CHAIR SEAT.

No. 442,581. mama Dec. 9, 1890.

- UNITED STATES .ATENT- MARTIN HERZ, OF BROOKLYN, I'FV YORK.

CHAI R-SEAT.

SPECIFICATION forming part of Letters Patent No. 442,581, dated December 9, 1890.

Application iiled March 6, 1890. Serial No. 3431080. (No model.)

T0 all whom, it puny concern.-

Be it known that I, MARTIN HERZ, acitizen of the United States, residing at Brooklyn,in the county of Kings and State of New York, have invented certain new and useful Improvements in Chair-Seats; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to seats for chairs, chair-backs, ttc.; and it consists in the improved construction and ornamentation of such a seat and in the method of producing the same, as will be hereinafter more particularly set forth.

Referring to the accompanying drawings, Figure l is a plan view of a chair-seat embodying my invention, and Fig. 2 is a vertical sectional view of the same enlarged.

In the manufacture of the ordinary veneer seats in which the grain of the central or middle piece of veneer is placed at rightangles to the top and bottom pieces it is often-desirable to ornament the upper layerin imitatation of leather or other material. To accomplish this quickly and cheaply, I first form the seat l in the usual manner by gluing the three pieces together, and after the glue has dried I apply an oil-stain to one side and let it set for a few minutes, When I pass it through embossing-rollers, one of which is provided with a pattern or design of any kind cut or engraved upon its surface, which will thus compress the seat, except the portions 2,Wl1ich come under the engraved or cut-out portions of the roller, which will be thus leftin its norlnal condition. I have found by experience that this raised portion of the design or iigure which is left in its normal condition retains a much darker color than the depressed portion or background, as it were, and without attempting a full explanation of the causes of these contrasting colors, produced by the application of pressure upon stock containing but one coloring-matter, it is natural to presume that that portion or portions of the stock which come under the cut-outparts of the figure on the die or roller receiving less compression, its fibers remain less compact or condensed than the depressed portions, and consequently take up more of the coloringmatter, while the depressed portions which have the fibers condensed also have the coloring-matter thinned out or spread as it is pressed into the Wood. Again, the glue on the intermediate veneer may serve to prevent the coloring-matter from going beyond the first layer or veneer, and thereby retain it in the manner described.

rlhe seat maybe made out of only one thickness, and can then be vvarnished or otherwise treated, when it Will be ready for use.

By my improved process, as above set forth, the design or raised portion will be caused to stand out in relief and produce a most beautiful effect-as, for instance, it can be made to imitate leather With a pattern formed in the middle.

As the ber or grain of the Wood is not injured by treating it as' above described, the

upper piece of the seat is made to perform the double duty of strengthening the seatv and forming a raised pattern for the recept-ion of the coloring material, which only aects the outer surface of suoli raised portion.

One of the rollers is plain and the other one is provided with the pattern or design, and they can be used hot or cold; but as they form no part of this invention I have not shown them. By passing the wood between the calender-rolls I can emboss it and produce a very desirable article; but the design will hardly be noticeable until it is colored, when the shading thus effected will produce the desired result.

lVhile I have described my process as being applied to the ornamentation of chaire seats made of wood, yet itis obvious that the same might be used on paper or other fibrous material, and that chair-backs and various other articles may be treated in the same manner Without departing from the spirit of my invention.

Having described my invention, what I claim is- 1. The Within-described process of embossing and coloring Wood, consisting in applying a coating of oil-stain to the surface to be operated upon, and after it has set subjecting IOO the same to and producing a design or pattern thereon by pressure, substantially as specified.

2. The process of producing chair-seats, consisting, first, inN uniting two or more veneers of material with their grain crossing each other; second, applying a stain to the top layer, and, finally, subjecting the united lzty ers to and producing a design or pattern thereon by pressure, so as to imitate embossed leather and produce shading in contrasting colors, substantially as specified.

3. A chair-seat. of stained embossed .Wood the raised pattern of which appears of a different shade or tint from the body or ground, 15
