlaid in the depressions around the design; and in applying and securing the veneer with its incorporated design to the surface oi. the article to he ornamented.

l. 'lhe herein described method of ornainenting an article of manufacture, consisting in preparing that part oi the article which is to be decorated; in lubricating a design on a metal plate; in applying to the plate an adhesive comprising celluloid; in overlaying the plate with its adhesive with a wood veneer; in subjecting these parts to pressure and heat to force the veneer into the depressions in the plate which surround the design and partially bulge the tacery oi the design through the'veneer; in later dressing oil those portions 01 the veneer which so overlie the tracery to expose the design and leave the veneer inlaid about it; end in applylng and securing the veneer with contained design to the surface to he ornamented.

in testimony whereot, It alliv. my signature.
