To afl/f whom it may concern:

Be it known that. I, HERMANN ROMNDER,

a citizen of the United States, and a resident.

of'Milwaukee, county of Milwaukee, State of Wisconsin, have invented new 'and useful Improvements in Wood Coverings or Facings, of which the following is a specification.

This invention relates to a novel construction of'sheets or plates of material for various purposes, and more particularly to the construction of facings, s uch as rims for vessels and railings of various kinds.

The objects of my invention are twofoldnamely, first, to provide by a novel manner of assembling certain elements a new material for the construction of the aforenamed articles which shall be not only of a strong and durable character,but also impervious to moistureand atmospheric influences, and on the other hand to provide a structure composed of a wood base which shall combine minimum weight and bulk with a maximum of strength and durability. By the accomplishment of these objects I aim to avoid difculties inherent in the use of ordinary wood for such structures as heretofore practiced, the same bein 'subject to suchl defects as checking, splitting, warping, shrinking, swelling, and generally disintegrating.

To attain these objects, my invention` involves two main features-to wit, first, the combination of thin wooden or fibrous veneers or plates placed in juxtaposition with crossed or reversed grains with a species of, waterproofing compound which serves both as an adhesive and a protection againstabsorption of moisture. The manner in which these are combined will be hereinafter described. The other feature by which I attain my objects resides inthe form into which I press the material so produced to produce a maximum of strength and durability.

My invention maybestbe understoodfrom a consideration of'the following description, reference being had to the accompanying drawings, in which- Fi ure 1 is a seat uilt accordlng to my invention. Fig. 2 is a transverse section thereof on the line w. Fig. 3 is a plan view of a bath-tub rim according to my invention. Fig. 4 is a transverse section throu h one side of either of the forms shown 1n Figs. 1 and 3 on the line and on an enlargedscale.

In these drawings every reference-letter refers always to the same part.

. and rigidity. lan view of a water-closet l The structure of the material from which my Invention is built is best shown in Fig. 4.

In order to form this material, several sheets of fibrous material, generally wood veneer a b c, are taken and combined with a waterproof cementing composition in such mannerv that the composition thoroughly impregnates to expand, combined with the pressure whichl acts to squeeze it away from the surfaces between the layers of veneer, said cement is thus` forced to enter `the pores or interstices of the wood, com letely fillingthe'same. At the same time tiewood bein thus moistened and. rendered pliable it 1s caused by suitable dies or other means to assume various shapes in accordance with the articles which are to be made from it. Several of these articles are shown in the drawings. In Fic'. 1,for example, the seat Ais given a doubIe curvature around the rim or annular portion thereof, the edges being bent downwardly,

so that it is convex upon its upper surface and concave on its lower surface, the back d, however, being left flat for the attachment of hinges. It will be understood that to cause the wood to assume such shape some fibers others compressed and forced together, whereby the original surface of single curvature becomes a surface of double curvature, which being non-developable upon a plane, as is well understood, is one of Great strength In articular it 1s to be noted thatgthe surface o double curvature given to the seat Ain Fig. fr and to the rim B in Fig. 3 is that known geometrically as a torussurface-to wit, one generated bya curved line moving in a curved direction transverse to its own plane-and such surface, as is well understood, is of particularly eat rigidity and enables me to accomplisIir my object of combin-inor a maximum of firmness and 'are necessarily stretched or extendedland IIO strength witli a minimum of weight. In a j fous, and indivisible structure,

similarmanner the princi les of my invention may be applied to all) manner of Wood trimmings, facings, coverings, and other objects into which the material While in the moist and pliable condition is capable of being bent by the combination of heat and pressure.

After being molded or formed to the proper shape, the heat and pressure being removed, the finished article is allowed to dry and thereafter becomes unchangeable except by actual breakage, being no longer subject to atmospheric influences, because the thorough impregnation of the Wood by the cement makes it a substantially integral, homogene- The waterproof cementing composition binds the Whole together, while repelling any moisture Thus it cannot Warp `or split, to which action comound veneers generally as'heretofore made llave always been subject. The cement serves not only to hold one veneer to another', but also to hold the fibers of each veneer to each other, thus acting as a cohesive as Well as an adhesive.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is+ l 1. A rim for basins and the like comprising a plurality of annular plates of veneer united by cement, and caused by heat and pressure to assume a surface convex on the upper side by the downpressing of the edges thereof.

2. A rim for basins and the like comprising a plurality of annular fibrous plates united by a Waterproof cement, and caused by heat and pressure to assume a convex upper surface and to become impregnated throughout Withsaid Waterproof cement.v y 3. An improved closet-seat comprising a plurality of annular fibrous plates united by cement, the edges whereof are pressed downwardly under heat and pressure whereby the whole assumes a convex upper surface.

4. An improved closet-seat comprising a plurality of annular fibrous plates united by a Waterproof cement which is caused to thoroughly impregnate said plates from the inner faces thereof by heat and pressure whereby it is rendered impregnable to moisture from he outside, and bent to a convex upper surace.

5. A rim for basins and the like com rising three annular plates of Wood veneer raving their grains crossed, the 'Whole combined, united and thoroughly impregnated with a Waterproof cementing compound whereby they areV rendered impregnable to moisture from the outer surface, andthe Wholey caused by heat and pressure to assume a convex upper' surface. j

Signed at the city and county of Milwaukee, State of Wisconsin, this 423d day of May, 1904.
