INLAID WORK AND PROCESS OF IViAKING THE SAlVIE.

SPECIFICATION forming part of Letters Patent VNo. 268,469, dated December 5, 1882.

l Application tiled September 2S, 1882.v (No model.)

To alt whom tt may concern:

Be it known that I, VILLIAM C. EDGE, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Inlaid Work and Process of Producing the Same, of which the following is a specification.

Figure l represents a face view of the stamped metal from which my improved inlaid work is made. Fig. 2 is a cross-section of the same. Fig. 3 is a plan view thereof after the projections have been cut away to show the lower metal. Fig. 4 is a cross-section thereof, and Fig. 5 is a cross-section showing the inlaid work made from three thicknesses `of metal.

Heretofore inlaid work, showing two or more kinds of'metal in a metallic ground, was produced by cutting into the metallic ground, and then filling the spaces thus obtained with the metals of different color, so as to produce therequisitedesign. Damascene-work, where steel is inlaid with gold or brass, and other costly and beautiful specimens of inlaid work, were thus made and were highly prized, because of their great beauty and durability but the cost of production was necessarily very great, and it requiredthe most skillful attentionto produce a perfect specimen of such inlaid work.

Myinventionconsists in producing the same effect as Damascene-work, or any other suitable effect that may be desired, bysuperposing` the metals-of-whichthe work is to becom-` posed inslices 'one upon the other,"then embossing them sopas -toeraise the lower slice of metal wlie'r itmismembossed into the plane of the upper slice, anti thehntiling orwcutting away suchportionsof the embossed projections as are desired to produc ethe design. Thus, for example, where only two colors are desired to beshown-namely, one onWthe background of the other-Ttwo slices, a b, of metal are used, as in Figs. l, 2, 3, and 4. These two slices are soV placed that the one, c, for the groundwork shall be on top and the other, b, for the ornamental scrolls, Ste., at the bottom. The two slices c b are united by what is known as platin g,orin any other proper way to permanently remain in connection with one another, and they are then placed into an embossing# machine, which will strike up such ornaments as it may be desired to have struck up for the production ofthe requisite design. (Slee Figs. l and 2.)

The embossing-machine is to operate. in such a way that the projecting parts of the lower plate, b, will extend into the plane of the upper plate, a, as is clearly shown in Fig. 2. The metal havingbeen brought into the condition shown in Fig. 2, the embossed projections are next filed off, more or less, so that thev covering of the plate c, above the stamped-up portions ofthe plate I), is removed, thus leaving a trace or scroll ofsuitable outline ofthe lower metal visible in the background ofthe upper.

It will be seen that the production of inlaid work on thisplan is not expensive beyond the mere cost of the metal itself', and that the most beautiful effects can thus be produced. The more slices of metal are used the richer of course will be the effect. 'lhus in Fig. 5 are shown three slices, c b c, united togethersay the upper slice, c, of steel, the next lower slice, b, of gold, and the lowermost slice, c, of silver or white gold.V When these slices have been properly plated or united, they are stamped up in the embossing-machine, so that the metal of the lowermost plate, c, is carried into the plane ofthe uppermost slice, c, at such parts where it is desired to showtthe colorof the lowermost plate. At other parts where that color is not to be brought out, the raise produced by the embossing'machine must suflice to bring the metal of the slice i) into the plane of the slice a. After the embossing-machine has done its work, therling-odcommences and produces on the surface ofthe steel, which thus becomes perforated, outlines ofgold or outlines of gold bordered with silver, or, if desired, outlines otsilver only. The embossed parts may be tiled off entirely, ifdesired, so as to leave the upper surface ofthe plate c quite smooth when thework isfinished; or suitable parts of the embossing may be allowed to remain raised, so as to heighten the effect. The lower slice may be made of sections of different metals, placed side by side, to increase the effect.

I do not limit myself to .any kind of metal from which this work can be made, nor to any mode ofjoining the two or more slices7 nor to IOO any kind of embossing-machine in which the slices aire embossed, nor to any method of cnttiug off the embossed projections so as to show the lower metal in the upper, as this ina-y be done either by ling, shearing", etching, or otherwise.

-I claimp 1. The method herein described of producing inlaid work, which consists in intimately connecting two or more slices of metaLin then embossing them so as to bring parts of the lowerrnost slice into the plane of the uppermost slice, and in then cutting down the em- 0 scenico lower slices, each of which extends beneathI the slice a, and projects also into the perforaktions of scid slice a, substantially as described.
