BARK VENEER.
Application filed January 11, 1928. Serial No. aam.
This invention relates to a wood veneer in which the upper surface is made of the bark of certain trees cut into slabs at right angles to its fibre, the resultant product havlng an appearance much like a so1id color heavy pile rug, but with greater wear ng qualltles.
It has been found that the bark of the California Redwood is especially adapted to the production of this material and 1t 1s especially valuable for floors, desks and table tops and for many other kindred uses.
I have found in practice, that when the bark of the Sequoia or California Redwood is cut transversely to the fiber that 1tmakes an excellent surface for this character of work.
The bark of other trees where it is fibrous enough to hold together properly may also be used for this purpose, such bark 1s found on the cedar, spruce and fir, where large trees are cut may also be used.
Other objects of the invention w1ll appear as the description proceeds.
An embodiment of the invention is shown in the accompanying drawings 1n which the same reference numeral is applied to the same portion throughout, but I am aware that there may be modifications thereof.
Figure 1 is a sectional view of the prod act, and
Figure 2 is a plan view, and
Figure 3 is a plan view of a sectlon of the material made up of several blocks of the bark arranged differently, so as to produce a Mosaic effect with the individual bark lines crossing each other to produce a varied effect in the light, somewhat similar to the velvety effects produced in ordinary mosaic block veneers.
The veneer back ordinarily consists of three layers of a common veneer 1, 2 and 3, backed with a tar paper 4 to keep out moisture, and
on the upper layer of wood a comparatively thin layer of end cut bark 5 is then glued.
The bark is transversely cut with very sharp saws, and is then glued down, after which it is brushed with a stiff bristle or wire brush, to bring up the nap and is ready for use.
The material is cutwith a saw that has been considerably set:in the teeth, and this produces a more or less wavy effect in the surface, because the more fibrous parts of the material tend to be longer than the harder arts of the material which are cut sliglrigly deeper. The difference amounting to n 1/32 to 1/16 of an inch in some specimens,
as illustrated in Figure 1 at 6.
to each other'and substantially at ri ht an-- igures gles to the appearance of the fiber in 11 and 13.
The material itself has a series of indefinite curved lines on its surface, which lines extend substantially parallel to each other, and when reversedin position give difierent light effects even from the same piece of bark.
The veneer when viewed at various angles, gives a peculiar moire effect, somewhat like irregular velvet.
What I claim is as follows, but modificatlons may be made in carrying out the invention shown in the drawings and in the above particularly described from thereof, within the purview of the invention.
1. An ornamental veneer comprising a solid backing covered with water proofing on one side, and a tree bark covering perma: nently secured to the other side thereof, said tree bark being cut transversely of the length of the fiber into comparatively thin sheets, the several parts being secured on the backing closely together to produce a substantially uniform surface.
2. An ornamental veneer comprising a backing and a' tree bark covering secured thereto, said bark being cuttransversely of the fibers thereof into comparatively thin layers and secured to said backing, said portions of the surface material being differently arranged to produce a moire effect with the ends of the fibers.
3. An ornamental veneer comprising a solid backing and a comparatively thin sheetof veneer carried thereby and secured thereto, said veneer consisting of redwood bark cut transversely of the length of the fibers with the ends of the fibrous portions 011 one side glued to the backing, and the ends of the fibers of the outside surface of the veneer differently arranged whereby a velvety moire appearance is given to the product.
In testimony whereof I have hereunto set my hand this 30" day of December A. D.
